The aim of this study was to evaluate the effects of maternal protein and energy restriction during lactation on mandible dimensions of pups (female) at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23% protein, 2) protein-energy restricted group (PER) - free access to an isoenergetic, protein-restricted diet containing 8% protein, and 3) energy-restricted group (ER) ­ fed with restricted amounts of a standard laboratory diet. At weaning (d21), all pups were separated of dams and received free access to a standard laboratory diet containing 23% protein until 90 days (d90), when the rats were anesthetized and sacrificed. The dimensions of...

A Comparative Study of Variation of the Pterion of Human Skulls from 13th and 20th Century Anatolia International Journal of Morphology
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...

Morphometric Study of the Proximal Femur Extremity in Brazilians International Journal of Morphology
de Sousa,Eduardo Branco; Fernandes,Rodrigo Mota Pacheco; Mathias,Marcelo Bezerra; Rodrigues,Mauro Roberto; Ambram,Albert James; Babinski,Marcio Antonio.
Brazilian populational aging besides higher life expectancy has increased the incidence of proximal femoral fractures. Treatment of those fractures uses implants which are based in measurements performed in caucasians, including the 135 degrees cervical-diaphyseal angle. Knowing femoral morphometry allows evaluating implants adequability. We performed our study using 110 Brazilian human femurs (49 right and 61 left). We excluded from the study: bones submitted to osteosyntesis, to prosthetization or those showing abnormalities or malformations which could affect its structure and shape. Bones were submitted to roetgenographic analysis and the images were scanned and transferred to personal computer. Measurements were obtained by AutoCad software and...

Effects of Aspartame on Fetal Kidney: A Morphometric and Stereological Study International Journal of Morphology
Martins,Marielza R Ismael; Azoubel,Reinaldo.
The objective of this study was the evaluation of aspartame effects on morphometric alterations of the glomerulus, proximal and distal convoluted tubules and collecting ducts of the rat fetal kidney during organogénesis. Fifteen pregnant rats averaging 24 g body weight, were divided into 3 groups (n=5 each) of controls, rats treated with aspartame exposed to room temperature and rats treated with aspartame heated to 40°C. Animals were given 14mg / kg aspartame by the intragastric route on the 9th, 10th, and 11th days of pregnancy. Karyometric and stereological techniques estimated morphological changes. A significant decrease of fetal body weight was observed in the group given aspartame kept at room temperature, compared to controls. Karyometry permitted...

An Osteometric Evaluation of the Mandibular Condyle in a Black KwaZulu-Natal Population International Journal of Morphology
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...

Pre-Operative Measurement of the Morphometry and Angles of the Anterior Clinoid Process (ACP) for Aneurysm Surgery International Journal of Morphology
Cecen,Aycicek; Celikoglu,Erhan; Is,Merih; Cetiner Kale,Aysin; Torum Eroglu,Basak.
The anterior clinoid process (ACP) is proximal to vital structures, such as the optic nerve, internal carotid artery and ophthalmic artery; therefore, study of its anatomy is important in guiding and defining surgery. We studied the anatomical structure of the ACP, including the angle formed by the apex of the ACP triangle, and its orientation, to provide information for easier and safer surgery. The measurement was performed on the axial planes of 242 cranial computerized tomography (CT) scans and 27 adult Turkish skulls of both sexes. The length of the ACP, width of the ACP at its base, the angle formed by the apical angle of the ACP triangle and the orientation of the ACP defined according to the sagittal midline were examined. In the Turkish skulls,...

The Morphometry of the Angle of Mandible and its Correlation with Age and Sex in the eThekwini Metropolitan Region: A Panoramic Study International Journal of Morphology
Pillay,S; Ishwarkumar,S; De Gama,B.Z; Pillay,P.
The angle of mandible is formed by the tangent line joining the posterior margin of the ramus and the base of the mandible. The angle of mandible has population-specific characteristics therefore; it is imperative to the field of forensic anthropology for age and sex determination. Literary reports regarding the use of the angle of mandible for age and sex determination vary, as some studies support it, while other studies have documented inefficiencies. Therefore, the aim of this investigation was to document the morphometry of the angle of mandible and to determine if a correlation between the angle of mandible, age and sex exists. Sixty four digital panoramic radiographs (n=128) of individuals between 16-30 years were morphometrically analysed using the...

