Variaciones morfo-anatómicas de seis especies a lo largo de un gradiente altitudinal en el Cerro Tláloc, Estado de México.
Provedor de dados: 32
Autores: Jiménez Noriega, Mayte Stefany.
Las condiciones ambientales asociadas a gradientes altitudinales inducen modificaciones de las características morfo-anatómicas de las especies que ahí se encuentran. Las variaciones morfo-anatómicas en regiones intertropicales han sido poco documentadas. Se espera que los patrones relacionados con estos gradientes altitudinales serán similares a aquellos registrados en regiones fuera de la zona intertropical. Se estudiaron seis especies (Acaena elongata, Alchemilla procumbens, Geranium seemannii, Lupinus montanus, Ribes ciliatum y Symphoricarpos microphyllus) que se distribuyen en el gradiente altitudinal del Cerro Tláloc, Estado de México con el objetivo de reconocer y evaluar las modificaciones morfo-anatómicas asociadas al gradiente. Se recolectaron...

Provedor de dados: 32
Autores: Rangel Fajardo, María Alma.
La adquisición de tolerancia a la desecación en semillas ortodoxas es una estrategia adaptativa  que no presentan las semillas del tipo recalcitrantes y por consiguiente son sensibles a la  desecación. El grado de tolerancia o sensibilidad a la desecación se ve afectada por varios  aspectos de origen genético, fisiológico, bioquímico y anatómico; por consiguiente existen  diferencias entre genotipos y entre individuos dentro del genotipo de la misma especie. En este  estudio se documentaron características de anatomía de las semillas de cacao, se midió el grado  de tolerancia a la desecación y la acumulación de azúcares en relación con tolerancia a la  desecación en poblaciones de tres orígenes genéticos de cacao (Theobroma cacao L.). Se  emplearon los...

Autores: Navarro-Cerrillo,Rafael Mª; Santelices,Rómulo; Ruiz Rodríguez,Alberto; Cabello Lechuga,Angel.
Nothofagus alessandrii is an endangered species that is endemic to the Mediterranean area of Chile. There is no information on the anatomical structure of its seeds and there are few studies on the morphometric and germination differences between its populations. Therefore, the purpose of this study was to describe the morpho-anatomical structure of seeds of N. alessandrii in order to compare the morphology and germination four geographically distinct populations. This was done by selecting seeds of four different origins covering the entire latitudinal distribution of the species and measuring their size, shape, dry weight and germination in order to perform a comparative analysis. Results showed that the anatomical structure of N. alessandrii seeds is...

Ciclo biológico de Simpulopsis ovata (Gastropoda, Bulimulidae) em São Francisco de Paula, Rio Grande do Sul, Brasil
Provedor de dados: 76
Autores: Gomes,Suzete R.; Silva,Rosane S. da; Gil,Guacira M.; Thomé,José W.
The population growth of Simpulopsis ovata (Sowerby, 1822) from the Centro de Pesquisas e Conservação da Natureza - Pró-Mata, São Francisco de Paula, Rio Grande do Sul, Brazil, was studied along eleven months of 1996. Two discontinuous age classes were identified. The first one, with a monthly growth rate of 1.55 mm, was reproductively mature during April and May. The second one appeared after the previous group and had a monthly growth rate of 0.44 mm. The fact that no adults from the two age classes were found together is a characteristic of a semelparous species. New insights about its shell, pallial cavity and reproductive system are given. This is the first record of S. ovata for the State of Rio Grande do Sul.

Investigation of marine bivalve morphology by in vivo MR imaging: first anatomical results of a promising technique
Provedor de dados: 5
Autores: Pouvreau, Stephane; Rambeau, Marc; Cochard, Jean-claude; Robert, Rene.
Classically, investigation of the internal morphology and composition of molluscs and especially bivalves relies on destructive method (biometry, biochemistry and histology). These techniques have given essential information, but in contrast are time consuming and lead to the irreversible loss of the animal while they don't allow integration of the various levels of molecular-to-organism functioning. The aim of this study is to analyze for the first time the potential of NMR (nuclear magnetic resonance) imaging (MRI) to depict, with sufficient resolution and satisfactory contrast, the anatomy of a bivalve model, the Pacific oyster, Crassostrea gigas, without opening it. MRI experiments were carried out at 19 °C in several non-anaesthetized adult Pacific...

