Anatomic Variations of Extrahepatic Bile Ducts and Evaluation of the Length of Ducts Composing the Cystohepatic Triangle
Provedor de dados: 77
Autores: Cachoeira,Eduardo; Rivas,Antonio; Gabrielli,Carla.
It is of paramount importance for surgeons to have a thorough knowledge of the normal anatomy of the extrahepatic bile ducts and its variations due to the high frequency with which they perform in this anatomic site. The cystohepatic triangle, or Calot's Triangle, is bound by the cystic duct, common hepatic duct, and the hepatic border; therefore, its surface area depends on the conformation of these ducts and is closely linked to surgical procedures performed in this region. It has been reported that the length and the position of these ducts may be related to the formation of bile duct stones, Mirizzi's syndrome, and bile duct cancer. Thus, the present work aims to analyze the configuration of the extrahepatic biliary tree and its possible variations, as...

The aim of this study was to accurately measure acromial morphology in order to describe the anatomical patterns of its subtypes and to conduct a survey of the literature regarding the relationships between morphological subtypes and their related diseases. We photographed scapulae from the Institute of Anatomy, University Severino Sombra, and analyzed the images using Image-J Software®. The average acromial angle was 139.23° ± 2.781, with no significant difference between the right and left sides. There was a positive correlation between the acromial angle and the angle of the spine of the scapula. The correlation mentioned above plays an important role in disorders of the shoulder-particularly impingement syndrome-which reinforces the importance of...

Provedor de dados: 77
Autores: Ekinci,C; Tahaoglu,A. E; Yavuz,D; Deveci,E; Aktas,A; Yilmaz,T; Yumusak,Ö; Yükselmis,O.
Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may...

Miedo y Deshumanización: una Visión Crítica sobre la Realidad Cotidiana en el Laboratorio de Anatomía Humana
Provedor de dados: 77
Autores: Castilho,Marco Antonio Sant´Ana; Oda,Juliano Yasuo; Sant´Ana,Débora de Mello Gonçales.
La anatomía humana tiene como importante fuente de estudio al cuerpo humano. Ella utiliza cuerpos no reclamados, usualmente de indigentes, cuerpos entregados como un beneficio a la sociedad sin nada pedir nada a cambio, siendo dignos de pleno respeto. Sin embargo, preocupa que la muerte no es mirada socialmente como algo natural a la vida, llevando la convivencia en el laboratorio de anatomía humana a un estado de miedo, angustia y repulsión. Con eso se produce un mecanismo de negación, que puede generar deshumanización hacia la pieza anatómica. Ser confrontado con la muerte de otro, es lo mismo que confrontarse con nuestra propia muerte. En este contexto, los profesores y técnicos tienen una gran responsabilidad en discutir y reflejar la cuestión, de modo...

Predicting Horse Skin Weight from Carcass Weight
Provedor de dados: 77
Autores: Parés i Casanova,P. M.
A study was conducted to provide information on the skin weight of Pyrenean horses and to determine whether there is a measurement to predict this based on carcass weight. Hot carcass weight (HCW) and fresh skin weight (SW) were recorded for 58 horses aged 12 months entering a Catalan commercial slaughter facility between September 2009 and June 2010. Data on the breeder, age and coat characteristics were collected and subsequently collated for each animal. Prior to analysis, horses were subdivided into sex and coat groups. Data did not differ (P &lt; 0.001) among these. The absence of differences in SW could be viewed as a reflection of limited nutritional differences between seasons. Regression procedures were used to develop equations to predict SW from...

Effects of Preweaning Polysensorial Enrichment upon Development of the Parietal Cortical Plate of Undernourished Rats: A Stereological Study
Provedor de dados: 77
Autores: González,Héctor; Adaro,Luis; Hernández,Alejandro; Fernández,Víctor.
This investigation was undertaken in order to quantify the effects of early polysensorial enrichment on the development of cortical pyramids, located in the parietal cortex of rats simultaneously submitted to protein-energy undernutrition. A short period of stimulation during suckling significantly decreases the cellular density in the cortical plate (phylogenetic-ontogenetic evolutionary index). Results suggest that the cerebral cortex develops according to a sophisticated neuronal network, which exhibits a notable degree of structural specificity, regulated by genetic and environmental clues. The most obvious prediction is that environmental influences are probably transduced as a structural expression in the developing parietal cortical plate.

The Recurrent Laryngeal Cardiac Nerve in Fetuses
Provedor de dados: 77
Autores: De Gama,B. Z; Lazarus,L; Satyapal,K. S.
The recurrent laryngeal nerve has been reported to supply cardiac branches to the cardiac plexus. A review of anatomical literature on the existing term used to describe these branches revealed that varying interpretations and descriptions exist among various authors. Therefore, this study aimed to investigate the origin and incidence of branches from the recurrent laryngeal nerves to the cardiac plexus and their connections with sympathetic cardiac nerves. The sample comprised 40 cadaveric fetuses (n=80) (gestational ages: 16-30 weeks). The recurrent laryngeal cardiac nerve was described as the cardiac branch that originated directly from the recurrent laryngeal nerve and reached the superficial or deep parts of the cardiac plexus. This study found the...

This study was aimed at determining the morphology of the aortic arch in the sparrowhawk. For this purpose, arteries near the heart of six sparrowhawks were assessed. Latex injection method was applied to the three materials and barium sulphate solution was injected into the aorta for angiography in three other materials. It was observed that two major arteries arose from aortic arch in the sparrowhawk: the left brachiocephalic trunk and the right brachiocephalic trunk. These trunks were contiguous arteries but separately originated from the aorta. The brachiocephalic trunks were divided into the common carotid and subclavian arteries after their origins. First, the common carotid arteries are given off by the brachiocephalic trunks. The common carotid...

Phenytoin (diphenylhydantoin, dilantin) has been the chosen anti-convulsive for the treatment of sudden disorders since the late 1930's. Several epidemiological and clinical studies in human beings showed an increase in malformations in descendants of which mothers took phenytoin during gestation, such as cranio-facial development and growth abnormalities, distal phalangeal hypoplasia, and light or moderate mental deficiency. This work had the goal to study the lingual mucosa, under histopathological and morphometric standpoints, in rat fetuses which were given an intraperitonial injection, consisting of a unique dose of phenytoin (70 milligrams/kilogram of their weight). Being that, we included the examined material in paraffin, 6 micrometers thick, and...

Arsenic is a testicular environmental toxic. Melatonin (Me), being a potent antioxidant, may reduce the damage caused by arsenic in male fertility. The effects of daily oral exposure of Sodium Arsenite (As; 7.0 mg/kg/bw); Melatonin (Me, 10.0 mg/kg/bw); Me (10.0 mg/kg/bw) plus As (7.0 mg/kg/bw), and Negative Control (NaCl 0.9%) in male CF-1 adult mice were assessed in acute (8.3 days), chronic (33.2 days) and recovery (66,4 days) of testicular damage. We evaluated changes in testicular weight and histopathological, morphometric measurements, expression of COX-2 and Androgen Receptor (AR) antigens and lipid peroxidation levels. Treatment resulted in decreased tubular diameter and AR expression, and increased: interstitial area, luminal diameter, COX-2...

Provedor de dados: 77
Autores: Olave,E; Galaz,C; Retamal,P; Cruzat,C.
Los nervios cutáneos dorsales del pie se originan a partir del nervio fibular superficial (NFS), después que éste pasa desde el compartimiento lateral de la pierna a través de la fascia profunda, para luego distribuirse superficialmente en el dorso del pie. A veces, el nervio fibular superficial se divide precozmente, por lo que estos nervios se originan profundamente y con una disposición diferente. Con el propósito de dar a conocer en estos casos, los niveles de origen de los nervios cutáneos dorsales del pie y el punto de penetración en la fascia profunda de la pierna, se estudiaron 16 muestras de individuos, chilenos, adultos, fijadas en formaldehido al 10%. En 2 de ellas, su origen se observó a un nivel alto, cerca de la parte proximal de la fíbula....

Autores: Kosif,Rengin; Sahin,Bünyamin; Gürel,Safiye.
Cerebellum regulates motor control and physical coordination. It is known that when eye and hand need to be worked in combination, cerebellum is active and it provides coordination between eye and hand. Cerebellar cortex atrophy appears with dismetry and saccadic eye movement. If there is no stimulant related to vision, how cerebellum is adopted under this circumstance? In order to explore this, 27 male and 16 female volunteers with bilateral congenital blindness were compared with 35 male and 33 female healthy volunteers in this study. MR images of cross-sectional sequential cerebellum of volunteers with 1.5 mm thickness were realized in coronal plane. The surface area of apparent cerebellum seen in cross-sections was calculated by using Onis (Ver. 2.1)...

Teratogenic Effect of Ethylene Glycol-Methyl Cellosolve Mixture in Rats.: I. Reproductive Damage
Provedor de dados: 77
Autores: Arteaga-Martínez,Manuel; García-Peláez,Isabel; Aguirre-Luna,Oswaldo M; Saavedra-Ontiveros,Dolores.
We investigated the reproductive damage and teratogenic effect of an ethylene glycol-methyl cellosolve mixture on gestating Wistar rats, which received a daily intraperitoneal dose of different concentration of the mixture on day 8 of gestation until day 20. In rats treated with the mixture the number of live fetuses decreased and reabsorptions increased with increasing concentrations of the mixture, as well as the number of abnormal fetuses. We conclude that the ethylene glycol-methyl cellosolve mixture possesses a higher teratogenic potential than each of its constituents separately, producing reproductive damage, external fetal abnormalities, growth delay, and increased fetal death.

Provedor de dados: 77
Autores: Silva Júnior,L. M; Alexandre,M; Gonçalves,L; Silva,F. S; Caetano,A. G.
During anatomical dissection of the abdominal cavity of an adult male corpse, a changing pattern of vascular supply of pancreas and of the transverse colon was observed. The inferior pancreatic artery and the middle colic artery arose from a common trunk of the superior mesenteric artery. Moreover, the lienal artery did not direct a dorsal branch to the neck of the pancreas, but rather sent two greater pancreatic arteries (proximal and distal) to the body of the gland and one caudal artery to the terminal portion of the pancreas. We also observed a large communicating branch between the proximal portion of the middle colic artery and the ascending branch of the left colic artery, previously described as artery of Moskowitz. Based on these data, clinical...

Provedor de dados: 77
Autores: Trujillo,Erick; Morales,Rolando; Roa,Ignacio.
La reacción y reparación de la dentina depende del número de células presentes en la pulpa, dentro de éstas fibroblastos. Los métodos diseñados para obtener una estimación fiable de la cantidad de elementos celulares de la pulpa han sido subjetivos y sesgados, sobre todo al evaluar los cambios cuantitativos y potencial capacidad reparadora en presencia de caries. El objetivo fue estimar y comparar cuantitativamente las densidades de número, volumen y superficie de fibroblastos en pulpas sanas y con diagnóstico de pulpitis reversible producto de caries en dientes humanos jóvenes. Se utilizaron dientes premolares humanos obtenidos de exodoncias, divididos en un grupo sano y cariado, los cuales fueron fijados y posteriormente descalcificados con ácido nítrico...

Homoplasies, Consistency Index and the Complexity of Morphological Evolution: Catfishes as a Case Study for General Discussions on Phylogeny and Macroevolution
Provedor de dados: 77
Autores: Diogo,Rui.
Catfishes constitute a highly diversified, cosmopolitan group that represents about one third of all freshwater fishes and is one of the most diverse Vertebrate taxa. The detailed study of the Siluriformes can, thus, provide useful data, and illustrative examples, for broader discussions on general phylogeny and macroevolution. In this short note I briefly expose how the study of this remarkably diverse group of fishes reveals an example of highly homoplasic, complex 'mosaic' morphological evolution

Differential Effect of the Route of Inoculation of Rabies Virus on NeuN Immunoreactivity in the Cerebral Cortex of Mice
Provedor de dados: 77
Autores: Rengifo,Aura Caterine; Umbarila,Vanessa Jazmin; Garzón,Mary Janeth; Torres-Fernández,Orlando.
Rabies is a lethal disease caused by a neurotropic virus that produces inconspicuous morphological changes hardly observable with conventional histopathology. The fatal outcome caused by rabies could be attributed to specific biochemical changes that severely impact neuronal function. The neuronal nuclear protein (NeuN) has become a widely used neuronal marker for the research and the histopathological diagnosis of nervous system diseases. To evaluate the distribution of the protein NeuN in the motor cortex of normal and rabies-infected mice adult ICR mice were inoculated with rabies virus either intramuscularly or intracerebrally. Rabies-infected mice were sacrificed at the terminal stage of the disease. Control mice were also euthanized at the same age....

Metallothionein: An Overview on its Metal Homeostatic Regulation in Mammals
Provedor de dados: 77
Autores: Sakulsak,Natthiya.
Metallothionein (MT) is a ubiquitous protein with a low molecular weight of 6-7 kDa weight and it was first identified in the kidney cortex of equines as a cadmium (Cd)-binding protein responsible for the natural accumulation of Cd in the tissue. The mammalian MT contains 61 to 68 amino acid residues, in which 18 to 23 cysteine residues are present. The expression of MT starts by binding of metal transcription factor-1 (MTF-1) to the regulative region of MT gene called metal responsive elements (MREs). The induction of MT through the MREs region can be initiated by several metal ions such as zinc (Zn), copper (Cu) and Cd. However, Zn is the only heavy metal which can reversibly and directly activate the DNA-binding activity of MTF-1. In mammals four types...

Autores: da Mata,João Roberto; da Mata,Fabiana Ribe; Aversi-Ferreira,Tales Alexandre.
Inadequate ossification of the interparietal region induces the appearance of interparietal and wormian bones, also associated with genetic factors. The formation of the interparietal bone depends on the separation of the intermediate segment from the lateral plate by the transverse occipital suture, which means that this bone is formed by the medial and lateral plates. Wormian interparietal bones or epactal bones are located within the interparietal region, being single or multiple, and are located in the upper central region of the interparietal region, the sutural bones, however, are formed from additional ossification centers that can occur in near sutures. The aim of this work was to macroscopically evaluated the presence of changes in the structure...

Impronta Genómica y Desarrollo Embrionario
Provedor de dados: 77
Autores: Reig,German; Concha,Miguel L.
En los organismos diploides, cada gen autosómico está representado por dos copias, o alelos, heredados de cada progenitor al momento de la fecundación. Para la gran mayoría de los genes la expresión ocurre desde ambos alelos de manera simultánea. Sin embargo, un número reducido de genes (menos del 1%) es afectado por un proceso de impronta genómica. Este proceso determina que la expresión del gen sea dependiente del origen parental, es decir, se comporte de manera distinta si su origen es materno o paterno. La metilación del ADN es una de las modificaciones epigenéticas mejor estudiadas y su participación resulta esencial durante el establecimiento de la impronta genómica. Si bien los patrones de metilación a nivel genómico son estables y heredables,...

Although brain development is most active during the intrauterina period of life, the processes of myelination and arborization affect the structure of the brain throughout childhood and adolescence. Brain development is also very active in the early years of a child's life, and continues to be so for approximately 15 years after gestation. Volumetric changes in the brain are effected by sex. Understanding the variability of human brain volume during development is important for the interpretation of childhood neuroimaging studies. Hence the aim of this study is to determine the effects of sex difference on brain volume (BV), lateral ventricle volume (LV) and the ratio of brain volume and lateral ventricle volumes as a percentage (RLBV%) of 90 healthy...

Provedor de dados: 77
Autores: Pillay,P; Partab,P; Lazarus,L; Satyapal,K. S.
The formation of ansa cervicalis (AC) is somewhat complex with both its course and location along the common carotid artery and internal jugular vein (IJV) varying. The aim of the study was to document the anatomy, formation and variations of AC. Forty fetuses (gestational age: 15 to 28 weeks) were obtained from the Department of Clinical Anatomy, Westville Campus, UKZN. A detailed micro-dissection of the posterior triangle of the neck and AC were completed using standard micro-dissecting instruments. Results of the formation of AC, its relationship to IJV and variations were recorded. The superior root was identified as a long willowy nerve that branched from the hypoglossal nerve, descended on the carotid sheath, anterior to the common carotid artery and...

Characterization of the Uterus and Mammary Glands of the Female African Giant Rats (Cricetomys gambianus, Waterhouse) in Nigeria
Provedor de dados: 77
Autores: Akinloye,Adebayo Koyuum; Oke,Bankole Olusiji.
Morphology of the uterus and mammary glands were studied in sexually matured female African giant rat. The uterus was identified as being duplex, having two separate uterine horns and two cervices. The two cervices were partially fused and separated by a mid-saggital septum. Their thick musculatures projected caudally into the vagina as the portio vaginalis uteri. The results also showed that eight mammary glands, distributed along the lateral aspects of thoracic and inguinal regions, were present. The thoracic and the inguinal regions had four mammary glands each and were arranged in two pairs of cranial and caudal rows. These findings fill some gaps created by the dearth of information on the reproductive biology of the female African giant rat.

Autores: Mehrdad,Jahanshahi; Bahadoran,H; Asadi,M. H.
Sulphur mustard (SM), commonly known as mustard gas is an alkylating agent that causes serious blisters upon contact with human skin. SM is frequently used as a chemical warfare agent. There is some evidence for sulfur mustard-induced lymph system effects in humans. Between 2000-2001, 42 male albino Wistar rats were used. After accommodation with environment, we divided rats to control, sham and experimental groups (2.5 mg/kg, 5 mg/kg, 10 mg/kg, 20 mg/kg and 40 mg/kg). Then we injected sulphur mustard oil in rat's intraperitoneal space. Then their spleens were removed for histological verification. Our results showed that significant difference in lymphocytes number in experimental groups after 24 hours. The number of lymphocytes in 5, 10, 20 and 40 mg/kg...

Variant Inferior Root of Ansa Cervicalis
Provedor de dados: 77
Autores: Babu,B. Prakash.
Ansa cervicalis is a loop of nerves found in the anterior wall of the carotid sheath in the carotid triangle of neck innervating infrahyoid muscles. Its superior root has fibres from the first cervical nerve that leaves the hypoglossal nerve and joins the inferior root formed by the branches from the second and third cervical nerves. The two roots join to form ansa cervicalis. The ansa cervicalis nerve formation is relatively complex, as its course and location along the great vessels of the neck vary. In the present case on the left side of an adult male cadaver the inferior root was absent and the contributions from C2 and C3 were joining independently with the superior root of ansa to form ansa cervicalis. However no such variation was found in the ansa...

Preservation of Haemal Nodes Fixed by Means of Two Different Aldehyde Fixatives: a Scanning Electron Microscopic Study
Provedor de dados: 77
Autores: Guerrero,F; Cerutti,P; Marcaccini,A.
Glutaraldehyde is the fixative most commonly used in electron microscope studies of biological tissues, however it is often necessary to use samples which were not fixed in this fixative, even with the usual uncertainty of the results that may be obtained. The fixation is the more delicate step of the sample processing. Therefore in this work, the quality of preservation of haemal nodes fixed with two classic aldehyde fixatives: formaldehyde and glutaraldehyde we have compared under the scanning electron microscope. Our results showed that both fixatives were successful in preserving the morphology of haemal nodes components; however glutaraldehyde conferred satisfactory results mainly in the preservation of parenchymal cells, whereas formaldehyde was...

Piriformis muscle syndrome has been increasingly recognized as a cause of leg pain. Overuse, strain, or anatomical variations of the relationship between the nerve and the piriformis muscle are thought to be the underlying causes of the entrapment of the sciatic nerve. We report a variation not previously described which was found during a routine dissection. During routine dissection of the left gluteal region of an adult male cadaver we observed a high division of the sciatic nerve and the presence of an accessory piriformis muscle. The sciatic nerve divided beneath the piriformis muscle and the common fibular nerve passed over the accessory piriformis muscle, whereas the tibial nerve reflected anteriorly to pass between the accessory piriformis and the...

Es también conocida como derivación porto-sistémica extra hepática congénita (CEPS), por su sigla en inglés, y se asocia a otras alteraciones congénitas,incluyendo anomalías cardíacas, de las vías biliares, enfermedades metabólicas y retardo mental. En este trabajo presentamos el hallazgo de esta malformación en el cadáver de un niño de dos años de edad, donde la vena porta seguía un trayecto anómalo y se unía a la vena renal derecha....

Most anatomical and biomechanical studies on the craniovertebral junction have involved morphological or morphometric analysis on the occipital condyles. Some of these studies have provided important findings based on different surgical procedures. The shape, size and angle of the occipital condyles and the locations of the intracranial and extracranial orifices of the hypoglossal canal are highly important because they may affect the lateral approaches to the craniovertebral junction. To determine the frequency of occurrence of different morphological types of occipital condyle. 214 occipital condyles in 107 dry human skulls were analyzed and the classification of their morphological types was determined through assessing digitized photographic images....

We suspect that morphological change of two types of aneurysms in ruptured and unruptured aneurysms are distinguishing because of different location and haemodynamics. So it is necessary to discuss sidewall and bifurcation type aneurysms in ruptured and unruptured state respectively. We used 209 consecutive aneurysms (144 ruptured, 65 bifurcation type) to assess the following parameters in 3D: maximum diameter (Dmax), maximum height (Hmax), aspect ratio (AR), size ratio (SR), height/width ratio (HW), bottleneck factor (BNF, width/neck) and inflow angle (IR). These aneurysms were divided into four groups by whether ruptured and sidewall or bifurcation. 4 groups were pairwise compared by univariate analysis and some parameters with significant variation were...

Estimation of age-at-death is an integral part of the identification process of individuals in many forensic odontology cases where their identity cannot be determined by visualization or other ways. Dental age estimation in the adult is more challenging as most of the dentition is completely developed by 18 years of age. This study employs a mesio-distal (MD) pulp-to-tooth ratio taken at the neck of lower third molars (LM3) to provide an estimation of age at the time of radiographic imaging based on the well-known fact that pulp volume tends to decrease with advancing age due to continued apposition of secondary dentine throughout adulthood. A total of 155 Cone-beam computed tomography (CBCT) radiographs of LM3s for a random sample of 155 Jordanian Arabs...

Autores: Yu,Ming-Yang; Zhang,Wei; Zhang,De-Bao; Zhang,Xiao-Dong; Gu,Gui-Shan.
Purpose: There is a paucity of data which reflected the relationship between morphology and incidence of shoulder disorders with respect to the ethnic Chinese population. We used anteroposterior radiographs to measure the Acromion Index (AI) and Acromioglenoid Angle (AA) of Chinese patients. The baseline was defined as the line that connected the superior and inferior osseous margins of the glenoid cavity. In order to calculate the AI, the distance from the baseline to the lateral margin of the acromion was measured and then divided by the distance from the baseline to the lateral aspect of the humeral head. The AA was defined as the angle formed by the intersecting line drawn tangent to the sclerotic line of the acromion undersurface and the baseline...

The Qualitative Effects of Resveratrol and Coenzyme Q10 Administration on the Gluteus Complex Muscle Morphology of SJL/J Mice with Dysferlinopathy
Provedor de dados: 77
Autores: van der Spuy,Wendy Jeannette; Pretorius,Etheresia.
Dysferlinopathy is a form of muscular dystrophy affecting muscles of the shoulder and pelvic girdles, resulting from inheritance of a mutated dysferlin gene. The encoded dysferlin protein is proposed to be involved in sarcolemmal vesicle fusion with a disrupted plasma membrane; however, with defective protein function these vesicles accumulate beneath the disruption site but are unable to fuse with it and reseal the membrane, thus rendering the membrane repair mechanism defective. The SJL/J mouse model presents with characteristics much like the commonest human condition. Immune modulators have long been under study in the maintenance of muscle health in muscular dystrophies. Such supplementary treatment would ideally suppress inflammation, preventing the...

Origin, Evolution and Homologies of the Weberian Apparatus: A New Insight
Provedor de dados: 77
Autores: Diogo,Rui.
The Weberian apparatus is essentially a mechanical device improving audition, consisting of a double chain of ossicles joining the air bladder to the inner ear. Despite being one of the most notable complex systems of teleost fishes and the subject of several comparative, developmental and functional studies, there is still much controversy concerning the origin, evolution and homologies of the structures forming this apparatus. In this paper I provide a new insight on these topics, which takes into account the results of recent works on comparative anatomy, paleontology, and ontogeny as well as of a recent extensive phylogenetic analysis including not only numerous otophysan and non-otophysan extant otocephalans but also ostariophysan fossils such as...

The abnormal origin, presence of additional head and layered arrangement of fibers are the reported variations of sternocleidomastoid muscle in the past. In the present case we report a rare unusual origin of third head of the sternocleidomastoid muscle in a 60 year-old male cadaver. This additional head originated from the investing layer of cervical fascia in the roof of the subclavian triangle close to the clavicle and traversed obliquely upward, forward and fused with clavicular head. The insertion and nerve supply of the muscle was found to be normal.

The aim of this study was to investigate the anatomy of the maxillary artery (MA) and its branches. Fourteen sides of Turkish adult cadavers were dissected. The specimens were classified according to the relation between MA and the lateral pterygoid. After the removal of the lateral pterygoid, parts and branches of MA were exposed. We classified the branching patterns of MA in the pterygopalatine fossa. The calibers and lengths of the arteries, and the distance between the zygomatic arch and MA, and between the infratemporal crest and MA were measured. The MA was found superficial to the lateral pterygoid in 57.2%. The inferior alveolar artery (IA) was arisen from MA before the middle meningeal artery (MM) in 35.7%, after MM in 35.7%. The IA and MM were...

Autores: Jaramillo,Priscilla C; Fuentes,Katterina; Cortés,Carla; Cisternas,Carlos; Salazar,Luis A.
El alcoholismo es un importante problema de salud pública. En los últimos años ha causado interés el metabolismo del alcohol, puesto que ha sido considerado un posible determinante biológico en la conducta de consumo. Variados estudios se han orientado a la búsqueda y comprensión de la influencia de polimorfismos, en genes que codifican para los principales sistemas enzimáticos que intervienen en el metabolismo hepático. El polimorfismo rs671 del gen que codifica la enzima ALDH2 ha sido asociado a un menor consumo de alcohol debido a la acumulación de acetaldehído en sangre. Diversos estudios indican que este polimorfismo es frecuente en países asiáticos y se considera un factor protector en los individuos que lo portan. Se incluyeron 207 individuos...

Autores: Meng,Shaoquan; Bei,Yongjian; Li,Guifen; Lu,Ronghui; Qi,Baomin; Wu,Defeng.
The gills of Ichthyophis bannanicus have yet to be investigated. This paper describes the external morphological features of the gills of mature I. bannanicus embryos exhibiting three pairs of gills on their neck region. Each gill is composed of an axis and filaments. In newly released embryos, the filaments and the axis form at approximately 90° relative to each other; eventually, this angle decreases and the color of the gill fades. The filaments on the axis are arranged alternately, and their spacing varies. The mid-pair of gills is significantly longer by nearly twofold than the front and rear pairs. Likewise, the lengths of the front and rear pairs of gills are not significantly different (P &amp;gt;0.05); for the same pair of gills, the lengths of...

La vasculogénesis es controlada por una serie de mecanismos que se activan en función del tiempo y del espacio durante el desarrollo embrionario. Múltiples son las vías de señalización implicadas en las etapas del proceso vasculogénico, las que se inician con estímulos angiogénicos desde el mesodermo o desde el endodermo para dar origen a los angioblastos (células progenitoras endoteliales). Proteínas como el factor de crecimiento vascular endotelial (VEGF), factor de crecimiento fibroblastico 2 (FGF2), entre otras, constituyen factores claves en la inducción de este proceso. Posteriormente, los angioblastos deben migrar para dar origen a los vasos primitivos, proceso en el que participan factores atrayentes y repulsivos que orientarán la dirección de su...

Diabetes is now considered one of the main threats to human health in the 21st century and many researchers are dedicated to investigate the physiopathology of the disease, with further insights on the managements of its major complications. Since understanding the pathophysiology of the major complications of diabetes and their underlying processes is mandatory, experimental models of the disease may be useful as they allow the recognition of the early mechanisms involved in the long-term complications of diabetes. Peripheral nerve involvement is highly frequent in diabetes mellitus and it has been documented that one third of diabetic patients have peripheral neuropathy. The true prevalence is not known and reports vary from 10% to 90% in diabetic...

Anatomical and Clinical Considerations of the Pectoralis Tertius Muscle in Man
Provedor de dados: 77
Autores: del Sol,Mariano; Vásquez,Bélgica.
The anatomical variation of the major pectoral muscles is infrequent, namely the agenesis of the pectoralis major muscle due to the morpho-functional alterations it causes. On the other hand, he presence of -supernumerary - pectoral muscles is not common and its physiological, clinical or surgical importance will depend on the stage of its development. The important aspect is that these muscles, while crossing the anterior wall of the axila and inserting in the humerus, may confuse or difficult surgical access to the content of the axillary fossa. Pectoralis tertius muscles were found in two dissected cadavers at the Topographic Anatomy of the Faculty of Medicine of the Universidad de La Frontera, Chile. These muscles were bilateral and independent of the...

Proximal Femoral Epiphysis Anatomy in Chilean Population: Orthopedic and Forensic Aspects
Provedor de dados: 77
Autores: Osorio,Horacio; Schorwer,Karl; Coronado,César; Delgado,Javier; Aravena,Pedro.
From a biomechanical standpoint, bone geometry and density are factors correlated to the bone resistance of the femur when supporting body weight, with geometric parameters like the diameter of the femoral head and neck, the length of the femoral neck, and the femoral neck angle as determinant factors in the incidence of hip fractures, which increase in frequency and seriousness in osteoporotic patients. In Chile, morphometric data that contributes to relating the anatomy of the proximal epiphysis of the femur as an associated factor in hip fractures does not exist; likewise, there are no anthropometric indexes that may contribute to the forensic sciences. The purpose of this study is to establish average measurements of the proximal epiphysis of the femur...

Provedor de dados: 77
Autores: Shetty,Surekha D; Nayak,Satheesha B; Kumar,Naveen; Somayaji,S. N; Rao,Mohandas K. G.
Occurrence of variant muscular slips from pectoralis major muscle is rare. In this report, we present a rare case of aberrant muscular slip associated with the pectoralis major muscle which we call costodorsalis. This muscular slip originated from the 6th rib near the costochondral junction and ran along the lower border of pectoralis major muscle. It crossed the axilla from medial to lateral side and merged with the latissimus dorsi muscle. This type of origin and insertion is unique and has not been reported earlier. The knowledge of this muscle variation may be of special importance to the anesthesiologists, physiotherapists and plastic surgeons.

Provedor de dados: 77
Autores: Trivedi,S; Athavale,S; Kotgiriwar,S.
Advanced imaging techniques have resulted in increasing use of minimally invasive approaches for nephron sparing surgeries of kidney. Need for precise knowledge of normal and variant anatomy of vascular pedicle of kidney is thus justified. Ample literature is available on the variations in the intrarenal vascular pattern of the kidney, which are seen frequently. But the variation in arrangement of structures at the renal hilum has not gained much interest up till now. One hundred (51 right and 49 left) embalmed kidneys were utilized for the present study. Careful dissection of renal hilar structures was carried out to observe antero-posterior relationship of structures at the hilum of the kidney. In majority (73%), the arrangement was not according to the...

Middle ears of adult Chaetophractus villosus, C. vellerosus and Zaedyus pichiy were studied for qualitative and quantitative comparisons. A great similarity in the overall shape of the middle ear structures was observed in the three species. The well-developed auditory bulla was formed by the intimate fusion of the tympanic and entotympanic. Internally, a recessus meatus and a wide epitympanic recess extending dorsally into an epitympanic sinus were recognized. The petrosal promontorium, nearly triangular, was the most salient feature in the tympanic cavity. The auditory ossicles corresponded to the transitional middle ear type. The m. tensor tympani and the m. stapedius were conspicuous. The lack of a stapedial artery was confirmed in all cases. The...

The large size of superficial group of muscles of back of leg is a characteristic feature of the musculature of man being related directly to its erect posture and mode of progression. Triceps surae is one of the powerful muscles of the body after Gluteus maximus and Quadriceps femoris. To make the muscle more powerful nature has devised a unique method of packing the fibers in a small space by pennation. There exists a bipenniform mass as a peculiarly human feature. Its feathered fasciculi arise from the deep (anterior) surface of the soleus muscle. Most of the textbooks of Anatomy and the available literature on the triceps surae or the tendoachillis do not appreciate and describe this fascinating aspect of the muscle. It was Schafer et al.

Interparietal Bone Variations in Accordance with their Ossification Centres in Human Skulls
Provedor de dados: 77
Autores: Khan,Aaijaz Ahmed; Ullah,Muzammil; Asari,Mohd. Asnizam; Hassan,Asma.
The upper interparietal segment of the squamous part of the occipital bone develops in membrane and the lower supraoccipital part develops in cartilage. According to the available literature, the interparietal segment is ossified from 2 to 3 pairs of ossification centres and each of these centres has 2 nuclei. Interparietal bone is formed due to failure of fusion of these centres and/or their nuclei with each other. Many variations of interparietal bone have been reported by many investigators. In the present study, out of 25 human skulls studied, six skulls had some interesting variations of interparietal bones.

Obesity has reached epidemic proportions, the World Health Organization (WHO) estimates that there are more than 1,000 million overweight adults world-wide. Furthermore, obesity is characterized as an overgrowth of white adipose tissue as a result of adipocyte hypertrophy and hyperplasia. Mitochondria is considered the source of energy within the adipocyte, since it contains the molecular machinery, and it is involved in a large number of metabolic pathways, besides the transformation of chemical energy into adenosine triphosphate. Mitochondria shortage and adipocyte dysfunction result in an excessive accumulation of triacylglycerol in the cytoplasm, which determines an imbalance between energy production and energy expenditure. Resveratrol (RSV) is a...

The description of the embryonic and larval development was based on 30 eggs and 30 larvae. Breeders were collected on the Usumacinta River, Tabasco, Mexico and were subjected to manual fertilization in May 2011. Fertilized eggs were spherical, pelagic, translucent and non-adhesive and had an average diameter of 1.07 mm (SD = 0.10), showing a concentric lipid droplet of 0.85 mm (SD = 0.02). The embryo occupied 100% of the perivitelline space at hour 14:08 post-fertilization and the egg measured 1.18 mm (SD = 0.14) at this stage. Eclosion started 17 hours post-fertilization when larvae had a length of 2.54 mm (SD = 0.66). Eight preanal and 13 postanal myomeres were observed exhibiting a light brown color. The morphologic characters recorded in this study...

Autores: Rai,Rajalakshmi; Ranade,Anu V; Prabhu,Latha V; Prakash,; Rajanigandha,V; Nayak,Soubhagya R.
Presence of additional muscles in the pectoral region has often been reported. We report about the presence of Pectoralis Minimus muscle, in a male cadaver. It was present deep to the pectoralis major muscle and superomedial to the pectoralis minor muscle. The variant was closely related to the branches of thoracoacromial vessels where one of the branches was passing between the pectoralis minor muscle and the variant muscle. Hyperabduction of the arm may compress these vessels giving rise to certain vascular symptoms. Also these variations should be borne in mind during certain surgical procedures in the pectoral region.

Provedor de dados: 77
Autores: Dave,Mitesh R; Yagain,Vaishali Kiran; Anadkat,Samir.
Pain is a common distressing symptom in dental practice. Depending upon the cases, different techniques are used to relieve pain. One of these is peripheral trigeminal nerve block. Peripheral trigeminal nerve block anaesthesia has proved to be an effective and convenient way to anaesthetise large regions of oral and maxillofacial complex. This block can be intraoral or extra oral. The intraoral route is through the greater palatine foramen in which the dental surgeons enter into the pterygopalatine fossa, where the maxillary nerve is situated. The morphological variations in the position of greater palatine foramen may be of clinical importance in the administration of local anaesthesia and in palatal surgery. In the present study, the distance of greater...

A New Quantitative Method for Predicting Forensic Racial Identity Based on Dental Morphological Trait Analysis
Provedor de dados: 77
Autores: Alsoleihat,Firas.
Few previous studies have demonstrated the likelihood of using the worldwide patterns of dental morphological variation in prediction of ancestry in the context of forensic dental anthropology. This paper introduces a new quantitative method for predicting forensic racial identity of individual specimens based on dental morphological trait analysis. In this study, the inter-population variation in the expression frequency of 16 non-metric tooth crown traits, manifested on the permanent dentition, was used for analysis. The method was developed from the notion that dental morphological characteristics, when viewed as sets of traits rather than isolated variables, can be utilized to calculate the relative probability that an individual belongs to a...

Autores: Flores Quintana,C; Blanco Cohene,T; Arbués,R; Domitrovic,H; González,J.
Durante el período reproductivo, en el ovario de los teleósteos se forman cíclicamente folículos primarios, los que maduran y son liberados en el momento de la ovulación. Sin embargo, algunos de ellos desarrollan un proceso de atresia con degeneración y reabsorción, el que para ser considerado un evento fisiológico debería predominar al final del ciclo reproductivo. Las características morfológicas de ovarios de Prochilodus lineatus fueron analizadas para identificar la presencia de folículos atrésicos como indicadores de posibles modificaciones de su biología reproductiva que afecte la repoblación de la especie. En los ovarios de P. lineatus predominaron los cambios morfológicos que se corresponden con la denominada atresia tipo I, y los folículos...

An unusual unilateral variation in the branching pattern of axillary artery was observed in a 60 year oíd female embalmed cadáver. The axillary artery had only two branches arising from its proximal (first) part and no branches from its remaining distal (second &amp;amp; third) parts. The branches are superior thoracic (usual) and another large collateral (unusual) branch. This collateral branch is the origin of several important arteries as the circumflex scapular, thoracodorsal, posterior circumflex humeral, thoraco-acromial and lateral thoracic arteries. We propose to ñame this artery as common subscapular trunk. The course of this collateral artery (common subscapular trunk) and its branches and also clinical significance of this variation are...

Problem based learning (PBL) made a great impact on the methodology of teaching. The major advantage of PBL method of teaching is integration of basic and clinical sciences in an integrated curriculum. This is achieved by presenting clinical problems to students which contain learning objectives from subjects related to the given clinical problems. In recent reports deficiencies have been reported regarding quantity of anatomy content of the clinical problems which has resulted in difficulty in understanding of theanatomy. We have made an attempt to quantify the content of anatomy and its sub-disciplines in PBL curriculum by a case study method using 'documentary analysis' at School of Medicine and Health Sciences, UCSI University, Kuala Lumpur, Malaysia....

Autores: Meruane,Manuel; Rojas,Mariana.
La Piel y sus estructuras asociadas permiten a los seres vivos subsistir en los diferentes ambientes ecológicos. El desarrollo de la piel y sus anexos en diferentes especies repite patrones comunes. De suma importancia es la interacción epitelio-mesénquima como regulador inicial de este desarrollo. El evento crucial en la formación de anexos, es la aparición de una placoda ectodérmica, a la cual se le asocia una condensación de células dérmicas, expresándose proteínas como Sonic Hedgehog (SHH) y la proteína morfogenética del hueso (BMP) para luego dar forma al anexo de cada especie. En esta revisión describiremos las etapas sucesivas que transcurren en la formación de la dermis, epidermis y anexos, con énfasis en las proteínas que dirigen el proceso.

The effects of experimental Trypanosoma congolense infection on the ejaculate of rabbits and changes caused after treatment with Diminaveto® were investigated using 24 New Zealand White rabbits (bucks). The bucks were housed singly in standard rabbit cages and fed on specialized ration containing 10% Protein supplement, grains, legume, salt and fresh water ad libitum during the study. Data on ejaculate characteristics were collected from all the bucks in the first phase (i.e. before infection) and in the second phase (i.e. during infection, with 4.8x10(5) Trypanosoma congolense, intraperitoneally). Similar data were collected from 12 randomly selected bucks treated with 7.0mg/kg Diminaveto® following reconstitution during the third phase. Data collected...

Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were confirmed. The horizontal line which extends between the most prominent point of the lateral and medial margins of patella was defined as a reference line. The distance of branching point of the GAs from the reference line was measured, and the correlations between these points were analyzed. The superior lateral and medial genicular arteries (SLGA and SMGA) were located at + 38.17 ± 3.10 mm and + 32.68 ± 3.83 mm from the reference line, respectively. The...

The main objective of this study was to obtain information on indicators of obesity among the unemployed male subjects from the Tuzla Canton. Also, we wanted to determine whether there are significant differences in the observed parameters between subjects in relation to age. The main criterion for the selection of test subjects is that they are unemployed. This is because we felt that those persons have more free time for practicing sports and recreational activities, and there is a very small number of studies in the area of Tuzla Canton with the characteristics of the sample. For the purpose of this research we applied analysis of percentage/ratio, t-test for independent samples and the Mann-Whitney U Test. Applied analysis showed that the increased...

Provedor de dados: 77
Autores: Mutua,P. M; Gicheru,M. M; Makanya,A. N; Kiama,S. G.
In mammals, surface respiratory macrophages (SM) are known to play a foremost role in protecting the respiratory system by providing first line of defense through engulfing pathogens and particulate matter respired with air. It has been reported that the pulmonary cellular defense system of domestic birds is inadequate. In particular, low number of SM and even lack of the cells in a healthy avian respiratory system have been associated with susceptibility of domestic birds to respiratory diseases. In an endeavor to resolve the existing controversy, the quantitative and qualitative attributes of the surface respiratory macrophages of the domestic duck and of the domestic rabbit were compared under similar experimental conditions. Quantitatively, the rabbit...

The neural plasticity showing the ability of nervous system to change its structure and function is a well-documented fact. However regional variation within a CNS structure to undergo plastic changes has been shown by limited studies. Along medial-lateral sequences of parasagittal sections, the molecular layer thickness of primary fissure borderlands in rat cerebellar left hemisphere was studied to assess the regional difference in plasticibility. Despite the homogeneity of cerebellar histology, this study showed that there is a significant interlobular difference between ML thicknesses of Prf borderlands. In addition, it revealed that the thickness alters in a significant trend within each borderland. The quantitative heterogeneity of cerebellar...

Autores: Ghosh,Susmita; Mandal,Lopamudra; Roy,Sanchita; Bandyopadhyay,Manimay.
Human anatomy is an ocean of unending variations and its mysteries are being unravelled since ages. Knowledge of variations in the superficial veins of head and neck is essential to carry out successful surgical procedures. During routine dissection of head and neck of two middle aged male cadavers, in the Department of Anatomy, Calcutta National Medical College, Kolkata, India, we came out with some interesting venous architecture. The retromandibular vein on the left side of both the cadavers was found to be undivided and joined with the facial vein in the neck at an acute angle to form a common venous trunk at variable distances from the angle of the mandible. That trunk ultimately drained into the left subclavian vein. This might be the result of...

Autores: Cortés-Delgado,Natalia; Pérez-Torres,Jairo; Hoyos,Julio Mario.
Transparency technique to demonstrate cartilage and skeleton has been used from years 70. This consists basically of the muscle digestion through an enzyme (trypsine), and the staining of cartilage and skeleton using alcian blue and alizarin red on specimens previously fixed to formalin. This technique can be used to study the state of the cartilage and the bones in different stages of the development and to observe abnormalitys. Also it can be used to demonstrate museum specimen skeleton preserved in liquid. In this article is showed the application of this technique for the first time in rodents and adult bats, besides some annotations to optimize the procedure.