An Osteometric Evaluation of the Jugular Foramen International Journal of Morphology
Ishwarkumar,S; Naidoo,N; Lazarus,L; Pillay,P; Satyapal,K. S.
The jugular foramina (JF) are bilateral openings situated between the lateral part of the occipital bone and the petrous part of the temporal bones in the human skull. It is a bony canal transmitting neurovascular structures from the posterior cranial fossa through the base of the skull to the carotid space. Since the JF depicts variations in shape, size, height and volume between different racial and gender groups, along with distinctive differences in laterality from its intracranial to extracranial openings, knowledge of the JF may be necessary to understand intracranial pathologies. Therefore, the purpose of this study was to evaluate the morphometric measurements of the jugular foramen. Various morphometric parameters of the JF and its relation to...

A Quantitative Assessment of the Morphological Characteristics of BeWo Cells as an in vitro Model of Human Trophoblast Cells International Journal of Morphology
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...

Anthropometry of the Black Adult Tibia: A South African Study International Journal of Morphology
Naidoo,N; Lazarus,L; Ajayi,N. O; Satyapal,K. S.
The tibia is the medial long bone of the leg and is characterized by a shaft and two expanded extremities. Despite the recent advent of tibial bone graft harvesting, the tibia has also been confirmed to be of great forensic significance. As this appears to be the only tibial dry bone study done in Southern Africa, this study aimed to investigate morphological and morphometric parameters that are of clinical and anthropometric importance. Morphological and morphometric examination of 302 adult tibial bone specimens of Black South Africans obtained from the osteological bank of the Discipline of Clinical Anatomy at the University of KwaZulu-Natal was performed. The sample consisted of 168 males and 134 females with an age range of 15 to 87 years old. The...

The Mexican government passed a new reform of article 11 of the General Law in 2014 regarding Women's Access to a Life Free of Violence, which states that a cesarean section may not be performed if a vaginal birth is viable. Cesarean sections are excessively indicated in Northen Mexico, using the diagnosis of cephalopelvic disproportion due to a narrow pelvis. Currently, there is no standardized morphometry of the female pelvis in a Mexican population to establish adequate diagnostic parameter. Our study measures the pelvic diameters of the birth canal using abdominopelvic computed tomography (CT). Two hundred and ninety CT from Mexican women between the ages of 18 and 50 were collected and 3D reformatted in order to morphologically measure the pelvic...

Extraocular muscles are important references in strabismus surgery and in placement of intraorbital devices. We analyzed extraocular muscles morphometry and possible anatomical variances of 20 orbits. We report the length, width, and points of insertion of the extraocular muscles. No anatomical variations in length, width and points of insertion were found. With regard to the rectus muscles, it was found that the superior rectus and lateral rectus are the longest muscles and that the width difference between the superior and inferior rectus is greater than that between the medial and lateral rectus and that the point of insertion of the rectus muscles has a variable morphology. The superior oblique muscle was smaller in caliber than the inferior oblique,...

Ribas,Paulo; Lopes,Ruberval A.; Sala,Miguel A.; Ribas,Lucia M.R.; de Mattos,Maria da Glória C.; Semprini,Marisa; Watanabe,Ii-Sei; Regalo,Simone C.H..
Cadmium in the air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cadmium affects placental functions, can cross the placental barrier and directly disturbs fetal development. It is also excreted into milk. The organism is particularly susceptible to cadmium exposure at perinatal period. The effect on rat maxillary molar junctional epithelium a continuous exposure to drinking water containing low level of cadmium during lactation was studied. Female rats received drinking water ad libitum containing 300 mg/l CdCl2 throughout the whole lactation. Control animals received a similar volume of water without cadmium.