Évaluation des potentialités de l'IRM pour la recherche sur la Physiologie des Bivalves Premiers résultats anatomiques et perspectives
Provedor de dados: 5
Autores: Pouvreau, Stephane; Davenel, A; Quellec, S; Rambeau, M.
Nuclear Magnetic Resonance (NMR) is increasingly used in biology and the appearance of imaging and structural and/or metabolic spectroscopy (MRI/MSR) platforms (Rennes, Strasbourg, Marseille...) devoted to this small animal shows the recent keen interest in these research techniques. However, to this day and to our knowledge, no approach of this style has been developed for sea molluscs and even less so for the cup oyster, Crassostrea gigas. Because of its economic importance, this bivalve mollusc is the subject of much research in physiology, to the point of becoming, at IFREMER, a biological model for marine invertebrates. Nonetheless, most of the methodologies developed for studying it are destructive, which (1) prevents individual follow-up, (2)...

Sanitation with sponge and plunger: western Atlantic slit-wormsnails (Mollusca : Caenogastropoda : Siliquariidae)
Provedor de dados: 5
Autores: Bieler, R.
Siliquariid Tenagodus (synonym: Siliquaria) snails are obligatory sponge commensals, with uncoiling and laterally slitted shells embedded inside Demospongiae hosts, and shell apertures facing the outside allowing for respiratory and gill-filter-feeding activities. Live-collected animals observed in situ within hosts provide the first detailed functional morphological study of the group, and form the basis for systematic revision of the western Atlantic members of type genus Tenagodus (Siliquariidae, synonym: Tenagodidae). Three species are recognized. Overall anatomical features of wide-ranging Atlantic T. modestus (Dall, 1881) and T. squamatus (de Blainville, 1827) [ = T. anguillae Morch, 18611 are similar to those previously described for New Zealand...

Etude morphologique du loup Dicentrarchus labrax L. de la region de Sete
Provedor de dados: 5
Autores: Barnabe, Gilbert.
Sampling of a population of D. Labrax was one with spear diving catches. Morphometric and meristic data were used to calculate a biometric index. This index showed that all the bass of the Sete area belong to Dicentrarchus labrax, even if they were black spotted on the upper part of the body. Morphology was slightly different according to sex, but sex determination was not always possible using morphometric data. This inshore population shows some morphological characteristics (branchiospine and lateral line scale number) different from the data collected on the same sp along the Maroc Atlantic coast by Gravier, 1961.

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...

Autores: Khokhlov,R. YU.; Kuznetcov,S. I.
The authors have used non-laying and laying hens (Lohmann Brown), in order to study morphological aspects development of tunica mucosa of the oviduct. The results showed that the oviduct of the hen is well-developed at the left side, atrophied at the right side and consists of five different regions: infundibulum, magnum, isthmus, shell-gland and excretory section (vagina). During 1-120 days in oviduct is the most advanced caudal part, where height and width folds of a tunica mucosa is more than in cranial part, that probably, is caused with the future function of these departments. In the period oviposition (150-540 days), the tunica mucosa is most advanced in such departments, as: magnum, isthmus, shell-gland

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...

Autores: Macéa,José Rafael; Fregnani,José Humberto Tavares Guerreiro.
For adequate treatment of patients with breast cancer, mastologists should have a complete understanding of the anatomy of the thoracic wall, axilla and breast. However, the classical anatomical descriptions in textbooks make it difficult to gain full mastery of this subject, because the books usually deal with its elements separately. In an endeavor to resolve this difficulty, the present authors have conducted an extensive review, to describe the muscles, blood vessels and nerves of the thoracic wall and in the axilla that are of interest to mastologists. The axilla was described in detail, with emphasis on its limits, walls and contents, and highlighting the lymph nodes in this region. Finally, the anatomy of the breast and its topography, innervation,...

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.