Clinical and Functional Significance of Accessory Brachialis Muscle: An Unique Anatomical Variant
Provedor de dados: 77
Autores: Sirisinagandla,Sreenivasa Rao; Potu,Bhagath Kumar.
A thorough knowledge of the variations in the patterns of muscle insertion and the consequent neurovascular entrapment due to them is important for orthopedic and plastic surgeons. During routine dissection, we encountered a unique occurrence of an accessory brachialis muscle (acBr) blending with the medial aspect of bicipital aponeurosis in the cubital fossa. It also entrapped the median nerve and brachial artery due to its superficial position. The abnormality reported here might result in neurovascular compression symptoms in the upper limb and possible mechanical advantages or disadvantage in the flexion of elbow joint. To the best of our knowledge, the brachialis variant insertion we present here is rare in the list of its anomalies. We also discuss...

Autores: Cantín,Mario; Olate,Sergio; Fuentes,Ramón; Vásquez,Bélgica.
Alveolar ridge volume loss is an irreversible process. To prevent this physiological event, which typically result in significant local anatomical changes in both the horizontal and the vertical dimension, some strategies are indicated to minimize the loss of ridge volume that typically follows tooth extraction. The purpose of this study was to evaluate if three different bone grafts could promote new bone formation in the alveolar socket following tooth extraction for the alveolar ridge conservation. First mandibular molars of male adults rabbits were extracted and the extraction sockets were randomly treated with three different bone grafts, one xenograft and two alloplastic grafts, and a group that received no treatment (blood clot). The extraction...

Autores: Coriolano,M. G. W. S; Lins,O. G; Amorim,M. J. A. A. L; Amorim,A. A. Jr.
The anconeus is a small muscle situated at the elbow. Although the anconeus is active during elbow extension its importance for the movement is probably small. It could work as an elbow stabilizer. The object of this study was to investigate some anatomic and architectural characteristics of the anconeus, in the hope of shedding light on its function. We studied twenty adult cadaveric specimens. The anconeus originates by the lateral epicondyle of the humerus and inserts along the proximal ulna. The superficial shape of the anconeus is triangular. Tridimensionally the anconeus resembles a hemisected rectangular-based pyramid, with the base at the ulna and apex at the lateral epicondyle. The muscle fibers arise obliquely from the tendinous expansion and...

Autores: Costa,Jecilene Rosana; Prates,José Carlos; de Castilho,Helton Traber; Santos,Rafael de Almeida.
Knowing the anatomy of the nasal framework and its components, as well as their relations of size and shape is essential to correctly and safely perform nasal surgery, such as rhinoplasty. Symmetry and proportion of nasal bones and frontal processes of the maxilla related to patient's skull shape is not yet well established. Variation of these proportions due to differences in skull shape may interfere in the results of rhinoplasty, leading to poor aesthetic results and postoperative complications. This paper's objective is to measure and evaluate differences in shape and size of bony components of nasal framework (nasal bones and frontal process of maxilla) among different classes of skull shape. 121 skulls from UNIFESP-EPM Anatomy Museum, filed with...

Effects of graded dosages of methanolic extract of Aspilia Africana were examined on the estrous cycle, uterine weights and histology to determine its effects on the reproductive functions of 25 cyclic female rats. The rats were randomized into five groups A, B, C, D, and E. They were given Omg/kg body weight, 150 mg/kg body weight, 200 mg/kg body weight, 250 mg/kg body weight, and 300 mg/kg body weight, respectively. The effect on the estrous cycle was determined by vaginal lavage while routine histological preparations were done with haematoxylin-eosin stains. All values were statistically compared at appropriate confidence intervals. Estrous cycles were significantly reduced in a dose-dependent manner and histology revealed a dose-dependent toxicity

Autores: Wang,Jia-xiang; Li,Peng; Zhang,Xiao-ting; Ye,Li-xun.
Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, has been detected in the thymus of multiple vertebrates. However, little is known about its distribution in the thymus of the African ostrich. In this study, we evaluated the distribution and morphological characteristics of ghrelin-producing cells in the thymus of the African ostrich. Our results revealed that the thymus consists of a capsule and a parenchyma, which comprises the cortex and medulla. Compared to the cortex, the medulla had a fewer number of thymocytes and a greater number of epithelial cells. Additionally, three thymic corpuscles were identified. Ghrelin-immunopositive (ghrelin-ip) cells were detected both in the cortex and medulla of the African ostrich thymus,...

Type 2 diabetes mellitus (DM2) is the most common chronic metabolic disease, affecting approximately 6% of the adult population in the Western world. This condition is a major cause of cardiovascular disease, blindness, renal failure, and amputations, with increasing prevalence worldwide. The inuence of obesity on type 2 diabetes risk is determined by the degree of obesity and by body fat localization, with insulin resistance (IR) being the main link between these metabolic diseases. Experimental studies have shown that dietary factors, and particularly lipids, are strongly positively associated with body mass (BM) gain; IR; and, consequently, type 2 diabetes. Similarly, excessive consumption of energy-dense carbohydrate-rich foods can trigger the onset of...

Autores: Gil,Julio; Gimeno,Miguel; Laborda,Jesús; Nuviala,Javier.
The possibility of characterizing the proximal convoluted tubuli of the dog kidney by means of a unique and objective value, is an attractive idea in order to automate its recognition in anatomy and patology. For this, we obtained a fractal dimension of the proximal convoluted tubuli in the dog kidney by mean box-counting method. The fractal value we obtained is a flat dimension, and it is different than the line fractal dimension of the dog kidney arterial pattern, which was previously calculated by us (Gil et al., 2006). Thus, from optical microscopy images, we are able to obtain a single quantitative measure to discriminate these dog kidney components. This measures can use to automate its recognition. Fractal geometry provides many advantages when...

It is natural that there is close relationship between cranial capacity, and the size of brain. Several studies have estimated the cranial capacity which indirectly reflects the brain volume. This study was carried out on 366 (226 male and 140 female) healthy university students aged between 17-26 years old at Mugla University, Mugla, Turkey. By using linear dimensions of the head the mean cranial capacity and SD in males and females were 1411.64+118.9 cm³ and 1306.95+162.9 cm³, respectively. There was a significant difference between genders (p&lt;0.05). This investigation was showed the cranial capacity is larger in males than females. We also proposed a regression formula that could be used to predict the cranial capacity

Neuroleptic drugs such as haloperidol has side effects on extrapyramidal pathways. Tardive Dyskinesia is the most important complication. The most characteristic feature of this Tardive Dyskinesia is involuntary movements of mouth and face. In regard to this problem, the induction of gliosis and cell death in the nervous tissue are considered. In this study, adult Sprague-Dawley rats were used as experimental models. Rats were divided into control and experimental groups. The rats were kept in the animal house under standard conditions during experiments. The control rats were intraperitoneally treated with normal saline for 6 days. The experimental samples were treated for the same time with 2, 5 and 10 mg haloperidol. After the trial period, the rats...

The fibularis tertius muscle (FTM) in man has been developed over time to acquire subsequent bipedal gait. The FTM functions as a crucial contributor in dorsiflexion and eversion, postulated over the years as a stabilizer of the talocrural joint, avoiding forced investment and protecting the anterior talofibular ligament. The literature describes that FTM is absent in 10% of cases, with no data on Chilean population. A study of surface anatomy in 168 young subjects, 60% female and 40% male students at the Universidad de Talca, Chile, with a mean age of 20.6 ± 1.68 years, was conducted. The presence of FTM was identified following the implementation of a clinical assessment protocol that determines the presence of muscle on the basis of a progression called...

Some studies have shown that pinealectomized female rats present a large concentration of collagen fibers in the endometrium. The lack of light results in morphologic alterations in the uterine lamina propria and in the muscular layer, reducing thus the uterine weight. Therefore, this work aimed to analyze ultra-structurally the influence of melatonin in the remodeling of the collagen in the endometrium, in the estrus phase, in pinealectomized adult rats or submitted to lack of light. The experimental groups: I- sham-pinealectomized maintained in a clear/dark cycle 12/12 hours, during three months; II- pinealectomized rats maintained in a clear/dark cycle 12/12 hours, for three months; III- normal rats maintained in clear/dark cycle 12/12 hours for three...

El análisis de rasgos no métricos dentales ha logrado establecer relaciones biológicas de grupos humanos pasados y actuales con un alto valor taxonómico. Aunque Sudamérica ha sido objeto de un número considerable de investigaciones sobre poblamiento, migraciones y mestizaje, son relativamente pocos los estudios que han utilizado información de rasgos dentales para este fin, con las consiguiente ausencia de datos en amplias zonas geográficas. Se realizó una revisión sistemática de la literatura en MEDLINE, SciELO, REDALYC y LILACS, sin restricción de fecha de publicación. Se incluyeron artículos completos y disponibles primarios y secundarios en español, inglés y portugués donde se realice el análisis de rasgos morfológicos dentales en poblaciones...

Autores: Rodríguez-Niklitschek,Cynthia; Cantín,Mario; Oporto,V. G. H.
Within the procedures involved in a successful endodontic treatment is the working length (WL) determination. The root canal end must be detected accurately, and a precise control of the WL must be maintained. There are several methods to determine WL. Researchers have published the average teeth length (ATL) to the human permanent dentition. These measurements are used as an anatomical reference. If the WL is evaluated using a radiographic image, it is accepted as clinical success if the limit of the canal sealing is 1 mm coronal to the root apex. One method to determine WL is based in substract 1 mm to ATL. Another method widely used, assert to achieve a more precise WL determination, through the use of an electronic apex locator (AL). Nevertheless,...

Autores: Lalwani,Rekha; Rana,Kum Kum; Das,Srijit; Khan,Riyazul Qamar.
The external jugular vein, which traverses the sternocleidomastoid muscle superficially, is known to exhibit variations in its formation and course. There are less reports on the communication of the external and internal jugular vein. During routine cadaveric dissection, we detected an abnormal communication of the external jugular vein and the internal jugular vein, in a 45 year male cadaver. The knowledge of both normal and abnormal anatomy of the superficial veins of the neck may be important for clinicians performing catheterization and surgeons operating in the region of the neck. The presence of such anomalous communications may also be important for radiologists performing angiographic and sonographic studies

This study aimed to bring the trapezius muscle, knowledge of the locations where the accessory nerve branches enter the muscle belly to reach the motor endplates and find myofascial trigger points (MTPs). Although anatomoclinical correlations represent a major feature of MTP, no previous reports describing the distribution of the accessory nerve branches and their anatomical relationship with MTP are found in the literature. Both trapezius muscles from twelve adult cadavers were carefully dissected by the authors (anatomy professors and medical graduate students) to observe the exact point where the branches of the spinal accessory nerve entered the muscle belly. Dissection was performed through stratigraphic layers to preserve the motor innervation of the...

Autores: Squarcia,Silvia Margarita; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
The morphology and relative size of the tympanic bulla of three species of dasypodids from Argentina, Chaetophractus villosus, C. vellerosus and Zaedyus pichiy, were studied. The bulla was observed to be morphologically similar and evidently hypertrophied in the three species. The degree of hypertrophy was higher in C. vellerosus and C. villosus than in Z pichiy. By means of ANCOVA it was clear that, although C. villosus has a bigger skull than C. vellerosus, the relative size of their tympanic cavity was similar in both species. On the other hand, the skull of C. vellerosus and Z pichiy are of similar size but the bulla was relatively shorter in the later

Autores: Renfeng,Li; Xiangqin,Tian; Songlin,Qiao; Yanyan,Yang; Enmin,Zhou; Gaiping,Zhang.
Microfold (M) cells act as antigen-sampling sites for initiating antigen specific mucosal immune responses, but they may also provide a gateway for enteropathogen entry. In this study we demonstrated villous M cells by morphological and immunohistochemical methods to be present in the three regions of the small intestine from newborn piglets. Immunohistochemical analysis, using anti- cytokeratin 18 (CK18) primary antibodies, showed a gradually decreased density of M cells from the lower crypt epithelium to the upper villous epithelium. The proportion of villous M cells was greater in the ileum than in the duodenum or the mid-jejunum. Ultrastructural observation revealed that villous M cells were mainly columnar in shape in the duodenum and the mid-jejunum,...

The Asymmetry and Modularity of the Hyoid Bone
Provedor de dados: 77
Autores: Urbanová,Petra; Hejna,Petr; Zátopková,Lenka; Safr,Miroslav.
Morphological variation is a result of interplay among multiple intervening factors. For hyoid bones, the shape and size differences have been scarcely covered in the literature and in majority limited to studies of sexual dimorphism or age dependency. To our knowledge, the human hyoid bone, in complete opposite to other cranial bones, has not been fully utilized to address development questions in terms of asymmetry or modularity. In the present paper, we used landmark-based methods of geometric morphometrics and multivariate statistical approach to study human hyoid morphology represented by the hyoid body and greater horns in a sample of 211 fused and non-fused bones. Within a sample variation analysis, we showed that the hyoid bone is, by nature,...

Provedor de dados: 77
Autores: Beu,Celia C. L.; Orsi,Antonio M; Domeniconi,Raquel F; Novelli,Ethel L. B.
The concentration of total protein measured by photocolorimetric methodology and reported as units per 100 mg of tissue decreased from the initial segment to the cauda epididymidis of the Golden hamster, being significant the numeric difference observed between these two regions. This observation was related with an increased synthesis and secretion of proteins to the lumen in proximal segments of the epididymidis duct, mainly in initial segment, as proposed for other rodents. LDH activity was higher in initial segment and distal cauda than in the caput and corpus epididymidis, although no significant differences in mean values had been observed. The high LDH activity observed in initial segment and cauda epididymidis of hamster had been related to an...

Morphostructural Relationships and Productive Functionality of Sheep Breeds Used for Terminal Crossbreeding in Chile
Provedor de dados: 77
Autores: de la Barra,R; Martínez,M. E; Carvajal,A.
The body shape of an animal population determines ranges of biological functionality and productive use. In sheep, meat productivity is closely related with the body size of the animal. Some sheep breeds are used in terminal crossbreeding to give the lamb favorable dimensional characteristics, but it is necessary to go deeper on the study of the relationships between morphostructure and productive aptitude of these breeds, since discrepancies could be due to the environmental effects or the degree of differentiation between the original pool of different breeds and the local populations. The study aimed to evaluate the morphostructural characters in four sheep breeds in Chile and discuss their relationship with the productive functionality of the body...

Prediction of Stature According to Three Head Measurements
Provedor de dados: 77
Autores: Rexhepi,Agron M; Brestovci,Behlul.
Morphometry is a non-invasive method important to assess the size, proportions, and composition of the human body. Because the prediction is an important subject in almost all life sciences, the aim of this research was to find out the cephalofacial variables that may predict the body height. Three cephalofacial variables and the body height were measured on 288 adult male subjects of the Kosovo Albanian population, aged 18­35 years old. Using the procedures of regressive analysis we found that cephalofacial variables: head height, head circumferences, face height, significantly may predict body height, and in this way we derived the specific regression equation for estimation of the body height, based on these cephalofacial variables. The predicted body...

Autores: Carvallo,Pamela; Carvallo,Eugenia; Barbosa-da-Silva,Sandra; Mandarim-de-Lacerda,Carlos Alberto; del Sol,Mariano.
Uno de los endulzantes más comúnmente utilizado es la fructosa. La fructosa es directamente metabolizada en el hígado y se puede transformar en glucosa, posteriormente es almacenada como glicógeno constituyéndose en una fuente de energía para los hepatocitos. Todo el exceso de fructosa se convierte en lípidos ejerciendo un efecto tóxico sobre el hígado, similar al producido por el exceso de alcohol, pudiendo provocar hígado graso no alcohólico (NAFLD). El objetivo de esta revisión es reunir hallazgos recientes en relación al efecto de la ingesta de fructosa en altas concentraciones y su relación con el NAFLD.

Autores: Lerma-Cabrera,Jose Manuel; Carvajal,Francisca; Alcaraz-Iborra,Manuel; Sanchez-Amate,Maria del Carmen; de la Fuente,Leticia; Cubero,Inmaculada.
Binge alcohol drinking during adolescence has been associated with neurotoxicity and increased risk for the development of alcohol use disorders. There is evidence that acute and chronic ethanol administration alters c-fos expression, an indirect index of cellular activity, in different brain regions in adult rats. We evaluate here if a binge-like pattern of ethanol exposure during adolescence has a relevant impact on basal and/or ethanol-stimulated regional c-fos activity during adulthood. For that aim, Sprague-Dawley rats PND 25 were saline pre-treated, (SP group) or binge-ethanol pre-treated (BEP group) for two­consecutive days, at 48-h intervals, over a 14-day period (PND 25 to PND 38). At adult stage (PND 63) and following 25 ethanol-free days, we...

Provedor de dados: 77
Autores: Ortega-Martínez,Marta; de-la-Garza-González,Carlos; Ancer-Rodríguez,Jesús; Jaramillo-Rangel,Gilberto.
It is considered that healthy adult cartilage has little or no capacity for renewal, and that chondrocytes maintain a stable resting phenotype and resist proliferation and differentiation throughout life. Recently we found that cell turnover in lung cartilage is possible and that nestin-positive cells may have a role in it. In this paper, we report additional findings about chondrocyte renewal in lung cartilage. Lung specimens from CD1 mice at the age of 2, 6, 12, 18 or 24 months were fixed in 10% neutral-buffered formalin and paraffin-embedded. Nestin expression was examined by an immunohistochemical peroxidase-based method. We found nestin-positive cells inside of cartilage islets and cells in division very close from them. Our findings indicate that...

Currently there is a growing concern, in both population and governments, to identify the effects of substances commonly disposed of into rivers and lakes, on aquatic fauna and flora. Thus the objective of the present study was to verify effects of biodegradable detergents and water from an urban lake on gills and liver of two neotropical fish species of great economic importance, Astyanax altiparanae and Prochilodus lineatus. In order to do so, lipofuscin, also called the ageing pigment, was used as bioindicator. After one and five months of experiment both tissues accumulated this pigment. These data are discussed from physiological points of view, related with lipid peroxidation and mitochondrial damage.

Provedor de dados: 77
Autores: Didia,Blessing C; Jaja,Blessing N. R.
Normal values of the tibial slope are necessary for realignment of displaced fractures of the tibia crest, repair of cruciate ligaments and correction of knee deformities. True lateral radiographs of normal knees were obtained in 119 males and 93 female Nigerian subjects. The tibial slope was then measured according to the anterior tibial cortex method. Mean angle in sampled subjects was 12.3 ± 4.90 (range: 0-240). Sex differences were statistically insignificant (p&gt;0.05). This study provides reference values of tibial slope among indigenous adult Nigerians. It also highlights on the clinical relevance of the angle and the need to establish normal ranges in other African populations.

Autores: Chiapparrone,María L; Soto,Pedro; Catena,María.
Campylobacter fetus is extracellular bacteria of the genital tract of cattle. They cause infertility and abortion, but there is no documented information on the susceptibility of bovine sperm cells to this bacteria. The aim of this present work was to study the effects provoked by Campylobacter fetus subsp. venerealis when in interaction with bovine sperm cells. The bovine spermatozoa were obtained frozen bovine semen pooled from uninfected bulls, and were exposed to living campylobacter over different periods of time. Light microscopy and scanning electron microscopy first revealed a tropism, then a close proximity followed by tight adhesion between these two different cells. A decrease in the spermatozoa motility was observed. Motile bacteria were...

Autores: Souza,Mónica Rodrigues de; Watanabe,Ii-Sei; Azevedo,Luciane H; Tanji,Edgar Y.
In this work, we studied the effects of C0(2), Nd:YAG and diode lasers on the enamel and dentin of deciduous human teeth. After the irradiations, the samples were duly prepared and set up on metallic bases, covered with gold and examined in the scanning electron microscope. The results showed that the irradiation with the C0(2) mode locked laser with 1.0 W power caused melting and irregularities with small cavities on the surface of the enamel. The irradiated area on the dentin surface appeared circular and well delimited, containing blocks of dentin and cracks. By using the pulsed Nd:YAG laser with 1.0 W mean power and 10 Hz frequency, the enamel surface presented granules of molten enamel, with a typical melting look. The irradiated dentin surface...

Los Orígenes de la Sociedad de Anatomía Normal y Patológica de Chile
Provedor de dados: 77
Autores: Rodríguez Torres,Alberto; Cárdenas Valenzuela,Julio.
Desde los inicios, anatomistas y patólogos se unen en el año 1938 creando la Sociedad de Anatomía Normal y Patológica, con el fin de estimular sus investigaciones, buscar relacionarse tempranamente con morfólogos del resto de América y potenciar sus publicaciones en los Archivos Chilenos de Morfología. Es así como morfólogos chilenos provenientes de las principales Universidades del país participan por primera vez en Congresos y Jornadas tanto nacionales como internacionales. Quizás el trabajo en común con los cadáveres fue un punto fundamental en sus inicios, más el avance de los conocimientos en cada una de estas disciplinas y diferencias políticas posteriores serían dos hechos que explicarían que se separasen posteriormente en el año 1970. Sería por...

Compared Morphology of the Cephalic Musculature in Five Species of Genus Urotrygon (Chondrichthyes: Urolophidae)
Provedor de dados: 77
Autores: González Isáis,Mónica; Montes Domínguez,Héctor Marcos.
This work aims to describe the morphology of dorsal and ventral cephalic musculature in five species of genus Urotrygon. Muscular differences were observed, mainly in the development level. Muscles showing certain degree of variation in the dorsal region were the cucullaris and the ethmoideo-parethmoidalis. In ventral view, higher variation was observed. Muscles showing differences were the depressor rostri, the depressor hyomandibularis, the preorbitalis medial, the coracohioideus, and the depressor mandibularis. Urotrygon aspidurus was the species with the largest differences, as it has no mandibular depressor, and the rostral depressor is quite developed. The shape and arrangement of cephalic musculature in Urotrygon is similar to that reported for...

Course Pattern of the Muscular Branch of the Median Nerve in Sri Lankans Hand
Provedor de dados: 77
Autores: Senanayake,Kithsiri J; Salgado,Sujatha; Fernando,Ranil.
Transligamentous variant of the recurrent motor branch is having a higher risk of getting damage during both endoscopic and open carpal tunnel releases. The incidence of the transligamentous variant is about 7% to 80% world wide. This wide variation of the incidence could be due to the failure of identification of the distal edge of the flexor retinaculum from the obliquely oriented fascia that runs from the distal edge. We used two criteria to identify the distal edge; the abrupt change in the thickness of the flexor retinaculum and its colour change in cross section. The incidence of transligamentous variant is rare and the reported high incidence could be due to an error in identification of the distal edge of the flexor retinaculum as shown by Kosin...

Electron Microscopic Evaluation of the Secretory Mechanisms of Renin from Juxtaglomerular Cells
Provedor de dados: 77
Autores: Aktas,Ranan Gulhan; Karabay,Gulten; Taskinalp,Oguz; Kutlu,A. Kemal.
Although the structure and the functions of juxtaglomerular cells (JG) have been well defined, there is still a controversy about the secretory mechanisms of renin from these cells. It has been assumed that exocytosis is the main secretory mechanism in these cells in many studies, while others suggest that secretion occurs in a quite different way in these cells. There are several studies suggesting that diacrine secretion, which is very difficult to visualize, might be the other mechanism for secretion of renin. This study is an attempt to find the answers of these questions by identifying the fine structural features of the secretory granules in juxtaglomerular cells. Cyclosporin A (CyA) has been used in the current experimental study since it has...

Estudios experimentales demuestran que modificaciones medioambientales pueden producir alteraciones en el desarrollo normal de la corteza cerebral visual y sus conexiones. Por otra parte, es posible que en condiciones naturales, las especies animales hayan desarrollado adaptaciones genéticas a las distintas condiciones de luminosidad en que realizan su actividad. Recientemente, se han observado variaciones significativas en la densidad neuronal cortical del área 17 (área visual primaria), en roedores silvestres con diferentes períodos diarios de actividad y relación filogenética distante (Abrothrix olivaceus y Phyllotis darwini), pero aún no se ha determinado la naturaleza genética o plástica de dichas diferencias.

The jaw muscles are essential components in the stomatognatic system. Their complex architecture allows them to execute several motor tasks. One of the structural peculiarities is the presence of hybrid and neonatal fibers.We studied the differences of the fiber-type in masseter and temporalis muscles along the first to nineth decades in both genders. Seventy-four (74) samples were analyzed by immunohistochemistry. Slow and fast muscle fibers distribution was similar in both muscles in both genders. Hybrid fiber was observed in all decades, and its frequency decreased significantly (p&lt;0.001) with aging in masseter. Neonatal myosin expression was observed in all decades, its expression was more frequent in masseter (p=0.01), and males in temporalis...

Provedor de dados: 77
Autores: Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da.
Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.

The apoptosis phenomenon happens in normal tissues and in many pathological conditions as described by several researchers. Most studied in the 70s, this phenomenon remained almost forgotten in the 90s, when, with the advent of more advanced techniques, returned to laboratories. Thus, electronic microscopy, Comet Assays and histochemistry techniques, among others, were utilized in an effort to elucidate in a thorough way, the mechanisms that lead the cell to "suicide". No one can deny the importance of the knowledge of such phenomenon, so as to control its induction or blocking in the treatment of pathologies such as cancer. In this work, the apoptosis study was aimed at denervated muscles in different periods. Furthermore, two types of skeletal striated...

Autores: Squarcia,Silvia Margarita; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
The morphology and morphometry of the cranial bones of Chaetophractus villosus were studied. The skull components are morphologically similar between adults of both sexes, and follow the generalized pattern for most of described dasypodids. The morphometric analysis, however, demonstrated that the bones lying in the rostrocaudal plane are mostly longest in females, determining higher values of the total, basal and condilobasal lengths of the skull, which are the main variables that contribute to a sexual dimorphism in this species

Many researchers have advocated in recent times that antiseptic use in healing wounds should be discouraged. Antiseptics have been found to retard healing of wounds. Innocuous solutions like normal saline and tap water are being considered as better alternatives to antiseptics. Chlorhexidine, a commonly used antiseptic, is known to be less toxic on granulation cells. We decided to compare the effect of chlorhexidine, normal saline and tap water on healing wounds. Three groups of wistar rats had 2 by 2cm full thickness wounds made on their right dorsolateral flanks. The wounds were dressed with either chlorhexidine, normal saline or tap water. Wounds were examined at three-day intervals and measurements of area covered were taken on the first day of study...

Variations in the branches of the abdominal aorta were determined during a routine abdominal region dissection of a 70-year-old male cadaver. Left gastric artery arose as the first root from antero-lateral of aorta. Coeliacomesenteric trunk occurred as a thick root. After 29.9mm, coeliacomesenteric trunk bifurcated as coeliac trunk and superior mesenteric artery. Coeliac trunk bifurcated as splenic artery and common hepatic artery. These multiple variations which change the normal anatomic structure of the abdominal aorta have to be kept in mind by surgeons, radiologists and anatomists.

Autores: Valdivia Gandur,Iván; Tallón Walton,Victoria; Carvalho Lobato,Patricia; Lozano de Luaces,Vicente; Manzanares Céspedes,María Cristina.
The relationship between sensitive innervation and normal mandibular bone development has been described in the literature. Therefore, neural damage is a potential cause of osseous deformities, particularly in growing subjects. The aim of this project is to present the mandible measurements obtained after the transection of the inferior alveolar nerve of growing rabbits. A specific surgical protocol was designed to carry out the unilateral nerve transection by avoiding musculoskeletal injuries. Twenty New Zealand White rabbits one week post-weaning were used, 12 as an experimental group and 8 as a control group (Sham operated). The animals were sacrificed 90 days postoperatory, and the mandibles carefully dissected. Dental midline deviation data were...

Autores: Vilaça Júnior,Paulo Estevao Araújo; Teixeira,Alvaro Aguiar Coelho; Wanderley Teixeira,Valéria; Moraes,Eleonora de Figueiredo; Araújo,Ana Claudia Carvalho de; Maia,Carina Scanoni.
The glucocorticoid dexamethasone has been largely used due to its anti-inflammatory effect. However, several authors report that the excessive exposition to it during pregnancy may cause a retard in the development in several tissues, mainly: liver, lungs and kidneys. But, the majority of the works are done with the application of dexamethasone in the late periods of pregnancy. Because of the lack of researches that evalúate the effects in the beginning of gestation, this paper aimed at evaluating the effect of dexamethasone administered in the initial phase of pregnancy, o ver the morphology of neonates rat. It was used 10 albino rats (Rattus norvegicus albinus) aged 90 days from the lineage Wistar. The female were coupled and divided in two groups: Group...

Anatomical Study of the Digastric Muscle: Variations in the Anterior Belly
Provedor de dados: 77
Autores: Liquidate,Bianca Maria; Barros,Mirna Duarte; Alves,Adriana Leal; Pereira,Celina Siqueira Barbosa.
The digastric muscle is formed by two muscle bellies: one anterior and one posterior, joined by an intermediate tendon. It is localized in the anterior cervical region. The anterior belly divides the region between the hyoid bone and the mandible into two: laterally the submandibular triangle, and medially the submental triangle. The anatomical variations described in the literature relate to the anterior belly and consist of differences in shape and muscle attachment. This cross-sectional cohort study had the objective of describing anatomical variations in the anterior belly of the digastric muscle. The neck regions of 10 cadavers of male adults were dissected in the Department of Morphology, between June 2004 and June 2006. The digastric muscles that...

Autores: Suazo Galdames,Iván; Zavando M,Daniela; Russo,Priscila; Smith,Ricardo Luiz.
This article analyzes the performance of diagnostic tests for sex determination by examining human skulls, using the Baudoin condylar index. For this study, 215 skulls were examined, and the maximum dimensions (length and width) of the right and left occipital condyles, were noted. With these data, we calculated the Baudoin condylar index and determined the level of agreement between the values for the left and the right side, the sensitivity of the method, the accuracy of the tests and the positive predictive value for each sex. The level of agreement in the diagnosis based on both sides was 65.58% (of which 83.09% were of women, and 63.88% were of men). The overall accuracy was 41.39%, and a greater sensitivity was seen in women (52.1% right side and...

Autores: Yeri,Luis Andrés; Houghton,Eduardo Javier; Palmieri,Bruno; Flores,María; Gergely,Marcelo; Gómez,Jorge E.
The cephalic vein shows a scarce description, especially in the deltopectoral triangle, and its ending in the axillary vein. Some established considerations such as "superficial vein, located in the deltopectoral groove, accompanied by braches of the thoraco-acromial artery, which ends in the deltopectoral triangle in the shape of fan arch" should be reevaluated. Procedures difficulties in the la catheterization deserve for a more accurate description. A descriptive, prospective study is performed. The goal is to determine the anatomy of the cephalic vein in the deltopectoral triangle, with a special focus on the characteristics concerning its path and type of termination. Findings show that the cephalic vein is deeply placed and has a different path than...

Autores: Nguyen,A.K.D; Simard-Meilleur,A. A; Berthiaume,C; Godbout,R; Mottron,L.
Macrocephaly has been reported as one of the few physiological markers of several syndromes which are identified during childhood. However, only a limited number of studies have investigated whether macrocephaly persists in adults in these conditions, due to an absence of up-to-date reference charts constructed for typically developing adults. Available adult head circumference reference charts either don't measure individuals beyond 21 years of age, are outdated, mostly use homogeneous samples and most importantly do not account for the individual's height and weight at the same time. Two hundred twenty-one male adults were recruited in a large urban community. For each participant, height, weight and head circumference were measured. A significant...

There is a dearth of knowledge on the level of agreement between all the various assessment tasks on the same content area, in order to test this hypothesis we adopted the concept of convergent validity and also to isolate area of academic weakness among the students and to readjust the curriculum content to balance the weakness. A blinded cohort retrospective study was carried out on a total of sixty-six third year medical students who had sat for their first professional examination in anatomy in the new medical college of Lagos State University. Using records of their grades in the various assessments parameters- the average end-in course assessment, short essays question (SEQ), multiple-choice questions (MCQ), and practical (Steeple-chase). The mean +...

Lymphatic Drainage of the Breast: from Theory to Surgical Practice
Provedor de dados: 77
Autores: Fregnani,José Humberto Tavares Guerreiro; Macéa,José Rafael.
Until recently, complete removal of axillary lymph nodes was performed as part of the treatment of breast cancer. Sentinel lymph node biopsy (SLNB) in selected cases has reduced the number of cases of wide axillary dissection and the related morbidity. Knowledge of breast lymphatic drainage is essential for understanding the principles behind SLNB and also for performing safe and correct axillary lymphonodectomy. This paper describes in detail the anatomical issues relating to breast lymphatic drainage and the correlated axillary and extra-axillary lymph nodes. In addition, it shows the application of this theoretical knowledge to surgical practice, especially with regard to SLNB and lymphonodectomy. The surgical nomenclature is compared with the current...

The radial nerve is a terminal branch of the brachial plexus that innervates the entire posterior compartment of the upper limb. Researches have shown that the branches can contribute to innervation of the muscles from the anterior compartment of the arm. This study sought to identify branches of radial nerve for brachialis and coracobrachialis muscles and its clinical value during surgery. Dissection was performed in 60 arms, from 30 corpses selected from the Human Anatomy Laboratories of Universidade Estadual de Ciências da Saúde de Alagoas (UNCISAL). In each arm, three segments of the same proportion were considered (proximal, middle and distal) in order to observe the number of radial nerve branches to brachialis and coracobrachialis muscles. Branches...

Handmade anatomy models may be a complementary useful tool to dissection and prosection, since the student interacts with the body structure in a three-dimensional way. In this study homemade dough (biscuit) was used to create a brain model. Two anatomy trainees from the medical school of the Universidade Federal Fluminense (Niteroi Brazil) were challenged to model the gross anatomy of the lateral aspect of the brain. They prepared and handled homemade dough to produce a simple and low cost model of the cerebral hemisphere. Styrofoam balls fixed by pins were used to create a framework, and dough rolls were modeled in order to create the brain sulci and gyri. At the end, the model closely resembled three-dimensional features of the human brain. Also, brain...

Provedor de dados: 77
Autores: Okamoto,Keishi; Wakebe,Tetsuaki; Saiki,Kazunobu; Manabe,Yoshitaka; Tsurumoto,Toshiyuki.
During dissection practice for medical students at Nagasaki University, a horizontal fissure and hypoplastic middle lobe were encountered in the right lung of an 81-year-old Japanese female. In a normal right lung, the horizontal fissure is situated anterior to the oblique fissure. On the contrary, in the present case, the horizontal fissure was situated posterior to the oblique fissure. We identified a small, additional lobe on the medial surface of this lung. It was situated in the medial part of the oblique fissure, and was determined to be a small hypoplastic middle lobe. As a result of the hypoplasia of the middle lobe, the original horizontal fissure may have disappeared from the anterior surface. The horizontal fissure, in this case, may be a...

Autores: Codón,Stella Maris; Casanave,Emma Beatriz.
The morphological features of the oviduct in the armadillo Chaetophractus villosus (Desmarest, 1804) were studied. In the simple columnar epithelium, ciliated cells, secretory cells, and cells of the bottom of the folds are described. The most remarkable findings are the increase in number of ciliated cells, when present, from the fimbriae to the uterus, being the isthmus practically lined by ciliated cells, and that secretory cells are more abundant in the apical zone of the ampulla and fimbriae, than in the isthmus. Morphological changes along the year in the different portions are described.

Ethanol Intake and Toxicity: In Search of New Treatments
Provedor de dados: 77
Autores: Sandoval,Cristian; Vásquez,Bélgica; Mandarim-de-Lacerda,Carlos; del Sol,Mariano.
Prolonged alcohol consumption has consequences on the liver, producing necrotic precipitates and fibrosis, on the pancreas, causing the pancreatic acini to atrophy and destroying insulin-producing cells, and on the central nervous system (CNS), causing the gray and white matter in the frontal lobes of the brain and cerebellum to atrophy. Generally, alcohol is metabolized via oxidative pathways, where the enzymes alcohol dehydrogenase and aldehyde dehydrogenase participate during its metabolization in the liver and CNS, or via non-oxidative pathways during its metabolization in the pancreas. Ethanol metabolism can produce oxidative stress and tissue damage mediated by free radicals, causing morphological and functional alterations in the liver. In the...

In the current carcinogenesis models, the occurrence of increasing mutations and selection mechanisms favoring cell survival and higher proliferation rates are taken into account. Epigenetic mechanisms, among which DNA methylation stands out, also take part in oncogenesis. The characteristic of tumor cells that allows the increase of mutations is named genetic instability, encompassing two mechanisms: microsatellite instability, characterized by nucleotide alterations with errors in the DNA repair systems; and chromosomal instability, represented by aberrations occurring in large chromosome segments. Carcinomas are characterized by complex cytogenetic alterations and large gene amalgamations. Telomeric alterations, inadequately repaired DNA breaks, and...

Morfógenos Durante el Desarrollo Embrionario de Vertebrados
Provedor de dados: 77
Autores: Rojas,Mariana; Signore,Iskra A; Mejías,Roberto.
Durante el desarrollo embrionario, las células de muchos tejidos se diferencian de acuerdo con la información de posición que se establece por las gradientes de concentración de morfógenos. Estas son moléculas de señalización secretadas en una región restringida de un tejido y se difunden lejos de su fuente para formar una gradiente de concentración. La molécula de un mismo morfógeno actúa generalmente en distintas etapas de desarrollo de un organismo y puede provocar reacciones muy diferentes en las células en función de su historia de diferenciación. Los morfógenos más conocidos son miembros del factor de crecimiento beta (TGF-b), Hedgehog (Hh), familias Wnt y los microRNAs.

El género Profundulus es uno de los grupos de peces más antiguos, distribuidos al norte de América Central en México, Guatemala y Honduras. No obstante, son pocos los trabajos que se han realizado para conocer el número de especies que lo conforman y sus relaciones filogenéticas. Históricamente se reconoció que este taxón estaba conformado por dos grupos naturales, actualmente considerados como los subgéneros Profundulus y Tlaloc. Recientes investigaciones genéticas han revelado un alto grado de diferenciación entre ambos taxones y algunas de sus especies, lo cual probablemente este asociado a cambios morfológicos.

This study compares the morphology of rostrum, pereipods 1,2,4 and mouthparts of juvenile Astacus leptodactylus with those oí Pacifastacus leniusculus. Differences in morphology were observed, in particular with regard to the mouthparts e.g. including setal armature and number of teeth on the mandible. In general, the shape of the rostra in the two species is similar in that both taper to a point with a pair of sharp spines distally. Laterally the rostrum of A. leptodactylus is bordered by a regular row of setae, which is not so well defined in P leniusculus. The observations also showed that in addition to an increase in size, changes in morphology in the feeding apparatus between the developmental stages of the two species were present.

Autores: Alfaro,; Figueroa Perez,Daniela; Sabat K,Pablo; Sallaberry,Michel; Canals L,Mauricio.
We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove (Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia melanoptera), two larger species. As expected, Columbina picui BMR and VO2max showed higher values than those of the larger species according to the expected for their body size. The respiratory surface density and the thickness of the blood-air barrier were not different among the different species of doves. However C. picui showed an anatomical diffusion factor lower than M. melanoptera and Z. auriculata. Picui Ground Dove had low values of oxygen diffusion capacity, such as cursorial birds. A differential oxygen partial pressure of...

Considering the size of some nuclei and area, sex hormones control the sexual development of the brain. The sexual development of the brain can also be influenced by environmental stress. This study aimed to clear the effect of prenatal water deprivation on the development of sexual dimorphic nucleus (SDN) of the brain. In this research, pregnant rats were divided into two groups (control and treated). For the treated animals, water was removed from the ewes for 48 h at the end of third trimester of gestation (19-21 days). TUNEL staining was used for detection of apoptosis in paraffin embedded diencephalon selected sections. The ratio of apoptotic cells to non- apoptotic ones was calculated as apoptotic index. Differences of apoptotic index and serum...

Provedor de dados: 77
Autores: Cortés,Manuel E; Hauyón,Roberto; González,Fernando; Vigil,Pilar.
Fractality has emerged as a feature of the organization of some complex natural systems. Several biological secretions show fractal-like patterns for their crystallization phenomena but their presence in crystallizations of bovine cervical mucus (BCM) is yet unknown. In order to assess the fractality of BCM crystallization, samples of this fluid were taken from heifers at oestrus, their crystalline patterns photographed and its morphology analyzed. Among the many images obtained for BCM crystallizations, one of them had a highly symmetrical geometric arrangement, possessing three zones characterized by pine-like, arboriform structures, evidencing a remarkable similarity between them. Moreover, fractal dimensions obtained for these zones were statistically...

Anomalous Lobar Pattern of Right Lung: A Case Report
Provedor de dados: 77
Autores: Modgil,Vishal; Das,Srijit; Suri,Rajesh.
The right lung classically has two fissures, an oblique and a horizontal, dividing it into three lobes namely the superior, middle and lower. The anomaly of the lobar pattern has been described by many research workers on CT scans, where as, there are fewer studies on gross anatomical specimens. In the present case , which was incidentally detected, we report three fissures dividing the right lung into four lobes. Such abnormal fissures and lobes are clinically important for identifying broncho-pulmonary segments. Anatomical knowledge of anomalies of fissures and lobes of lungs may be important for surgeons performing lobectomies, radiologists interpreting X ray and CT scans and also of academic interest to all medical personnel

Autores: Bruner,Emiliano; Costantini,David.
The morphology of cephalic scales in Lacertids is organised in well defined geometrical structures. The variation of these elements is related to the underlying bone growth and morphogenesis, but it is also associated with the muscular system and the sutural dynamics. In this paper, the patterns of variation of the cephalic scales have been compared between three common Mediterranean species: Podarcis muralis, Podarcis sicula and Lacerta bilineata. The morphospace generated by the morphological relationships within the cephalic system in these three species is investigated in order to consider their degree of variation and their anatomical peculiarities. Generally, Lacerta is 64% larger than Podarcis, shows a relative reduction of the frontal scale,...

Effects of protein and B-complex vitamin deficiency were assessed with respect to the morphometry of myenteric neurons in the descending colon of adult rats. Sixteen animals were divided into two groups: Control Group (CG, n=8) and Experimental Group (EG, n=8). The CG received 22% protein chow and the EG received 4% protein chow for 120 days. The descending colon was submitted to NADH- and NADPH-diaphorase technique in order to evidence nervous cells in the whole mounts preparations. In the EG, NADH-d positive neurons presented reduced nuclei, while NADPH-d positive neurons showed atrophy of the soma area (~41.7%) inducing an increase of the proportion occupied by the nucleus inside in the soma of these cells.

Back to the Debate: Sternalis Muscle
Provedor de dados: 77
Autores: Hung,Laurie Y; Lucaciu,Octavian C; Wong,Jessica J.
The sternalis muscle (SM) is an anatomical variant found in the anterior thoracic wall. While the attachment sites of SM are generally agreed upon, the innervation and function of this muscle are not well established. Cadaveric and surgical explorations to date report that SM is innervated by either the pectoral nerves or the anterior branches of the intercostal nerves, or a combination of both. Knowledge of SM is relevant to health care providers specialising in imaging and/or surgery of the anterior thoracic wall. This paper aims to raise awareness in the medical community of the clinical relevance of SM through two case reports and a brief literature review.

De Músculo Omohioideo a Músculo Escapulohioideo
Provedor de dados: 77
Autores: Ottone,Nicolás Ernesto; Vargas,Claudia Andrea; del Sol,Mariano.
Terminologia Anatomica se encuentra bajo constante revisión. A pesar de esto, continúan existiendo confusiones sobre el término correcto a utilizar pada cada estructura, en particular en español, ya que no existe una traducción oficial de Terminologia Anatomica en este idioma. Es conocido que el hueso antes llamado "omóplato" pasó a denominarse "escápula" pero aún no es oficial el cambio de nombre del músculo omohioideo, lo que se contrapone a una de las recomendaciones del Comité Federativo Internacional de Terminología anatómica que el término debe adaptarse al idioma vernáculo y su denominación debe concentrar la información y el papel descriptivo de la estructura en cuestión. Es por esto que hacemos un breve análisis del término M. omohyoideus...