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: Ayres de Vasconcellos,Henrique; Barros de Vasconcellos,Pedro Henrique.
The historical references are taken from Aristoteles (384-322 a C) considered the father of Kinesiology, and Claudius Galenus from Pergamon (131-201), the first team doctor. Both men&amp;acute;s studies shared the same objective: functional-anatomic aspects related to the Locomotive System. Although there were several descriptive anatomic studies of bones and muscles, it was Andreas Vesalius (1514-1564), whom most significantly contributed to the development of a new methodology for the lectures of Anatomy, with the setting up of skeletons and dissection of bodies during his lessons. Objectives: the aim of this paper is study the description of bones and muscles from the Vesalius works. We search Vesalius&amp;acute;s publications, specially "De Humani...

A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals
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.

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.

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...

Autores: Kim,Maru; Oh,Seong-Taek.
Laparoscopic surgeries were first introduced in the 1980s. More recently, similar techniques such as natural orifice transluminal endoscopic surgery and other advanced transumbilical surgeries have been developed. With all of these surgical advances, basic information about the umbilicus is lacking. This study evaluated the relationship between umbilical diameter and thickness, as well as the underlying vessels, in order to develop a simple means of assessing umbilical anatomy. We retroactively reviewed 842 computed tomography images that included the umbilicus. Umbilical thickness, diameter, type of vessel located beneath the umbilicus, depth to the vessel, and other parameters were measured. Age and sex were noted, and their relationship was analyzed as...

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

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...

Origin of the Tendon of the Long Head of the Biceps Brachii Muscle and its Relationship with Glenoid Labrum in Human Foetuses
Provedor de dados: 77
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.

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. The aim of this study is to analyze the incidence of...

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...

Tibial collateral ligament by virtue of its length, composite attachments, and biomechanical exertions is more prone to lesions. A systematic analysis of the dimensions and variations of this ligament has been presented in this article. With the decrease emphasis on anatomy as a preclinical subject and recent successful moves to curtail total teaching hours for dissection, coupled with the increasing shortage of cadavers, data of this nature will in our opinion becomes scarce progressively. With these factors in context, and attempt is made to record the gross morphological features of the ligament from a series of dissections

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...

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: Alves,Nilton; Laino Cândido,Paulo; Frazão,Renata.
The pronator quadratus is the main muscle responsible for pronation of forearm, helped by the pronator teres. To study the innervation of the pronator quadratus, eighteen forearms from a formol fixed corpses were dissected. We examined the relationship between the anterior interosseous nerve and the pronator quadratus. The wrist articular line was used as reference point. The branch which had the most proximal penetration into the pronator quadratus was 5.4 cm above the wrist articular line in a right forearm and 5.6 cm in a left one, and the branch which had the most distal penetration was 2.5 cm above the wrist articular line in a right forearm and 2.4 cm in a left one. The length of the anterior interosseous nerve and the width of the pronator quadratus...

Quantitative Anatomy of the Trachea of the Giraffe (Giraffa camelopardalis rothschildi)
Provedor de dados: 77
Autores: Cano,Ivana; Pérez,William.
We described the macroscopic and quantitative anatomy of the trachea of the Giraffe (Giraffa camelopardalis rothschildi). The trachea of one juvenile male giraffe (25 months of age) weighing 754 kg was used in this study. The length of the neck was 125 cm. The trachea had 107 cm in length on its cervical part and 18 cm on its thoracic part. The total number of cartilage was 87.74 at the neck and 13 at the thorax. The general shape of the duct was mostly circular. The separation of the dorsal ends of the tracheal cartilages was pronounced in the first half of the cervical trachea, reducing caudally and overlapping in the thoracic trachea. In the caudal part the trachea had a tracheal bronchus for the cranial lobe of the right lung and the end of the trachea...

Morphometric Study of the Proximal Femur Extremity in Brazilians
Provedor de dados: 77
Autores: 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...

Provedor de dados: 77
Autores: Spalding,Marianne; Rezende,Karla Mayra; Silveira,Maria Claudia Garcia; Valera,Márcia Carneiro; Leite,Horácio Faig.
Knowledge on internal dental morphology is extremely important to the correct execution of the treatment and modeling of root canals. The aim of the present study was to analyze, "in vitro", the configuration of the canal system in the mesial root of 180 maxillary first molars obtained from a Brazilian sample. The teeth diaphanized in order to confirm the presence of the MB2 canal and to determine the internal anatomy. Only in 41 % of the teeth the orifice of MB2 canal emerged from the pulp chamber floor. Among teeth two apical foramina were found in 23.3 %, a single apical foramen was observed in 15,5 % and three apical foramina were present in 2,2 %. Considering the hole sample, the MB2 canal was observed in 65.4 %, merged with the MB1 or branching from...