Discriminación de Sexo en una Población Medieval del Sur de la Península Ibérica Mediante el Uso de Variables Simples
Provedor de dados: 77
Autores: Jiménez-Arenas,Juan Manuel.
Las asignaciones de sexo a los restos osteológicos es fundamental puesto que suponen el primer paso hacia el establecimiento de otros tipos de inferencias biológicas y culturales. Aunque la determinación del sexo es relativamente fácil cuando se recuperan determinadas partes esqueléticas, especialmente la pelvis y el cráneo, resulta más problemática a partir de otros huesos, sobre todo si se trata de fragmentos. En este trabajo se presenta un estudio de discriminación del sexo de los individuos a partir del húmero utilizando variables simples. Los resultados muestran cómo, utilizando la prueba de Lubischew, cada una de las principales partes del húmero aporta, al menos, una variable con porcentajes de discriminación cercanos al 90%. Estos resultados se...

Instrumentation of anterior vertebral body screws has become an important approach for treatment of unstable fracture or curvature of the spine, but little attention has been paid to the starting point of placing the screws and variability of the rib head position. We analyzed the variability of rib head position in a Chinese population in terms of the spinal canal and vertebral body using computed tomography (CT). Images from transverse CT scan of the T4-T12 vertebral bodies of 30 normal individuals were 3D reconstructed, and analyzed for measurement of parameters, which included: 1) distance between the left (or right) anterior border of the rib head and the posterior (or anterior) margin of the vertebral body [L(R )ARHP(A)VB], 2) left (or right)...

Provedor de dados: 77
Autores: Zhang,Yong; Yang,Shengbo; Yang,Fangjiu; Xie,Peng.
Variations in the brachial plexus and the distribution patterns of its branches are not uncommon. A communicating branch, which is the most frequent variation, often arises from musculocutaneous nerve to median nerve. However, the branches arising from lateral cord of the brachial plexus and median nerve instead of musculocutaneous nerve are very rare. Detailed description of the abnormalities is important for surgical procedures. Our case study reports the musculocutaneous nerve was absent, a branch from the medial cord innervated the coracobrachialis muscle and two branches from the median nerve innervated the biceps and brachialis muscles, respectively. Moreover, the median nerve gave off the lateral antebrachial cutaneous nerve. This report provides...

: Cuando se determina la asimetría de una estructura bilateral formada por subregiones asimétricas con lateralidades opuestas, queda enmascarada (compensada), total o parcialmente, la existencia de las diferencias interhemisféricas de tales subregiones. Para cuantificar esta realidad, hemos establecido un nuevo parámetro: la compensación. El objetivo del presente trabajo, realizado en cerebros humanos postmortem, está dirigido a determinar los porcentajes de compensación, de asimetría de peso y de superficie cortical, de tres regiones cerebrales pertenecientes al lóbulo frontal: 1. El área de motora del lenguaje (de Broca). 2. La porción anterior del giro frontal inferior. 3. El giro frontal inferior en su totalidad. Para valores de peso y de superficie...

Autores: Igbokwe,Casmir Onwuaso; Ezeasor,Daniel Nwagbo; Umar,Mohammed Bello.
The present study examined ultrastructure of the thyroid gland of adult West African Dwarf (WAD) goat in order to further understand the ultrastructural morphology and some of the changes in the components of the thyroid gland in goat with age. Thyroids glands obtained from fifteen adult WAD goats of different ages and sexes slaughtered at the local abattoirs were used in this study. Electron microscopic techniques were used to study the fixed tissue with emphasis on the follicular and parafollicular cells. The results showed that the ultrastructure is generally similar to that of some domestic animals. Follicular cells were cuboidal in young adult goats thyroids but were flattened in older goat thyroids of 5­7 years. These cells remarkably showed highly...

Provedor de dados: 77
Autores: Eghbal,Mohammad Ali; Taziki,Shohreh; Sattari,Mohammad Reza.
Carbamazepine is widely used in a broad spectrum of psychiatric and neurological disorders. Idiosyncratic hepatotoxicity is a well-known adverse reaction associated with carbamazepine. Hepatotoxicity is rare, but a real concern when initiating therapy. It was found that oxidative stress is a potential mechanism for carbamazepine-induced hepatotoxicity. Present study evaluated the hepato protective role of taurine and melatonin against carbamazepine-induced hepatotoxicity. Hepatocytes were prepared by the method of collagenase enzyme perfusion via portal vein. Cells were treated with 400 µM carbamazepine, 1mM taurine, and 1mM melatonin. Cell death, reactive oxygen species formation, lipid peroxidation, and mitochondrial membrane depolarization were assessed...

Androgenic anabolic steroids (AAS) are artificial testosterone analogues, used as medicine in chronic diseases, because they increase protein synthesis generating muscle hypertrophy. Its effect has caught the attention of athletes and gym users, thus their consumption has become epidemic, due to easy marketing, the immediate results and the false impression that it doesn't carry health risks. Such risks may globally harm the body. This study aims to investigate the influence on spermatogenesis of using nandrolone decanoate with or without physical training. Twenty-four rats, divided into four groups were used: sedentary group (SG), sedentary on steroids group (SSG), trained group (TG) and trained on steroids group (TSG). The animals were trained on...

The popliteal artery is located deep inside the popliteal fossa, and is an important landmark in surgical procedures. Lesions of this vessel and its branches can be dangerous, blocking circulation to the lower limb and leading to gangrene or even vascular failure. The aim of this work was to describe the biometric characteristics of the bifurcations of the popliteal artery and the tibiofibular trunk in relation to the head of the fibula in 38 lower limbs through dissection. The bifurcation of the both arteries was present in all the cases. The mean confidence interval for the bifurcation of the popliteal artery was from 2.82 cm to 3.18 cm from the head of the fibula, and that of the bifurcation of the tibiofibular trunk was from 5.72 cm to 6.68 cm.

El cáncer colorrectal (CCR) constituye el segundo tipo de cáncer más frecuente en la población europea. Actualmente no existe biomarcadores moleculares que se pueden utilizar para la detección temprana del cáncer de CCR. KLF6 es un supresor tumoral relacionado con varios tipos de cánceres. Nuestra hipótesis plantea que KLF6 puede ser un excelente marcador en el diagnóstico precoz de CCR. Para estudiar la implicancia de KLF6 en el CCR, se seleccionaron 15 biopsias de cada estadio (T1,T2 y T3) de los archivos del Servicio de Anatomía Patológica del Hospital Central de la Defensa Gómez-Ulla, las cuales presentaban áreas de tejido afectado (tumor) y áreas sin afectación (no tumorales).

Spodoptera frugiperda is a polyphagous insect that causes economic losses to several crops in Brazil and is the major obstacle to corn production. Researches focusing on alternative control, e.g. botanical products are expanding to offer a wide variety of molecules that interfere with different biological parameters of insect pests. Thus, this study tested the hypothesis that clove essential oil affects the spermatogenesis, ovarioles histochemistry and the fertility of S. frugiperda. The results showed that clove essential oil affects the gametogenesis of S. frugiperda ovarioles, reflecting negatively on its reproduction, proving to be a promising tool for controlling this pest.

El análisis seminal o espermiograma es uno de los parámetros más usados en la evaluación de la fertilidad masculina. La OMS (WHO, 2010), presentó el 5 Manual para el examen y procesamiento del semen humano, documento que fue analizado durante el primer taller de estandarización del análisis seminal (PLEAS), realizado en Santiago de Chile, mayo del 2010. Posteriormente se aplicaron los nuevos valores indicados como "límite de referencia inferior" (LIR), en el estudio del análisis seminal realizados por varios autores (2003 al 2010). Los resultados obtenidos indican que el 81% de los investigadores latino americanos creen que el nuevo manual estandariza mejor la concentración espermática, un 96% está de acuerdo con la nueva subclasificación en la motilidad...

Provedor de dados: 77
Autores: Asenjo-Lobos,Claudia; Manterola,Carlos.
Para realizar una práctica clínica basada en la evidencia (PCBE), se requiere adquirir una serie de habilidades; entre ellas la búsqueda de literatura en forma sistemática y eficiente y la aplicación de reglas formales para la evaluación de la literatura encontrada. De este modo, se logra obtener de forma precisa la mejor evidencia disponible. Es así como, se podría resumir que el proceso de PCBE incluye varios pasos, uno de los cuales es el análisis crítico de la evidencia encontrada en la búsqueda de la literatura. Es fundamental comprender que no toda la información proveniente de revistas científicas es confiable o verdadera y por ende adecuada para ser instaurada como guía para la práctica clínica. Por tal razón, la información debe ser analizada de...

En la actualidad se acepta que la obesidad es un grave problema de salud pública. La situación es aún más preocupante entre las personas con discapacidad intelectual, especialmente entre las mujeres. Afortunadamente recientes estudios sugieren la utilidad del ejercicio como estrategia frente a la obesidad. Sin embargo, la mayoría de estos estudios utilizan grupos mixtos (hombres y mujeres) o varones, siendo escasa la información sobre un grupo homogéneo de mujeres. Por consiguiente nos planteamos como hipótesis que un programa de entrenamiento de 10 semanas podría reducir el porcentaje de masa grasa y la distribución abdominal en mujeres obesas con síndrome de Down. En nuestro estudio participaron 20 mujeres adultas (18-30 años) con un cociente intelectual...

Amelogenin is one of the enamel matrix proteins secreted by ameloblasts during enamel formation in tooth development. Recent studies showed that the amelogenin is expressed in chondrocyte. Lysosome-associated membrane proteins (LAMPs) have been identified as binding partner proteins to amelogenin and it has been suggested they act as signaling receptors of amelogenin. The purpose of this study is to clarify the localization of amelogenin and LAMPs in growth plate cartilage and cartilaginous nodules in micromass culture. Mouse knee joints including tibia growth plate at 4 weeks old and micromass cultures of limb bud mesenchymal cells after 2 weeks were fixed in paraformaldehyde, routinely processed, sections were cut and immunostained with amelogenin,...

Autores: Ennes,Jussara Peixoto; Medeiros,Rafael Monteiro de.
The mandibular foramen constitutes an anatomical repair to anesthetics and surgical procedures. Its localization is surrounded by difficulties and a source of disagreement. The goal of this investigation was to identify the MF location in human mandibles presenting variable number of teeth and in edentulous ones. And from the data given by the literature, short anesthetic needles were analyzed as to their suitability to block the inferior alveolar nerve by the pterygomandibular technique. The medial faces of 91 mandibular ramus were photographed. The exemplars presented different number of teeth, from none to 16. Measurements on the digital images were taken. The results revealed great variety on the position of mandibular foramen. They have been localized...

Autores: Neri,Letícia Oliveira; de Amorim,Milena Menezes; Campos,Stella Andrade Rodrigues; Sanada,Luciana Sayuri; Fazan,Valéria Paula Sassoli.
Although numerous studies investigate sensory recovery of the hind paw of the rat after nerve damage, still no comprehensive overview of its normal innervation is present in the literature. We investigated the morphometry of myelinated fibers in the sural and saphenous nerves and analyzed their size distributions in young rats. Six 30-day-old female Wistar rats were perfused with 2.5% glutaraldehyde and their right and left sural and saphenous nerves were prepared for light microscopy and morphometry. Morphometric data were compared between segments (proximal versus distal) and sides (right versus left) for the same nerves. Also, segments from right or left sides were compared between nerves (sural versus saphenous). Both, the sural and saphenous nerves,...

Autores: Izadpanah,Melika; Alizadeh,Rafieh; Minaee,Mohammad Bagher; Heydari,Leyla; Babatunde,Adebayo; Abbasi,Mehdi.
One of the proposed mechanism by which varicocele induces its damage is excessive release of nitric oxide (NO). Several studies have shown the role of NO in poor sperm quality in infertile patients with varicocele. Scientific studies have demonstrated the beneficial effects of curcumin on the sperm parameters. Curcumin as an atoxic antioxidant can reduce production of NO. The aim of this study was to determine the effect of curcumin on NO levels and investigate if curcumin can improve sperm parameters in varicocelized male rats. Thirty male Wistar rats were randomly divided into 5 groups (V1 and V2 (varicocele), T (treatment), Sh (sham) and C was control). In groups V1, V2, T and Sh, the left renal vein was partially ligated to induce varicocele. In groups...

Autores: Murlimanju,B. V; Prabhu,Latha V; Pai,Mangala M; Ganeshkumar,C; Sarvepalli,Ankamma.
A lumbosacral transitional vertebra is a rare congenital anomaly which occurs because of defect in the segmentation of the lumbosacral spine during development. During routine osteology classes for the medical students at the Kasturba Medical College, Mangalore, India, one of the sacra showed the fusion of the fifth lumbar vertebra with the sacrum. The specimen showed an incomplete fusion (sacralization) on the left side and the transverse process was of the large butterfly shape, while on the right it was about the usual size. Though this variation is well known, the details of this anomaly are rarely reported in the anatomical literature. Since there is a strong relationship between the lumbosacral transitional vertebrae and low back pain, this anomaly...

Autores: Smok,Carolina; Rojas,Mariana.
La osificación es un proceso que ocurre durante la embriogénesis al iniciar el periodo fetal. Se caracteriza por una condensación de células mesenquimáticas con una bipotencialidad condro y osteogénica para formar tejido óseo mediante osificación endocondral y membranosa respectivamente. La regeneración ósea es la respuesta generada con el fin conseguir la restitución del tejido tras un trauma. Este evento se caracteriza por la formación de un callo perióstico secundario cuya ontogénesis sigue los patrones embrionarios al presentar ambos tipos de osificación, además de la regulación molecular propia durante la etapa fetal, concluyendo que ambos procesos están íntimamente relacionados durante la ontogenia del individuo, con la excepción del proceso...

La dimensión vertical es una medida aproximada de las relaciones fisiológicas intermaxilares. Su obtención es un proceso sensible y metódico que produce efectos craneofaciales colaterales cuando es erróneamente lograda. Los conceptos individualistas de su obtención deben ser cambiados e interiorizados de una manera colectiva debido a la complejidad de la dinámica masticatoria que exige una perspectiva más amplia de esta noción. La correspondencia entre la dimensión vertical y lo funcional-disfuncional cráneo-cervical es innegable y va mas allá de una relación exclusivamente dental.

Provedor de dados: 77
Autores: Torres Muñoz,Sebastián René; Cantín,Mario; Pérez Rojas,Francisco Javier; Suazo Galdames,Iván.
Facial reconstruction for forensic sculpture aims to reproduce the face of an individual for identification. This technique is based on the knowledge of the facial soft-tissue thickness, which differs in terms of sexual dimorphism. However, in terms of asymmetry, the real significance of the soft-tissue thickness on both sides of the face is not considered to make an approximation of the morphofacial characteristics of an individual. This study analyzed the facial tissue thickness of 32 adult Spanish corpses of both sexes in six bilateral cephalometric landmarks through the needle puncture technique, comparing the measurements of right and left sides. No significant differences were found when comparing the soft-tissue thickness on the right and left sides...

The sinonasal region in humans is one of the regions that commonly shows anatomical variations. These variations can be easily diagnosed by paranasal CT evaluation. One of these variations is Crista galli pneumatization. In recent years, there have been opinions supporting the hypothesis that pneumatization originates from the frontal sinus. In this study, we planned to evaluate whether the presence of Crista galli pneumatization varied in pre-adult and adult periods. In this retrospectively designed study, 218 coronal paranasal CT images collected between 2012 and 2013 were evaluated. Patients were divided into two groups according to age under or over 18 years. In the group under the age of 18 (97 cases), pneumatization was detected in 2.1 % of samples,...

Provedor de dados: 77
Autores: Alibardi,Lorenzo.
The present ultrastructural study on developing and regenerating feathers of chick and zebrafinch describes the ultrastructural changes that occur during the differentiation of barb cells that leads to the formation of the ramus of barbs. Differently from barbule and barb cortical cells that accumulate feather keratin, barb medullary cells undergo to lipid degeneration. Eventually, lipids disappear and medullary cells become empty cavities in the central part of the ramus. In barb medullary cells feather keratin is accumulated in few peripheral bundles that merge with those of cortical cells to fom the wall of the ramus. The latter is joined with branching barbules. The process that controls the transition from keratin-synthesizing to lipid-producing barb...

Autores: Suazo Galdames,Iván; Roa Henríquez,Ignacio; Cantín L,Mario.
The sex chromatin or Barr body is a condensation of chromatin present at the nucleus of cells in female individuals. Their observation is possible in different cell types and is used for the rapid diagnosis of biological sex. The observation of this condensation in cells of the pulp tissue can be useful in the forensic diagnosis of sex, primarily because of the protection it give dental hard tissues, but its diagnostic value has not been tested. The purpose of this study is to analyze the diagnostic value of the observation of sex chromatin in cells of the pulp tissue. We used 40 premolars and third molars20 from men with a mean age of 20.6 years (SD 8.8) and 20 from women with a mean age of 20.4 years (SD 7.4). The pulp was obtained from teeth extracted...

An Unusual Termination of Seven Veins in the Jugulo-Subclavian Junction
Provedor de dados: 77
Autores: Panagouli,Eleni; Tsaraklis,Athanasios; Gazouli,Ioanna; Venieratos,Dionyssios.
During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

Rules, formulas and statistical tests have been widely used in studies that use continuous variables in the normal or Gaussian distribution or other tests whose data fit this type of distribution (t and z distributions) and whose parameters can be defined. However, there are cases in which the model and goal of the scientific work allow only the use of discrete or nominal variables. The absence or presence of a structure or organ (muscles, nerves, blood vessels, bones, and ligaments), characteristics associated with these organs, such as the source of nerves, vessels and muscles and the distribution of nerves and vessels are discrete and / or nominal variables that do not fit the Gaussian distribution, nor of z or t, unless the measures of these structures...

The mechanisms to obtain and store skin toxins in frogs in of the family Dendrobatidae are not completely understood. In order to contribute to understand how toxins are stored, we provide a histological description of the cutaneous glands of the species Phyllobates bicolor. The skin of two adult frogs was examined through three histological staining techniques (hematoxilin-eosin, PAS and Masson Trichrome) using conventional optic microscopy. The skin of Phyllobates bicolor contains two types of exocrine glands: mucous and serous, which empty their products to the epidermal surface through an intra-epithelial duct that leads to a stoma. The mucous and serous glands and the intercalated ducts are surrounded by a discontinuous sheath of myoepithelial cells,...

The greater palatine foramen (GPF) conducts the greater palatine nerve, responsible for the innervation of the posterior hard palate. The morphometric knowledge of the GPF is essential in the anesthetic interventions required in maxillofacial surgical procedures. The aim of this study was to evaluate the location and shape of the GPF in dry skulls of adults from Southern Brazil. Male (n = 65) and female (n = 29) skulls were studied, and the distance measurements from the middle of the GPF to the mid-sagittal plane (MSP) and to the posterior border of the hard palate (PBHP) were analyzed using a digital caliper and a ruler. The mean GPF-MSP distance in the right and in left sides of male skulls were 15.6 mm and 15.4 mm, respectively, and in female skulls,...

Toxicity of Sucralose in Humans: A Review
Provedor de dados: 77
Autores: Rodero,Ademir Barianni; Rodero,Lucas de Souza; Azoubel,Reinaldo.
Sucralose is a non-nutritive artificial sweetener, 600 times sweeter than sucrose, and is very stable at high temperatures, among other characteristics. It was approved by the FDA, in 1999, to be utilized in foods, beverages, pharmaceutical products, diets and vitamin supplements. Studies suggest a diffusion, through the placental barrier, of small doses of sucralose and its metabolites. Its hydrolysis products (4-CG e 1,6-DCF) are more rapidly absorbed than sucralose: 4-CG is excreted intact in the urine, and 1,6-DCF undergoes reduction with elimination by the urine or rapid conjugation with glutathione. Various organs can be affected by ingestión of high doses of sucralose. As a result of the rise in global consumption of sweeteners and light- or...

The cephalic and pectoral girdle structures of the heptapterin Hepapterus mustelinus (Nemuroglanis clade') are described and compared to those of two representatives of the other, more plesiomorphic, main heptapterin group, namely Goeldiella eques and Rhamdia guatemalensis ('basal clade'), as well as of several other catfishes, as the foundation for a discussion on the synapomorphies and phylogenetic relationships of the Heptapterinae. In addition to the five synapomorphies commonly referred in the literature, there is another potential Heptapterinae synapomorphy: the well-developed maxilla forming a completely closed, deep tube to enclose the base of the maxillary barbel. The subfamilies Pimelodinae, Heptapterinae and Pseudopimeodinae seem to form a...

Vertiginous Syndrome Associated with Incorrect Anesthesia Technique to Block the Maxillary Nerve via the Greater Palatine Canal: Case Report and Anatomic Correlation with Cadaveric Parts
Provedor de dados: 77
Autores: Soto,Reinaldo; Cáceres,Felipe; Lankin,Jorge.
The anesthetic technique through the greater palatine canal seeks to block the maxillary nerve in the pterygopalatine fossa and anesthetize a large area, including the pulp and periodontium of the arch in question. After applying this technique in a patient, it failed to obtain the expected result. The patient began to experience dizziness, nausea, vomiting and the sensation of fluid in the ear. She was evaluated in both the emergency room of the Hospital Parroquial de San Bernardo and at a private clinic without accurate diagnosis. Only symptomatic treatment was provided. The next day she was discharged with reduced symptoms, which disappeared completely during the day. We propose the hypothesis of a diffusion of the anesthetic solution into the middle...

Medial Patellofemoral Muscle: Report of a Rare Variant
Provedor de dados: 77
Autores: Beddings Moreno,Ignacio; Burdiles Orellana,Álvaro; Contreras Olea,Oscar.
Muscle anatomic variants range from absence of a muscle to supernumerary muscles, with a spectrum of possibilities that include anomalous course, anomalous origin or insertion, accessory slips, and others. The most common muscle variants around the knee include aberrant origin and accessory slips of the gastrocnemius muscles, presence of tensor fascia suralis muscle, and accessory popliteus. The medial patellofemoral ligament is a distinct extra-articular condensation of fibers located superficially to the medial joint capsule. We describe the presence of an accessory medial patellofemoral muscle in the expected location of the medial patellofemoral ligament, which to our knowledge has not been described in the literature before.

Regeneration is defined as tissue renewal and functional restoration process of the damaged parts of the body after an injury. Ambystoma mexicanum, commonly named the Axolotl, is one of the unique vertebrates, which has a remarkable ability to regenerate their extremities following the amputation. Although the process of regeneration includes several periods, it can be divided into two main phases; blastema formation and dedifferentiation. In the couple of hours following the amputation, wound closure occurs by migration of epithelial cells around the amputation site followed by macrophage infiltration and dedifferentiation of cells to turn into stem cells. Accumulated stem cells form a very authentic tissue type called blastema, which is crucial for...

Parotid Gland with Double Duct: An Anatomic Variation Description
Provedor de dados: 77
Autores: Fernandes,Atson Carlos de Souza; Lima,Rafael Guimarães; Rossi,Marcelle Alvarez; Aguiar,Márcio Cajazeira.
The parotid is the largest salivary gland in humans producing an essentially serous secretion, which normally reaches the oral cavity through a sole duct (the parotid duct) after the latter making its way through the buccinator muscle to reach the mucosa lining the mouth at the level of the cheek.

Autores: Duque Parra,Jorge Eduardo; Barco Ríos,John; Peláez Cortes,Félix John César.
El objetivo de este trabajo es demostrar, con base en referentes de la literatura neurocientífica, que Santiago Ramón y Cajal no fue padre de la Neurociencia, pero sí uno de los pioneros de la ciencia neural. Para corroborar dicha aseveración se consultó información variada sobre Ramón y Cajal en la que se indicara que él es uno de los pioneros de la Neurociencia y se contrastó con el tiempo en que se instauró la Neurociencia como disciplina; luego se comparó dicha información con aspectos variados de otros personajes que pudieron no ser llamados fundadores de la Neurociencia. Se concluye que Santiago Felipe Ramón y Cajal no es el padre de la Neurociencia, aunque sí se resalta el que es considerado uno de los pioneros de la ciencia neural.

Autores: Ottone,Nicolás Ernesto; Prum,Natalia; Dominguez,Mario; Blasi,Esteban; Medan,Carlos; Shinzato,Sergio; Finkelstein,Diana; Bertone,Vicente Hugo.
The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40%. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation...

Autores: Velasco,Ignacio; Aguilar,Leonardo; Pastrian,Juan; Mebus,Cristina; Martínez,Benjamín.
Metastasic tumours to the oral cavity are extremely rare lesions that represent 1% of all oral and maxillofacial malignancies. Most reported cases involve the jaw bones than the soft tissues. Metastasis to the oral soft tissues most prevalently affects the gingiva and alveolar mucosa. Gingival metastasis may have an unremarkable clinical appearance and they can be difficult to distinguish from more common hyperplasic or reactive lesions that appear to be benign entities, such as peripheral giant-cell granuloma, pyogenic granuloma and peripheral ossifying fibroma. We present an unusual case of a testicular choriocarcinoma metastasized to the maxillary gingiva mimicking a reactive lesion. In addition, we also present a literature review of previous reported...

Provedor de dados: 77
Autores: Pellón,Mario; Rojas,Mariana; Saint-Pierre,Gustavo; Hartley,Ricardo; del Sol,Mariano.
It has been demonstrated that hypoxia retards the growth of fish, reduces the survival of their larvae, deforms their vertebral column, but despite this teleost fish have the ability to completely regenerate many of their tissues, particularly the retina. As we do not have enough information about the effects of hypoxia on the eyeball, orbit and retina of Atlantic salmon (Salmo salar), we propose the following objectives: 1) Compare the morphological changes of the eyeball of fish subject to hypoxia and normoxia. 2) Determine changes in the orbit structure. 3) Describe the retina of salmon alevins. 4). Recognize hypoxic cells using the anti-Hif1a antibody in the retina of alevins as a sensor. 5) Determine the Shh morphogenic expression in alevins exposed...

A Study on the Variations in the Formation of the Trunks of Brachial Plexus
Provedor de dados: 77
Autores: Shetty,Surekha D; Nayak B,Satheesha; Madahv,Venu; Braganza,Cilwyn Shalitha; Somayaji,S. N.
Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra- or extraoral donor sites. The present report we describe the use of anorganic bovine bone (ABB) based on three case reports under different modes: Membrane, rigid barrier and connective tissue graft. Clinical results show that under all conditions, sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histologic evaluation revealed trabecular bone in an almost mature matrix with resting particles of ABB. Depending on the original site situation, two step rigid occlusive...

Central nervous system of reptiles has the ability to grow and regenerate during adult life of the animal. Therefore, cells creating CNS of this animal class should compound substances or molecules enabling neuroregeneration. Cells directly involved in this process have not been clearly characterized, especially in cell culture environment. Morphology of reptilian glial adherent cells should be known better to find any differences from mammalian CNS cells. We isolated glial cells from olfactory bulb and cerebrum from gecko (Eublepharis macularius) and cultured separately. We have observed populations of cells with proliferative capacity in both types of cultures. Also, we have detected lipid molecules deposits within their cytoplasm, which localization was...

Autores: Fazan,Valeria Paula Sassoli; Rodrigues Filho,Ornar Andrade; Matamata,Fernando.
The mylohyoid muscle plays an important role in chewing, swallowing, respiration and phonation, being the mylohyoid nerve also closely related to these important functions. It has been postulated that the mylohyoid nerve might have a role in the sensory innervation of the chin and the lower incisor teeth while the role of the mylohyoid nerve in the mandibular posterior tooth sensation is still a controversial issue. Although variations in the course of the mylohyoid nerve in relation to the mandible are frequently found on the dissecting room, they have not been satisfactorily described in the anatomical or surgical literature. It is well known that variations on the branching pattern of the mandibular nerve frequently account for the failure to obtain...

Provedor de dados: 77
Autores: Basso,Ana Paula; Sidorkewicj,Nora Silvia; Casanave,Emma Beatriz.
Two methods of measurement of bullar dimensions (callipers and scaling from digital images) and subsequent application of four volume formulae (rectangular prism, cylinder, ellipse and elliptical cone) were tested to find the most appropriate non-destructive method for estimating the bullar volume in Chaetophractus villosus. Material for the study consisted in clean adult skull (n=22). Real volume was obtained from latex casts of the tympanic bulla. Each estimation was corrected by a factor based on the differences between the estimated and the real volumes. Highest accuracy (5-7 % of underestimation) and precision (coefficient of variation: 13.27 %) were obtained from callipers and application of rectangular prism, cylinder and ellipse formulae. The...

Sexual Dimorphism Determination by Piriform Aperture Morphometric Analysis in Brazilian Human Skulls
Provedor de dados: 77
Autores: Cantín López,Mario; Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
The sex determination of human skeletons is important in forensic and anthropological research. It can be carried out through qualitative or quantitative analysis of morphological parameters of dimorphism. The shape of the piriform aperture is one of the classic indicators of sexual dimorphism since it describes differences between males and females according to strong population-specific behavior. The purpose of this study was to analyze the presence of sexual dimorphism in the size of the piriform aperture and its relationship with individual skin color. We used 90 human skulls from the Collection of the Federal Universidad de Sao Paulo (UNIFESP), with registered data on sex, age and skin color (classified as white, black and brown). The dimensions...

Cordelia's Dilemma, Historical Bias, and General Evolutionary Trends: Catfishes as a Case Study for General Discussions on Phylogeny and Macroevolution
Provedor de dados: 77
Autores: Diogo,Rui.
As noted Gould in his recent and last book «The structure of evolutionary theory», discourses on the high importance and frequency of evolutionary trends have consumed a great part of the research on the history of clades. Although aware that natural selection theoretically yields adaptation to immediate environments, many authors defend such trends as generalised improvements somehow conferring advantages across most or all experienced environments. The high importance given to evolutionary trends is questioned by Gould, who considers that such a high importance given to such evolutionary trends bears no necessary relationship to the relative frequency or casual weight of these events in evolution, but mainly to a major bias: trends tell histories, and...

Autores: da Cunha,Marcelo Rodrigues; Laraia,Isabela Ortiz; Franco,Guacira R; Miguel,Natalia N; Maciel,Ana A; dos Santos,Geovane Ribeiro; Isayama,Ricardo Noboro.
Bone metabolism is influenced by different factors and muscle activity acts as a stimulator of bone plasticity. Conditions such as nerve injuries can compromise bone physiology due to muscle inactivity. Preview studies have shown that nerve damage reduces P substance and calcitonin gene-related peptides, also known as neuropeptides that may have a key role on bone healing. Therefore, this study evaluated the osseointegration of hydroxyapatite implants in tibial defects of rats submitted to unilateral sciatic nerve section. Twelve Wistar rats were divided into two groups (G1 and G2). In G1, the sciatic nerve was left intact and in G2 the left sciatic nerve was completely sectioned. An experimental tibial bone defect was then created in both groups and...

Physical effort stimulates an increase in oxygen consumption in tissues, generating toxic chemical species derived from oxygen (ROS), which are considered the initiators of the lipid peroxidation process (LPO), the major mechanism of cellular injury. As the essential mechanism for maintaining the electrolyte balance depends on an effective kidney function, oxidative stress in this organ can be a key factor in the development and persistence of hypertension. This study aimed to determine the kidney changes induced by a combination of fluid restriction and exercise in rats. The study consisted of 24 male Wistar rats of 90 days of age, divided into four groups, two of which were submitted to water restriction and exercise on a treadmill.Twenty-four hours...

Classification and Fascicular Analysis of Variant Branching Pattern of Femoral Nerve for Microsurgical Intervention: A Series of Thirteen Cadavers
Provedor de dados: 77
Autores: Singh,Rajani; Tubbs,Shane; Singla,Mukesh.
Femoral neuropathy associated with lower limb is treated by surgical intervention through activation/regeneration/grafting of nerve fibers by a nerve cuff electrode implant or neuro-prosthesis. These procedures require detailed and precise knowledge of neuro-anatomical variants of the femoral nerve and its fascicular anatomy so that the nerve injury can be investigated and treated more efficiently. The aim of the study is to uncover the variations both in the femoral nerve and its branches, to classify them and to bring out corresponding fascicular anatomy using a hypothesis based on the principle of consistency, continuity and traceability of fascicles. The study was carried out in the Department of Anatomy AIIMS Rishikesh using 13 matched lower limbs (26...

Many of Glycobyological aspects of human development remain still unclear, mainly in oral science, and this could be observed in a lack of literature with few and old papers about this subject. During tooth histo-morphogenesis changes occur in basement membrane composition, expression of signaling molecules and in localization of cell surface components, where glyco components could be involved. In this sense, this work aimed to analyze the ConA ligands commonly founded in glycoproteins cores and UEA-I ligands since fucolization is a Key event in many physiological and pathological processes. Therefore 15 jaws of human fetuses were ethically obtained, histologicaly processed and then submitted to lectin histochemistry with appropriated controls. The...

Provedor de dados: 77
Autores: Naidoo,N; Ishwarkumar,S; Lazarus,L; Pillay,P; Satyapal,K. S.
Recent studies have regarded the fibula flap as the benchmark for the reconstruction and treatment of compound wounds and lesions. Owing to its postero-lateral location within the leg, the application of the fibula flap is deemed aesthetically advantageous as the donor scar can be easily hidden. Since the fibula is anatomically characterized by a shaft and two extremities, this study aimed to investigate the nutrient foramen morphology and the relative fibular osteometry. Osteometric and morphological evaluation of 104 dry human fibulae, representing male and female individuals of the Black and Caucasian population groups that are native to South Africa, were conducted (Age range: 15 ­ 81 years old). The presence of single, double and six nutrient foramina...

Oxygen free radicals are considered to be important components involved in the pathophysiological tissue alterations observed during ischemia-reperfusion (I/R). In this study, we investigated the putative protective effects of melatonin treatment on pancreatic I/R injury. Sprague Dawley male rats were subjected to 30 min of pancreatic pedicle occlusion followed by 90 min reperfusion. Melatonin (10 mg/kg. s.c) was administrated 30 min prior to ischemia or I/R application. At the end of the reperfusion periods, rats were decapitated. Pancreatic samples were taken for transmission electron microscopy. The results indicated that ischemia created b cell damage as evidenced by dilatation between the nucleus inner and outer membrane and degeneration on islets of...

Autores: Hou,Qihang; Xia,Mi; Hu,Wiwei; Yu,Qinghua; Zhang,Bingkun.
Reducing nitrogen nutrients concentration in dairy food is economic for pig industry. Here, we used finishing pig as model to investigate the effect on colon mucosal barrier and nutrients absorption after reducing crude protein (CP) in dietary from 16 % to 13 %. The results showed that crypt depth, cells, claudin-1 and E-cadherin expression level will not be changed, which implied the integrity of colon mucosal structure. Furthermore, the expressions of ASCT1, EAAT3 and SGLT1 in colon were also maintained at normal levels in 13 % CP dietary. Interestingly, the CAT1 and GLUT2 expression were increased significantly after reducing CP level to 13 %, which might be attributed to the compensatory nutrients absorption. This study implied that 13 % CP was...

Classification and Analysis of Fifth Pair of Sacral Foramina in Indian Dry Sacra
Provedor de dados: 77
Autores: Singh,Rajani.
A sacrum with five pairs of foramina is an anatomical variant resulting from sacralisation of lumbar vertebra at cranial end or sacralisation of coccyx vertebra at caudal end. An unusual gross variation nurtures interest of anatomists and causes concern for clinicians when it mimics pathology. A sacrum with fifth anomalous pair of sacral foramina has been observed which prompted the author to examine the available sacra in the osteology lab of Department of Anatomy KG Medical University Lucknow, UP, India. Of the total sixty six observed sacra, those with five pairs of sacral foramina due to sacralisation of lumbar vertebra were found in eleven cases (16.6%) while those due to sacralisation of coccygeal vertebra were observed in nine cases (13.6%). These...

Previously we report long lasting effects on ovary of mice prenatally exposed to flunitrazepam (FNZ), a benzodiazepine with tranquilized action. In this work we find that the FNZ don't prevent the effects on ovary prenatally exposure to stress in mice. We studied adult females born from mothers that had been stressed by immobilization on day 6 ofgestation (GD-6) or group S, and from mothers stressed also by immobilization at GD-6, but which received a single oral dose of FNZ immediately after the stress group FNZS. The control groups were the SS that received the GD-6 saline solution and the group NT non-treated. Their ovaries were extracted for histology studies and to observe the activity of 3b hydroxysteroid dehydrogenase/isomerase (3 b-HSD). The...

Observation of Sex Chromatin in Exhumed Bones, Evaluation of their Diagnosis Value
Provedor de dados: 77
Autores: Muñoz,Patricia; Roa,Ignacio; Zavando,Daniela; Suazo Galdames,Iván.
Observation of sexual chromatin has shown to be very helpful in gender forensic diagnosis. In the present study we analyzed the diagnosis performance of the method in, non-treated or treated with conventional bone techniques, exhumed bone pieces. We used long bones of male and female individuals, the method applied is described in Suazo et al. (2010). In the non-treated exhumed pieces, the general accuracy of the method was 75%, while in the treated pieces the method was inapplicable due to the lack of cells in the tissue. Our results suggest that it is possible to determine the sex of aged human bones buried under different conditions through a fast and simple histological method, but the treatment with physical and chemical means eliminates the remaining...

Microscopic Anatomy of the Male Reproductive System in Echinolittorina peruviana (Mollusca: Caenogastropoda)
Provedor de dados: 77
Autores: Castillo,Viviana M; Brown,Donald I.
Echinolittorina peruviana (Lamarck, 1822), a gonochoric representative of the Littorinidae on the SE Pacific coast, has a male reproductive system adapted for internal fertilization. We describe this system at both macro- and microscopic levéis, particularly the compartmentalized organization of the gonad, and the morphology of the penis. The male reproductive system has a variegated conical gonad-digestive gland complex. The gonad presents three compartments, 1) gametogenic acinar among the glandular acini, 2) periacinar with a layer of fusiform somatic cells and, 3) interacinar with glycogen storage cells shared with glandular acini. Spermatogenesis occurs within the acinar gametogenic compartment, with the germinal line organized in centripetal form...

The ultimate goal of periodontal therapy is to repair the damaged periodontal supporting tissues, permitting regeneration of the periodontal ligament. However, the cell response, the supportive matrix and the bioactive molecules use have not yet been well established. Bone marrow mononuclear cells were extracted from rat femurs and tibiae and cultured on a cross-linked collagen membrane, bone graft, or molar tooth to compare cell attachment and early proliferation on these materials. Cell attachment was quantified by light microscopy at 24, 48 and 72h, and cell proliferation was observed under a SEM after 72h. After 24h, the number of cells on bone graft was similar to that of the control and more than twice compared to collagen membrane (q=7.473...

Body Composition Comparisons by Age Groups in Hungarian Adults
Provedor de dados: 77
Autores: Ihász,Ferenc; Finn,Kevin J; Lepes,Josip; Halasi,Sabolc; Szabó,Péter.
The assessment of body composition provides a basis for evaluating changes in adults as they age. If the fat content is shown to be too high, intervention to reduce storage fat is warranted. The purpose of this paper is to report differences in body composition in men and women across three age groups (young, middle aged, older) to describe potential changes in both fat and muscularity. In addition, if fat storage is shown to be located in the visceral area (around the internal organs), then an addition risk to health would be evident. A total of 1564 Hungarian adults were tested for body mass index (BMI) and body composition using a multi-frequency electrical impedance device to determine percent body fat (PBF), percent muscularity (M%), and visceral fat...

Autogenous bone grafts are considered to be the gold standard in bone regeneration because of their osteogenic activity; however, due to limited availability of intraoral donor sites and the need to resolve the demands of patients requires an alternative to these. Two male patients were submitted to implant surgery in two stages with 6 months intervals between each of them: the first was exodontia and placement of DBM graft into the socket; the second stage was the drill with a 2 mm internal diameter trephine in center of the alveolar ridge previously grafted with DBM and subsequent implant placement. The samples were analyzed under histological techniques. A very mature bone was observed at 6 months after DBM graft placement in the sockets, showing it to...

Autores: Hartley,Ricardo; Castro-Sánchez,Rodrigo; Ramos-Gonzalez,Benito; Bustos-Obregón,Eduardo.
At present it is not clear if male fertility is affected by intermittent hypobaric hypoxia (IHH). This is an important issue since a large human population works over 3000 masl. This study analyzes epididymal sperm, in adult Sprague Dawley rats after five cycles of IHH (7 days exposure to 4200 masl in a hypobaric chamber / 7 days at 500 masl). The animals were separated into groups of 8, one group was exposed to hypoxia (7 days), and the others to IHH for one to five cycles. Controls (500 masl) were examined at the beginning and at the end of the 70 experimental days. A duplicate set of rats treated with melatonin (supposedly protecting from hypoxia) was also examined, as were their controls, injected with 0,03% ethanol (melatonin solvent). Epididymal...

Provedor de dados: 77
Autores: Onkar,Deepali; Onkar,Prashant; Mitra,Kajal.
Undescended testes or cryptorchidism in the most common congenital anomaly of male reproductive system. The descent is multifactorial with gubernaculums playing major role. The failure of descent can be at trans-abdominal or inguino-scrotal phase. Locating undescended testes is important in view of low fertility and high rate of occurrence of neoplasm in them. Ultrasound is the standard imaging technique of choice in children with a non-palpable testis as it is non-invasive and does not use ionizing radiation. Position of testis is also important in deciding whether patient will need abdominal or inguinal exploration. The aim was to study the position of undescended testes by high frequency ultrasound and its embryonic explanation. Total 41 boys with...

In 2003, the UFG Faculty of Medicine, to revamp its educational project, reduced the hourly load of some subjects, among them those of anatomy, which in general leads to eliminate the practice of dissection. This practice is essential for the basic training of students, being then used in other sciences such as pathology. The objective of this study was to compare and link data between groups that made or did not make dissection after the anatomy course. Questionnaires were issued to 86 medical students from the UFG Faculty of Medicine, and from these, 10 made dissection and 76 did not. Analyzing the answers, it was found that both groups recognize the importance of this practice for the knowledge of the anatomy discipline and for future disciplines or...

There is no consensus about the precise definition of what the cardia is. Although this term is often utilized in the medical literature, it takes on a variety of meanings, depending on the context. For histologists and endoscopists, the cardia is a region of the stomach immediately below the gastroesophageal junction. However, the concepts of gastroesophageal junction used by histologists and endoscopists are not the same as used by anatomists. This junction is histologically defined as the abrupt transition from the nonkeratinized stratified squamous epithelium of the esophagus to simple columnar epithelium and corresponds to the endoscopically defined Z-line. Nevertheless, this epithelial change does not occur exactly in the anatomical transition...

Casseri fue un brillante anatomista y docente de la Universidad de Padua, cuya vida se vio ensombrecida por la eterna rivalidad con su mentor Fabrizio. Tras su muerte, la historia también le dio la espalda, y un cúmulo de hechos desafortunados ha ido otorgando a su discípulo Spiegel la credibilidad de buena parte de sus logros. A pesar de aportar un legado anatómico incuestionable, todavía hoy es el gran olvidado en muchos textos de la especialidad. Como tributo a su obra nosotros proponemos denominar a las hernias de la línea semilunar como Hernias de Spiegel-Casseri.

For radical surgery of the past, the precise definition of the clefts of the paranasal sinuses was of limited significance. In the recent years, the transsphenoidal approach to the pituitary gland has come into practice and the study of the surgical anatomy and relationships of the sphenoid sinus has gained increased significance. To better define this anatomy, 20 sphenoid sinuses in cadavers were dissected to reveal important anatomical relationships, dimensions, volume and pneumatization of the sphenoid sinus. The results of the study are discussed with particular reference to the important surgical anatomical features of the sphenoid sinus. The results also point towards the possibility of racial variations in terms of relationships of the sphenoid...

Supernumerary nostril is a very rare congenital anomaly, which includes additional nostril with or without accessory cartilage. In the present case of the left supernumerary nostril, a small cavity of around 3 mm diameter and accessory lower lateral cartilage were present. The cavity was lined with mucous membrane and filled with mucoid discharge .Nasal endoscopy of accessory nasal cavity revealed that it was small as compared to normal nasal cavity and did not communicate with the ipsilateral nasal cavity. The diameter of the normal anterior nasal opening was less on left side as compared to right side. Unilateral supernumerary nostril may occur because of the Assuring of the lateral nasal process during fetal growth.

Organophosphorous pesticides are a healh problem worldwide, mostly for agroworkers, which are around 2600 millions of person in the year 2001. Little is known about male reproductive damage elicited by these chemicals. The acute effects of malathion (single intraperitoneal injection), 1/12 the LD50 to mice were analyzed at 1, 8, 16, 35 and 40 days after injection, in terms of spermatogenic cell proliferation and apoptosis and of Sertoli cell compromise as revealed by immunocytochemical detection of CK-18 (cytokeratin). The micronuclei test was done to assess for genotoxic activity of the agropesticide. The results showed decreased germ cell number followed by compensatory spermatogonial proliferation by 16 days (as shown by thymidine-H3 testicular uptake),...

El ácido valproico (VPA) es el principal anticonvulsivante utilizado contra la epilepsia durante la gestación. Sin embargo, en etapas iniciales del embarazo actúa como teratógeno y ocasiona malformaciones como fisura labio-palatina, alteraciones en el desarrollo genital y espina bífida, siendo esta última la más frecuente. Esto se produce debido al aumento de especies reactivas de oxígeno, pudiendo contrarrestarse administrando vitamina E. El objetivo fue determinar si la vitamina E disminuye el daño en tubo neural y médula espinal de embriones y fetos de ratonas expuestas a VPA. Se conformaron 8 grupos de animales. A los 8 días post-fecundación se les administró a los grupos 1 y 5 suero fisiológico 0,3 mL; grupos 2 y 6 VPA 600 mg/Kg; grupos 3 y 7 VPA 600...

Autores: Nayak B,Satheesha; Mishra,Snigdha; George,Bincy M; Cherian,Saju Binu; Shetty,Surekha D.
Femoral artery is the major artery of the lower limb. It shows some variations in its branching pattern. One of the rare but clinically important variations is the origin of deep circumflex iliac and inferior epigastric arteries from it instead of from external iliac artery. We report here the origin of inferior epigastric and deep circumflex iliac arteries from the femoral artery bilaterally. Both the arteries passed up deep to the inguinal ligament and had a normal course and distribution after crossing the inguinal ligament. Knowledge of these variations is of importance in plastic surgery, anterior approach to the hip joint, draining psoas abscess or reducing a femoral hernia.

Método de Recuperación para Piezas Anatómicas del Sistema Nervioso Central
Provedor de dados: 77
Autores: Valenzuela Oróstica,Marcos; Soto Norambuena,Reinaldo.
El material anatómico del sistema nervioso central es cada vez más difícil de obtener. A pesar de estar fijado, es muy lábil y al ser expuesto a diversas condiciones ambientales durante las actividades docentes, se va deteriorando, resecándose, adquiriendo una consistencia rígida y un aspecto oscuro que finalmente hace difícil el reconocimiento de estructuras. De la misma manera, cuando obtenemos una pieza de un cadáver con larga data de fallecido, nos podemos encontrar con un encéfalo que por lo reseco de su estado, no presta mayor utilidad. El objetivo de esta técnica es recuperar estas muestras, para que puedan ser utilizadas convenientemente en el estudio anatómico. Se usaron distintos segmentos de encéfalo, incluidos algunos contaminados por hongos y...

Provedor de dados: 77
Autores: Hyogo,Akiyo; Kobayashi,Toshihiro; Garcia del Saz,Eva; Seguchi,Harumichi.
Human neutrophils stimulated by phorbol myristate acetate (PMA), an activator of protein kinase C, produce active oxygen by NADPH oxidase in intracellular structures. We added succinimidyl ester of dichlorodihydrofluorescein diacetate (H2DCFDA), which first emits fluorescence when oxidized with active oxygen species, to neutrophils to produce active oxygen, in order to investigate the antioxidant effects of protocatechuic acid, ferulic acid, and caffeic acid which belong to polyphenols and are widely distributed among plants. Particularly, we focused on examining whether these substances capture and eliminate active oxygen inside or outside the neutrophil cytoplasm and whether these substances inhibit NADPH oxidase. Fluorescence microscopy demonstrated...

Brachial plexus neuropathies are common complaints among patients seen at orthopedic clinics. The causes range from traumatic to occupational factors and symptoms include paresthesia, paresis, and functional disability of the upper limb. Treatment can be surgical or conservative, but detailed knowledge of the brachial plexus is required in both cases to avoid iatrogenic injuries and to facilitate anesthetic block, preventing possible vascular punctures. Therefore, the objective of this study was to evaluate the topography of the infraclavicular brachial plexus fascicles in different upper limb positions adopted during some clinical procedures. A formalin-preserved, adult, male cadaver was used. The infraclavicular and axillary regions were dissected and...

La influencia de la nutrición sobre la reproducción en ovinos es compleja y los resultados observados son variables. Planes nutricionales bajos pueden ser causa de una reducción de la sensibilidad del endometrio a la progesterona lo que afecta el desarrollo morfofuncional del endometrio en estadios tempranos de la preñez y por lo tanto va en directo detrimento de la sobrevida del embrión. La progesterona y los estrógenos actúan a través de receptores intracelulares específicos que median su efecto fisiológico. Por lo tanto el nivel de expresión de estos receptores es fundamental para el efecto hormonal. El objetivo del presente estudio fue analizar en forma conjunta la expresión de receptores de progesterona (RP) y estrógeno (RE), en el endometrio de...

Sexual Dimorphism in Histological Structure of Normal Rat Stomach
Provedor de dados: 77
Autores: Zhu,Lei; Wang,Jian Lin.
Fifty male and fifty female Spargue-Dawley rats were randomly chosen and used to study the sexual dimorphisms of stomachic histological structures. The rat stomach consisted of the nonglandular part and the glandular part. The gender differences of the nonglandular part existed in the thicknesses of the stratified squamous epithelium and the longitudinal muscle. These findings revealed that the male rat stomach may storage more foods than the female. The gastric glands occupied all the lamina propria in the glandular part. The thicknesses of the gastric glands of the female and male rat were 525.0 ± 95.9 µm and 472.0 ± 158.7 µm respectively, and the difference was very significant (p&lt;0.01). The gastric glands could be divided to two layers in the HE...

Recently, the curriculum and the educational methodologies associated with health sciences courses are being reviewed and adapted. Pre-clinical sciences, such as anatomy and embryology are as well subjected to those changes. In human embryology courses it is common to use models to represent the different phases of development to facilitate learning, since the students can see and touch the models, obtaining knowledge by analogies. The purpose of the present study was to investigate if the construction of models by the students during practical embryology classes would improve or facilitate their learning. One year after the classes, 60 students answered a questionnaire with nine objective questions, including spaces for suggestions and observations. The...

Origin and Development of the Coronary Arteries
Provedor de dados: 77
Autores: Silva-Junior,Geraldo de Oliveira; Miranda,Sandro Wilson da Silva; Mandarim-de-Lacerda,Carlos Alberto.
The formation of the coronary vasculature is a fundamental event in heart development and involves a series of carefully regulated temporal events that include vasculogenesis and angiogenesis. This review focuses the knowledge concerning the formation of the coronary arteries available so far and some molecular mechanisms involved in this process. Understanding coronary embryogenesis is important for interventions regarding adult cardiovascular diseases as well as those necessary to correct heart congenital defects. The insight of the coronary artery development as a result of ingrowth changed the understanding of several congenital coronary artery variations and anomalies described in gross anatomy.

The Dual Role of Senescence in Tumorigenesis
Provedor de dados: 77
Autores: Chuaire-Noack,Lilian; Sánchez-Corredor,Magda Carolina; Ramírez-Clavijo,Sandra Rocío.
Senescence was rendered a tumor suppressor mechanism based on the observation of its protective effect against cancer in young organisms under conditions of oncogene activation or inactivation of tumor suppressor genes. In addition to this beneficial effect, senescence has been deemed to have age-associated deleterious effects because, apparently, senescence not only recapitulates aging and therefore loss of function and tissue regeneration capacity, but can also induce preneoplastic changes in adjacent stromal cells, provoke degenerative diseases or induce the production of tumor cell growth promoting factors. For that reason, senescence has become an attractive therapeutic target against cancer. This paper reviews some of the latest findings on the role...

Spermatogenesis and the spermatozoon ultrastructure follow a common pattern in terrestrial oligochaetes. However, many of their characteristics are distinctive of each species and they are of great importance for phylogenetic and taxonomic studies. Germinal cells were studied through conventional electronic microscope techniques in order to go deep on spermatogenesis, especially on the mature spermatozoon ultrastructure of Eisenia foetida. Spermatogenesis occurs in seminal vesicles and follows a pattern comparable to that of some other oligachaetes species. Spermatozoon ultrastructural details revealed that it is a filiform cell, with the acrosome placed in anterior position, followed by the nucleus, the midpiece and the tail which flagellum has a 9+2...

HISTOLOGY OF THE JAW DEFORMATION IN SALMON OF SOUTHERN CHILE
Provedor de dados: 77
Autores: Venegas,Felipe; Montiel,Enrique; Forno,Pablo; Rojas,Mariana.
In adult salmon of the sea centres in southern Chile, a jaw deformation (JD) has been identified. It affects the dental and hyomandibular bones, which bend ventrally up to 90&amp;deg; of their normal position. The deformation affects also the dental articular bone. This pathology is related to weight loss and increased mortality of the salmons. It was empirically postulated that a probable cause for this anomaly was food from vegetal origin in the diet of the fishes (which are carnivores) Therefore, the present work aims at comparing the biostructure of jaw bone of salmons fed either with vegetal (soja and gluten) formulation or animal formulation, mostly fish powder. Fifty specimens were analyzed from Puerto Montt, 35 having JD and 15 normal control....

Aggressive Pregnancy Tumor (Pyogenic Granuloma) with Extensive Alveolar Bone Loss Mimicking a Malignant Tumor: Case Report and Review of Literature
Provedor de dados: 77
Autores: Martins-Filho,Paulo Ricardo Saquete; Piva,Marta Rabello; da Silva,Luiz Carlos Ferreira; Reinheimer,Daniele Machado; Santos,Thiago de Santana.
Oral pyogenic granuloma is a hyperplastic inflammatory lesion commonly associated to local irritation or trauma. Females are more affected than men probably due to the vascular effects of hormones that occur during puberty, pregnancy and menopause. In the pregnancy, the lesions are known as "pregnancy tumor" and tend to occur more frequently during the second and third trimester. In the oral cavity, histopathological examination is required for diagnosis, since the lesion is clinically indistinguishable from other reactive lesions and, usually, there is no evidence of bone involvement. The authors report a rare case of pyogenic granuloma with destruction of alveolar bone mimicking a malignant tumor in a 20-year-old woman in the 19th week of pregnancy.

Autores: Ajayi,Nasirudeen Oladipupo; Lazarus,Lelika; Satyapal,Kapil Sewsaran.
During routine dissection of the upper limbs of a Caucasian male cadaver, multiple variations of the branches of the brachial plexus were observed. On the left side, the musculocutaneous nerve was absent and the muscles of the anterior compartment of the arm were innervated by the median nerve. The median nerve was also formed from three roots viz; two from the lateral and one from the medial cord of the brachial plexus. On the right side, the musculocutaneous nerve contributed a long communicating branch to the median nerve in the distal half of the arm. There were also communicating branches between the ulnar and radial nerves in both limbs at the humeral level. The co-existence of these variations appears to be unique and has not been reported in the...

Pressure ulcers are tissue damage resulting from the constant pressure on the underlying soft tissue to bony prominences for long periods. Some of the most common ulcers are developed at the ischial tuberosities area (ITs). It has been found that stresses produced in the underlying tissue to the ITs may exceed 5 to 11 times the surface stresses, making it necessary to estimate the forces generated between the soft tissue and the ITs. However, it is not possible to determine these stresses in vivo in a patient, due to ethical reasons. This paper presents a mechanical model of the pelvis-soft tissue in order to study the behavior of contact forces. The model simulates the load on the ITs of a male subject of 70 kg weight and 1.70 m height, which were...

Bilateral Triad of Persistent Median Artery, a Bifid Median Nerve and High Origin of its Palmar Cutaneous Branch: A Case Report and Clinical Implications
Provedor de dados: 77
Autores: Ariyo,Olutayo; Shea,John.
We report the association of a persistent median artery, a bifid median nerve with a rare very high origin palmar cutaneous branch, presenting bilaterally in the upper limb of a 75-year-old female cadaver. The persistent median nerve with a bifid median nerve has been reported in patients presenting with carpal tunnel syndrome. Reports of this neurovascular anomaly occurring in association with a high origin palmar cutaneous branch however, are few. This subset of patients is at risk of inadvertent nerve transection during forearm and wrist surgery. Pre-operative magnetic resonance imaging (MRI) and high resolution sonography (HRS) can be used to screen this triad. MRI can reveal if the patient's disability is associated with a persistent median nerve, a...

The aim of this study is to examine the changes in the amniotic membrane diagnosed with gestational diabetes mellitus. In this study, as a control group human amnion membrane from normotensive pregnancies was collected from diabetic women at 28­35 weeks of gestation. Gestational diabetes (n= 6) and normal amnion membrane (n= 6) for a total of 12 units were received. Amniotic membrane thickness was measured (p&lt;0.0001) and it was significantly higher in GDM groups compared to control group. The diameter of the amniotic epithelial cell nuclei was measured (p=0.0022). Gestational diabetes results show that there was weakening between amniotic epithelial cell-cell junction. This study showed that structural changes in epithelial cells of amniotic membrane...

Sexual Differences in the Diameter of Coronary Arteries in an Adult Sri Lankan Population
Provedor de dados: 77
Autores: Ilayperuma,I; Nanayakkara,B. G; Palahepitiya,K. N.
Coronary artery disease is a major cause of human mortality. It is stated that females have worse outcomes than men following myocardial infarction and coronary revascularization. Sexual differences in the coronary artery diameters have also been speculated as one of the reasons for the above outcome. However, because of possible confounding effects, such as the body size and heart weight, it is unclear if there is a true sex-specific effect on coronary arterial size. The present study was undertaken to investigate the sexual differences in the diameter of coronary arteries in a group of adult Sri Lankan population. The diameters of the coronary arteries and their branches were measured at predetermined sites in a total of one hundred and two apparently...

Autores: Fernandes-Santos,Caroline; Souza-Mello,Vanessa; Faria,Tatiane da Silva; Mandarim-de-Lacerda,Carlos Alberto.
Quantitative morphology is a reliable tool in developmental, clinical and aging biology. Quantitative data of histological improvement and/or impairment due to dietary manipulations or pharmacological interventions draws the attention of countless researchers worldwide. Morphometry allows a wide range of two-dimension analysis to be performed, whereas image segmentation allows the measurement of a single structure or the determination of the intensity of its color after adequate immunostaining or even the area occupied by a specific sort of cell. When it comes to unbiased analysis, consideration should be given to suitable tissue perfusion, fixation and embedding, avoiding artifacts. Furthermore, tissue shrinkage should be taken into account. In order to...

The rat is probably the most commonly used animal in scientific research. There are many benefits to its use such as: ability to work a large number of animals allowing greater statistical validity, the relatively short life cycles. However, the scant literature regarding the anatomy and morphology of these animals is also old and not very descriptive. The objective of this research is to study the macroscopic morphometric aspects of several parameters that have not been described yet regarding the heart of Wistar rats in different phases of their lives. Thirty-six adult male and female rats (Rattus norvegicus) weighting 150-770 g were randomly divided into 6 experimental groups. The heart was then carefully dissected and removed from the chest.

Autores: Yang,Yan; Yang,Hui; Pan,Hongyin; Xu,Jue; Hu,Tao.
Alveolar bone dehiscences, which were "V" shaped defects related the margin of the alveolar bone, were common findings in different populations and decreased bony support of teeth. It was difficult to detect dehiscence during direct clinical examination. All of the previous studies on the prevalence of dehiscences were based on dry human skulls. In the current article, we evaluated the prevalence of dehiscences occurring naturally in a Chinese subpopulation, and prepared a classification of dehiscences using cone-beam computed tomography (CBCT). The high prevalence rate of dehiscences and different characteristics of each category suggest that it would be helpful for clinicians who perform periodontal surgery, endodontic surgery, implant surgery or...

A Case of Unilateral Fenestration and Duplication of the External Jugular Vein
Provedor de dados: 77
Autores: Snoj,Ziga; Cvetko,Erika.
The external jugular vein is increasingly being utilized as the recipient vein in head and neck free tissue transfers, and for cannulation in order to conduct diagnostic procedures or intravenous therapies. The variations in the patterns of its course, and knowledge of them, are therefore important. We report on a unique and previously non-described unilateral fenestration and duplication of the external jugular vein found during the neck dissection of a 77-year-old female cadaver. Embryological evaluation and clinical implications of the anomaly are described. Clinicians and surgeons performing neck vascular or reconstructive surgery should be aware of this variation of the external jugular vein in the hope of preventing inadvertent injury.

Autores: Zheng,Yong; Yuan,Qianqian; He,Xin; Lei,Yueshan.
Any compression of testicular arteries may lead to loss of spermatogenesis and gonadal hormone production, existence of the variational arteries is accountable in cases of vasoligation, orchidopexy and other surgical approach on them. Anomalies of the testicular blood arteries were observed during dissection of the pelvic cavity in a 68-year-old male cadaver. This report describes a very rare case of lack of testicular arteries. For the blood supply to the testis, thick deferential arteries form some vascular winding and loops and course accompanied by deferent duct to the testis. This case report would serve as ray of light for knowledge of the possible variations of the testicular arteries during surgical procedures.

Provedor de dados: 77
Autores: Kapoor,Kritima; Singh,Opinder.
The present study was conducted on six healthy early neonatal and six prepubertal buffalo calves to study the location, gross morphology, histomorphology and histochemistry of lymphoglandular complexes in proximal colon. In very proximal part of colon of buffalo calves, an irregular oval mucosal lymphoid patch was found grossly as a proximal colon (PC) patch. Histologically, in proximal colon patch of early neonates (3-4 weeks), an extensive invasion of mucosal glands was observed towards lymphoid nodules that were present in submucosa. The structure as a whole thus formed a complex known as lymphoglandular complex (LGC). Large number of such complexes i.e., LGCs were observed in submucosa of proximal colon at this age. At some places, invasion of mucosal...

The frontal sinuses can provide significant evidence for forensic identification. The peculiarity of the frontal sinus contours allows a precise and meticulous analysis, reducing the risk of errors on the part of the forensic experts. To describe the use of cone-beam computed tomography as an alternative to obtaining images of the frontal sinuses. In addition, it is proposed the adoption of some anatomic references to do the axial slicing, which should have its plan being tangent to the upper limit of the orbital cavities, as well as the sagittal slicing, which should be done under the midline, so that all sinus boundaries would be observed while error margin in obtaining comparative images would be reduced. The comparison of frontal sinus images by...

Provedor de dados: 77
Autores: Balcioglu,H. A; Kokten,G; Guven,Y.
Anatomists have become familiar with an ongoing debate about the integration of basic sciences into the clinical context or vice versa. Although various educational modalities in dental school curricula and changes in curricular strategies challenge anatomists, the priorities in teaching anatomy and the emergency of presenting fundamental concepts in order to integrate students' basic science skills into the clinic led educators to develop new teaching methods. A search for improved efficiency and impact of the presentation of knowledge to the students in order to foster positive feedback should be one of the major responsibilities of the educators in basic sciences. New gold standards, such as computer-based learning tools and computer-assisted...

Anomalies arising in the embryological development of the aortic arch and its branches are essencial in the emergence of variations in the origin and course of supra aortic vessels. Classically, 95% of cases, the aortic arch gives rise to the brachiocephalic artery, left common carotid artery and left subclavian artery. While the left vertebral artery arises normally from the left subclavian artery. In this presentation we describe two cases of the left vertebral artery being born of the aortic arch. The importance of anatomical knowledge of this arterial variety is fundamental for base neck and aortic arch surgery, in cervicothoracic trauma that compromises the vascular elements and in endovascular procedures in the region.

The pirarucu, Arapaimidae family fish, is one of the most important and emblematic species of Amazon. To investigate their circulatory system anatomies features were used 10 specimens with 74 cm medium total length, from river Araguaia lakes, Sao Miguel do Araguaia, Goias, Brazil. The fishes had their celomatic cavity open with dorsal aorta artery identified and cannulation where was injected synthetic latex. Fixation of those specimens was by injection of 10% formalin. In that specie, the coeliac-mesenteric artery is the only one arterial vessel responsible to digestive tract flow and always ramified from 2nd, 3rd and 4th left efferent branchial arteries. The stomach is flowing by coeliac artery and a gastric branch of the cecal ventral artery; intestine...

Statistical Approaches for Analyzing a Continuous Outcome in Experimental Studies
Provedor de dados: 77
Autores: Sanhueza,Antonio; Otzen,Tamara; Manterola,Carlos; Araneda,Nelson.
In experimental studies the outcome variable is measured at initial time, usually called "baseline", and then in several times called "follow-up" measurement(s). The study question of interest in an experimental study is whether there is a significant difference effect between treatment and comparison group, after intervention. In addition, one wants to estimate the difference effect between groups. This paper studies some of the strategies, including a simulation process, that one can be used for analyzing data coming from an experimental study as above, and considers using or not using the baseline measurements. Three parametric and two non-parametric strategies are evaluated considering only one follow-up measurement. The baseline measurement is...

Autores: Borgno,Laura; Scanniello,Varinia; Rompani,Omar; Laxague,Alejandra; Páez,Sofía.
La disrupción anatómica del esfínter es el mecanismo más común de incontinencia fecal. La creación de un mecanismo esfinteriano con control voluntario permite mantener la contracción en el reposo o durante los movimientos y es uno de los principios fisiológicos y quirúrgicos para la continencia. Esta corrección puede realizarse mediante la transposición de músculo glúteo mayor alrededor del ano y recrear así un esfínter voluntario. La gluteoplastía dinámica consiste en la colocación de un marcapasos que permite la estimulación eléctrica crónica intermitente del músculo esquelético, resultando en la adaptación de la contractilidad basal.

Provedor de dados: 77
Autores: Nayak B,Satheesha.
An abnormal artery arising from external iliac artery was found during routine dissection class for medical undergraduates. The artery took its origin from the external iliac artery midway between its origin from common iliac and termination as femoral artery. The abnormal artery divided into two branches; an ascending and a descending. The ascending branch supplied iliacus and iliac crest. The descending branch entered the femoral triangle by passing behind the femoral sheath. It supplied the muscles of femoral triangle and anastomosed with medial circumflex femoral artery. The knowledge of this variation may be of use for surgeons doing surgery of femoral hernia.

Autores: Pokhariyal,Ganesh; Hassanali,Jameela.
The variations in morphometric parameter of mammalian brains may be influenced by process of functional complexity, evolution and adaptation. Comparative analysis of linear measurements of cerebrum in the human and baboon has shown morphometric differences. In the present study linear measurements from human and baboon cerebrum (n=10 each) were used to predict various values for human and baboon brain and body parameters through multiple regression models. The average brain weights were found to be 2.08% and 0.84% of the body weights for humans and baboons respectively. The elasticity of regression models revealed that unit percentage increase in Occipital-Frontal (OF) distance would increase the human brain weight by 66.19%, while the baboon brain weight...

Cranial Capacity in an Adult Sri Lankan Population: Sexual Dimorphism and Ethnic Diversity
Provedor de dados: 77
Autores: Ilayperuma,I.
Cranial capacity exerts a close correlation with the volume of the brain. A large body of evidence shows a clear racial variation in cranial dimensions. Therefore detailed knowledge of the population specific data on biometric features of the cranial cavity is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its significance, little is known concerning the cranial capacity in Sri Lankans. Hence, the present study was undertaken to establish the cranial capacity in an adult Sri Lankan population. A total of 210 subjects with an age span of 20-23 years were included in the study....

Provedor de dados: 77
Autores: García-Garza,Rubén; Rodríguez-Vidales,Edgar Paolo; Soto-Domínguez,Adolfo.
The tissue microarrays (TMAs) were first called multitumor block. In 1998 was described the current technique, that uses an innovated sampling method for more than 1,000 cylindrical paraffin tissue core biopsies in a single paraffin block. TMAs are now considered as a useful powerful research tool in Histology and Pathology laboratories, for the standardization of immunohistochemical techniques along with in situ hybridization. However, one disadvantage to its widespread use is the high cost of professional paraffin tissue punches, and the complexity in the development of homemade devices previously described in other studies. This study describes a step by step process to develop four different home-made devices made with materials that are common in...

A Quantitative Assessment of the Morphological Characteristics of BeWo Cells as an in vitro Model of Human Trophoblast Cells
Provedor de dados: 77
Autores: Abaidoo,C.S; Warren,M. A; Andrews,P. W; Boateng,K. A.
In order to study the detailed morphology of trophoblast cells during human implantation, BeWo cells were cultured as spheroids in suspension culture. These cultures were then processed for light and electron microscopical examination. The present study showed that the BeWo spheroids consist of two cell types which are cytotrophoblast-like and syncytiotrophoblast-like. The cells with larger nuclear diameter made up only about 1% of the cell population and appear to be those of syncytiotrophoblast. Therefore the predominant cell type of the BeWo spheroids appeared to be relatively undifferentiated and cytotrophoblast-like. About 10% of the BeWo cells in the present study were mitotic, indicating a highly proliferative population. Total cell number increased...

Autores: Marques,J. M; Viegas,C; Dias,M. I; Zagalo,C; Gomes,P; Fernandes,M. H; Santos,J. D; Cabrita,S. C.
In medical sciences, any experimental animal model should be reproducible and adequate to the purpose of simulated human physiological response. In bone injury response research, when bone substitutes are in use, it is of primary importance that studied defects fail to heal unless treated with the tissue engineering therapy under study. This failure defines the concept of "critical size defect" (CSD) wich has different limits according to the animal species used and the location of the defect. Although this is a basic concept, when the aim of the study is to investigate the interface Bone-Biomaterial, it is of primary importance to obtain as much contact area as possible. In order to do so, we propose a modified surgical approach to the classical...

Autores: Issa,Joáo Paulo Mardegan; Tiossi,Rodrigo; Mello,Amaro Sergio da Silva; Iyomasa,Mamie Mizusaki.
The skeleton has several important functions, such as structural functions that provide mobility, support, and protection for the body. It also has an important function as a reservoir for calcium and phosphorus. The aim of this article is to show the principal hormones that are involved with the bone healing process. In this article, it will be pointed the mineral homeostatic mechanisms in the skeleton, controlled by the calcium-regulating hormones: parathyroid hormone (PTH) that maintains the normal extracellular calcium levels by enhancing osteoclastic bone resorption and liberating calcium from the adult skeleton; estrogen, considering that both osteoblasts and osteoclasts express estrogen receptors, it is reasonable to assume that the effects of...

Human Oscicular Chain Articulations: Asymmetric Sound Transmission
Provedor de dados: 77
Autores: Ramirez Aristeguieta,Luis Miguel; Ballesteros Acuña,Luis Ernesto.
The mechanism for conducting acoustic energy via middle ear oscicles is still a controversial topic and will remain so until consensus is reached regarding whether it amplifies or reduces sound transmission. 22 paired human temporal bone blocks and 1 left block were studied. Digital measurements were taken of the tympanic membrane, oscicular articulations and the oval window; the results were then correlated. A relationship of non-lineal areas was found amongst the structures being studied, suggesting a sound transmission relationship combining both sound reduction and amplification. A complex relationship of levers could be observed originating in an oscicular and articular asymmetric relationship suggesting an amplifying function in initial sound...

Autores: Raghavendra Babu,Y.P; Murlimanju,B.V; Kumari Sahu,Kausalya; Gupta,Kanika; Saralaya,Vasudha V.
We report a case of variant origin of the right coronary artery from the left posterior aortic sinus. This was observed routinely during a medico legal autopsy of a 58 year old male who died in a road traffic accident. Initially it was believed that the right coronary artery was absent since there was no obvious right coronary artery ostium from the anterior aortic sinus. However it was found later that the right coronary ostium was present just beside the left coronary ostium in the left posterior aortic sinus and the right coronary artery was arising from the left posterior aortic sinus. The right coronary artery had an intramural course between the aorta and pulmonary trunk, which is considered as very dangerous and life threatening. We believe that the...

Autores: Ghaus,Farah; Faruqi,N. A.
Foetal anatomy seems to be highly promising developing speciality in the recent past. Maxilla is the key to facial skeleton. Its anatomy in general and bilateral variations along with sexual dimorphism in particular are of great surgical and forensic importance.Thirty two maxillae of sixteen human foetuses (21 wks to 34 wks) were considered to measure lengths of infraorbital groove and canal, widths of ends of infraorbital groove, diameters of infraorbital foramen and the distances of latter from infraorbital margin and nasal notch. Groups I (21-25 wks) and II (26-30 wks) foetuses were crucial for bilateral variations for most of the parameters. Distance between infraorbital foramen and nasal notch showed variations on two sides in maximum foetal groups....

Exposure to physical or psychological stress causes brain damage ranging from minimal behavioural alterations to different neurodegeneration degrees implying the overproduction of oxidative-nitrosative compounds, apoptosis and cell proliferation. In the present investigation, we have analysed the effect of the chronic stress by immobilisation applied to pregnant rats over the forebrain development of the embryos. The morphometric analyses showed an accelerated evagination of the telencephalic vesicles in 12 days old fetus from stressed mothers. The forebrain perimeter and the thickness showed significative differences in relation to age-matched controls. This stress effect seemed reversible during subsequent gestational stages. This is the first work...

A three- year- old Doberman was presented with complaint of lethargy and weight- loss. Physical examination revealed a mass in the right abdomen. Laboratory abnormalities included anaemia, azotaemia and metabolic acidosis. Sonogram of the mass was an anaechoic area surrounded by hypoechoic tissue. The mass was located between the right kidney and ovary and showed papillary and tubular pattern of cystadenocarcinoma. Nephroureterectomy and ovariohysterectomy was performed; however bitch was euthanized owing to poor improvement, while necropsy of the left kidney revealed an end-stage kidney. It was concluded that the cystadenocarcinoma must have arisen secondary to a primary ovarian adenocarcinoma through stromal invasion.

The percent of morula in stage A (without fragmentation), stage B (&lt;25% fragmentation), stage C (25-50% fragmentation) and stage D (&amp;gt;50% fragmentation) and did not showed significant differences between two coculture groups. Thus, the phase that the endometrial stromal cells were in thereby did not affect on the quality of embryos.

Autores: Manikum,C; Rennie,C; Naidu,E. C. S; Azu,O. O.
The suprascapular notch (SSN) is important, as it is a risk factor in the development of suprascapular nerve entrapment syndrome. The purpose of this study is to describe the morphology of the SSN of a sample of normal scapulae in the Discipline of Clinical Anatomy, University of KwaZulu Natal. Sixty scapulae were used consisting of 37 males and 23 females (mean age 51 years). The superior transverse diameter and maximal depth of the notches were measured. Comparisons were made of the notch in relation to the maximal width and length of the scapulae, laterality and sex. The Rengachary classification method was adopted to describe the shape of the SSN. Analysis of morphological variations showed Type II- wide blunted V-shaped notch to be predominant (65%)....

Frequency of Common Variants in Genes Involved in Lipid-Lowering Response to Statins in Chilean Subjects with Hypercholesterolemia
Provedor de dados: 77
Autores: Rosales,Alexy; Pacheco,Alejandro; Cuevas,Alejandro; Saavedra,Nicolás; Zambrano,Tomás; Lanas,Fernando; Salazar,Luis A.
Interindividual differences in activity and expression of the metabolizing enzymes cytochrome P450 (CYP) 3A4 and 3A5 and the multidrug efflux pump P-glycoprotein (P-gp, encoded by ABCB1 gene) contribute considerably to lipid-lowering efficacy of statin treatment in subjects with hypercholesterolemia. Variability in the activity of CYP3A4, CYP3A5 and P-gp could be considered to result from genetic polymorphisms encoding their genes. However, the available data indicate that the frequencies of ABCB1, CYP3A4 and CYP3A5 gene polymorphisms differ significantly across populations. Thus, the aim of the present study was to determine the allelic frequency of three common variants of these genes in Chilean individuals with primary hypercholesterolemia (HC) and...

Autores: Ciuccio,M; Estecondo,S; Casanave,E. B.
The dorsum of the tongue of Dasypus hybridus (Desmarest, 1804) studied by scanning electron microscopy, shows conical and branched filiform, fungiform and vallate papillae. No foliate papillae were seen. Conical filiform papillae are placed in the apex of the tongue and posterior to the vallated ones. Branched papillae are compactly distributed over the entire dorsal surface of the tongue. Fungiform papillae are more abundant on the first third of the tongue and they are distributed between filiform papillae. Only two vallate papillae were observed placed in the posterior third of the tongue, surrounded by a deep grove. The presence of taste buds on fungiform and vallate papillae indicate that both are involved in the sense of taste, while the filiform...

Provedor de dados: 77
Autores: Kazemi,Masoomeh; Tekieh,Elaheh; Golabi,Sahar; Sahraei,Hedayat.
Based on previous studies, a variety of bioenvironmental elements including inappropriate nutrition, diseases, infections, stressors, and medications are involved in epigenetic changes. Drug abuse is one of the most important causes of epigenetic changes and a concern in today's world. Studies have shown that morphine use by pregnant mothers causes several disorders in mothers in addition to transferring abnormalities to the next generation (placenta and embryo). Epigenetic factors such as morphine cause changes in gene expression in placenta as the first embryonic defense barrier. Because placenta does all the nutritional exchanges between mother's and embryo's blood, placental health guarantees normal embryonic development. Many studies have been...

Autores: Torre,F; Erthal,R; Fernandes,R. M. P; Babinski,M. A; Cisne,R.
The Kaplan´s anastomosis represents the communication between the dorsal and superficial branch of the ulnar nerve distal to ulnar canal. In the present study, a case about this nerve communication, found in a male adult cadaver, is reported. Information about brachial plexus distal anastomosis is fundamental for interpretation of clinical and electrophysiological findings, in order to establish the precise diagnosis of neurological lesions at this level. Its relations with flexor carpi ulnaris muscle's tendon and with pisiform bone exposes it to iatrogenic lesions during surgery.

Provedor de dados: 77
Autores: Rodero,Ademir B; Batigália,Fernando; Azoubel,Reinaldo; Moura,Arianne Assis; Rodero,Lucas de Souza; Silveira Jr,Landulfo.
Sucralose is a sweetener of general use in over three thousand products (beverages, foods and medical diets), with utilization currently permitted for the general population in more than 80 countries, including for women of reproductive age. There is little information on the safe use of sucralose, and experimental studies have suggested that the administration of some sweeteners, by diverse routes, retards not only fetal and placental development but also umbilical cord size. The present study aimed to estimate the fetal and placental weights and umbilical-cord length in fetuses from rat dams, after ingestion and non-ingestion of sucralose. In the treated group (5 dams), sucralose was administered (via gavage) at the dose of 30 mg/kg/day, from the 10th to...

Provedor de dados: 77
Autores: Almansour,Mansour I; Jarrar,Yazun B; Aloyaidy,Khalid A; Jarrar,Bashir M.
Methotrexate (MTX) is widely used in the treatment of some forms of cancer but having severe side effects. The present work aimed to investigate the protective role of propolis treatment against alterations induced by MTX on the hepatic and renal tissues. Rabbits were exposed to MTX (0.25 mg/kg), with or without propolis (50 mg/kg) while hepatic and renal biopsies were examined for histological and histochemical abnormalities. Methotrexate induced hydropic degeneration, pyknosis, sinusoidal dilatation and bile duct hyperplasia in the liver together with renal tubular degeneration, glomerular shrinkage and hyaline droplet precipitation. While propolis partially ameliorated some of the morphometric and biochemical alterations, none of the hepatic alterations...

Microscopic Anatomy of the Reproductive System in Two Sympatric Species of Fissurella Bruguiére, 1789 (Mollusca: Vetigastropoda)
Provedor de dados: 77
Autores: Collado,Gonzalo A; Brown,Donald I.
This study describes the microscopic anatomy of the reproductive systems of the keyhole limpets Fissurella latimarginata and Fissurella cumingi to test the existence of a possible isolating reproductive mechanism of morphophysiological type between species, and consequently to determine if the findings provide a valid taxonomic characteristic to distinguish these sympatric species. The results show that in both species the reproductive system is intimately associated with the excretory system. The gonad has a septa organization, and is connected with the distal portion of the right kidney by means of a renopericardial duct which functions as a genital duct. The gametes are evacuated to the mantle cavity through the right kidney opening. Besides transport...

An Osteometric Evaluation of the Mandibular Condyle in a Black KwaZulu-Natal Population
Provedor de dados: 77
Autores: Ishwarkumar,S; Pillay,P; DeGama,B. Z; Satyapal,K. S.
The mandibular condyle is the rounded protuberance that articulates with the mandibular fossa to form the temporomandibular joint (TMJ). The shape of the mandibular condyle may be classified according to five basic shapes viz. flattened, convex, angled, rounded and concave. Previous research indicated that variation in the shape and size of the mandibular condyle, exists and that population-specific differences may also occur. This study aimed to document the shapes and size of the mandibular condyle and determine their relationship with regard to sex, age and race (if any). The morphometric and morphological parameters of the mandibular condyle were measured and assessed in 54 dry mandible specimens (n= 108). The Wedel et al. (1978) classification scheme...

Among structural alterations that can be a risk factor for temporomandibular joint disorder (TMD) is condylar asymmetry. In order to measure the condylar asymmetry index in panoramic x-rays quantitatively, two methods have been proposed: those of Habets and Kjellberg. The aim of this study was to determine whether the x-ray method of measuring condylar asymmetries in orthopantomographies presents a minor tendency to error due to slight displacements of the head in the horizontal plane. 30 patients between 18 and 25 years of age were assessed. Each of them underwent three panoramic x-rays in three different positions: orthoradial, and at 5 and 10 horizontal angles. Then the Habets and Kjellberg measurements were taken. Habets' technique did not show any...

Apoptosis Durante el Desarrollo Embrionario de la Retina de Tortuga (Trachemys scripta elegans)
Provedor de dados: 77
Autores: Segovia,Y.
La apoptosis o muerte celular programada es un proceso que ocurre durante el desarrollo del sistema nervioso. El objetivo de este estudio fue observar los patrones de apoptosis que se producen durante el desarrollo embrionario de la retina, desde el estadio S16 al momento del nacimiento, mediante miscoscopía óptica y electrónica. Se utilizaron retinas de embriones de tortuga. Nuestros datos muestran que los primeros signos de apoptosis comienzan en el estadio S16, en la capa nuclear interna y alcanzan su máxima densidad tanto en la capa nuclear interna como en la capa de células ganglionares en S20, para extinguirse, prácticamente, en el momento del nacimiento. Por otra parte, la apoptosis sigue un gradiente centro-periferia.

Morphological Diversity of the Ovaries of the Mexican Teleost Fishes
Provedor de dados: 77
Autores: Kobelkowsky,Abraham.
The morphological diversity of the ovaries from a total of 90 species of teleosts in the Mexican fauna was analyzed. Ovaries were classified according to the following characters: their number, symmetry, fusion grade, trajectory, cross section, and topographical location. The fusion of both left and right ovaries was the character showing most diversity, mainly in the Cyprinodontiformes and its tendency to the viviparity. However, the most notably character was the extravisceral development of the ovaries in the Pleuronectiformes, implying the forward orientation of the gonoduct and the forward position of the female genital opening. The urogenital system of a typical perciform, Bairdiella chrysoura is proposed as a morphological pattern of the Teleostei.

Autores: Gunduz,Kaan; Buyuk,Cansu; Egrioglu,Erol.
The aim of this study was to assess the frequency of the BMC phenomenon in a Turkish patient population. Cone beam computed tomography (CBCT) images of 2634 consecutive patients were retrospectively reviewed. The Chi-squared test was used to determine potential differences in the distribution of BMCs when stratified by sex and side. Among the 2634 patients, 42 (1.7%) patients were found to have BMC. Of these 42 patients, 22 were female (0.8%) and 20 were male (0.7%) with age ranging from 29 to 68 years (mean age 47.47). Among the 42 patients, 39 (92.8%) of the BMCs were unilateral and three (7.1%) were bilateral. Approximately 24 cases (53.3%) were on the right side, and 21 cases (46.6%) were on the left side. All of the BMCs showed a mediolateral...

Provedor de dados: 77
Autores: Altug,Hasan Ayberk; Gulses,Aydin; Sencimen,Metin.
Odotogenic myxoma is a benign tumor which presents in 3% to 6% of all odontogenic tumors. According to the WHO classification, multiple radiolucent areas of varying size, separated by straight or curved bony septa with poorly defined borders are the radiologic characteristics of the condition. We report the case of maxillary odontogenic myxoma in a 21 year old man. The radiological feature of the current case was interesting, due to the size of the lesion and severe displacement of the upper third molar.

The mastoid process characteristics are of great utility in the diagnosis of sex. De Paiva &amp;amp; Segre (2003) described that sex diagnosis was possible based on the determination of the área of the triangle formed by the points porion, mastoidale, and asterion. The purpose of this study was to determine the existence of sexual dimorphism in the dimensions and the área of the mastoid triangle using statistical and discriminant function analysis. A total of 81 skulls of Brazilian individuáis that were part of the Museum of the Federal University of Sao Paulo (UNIFESP) collection were used, with sex and ages known: 50 men and 31 women between 40 and 70 years of age (mean 51.58 years, SD 7.319).

Autores: Bustos-Obregón,Eduardo; Castro-Sánchez,Rodrigo; Ramos-González,Benito; Torres-Díaz,Leandro.
At present it is not clear if male fertility is affected by intermittent hypobaric hypoxia (IHH). This is an important issue since a large human population works over 3000 masl. This study analyzes testicular changes in adult Sprague Dawley rats after five cycles of IHH (7 day exposure to 4200 masl in a hypobaric chamber / 7 day at 500 masl). The animals were separated into groups of 8, one group was exposed to hypoxia (7 days), and the others to IHH for one to five cycles. Controls (500 masl) were examined at the beginning and at the end of the 70 experimental days. A duplicate set of rats treated with melatonin (supposedly protecting from hypoxia) was also examined, as were their controls, injected with 0,03% ethanol (melatonin...