The anatomy and phylogeny of the African land snail Limicena Connolly, 1925 (Pulmonata: Cerastidae)
Provedor de dados: 16
Autores: Mordan, P.
An investigation of the anatomy of Limicena confirms its position as a monotypic genus in the Cerastidae. Phylogenetic analysis places Limicena as the most plesiomorphic member of a clade characterised by a pseudosigmurethrous excretory system, the more advanced members of which are Rhachistia, Amimopina and Edouardia. Its position at the base of such a widely dispersed, advanced clade with apparently xerophilic adaptations lends support to a dispersalist hypothesis for the extra-Afrotropical distribution of the Cerastidae.

The anatomy, terminology, and homology of acrorhagi and pseudoacrorhagi in sea anemones
Provedor de dados: 16
Autores: Daly, M.
The morphology of the column margin is an especially important feature in the taxonomy and biology of members of the sea anemone family Actiniidae. Despite the importance of marginal structures, their anatomy and the terminology describing them is poorly delimited. Consequently, homologies of the components of the marginal structures are poorly understood and taxonomies that depend on the presence, absence, or particular manifestation of marginal structures are confused. I review and synthesize anatomical descriptions of the marginal structures and find that they consist of two parts: a projection of the column and a holotrich-dense pad (= acrorhagus) that is histologically differentiated from the surrounding tissues. Although acrorhagi are functionally...

Characterisation of a novel fruit type found in Ehretia (Ehretiaceae, Boraginales)
Provedor de dados: 16
Autores: Gottschling, M.; Hilger, H.H.
Ehretia (Ehretiaceae, Boraginales) has been divided into two major clades, characterised by fruits with four endocarpids (Ehretia I, including species of Ehretia formerly belonging to Rotula) and by fruits with two endocarpids (Ehretia II, plus E. microphylla (= Carmona retusa) with an undivided endocarp), respectively. Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group). Its representatives are characterised by four endocarpids (as in Ehretia I), but differ in the presence of distinct lamellae on the abaxial surface of each endocarpid (as in Bourreria, also belonging to Ehretiaceae). However, molecular data suggest a close relationship with Ehretia II. At least three...

The role of wood anatomy in phylogeny reconstruction of Ericales
Provedor de dados: 16
Autores: Lens, F.; Schönenberger, J.; Baas, P.; Jansen, S.; Smets, E.
The systematic significance of wood anatomical characters within Ericales is evaluated using separate and combined parsimony analyses including 23 wood characters and 3945 informative molecular characters. Analyses of wood features alone result in poorly resolved and conflicting topologies. However, when pedomorphic character states are coded as inapplicable, the combined bootstrap topology results in an increase of resolution and support at most deeper nodes compared with the molecular analyses. This suggests that phylogenetic information from the limited number of morphological characters is not completely swamped by an overwhelming amount of molecular data. Based on the morphology of vessels and fibers, and the distribution of axial parenchyma, two...

Phylogenetic and phytogeographical relationships in Maloideae (Rosaceae) based on morphological and anatomical characters
Provedor de dados: 16
Autores: Aldasoro, J.J.; Aedo, C.; Navarro, C.
Phylogenetic relationships among 24 genera of Rosaceae subfam. Maloideae and Spiraeoideae are explored by means of a cladistic analysis; 16 morphological and anatomical characters were included in the analysis. Published suprageneric classifications and characters used in these classifications are briefly reviewed. Additionally, some new features are here reported, such as seed shape, presence or absence of endosperm, and number of cell layers in the seed coat and in the endosperm. Parsimony analyses indicate that Eriobotrya and Rhaphiolepis form a well-supported clade that is the sister to the remainder of the subfamily. This result is in agreement with published ITS sequence data. Other clades are not supported, with the exception of the group...