Lumbarisation of the First Sacral Vertebra a Rare Form of Lumbosacral Transitional Vertebra
Provedor de dados: 77
Autores: Adibatti,Mallikarjun; Asha,K.
In the lumbosacral region, anatomical variations occur with changes in the number of sacral vertebra either by deletion of first sacral vertebra or by the union of fifth lumbar or first coccygeal vertebra with sacrum. Lumbasacral transitional vertebrae (LSTV) is the most common congenital anomalies of the lumbosacral region. It most commonly involves the fifth lumbar vertebra showing signs of fusion to the sacrum known as sacralisation or the first sacral vertebra shows signs of transition to a lumbar configuration commonly known as lumbarisation. Complete transition can result in numerical abnormalities of the lumbar and sacral vertebral segments. Lumbarisation of first sacral vertebra is seen with a very low incidence of 2%. Knowledge of presence of such...

Quality and Language of Learning Objects Used in the Teaching of Human Anatomy
Provedor de dados: 77
Autores: da Silva,Karina de Carvalho; Santana,Otacílio Antunes; de Moraes,Sílvia Regina Arruda.
The traditional method of teaching Human Anatomy is based on the use of cadavers, text books and the use of images from an atlas. Learning anatomy by means of a cadaver contributes to the understanding of the shape, location and relationship of various organs and structures of the human body. However, the use of cadaverous material presents difficulties in terms of acquisition, conservation, quality and quantity. Thus, to improve the teaching of anatomy other learning objects such as anatomical models, videos and software, have been used. Each of these objects has its qualities as facilitators of knowledge, a fact represented by the impact that they have on the learning of anatomy translated into an improvement in student grades. However, such learning...

Using Standing Postures as a Practical Alternative to Gait Analysis for Assessing Normal Neuromotor Activity Variation of the Ankle Muscle Antagonists: A Soleus H-reflex and EMG Activity Study Comparing Patients with Hemiplegia to Healthy Subjects
Provedor de dados: 77
Autores: Pineda,Enrique; Sabbahi,M; Etnyre,B.
The purpose of this study was to evaluate and compare the soleus H-reflex amplitudes recorded in three standing postures between a group of patients with stroke and a group of healthy subjects. Nine ambulatory patients were compared with 10 healthy subjects. Measures were recorded during quiet standing (QS), heels raised (PO) and with the foot of the measured leg held just off the ground while standing on the opposite leg (SW). The results showed that patients, as opposed to the healthy group, did not inhibit soleus H-reflex in the SW posture. As opposed to evaluating ankle motor control during gait, the PO and SW standing postures appeared to offer a practical and objective method to assess soleus H-reflex when the purpose is to determine impairment (or...

Autores: Ciuoderis-Aponte,K. A; Ochoa-Amaya,J. E.
Con el término de zigomicosis (ZM) se designa un grupo de enfermedades causadas por hongos de la clase Zygomicetes, de los órdenes Mucorales y Entomophthorales, de varios géneros y especies. La presentación de ZM en animales ocurre esporádicamente en numerosas especies tanto en animales domésticos como silvestres (incluso en mamíferos marinos) y son pocos los casos comprobados de aislamiento e identificación del agente causal. Pocos hongos son considerados como neurotrópicos ya que tienden a localizarse en el SNC después de invadir el hospedador; sin embargo, la mayoría de los casos de meningitis o meningoencefalomielitis son parte de micosis sistémicas como la Candidiasis, la Criptococosis, la Aspergilosis o la ZM.

In order to explore the change rule of myoblast stem cells (satellite cells, SCs) in the denervated and re-innervated muscle and to investigate the cellular mechanism of the morphological and functional changes of the muscle, denervated muscle atrophy and nerve regeneration models were established in one-month-old rats. Postoperative indexes such as muscle wet weight, cell section areas, content of collagen fibers and DNA, electrophysiology, numbers of SCs in the triceps muscle of calf were dynamically tested. After denervation, the muscle wet weight and cell area reduced rapidly, and the collagen fiber content increased slowly. The number of SCs increased at first, and then declined suddenly two months later. From 4 to 5 weeks after re-neuralization,...

The chronic stress induces functional adaptations in the hypothalamo-pituitary- adrenocortical (HPA) and in the sympathetic-medullary-adrenal axis (SAM). Both axis are considered vital regulators of the homeostasis in vertebrates (Seyle, 1936; Ostrandrer et al, 2006. On the other hand, the placenta provides highly specialized functions during gestation that are critical for the normal development of the embryo/fetus (Soares et al., 1991). We hypothesized that the chronic immobilization (IMO) stress in pregnancy rats produces alterations in prolactin concentrations in placental tissue and also changes in the response of SAM axis. Chronic stress by IMO was applied on days 12, 17 and 21 of pregnancy rats. Relative concentrations and localization of placental...

Provedor de dados: 77
Autores: Castro Sánchez,Rodrigo; Bustos Obregón,Eduardo; Rojas Rauco,Mariana.
Vertebral Column Deformity (VCD) is a common pathology in Chilean salmon farms, lowering the quality and commercialization of the product. Hypoxia has been related to other musculoskeletal deformities, but not to VCD. This work analyzes the morphology of the vertebral column of Salmo salar alevins, cultured under hypoxic conditions (60% O2 saturation in the water tanks) for different time periods after hatching (2, 4, 6 and 8 days). They are compared with their normoxic controls (100% O2 saturation). Using histological (H/E), and morphometric techniques, it was found that the time of exposure to hypoxia is inversely proportional to the body length, notochordal diameter and thickness of its sheath. The organic response to hypoxia was quantified by...

In dental implant treatment or corrective surgery, a dental plaster model is produced to recognize the shape of the teeth. Understanding this dentition model is an important issue in prosthetic dentistry and craniomaxillofacial surgery. However, dental models are time consuming and costly to produce via traditional casting methods. We provide a method which makes dentition model from both a positive and a negative dental impression. Also we produce a system for making a digital dentition model using computed tomography (CT) data during the impression process. Additionally, the system allows the digital dentition model to be realized via a three-dimensional printer. The result simplifies production of the dentition model, since a physical model can be...

Provedor de dados: 77
Autores: Dahiru,Ahmadu Usman; Ojo,Samuel Adeniyi; Hamidu,Ahmed Umdagas; Danborno,Barnabas.
Various papers in the fields of Radiology, orthopaedics and radiographic anatomy have employed the use of angles measured on X-rays to make diagnoses, select treatment modalities in the management of foot disorders as well as predicting the outcome of interventions to these disorders. Calcaneal pitch (CP) and lateral talocalcaneal angle (L TCA) are angles that can be drawn on lateral standing radiographs of the foot and are used widely in the diagnosis, prognosis and choice of treatment modalities for various disorders of the foot. Data on these important radiological tools are lacking in Nigeria. Hence, the study is an attempt to bridge this gap. Using a hinge goniometer, the angles were measured from normal lateral standing radiographs of the foot. Mean...

Autores: Igbokwe,I. O; Grema,H. A; Ikpo,A. E; Mshelbwala,F. M; Igbokwe,N. A.
Out of 1608 Nigerian Sahel male goats (bucks) examined for cryptorchidism in an abattoir, 9 (0.6%) had right unilateral cryptorchidism. The coat colour-specific prevalence was highest among the brown bucks (2.1%); and was 0.8%, 0.6%, and 0.3% among black, white, back-and-white bucks, respectively. The condition was not found among bucks with brown-and-black, brown-and-white, and multiple coat colours. The right and left testes of normal bucks and the descended testes of cryptorchid bucks had comparable gross testicular measurements, but the retained cryptorchid testes were smaller in size. The estimates of the testicular measurements showed that testicular weights (with the entire epididymes), peripheral longitudinal lengths and mid-circumferences of the...

Autores: Ren,Yaru; Wang,Huan; Zhang,Zihui.
Changes in body size over ontogeny may influence the ontogenetic development of long bones, and thus important to our understanding of variation in morphological, physiological, and life-history traits within species. In this study, we sample the entire measurements of the Japanese quail (Coturnix coturnix japonica) of individual skeletons, to investigate the ontogenetic allometry of limb bone proportions by Reduced Major Axis (RMA) regression. The ulna and humerus were both positively allometric in relation to body mass, with their proximal ends growth more rapidly than other regions. Hindlimb bones exhibited more than one allometric pattern. The tarsometatarsus was negative; the femur presented positive allometry, with the width and depth of the proximal...

Molecular Epidemiology of Cystic Echinococcosis: Genotypic Characterization in Humans and Different Livestock
Provedor de dados: 77
Autores: Manterola,Carlos; Otzen,Tamara.
Echinococcus Granulosus (EG) is the major cause of cystic echinococcosis in humans and livestock in the world. In Chile is a zoonosis of great importance. The most frequently affected geographic areas are the Regions of Aysén, Los Rios, Los Lagos, Coquimbo and the Araucanía. Hence, it was discovered that in endemic areas of hydatidosis there could be several strains and genotypes of EG. In addition, there is evidence that some strains and genotypes are more infectious for human beings than others. This interesting phenomenon of the biology of EG has been studied using molecular biology techniques based on polymerase chain reaction (PCR) and DNA sequence analysis, which has made it possible to characterize the cestode species complex called EG sensu lato (s...

Fluorescencia de los Tejidos Queratinosos
Provedor de dados: 77
Autores: McMullen,Roger L; Chen,Susan; Moore,David J.
Utilizando una técnica de fluorescencia, registramos mapas de los fluoróforos presentes en varios tipos de tejidos queratinosos. Descubrimos que la fluorescencia de todas las muestras analizadas tienen rasgos en común. Observamos el aminoácido triptófano en todos los tejidos. Asimismo, nos parece que la máxima principal es debido a las kinureninas que son productos metabólicos y degradativos del triptófano. Esta máxima constituye un conglomerado de varias moléculas como L-kinurenina, 3-hidroxikinurenina y N-formilkinurenina. La proporción de kinureninas que tiene el triptófano depende del tipo de tejido y del grado de pigmentación. También, la longitud de onda de excitación y emisión depende de estos parámetros.

A Rare Pattern of Brachial Artery Variation: Case Report
Provedor de dados: 77
Autores: Jacomo,A. L; Martinez,C. A. R; Saleh,S. O; Andrade,M; Akamatsu,F. E.
Unlike the venous system, variations in arterial anatomy are less frequent and most of them affect visceral arteries. In limbs, variations of the brachial artery are the most reported and at least six different patterns have been described so far. The commonest is the superficial brachial artery which lies superficially to the median nerve. Much less prevalent are the high origin of the radial artery (brachioradial artery) or the existence of a doubled brachial artery (accessory brachial artery). We present a previously undescribed pattern of brachial artery variation. During dissection of the right upper limb of a 60 year-old male embalmed cadaver, we found the bifurcation of the brachial artery in the proximal portion of the middle third of the arm. Its...

Provedor de dados: 77
Autores: Starbuck,John M.
Morphometric approaches can be combined with 2D or 3D imaging to quantitatively evaluate craniofacial medical conditions depicted in material culture and to learn more about the culture being studied. A terra-cotta figurine (circa 500 A.D.) from the Tolteca culture of Mexico has previously been qualitatively "diagnosed" with Down syndrome (DS) based on the presence or absence of facial features typically associated with trisomy 21. The purpose of this research is to quantitatively test the hypothesis that the Tolteca figurine exhibits facial features consistent with DS. Landmarks (n = 24) were acquired from sex- and age-matched (5-20 yrs) facial images of DS individuals (n = 32), euploid individuals (n = 32), and the Tolteca figurine. Landmark coordinates...

Con este objetivo se hizo una disección en dos pumas adultos,donados por el Servicio Agrícola y Ganadero (SAG) a la Universidad Santo Tomás y por el Parque Zoológico Metropolitano a la Universidad de Chile. Los cadáveres fueron conservados mediante métodos anatómicos tradicionales, realizándosela disección muscular de los miembros torácicos. Nuestras observaciones mostraron que los músculos presentes son los mismos que los descritos para otros felinos como el gato doméstico, siendo el grado de desarrollo que alcanza cada músculo, el parámetro de variabilidad entre ambas especies. Se destaca, además, la presencia del músculo flexor digital superficial, que en textos clásicos es llamado...

Autores: Barros-Filho,José Duarte de; Hohl,Leandro dos Santos Lima; Rocha-Barbosa,Oscar.
The excavatory movements of the spade-snouted amphisbaenid Leposternon microcephalum (Reptilia, Squamata) was studied with the aid of videofluorscopy (X-ray) techniques. This allows the observation of skull and column movements along tunneling, and a more detailed motion observation, being so a novel approach for amphisbaenian excavatory rescarches. A single specimen of Leposternon microcephalum was kept in a glass terrarium filled with semoline, and filmed with a scopy (X-ray) machine. Fixed anatomical marks on the head of the specimen were put in drawings from the framed recordings. Selected sequences of the recordings were fragmented in isolated frames for motion observation. The analysis of the recordings revealed a repetitive pattern of excavatory...

In a sampled population of fall-prone elderly women, an exercise protocol was performed for 12 weeks on experimental group and at the end of exercise period, the strength and endurance of muscles and SF-6 Health Surveys were analyzed. Results showed that endurance and strength of muscles and also physical activity were improved in experimental group (P&lt;0.05). Group exercise program causes improvement in both strength and endurance of muscles in fall-prone elderly women. The effect of group exercise program on women may be related to differences in central nervous system of this gender in comparison with men.

Autores: Panagouli,Eleni; Lolis,Evangelos; Venieratos,Dionysios.
The gonadal arteries (testicular or ovarian arteries) emerge normally from the lateral aspect of the abdominal aorta, a little inferior to the renal arteries. Several other sites of origin of these arteries have been recorded with the renal and accessory renal arteries being the most common. In the present case report, the testicular arteries originated from the lower polar accessory renal arteries in both sides. The testicular veins followed had the usual origin and course, while an accessory renal vein was observed only in the right side. These anomalies were combined with an abnormal left ureter exiting from the lower pole of the kidney. Only one male cadaver among 77 adult human cadavers of Caucasian origin presented this set of variations (frequency:...

The extracellular matrix (ECM) plays an important role in the regulation of biological events such as the development of cell migration, proliferation and differentiation. Chronic sun exposure causes changes present in the ECM of actinic cheilitis (AC), a premalignant lesion of the lower lip which helps to understand the carcinogenesis of the lip. This study aimed to investigate elastin, the main component of solar elastosis alternating current in an attempt to establish the relationship between this protein and ECM in epithelial dysplasia. Paraffin embedded tissue sections of the lesions of 35 cases of AC were analyzed by immunohistochemistry for elastin, and became the association with the degree of epithelial dysplasia and age.

The localization of peroxidase activity in different cell regions is used as a criterion for the classification of the stage of maturation of mammalian mononuclear phagocytes with a positive peroxidase reaction indicating the presence of monoblasts, promonocytes, monocytes and macrophages. In this study it was evaluated the peroxidase activity of blood mononuclear phagocytes of this turtle detected at different stages of differentiation. The present observations suggest that, in turtles, the differentiation of mononuclear phagocytes occur in the blood circulation, in contrast to animals, where only are monocytes in circulating blood and macrophage differentiation occurs in other body compartments

Provedor de dados: 77
Autores: Jacob,Tony; Modgil,Vishal; Rana,Kum Kum; Das,Srijit.
Knowledge of the branching pattern of the abdominal aorta is clinically important for any abdominal surgeon operating on parts of the gut or neighboring structures like the suprarenals, spleen, pancreas, liver, kidneys and uréter. The presence of abnormal inferior phrenic artery associated with aberrant branch from the celiac trunk supplying the pancreas and duodenum is a rare anomaly. In the present case, we observed four branches of the celiac artery i.e. (a) left gastric artery (b) common hepatic artery (c) splenic artery and (d) an aberrant branch, which took a course inferiorly towards the pancreas. The aberrant artery supplied the body of the pancreas and gave a branch which supplied the horizontal part of the duodenum and then entered the transverse...

Autores: Navarrete Gómez,Patricia; Ormeño,David; Miranda,Antonio; Sánchez Gutiérrez,Raúl; Romero Mejía,Fernando; Parodi Rivera,Jorge.
Since the 1970s, There have been studies of the venom of Latrodectus sp. spiders, in particular the latrotoxin (LTX) of Latrodectus mactans. Many of the studies were aimed at understanding the action of the venom on the muscular system. Now accepted that LTX is able to generate a calcium-permeable membrane pore and modulate the release of synaptic vesicles that activate a receptor and induce cellular changes. Interestingly, when work began with venom obtained from the Latrodectus sp present in Chile, it generated clinical indications similar to the bite of this spider in another country, with some differences in intensity. The purpose of the first studies was to understand the systemic mechanisms of this venom, and other active compounds were studied for...

Using Standing Postures as a Practical Alternative to Gait Analysis for Assessing Normal Neuromotor Activity Variation of the Ankle Muscle Antagonists: A Soleus H-Reflex and EMG Activity Study
Provedor de dados: 77
Autores: Pineda,E. E; Sabbahi,M. A; Etnyre,B. R.
Soleus and tibialis anterior muscle EMG and soleus H-reflex are widely used to study ankle motor control during gait. Normally, the soleus H-reflex amplitude and EMG activity varies greatly through the course of walking. The examining of these events during walking requires space and resources that are generally found only in research oriented facilities, making difficult a more practical use. Earlier reports have suggested that normal variation of the soleus H-reflex and EMG could be determined from standing postures. Therefore, the main purpose of this study was to examine and determine which standing postures would reproduce the normal neuromotor variation of the ankle muscle antagonists. A total of five postures were investigated. The results of this...

Autores: Bayat,Parvindokht; Masoud,Farhadi; Ghanbari,Ali; Gannnnji-Harsini,Sedigheh.
Coronary anomalies are a group of congenital disorders. Most of the coronary anomalies are asymptomatic and benign but may cause myocardial ischemia and sudden death. Some of them are dangerous if they associate with other heart diseases. One of the congenital coronary anomalies is anomalous origin of the circumflex branch from the right coronary artery that is a rare congenital anomaly. We present a case of a 61-year-old man with history of hypertension, diabetes mellitus and hyperlipidemia. The coronary angiography reveals a circumflex branch from the right coronary artery.

Autores: Abumandour,Mohamed M. A; Gewaily,Mahmoud S.
In the present study, we focused on the morphology of L. sceleratus gills using gross anatomy, scanning electron microscopy as well as light microscopy. Results of this study revealed that the gill openings appeared as simple slits anterior to the pectoral fin without distinct opercular cover. The gill system consisted of three pairs of gill arches carrying two rows of gill rakers on its concave border and gill filaments on its convex border. SEM showed that all surfaces of the gill arch were characterized by the presence of the longitudinal ridges with many taste buds in addition to many spines around the rakers. Histologically, the gill arch was composed of curved bar of hyaline cartilage with slightly elevated area corresponding to the sites of gill...

An immunohistochemical analysis of 40 cases of oral squamous cell carcinoma was performed to evaluate the relationship between the expression pattern of death-associated protein kinase (DAPk) positive cells with the histological malignancy grading of these lesions. According to our results, eleven cases (27.5%) were high-grade malignancy tumours and 29 (72.5%) were low-grade ones. We found that 92.86% of the low-grade tumours were positive to anti-DAP kinase antibody whereas only 7.14% of the high-grade tumours presented positivity, and this difference was statistically significant (p&lt;0.01). Sixteen (55.2%) of the low-grade carcinomas exhibited moderate immunoreactivity whereas ten cases (34.5%) showed weak staining and three cases (10.3%) were negative...

Regional Histomorphometry of the Hepatic Inferior Vena Cava; a Possible Sphincteric Mechanism
Provedor de dados: 77
Autores: Bundi,P. K; Ogeng'o,J. A; Hassanali,J; Odula,P. O.
This study was aimed at identifying the changes in diameter and structural composition of the Hepatic Inferior Vena Cava in its infrahepatic, intrahepatic and suprahepatic portions. Eighty adult liver specimens from the Chiromo and Nairobi City mortuaries were used for morphometry, while twenty of them were processed for light microscopy. A constriction was noted in the mid-portion of the HIVC, while structurally; the intrahepatic portion had thicker fibromuscular adventitia. It is plausible that these are sphincteric apparatus to prevent backflow of blood in the Hepatic Inferior Vena Cava.

Skeletal Organization of Caudal Fin in Syngnathus abaster (Osteichthyes, Syngnathidae)
Provedor de dados: 77
Autores: Bartolino,Valerio.
The caudal skeleton is one of the most important tools to evaluate teleostean interrelationships, but just the anatomy of few species have been investigated. Black-striped pipefish (Syngnathus abaster) has never been examined for its caudal morphology. Here, red alizaryn is applied as specific staining for calcified structures, providing a better understanding of caudal skeleton organization. Our results and interpretation just partially fit with previous knowledge on other Syngnathus species. This emphasizes both the importance of facing same problems with new technics and methodologies, and the existence of a heterogeneous situation between close-related taxa

Histological Changes Implicated in Metastasis
Provedor de dados: 77
Autores: Díaz-Peña,Roberto; Castro-Santos,Patricia.
The process of malignancy emergence is associated with the acquisition of the capacity to invade other tissues. Several different biological processes have been described as involved in this process. Specifically, epithelial mesenchymal transition (EMT), a mechanism associated with embryogenesis and wound repair but also with mobility acquisition, is one of the concerned processes. In EMT an epithelial cell loses its epithelial characteristics, its junctions with neighbor cells and with the basal lamina and acquires mobility and mesenchymal characteristics. Also, factors of the tumor microenvironment have been described as involved. Tumor presence triggers a response in the surrounding tissue known as reactive stromal. It shows particular characteristics...

Provedor de dados: 77
Autores: Mahato,Niladri Kumar.
Literature related to the study of interspinous ligament in the lumbar region is sparse. Very few studies have elucidated the fibre orientation of this ligament at different lumbar levels. Male (19) and female (6) cadavers were dissected to expose the interspinous ligaments beneath all the lumbar vertebrae. Fibre attachments and directions were observed at all lumbar interspinous spaces. Thicknesses of the ligaments were measured at all levels. Interspinous ligament fibres were found to be oriented differently in the lumbar inter-spinous spaces. In the upper spaces the fibres were more horizontal. In the spaces beneath L3 and L4, fibres were curved and extended postero-superiorly. Fibres were thicker in the ligaments at the lower spaces in comparison to...

Las células germinales primordiales (CGP) son los precursores de los ovocitos y espermatocitos. Se caracterizan por ser las únicas capaces de retener verdaderamente la capacidad de desarrollo pluripotencial luego de la gastrulación. Estas células provienen del epiblasto, diferenciándose del resto de las células somáticas gracias a señales emitidas por el ectodermo extraembrionario y endodermo visceral tempranamente a partir de los días 6,0 a 7,5 dpc. en la especie murina. Luego migran a través de intestino primitivo y mesenterio dorsal hasta llegar a las crestas genitales alrededor de los 10,5 dpc. Las células germinales primordiales tienen una variada morfología y expresión génica, por lo tanto presentan distintos marcadores según el estadío en el que se...

HISTOLOGICAL STUDY OF THE SALIVARY GLANDS IN Dasypus hybridus (MAMMALIA, DASYPODIDAE)
Provedor de dados: 77
Autores: Codón,Stella Maris; Estecondo,Silvia; Casanave,Emma Beatriz.
The histology of the salivary glands of the armadillo Dasypus hybridus (Desmarest, 1804), was studied. Two pairs of salivary glands, parotid and submaxillary, and a salivary bladder are distinguished. Parotids are located anteriorly to the submaxillary glands. They are purely serous glands and excretory intralobular ducts, intercalated and particularly striated ones, are very numerous. Submaxillary glands are of greater size. They possess two lobes, which differs in their histology and histochemistry. The anterior lobe is mixed and the presence of numerous intralobular excretory ducts is remarkable. The bigger posterior lobe is mucous. Intralobular excretory ducts are observed, but they are not as abundant as in the anterior portion

Provedor de dados: 77
Autores: Schimming,Bruno Cesar; Vicentini,Carlos Alberto.
The cisternae of the Golgi apparatus of dog epididymal principal cells were labeled by the zinc iodide-osmium tetroxide method (ZIO). These cisternae were observed in the supranuclear region of the cytoplasm of the epididymal principal cells. Abundant endoplasmic reticulum cisternae, multivesicular bodies, mitochondria, lysosomes and vesicular elements of variable size were also found in this region, all associated with the sacks of the well-developed Golgi apparatus. The use of the ZIO method facilitates the observation and identification of the cisternae of the Golgi apparatus, thus permitting a correlation between structure and function in the so-called Golgi area. These ultrastructural characteristics support the secretory role of epididymal principal...

During routine dissection in the Department of Anatomy, multiple variations of forearm muscles in relation to the radial nerve and its branches were observed on the right side of a 34 year old male cadaver. Brachioradialis close to its origin was receiving muscle fibers from the brachialis and the radial nerve was passing in between them. Extensor carpi radialis brevis was absent and the extensor carpi radialis longus was giving two tendons in the second compartment of extensor retinaculum before its insertion while passing deep to the abductor pollicis longus. Absence of extensor carpi radialis brevis can be explained with the arrangement in lower mammals, where the two extensores carpi radiales are represented by one muscle. Ontogeny repeats phylogeny...

A comparative study of ocular morphometry was done in goats in Nigeria using the three major breeds. The result showed that the circumferences (mediolateral and anteriorposterior) were fairly constant between the breeds. The mean relative eyeball weight ranged from (0.39 ­ 0.59) x 10-3. Asymmetry was observed between the right and left eyeball weights and circumferences in all breeds and there was disparity in the asymmetry. It was also observed that heavier eyeball weights did not always correspond to a wider circumference. Female WAD and RS goats had significantly heavier (p &lt; 0.05) eyeball weights than the males but that was not the case in the Sahel breed. Animals above one year had consistently higher values in most of the parameters examined on...

Neuromuscular compartments are subvolumens supplied by a primary nerve branch with homogeneous fiber characteristics. This muscular organization is important for understanding the muscle function in relation to postural and dynamic implications and also is relevant for appraising meat quality. Current researches associate fiber muscle characteristics with perimortem processes that regulate muscle transformation into meat. It is known that pig muscle has four heavy chain myosin isoforms: I, IIa, IIx and IIb. Castrated male pigs were slaughtered at 100 kg live weight. Semitendinosus muscle samples of each subvolumen determined previously (R1, R2, R3, R4) were frozen in liquid nitrogen and reacted for myofibrillar ATPase and NADH-TR for determining fiber...

Femoroacetabular impingement syndrome (FAI) is a clinical entity that has been recognized in recent years as a frequent cause of pain and the early development of hip arthrosis. Subspine hip impingement is characterized by the prominent or abnormal morphology of the anteroinferior iliac spine (AIIS), which contributes to the development of a clinical picture that is similar to FAI. The aims of this study were to propose a new morphological classification of the AIIS, to determine the prevalence of the different AIIS morphologies based on this classification and to correlate the presence of said morphologies with different gender and age groups. The sample consisted of 458 hemipelvises from individuals of known age and sex (264 men and 194 women). Each...

We evaluated the sperm parameters such as cauda epididymis weight, sperm count, sperm morphology and sperm DNA stability of adult CF-1 male mice treated daily (oral exposure) with the toxic sodium arsenite (As, 7.0 mg/kg/body weight); Melatonin (Me, 10.0 mg/kg/bw), Me (10.0 mg/kg/bw) plus As (7.0 mg/kg/bw) and Negative Control (NaCl 0.9%) to assess acute (8.3 days), chronic (33.2 days) and recovery of testicular damage (66.4 days). Arsenic decreases the number of sperm from chronic treatment (33.2 days) and this effect continued until 66.4 days of treatment. The toxic effect of As also altered the morphology of spermatozoa in all treatment periods when compared to the negative control group. However, Metalonin induced protective effects in periods of 33.2...

It is feasible to think that the body composition assessment may be influenced by maturational and zinc status, especially in young athletes, which perform regularly high volume of physical training. In accordance, it seems important to clarify the impact of these factors in body composition assessment in athletes, since errors may lead to mistakes in training prescription and diet elaboration, and therefore affect the athletic performance. The objective was to compare (1) different methods of body composition evaluation in young soccer players stratified by zinc plasma levels; and (2) the two reference methods using skinfolds thickness in children (Slaughter's and Lohman's equations), considering the maturation level. In this cross-sectional study, fifty...

All organs of the immune system are innervated and almost all neurotransmitter receptors are present on immune cells. We studied the effects of sympathetic innervation in the development of amebic liver abscess (ALA) in rats. Our results showed that lack of sympathetic innervation promote a decrease in size of ALA. We found scarce amoebas, increased the number of neutrophils and a few collagen fibers surrounding the abscess, meanwhile in control group, we observed abscesses areas with typical necrosis including trophozoites and neutrophils. Macrophages were differentially distributed surrounding abscess area in control and vehicle groups, but equally located in and outside of the abscesses in sympathectomized rat. No significant differences were observed...

Autores: Henríquez,Ricardo; Olivares,Rossy; Caro,Gabriel; Guevara,Víctor; Lizana,Pablo.
Prenatal stress is associated with changes in body weight and size, and with disorders of the skeletal bone development process. However, there is a lack of documentation on the impact of prenatal stress on skull bone anatomy during the gestation period. Therefore, this research focuses on the short-term effects of prenatal stress on the skull bone anatomy of CF-1 mice on the day of birth. Methodology: Gestating females were divided at random into two groups (control and stressed). The experimental group was subjected to the stress of movement restriction during the final week of gestation. Upon birth the body weight of the progeny was evaluated (control group, n=34; stressed group, n=29). They were then cleaned and stained with alizarin red in order to...

Histotechnology is concerned with processing and preparing of the body tissue in such a manner as to enable a satisfactory study of it. Section cutting is an integral part of histology and histopathology. It is an art by itself requiring skill and knowledge on the part of technician or the person who needs to do section cutting. In the routine method of preparing paraffin sections, it is often encountered by the presence of artefacts like fine wrinkles or folds. Attempts have been made to remove the wrinkles by floating the sections in the warm water bath. However this method has not been able to remove all the wrinkles from the sections. We have designed a simple and reliable method, in which the paraffin sections were floated over the ethyl alcohol...

SUMMARY: The effects of acetylsalicylic acid (ASA) on intrauterine growth restriction induced by maternal ethanol consumption were studied. A single intraperitoneal dose of ethanol (2.96 g/kg body weight), injected on the 10th day of pregnancy (PD10), significantly reduced maternal weight gain, fetal weight, amniotic fluid volume and umbilical cord length. Meanwhile, ethanol did not affect placental weight or litter size. A single intraperitoneal dose of ASA (200 mg/g body weight), injected on the PD10, did not modify maternal body weight gain, litter size, fetal and placental weights and amniotic fluid volume, but significantly diminished umbilical cord length. Intraperitoneal injections of either ASA (200 mg/g body weight) or ethanol (2.96 g/kg body...

Calcific Metamorphosis with Pathological Root Resorption in Permanent Teeth: Morphohistometric Evaluation of Two Cases
Provedor de dados: 77
Autores: Fonseca,Gabriel M; Fonseca,Miguel M.
Calcific Metamorphosis (CM) is a pulpal response to dental trauma characterized by a deposition of hard tissue within the canal space. A tooth with CM usually presents a discoloration and a partial or total obliteration of the pulp canal space, and its vital pulp tests and symptoms are difficult. Since pulp necrosis cannot be supposed even the negative responses, the periradicular status is the only reliable criterion. Two permanent teeth diagnosed as CM and pathological root resorption, extracted from two males (22 and 53 years of age) due to severe mobility were prepared and sectioned for histological and histometrical evaluation. Images were captured, processed and measured in a total mapping of each specimen with software Pinnacle Studio 9.4® (Pinnacle...

Morphometric Examination of Red Fox (Vulpes vulpes) from the Van-Yoncatepe Necropolis in Eastern Anatolia
Provedor de dados: 77
Autores: Onar,Vedat; Belli,Oktay; Owen,Pamela R.
In the burial chamber M4 of the Van-Yoncatepe necropolis in eastern Anatolia, dated to the beginning of the first millennium before our time, fox skeletal remains have been discovered together with human skeletal remains. The fox remains consist of two skulls and a large number of skeletal (postcranial) bones. Examination of the material led us to the conclusion that five foxes had been buried in the chamber. Craniometric and osteometric measurements were carried out on the bones, and estimations of shoulder height and body weight have been calculated. Evaluation of all quantitative and qualitative data and comparison with modern fox species led to identification of the remains as red fox (Vulpes vulpes)

Due to its prominent role in major excretory pathways, the kidney is particularly sensitive especially to toxicity for antimicrobials drugs. Storage of these drugs in the renal cortex, their effect on renal cells, have consequences on the renal function, and then reabsorbed by renal tubules induce nephrotixicity. Our objective was to show the renal morphopatological alterations induced by gentamicin through the histochemical methods of routine periodic acid de Schiff (PAS) staining and imunohistochemical staining for the expression of the protein P53, which is considered as a marker for cellular apoptosis. This allows the early detection of tubular lesions. The renal morphopathologic findings were cell apoptosis, basal membrane interruption, mesangial...

Autores: García-Hernández,Fernando; Toro Yagui,Oscar; Vega Vidal,Manuel; Verdejo Meneses,Mauricio.
La retención intraósea y la erupción en malposición de 3Ms han sido muy estudiadas. Son causadas, probablemente, por disminución del tamaño de maxilares por cambios de hábitos alimentarios, reduciendo el espacio retromolar, lo que dificulta la erupción normal entre 15 y 25 años de edad, y produce patologías o molestias por comprometer estructuras orofaciales próximas. Lo anterior, ha promovido la exodoncia profiláctica u ortodóncica, incluso del germen dentario, con altos costos clínicos, hospitalarios, laborales, comprometiendo parte de los recursos destinados a financiar otros procedimientos quirúrgicos orales, además de riesgos durante cirugía, postoperatorio y lesiones iatrogénicas temporales o permanentes.

Potential Radioprotective Effect of AT1 Receptor Antagonists Against Morphological and Ultrastructural Changes in the Testes Induced by Ionizing Radiation
Provedor de dados: 77
Autores: Schwarz,Franciele Cristina; Mansano,Naira da Silva; Chies,Agnaldo Bruno; Viani,Gustavo Arruda; Spadella,Maria Angélica.
Radiotherapy is a source of human exposure to ionizing radiation. This pure energy causes deleterious effects on tissues, which result from oxidative stress, a phenomenon in which there is the participation of the Renin-Angiotensin System (RAS). The male genital organs are extremely radiosensitive and the action of radiation in the testes can significantly affect spermatogenesis. In search of potential radioprotective for male genital system, this study investigated whether the AT1 receptor antagonists minimize radiation-induced damage to reproductive tissues, by decreasing oxidative stress. Male Wistar rats were divided into six groups: 0 Gray (Gy) (control), 5 Gy (single dose in the scrotal area), telmisartan, losartan, 5Gy+telmisartan and 5Gy+losartan....

Provedor de dados: 77
Autores: Mahato,Niladri Kumar.
Neuro-vascular entrapments associated with variations observed in the origins of muscles in the arm are not uncommon. Though additional heads of biceps brachii muscle and extra fibres of brachialis muscles have been demonstrated earlier, bilateral additional heads of the biceps are rarely seen, especially with entrapment of the median nerve and the brachial arteries in both the arms. The present study reports conspicuous heads of the biceps brachii originating extensively from the medial inter-muscular septum, sharing its origin with the brachialis muscle. The extra origins of the muscle formed long musculo-aponeurotic tunnels. The tunnels measured eight centimeters in length extending from the lower arm to the cubital-fossa. Both the median nerve and the...

Provedor de dados: 77
Autores: Kaur,Manjinder; Bansal,Neelam; Uppal,Varinder.
The study was conducted on the testes of 18 buffalo foetii to reveal histogenesis and differentiation of different cells of testicular parenchyma. At 8.0 cm CVR (65 days) the seminiferous tubules were present at gonadal periphery and a network of polygonal mesenchymal cells was seen in the centre of testis. These tubules were surrounded by a distinct basement membrane and a single layer of peritubular cells at 10 cm CVR (74 days), which became double layered at 88.0 cm CVR (272 days). The testicular parenchyma at 12.0 cm CVR had two zones; outer zone having longitudinal tubules and inner zone having rounded tubules. But a reverse pattern of their arrangement was observed at 14.0 cm CVR (92 days). The pre-Sertoli cells were first observed in buffalo foetii...

Autores: Manterola,Carlos; Vial,Manuel; Pineda,Viviana; Sanhueza,Antonio.
In certain situations, which occur with particular frequency in the field of surgery and its related disciplines (where what predominates are observational-type studies), the management of randomized controlled clinical trials (RCT) is very difficult and as such, conducting a systematic review (SR) based on RCT and realice a meta-analysis is even more difficult. Therefore, we have generated a methodology for implementing a SR with different types of designs (including observational studies) as an alternative in order to clarify the uncertainty in the field of therapy when there are few RCT and the evidence relies so heavily on descriptive and observational studies. The aim of this study, was to set out a methodology that leads to a SR with various types of...

Autores: Villanueva,Pía; Quevedo,Mónica; de Barbieri,Zulema; Piñeiro,Soledad; Herrero,Carolina; Fernández,María Angélica; Palomino,Hernán.
Chilean Robinson Crusoe Island is a semi-isolated location with unusually high rates of both consanguinity and language disorder. The current population of 633 inhabitants is descended almost exclusively from the colonization at the end of the 19th century, as there were few preceding immigrations to the island. This study investigates the genetic composition and degree of miscegenation within the island population, using dental morphological markers. The universe of island children was studied (n= 128, 3 to 15 years of age) using clinical exams, dental cast, and identification of each individual within a previously-constructed extensive genealogy for the island. The frequencies for Carabelli's cusp (61.7%), shovel-shaped incisor (9.4%), and sixth cusp...

Evaluation of Cephalic Indices: A Clue for Racial and Sex Diversity
Provedor de dados: 77
Autores: Ilayperuma,Isurani.
Cephalic index is an important parameter in evaluating racial and gender differences. A large body of evidence shows a clear racial variation in cephalic index. Therefore detailed knowledge of the population specific data on biometric features of the cranium is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its' significance, little is known concerning the cranial morphometry in Sri Lankans. Hence, the present study was undertaken to establish the cranial indices and head shapes in an adult Sri Lankan population. A total of 400 subjects with an age span of 20-23 years were...

Study of Wool Characteristics in the Aranese Ovine Breed
Provedor de dados: 77
Autores: Parés,P.M; Jordana,J; Pérezgrovas,R.
To date, no ethnological study on the wool characteristics of the Spanish Aranese ovine breed has been published. Fifty three animals belonging to this breed are tested as fleece samples. Each sample is analyzed for fleece type and length, yield by isoalcohol scouring, fiber length for each kind of fiber, variation in fiber diameter, and proportions of non-medullated and medullated or kemp fibers. Fiber length appears shorter than that previously reported for the breed by other authors. Fleeces of the Aranese sheep breed can be described as square, simple, "semi-open" and short with a relatively high yield by isoalcohol scouring and low medullation levels, thus indicating good potential quality and greater suitability for potential processing than other...

Morphometric Analysis of Mice Testicular Tubules after Administration of Malathion and Maca
Provedor de dados: 77
Autores: Bustos-Obregón,Eduardo; del Río,Fernando Costa; Sarabia,Luis.
Organophosphoric (OP) agropesticidas are amply used to increase food production. However, it has been verified that they induce alterations at testicular level related to the diminution of fertility in humans as in animals. On the other hand, different studies have been made to develop chemical or natural compounds that can induce an antagonistic effect to OP. In previous studies an extract from a plant, from the Peruvian Andes (Maca) has been recognized by its stimulating action on spermatogenesis. In the present study the effects of both external agents were evaluated on testicular sections of testis of adult male mice on a population of 52 mice CF1, divided at random in 4 groups (Control, Malathion, Maca, Malathion-Maca), with sacrifice intervals of...

Provedor de dados: 77
Autores: Sharma,D. K; Sharma,Vandana.
The Simian and Sydney creases are variant palmar creases which have now drawn medical attention as their presence correlates strongly with numerous chromosomal anomalies and diseases. Works on these creases have been done on several human communities, racial and ethnic but no specific study is focussed out on the Indian populations. In this study 1000 Central Indian subjects (500 males and 500 females) aged between 5 to 70 years were randomly selected and examined by the authors. We found the prevalence of Simian, Sydney and Suwon creases in studied population of Central India is 14.4%, 3.6% and 2.4% respectively, which is a little higher than the figures for Asians and Caucasians claimed by earlier studies. There is no any association between these...

Provedor de dados: 77
Autores: Oosthuizen,Maria Aletta; Pretorius,Etheresia; Oberholzer,Hester Magdalena; van der Spuy,Wendy Jeannette.
Engineered nanoparticles are designed to perform specific functions and therefore have specific properties that could potentially be harmful. Nanoparticles such as titanium dioxide have the potential to become transparent and are therefore widely used in cosmetic products and sunscreen. Research on the toxicity of nanoparticles is of utmost importance and numerous in vitro studies have shown that some of these particles could have adverse health effects. The current study aimed to investigate the in vivo effects of two different titanium nanoparticles at two different concentrations after inhalation by experimental BALB/c mice. This was done to determine whether these particles will cause an inflammatory reaction, visible as alterations in platelet and...

Prevalence of Vertical Condilar Asymmetry of the Temporomandibular Joint in Patients with Signs and Symptoms of Temporomandibular Disorders
Provedor de dados: 77
Autores: Iturriaga,Verónica; Navarro,Pablo; Cantin,Mario; Fuentes,Ramón.
Vertical condylar asymmetry (VCA) is considered a risk factor for the development of a temporomandibular disorder (TMD). VCA is determined by comparing the vertical condylar height between the left and right condyle. Several techniques have been developed to evaluate this asymmetry, and the most common among them are developed by Kjellberg et al. (1994) and Habets et al. (1988). The objective of this study was to evaluate the similarity of the Habets' and Kjellberg's methods with regard to these results and analyze the VCA results of the temporomandibular joint in patients with signs and symptoms of TMD. We analyzed 48 patients between 12 and 65 years of age. In each patient, the percentage of condylar symmetry according to the Kjellberg's and Habets'...

Autores: Sethi,Ashwani; Chopra,Shamit; Passey,J. C; Agarwal,A. K.
Intraparotid facial nerve neurofibromas are a rare entity, and are grossly and histopathologically distinct from the comparatively more prevalent schwannomas. We report a rare case of an intraparotid facial nerve neurofibroma with intratemporal extension in a 48-year-old female. The tumor was surgically excised with cable grafting of the facial nerve. Electroneurography may eventually assist in the preoperative diagnosis. Facial nerve resection should be more readily contemplated in a patient with neurofibroma than in a patient with schwannoma; however, facial nerve preservation with serial follow-up electroneurography and computerized tomography remains a viable option in patients with small facial nerve neurofibromas when electrical testing reveals...

Skin serves as interface between inner aand outer environment, and acts a a mechanical barrier. Changes in its characteristics may lead to a higher pathogenicity, less defense capacity, or both. Diabetes mellitus is a heterogeneous group of chronic hyperglycemic disorders, considered a syndrome rather than a simple disease. Complications by diabetes are mostly associated with the chronicity of the disease and very little information exists about its early pathological processes. Animal models are considered very useful for the study of early diabetes. Wistar rats with lloxan induccced diabetes were used in a way to study the progresive effects of diabetes mellitus on the skin epithelium. Five animals were sacrificed at 7 days (Phase I) and five others at...

Breast cancer mortality has been increasing in Arica Chile where it has surpassed the national rates 11 times between 1990 and 2010. The city of Arica was sprayed with the organophosphrous pesticide malathion in order to control the Mediterranean fly 33 years ago. Moreover we have demonstrated that a malathion treatment induces the formation of breast carcinomas in Sprague Dowley female rats. The objective of this work was to find a relationship between malathion aerial spraying and the increased mortality rate due to breast cancer that has been observed in Arica in recent years. We extracted city data bases with all breast cancer cases diagnosed from 1995 to 2005 from the Dr. Juan Noe Crevani Hospital of Arica city and Ernesto Torres Hospital of Iquique....

Provedor de dados: 77
Autores: Fernandes,Rodrigo M. P; Lazzoli,José K; Manaia,Jorge H. M; Babinski,Marcio A.
The superior gemellus muscle (SGM) normally arises from the outer surface of the spine of the ischium, blends with the upper part of the tendon of the obturator internus, and is inserted with it into the medial surface of the greater trochanter. In this paper, we describe an anatomical variation in which the SGM is absent bilaterally. Therefore, as there are not many cases in literature, our attention has been drawn to the importance about absence of SGM, in order to improve anatomical and clinical knowledge about this finding.

Autores: Ibrahim,Abdullahi Ali; Aliyu,Jibril; Ashiru,Rabi Muhammad; Jamilu,Mustapha.
A comparative study of testicular biometry was done in rams using three major breeds of sheep in Nigeria. Biometrical parameters observed were scrotal circumference (SC), testes weight (TW), testes length (TL), tunica albuginea weight (TAW), testes volume (TV), testes density (TD), epididymal weight (EW), epididymal length (EL), caput (CA), corpus (CO), cauda weight (CU), epididymal volume (EV) and epididymal density (ED). The results showed significant differences (p&lt;0.05) between the Uda, Balami and Yankasa breed in the SC, TW, TV, EW, EL, CA, CO, CU, and EV. The Uda had significantly higher (p&lt;0.05) values in most of the parameters examined than the two other breeds. A bilateral symmetry was observed for Uda and Balami in testes weight and testes...

Autores: Potu,Bhagath Kumar; Gorantla,Vasavi Rakesh; Pulakunta,Thejodhar; Rao,M. S; Mamatha,T; Vollala,Venkata Ramana; Nayak,S. R.
During the laboratory dissection of the fore arm, an accessory head of flexor pollicis longus muscle has been observed unilaterally in the right upper limb of a male cadaver. It took its origin from the under surface of flexor digitorum superficialis muscle just distal to the origin of this muscle from medial epicondyle. On further dissection we have noticed that, the accessory belly was running downwards to the medial aspect of the tendon of flexor pollicis longus muscle for its insertion. Its possible role in anterior interosseous syndrome is discussed in detail with a brief review

Provedor de dados: 77
Autores: Oporto V,Gonzalo H; Saavedra,Rubén; Soto P,Camila C; Fuentes,Ramón.
Abnormal interaction between oral epithelium and underlying mesenchematic tissue during odontogenesis could result in teeth with an anatomical variation. First maxilar premolar has such variable root canal morphology. However, (0.2-6% of cases) a three-rooted premolar is particularly uncommon. First mandibular premolar frequently has one root and one single canal (75% of cases), however, a tooth with two canals and two separate roots could be found (19.5-22.5%). Execution of an accurate diagnosis of root canal system is essential to perform a successful endodontic treatment and tooth rehabilitation. This article describes diagnosis, endodontic treatment and rehabilitation (means single crown) of a maxillary three-rooted and three-canal first premolar, and...

Easy and Unbiased Determination of the Maxillary Sinus Volume
Provedor de dados: 77
Autores: Coronado,Cesar; Arriagada,Oscar; Suazo Galdames,Iván.
Determining the volume of the maxillary sinus is necessary in certain procedures. We present a simple method for estimating the volume of the maxillary sinus from groups 3, 5 and 9 coronal CT scan using the Cavalieri method combined with systematic sampling and evaluated randomized images. We used 10 dry skulls submitted to the TC. The actual volume was determined using silicone adapted to the maxillary sinus cavity. The estimated volume showed a high correlation with real volume, with no differences between groups. We concluded that it is possible to estimate without bias and with high accuracy the volume of the maxillary sinus from a minimum of 3 CT images obtained through randomized systematic sampling and the proposed method.

The skeletal muscle fascia corresponds to a condensation of connective tissue. Fascias are highly innervated and sensitive, and can cover non-expandable structures as well as musculature. It is suggested that fascias have a pivotal role in functions such as postural regulation, peripheral motor coordination and proprioception. Also, the presence of inflammation and microcalcification in fascia of patients with localized muscle pain has been described, suggesting a pathogenic role in pain. The aim was to describe the histological structure of the external deep fascia of the trapezius muscle, with emphasis on the content and arrangement of muscle fibers, type I collagen, and adipose tissue. Sample material was obtained from a male cadaver (60-70 years old),...

What is Published in Human Morphology?: Types of Designs and Levels of Evidence
Provedor de dados: 77
Autores: Suazo Galdames,Iván; Manterola D,Carlos.
Evidence-based medicine (EBM) employs the best available evidence in a particular time and context to solve specific clinical problems. This method of practicing medicine has been adopted by most of the disciplines involved in medical training; however, morphology appears to remain beyond this paradigm. The first step in evidence-based practice based on morphology is to recognize the types of studies being conducted with regard to morphology, followed by the assessment of the level of evidence that they provide, which is the purpose of this study. We designed a bibliometric study, in which journals in the Master Journal List of Thomson Reuters, selected using the keywords "Morphology" or "Anatomy," available between 2007 and 2008, with access to full text...

Anthropometric methods used to estimate muscle mass (MM) do not specify values for body segments, a critical fact for individuals practicing physical activities or clinical diagnosis. In this study, 60 recreational athletes are anthropometrically evaluated and also undergo dual energy X-ray absorptiometry. Linear regression statistics is subsequently used to establish the constants allowing the obtaining of the segment MM. Three equations were obtained, one for the upper members: MMUL = (0.533*FAP) - (0.176*RAP) + (0.42*WP) + (0.282*SRL) - 19,985; a second equation for muscle mass of the lower members: MMLL = (0.186*H) - (0.158*LTTL) - (0.024*LTL) + (0451*LP) ­ 24.535; and the third one for the muscle mass of the trunk TrMM = (0.026*W) + (0.046*H) +...

Femoral Functional Adaptation: A Comparison Between Hunter Gatherers and Farmers Using Geometric Morphometrics
Provedor de dados: 77
Autores: Püschel,Thomas A; Benítez,Hugo A.
The transition from hunting and gathering to agriculture has been associated with a gracilization in human form, especially in long bones. This has been interpreted as result of an increasingly sedentary lifestyle and reduced workload in the farming populations. However the majority of these evidences have been based on the application of different biomechanical techniques or the qualitative assessment of distinct morphological traits on attachment sites. Hence, this study tried to address whether is possible to distinguish between two different populations (hunter-gatherers and farmers) by quantifying their femoral morphology applying geometric morphometrics. We compared 16 male left femora belonging to two populations of Native Americans from the same...

Autores: Cuadrado,G. A; Andrade,M. F. C; Akamatsu,F. E; Jacomo,A. L.
The surgical treatment of breast cancer has been enhanced throughout the years in order to offer oncologically safer and more effective results with lower esthetic impact and fewer sequelae. The lymphedema of the upper limb is still an iatrogenic result of great incidence and morbidity after this treatment. A possible existence of independent breast and upper limb lymphatic pathways has become the issue of many researchers willing to minimize its occurrence. This review aims to compare the lymphatic pathways in the axilla described by traditional anatomy books and recently published articles about Axillary Reverse Mapping (ARM). With this purpose, a comparative table was made with the descriptions found in books and articles, a statistic table of the data...

Autores: Olukole,Samuel Gbadebo; Adeagbo,Mojibola Abosede; Oke,Bankole Olusiji.
The histology and histochemistry of the adrenal gland of the African giant rat, AGR (Cricetomys gambianus Waterhouse) was carried out using ten adult male rats with the knowledge of providing information which could be helpful in an improved knowledge of the structure and function of the gland. The adrenal gland of the African giant rat has a distinct cortex and medulla surrounded by a thin rim of capsule. The adrenal cortex has three zones which are basically the zona glomerulosa, zona fasiculata and zona reticularis with the absence of zona intermedia. The zona glomerulosa contains polyhedral cells which form irregular clusters or cords while the zona fasiculata had radial cells of cuboidal or polyhedral shape. The cells of zona reticularis are similar...

On the Prediction of Personal Stature from Cranial Dimensions
Provedor de dados: 77
Autores: Ilayperuma,Isurani.
Dimensional relationship between body segments and stature has been the focus of scientists for many years. All such studies were based on the fact that body segments exhibit consistent ratios relative to the stature and these ratios are linked to age, gender and race. Racial characters are best defined in the skull. Therefore, prediction of stature from cranial remains is vital in establishing the identity of an unknown individual. Despite its significance, little is known concerning the cranial dimensions in Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression model between the cranial dimensions and height of an individual. A total of 400 subjects with an age span of 20-23...

Report on a Sheet Plastination Technique using Commercial Epoxy Resin
Provedor de dados: 77
Autores: Ottone,Nicolás Ernesto; del Sol,Mariano; Fuentes,Ramón.
Plastination is a conservation technique which allows anatomical pieces to be preserved, dry and odor-free, for an indefinite period. In particular, plastination of sections of tissue with epoxy resin allows very thin slices to be made of various regions of the anatomy, permitting close viewing of anatomical structures which are difficult to access by dissection or cadaver exploration. The objective of this work is to present a plastination technique developed in our laboratory for tissue sections using commercial epoxy resin, as an alternative to the existing classic plastination techniques. The technique was applied to a human knee, obtaining 5 mm thick sections which were compared with computerized tomography images. The development of an alternative...

Rare Case of Bilateral Gemination in Deciduous Teeth
Provedor de dados: 77
Autores: Barbério,Gabriel Salles; da Costa,Soraia Veloso; Rios,Daniela; de Oliveira,Thais Marchini; Machado,Maria Aparecida de Andrade Moreira.
Gemination in bilateral mandibular primary teeth is a rare anomaly. This kind of anomaly features two crowns totally or partially separated, but only one root and one root canal. At intraoral clinical examination of children we found different anatomy of mandibular primary canines with two partially separated crowns. The radiographic exams showed geminated teeth. After 3-years of follow-up, the cone beam computed tomography showed the absence of the mandibular permanent lateral incisors and the aspect of normality of the permanent canines germs. Although the gemination in primary teeth itself is considered as a harmless anomaly, its presence could indicate the occurrence of some dental anomaly in the permanent dentition. To the best of our knowledge, this...

GII ­ 30 and GIII ­ 60 days, after mandibular molar extraction, with three experimental animals and one control per group. Qualitatively, ultrastructural changes of protein filaments from myofibrils of these muscles and ipsilateral to the extractions were observed. Ultrastructure asymmetry and disorganization of Z line and I band, in the experimental group GII, of Medial Pterigoid muscle (MPT) were observed. The temporomandibular dysfunction, stimulated by the unilateral extractions of mandibular molars in rats may lead to modifications in the Z line and I band, which showed to be sensitive to this dysfunction. Changes in the MPT muscle, probably related to...

The communications between the branches of cervical plexus and cervical branch of facial nerve are common and are well known. However, this communication usually occurs between the transverse cervical nerve and cervical branch of facial nerve. During routine dissection classes for the Medical undergraduate students, we came across an anatomical variant of anterior division of great auricular nerve. This variation was found in a 60-year-old male cadaver of South Indian origin and it was unilateral. The great auricular nerve arose from the loop of ventral rami of C2 and C3 spinal nerves and divided into anterior and posterior branches. The anterior branch ran obliquely upwards and forwards on the surface of the sternocleidomastoid muscle along with the...

Autores: Bustos-Obregón,Eduardo; Esponda,Pedro; Sarabia,Luis.
The spermatogenesis is regulated by the hypotalamus-hypophysis gonadal axis, and the androgens play a fundamental role in their last stages. The administration of the antiandrogen flutamide interferes with the function of androgen dependent organs (Prostate (P) and Seminal Vesicle (VS)). In this study flutamide (10mg/Kg b.w.) was injected to 10 mice and vehicle to the controls (n=6). The mice were sacrificed at 24 (n=5) and 72 (n=5) hours. In testicular sections the tubular diameter (TD) and height of seminiferous epithelium (EH) were measured. P and VS were macerated, and concentrations of fructose (VS) and zinc (P) were determined. No significant difference exists in the DT among the groups. However, the 72 hrs group showed EH higher than the control (p...

Chondrogenic Differentiation of Bone Marrow Mesenchymal Stem Cells: First Successful Latin-American Report
Provedor de dados: 77
Autores: Mardones,Rodrigo; Martínez,Rafael; Paredes,María Jose; Zalaquett,Eugenio.
Osteoarthritis is the more frequent cause of disability in adult people and it is associated to cartilage degeneration of affected joints. This cartilage has a limited ability to repair. Several treatments have been tested including the use of Mesenchymal Stem Cells. These cells are an attractive source for cartilage repair because of their availability to chodrogenic differentiation by progressing sequentially through the expression of cartilage specific extracelullar matrix molecules, as in the embryologic human development. The aim is to obtain, culture and differentiate rabbit Bone Marrow derived Mesenchymal Stem Cells in vitro to chondral lineage. By differential centrifugation the mononuclear cell level was obtained from rabbit bone marrow samples....

AGEING INDUCES APOPTOSIS AND INCREASES HSP70 STRESS PROTEIN IN THE EPIDIDYMIS OF Octodon degus
Provedor de dados: 77
Autores: Bustos-Obregón,Eduardo; Esponda,Pedro.
Apoptosis has been largely analyzed in the testis. Nevertheless, the epididymis has been scarcely studied. We analyzed the number of apoptotic cells in the different regions (caput, corpus and cauda) of the epididymis of the South American rodent Octodon degus both young and senile. Apoptosis was identified using the TUNEL method which detects in situ DNA fragmentation. Apoptosis was detected in the principal cells of the epididymal epithelium. The caput epididymis was the region more affected. The caput of young animals showed that 0.32/1000 cells were apoptotic in contrast to 5.1/1000 of senile animals. Also in the cauda epididymis apoptosis is increased with age, appearing 0.14/1000 and 3.9/1000 in young and senile animals, respectively. On the other...

Autores: Sarabia,L; Espinoza-Navarro,O; Maurer,I; Ponce,C; Bustos-Obregón,E.
Since normal sperm parameters can be altered by organophosphorous pesticides, this study intended to determine if melatonin is able to prevent the damage on sperm quality after an acute exposure to diazinon. Adult male mice were injected intraperitoneally with melatonin, diazinon (1/3 or 2/3 LD50) or both, and sperm parameters were evaluated on days 1 or 32 post injection. Groups treated with diazinon showed elevated lipid peroxidation levels on day 1 post treatment, while groups pretreated with melatonin before diazinon showed no difference compared to control. Sperm count showed a significant decrease in both diazinon-treated groups only on day 32 post injection; no differences were observed in groups pretreated with melatonin prior to diazinon compared...

Cleidocranial Dysplasia: A Case Report
Provedor de dados: 77
Autores: Alves,Nilton; Oliveira,Reinaldo de.
The cleidocranial dysplasia is a rare disease which can occur either spontaneously or by a dominant autosomal inheritance, with no predilection of genre or ethnic group. The odontologist is, most of the times, the first professional who patients look for to solve the problem, since there is a delay in the eruption and /or an absence of permanent teeth. In the case related in this work, this was the reason why the patient looked for treatment. Many others odontological problems are also present in this syndrome, such as, supernumerary teeth, retained teeth, with shape deviation and absence of deciduous teeth resorption. The premature diagnosis allows a proper orientation for the treatment, offering a better life quality for the patient.

Transfection of Gametes: A Method to Generate Transgenic Animals
Provedor de dados: 77
Autores: Esponda,Pedro.
The production of transgenic animals (TA) using transfected spermatozoa or eggs is commented. Different methods have been employed to introduce transgenes into the gametes of several vertebrates and invertebrates. Methods for the transfection of gametes have employed naked DNA, viral vectors, DNA/Liposome complexes, electroporation or high velocity microprojectiles. Spermatozoa and oocytes or eggs have showed a good transfection efficience (80% in some cases), and microscopical observations demonstrated that the transgenes appeared localized in the nucleus. Gametes have shown to be naturally protected against the entrance of foreign genes because some semino plasma or plasma membrane proteins block the entrance of foreign genes in spermatozoa. In the...

Autores: Namm,Aimar; Arend,Andres; Aunapuu,Marina.
The role of bone morphogenetic proteins (BMP-s) in the development of the nervous system has been widely studied on avian and rodent embryos. Human embryos have rarely been available for detection of BMP expression. In this study 39 human embryos of Carnegie stages (CS) 10-20 were investigated. The embryos were fixed in paraformaldehyde, embedded in paraffin and sectioned serially in transverse direction. BMP-2 and BMP-4 protein expression in the developing neural tube and the caudal spinal cord was determined by immunohistochemistry. Our data show that BMP-s tend to be more expressed in the neural tube in earlier stages; in particular, BMP-4 staining was found to be higher at CS10 compared to CS20. More detailed analysis was performed on embryos of...

During routine dissection in the Department of Anatomy following anatomical variations of phrenic nerve were observed on right side in the neck region of a middle aged cadaver. The phrenic nerve in its early course close to its origin was giving a communicating branch to C5 root of brachial plexus and at the level of the root of neck just before entering the thorax, the phrenic nerve was placed anterior to the subclavian vein. This unique case of phrenic nerve variation gains tremendous importance in context of subclavian vein cannulation, implanted venous access portals, and supraclavicular nerve block for regional anesthesia

Provedor de dados: 77
Autores: Smok S,Carolina; Rojas R,Mariana.
Ovogenesis and foliculogenesis in the mare differ from other farm animals and therefore, gamete manipulation, in vitro fertilization and embryo transfer have been very difficult. The histologic traits of ovaries from 12 mares, in estrus and diestrus were studied. Number and size of follicules and corpora lutea were recorded. The ovarian stroma was evaluated using the pricosirius technique for collagen. A simple morphometric analysis was done using computerized scanner programs. During late estrus, one dominant follicle (46 ± 4mm) is seen. The surrounding stroma contains collagen I and III. By the end of the estrus, one hemorrhagic follicle is seen, plus one or two small follicle (2 mm in size). In early diestrus there is a corpus luteum (43-60 mm) and some...

Autores: Yeri,Luis A; Gómez,Jorge E; Fontaneto,Sergio; Espósito,Marcia.
The aortic arch branches variations have called the attention of several authors, who have handled studies and classifications, both human and in different animals. The common trunk, which is between the brachiocephalic trunk and the common left carotid artery, is the most common variation. We conducted a descriptive and randomized study of the presence of the trunk mentioned before, trying to establish the possible relationship between this variation and the distribution plates of atheroma. The lumen observation makes it possible to define and check the distribution of the ostium, among the common ostium and the ones with common trunks. Regarding the plates of atheroma, it was found that there is a slight prevalence in common trunks cases, with respect to...

Autores: Reis,Francisco Prado; Aragão,José Aderval; Moura,Gustavo Souza; de Santana,Iúri Amorim; Carvalho,Eric Allan Nunes; Feitosa,Vera Lúcia Corrêa; Nunes,Marco Antonio Prado.
We dissected the shoulders of 20 human foetuses to anatomical study. The purpose of this study was to characterize the anatomical origin of the long head tendon of the muscle biceps brachii (LHBBT) in human foetuses and its relationships with the glenoid labrum of the scapula. The results had shown that in approximately 95% of the cases the tendon of the long head of the biceps brachii inserts in the region of the glenoid labrum. This origin seems to form, together with the glenoid labrum, an anatomical complex. We conclude that the almost totality of the LHBBT was originated in the glenoidal labrum. For us, this furthermore reinforce the importance and necessity of better clarifying the anatomical and clinical implications of the biceps/labrum complex.

El cadmio (Cd), presente en el aire, agua potable y alimentos, tiene potencial para afectar la salud humana, principalmente en las regiones altamente industrializadas. El Cd además de afectar la función placentaria, puede atravesar la barrera placentaria y perjudicar directamente el desarrollo fetal. En virtud de que el organismo es particularmente susceptible a la exposición al Cd durante el período perinatal, y que ese metal puede ser excretado en la leche, el objetivo del presente trabajo fue estudiar los efectos de la exposición continua a agua potable conteniendo bajos niveles de Cd durante la lactancia sobre las glándulas salivales de la rata. Ratas hembra recibieron agua potable conteniendo 300mg/l de CdCl2 ad libitum durante toda la lactancia....

Morphologic Effects of Filiform Papilla Root on the Lingual Mechanical Functions of Chinese Yellow Cattle
Provedor de dados: 77
Autores: Fu,Jun; Qian,Zhihui; Ren,Luquan.
The morphology of filiform papilla root in the tongue of Chinese yellow cattle were studied by scanning electron microscopy, and several geometric models were established to analyze the possible effects of such structures on lingual mechanical functions. Conical and tongue-like filiform papillae were detected in different locations on the lingual surface, along with six types of root structures. A lingual groove surrounded the papillae in five of these structures. To date, such grooves have not been discussed in studies on bovine lingual morphology, and those distributed on the dorsal surface of the lingual apex can limit the motion ranges of filiform papillae. Two secondary papillae emerged from a groove on the dorsal surface of the lingual apex's caudal...

This study reports tympanic cavity (TC) volume in newborns, which was missing in the literature. Ex vivo histology and computerized tomography (CT) scans were performed on temporal bone and data were analyzed in part using software developed in house. CT images with a slice thickness of 0.5 mm were obtained from 5 newborn cadavers and analyzed independently by two expert researchers. The border of the TC was delineated manually and measurement of area of interest was calculated on masked images. Then, the area measurements from all sections were added to estimate the total volume. The agreements between the histological and CT findings were then compared for accuracy, repeatability and reliability. The Dice and Jaccard similarity coefficient measures were...

Modularidad e Integración Morfológica en Cráneos Humanos: un Enfoque Morfométrico Geométrico
Provedor de dados: 77
Autores: Püschel,Thomas.
Los conceptos de integración y modularidad refieren al grado de covariación entre los componentes de una estructura. Los módulos morfológicos son aquellas estructuras que poseen componentes que covarían fuertemente, pero que a su vez son relativamente independientes de otros módulos. Mientras que por integración morfológica se entiende a la variación morfológica coordinada de los componentes de un todo funcional. En el caso del cráneo se han definido tradicionalmente dos módulos en base a su origen embrionario diferencial: el esplacnocráneo y el neurocráneo. Se ha sugerido que el desarrollo cráneofacial es altamente integrado, tanto funcional como ontogénicamente. Se puso a prueba la hipótesis de modularidad del desarrollo del cráneo en base a orígenes...

The adrenal gland is an important endocrine organ in vertebratesthat produces a wide variety of hormones. The anatomical results showed that the adrenal gland in Bactrian camel had a typical blood supply and innervation. Surprisingly, we found that there was a novel connection mainly consisted of fibrous tissue, blood vessels and nerve bundles between the adrenal gland and the kidney in Bactrian camel, and we named it fibrous tissue-blood vessels-nerve bundles (FBN bundle). To the best of our knowledge, this FBN bundle was the first reported in Bactrian camel, and not yet observed in other animals. While, its functions and mechanisms should be studied further. We speculated that a direct function of this novel path might be to strengthen the communication...

La hernia femoral se forma cuando un divertículo peritoneal pasa a través del anillo femoral. Es más frecuente en mujeres que en hombres y en el lado derecho. La literatura es controvertida sobre la forma del anillo femoral quirúrgico, y se omiten sus dimensiones. Por otro lado, no existen explicaciones de naturaleza fisiológica o anatómica que justifiquen la mayor incidencia de la hernia femoral en el lado derecho. Buscando determinar la forma más frecuente del anillo femoral quirúrgico y sus dimensiones, como también esclarecer por qué ocurren más hernias femorales en el lado derecho, realizamos disecciones en 25 cadáveres adultos del sexo masculino. Fueron encontrados anillos en forma de trapecio en el 48% de los casos, de forma triangular en el 44% y...

Autores: Duque Parra,Jorge Eduardo; Barco Ríos,John; Mendoza Zuluaga,Julián.
Dorello´s canal is an eponym term referring to a small fibro osseous landmark, by way of arc, located at the apex of the petrous temporal region and for which the nerve abducens passes before reaching the cavernous sinus. This landmark is not referenced in Terminologia Anatomica, even as a variable structure. We selected 74 adult dry skulls and six heads fixed in formalin 10 % without classifying them by ethnicity or gender. As inclusion criteria, we selected those where the middle cranial fossa and the apex of the petrous temporal region were in good condition. Fifty seven (57) skulls (83, 82 %) showed the presence of canal bilaterally; 4 (5.89 %) showed it unilaterally to the right; 4 (5,89 %) were unilaterally at the left and 3 (4,41 %) had no canal....

Anatomy is the science that studies the body and a basic discipline in health and biological sciences indispensable to students that study this area, and plays a important role in the comparison of species. Nowadays anatomy is falling into academic and scientific crisis. Recently, the number of papers and reviews on health science education have increased considerably. Pre-clinical disciplines are essential for all health and biological science courses; among them anatomy is considered to be the basis of morphological sciences. For that reason, throughout history, this discipline has been viewed as a factual knowledge base that must be learned in its entirety. History of anatomy demonstrated that teaching in this area is facilitated by the use of...

Movements at the human shoulder girdle are the result of complex interplay of glenohumeral, acromioclavicular, sternoclavicular and scapulothoracic articulations. Clavicle apart from articulating with the scapula and sternum is also connected with first rib by costoclavicular ligament and with coracoid process by coracoclavicular ligament. At times the area of attachment of these ligaments on clavicle, first rib and scapula show faceted apophysis suggesting the presence of additional diarthrodial articulations. Costoclavicular joint exists between clavicle and first rib and coracoclavicular joint between clavicle and coracoids process. Both these joints are described in the literature, but the concurrent occurrence of them in the same bone has not been...

Autores: Chanasong,Rachanee; Putiwat,Phongpitak; Roboon,Jureepon; Sakulsak,Natthiya.
An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the Department of Anatomy, Faculty of Medical...

Provedor de dados: 77
Autores: Olatunji-Akioye,A. O; Adeyemo,O. K.
The correlation between chest girth and weight of sheep and goats have been studied as a predictive guide in homestead farms where equipment to definitively quantify the weight of animals are unavailable and inaccessible. The livestock markets in the South Western part of Nigeria are still very underdeveloped and consist of peasant farmers taking their few animals to more developed areas to offer them for better prices to the consumer or middle men who are in the trade to attain the best profit. Twenty each of sheep and goats were randomly selected in herds from three different commercial locations and evaluated using weight and chest girth measurements as indices. Mean weight for the 3 groups of sheep was between 19.8 and 31.15kg, while for the 3 groups...

Twenty-eight skeletonized hemicoxae from young animals (yearlings, 13 males and 15 females) belonging to the "Cavall Pirinenc Català" horse (Catalan Pyrenean Horse) breed were studied by means of geometric morphometric (GM) methods. Morphometric analysis was based on coordinates of 16 landmarks of the ilium and ischiopubic regions that were digitized on 2D photographic images. Sexes did not appear separated either by size or shape, the latter being independent of the former. K-means clustering of shape variables were used in order to classify individuals by sex and an average accuracy of 57.1% was achieved. Males were misclassified more frequently than females. For the iliac landmarks, which contributed to the total variance of shape with the higher...

The aim of our research was to create an osteogenic unit in the skulls of athymic mice; however, the first challenge we faced was to find sufficient and adequate data that would allow us to determine the morphological, immunohistochemical and microtopographical characteristics that could be used as normality standards in athymic mice skulls and, hence, a reference in the event of achieving the formation of de novo bone using the osteogenic unit we proposed. Knowing the normal bone morphology in the skull of athymic mice was a necessary precondition to develop subsequently an osteogenic unit possessing the Osteogenesis, Osteoinduction and Osteoconductivity that could be compared versus those in the normal bone during its formations and remodeling processes....

Autores: Ferreira-Medeiros,Mildred; Correa-Gillieron,Elenice.
Lectins are proteins with binding sites that recognize a specific sequence of sugar moieties in complex glycoconjugates. In the present study the tomato lectin ­ Lycopersicon esculentum (LEL) (a selective microglial and endothelial marker) has been reported to recognize specific residues of N-acetylglucosamine (GlyNAc) and poly-N-acetyllactosamine. In the pineal gland the biotinylated LEL was used to investigate the appearance of these sugar residues in the structures of the rats during their development and adult life. Our results showed that the binding of LEL occurred exclusively in the material adherents on surface of the endothelia of the vessels in the peripheral and central regions of the gland. An exception can be cited to rats in first postnatal...

The extracellular matrix is a key element in the tracheal morphology and physiology, both in normal and pathological states, yet little is known regarding its composition and organization. Herein we carried out a detailed study of the morphological organization and volumetric density of elastic system fibers in the trachea of Wistar rats. Six Wistar rats at the age of 45 days were used. The trachea was excised following anesthesia with Thiopental and perfusion through the left ventricle with buffered saline followed by formalin solution. Samples were fixed in formaline, embedded in paraffin, and histologically processed. The elastic system fibers were evaluated at light microscopy by using Weigert's resorcin-fuchsin technique after oxidation with oxone....

Dens evaginatus in Hemophilic Patient: A Case Report
Provedor de dados: 77
Autores: Borie E,Eduardo; Oporto V,Gonzalo; Aracena R,Daniel.
Tooth development occurs through the interaction between oral tissues during embryogenesis. Alteration through odontogenesis may cause tooth morphological alterations, one of these could be Dens evaginatus. This anatomical variation could be originated from an abnormal proliferation and folding of a portion of the inner enamel epithelium and subjacent ectomesenchymal cells of the dental papilla into the stellate reticulum of the enamel organ during the bell stage of tooth formation. Dens evaginatus is defined as a tubercle, or supplemental solid elevation on some portion of the crown surface. Inadequate clinical management of these teeth may result in a pulpal exposure and possible loss of vitality of the tooth. The research wants to report a case of Dens...

Many of the anatomical variations that are inadequately described or quantified are actually more clinically and surgically significant than being just anatomical curiosities. We report about such a variation where an aberrant slip existed in the scalene group, in a 56 year old embalmed female cadáver. This kind of variation may affect the size of the scalene triangle, and thus, may potentially result in varied signs and symptoms in patients vulnerable to thoracic outlet syndrome (TOS). Proximity of the scalene muscles to the brachial plexus, subclavian artery and vein, coexisting with aberrant slips or bundles may also predispose to compression syndromes.

Among the present`s sesamoids in the human body, the fabella can be found in the posterior part of the knee in low incidence. This report is quite controverted in the classic anatomical literature as well as its constitution. Its fixation is on the tendon of the gastrocnemius lateralis, close to its origin, in the posterior part of condilus femuralis lateralis. However, when its occurs, generally induces in the knee the absence of arcuate ligament with the presence of fabellofibular ligament. The prevalence is larger in male individuals. Few studies discuss the histology of the fabella. Some authors suggest that the fabella basically formed by bone tissue and others describe it as a fibrocartilaginous.

Provedor de dados: 77
Autores: Alvarez,M; Urbina,G; Perdomo,L.
In the field of studies of acute toxicity induced by bacterial agents, Shiga toxins have been relevant due to the severity of the extra-intestinal diseases they cause. Numerous studies have shown that Shiga toxin induced apoptosis in different cell types; however, this important process has been little studied in vivo experimental models. In this study, the effects of excretion products of Shigella dysenteriae, in which Shiga toxin is present, were investigated on early larval stages of Zebrafish, an animal model with many advantages over other in vivo experimental models traditionally used. Both the collection of eggs and larvae of Zebrafish, and the product from excretion from Shigella dysenteriae (SdyEP) were performed according to laboratory standards....

Provedor de dados: 77
Autores: Sumayya,; Faruqi,Nafis A; Ansari,Mohd Salahuddin; Ghaus,Farah.
Lumbosacral part of the spinal canal requires special attention because this is the site commonly involved in spina bifida, tethered cord syndrome and some other pathologies like fatty tumours in the spine, cysts and syrinxes. The diagnosis as well as the treatment of neural tube defects mandates an accurate knowledge of morphometry of lumbosacral vertebral canal. There are various reports on radiological morphometric measurements in human foetuses by various authors but these possess inherent variability due to imaging techniques, patient positioning, observer's measuring techniques and normal and pathological variations. To overcome all these limitations, direct measurements by vernier calliper were preferred. 30 Formalin preserved human foetuses, of all...

Autores: Chodewaratham,Pathidta; Chentanez,Vilai; Agthong,Sithiporn; Huanmanop,Thanasil.
Posterior antebrachial cutaneous nerve (PACN) is a branch of radial nerve supplying the skin of posterior forearm. Data regarding its anatomy remain insufficient especially the origin and number of branches. We dissected 101 upper extremities from 32 male and 20 female cadavers to expose the PACN. In all specimens, the nerve emerged from the deep fascia at the hiatus proximal to the interepicondylar line (IEL) with mean distances of 7.24 and 7.44 cm in males and females, respectively. Percentage of this distance to the arm length was 23.2 % and 26.1 % in males and females, respectively. After penetrating the deep fascia, the PACN coursed in the subcutaneous layer and crossed the IEL anterior to the lateral epicondyle (LE) in all cases. The mean distances...

Autores: Boni,R. C; Prosdócimi,F. C; Bonsi,A. B.; Almeida,T. M.; Ribeiro,L. A. M.
Anatomical brain asymmetries are subtle and still little studied in humans. Among all the animals, humans have the most asymmetric brains Crow (2004). The language faculty and handedness are localized on the left side. The objective this paper is to verify whether the temporal lobes are anatomically different. Our sample was composed of 40 post mortem adult brains of both sexes, which were investigated at the Human Anatomy Laboratory of the Nove de Julho University Center in Sao Paulo, Brazil. The brains were fixed in a solution of 5% paraformaldehyde. Three different measurements were taken using a pachimeter (Mitutoyo) and a goniometer (Card) on both hemispheres: Ml - the length of the lateral sulcus; M2 - the distance from the lateral sulcus to the...

Provedor de dados: 77
Autores: Shin,Dong Sun; Chung,Min Suk.
Medical students in the dissection room do not fully understand the ankle joint for dorsiflexion and plantar flexion as well as the subtalar joint for inversion and eversion. Thus, a three-dimensional simulation of the movements would be beneficial as a complementary pedagogic tool. The bones and five muscles (tibialis anterior, tibialis posterior, fibularis longus, fibularis brevis, and fibularis tertius) of the left ankle and foot were outlined in serially sectioned cadaver images from the Visible Korean project. The outlines were verified and revised; and were stacked to build surface models using Mimics software. Dorsiflexion and plantar flexion were simulated using the models on Maya to determine the mediolateral axis. Then, inversion and eversion...

Provedor de dados: 77
Autores: Carvajal,F; Lerma-Cabrera,J. M; Sánchez-Amate,M. C; Cubero,I.
Chlorpyrifos (CPF) is an organophosphate compound used worldwide as a pesticide in agriculture that, after subcutaneous injection, keeps acetylcholinesterase (AChE) activity inhibited within an organism for months. Ample clinical and experimental evidence shows that CPF exposure induces relevant and persistent neurobehavioral deficits in humans and animals, even after one single episode/injection. Additionally, clinical and epidemiological studies evidence that a significant percentage (60%) of Gulf War veterans as well as agricultural workers suffering from acute OP intoxication may have developed intolerance to nicotine and ethanol-containing beverages. Consistent with it, administration of a single high dose of CPF to adult Wistar rats elicited...

Valproic acid, an antiepileptic drug, is a well-known teratogenic agent; its main target organ is the neural tube, though organ malformations have also been described. The aim of the present work was to analyze the effects of valproic acid on embryo/fetal oral structures: Meckel's cartilage, muscles of the tongue, and submandibular gland. Rats received a intraperitoneal injected of Valproic acid (300mg/Kg) on the 10th day of their gestation. Females were sacrificed on day 20 post coitus, and fetuses were examined. No gross malformations were observed. The following morphological alterations were observed: lower body and placental weight; shorter umbilical cord length; submandibular gland parenchyma less differentiated with larger cellular cord and terminal...

Autores: Uribe,Francisca; Cantín,Mario; Alister,Juan Pablo; Vilos,Cristián; Fariña,Rodrigo; Olate,Sergio.
La proteína morfogenética ósea (BMP), es una proteína endógena que ha mostrado efectos significativos en la promoción de la formación ósea. El uso de BMP ha sido descrito en la reconstrucción de defectos óseos de origen traumáticos y patológicos, incluyendo la fisura alveolar, el aumento de reborde alveolar, la elevación de seno maxilar, el injerto de alveolo post-extracción, y la cirugía perimplantaria entre otros. A pesar de las ventajas asociadas al uso de BMP y que en la actualidad se aplica en combinación con matrices de colágeno, ciertas propiedades tales como su baja resistencia mecánica y su elevada tasa de liberación inicial disminuyen su eficacia en la formación ósea. En este contexto, el desarrollo de nuevos sistemas de liberación prolongada de...

Tooth size and metabolic requirements in Primates: The 'equivalence between exponents' under discussion
Provedor de dados: 77
Autores: Jiménez-Arenas,Juan Manuel.
The functional significance of teeth size, specifically postcanine tooth size has contributed a vast amount of scientific literature. Nevertheless, these studies have been based on 'equivalence between exponents'. That is, when the tooth size scales to the 0.75 power of body size exponent is interpreted as reflecting differences in metabolic requirements. On the contrary, if the obtained exponent is close to isometry, such slope is interpreted as that variation in teeth size is an incidental consequence of body size variation. In this paper, we show the results of a study in which the relationship between postcanine tooth occlusal area (PCOA) and basal metabolic rate (BMR) has been evaluated in 28 primate species. On one hand, the results obtained indicate...

Frecuencia del Hueso Interparietal o Incaico en Cráneos Atácamenos (Lican antai) Prehispánicos del Norte de Chile
Provedor de dados: 77
Autores: García-Hernández,Fernando; Murphy-Echeverría,Gabriel.
El hueso interparietal se considera un hueso intercalar originado de centros independientes de osificación y rodeado por sus propias suturas. Se encontró en fósiles homínidos y humanos tempranos. Se cree que el occipucio sufre transformaciones por mutaciones al iniciarse la evolución humana reforzando esta teoría las variaciones suturales que presenta el occipital. Sería un rasgo genéticamente dominante, propuesta ratificada por estudios experimentales. Se observa con variadas formas según la fusión de los núcleos de osificación, por lo que todos los huesos ubicados en la zona de la escama del occipital no se pueden clasificar como suturales o wormianos y deben considerarse como parte del hueso interparietal. Tratando de confirmar la alta frecuencia...

Variations of Thoracic Splanchnic Nerves and its Clinical Implications
Provedor de dados: 77
Autores: Jacob,Tony George; Wadhwa,Surbhi; Paul,Shipra; Das,Srijit.
The present study reports an anomalous branching pattern of the thoracic sympathetic chain. At the level of T3 ganglion, an anomalous branch i.e accessory sympathetic chain (ASC) descended anteromedial to the main sympathetic chain (MSC). The MSC and the ASC communicated with each other at the level of T9, T10 and T11 ganglion, indicating the absence of classical pattern of greater, lesser and least splanchnic nerves on the right side. However, on the left side, the sympathetic chain displayed normal branching pattern. We opine that the ASC may be representing a higher origin of greater splanchnic nerve at the level of T3 ganglion and the branches from MSC at T9, T10 and T11 ganglion may be the lesser and least splanchnic nerves, which further joined the...

Autores: Hohl,Leandro dos S. L; Sicuro,Fernando L; Azorit,Concepción; Carrasco,Rafael; Rocha-Barbosa,Oscar.
Morphological variation of the ramus mandibulae of wild Sus scrofa was described and correlated to sex and age differences. Young forms (n=27, 15 males, 12 females) and adults (n=23, 13 males, 10 females) were analyzed through Geometric Morphometrics (2-D) to assess differences between groups. We found significant differences between age- and sex-related shape variations at ramus mandibulae level. Young wild boars present bulky angular process with backward oriented coronoid process, while adults show slender jaw vertical ramus, and orthogonally oriented coronoid process. The ramus mandibulae in female wild boars is more robust and bulky than in males. The morphological changes between young and adult forms are related to alterations in the osteo-muscular...

Autores: Farah,Ghaus; Faruqi,N. A.
A detailed knowledge of the anatomic morphometry of infraorbital groove, canal and foramen was necessary for a surgeon while performing maxillofacial surgery and regional block anaesthesia. Modern surgical procedures as well as anaesthesia require more precise understanding of the surrounding anatomy. The aim of the study was to establish morphometrically the infraorbital foramen size and location in human foetuses, the area where this information was scanty. Sixty maxillae were dissected out from thirty human foetuses. The latter were divided into five groups on the basis of age i.e. groups I(&lt;17 weeks IUL),II (17-20 weeks IUL), III (21-25 weeks IUL),IV (26-30 weeks IUL) and V (&gt;30 weeks IUL).

Sural nerve (SN) courses from the posterior aspect of leg to the lateral side of ankle and foot. Anatomy of the SN is of clinical importance due to its involvement in nerve biopsy, nerve graft harvesting including injuries during calcaneal tendon repair. Despite substantial knowledge in the literature, more easily located landmarks and data regarding the symmetry are still needed. Ninety-eight lower extremities from 31 males and 18 females were dissected in this study. The SN originated from the union between the medial and lateral sural cutaneous nerves in 52.0 % of the legs. The distance from the union point to the intermalleolar line (IML) was 16.3±8.4 (SD) cm. The ratio of this distance to the fibular length (apex of head to lateral malleolus or LM)...

Autores: Oscar Inzunza,H; Ortega F,Waldo; Berrocal C,Claudia; Vargas D,Alex.
Si bien la tradición ha consagrado el término "tricúspide" para caracterizar a la valva atrioventricular derecha, numerosos estudios han demostrado la gran variabilidad de presentación de ésta, describiéndose casos con dos y, situaciones extremas, con seis velos valvulares. Parece existir una relación directa entre el incremento del número de válvulas y la morbimortalidad de los portadores de esta variación anatómica. En este trabajo presentamos una valva atrioventricular derecha con dos velos valvulares, estructura donde es posible identificar claramente el componente septal con una sola válvula y el componente mural que se descompone en una extensa válvula anterior y una pequeña válvula comisural anteroseptal

It has been postulated that the nasal mucosa, like other human tissues, is affected by a complex interactive network of neuropeptides, cytokines, allergic and inflammatory mediators and hormones such as estrogen, in which associations between symptoms (e.g. nasal stuffiness and coryza) and hormonal variations deriving from pregnancy, use of hormonal contraceptives and menstrual cycle phases are observed. The objective is evaluating the presence of specific estrogen receptors (types alpha and beta) in inferior turbinate mucosa in healthy subjects without nasal symptoms. Samples of nasal inferior turbinate were removed from patients undergoing aesthetic nasal surgery, and analyzed using hematoxylin-eosin staining, followed by immunohistochemical preparations...

Autores: Bin-Jaliah,Ismaeel.
Complications of chronic stress including cardiovascular disease are among the common public health problems that affect the lives of millions of people around the globe. We sought to determine whether the anti-oxidant and anti-apoptotic agent, quercetin can inhibit chronic stress-induced left ventricular dysfunction (LVD). Chronic unpredictable stress (CUS) was induced in rats using a variety of stressors in the presence and absence of quercetin (50 mg/kg body weight/day). Harvested tissues from the left ventricles (LV) of these animals were examined using basic histological staining. In addition, LV tissue homogenates were assayed for markers of oxidative and anti-oxidative stress that are known to be modulated in cardiac dysfunction. Furthermore, LV...