A study on the Gut contents of six Leathery Turtles Dermochelys Coriacea (Linnaeus) (Reptilia: Testudines: Dermochelyidae) from British waters and from the Netherlands
Provedor de dados: 16
Autores: Hartog, J.C. den; Nierop, M.M. van.
Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have...

A study was made on the Lymnaea (Galba) palustris complex in The Netherlands. Investigations on the genitalia proved that in The Netherlands two species are present, viz. L. palustris (O. F. Müller, 1774) and L. corvus (Gmelin, 1778), which can not in all cases be distinguished by shell characters. Genitalia were prepared, drawn and several measurements were carried out to investigate the variation within the two species. It appeared that most characters show a partial or total overlap. Some characters appeared to separate the two species absolutely. One of these is very useful for a quick distinction of both species, viz. the situation of the truncus receptaculi with respect to the oviductus, which character is already visible after a general dissection...

Autores: Breure, A.S.H.; Mogollón Avila, V.
The family Orthalicidae is well represented in Peru but, like in other families, some species are wellknown and others have not been reported on since their original descriptions. In this paper we present new records for well-known species and elucidate the status of several lesser known taxa. Four taxa are described as new: Bostryx chusgonensis sipas, B. fragilis, Scutalus (Scutalus) mariopenai and S. (S.) phaeocheilus altoensis. The following species are recorded as new to the Peruvian malacofauna: Corona pfeifferi, Drymaeus (D.) branneri, and Thaumastus flori. Strophocheilus tenuis Haas, 1955 is now considered synonymous with Thaumastus (Paeniscutalus) crenellus (Philippi, 1867). Plekocheilus conspicuus Pilsbry, 1932 is now placed in the synonymy of...

Autores: Migliavacca,Paulo Presti; Simone,Luiz Ricardo L.
Abstract The distinction of squid species in the genus Doryteuthis is not easy due to their morphological similarity, lack of conspicuous specific characters, and overlap geographical occurrence. This difficulty has leading to an almost exclusive molecular approach, and a premature neglect of the morpho-anatomy. To emphasize that the squid phenotypic features can be useful to identify, as well as to perform any comparative analyses (such as taxonomy and phylogeny), two close species were selected as outset. Doryteuthis pleii and D. sanpaulensis are common sympatric squids in Brazilian waters, commonly used in fisheries, not so difficult to distinguish by external features of the adult specimens. The samples were analyzed from biometric data to dissections,...

The redescription of Hiatella meridionalis (d’Orbigny, 1846) is provided as first attempt to improve the systematics of the genus in the regions of Atlantic and western Pacific. This reanalysis is based on specimens collected in the vicinity of the type localities and is based on detailed morphology of samples that some researches consider a single, wide ranging species. From the morphological characters, the more interesting are: a high quantity of papillae at incurrent siphon; the retractor muscles of siphon divided in two bundles; the small size of the palps; the muscular ring in the stomach; and the zigzag fashion of the short intestinal loops. These characters distinguish the species from the other hiatellids so far examined. Type material of the...

Abstract Helicina variabilis Wagner, 1827 (Neritimorpha, Helicinidae) is redescribed based on a sample collected in Nanuque, northern Minas Gerais, Brazil. The species description, previously based only on the shell, is expanded to the phenotypic features. The study revealed absorption of the internal shell whorls; a diaphragm muscle connected to the floor of the pallial cavity; a monoaulic pallial oviduct, with the female genital aperture inside the anal aperture, and the lack of a seminal receptacle and provaginal sac; and the pleural ganglia of the nerve ring connected with each other. The significance of these findings is discussed in the light of current taxonomic and phylogenetic knowledge.

Some characters are shared with other tellinids such as the large hemipalps compared to gills; gills with outer demibranch with a single lamella absent from the pericardial region; the type-V stomach associated with the style sac conjoined with the proximal intestine, and distal intestine presenting a dorsal and ventral group of loops, separated by the transverse muscle. The stomach presents a laterally enlarged typhlosole, although shallow, without flange in the margins. This feature is not found in other tellinid species. Another noteworthy feature in the stomach is the aperture of both caeca, which are larger than the left pouch...