Autores: Muñoz,Pablo; Goulart,Douglas Rangel; Olate,Sergio; de Moraes,Márcio; Navarro,Pablo; Fariña,Rodrigo.
Facial asymmetry is relatively common, but it becomes a disease when condylar hyperplasia is involved. The purpose of this investigation was to describe and compare the morphological characteristics of hyperplastic condyles to their non-hyperplastic contralateral side. Fifteen subjects aged between 14 and 29 years with facial asymmetry and diagnosed with unilateral condylar hyperplasia were studied using cone-beam computerized tomography. Linear measurements were taken of the condylar morphology on the sagittal and coronal planes, establishing the size of the articular fossa, mandibular ramus, and other aspects. Sagittal condylar measurements showed significant differences (p=0.028) between the groups (hyperplastic side v/s non-hyperplastic side); ramus...

Autores: Catroxo,M. H. B; Nishiya,A; Sabino,E; Teixeira,P. S; Petrella,S; Milanelo,L; Vieira,J.C.F; Diaz,R. S.
Torque Teno virus (TTV) is an infectious agent of worldwide distribution isolated by the first time as the agent of an acute post-transfusion hepatitis in a patient in Japan. It has been classified into a new floating genus called Anellovirus. Recent studies showed that TTV can also be identified in serum specimens obtained from domesticated farm animals and from non-human primates. To better understand the relationship between TTV and their hosts, a study to detect virus in the serum and whole blood of Brazilian non-human primates and in the plasm of chickens was performed by applying the PCR-UTR-A technique, followed by a genomic sequence and phylogenetic analysis. By nested-PCR-UTR, the DNA of TTV was detected in sera from 4 (5.3%) of 75 Cebus apella, 2...

Autores: Vasconcellos,Henrique Ayres de; Barros de Vasconcellos,Pedro Henrique.
The Temporomandibular Joint (TMJ) has been studied for many years since the finding of mummies and fossils. In Egypt of the pharaos, papyrus from the year 3000 B.C. remark the care in which a luxation of the TMJ should be undertaken. In India, at the beggining of the Christian age, in Hipocrates' Greece and in Pergamo of Galenus the TMJ has also been the focus of several studies. But it was Vesalius (Andreae Vesalli), with his particular teaching methodology and publication of his masterpiece De Humani Corporis Fabrica, who showed the way to study Human Anatomy as it is done today. The description of the face bones, of the articular disc and the muscles used for chewing are all a contribution from Vesalius to the anatomic-functional study of TMJ

Multiple Anatomical Variations of the Hepatic Pedicle: Case Report and Clinical Application
Provedor de dados: 77
Autores: Bianchi,Homero Felipe; Algieri,Rubén Daniel; Sanjurjo,Daniela; Ottone,Nicolás Ernesto; Fuentes,Ramón.
The knowledge in detail of the anatomy of the hepatic pedicle is critical when operating it and its surroundings. The presence of anatomic variations is higher at the arterial component level than at the bile component level or venous component level, which in the 90% of the cases it appears as the classic description. The presented case in this work implies a very low frequency of appearance. For this reason, the surgeon must be alert at the moment of making a decision so as to avoid injuries that may put the patient´s life at risk.

Ordenar a lo largo del tiempo desde épocas remotas hasta el tiempo de Galeno -siglo II- las ideas imperantes sobre los nervios. Se revisaron variadas fuentes bibliográficas sobre los nervios y se ordenaron en el tiempo hasta el siglo II en relación a los conceptos sobre la constitución y funcionalidad de los nervios, comparando dichas ideas y conceptos. Históricamente se muestra que con el avance de la cultura escrita y con el lento desarrollo de nuevas ideas, tuvo que transcurrir varios miles de años para que se llegara a una mejor comprensión menos filosófica mediante la experimentación anatomo-funcional de estos elementos del sistema nervioso.

Autores: Guerrero,Marco; Ocampo,Juan; Zapata,Marcia; Yépez,Eduardo.
Cephalopelvic disproportion in the pelvic inlet is a maternal risk factor in childbirth. A high number of dystocias are attended as emergencies and end in cesarean sections because there is no way to diagnose a narrow pelvis early on, a determination which would be easy to perform and at no cost to the patient. The aim of this study was to determine the Anterior Pelvic Index (API) as a predictive estimator of the obstetric conjugate diameter to differentiate narrow and normal pelvises. The study was conducted with 200 adolescent girls aged 14 to 19 years, from Quito, Ecuador; the parents signed the informed consent and the girls agreed to take part. The interspinous distance, height and obstetric conjugate diameter were measured by ultrasonography. Then...

Plastination is a process of preservation of anatomical specimens by a delicate method of forced impregnation with curable polymers like silicone, epoxy or polyester resins with vast applications in medical fields of study. Plastination is a technique of tissue preservation developed by Dr. Gunther von Hagens in 1977. In this process, water and lipids in biological tissues are replaced by curable polymers (silicone, epoxy, polyester) which are hardened, resulting in dry, odorless and durable specimens. In this technique it is possible for us to treat every part of the body and tissues to preserve it for educational purposes. Nowadays there are new and vast varieties of applications for plastination in the educational and cultural areas. This invention has...

In this study, we evaluated the ultrastructural findings of kidney with systemic administration of different doses of atorvastatin in a rat model. Statins may have anti-inflammatory effects that would play a role in preventing the cellular damage. The aim of this study was to investigate how atorvastatin could play a role in kidney tissues. Forty adult male Wistar albino rats (200­250 g) were randomly divided into 4 groups of ten rats each (A1, A2, A3 and Control). Three different doses of atorvastatin were used to determine the effects on kidney tissues during 90 day period. The kidneys of A1 (0.1-mg group), A2 (0.5-mg group) and A3 (1-mg group) group were excised and the tissues were examined after the 90 days by transmission electron microscopy. Despite...

Study About the Development of the Temporomandibular Joint in the Human Fetuses
Provedor de dados: 77
Autores: Alves,Nilton.
The temporomandibular joint (TMJ) is a highly specialized articulation that differs from all the other synovial articulations for many reasons. In children, different from what we observe in adults, these articulations have rarely been studied under the morphofunctional aspect, mainly in the embryonary and fetal stages. In this study 10 fetuses with ages varying from 16 to 39 weeks of intrauterine life were used, and it could be observed that the fibers and thickness of the articular disc, as well as the articular capsule and the condylar process, suffer modifications according to age. It was also observed that the superior head of the lateral pterygoid muscle inserts itself in the articular disc and capsule in all the ages studied. Also, the maturation of...

Autores: Shetty,Surekha D; Nayak,Satheesha; Kumar,Naveen; Abhinitha,P.
Arterial variations of distal parts of lower limb are well documented. However, continuation of fibular artery as dorsalis pedis artery is a rare finding. Unusual course and distribution of the anterior tibial artery and fibular artery were observed during routine anatomical dissection of the right lower limb of an approximately 40-year-old male cadaver. The arteries of the crural region arose from the popliteal artery, as usual. However the anterior tibial artery was hypoplastic. The fibular artery was larger than usual and crossed the lowest portion of the interosseous membrane and continued as dorsalis pedis artery. Posterior tibial artery had a normal course and distally divided into medial and lateral plantar arteries. The awareness of these...

Autores: Hernández Caldera,Arnoldo; Muñoz Domon,Miguel; Salazar Ponce,Carolina; Leiva Villagra,Noemi.
La fisura labio palatina corresponde a una malformación congénita, caracterizada por la interrupción en la continuidad de los tejidos. La cirugía primaria del velo del paladar permite reconstituir la morfología perdida del velo palatino, sin embargo ésta no siempre considera la devolución de la anatomía del músculo de la úvula, por lo cual, el velo operado adquiere una anatomía anómala impidiendo el cierre óptimo entre cavidad oral y nasal; esta condición se conoce con el nombre de insuficiencia velo faríngea. El objetivo de este trabajo fue asociar la morfología del velo palatino con la insuficiencia velo faríngea en individuos fisurados operados. Se realizó un estudio analítico, teniendo como unidad de muestra al velo del paladar; La muestra se...

Anterior access to the L1-L5 vertebrae and disc spaces can be technically challenging, frequently requiring the use of an approach to a surgeon for an adequate exposure. The technique is used for lesion excision, corpectomy, vertebral body reconstruction with cages, realignment, and/or plating or screwing. For a successful anterior approach and a suitable instrumental design via screw, adequate morphometric knowledge about body of lumbar vertebrae and disc spaces and standardized volumetric data are also required for neurosurgeons. We aimed morphometric and volumetric evaluation of lumbar bodies and discs to contribute to a safe anterior approach during surgery. We evaluated vertebral body and disc morphometry using stereology in right-handed 25 adult...

Annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. This may cause the duodenal constriction, obstruction, peptic ulcers and other complications. We saw a classic case of annular pancreas. The head of pancreas surrounded the second part of duodenum completely. However there was no narrowing of the duodenum. The case may be of importance for gastroenterologists, surgeons and radiologists.

The aorta is the main arterial trunk in the human body, however, its variation was extremely variable. During an educational dissection, aberrant branching pattern of aortic arch was found in a Korean cadaver. The brachiocephalic trunk (innominate artery) originated from the aortic arch at the left side of the trachea. It crossed the trachea and divided into the right common carotid and subclavian arteries. The left vertebral artery originated from the aortic arch between the origins of the left common carotid artery and the left subclavian artery, then the left vertebral artery coursed upward to the transverse foramen of the C7.

Varicoceles are abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis.The pathophysiology of testicular damage in varicocele has not been completely understood. However there is an increasing body of evidence pointing towards the role of reactive oxygen species and oxidative stress in the pathogenesis of varicocele related subfertility. In the present study we examined the role of proanthocynidin-rich ethanol extract of grapefruit seed as an antioxidant in protecting the testis against damage in experimental varicocele. Three groups of rats were constructed as the first group had intact rats; experimental bilateral varicoceles were established by complete ligation of the left and right main spermatic veins in the...

El inicio y establecimiento de la gestación en los mamíferos dependen de la adaptación del sistema inmunológico de la madre para tolerar un feto semi-alogénico. La gestación en sí misma constituye un acontecimiento de equilibrio inmunológico, ya que mientras el sistema inmune mantiene la competencia para la defensa contra antígenos foráneos, mecanismos de tolerancia local y periférica previenen una respuesta inapropiada contra alo-antígenos fetales de origen paterno lo que pudiera provocar el rechazo del feto. La interacción materno-fetal es extremadamente compleja y es difícil determinar todos los componentes del sistema inmune involucrados.

Provedor de dados: 77
Autores: Quiñones,J; Bravo,S; Paz,E; Sepúlveda,N.
La melatonina es una hormona que regula los ciclos circadianos y muchos de los aspectos reproductivos de los mamíferos y es secretada por la glándula pineal en las horas de ausencia de luz. Esta hormona posee receptores de alta afinidad acoplados a proteínas de tipo G, denominados MT1. Un polimorfismo de la secuencia que codifica para estos receptores estaría involucrado en el control de la reproducción estacional de los ovinos. El propósito de este estudio busca determinar la presencia del polimorfismo del receptor MT1 en la oveja criolla Araucana, un ovino local en el que se ha registrado un corto anestro reproductivo. Para poder realizar este trabajo se utilizó la técnica denominada reacción en cadena de la polimerasa para polimorfismo en el tamaño de...

La dificultades de acceso al material cadavérico han forzado a los anatomistas a reemplazar la disección por el uso de preparaciones tratadas con diversos métodos de conservación y la utilización cada vez más frecuente de modelos anatómicos, elementos de alto costo que pretenden imitar, no siempre con éxito, a las preparaciones cadavéricas. En el último tiempo se han desarrollado métodos de impresión 3D de modelos de segmentos corporales utilizando imágenes de Tomografía Computadorizada o escáner de superficie, de modo que existe la tecnología para poder realizar réplicas de secciones corporales o de disecciones humanas para aplicarlas con fines docentes.

Knowledge of the varying drainage patterns of superficial veins of head &amp;amp; neck, in particular, jugular veins are not only important for anatomists but also for the surgeons operating at this level and to clinicians in general. The variations are important for interventional radiologists too who perform transjugular procedures, such as port implantations and the transjugular intrahepatic portosystemic shunt or selective venous samplings. Results of recent studies report that the superficial veins, especially the external jugular vein (EJV), is been increasingly utilized for cannulation to conduct diagnostic and therapeutic procedures. We report a very unusual presentation of external jugular vein on left side of an embalmed male cadáver....

La investigación tiene como principales objetivos la generación de conocimiento y la solución de problemas prácticos. Sin embargo, hay que pensar en ella como un proceso, en el que han de tomarse en consideración, y de forma rigurosa, diferentes etapas sin prescindir de ninguna de ellas. Cuando se intenta investigar sin considerar el "proceso de investigación", suelen cometerse una serie de errores, pues se aspira a hacer investigación a partir de tabulación de datos y el ulterior análisis estadístico de ellos; acto que determinará la publicación de resultados de dudosa validez, confiabilidad e interpretación. Por ende, lo primero que hay que considerar al investigar es evitar la omisión de etapas y la improvisación, pues de lo contrario se plantearán...

Provedor de dados: 77
Autores: Ilknur,Ari; Mustafa,Kafa Ilker; Sinan,Bakirci.
The pterion is a commonly used anthropologic and neurosurgical landmark defined as the junction of the sphenoid, temporal, parietal and frontal bones. It is commonly classified into four types based on sutural pattern: sphenoparietal, in which the sphenoid and parietal bones are in direct contact; frontotemporal, in which the frontal and temporal bones are in direct contact; stellate, in which all four bones come into contact at a point; and epipteric, in which a small sutural bone is found between the parietal bone and the greater wing of the sphenoid bone. In the present study, 44 Anatolian skulls from two different eras, Byzantine (13th century) and contemporary (20th century), were investigated for morphology and location of the pterion. Sphenoparietal...

Is the Conduct of Serres an Anatomical Variation in Adults?
Provedor de dados: 77
Autores: Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
In 1817, the denominated conduct of Serres was described as a formation that was highly prevalent in children's jaws, but considered as an anatomical variation in adults. In this study we analyze the presence of the denominated Serres'- conduct in 324 jaws belonging to the collection of the Universidade Federal de Sao Paulo (UNIFESP), with sex and age registration, 68 subadults of age between 0 and 2 years and 256 adults of age between 18 and 100 years. We found that the prevalence was in order to 100% in the subadults group and 42.6% in the adults group. In adults, the prevalence of this anatomical structure was greater in women than in men, with a difference statistically significant for the variable sex (Chi2 = 0.0148; I.C 95%=0.29-0.91; O.R. =0.51)....

Shape Variation and Allometry in the Precloacal Vertebral Series of the Snake Daboia russelli (Viperidae)
Provedor de dados: 77
Autores: Sarris,Ioannis; Marugán-Lobón,Jesús; Chamero,Beatriz; Buscalioni,Ángela D.
Understanding the variation of the ophidian vertebral morphology is an essential tool in snake paleobiology, but so far this field remains hardly investigated. A major problematic is the still scarce knowledge about the basis of homogeneity of intracolumnar shape variation along the vertebrae of the precloacal region in these animals. For instance, this variation can be overwhelmingly low in cases such as in vipers, for which it seems almost impossible to describe a concrete regionalization of the precloacal region without ambiguity. This study has applied geometric morphometrics to analyze if the shape variation of the vertebrae of the precloacal vertebrae of an adult specimen of Daboia russelli allows differentiating any sort of parcellation within the...

Extensor indicis brevis Muscle: an Unusual Muscular Variant
Provedor de dados: 77
Autores: Garbelotti Junior,S; Yukio Fukuda,T; Rodrigues Pereira,V; Garcia Lucareli,P; Olave,E.
Knowledge of anatomical variations of the musculoskeletal system is important for interpreting unusual clinical presentations. We observed the presence of an abnormal extensor indicis muscle in the left hand of an adult male cadaver. In this case, the muscle comes from the ligament and over the scaphoideum and trapezoideum bones and continues after the short muscle belly; it is attached to the dorsal aponeurosis of the indicis. This muscular disposition was described in other studies which demonstrated approximately 1.0% of incidence. Clinically, this anatomical variation may be associated with pain and swelling at the back of the hand. In these cases symptoms tend to increase due to mechanical stress and can be confused with the presence of a dorsal...

The Role of Anatomy Education in Facilitating Multidisciplinary Collaboration in the Treatment of Musculoskeletal Conditions ­ an Example from Australia
Provedor de dados: 77
Autores: Giuriato,Rosemary; Pather,Nalini; Ashwell,Ken; Strkalj,Goran.
Emerging changes to the healthcare system are promoting the adoption of an integrative medicine and a more patient-centred approach to healthcare. A multidisciplinary approach to the management of musculoskeletal conditions has a potential to ease the pressure off the emergency public health care system. Interprofessional collaboration in health care is paramount for this synergism to occur. It is crucial that treatment options be consistent and transparent across different health professions in order for optimum patient centred care. Using the Australian educational and health setting as an example, it is argued in this paper that anatomy education could play an important role in facilitating this consistency and transparency. The first decisive step in...

Provedor de dados: 77
Autores: Rueda-Esteban,Roberto Javier; Palacio Varona,Juliana; López-McCormick,Juan Sebastián; Hernández Restrepo,Juan David.
In response to the arising difficulty of dissection use during anatomy courses, medical schools have been forced to research alternative teaching methods. These are meant to help students develop three dimensional mental images of the human body and increase spatial reasoning, thus improving the learning process of human morphology. One of those methods, used at the Universidad de los Andes is the Diaphanization process. This technique is a well-known method for specimen preservation, used as an anatomy research and teaching tool. Even though it is frequently used, finding a standardized protocol in indexed journals is not possible, which hinders the use of the technique. The standardization of an updated protocol is a need in order to continue exploiting...

The morphological alterations that occur in the muscle fibers of denervated rat diaphragms were studied. Fifteen adult male albino rats (Rattus norvegicus) with a mean weight of 200 g and about 60 days of age were used. Chronically denervated diaphragms were obtained and the animals were sacrificed after 4, 8 and 12 weeks of denervation. The left antimere of the diaphragm was denervated by sectioning of the phrenic nerve and the right antimere served as control. Each antimere was divided into two fragments, which were used for histological (H.E.) and histoenzymological (NADH-TR and myofibrillar ATPase). After 4 weeks, denervated muscle fibers showed important light microscopic alterations: atrophy with angular profiles in cross-sections, cytoplasm...

Histological Remarks of the Uterus of Sympterygia acuta (Garman, 1877) and Sympterygia bonapartii (Müller &amp;amp; Henle, 1841) (Chondrichthyes; Rajidae)
Provedor de dados: 77
Autores: Díaz-Andrade,María Constanza; Lopez-Cazorla,Andrea; Galíndez,Elena Juana.
Chondrichthyes constitute a conserve and vulnerable clade of increasing importance. However, there is scarce knowledge about the morphological aspects of the reproduction, so that only one work exists about the structure of the gravid uterus of an oviparous species. The work presented here describes the morphological, histological and histochemical remarks of the uterus of two Rajids of the Sympterygia genus along the life cycle. Both species presented paired uteri that lead independently to a common urogenital sinus. The uteri of immature females are filiform, translucent and unspecialized tubes. When sexual development starts, all the genital system displays a transitional and progressive change. In all studied females, independently of the maturing...

Provedor de dados: 77
Autores: Mwachaka,P; Odula,P; Awori,K; Kaisha,W.
The pattern of formation of the human rectus sheath exhibits variations, it is not clear if these variations are population specific. This study aimed at describing the pattern of formation of the rectus sheath in a select Kenyan population. Formation of the rectus sheath was analyzed in eighty subjects (47 male, 33 female) during autopsies and cadaveric dissection. The anterior wall of the rectus sheath in all cases was aponeurotic and firmly attached to rectus abdominis muscle. The posterior wall of the rectus sheath was aponeurotic in 71 (88.5%) cases, the rest were musculoaponeurotic and only seen in males. In all cases the aponeurosis of internal oblique abdominis split into two lamina; a deep lamina that fused with the aponeurosis of transverses...

The Rotator Cuff Footprint: A Cadaveric Study of the Morphometry and Morphology
Provedor de dados: 77
Autores: Naidoo,N; Lazarus,L; Satyapal,K. S.
The musculotendinous hood of the rotator cuff muscle complex is formed by four tendons which thicken and merge with the underlying glenohumeral capsule as they insert onto the respective regions of the humeral head. This insertional anatomy has been reported to exhibit several pathological patterns which serve as the basis for the operative repair of cuff tears. Since previous literature concentrated on macro-evaluations of tears specific to the supraspinatus tendon, the present study aimed to investigate the macro- morphological and morphometric parameters of all four rotator cuff tendons. Observation of the insertion site configurations and computation of the relative tendon morphometry were performed once the glenohumeral region in forty adult cadaveric...

Celio-mesenteric Trunk Associated with Giant Omphalocele: Surgical Consequences
Provedor de dados: 77
Autores: Laquievre,Antoine; Hitier,Martin; Petit,Thierry; Ravasse,Philippe; Rod,Julien.
We report the first case of a newborn presenting with a celio-mesenteric trunk variation associated with a giant omphalocele. The celio-mesenteric trunk was unexpected and unseen during the staged surgical closure. After partial reintegration of the liver, the newborn presented refractory hypovolemia with anuria, leading to redo surgery. This procedure revealed ischemia of the liver and necrosis of the entire gastrointestinal tract except the colon. Despite treatment, including liver externalization, the infant did not survive. The autopsy revealed a celio-mesenteric trunk, a rare anomaly characterized by a common origin of the celiac axis and the superior mesenteric artery from the aorta. This association may explain the dramatic consequences of the...

Theatrum Anatomicum in History and Today
Provedor de dados: 77
Autores: Schumacher,Gert-Horst.
Human cadaveric dissection was introduced in Alexandria around 300 B.C. performed by Herophilos (335-255) for 30 or 40 years. Then it stopped, until Vesalius (1514-1564) began his work during the Renaissance in the Occident. He replaced the dominating theories of Galen (130-201), who had gained his knowledge from animal sections. In the 14th and 15th century human dissections were arranged in small makeshift rooms. Early designs of anatomical theatre were prepared by Alexander Benedictas from Padua 1497 and Carotas Stephanus from Paris 1564. The 1st temporary anatomical theatres arose in Italy in the 16th century, where the term Teatrum Anatomicum came from. In 1594 the 1 st permanent anatomical theatre was opened in Padua, that became the model for many...

Terminologia Anatomica también denomina al músculo fibular tercero como músculo peroneo tercero, con el código A04.7.02.039. Los tres músculos fibulares tienen su origen en la fíbula y se insertan los músculos fibulares corto y tercero en el 5° metatarsiano y el músculo fibular largo en el cuneiforme medial y base del 1er hueso metatarsiano. El músculo fibular tercero pasa detrás del retináculo de los extensores, contribuye a la dorsiflexión de la articulación talocrural y al igual que los otros músculos fibulares, a la eversión del pie. Se propone modificar la denominación del músculo fibular tercero por músculo fibular mínimo, ya que el término armoniza con los nombres de los músculos fibulares largo y corto, que aluden al tamaño y a la ubicación del...

Desde hace varias décadas se han adelantado estudios anatómicos que muestran como las poblaciones en diversos países mantienen una representación de los diferentes patrones venosos superficiales en el antebrazo. Esto contrasta con el concepto arraigado en los textos clásicos de anatomía que mantuvieron la idea de una poca variabilidad de las venas y un predominio del llamado patrón en "M". El presente estudio descriptivo, en niños que ingresaron a la Unidad de Cuidados Intensivos Pediatricos (UCIP) y requirieron acceso venoso en miembro superior, busca determinar si existe asociación entre las venas y el patrón venoso superficial del antebrazo y la necesidad de retirar los catéteres superficiales (bránula y epicutáneo).

Autores: Mwachaka,P; Hassanali,J; Odula,P.
The pterion is a point of sutural confluence seen in the norma lateralis of the skull where frontal, parietal, temporal and sphenoid bones meet. The position of the pterion exhibits population-based variations. Location of this point is important in surgical approaches to the anterior and middle cranial fossae. Specific measurements were taken on both sides of 90 (51 male, 39 female) Kenyan human skulls. The distances from the centerof pterion to the frontozygomatic suture were 38.88+3.49 mm on the right side and 38.24+3.47 mm on the left side. The pterion was 30.35+3.40 mm and 30.34+4.34 mm above the mid point of the zygomatic arch on the right and left sides, respectively.

Provedor de dados: 77
Autores: Ramsaroop,L; Hurrinarain,K; Partab,P; Satyapal,K. S.
The foramen thyroideum is described as an occasional opening existing in one or both laminae of the thyroid cartilage which may or may not contain a neurovascular component. Foramen thryoideum was first described in the literature by Segond in 1847. Some authors consider its existence a structural variation rather than an anomaly, with classical texts of anatomy providing little detail when describing this foramen. This study was undertaken to investigate the incidence and characteristics of the foramen thyroideum in the South African population. A total of 80 formalin fixed cadaveric laryngeal specimens (obtained from the Department of Clinical Anatomy, University of KwaZulu-Natal, South Africa) were dissected.

Placenta is the most accurate record of the infant prenatal experience. If the placenta is examined minutely after delivery, it provides much insight into the prenatal health of the baby and the mother. The weight of placenta is higher in diabetic pregnancy in comparison to the normal pregnancy. To study the cellular changes that might contribute to more weight of placenta in diabetic pregnancies, light microscopic and electron microscopic analysis was performed. Twenty singleton pregnancies complicated with Gestational diabetes mellitus (12 controlled on diet, 8 controlled on insulin) were selected and compared to control group. Tissue sections were processed and analyzed. The placenta of diabetic pregnancies showed no abnormality on gross observation but...

Autores: Ottone,Nicolás Ernesto; Tejedor,Mariano; Blasi,Esteban; Medan,Carlos Daniel; Fuentes,Ramón; del Sol,Mariano.
The flexor digitorum accessorius longus muscle (FDALM) is an anatomical variation that occurs with low frequency in the leg and feet. It was first described by Meckel in 1818. It arises from the tibia or fibula and extends from this towards the quadratus plantae muscle or the flexor digitorum longus muscle, crossing the medial retromalleolar canal and creating a close relationship with the elements of the tibialis posterior neurovascular bundle. A hundred and ten legs were dissected from Caucasian, adult, undefined sex cadavers, previously kept in 5% formalin solution. We developed a dissection technique in "2 times" to search for and find the flexor digitorum accessorius longus muscle, essential for the safe and successful development of surgical...

In recent years, disorders related to the development and function of the male reproductive tract has increased, thus generating a surprising decrease in semen volume and sperm count. We examined the effects of low protein and estrogen on sexual behavior and testicular maturation in male rats. We also examined FSH, LH and testosterone levels and histological damage of testis tissue. The male rats were subjected to standard long-term treatment with estradiol by oral and paranteral delivery. The number of mounts, copulatory efficiency and ejaculation latencies for the paranteral protein diet (PPD) group was significantly lower than those in a group nourished with a low protein diet (LPD) and oral protein diet (OPD) groups (P&lt;0.05).

Autores: Toomsan,Yanyong; Chomphoo,Surang; Pakkarato,Sawetree; Watanabe,Masahiko; Kondo,Hisatake; Hipkaeo,Wiphawi.
According to recent studies, it is highly possible that the occurrence of vesicular inhibitory amino acid transporter (VIAAT) is a good marker of GABA-signaling not only in the brain, but also in extra-brain tissue cells containing GABA and GAD. In view of this, the present study was attempted to localize VIAAT-immunoreactivity in the submandibular gland of mice. In the present study, the submandibular glands of male mice at various postnatal developmental stages were examined for detailed localization of VIAAT-immunoreactivity in immunohistochemistry at light microscopic level. The immunoreactivity for VIAAT was localized in epithelial cells of proximal and distal excretory ducts with the striated portion more intensely immunopositive at young postnatal...

Learning Anatomy Through Dissection: Perceptions of a Diverse Medical Student Cohort
Provedor de dados: 77
Autores: Van Wyk,J; Rennie,C.O.
The debate on how best to teach anatomy and the central role of cadaveric dissections in medical training remains topical even today. Despite the use of a variety of teaching methodologies e.g. prosected specimens, plastinated specimens, cadaveric dissection and computer-assisted learning, the amount of time dedicated to a full body human dissection programme, its clinical relevance and whether it promotes deeper learning has become a bone of contention in problem- based learning context. The implementation of student centred, PBL curricula means that students' learning is autonomous, and studies suggest the link between students' approaches to learning with their perceptions of their learning environment. Therefore, this study explored the perceptions of...

The peak age in which this anomaly is mostly found is the pediatric age especially below the age of two. Hence it is noted as an uncommon cause of intestinal obstruction and fatality in adult life. We present a case of a 26 year old man with abdominal pain and vomiting for 6 days associated fever for 3 days. Emergency laparotomy revealed ileal diverticulitis with small bowel obstruction. Ileal diverculectomy with ileal resection and ileoileal anastamosis was performed. However, the patient developed renal dysfunction leading to Multiorgan Dysfunction Syndrome and died on the fourth post...

Autores: Tothonglor,Amornrat; Agthong,Sithiporn; Huanmanop,Thanasil; Chentanez,Vilai.
Sartorial branch of saphenous nerve (medial crural cutaneous nerve) originates at the medial side of the knee and descends along the great saphenous vein (GSV) to innervate the medial aspect of the leg. Its anatomy is of concern in surgical procedures and anesthetic block. However, the measurement data related to palpable bony landmarks with comparison between sexes and sides are lacking. Dissection was done in 95 lower limbs from both sexes. We found that the nerve pierced the deep fascia alone in most cases (92.6%). This piercing point was always distal to the adductor tubercle with the distance of 5-6 cm which was 15% of the leg length (the distance between the adductor tubercle and medial malleolus). The nerve was 7 cm medial to the tibial tuberosity....

Autores: Chen Cárdenas,S. M; Mayer,N; Romanini,M. C; Rolando,A. N; Liaudat,A. C; Brun,N; Vivas,A; Gauna,H. F; Rodríguez,N.
Stress in pregnant rats alters the pattern of secretion of corticosterone (COR) and modifies transplacentally hypothalamic-pituitary-adrenal axis (HPA) fetus. Prenatal stress during the critical hypothalamic differentiation is related to decreased fertility of male offspring by an increase in the basal level of COR. This modification could induce long-term changes in the process of apoptosis in the testis. However, early postnatal handling increases maternal behavior and could reverse the effects caused by increased secretion of COR. The aim of this research was to investigate the effects of early postnatal stimulation of male rats prenatal stressed by chronic immobilization during the last two weeks of pregnancy, on the hypothalamic-pituitary-gonadal axis...

Epiblast Embryo Stem Cells Give Origin to Adult Pluripotent Cell Populations: Primordial Germ Cell, Pericytic and Haematopoyetic Stem Cells. A Review
Provedor de dados: 77
Autores: Montiel-Eulefi,E; Sánchez,R; Rojas,M; Bustos-Obregón,E.
Adult stem cells are great promise to the future of regenerative therapy, and understanding of its embryonic origin permit the discrimination of stem cell sources. Embryonic stem cells derived from inner cell mass of blastocyst originate the primordial germ cells, and pericyte stem cell associated to vessels endothelium in yolk sac. Currently, it is being proposed that embryonic primordial germ cell could originate hematopoietic stem cells based on the detection of germ cell markers (SSEA-1/TEC-1, Oct-4 and Nanog) in stem cell harvested from fetal liver and bone marrow. However, different experimental evidence points at two separate differentiation routes toward primordial germ cells, and hematopoietic stem cell with the same embryonic origin. The...

Establish a person's identity can be a very complex process, one of the main objectives of the forensic sciences. The analysis of the teeth, fingerprints and DNA comparison, are probably the most used technics, allowing fast and secure identification processes. However, these techniques can not always be applied, in some cases, it is necessary to apply different and less known techniques. In this work, a systematic analysis of the shape and dimensions of the palatal rugae was performed. We analyzed 120 subjects of both sexes, between 15 to 20 years olds, fully dentated, and by calcorrugoscopy were determined the shape, size, number and position of the palatal rugae. The most prevalent palatal rugae shape was sinuous (43%) followed by curve (27%), line...

Provedor de dados: 77
Autores: Jerbi,Hassen; Pérez,William.
The barbary stag is an intermediate feeder ruminant of the Cervidae family. The macroscopic anatomy of the stomach in one adult barbary stag was described. The stomach of the barbary stag was composed of the four classic compartments of the ruminants. The weight of the full stomach was 10.5 Kg. The ruminal papillae were distributed unevenly in the rumen. The maximum height of the cristae reticuli was 0.2 cm. The cellulae reticuli were mostly undivided. The curvatura omasi measured 15.0 cm and the omasum had 15 primary, 10 secondary, 10 tertiary and 17 cuaternaryLaminae omasi. The abomasum had about 12 plicae spirales abomasi.We concluded that the stomach morphology of the barbary stag had characteristics of other intermediate feeder ruminants.

El nervio isquiático, ramo del plexo sacro, abandona la pelvis pasando, generalmente, por debajo del músculo piriforme. Este nervio puede presentar variaciones en su relación con el músculo piriforme, entre ellas, las referidas a la división alta. Sin embargo, son pocos los trabajos que correlacionan esta división con variaciones anatómicas y su relación con el músculo piriforme, en fetos humanos. Con el propósito de verificar una posible asociación entre el trayecto y relaciones de ramos del nervio isquiático, fueron disecadas 100 regiones glúteas de fetos humanos. Se encontraron 3 tipos de variaciones entre el nervio isquiático y el músculo piriforme: en 8 casos (16,0 %) el nervio fibular común pasó a través del músculo y el nervio tibial transcurrió por...

Provedor de dados: 77
Autores: Jalili,C; Khani,F; Salahshoor,M. R; Roshankhah,S.
Nicotine consumption can decrease fertility drive in males through inducing oxidative stress and DNA damage. The color of turmeric is because of a substance called curcumin for which some anti-oxidative and anti-inflammatory properties have been identified. In this study, various doses of curcumin (10, 30 and 60 mg/kg) and curcumin plus nicotine (10, 30 and 60 mg/kg) were administered intraperitoneally to male mice for 28 consequent days and reproductive parameters were determined. The results indicated that nicotine administration (0.5 mg/kg) significantly decreased testosterone level, count and motility of sperms, and testis weight compared to control group. However, increasing the dose of curcumin significantly increased reproductive indices in most of...

Forensic Dentistry as a Morphological Exercise in the Medico-legal Investigation of Death
Provedor de dados: 77
Autores: Fonseca,Gabriel M; Cantín,Mario; Lucena,Joaquín.
In forensics, the nature of collected evidence makes analysis in many disciplines complex. Each type of trace evidence requires a unique systematic approach, and even though these approaches are significantly based on the size and morphology of the evidence being examined. In 1999, the Council of Europe Committee of Ministers adopted the Recommendation No. R (99)3 on the harmonization of medico-legal autopsies. This document promoted the adoption of internationally recognized and standardized protocols for forensic autopsies. Nevertheless, the interdisciplinary philosophy still needs integration of information from various investigative sources. An orientated and correct examination of the oral cavity requires specific knowledge of its anatomy and...

Autores: Taheri,Mohammad Mehdi Hassanzadeh; Afshar,Mohammad.
Variations of the terminal branches of the brachial plexus in the upper limb are abundant and frequently have been reported. But connection between its radial and ulnar nerves at humeral level is very rare. During routine dissection of the right arm of a 75-year-old male cadaver in the Department of Anatomy of Birjand University of Medical Sciences (BUMS), in Iran, we observed a connection between radial and ulnar nerves, and from the literature reviewed, we found only two cases that had been reported previously, one of them was unilateral and the other bilateral. Awareness of such variations are very important for surgeons and diminish the possible complication of regional anesthesia and surgical procedures, hence, we decided to report it.

Some dental treatments that are performed in the mandibular teeth involve manipulation of anatomical structures near the dental periapex, so it is likely to cause nerve damage due to the proximity of the inferior alveolar nerve with the apices of the mandibular teeth, mainly in the molar area. The aim of this study was to determine through Computed Tomography (CT) scan the existing distance between the mandibular canal and the anatomical structures adjacent to its path which will help to reduce the risk of injury to the inferior alveolar nerve during the different dental treatments developed in this zone. A cross-sectional study was performed where the study population consisted of 50 patients of both sexes, between 20 and 30 years with a full dentition...

When a vein segment is grafted into arterial circulation, biomechanical forces stimulate modification of its structure. This morphological adaptive response is progressive during a medium or long term and occludes the vessel lumen, leading to a graft failure. The objective of this study was to characterize the early morphological response of the vascular wall in a terminal-terminal vascular vein graft model in Wistar rats. A segment of the femoral vein was placed in the femoral circulation. An end to end microsurgical graft anastomosis technique was implemented and standardized in twenty rats. The samples were processed with histological technique to analyze the overall structure with hematoxylin and eosin, the composition of the vessel wall with Masson...

Autores: Espinoza-Navarro,Omar; Ponce-LaRosa,Carlos; Bustos-Obregón,Eduardo.
The environment is negatively affected by the increasing accumulation of both natural and man-made waste and by-products. Organophosphorous pesticides -malathion, diazinon and methamidophos- are used worldwide in pest control. The aim of this report is to review the effects of organophosphates on the male reproductive tract of mice, rats and earthworms, and to evaluate their projection into the human population. Assessing failures in the male reproductive system is an excellent in vivo biomarker to determine the level of toxicity of suspected pollutants. In rodents organophosphates cause decreased testicular weight and sperm density, abnormal tubular plugging and increased teratozoospermia. In earthworms they cause a significant decrease in body weight and...

Autores: Pathak,Archana; Katiyar,R. S; Sharma,D. N; Farooqui,M. M.
The study revealed that the testes of one-day-old Gaddi goats have descended in the scrotum along with adnexa. They were elongated compressed latero-medially and became ovoid during their postnatal growth and morphogenesis. The two testes were not different significantly in their weight and measurement. The average weight which was about 2.9 gm at birth grew to 107 gm (40X) in pubertal animals and nearly maintained it during the post-puberty (113 g). The mean length (1.46 cm), width (0.85 cm) and thickness (0.62 cm) also grew by 47, 60, and 83 times, respectively. In post-pubertal animals it measured 7.06 x 5.20 x 5.10 cm. The study indicated a very fast growth of the testes from birth to puberty, which did not alter significantly after that. A relatively...

A mandibular fossa depth correlation with dental condition and age in humans. 120 fresh male mandibular fossas were measured from the deepest area of the fossa to a horizontal reference line. The samples were classified according to age and dental state (dentate, partially dentate and totally edentulous) and a multivariate analysis was employed. Subjects average age was 41.1 (20-85). There were more partially dentate individuals (59.16%) than dentate (30%) or edentulous ones (10.83%). Average fossa depth was 6.9 mm (6.6-7.1 mm 95%CI) which significantly decreased with increased age and dental health deterioration (p&lt;0.01). A period of five years edentulism increased the likelihood of mandibular fossa flattening (&lt;6.9 mm) by 20.6% and 7.2% in dentate...

Aspectos Moleculares en la Formación de la Cara y del Paladar
Provedor de dados: 77
Autores: Montenegro,María Angélica; Rojas,Mariana.
En mamíferos, la adhesión y fusión de los procesos faciales y palatinos, son mecanismos esenciales en el desarrollo del paladar primario y secundario. La falla de cualquiera de estos procesos trae como consecuencia la formación de labio leporino o fisura palatina. En ambos casos, los procesos opuestos adhieren a través de desmosomas para formar una lámina epitelial media la cual desaparece por transformación epitelio-mesenquimática. La apoptosis ocurre sólo en las células del periderma. En el paladar secundario, estos procesos están regulados por TGFß-3, pero este factor no está presente en los procesos maxilares o nasales que forman el paladar primario, por lo cual en la formación del labio actuarían otros factores tales como Shh (sonic hedgehog) y BMP...

Autores: Ilayperuma,Isurani; Nanayakkara,Ganananda; Palahepitiya,Nadeeka.
Prediction of stature from incomplete and decomposing skeletal remains is vital in establishing the identity of an unknown individual. It has been stated that a variety of factors such as race, gender and nutrition play an important role in determining the height of an individual. Estimation of stature from measurements of various long bones has been achieved with varying degree of accuracy. Those studies resulted in establishing different formulae for the estimation of stature for the respective populations. However, evidence shows that there is a great void in such norms for Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression models between the ulna length and height of an...

Provedor de dados: 77
Autores: Carvallo,Eugenia; del Sol,Mariano.
La relación anatómica de la vena safena magna (VSM) y del nervio safeno (NS) en la región talocrural tiene importancia anatomoclínica, sin embargo existen pocos trabajos en la literatura anatómica. Se disecaron 30 pies de cadáveres formolizados de individuos adultos de ambos sexos, describiéndose el origen de la VSM y su relación con el NS en la región talocrural; se midió la distancia entre el NS y la VSM a nivel del ápice, margen anterior y a 1 cm del margen superior del maléolo medial. La VSM se originaba de la unión de la vena marginal medial del pie y el plexo venoso dorsal. La relación anatómica entre la VSM y el NS es variada, cursando el NS en un 63,3 % anterior y 30% posterior a la VSM y en 6,7 % el NS se dividía en dos ramos los cuales...

Autores: Spinardi,Julia Regazzini; Goncalves,Isis  Rocha Dias; La Falce,Thiago Souza; Fregnani,José Humberto Tavares Guerreiro; Barros,Mirna Duarte; Macea,José Rafael.
Benign inclusions are foci of non-neoplastic ectopic tissue in lymph nodes. They are classified into three types: epithelial, nevomelanocytic and decidual. It is important to identify them for the differential diagnosis with lymph node metastases, particularly among patients who present proliferative benign lesions. In general, epithelial inclusions are presented inside lymph nodes as epithelial cysts or as numerous structures resembling ducts. The cells of these structures may originate from the cells of paramesonephricus ducts, salivary glands, breast tissue, thyroid follicles, squamous epithelium or mesothelium. Paramesonephricus -type inclusions are almost exclusively found in pelvic lymph nodes and, in appearance, they resemble the epithelium of the...

Autores: Ibe,C. S; Onyeanusi,B. I; Hambolu,J. O; Ayo,J. O.
The architecture of cranial and non-cranial nerve nuclei in the medulla oblongata of the African giant pouched rat was studied by means of light microscopy. Serial sections of the medulla oblongata, in coronal and saggital planes, were stained with the cresyl fast violet and silver stains, respectively. Sections in the saggital plane were used as a guide, while coronal sections were used to identify the nuclei in the rostrocaudal extent of the medulla oblongata. With the obex serving as the landmark, nuclei rostral and caudal to the obex were delineated. Cranial nerve nuclei whose architecture were defined were the motor nucleus of hypoglossal nerve, motor nucleus of vagus nerve, cochlear nucleus, vestibular nucleus and nucleus ambiguus, while non-cranial...