Anatomical study on Myoforceps aristatus, an invasive boring bivalve in S.E. Brazilian coast (Mytilidae)
Provedor de dados: 84
Autores: Simone,Luiz Ricardo L.; Gonçalves,Eric Pedro.
The bivalve Myoforceps aristatus (Dillwyn, 1817), also known as Lithophaga aristata, have been recently collected in the coasts of Rio de Janeiro and São Paulo, Brazil; a species that bores shells of other mollusks. This occurrence has been interpreted as an invasion of this species, originally from the Caribbean. The distinguishing character of the species is the posterior extensions of the shell crossing with each other. Because specimens with this character have also been collected in the Pacific Ocean, they all have been considered a single species. However, it is possible that more than one species may be involved in such worldwide distribution. With the objective of providing full information based on Atlantic specimens, a complete anatomical...

Abstract: The objective of this work was to evaluate the physiological and anatomical traits of plants of a cacao (Theobroma cacao) clone in response to water deficit after leaf application of silicon. A randomized complete block design was used, with four replicates, in a 2x3 factorial arrangement of two water regimes (irrigated or nonirrigated) and three silicon concentrations (0.0, 1.5, and 3.0 mg mL-1) applied in wettable SiO2 powder. The plants were evaluated 20 days after the irrigation regimes were applied. The use of SiO2 increased the stability of cell membranes and the photochemical efficiency of the plants under water deficit. The 1.5 mg mL-1 concentration of SiO2 increased photosynthetic rate, water use efficiency, and carboxylation efficiency,...

Provedor de dados: 88
Autores: Tarré,Erika; Magioli,Claudia; Margis-Pinheiro,Márcia; Sachetto-Martins,Gilberto; Mansur,Elisabeth; Santiago-Fernandes,Lygia D. R.
Somatic embryogenesis was induced from cotyledon explants of eggplant cultured on MS medium supplemented with 54 µM NAA. Anatomical analysis of somatic embryo initiation and development was performed during the first four weeks. Proembryo formation was observed after the second day of culture, directly from perivascular cells or via pro-embryogenic masses derived from indeterminate meristematic masses (IMMs) originated in the vascular tissue. Those IMMs also gave rise to root primordia after 10 days of culture. The origin of embryos is discussed as well as the similarities between somatic embryogenesis and adventitious root formation.

(In vitro culture at low temperature and ex vitro acclimatization of Vriesea inflata an ornamental bromeliad). In vitro culture by seeds is a technique for preservation of threatened species because it may provide a large number of plants with genetic diversity. The bromeliad Vriesea inflata (Wawra) Wawra, an ornamental bromeliad, is extensively and illegally collected from the nature and must be preserved. It is possible to form plant threatened collections in vitro by reducing the temperature of culture, while occupying little space, with the consequent reduction of maintenance costs. This work evaluated the influence of temperature on in vitro growth and morphology of plants of V. inflata, with the aim of establishing a slow growth-rate and analyzing...

Anatomy, ultrastructure and secretion of Hibiscus pernambucensis Arruda (Malvaceae) extrafloral nectary
Provedor de dados: 88
Autores: Rocha,Joecildo Francisco; Machado,Silvia Rodrigues.
This paper reports on the extrafloral nectary (EFN) of Hibiscus pernambucensis, a native shrub species occurring in mangrove and restinga along Brazil's coastline. EFNs occur as furrows with a protuberant border on the abaxial surface veins of the leaf blade. Each nectary consists of numerous secretory multicellular trichomes, epidermal cells in palisade-like arrangements and non-vascularized parenchyma tissue. Nectar secretion is prolonged, since secretion starts in very young leaves and remains up to completely expanded leaves. Reduced sugars, lipids, and proteins were histochemically detected in all the nectary cells; phenolic substances were detected in the vacuoles of the epidermal palisade cells and in some secretory trichome cells. The secretory...

This paper describes the anatomy of the floral scape for 12 species of Bromeliaceae, belonging to the subfamilies Bromelioideae, Tillandsioideae and Pitcairnioideae. Although all the scapes have a similar organization, there are variations in the structure of the epidermis, cortex and vascular cylinder. Such variations are described for the studied scapes and, when considered together they can help to identify the species. These aspects are described for each scape and discussed under a taxonomic point of view.

Development, structure and distribution of colleters in Mandevilla illustris and M. velutina (Apocynaceae)
Provedor de dados: 88
Autores: APPEZZATO-DA-GLÓRIA,BEATRIZ; ESTELITA,MARIA EMÍLIA MARANHÃO.
Colleters of Mandevilla illustris and M. velutina are present on the cotyledons, shoot apices, mature leaves and on the nodal region, where they are interpetiolar and intrapetiolar. In M. velutina there are two colleters on the adaxial basal part of the leaf blade, and in M. illustris, this number varies. The differentiation of the colleters occurs in the early stages of leaf development. When colleters are mature, they consist of a long head on a short stalk. The central core of the colleter is made up of parenchymatous cells that may exhibit phenolic compounds and is surrounded by radially elongated epithelial cells. The foliar and intrapetiolar colleters can exhibit vascularization. The colleters produce a translucient sticky substance that reacts...

Abstract  In Brazil, the main cultivated passion fruit species is Passiflora edulis, which is affected by Fusarium soil fungus. P. mucronata species stands out because it presents resistance to this fungus, being thus an alternative rootstock to yellow passion fruit. Therefore, the aim of this study was to evaluate the anatomy of mini-grafting by top cleft grafting and simple English type grafting, using shoot tips of adult P. edulis plants in clonal rootstocks of P. mucronata. When the rootstocks reached approximately 2.5 mm in diameter and 20 cm in height, grafting was carried out with Parafilm® tape fasteners and silicone clip. At the end of 60 days, histological analysis of the grafting region was performed to verify the formation of the scarring...

Provedor de dados: 103
Autores: Piffer,Pedro Ribeiro; Arruda,Eliane Pintor de; Passos,Flávio Dias.
Macoma biota Arruda &amp;amp; Domaneschi, 2005, is a recently described species known only from the intertidal zone of Praia da Cidade, Caraguatatuba Bay, in the state of São Paulo, southeastern Brazil. The main purpose of the present paper is to describe the biology of M. biota, beginning with a detailed analysis of its anatomy and functional morphology and how these attributes are correlated with its habitat and life history. The morphology of the organs in the pallial cavity and their sorting devices indicate that this species has efficient mechanisms to process large amounts of particles that enter this cavity via the inhalant current. M. biota can rapidly select the material suitable for ingestion and direct the undesired excess to the rejection...

Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
Provedor de dados: 103
Autores: Pizá,Julia; Cazzaniga,Néstor J.; Ghezzi,Natalia S.
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry &amp; Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or lamellae in its shell aperture - was however transferred to Odontostomus by Pilsbry in 1902 on the basis of its building forward of the aperture-margins. It is currently placed in its own monotypic subgenus, Cyclodontina (Ventania) Parodiz, 1940, on the basis of about the same argument. In this paper we redescribe its shell morphology and, for the first time, describe the internal anatomy of the...

Water deficit in relation to leaf and stem anatomy of Eucalyptus camaldulensis Dehn. shoots cultivated in vitro
Provedor de dados: 63
Autores: Souza,Gustavo Maia; Gonçalves,Antonio Natal; Almeida,Marcílio de.
Shoots of E. camaldulensis seedlings from three distinct provenances were submitted to three different levels of in vitro water deficit induced by the addition of sorbitol in the growth media. Transversal sections from the leaf blades and stems were anatomically analysed using the historesin inclusion technique. Shoots from the different provenances presented distinct responses to the treatments. The Gilbert River provenance was the most sensible. The basic alterations found on the anatomical structure in response to the water deficit were: cell collapse, late tissue differentiation, vascular bundle and epidermis disorganization, and alterations on the mesophyll and epidermis thickness.

Autores: Garcia,José Francisco; Grisoto,Eliane; Botelho,Paulo Sérgio Machado; Parra,José Roberto Postali; Appezzato-da-Glória,Beatriz.
The sugarcane spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is a pest of mechanically-harvested sugarcane in Brazil, when trash burning is not performed. To better understand the differences in feeding behavior of adults and nymphs of this pest and the subsequent disorders that arise, stylet penetration through fixation, staining and sectioning was investigated. Nymphs cause a "physiological disorder" damaging the tracheary system of the roots, slowing or preventing water and nutrient flow, with phloem and xylem dehydration. Nymphs insert their stylets through the epidermis, crossing the cortex, endodermis and pericycle before reaching the vascular cylinder, where they feed in the sieve-tube elements of the primary phloem. In contrast,...