Morphological Studies on the Vagina and Vestibule of Dromedary Camels (Camelus dromedarius)
Provedor de dados: 77
Autores: Sayed-Ahmed,Ahmed; Elshafey,Anwer; Abd-Elmaksoud,Ahmed.
The camel (Camelus dromedarius) is an important multipurpose livestock species and its meat represents about 10% of the red meat consumption in Egypt. The reproductive efficiency of camel under natural condition is generally considered to be low. Sound knowledge about the tubular genital organs of this species might facilitate the application of new reproductive methodology. Our study was therefore conducted to investigate the morphology of mucosal surface of vagina and vestibule on camels using light, scanning and transmission electron microscopy. The mucosal surface of vagina consisted of stratified columnar epithelium with mucous secreting cells (goblet-like cells). SEM of vagina revealed the presence of longitudinal primary and secondary folds and...

Ratas malnutridas prenatalmente con una dieta isocalórica y baja en proteínas, presentaron un menor diámetro axonal promedio en el esplenio callosal que los animales control, tanto de las fibras mielínicas como amielínicas. También se observó una mayor densidad axonal promedio, con respecto a los controles. Estas observaciones sugieren que: 1) las conexiones cortico-corticales (interhemisféricas) son vulnerables a la malnutrición proteica; y 2) lo anterior tendría incidencia en la velocidad de conducción interhemisférica, en particular con lo que dice relación con las conexiones visuales

Octopus mimus (MOLLUSCA: CEPHALOPODA) EMBRYO MISDEVELOPMENT DUE TO CHRONIC EXPOSURE TO THE ORGANOSPHOSPHORUS PESTICICE PARATHON
Provedor de dados: 77
Autores: Gutiérrez-Pajares,Jorge L.; Olivares,Alberto; Bustos-Obregón,Eduardo.
Pesticides are of ample worldwide use. At present there is a growing concern about seawater contamination by these chemicals. Developing aquatic organisms are particularly at risk. For this reason, early development of Octopus mimus embryos under exposure to commercial Parathion was examined. Concentrations over 0.4 mM of the pesticide altered formation of the embryonic disc at the blastula stage, resulting in abnormal gastrulation and arrest of further development. This toxic effect may be due to the blockade of DNA synthesis elicited by organophosphoric pesticides causing diminished number of blastodermic cells at the time of epiboly, thus hindering the start of invagination. Seawater contamination seems, therefore, of relevance for survival of exposed...

Facial palsy, parotid diseases and others are a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. Parotid gland diseases also are very common occurrence. In this particular case, the knowledge of surgical anatomy of the facial nerve and its correlations with the parotid gland is very important for an adequate preservation in the cases of surgery of benign and malignant diseases of the parotid gland. Although the surgical anatomy of the facial nerve has been well documented, the concept of surgical treatment for parotid tumors, facial palsy (neurorraphy techniques) and submandibular surgical approach are rarely challenged now.

The Topography and Gross Anatomy of the Abdominal Gastrointestinal Tract of the Persian Squirrel (Sciurus anomalus)
Provedor de dados: 77
Autores: Sadeghinezhad,J; Tootian,Z; Akbari,G. H; Chiocchetti,R.
The Persian Squirrel (Sciurus anomalus) is the only member of the Sciuridae family found in the Middle East. It is herbivorous, feeding mostly on pine acorns and other seeds and fruits. It is a wild animal nesting in forest trees, although it is frequently found close to city gardens and parks. As Persian squirrels are also found in homes as "companion animals", veterinarian assistance may be sometimes required; this is a good reason to gain more specific knowledge of the anatomical features of this animal. Due to the scantiness of relevant literature, we carried out this study with the aim to provide further information on the topography and gross anatomy of its abdominal gastrointestinal tract (GIT). Seven animals of this species were utilized to measure...

The phylogenetic proximity of primates to humans, along with their behavioral, biochemical, and anatomical similarities, make such animals more interesting experimental models for biomedical researches, as compared to classical laboratory animals. Another aspect that has called the attention of researchers is the differentiated quadrupedalism present in some primates. The tufted capuchin monkey uses the ground and tree branches as its support for locomotion, showing various postures while performing this task. On the basis of this information, we have decided to study the rectus abdominis muscle of the tufted capuchin monkey, with the following goals: the frequency and area of fiber types; its possible compartmentalization; and identify if this muscle is...

Forelimb Myology of the Golden Pheasant (Chrysolophus pictus)
Provedor de dados: 77
Autores: Zhang,Zihui; Yang,Yan.
Morphological work on the appendicular myology of birds forms the basis for comparative, functional and systematic studies, but our knowledge of the descriptive anatomy of birds is still very incomplete. The musculature of the wing muscles of the Golden Pheasant (Chrysolophus pictus), an endemic species of China, is studied in detail. All wing muscles are present as in other Galliformes. Myological characteristics including the absence of a deep layer of M. pectoralis pars thoracicus, well development of anterbrachial muscles, as well as the occurrence of a distinct fleshy slip from the proximal belly of M. biceps brachii, are suggested to be associated with its flapping flight. This paper is the prelude to functional analysis on muscle architecture in...

Thoracic Vagal Ganglion and Referred Craniofacial Pain: a Case Report and Review
Provedor de dados: 77
Autores: Ramírez Aristeguieta,Luis Miguel; Ballesteros,Luis Ernesto; Forero,Pedro Luis; Conde,Carlos.
The presence of a ganglion-like tumefaction is reported in the mediastinal course of the right vagus nerve at Tl level in a cadaver in the Universidad Industrial de Santander's morphology laboratory. The vagal ganglion was located next to hyperplasic lymphoid nodes in para-tracheal and tracheal-bronchial levels, agglomerating in a large lymphoid mass in the carina and the pulmonary hilum. Anatomical-pathological study revealed a marked, diffusely distributed, predominantly histo-lymphocyte mixed inflammation, separating the epineurium, producing lysis of the vagus nerve fibers. This finding showed the degeneration of this cranial par by mediastinal pathology. This provided a possible explanation for the physiopathology of pain referring to the head and...

Autores: Ortíz-Ordoñez,Esperanza; Mendoza-Santana,Elizabeth L; Belmar-Pérez,Jorge; Padilla-Benavides,Teresita del Niño Jesús.
Some of the gastropods of the Baja California peninsula are of commercial value, but the majority are not. Among the less commercially valuable species are members of the genus Tegula, which are ecologically important because of their abundance and the trophic level they occupy. Mature specimens of T. eiseni, T. funebralis, T. aureotincta, T. gallina, and T. regina were collected from two rocky reefs close to Bahía Tortugas, B.C.S. and were processed using a paraffin-embedding technique. All of these species are dioecious, without external sexual dimorphism; in adults, the female gonads are green moss colored while male gonads are cream colored. The gonadal tissue is limited externally by a single ciliated cylindrical epithelium with plentiful granular...

Insertion of the Superior Head of the Lateral Pterigoid Muscle in the Human Fetuses
Provedor de dados: 77
Autores: Altruda Filho,Luiz; Alves,Nilton.
The lateral pterygoid muscle, more specifically its superior head, as we know, is closely related to the temporomandibular joint (TMJ). Particularly in children, in contrast with what was observed in adults, these joints have been rarely studied, by the anatomic functional aspect, little knowing about its functions in the embryonic and fetal periods. We used, in this work, 12 fetuses ranging in age from 16 to 39 weeks of intrauterine life, where we observed that the superior head of the lateral pterygoid muscle is inserted in the disc and in the articular capsule, in all age groups studied, and also, that the fibers and the thickness of the articular disc is, as well as the articular capsule suffer modifications in accordance with the period of development

Provedor de dados: 77
Autores: Xie,Zhao Hui; Zhong,Hong Bo; Li,Hai Jun; Hou,Yu Jie.
The morphology of Chinese fire-bellied newt liver consists of 5 lobes, with exception of a few individual differences present, which are composed by a number of hepatic lobules. Passing through the center of the lobules, a central vein radiates and is arranged in orderly row from one to several layers. The interval of the hepatic cords or masses are irregular and variable sinusoid. The hepatic sinusoidal wall consists of one layer endothelial cells or Macrophagocytus stellatus (Kupffer cells), which have protrusions and elongations. The intervals of the hepatic cells have perisinusoidal space (space of Disse). The hepatic cell is polygonal in shape with uniform, round or oval nucleus, 17.8­12.4µm in diameter, mean 14.2 µm 2-6 nucleoli, nuclear-cytoplasmic...

Provedor de dados: 77
Autores: Yang,Shengbo; Hu,Shuangjiang; Tian,Xufeng; Hu,Shuaiyu.
The nerve entry points (NEPs) cannot be accurately localized for the treatment of muscle spasticity in neurolysis. The aim of this study was to develop a new method of accurately localizing nerve entry points in relation to bony landmarks. NEPs in human cadavers were coated with barium sulfate. Method 1 consisted of horizontal and longitudinal reference lines being designated based on bony landmarks, followed by radiography and measurements using picture archiving and communication system software. Method 2 involved sewing the barium sulfate-soaked suture thread into the skin to designate the horizontal and longitudinal reference lines, followed by computed tomography (CT) scanning to determine the skin surface location and puncture depth for the NEPs....

Autores: Staka,Gloria; Disha,Metush; Dragidella,Fatmir.
Cephalic and facial indices are used to estimate the racial and sex differences. This study was carried out to establish standards for craniofacial variables and distribution of cephalic and facial indices in Kosovo - Albanian population. The study population consisted of 204 dental students (101 males and 103 females, aged 18 to 30). Four basic craniofacial variables (head length, head breadth, morphological face height and face breadth) were measured to obtained cephalic and facial indices. All measured craniofacial variables are considerably higher in males than in females (p&lt;0.0001). In the Kosovo ­ Albanian population brachycephalic type of head (44.61 %) and hyperleptoprosopic type of face (63.34%) prevail.

Andreas Vesalius (1514-1564): Fundador de la Anatomía Humana Moderna
Provedor de dados: 77
Autores: Romero Reveron,Rafael.
Andreas Vesalius, (Andries van Wesel), nació en Bruselas, Flandes, actual Bélgica, el 31 de diciembre de 1514. Estudió Medicina en las Universidades de Lovaina, Paris y Papua, donde se doctoró, graduándose magna cum laude, el 5 de diciembre de 1537, a los 23 años de edad; al día siguiente fue nombrado explicator chirugiae, el equivalente a una cátedra de Cirugía y Anatomía, en la misma Universidad. Durante sus demostraciones prácticas él mismo hacía sus disecciones anatómicas, en lugar de confiárselas a un cirujano, rompiendo con la tradición. Vesalio estudió y develó la Anatomía Humana más que todos sus predecesores al crear, en 1543, De humani corporisfabrica (Sobre la estructura del cuerpo humano), el cual puede considerarse como el primer tratado...

The Histological Analysis of the Glenohumeral "Critical Zone"
Provedor de dados: 77
Autores: Naidoo,N; Lazarus,L; Satyapal,K. S.
The arterial integrity of the "critical zone" of the rotator cuff has led to much uncertainty regarding rotator cuff tendinopathy. As the region of the supraspinatus tendon is the most common area affected by impingement, its central aspect is situated approximately 10 mm from the insertion at the greater humeral tubercle. Although many studies have investigated the vascularity of the "critical zone", there still appears to be lack of consensus regarding its extent. Through the employment of gross dissection and standard histology analysis of twenty-five adult bilateral cadaveric scapulo-humeral regions (n = 50), this study aimed to quantify the degree of vascularity, or lack thereof, within the "critical zone" by evaluating its relative morphometric...

Commentary: Is the Evidence for Localization of Nephrin on the Slit Diaphragm Rigid?
Provedor de dados: 77
Autores: Hipkaeo,Wiphawi; Suzuki,Ryoji; Abe,Hiroshi; Chaisiwamongkol,Kowit; Kondo,Hisatake.
After careful observation of immuno-electron microscopic findings of the renal glomerular podocyte slit so far published by various authors, it should be noted that no convincing evidence is present for localization of nephrin-immunoreactivity in the slit itself, but that nephrin-immunoreactivity is dominantly localized along the membranes of podocyte pedicles from their tip over a substantial extension. In addition, the notion that the slit diaphragm is composed of strands is compatible with the widely distributed view that the slit strands represent rod-shaped nephrin molecules. However, 3-D findings that the diaphragm is composed of not only strands but also membranous elements have recently demonstrated separately by embedment-free section electron...

Autores: Ntombela,N. S; Lazarus,L; Satyapal,K. S.
This report describes two cases of multiple anomalies associated with the azygos venous system. In Case 1, the hemiazygos vein drained the 9th to 11th left posterior intercostal veins. At T9 vertebral level, the interazygos vein passed obliquely and anterior to the aorta to drain into the azygos vein on the right. In Case 2, the common venous trunk formed by the accessory hemiazygos and hemiazygos veins passed anterior to the aorta to drain into the azygos vein at T9 vertebral level. These findings represent pre-aortic inter-azygos veins, which is a rare variation of the azygos venous system. Pre-aortic inter-azygos veins can mimic pathologies such as enlarged lymph nodes, tumors and aneurysms leading to misinterpretation of radiographs, computerized...

A comparative study of skull types was done using 65 skulls obtained from three different goat breeds in Nigeria namely; Red Sokoto, Sahel and West African Dwarf. A unique depression was consistently found at the cornual end of the temporal line of the skull medial to the middle portion of the caudal boundary of the orbit and dorsal to the lateral portion of the parietofrontal suture. The depression was found in all the breeds studied, and in both sexes on the lateral sides of both cornual processes of the frontal bones. The features (depth, height and width) of the depression were found to vary without regard to either sex or breed. A search of the literature did not yield any information on this depression in the skull of the goat. Consequently, we...

Autores: Sethi,Ashwani; Singh,Ishwar; Agarwal,A. K; Sareen,Deepika.
The exact mechanism of the pneumatization of the mastoid air cell system and the factors influencing the pneumatization are poorly understood. Both genetic as well as acquired factors have been implicated to influence this pneumatization process. Since pneumatization of the mastoid air cell system is considered an important prognostic factor in the outcome of reconstructive ear surgeries, a cohort study was carried out to assess the role of two important acquired factors i.e. duration of chronic otitis media and auditory tube functional status on the pneumatization of mastoid air cells. 50 individuals with unilateral chronic otitis media underwent assessment of their mastoid air cell system using planimetry and auditory tube functions using flourescein dye...

Actualmente existen pocos estudios sobre la anatomía y fisiología del tracto digestivo del conejo (Orycotolagus cuniculus), estos estudios están encaminados a la nutrición y biología del conejo, pero pocos abordan la anatomía con la visión de un cirujano. Por otro lado existen algunos estudios que proponen al conejo como modelo animal para cirugías laparoscópicas del esófago distal y el estómago. En la mayoría de los casos se utiliza como modelo sin tener en cuenta las características anatómicas específicas de esta especie, por lo que es fundamental realizar un estudio anatómico de la zona del esófago abdominal, cardias y estómago del conejo, que exprese las características y diferencias anatómicas para que los cirujanos estén más familiarizados antes de...

Identifying the maturity stage of specimens is essential for the determination of the spawning season, which in turn facilitates the formulation of adequate fisheries management measures for the sustainable use of sea resources, such as abalone. This study aims to validate, based on histological evidence, a gonad maturation scale that encompasses four morphochromatically-defined stages (developing, maturity, spawning and resting) for females and males, plus an additional stage for reproductively inactive (undifferentiated) specimens, to be used as an identification key. Given the similarity between Haliotis fulgens and Haliotis corrugata as to their morphochromatic features, the gonadal maturation scale can be used for both species.

Preoperative Computed Tomographic Evaluation of Inferior Nasal Concha Hypertrophy and its Role in Deciding Surgical Treatment Modality in Patients with Deviated Nasal Septum
Provedor de dados: 77
Autores: Mrig,Sumit; Agarwal,A. K; Passey,J. C.
Deviated nasal septum is associated with compensatory hypertrophy of the inferior nasal concha on the contralateral side. In the past conventional septoplasty was done for the deviated septum, which would improve the patency on the side of deviation but would worsen it on the opposite side due to reallocation of the septum to the midline. The present study of 50 patients unfolds the anatomical composition of the inferior nasal concha based on the computed tomographic scan and help the otolaryngologist to determine whether to add turbinoplasty to standard septoplasty procedure or not.

This study investigated the effects of visfatin on the structure and the immunity levels in the small intestine of LPS-induced rats. Forty Wistar male and female SPF rats were randomly and equally divided into four groups: the saline (control), vistfatin, lipopolysaccharide (LPS), and visfatin+LPS co-stimulated. The functions of visfatin in the intestinal mucosal immunity were investigated by examining the variation of tissue structure, inflammation and immunity-related proteins in the intestine of immunologically stressed rats using HE staining, ELISA, immunohistochemistry and Western Blot. The results showed that, when compared with the control group, the visfatin-treated group showed a decrease in the intestinal villus height and width, and a...

Morphological Variation in the Seahorse Vertebral System
Provedor de dados: 77
Autores: Bruner,Emilano; Bartolino,Valerio.
The vertebral system in Hippocampus hippocampus is highly specialised because of the vertical locomotion and tail prehensility. The vertebral elements represent a special case of morphological changes, being the metameric structures organised along a natural functional series. We investigated the shape changes along the vertebral spine in H. hippocampus through geometric morphometrics, in order to describe functional and structural patterns. Actually, the dorso-ventral tail bending ability in the genus Hippocampus is one of the most impressive morphological modifications in the evolutionary history of fishes. Vertebrae were analysed using a 2D configuration from the left lateral view. The variation along the vertebral series suggests the identification of...

Autores: Sripanidkulchai,Kittisak; Chaisiwamongkol,Kowit; Iamsaard,Sitthichai.
In submental and around the mouth areas, the superfacial muscles are considered in surgery of some deformities of mouth angle. Herein, we report a rare case of the Transversus menti muscle (TM) in a Thai 74 year-old male cadaver. This TM originated from both sides of the oblique line of depressor anguli oris and formed as transverse fibers in submental area. Their fiber ran under the chin and was superficial to platysma muscle. The TM was innervated and supplied by mandibular branches of facial nerve and small branches of the submental artery. This report attempted to discuss the possible function and clinical significance of the TM.

Unusual Relation of the Median Nerve with the Accessory Head of the Biceps Brachii Muscle: An Original Case Report
Provedor de dados: 77
Autores: Mas,Nuket; Pelin,Can; Zagyapan,Ragiba; Bahar,Hakan.
During the laboratory dissection of the brachial region and the arm, an abnormal relation of median nerve with the accessory head of biceps brachii muscle has been observed unilaterally on the right upper limb of a male cadaver. Whereas the short and long heads have their normal origin, additional-excess third head originated from the anteromedial surface of the superior part of the humerus. Some fibers of this accessory head on the medial side arise from the deep fascia surrounding the brachialis muscle. The fibers then cross the median nerve superficially before joining the third head which has inserted into a common tendon together with the long and short heads. To have information of such variations is of importance either for anatomists or clinicians...

Desarrollo del Aparato Digestivo
Provedor de dados: 77
Autores: Roa,Ignacio; Meruane,Manuel.
El aparato digestivo deriva del endodermo y el mesodermo, que forman su epitelio y la musculatura lisa respectivamente. Al igual que en el resto de los sistemas, existe un interacción epitelio-mesenquimática mediada por moléculas como Hedgehog, BMP y FoxF1 que determinan el crecimiento intestinal en sus ejes principales. Los genes Hox, junto con el resto de las moléculas, participan en la regionalización del sistema digestivo. En sus inicios lo denominaremos intestino primitivo, formado por un tubo endodérmico que deriva del saco vitelino; dividiéndose en intestino anterior, medio y posterior. En esta revisión veremos cómo estos 3 segmentos darán origen a las diferentes estructuras del sistema digestivo en los vertebrados.

Son los dientes con mayor prevalencia de agenesia junto a los segundos premolares e incisivos laterales (Fuller &amp;amp; Denehy, 1984). La prevalencia varía entre 9 y 37% (McNamara &amp;amp; Foley, 2006), en tanto, Arboleda et al. (2006) señalan una prevalencia del 20%. La literatura señala variables estadísticas porcentuales, por género, por arcada dentaria, por lado y por diente, con escasos artículos sobre grupos originarios de Chile. La población en estudio consistió en 33 hombres y 57 mujeres de 16 a 55 años, de...

Autores: Alves,Nilton; Cândido,Paulo Laino; Frazão,Renata.
The pronator quadratus is the principal muscle responsible for pronation of forearm, helped by the pronator teres. To study the innervation of the pronator teres, eighteen forearms from a formol fixed corpses were dissected and the relationship of the median nerve to the pronator teres was examined. The elbow articular line was used as reference point. In all cases the most branches of the median nerve to the pronator teres began in the arm distal third part, whereas the most branches penetrated at the distal half of the forearm proximal third part (75% in right upper limb and 75.8% in left upper limb). The treatment of pronator syndrome could be making easier with the knowledge of the anatomical distribution of nerves

Provedor de dados: 77
Autores: Das,Srijit; Paul,Shipra.
During routine dissection, an unusual formation of median nerve was detected in the right upper limb of a 55 year old male cadaver. The median nerve had an additional contribution from lateral cord. The two branches of the lateral cord designated as upper and the lower branches were observed at different levels. The upper branch was in close contact with the third part of the axillary artery and it crossed the vessel anteriorly to unite with a branch of the medial cord to form the median nerve. The median nerve thus formed was related medially to the axillary artery (instead of the normal position of being anterolateral). The median nerve descended below and was joined by an additional lower branch from the lateral cord. Interestingly, the ulnar nerve...

For several generations physical anthropologists measured skulls in the belief that thereby they were likely to obtain results, this would enable them to trace the relationships between the races of mankind. It was believed that the form of the skull in particular remained constant in each race, and that different races typically showed different facial indices. Form of the head and face is now known to be subject to change through environmental influences. Measurement is necessary in order to obtain this kind of knowledge, and in order to be able to give as accurate a description of an individual or group of individuals as possible. The present study aimed at measuring facial index of both sex in Malaysian and Indian students. 300 students of both nations...

In this study, we evaluated the ultrastructural findings of testis with systemic administration of different doses of melatonin during ischemic period in a rat model of testicular torsion/detorsion (T/D). Testis ischemia-reperfusion (I/R) injury was induced by torsion of the left testis, with a 720 degrees twisting of the spermatic cord so as to produce a total occlusion of testis for 2.5 hours. Subsequently, the same testis was then detorsioned. According to surgical procedure in each group, unilateral orchiectomies were performed for histopathologic examination. The groups were labelled as control group, torsion group (T), torsion and detorsion group (T/D), torsion-detorsion and melatonin group (T/D+20,50 and 100 mg/kg melatonin). For the histological...

Provedor de dados: 77
Autores: Carrasco,Vanessa; Martínez,Cristián; Silva,Héctor; Collipal,Erika; Campos,Christian; Silva,Tamara.
Obesity is a prevalent disease in Chile. The multitude of cause factors makes it a complex disease and therefore very difficult to treat, since its roots lie in the earliest stages of life. We evaluated pupils from 21 municipalized primary schools, in rural and urban communities from the 10 districts of the IX Region. The sample consisted of 275 subjects in Kindergarten and first year primary school in the year 2008, who were monitored over two years. The results show a trend indicating an increase in the prevalence of obesity in the sample, the difference being statistically significant, p=0.000. These results show that obesity is increasing, and that more action is needed to slow this disease occurring from early childhood.

Atresia of the Coronary Sinus Ostium to the Right Atrium with a Persistent Left Superior Vena Cava
Provedor de dados: 77
Autores: Caetano,Abadio Gonçalves; Ribeiro,Tiago Coelho; Filho,Omar Andrade Rodrigues; Fazan,Valéria Paula Sassoli.
The coronary sinus has lately assumed an important role in the cardiologic clinic once it has been widely used in invasive procedures of the heart. Commonly, it is used during the electrodes implants for the epimiocardic monitoring of the cardiac rhythm, through a biventricular pace maker. These invasive procedures are not possible in hearts with an atresic coronary sinus ostium. In the presence of this anomaly, another may occur: the development of the "Marchal" vein which is a remaining of the left superior vena cava (LSVC). This happens so that the venous blood from the heart can drain into the right atrium, by a communication between the LSVC and the left brachiocephalic vein. The presence of a LSVC brings difficulties when performing an invasive...

Autores: Núñez Chichet,M E; Genovese,P; Bielli,A.
The vomeronasal organ (VNO) is a tubular chemoreceptory organ which detects environmental pheromones and is essential for mammalian normal reproductive activity. A sensitive chemoreceptory neuroepithelium lines the concave VNO wall and the opposite, convex wall is lined by a seudostratified, receptor-free epithelium. The secretion of the Jacobson glands (JG) -tubuloacinary glands lying in the lamina propia of the VNO - is essential for pheromones contacting vomeronasal organ chemoreceptors. Tubuloacinary glands lying in the connective tissue of the nasal septum mucosa (Bowman glands), can be classified as ventral and dorsal, according to their location. Positivity to PAS and Alcyan blue reactions and androgen receptor immunolocalization was evaluated with...

Provedor de dados: 77
Autores: Anu,Vinod Ranade; Rajalakshmi,Rai; Latha,Venkatraya Prabhu; Mangala,Kumaran.
An unusual presentation of the duplication of thoracic duct with a rare lymphatico- venous communication was found during the routine dissection for undergraduate students. The thoracic duct duplicated at the level of T12 vertebra. Normally thoracic duct opens into the junction of left internal jugular vein and subclavian vein. On the right side of the neck, the right lymphatic duct conveys the lymph from the head and neck, the upper extremity and the right side of the thorax to the right innominate vein. Here, the duplicated thoracic duct on the left side opened directly into the inferior vena cava. The above case is discussed with regard to its development, incidence, and clinical significance

Autores: Manterola,Carlos; Otzen,Tamara.
Uno de los mayores dilemas en investigación es la ocurrencia de errores, los que pueden darse por efecto del azar o de forma sistemática. Es así como, se puede considerar que existe sesgo cuando en el curso de una investigación se comete un error de forma sistemática, es decir no aparece como un hecho aleatorio o por efecto del azar. Los sesgos pueden ocurrir por un sinnúmero de causales; pero en términos generales, se acepta que los más frecuentes y quizás los de mayor relevancia son aquellos debidos al observador, a lo que se observa y a aquello con lo que se observa. Dicho de otra forma, el que mide, lo que se mide y con que se mide. Otro considerando a tener en cuenta es que un sesgo puede ocurrir en cualquier etapa del curso de una investigación,...

Provedor de dados: 77
Autores: Rai,Rohan; Rai,Ashwin R; Rai,Rajalakshmi; Bhat,Keshav; Muralimanju,B. V.
Disturbance in the organogenesis of tongue might lead to some malformations like tongue tie, bifid tongue and hairy tongue. Severe degrees of these anomalies may cause speech impairment or periodontal defects. The present study was done on patients of the southern coastal belt of India during the past two years, on gross tongue anomalies. The results of the present study reveal that occurrence of tongue tie is 0.2% and bifid tongue is 0.3% in the southern coastal population. Since great majority of these oral anomalies have genetic basis the purpose of the present report is to highlight that these anomalies can exist without any familial background and also to suggest that environmental factor may play a role in the etiogenesis of these anomalies.

The Role of Antioxidants in Cerebellar Development: A Review of Literature
Provedor de dados: 77
Autores: Imosemi,I. O.
Developmental pathologies may result from endogenous or xenobiotic-enhanced formation of reacting oxygen species (ROS), which oxidatively damage cellular macromolecules and/or alter signal transduction, and that the embryonic processes regulating the balance of ROS formation, oxidative DNA damage and repair, and ROS-mediated signal transduction may be important determinants of teratological risk. ROS can oxidize molecular targets such as DNA, protein, lipid in a process called oxidative stress resulting in cellular dysfunction and in utero death or teratogenicity. This review, consisting of literature search of journals and chapters in books aims at highlighting the importance of the cerebellum in controlling various motor activities in the body, as well...

During the routine dissection, a rare anomaly was observed in left lower limb of a female cadaver. The external iliac artery continued as femoral artery, branched on lateral side as the lateral circumflex femoral artery and on medial side as profunda femoris artery. On tracing the lateral circumflex femoral artery, the ascending branch towards the spinous anastomosis was very thin and coursed behind the rectus femoris muscle. The transverse and descending branches were not observed, however, the artery coursed along the vastus lateralis towards the knee. The femoral artery had its normal course and continued as popliteal artery. The profunda femoris artery originated from the medial side of the external iliac artery, initially superficial to the femoral...

The First Metacarpal is the Thumb First Phalange: EvoDevo Implications
Provedor de dados: 77
Autores: Valenzuela,Carlos, Y; Berríos-Loyola,R; Canals,M.
We examined the status of the first metacarpal bone whose shape, fetal and post-natal development correspond to those of the thumb proximal phalanx. Galen already described this, circa 170 CE. Our radiographic data confirm that the pre-axial (radial or anterior) side of the hand matures, later than the post-axial (ulnar or posterior) side, both, pre- and post-natally. A new perspective on thumb primate and human ontogeny is discussed and comparative observations on the Evolutionary Development (EvoDevo) of the thumb and the first toe are proposed along with a nomenclature honoring Galen's original proposition.

Provedor de dados: 77
Autores: Mahajan,Anita; Rana,K. K; Saha,S.
Anatomical variations in the region of axilla and pectoral region are very common. These variations need attention to avoid complications arising during surgeries and diagnostic and interventional invasive procedures in this region such as surgeries for breast carcinoma, venous access during central venous line, pacemaker and cardiac defibrillator implantation etc. During routine cadaveric dissection we had noticed a rare variation of axillary vein and artery. In this case axillary vein, just deep to the inferior border of pectoralis minor was pierced by the lateral thoracic artery, a branch of axillary artery. Perforation of the axillary vein by a branch of the axillary artery is extremely rare variation encountered till now. We report a variation wherein...

Autores: Yuan,Guoqiang; Pan,Yawen; Li,Haiyan; Wang,Jianlin.
Vascular endothelium play an essential role in regulating endothelial functions by maintaining normal vascular tone, modulating hemostasis, and preventing thromobogenesis. The aim of present study was to reveal ultrastructure features of coronary artery endothelium in Bactrian Camels by means of scanning electron microscope (SEM) technology. The results showed that the endothelial cells distribute along the direction of blood flow. Their morphology and protuberant degree towards luminal surface vary for different parts of the coronary artery. The luminal surface of a.c oronaria sinistra and a. coronaria dextra was covered by impaired and intact endothelium, respectively. Platelets and leukocytes sticking to the endothelium were found.

This paper aims to verify the effects of severe protein malnutrition over the intestinal ascending colon morphometrics in adult rats. 12 rats (90 days old) were divided into 2 groups: control (n = 5) and malnutritioned (n = 7). In the following 90 days, the rats of the control group received a 24% protein chow as the malnourished group received 4% protein chow. The animals were submitted to euthanasia according to the anesthetic protocol. Colon segments were collected and submitted to routine histological processing. The cuts were stained with HE and histochemical techniques for mucines. The morphometric analyses showed the sustenance of the whole wall and muscle tunic thickness, as well as the reduction of the thickness of the mucosa tunic, the amount of...

The stereoscopic morphology of the iliofemoral, pubofemoral, and ischiofemoral ligaments in hip joint is hard to understand, either in anatomy books or from cadaver dissection. To aid in understanding, three-dimensional models were built from the sectioned images of cadaver hip, which demonstrate fine components better than CTs and MRIs. In the female data of Visible Korean project, the ligaments and neighboring structures were recognized and outlined in detail. Successively, the outlines were stacked and reconstructed to manufacture their surface models by using the sophisticated computer method. The surface models were overlapped with the original sectioned images, which enhanced comprehension of the hip joint anatomy. With the surface models, hip joint...

The mosquito midgut is the organ into which the blood meal passes and in which, within a peritrophic membrane secreted by the epithelium, the blood is retained during digestion and absorption. The mosquito midgut is lined with an actin filled microvilli that are exposed to the harsh environment of the gut lumen such as food particle abrasion, digestive hydrolases and attack by pathogens and parasites that are taken in by the blood meal. These microvilli are protected them these effects by the peritrophic matrix, the glycocalyx and the mucin proteins that line their epithelial surfaces. Immunization of BALB/c mice with AgMUC1/IL-12 cDNA has been shown to kill mosquitoes when fed on these mice. Mucin is one of the proteins produced in the mosquito midgut...

Immunohistochemical Localization of Estrogen Receptor in the Embryonic Gonad of Male Quail Embryo During Gonadal Differentiation
Provedor de dados: 77
Autores: Intarapat,Sittipon; Sailasuta,Achariya; Satayalai,Orawan.
In birds, male embryo the gonads develop bilateral testes, in which both left and right sides produce functional spermatozoa, whereas female embryo, only the left gonad develops into a functional ovary. Estrogen plays a key role in avian sex determination in both sexes by binding to the estrogen receptor (ER). Surprisingly, chicken estrogen receptor (cER) mRNA is expressed in both sexes; moreover; its expression is only expressed in the left male gonad. The present study aimed to localize ER protein in the left gonad of male quail embryo using immunohistochemistry. The 8-day-old male quail embryos whose embryonic sex distinguished by gonadal morphology were studied. Histology of the left male gonad displayed thin cortex containing 1 to 2 layers of the...

The current annual consumption of insecticides in agriculture in Brazil is over three million tons. The exposure happens through food that is contaminated with toxic waste and respiratory and dermal absorption. Biological control with Bacillus thuringiensis Berliner (Bt) has assumed increasing importance replacing the use of conventional insecticides. However, the tests used to justify approval for use and market release of Bt products, and the protocols used to assess the development of toxicity, are extremely superficial. In addition, more studies comparing effects between males and females and during pregnancy and lactation have not been conducted. Thus, the hypothesis tested in this study was if the administration of the XenTari® WG (Bacillus...

Estudios previos demostraron que la morfología del acromion y sus respectivas relaciones con el tubérculo supraglenoideo y el proceso coracoides, son de fundamental importancia en la determinación del espacio subacromial. Las variaciones de estas estructuras pueden provocar el principio del síndrome del impacto, también conocido como síndrome del pinzamiento del espacio subacromial. Sin embargo, se observa la falta de relatos en la literatura sobre los diferentes padrones morfométricos del acromion. El objetivo de este estudio fue establecer un padrón morfométrico del acromion, a través de la determinación de su largo, grosor y proyección anterior, además de determinar su relación con el proceso coracoides y el tubérculo supraglenoideo. Fueron analizadas...

Autores: Hipkaeo,Wiphawi; Kondo,Hisatake.
In embedment-free transmission electron microscopy without employing epoxy embedding media, the cytoplasmic matrix, in which cell organelles and elements including the cytoskeletons are held in place, lattices of strands are clearly and constantly disclosed in every cell. Their compactness is variable in different kinds of cells and in different domains of one and the same cell, and it is changeable under hypo- or hyper-osmolarity. In addition, the appearance of strand-lattices is duplicable in artificial proteins at different sol/gel states and concentrations. All taken together, a new and probable ultrastructural criteria has been proposed for identification of cytoplasmic sol/gel states with a hope that the dynamic properties of the cell is understood...

La leucemia linfoblástica aguda (LLA), es la neoplasia mas frecuente en la población infantil. Se manifiesta por una perdida de diferenciación de progenitores linfoides produciendo un aumento de células inmaduras. La hipermetilación en la región promotora de genes supresores de tumores (GST) puede producir un silenciamiento génico que le proporciona a la célula leucémica una ventaja proliferativa o la previene de la apoptosis. Se estudia el estado de hipermetilación de 4 GST involucrados en la apoptosis: APAF1, ASPP1, p73 y FHIT y su asociación con la sobrevida de pacientes menores de 15 años con diagnóstico de LLA.

Células Troncales en el Desarrollo y las Perspectivas de Reprogramación Celular para la Regeneración
Provedor de dados: 77
Autores: Muñoz,L; Concha,M. L.
Los organismos multicelulares se desarrollan a partir de una sola célula: el cigoto. A lo largo de su ontogenia, las células que derivan del cigoto despliegan distintos programas celulares, los cuales son estabilizados por mecanismos epigenéticos. Los programas de las células troncales son más inclusivos, siendo mayor el silenciamiento que la activación de genes durante el proceso de diferenciación celular. Experimentalmente, se ha logrado que células en estado de diferenciación terminal reactiven el programa de células troncales y recuperen su pluripotencialidad, proceso llamado reprogramación. Esto despierta esperanzas en el avance de una medicina regenerativa con nuevas capacidades para el tratamiento de enfermedades crónicas, sin las restricciones...

Provedor de dados: 77
Autores: Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
In forensic medicine, diagnosis of sex is the first step in the identification of human skulls. A first approximation is carried out via the qualitative analysis of a series of morphological indicators of sexual dimorphism. Classical studies (Krogman &amp;amp; Iscan, 1986) described 14 indicators for the diagnosis of sex with an accuracy of 90%, and one of these indicators is the shape of the palate. This study analyzed the effect of the loss of teeth on the accuracy of the diagnosis of sex in Brazilians adult skulls, using the shape of the palate as an indicator. We used 98 skulls of adult Brazilians, comprising 35 females and 63 males with an average age of 39.3 years (SD 7.8). The skulls were classified into two groups, namely the fully edentulous...

La parotidectomía es un procedimiento quirúrgico habitualmente realizado por Cirujanos Maxilofaciales y Cirujanos de Cabeza y Cuello, en el cual se remueve parcialmente o en su totalidad a la glándula parótida. Las indicaciones más comunes para éste procedimiento son las neoplasias de la glándula. Aproximadamente el 80% del total de los tumores de glándulas salivales ocurren en la parótida. De estos, el 75-80% son de naturaleza benigna. Sin embargo, la parotidectomía es un procedimiento sumamente complejo debido a la anatomía regional y por la íntima relación de la glándula parótida con el nervio facial. Siendo la clave de este procedimiento la preservación funcional de éste nervio y de sus ramos. Por lo tanto el conocimiento acabado de la anatomía de la...

Knowing the dimensions of the vertebral elements is very important for the development of instrumentation related to the cervical spine. Ethnic variations have been reported in these dimensions and, to date, there have been no morphometric studies of this area performed on the Mexican population. We conducted a morphometric study of 150 cervical vertebrae (C3-C7) obtained from a northeastern Mexican population to determine the dimensions of the bodies, pedicles, laminae, spinous processes, and superior and inferior articular processes. We did not find significant differences (p&lt;0.05) in measurements taken of the left and right sides. The dimensions of the vertebral bodies were larger at lower levels. The pedicles of the C3 vertebra were larger in all...

Scapula has three margins and angles and located posterolateral of thorax. One of the anatomical structures of scapula is suprascapular notch located medial to coracoid process base. Suprascapular notch can be seen in different shapes and depths. Suprascapular notch is surrounded by transverse scapular ligament which is a short and strong ligament. Suprascapular notch creates an osteofibrosis passage with this structure within suprascapular nerve passes. It has been reported that this osteofibrosis structure can intirely or partially ossify. All lesions of nerves occured in course as result of exposure to compression, tension and bending are called entrapment neuropathy. Like other peripheral nerves, suprascapular nerve can be exposed to compression while...

Tissue engineering (TE) has become an alternative for auricular reconstruction based on the combination of cells, molecular signals and biomaterials. Scaffolds are biomaterials that provide structural support for cell attachment and subsequent tissue development. Ideally, a scaffold should have characteristics such as biocompatibility and bioactivity to adequate support cell functions. Our purpose was to evaluate biocompatibility of microtic auricular chondrocytes seeded onto a chitosan-polyvinyl alcohol-epichlorohydrin (CS-PVA-ECH) hydrogel to propose this material as a scaffold for tissue engineering application. After being cultured onto CS-PVA-ECH hydrogels, auricular chondrocytes viability was up to 81%. SEM analysis showed cell attachment and...

Autores: Karau Bundi,P; Ogeng´o,J. A; Hassanali,J; Odula,P. O.
Atlas bridges, the bony outgrowths over the third segment of the vertebral artery are associated with compression of the artery and nerves. There are limited studies comparing morphometry of the complete atlas bridges and that of the ipsilateral transverse foramen. Bilateral and gender differences in the morphometry of the complete bridges remain relatively unexplored. One hundred and two atlas vertebrae (49 male and 53 female) obtained from the Osteology Department of the National Museums of Kenya were used for this study. The presence of complete posterior atlas bridge (retroarticular canal) and lateral bridge (supratransverse foramen) was noted. Measurements were taken for the diameters of foramina, and the ipsilateral transverse foramina and their...

Autores: Cornejo U,Ricardo.
Las células mantenidas en cultivo que conservan sus características propias, constituyen un excelente modelo para el estudio de las modificaciones fisiológicas, morfológicas y morfométricas que caracterizan el proceso biológico de la transformación celular. La línea HC11 corresponde a células de epitelio mamario de rata, normales, mantenidas en cultivo, las cuales estimuladas a proliferar con factor de crecimiento epidérmico originan el grupo celular HC11 GM. Cuando estas células normales y proliferantes son transfectadas con el oncogen ras, se determina la generación de un tipo celular transformado, el cual por efecto de las sucesivas mitosis deriva en el grupo celular HC11ras. Estudios de microscopía electrónica, morfológicos y morfométricos permiten...

Autores: Smane,Liene; Pilmane,Mara.
Cleft lip and palate (CLP) is a congenital anomaly characterized by the inappropriate fusion of the upper lip, alveolus, and secondary palate. This study investigated whether expression of interferon regulatory fac tor 6 (IRF6), receptor-like tyrosine kinase (RYK), and paired-box 9 (PAX9), which are essential for the normal development and morphogenesis of craniofacial structures, is dysregulated in children with CLP. Oral mucosa tissue samples were obtained from patients with complete bilateral (CB) CLP (n= 19) during corrective plastic surgery and unaffected control subjects (n= 7). IRF6, RYK, and PAX9 expression was assessed by immunohistochemistry, and data were analyzed with the Mann-Whitney test. In patients, IRF6 immunoreactivity in the connective...

Correlaciones Morfológicas entre la Forma de la Cabeza, Dieta y uso de Hábitat de Algunos Sceloporus de México: Un Análisis Cuantitativo
Provedor de dados: 77
Autores: Galindo-Gil,Sandra; Rodríguez-Romero,Felipe de Jesús; Velázquez-Rodríguez,Alma S; Moreno-Barajas,Ruth.
La relación entre los caracteres morfológicos y la ecología de los organismos permite deducir respuestas adaptativas. Estas adaptaciones son el resultado de presiones selectivas que actúan sobre los organismos, así como el tipo de presa que consumen o el ambiente en el que se encuentran. De esta manera, los organismos exhiben morfologías que les permiten explotar los recursos disponibles. Sceloporus es un grupo de lagartijas altamente diverso en Norteamérica además de encontrarse en diversos hábitats, lo que lo hace un modelo óptimo para probar hipótesis adaptativas y evolutivas. El objetivo fue evaluar si existen diferencias morfológicas en la cabeza de algunas especies de Sceloporus y determinar si dicha morfología surge como una respuesta adaptativa al...

Dextrocardia and Situs Inversus Totalis in a Nigerian Cadaver: A Case Report of Rare Anomaly
Provedor de dados: 77
Autores: Ofusori,David A; Okwuonu,Christina U; Ude,Raymond A; Adesanya,Olamide A.
This report describes an adult male cadaver with dextrocardia and situs inversus totalis in a Nigerian cadaver. The photographic illustrations revealed transposition of some of the visceral organs such that the stomach and spleen were located on the right and the liver and gall bladder on the left. Also, the left lung was tri-lobed while the right was uni-lobed. The heart was flattened and flipped to the right thus, transposing the great vessels. The report showed that dextrocardia and situs inversus exists amongst Nigerians and possibly Africans and therefore wish to recommend early medical examination since patients with this condition are unaware of their unusual anatomy until they seek medical attention for an unrelated condition. Early detection may...