ABSTRACT We describe the anatomical structure of roots originating from the apocole of Attalea microcarpa compared to the primary root, by means of usual methods for optical microscopy. The adventitious roots are differentiated in the apocole associated to vascular bundles, and can remain as a single structure or branch. They have the basic root structure characteristic of Arecoideae palms, without schizogenous spaces, which are observed in the primary root, in addition to few air spaces. Mucilages, starch and proteins were present in both types of roots. Adventitious roots of the apocole are described for the first time in Arecaceae.

ABSTRACT Charcoal is widely accepted as evidence of the occurrence of palaeo-wildfire. Although fossil charcoal remains have been used in many studies, investigation into the anatomical changes occurring during charring are few. The present study analyses changes in selected anatomical characters during artificial charring of modern wood of three species of the genus Araucaria (i.e. Araucaria angustifolia, Araucaria bidwillii and Araucaria columnaris). Wood samples of the studied species was charred under controlled conditions at varying temperatures. Measurements of anatomical features of uncharred wood and artificial charcoal were statistically analysed. The anatomical changes were statistically correlated with charring temperatures and most of the...

Autores: Carvalho,Jordano Dorval Tavares de; Oliveira,João Marcelo Santos de; Freitas,Cesar Carvalho de; Martins,Meriélem Saldanha.
ABSTRACT This study presents a morphoanatomical analysis of Dyckia ibicuiensis , D. polyclada and D. racinae stamens. Flowers at anthesis were desiccated and their stamens were processed using common light microscopic techniques. Morphologically, the androecium in these species is differentiated by the disposition of the stamens around the gynoecium and by general anther characteristics. Included stamens, with antesepalous filaments different from those of the antepetalous, anthers in a radial disposition, always curved, and sporangia facing the gynoecium characterize D. ibicuiensis and D. racinae . This configuration results from the filament connation, as well as special anatomical characteristics of the anthers, such as the connective with thickenings....

Anatomical and ultrastructural aspects of leaf galls in Ficus microcarpa L.f. (Moraceae) induced by Gynaikothrips ficorum Marchal (Thysanoptera)
Provedor de dados: 39
Autores: Souza,Silvana Cristina P. M. de; Kraus,Jane Elizabeth; Isaias,Rosy Mary S.
Several species of Ficus present leaf galls and the goal of this research is to study the structural alterations involved in the formation of leaf galls caused by Gynaikothrips ficorum on F. microcarpa, an ornamental plant. The galls of young and mature leaves were separated into two developmental stages based on the presence of lesions on leaf lamina and the degree of leaf folding. Swellings of the lamina were observed in young and mature leaves during gall development which coincided with the areas of cellular hypertrophy and tissue hyperplasia. Swellings were detected in a greater amount and more precociously on young leaves when compared to mature ones. In young leaves, the cecidogenetic responses were quicker and led to further structural differences...

Comparative thallus anatomy of two Parmotrema (Parmeliaceae, lichenized Ascomycetes) with reticulate maculae
Provedor de dados: 39
Autores: Barbosa,Suzana Bissacot; Marcelli,Marcelo Pinto.
Using conventional techniques for structural studies under conventional microscopy, polarizing light microscopy and scanning electron microscopy this work describes and compares the thallus anatomy of two Parmotrema species with reticulate maculae, previously included in the genus Rimelia: Parmotrema cetratum (Ach.) Hale and P. clavuliferum (Räsänen) Streimann. The data showed that the species are anatomically similar, including the presence of epicortex, the upper cortex anatomy and the characteristics of rhizines and ciliae. In the medulla of the two species there are star-shaped clusters of hyphae associated with the presence of salazinic acid. This study showed that the anatomical characteristics are constant for the Parmotrema group studied.

Floral glands in asclepiads: structure, diversity and evolution
Provedor de dados: 39
Autores: Demarco,Diego.
ABSTRACT Species of Apocynaceae stand out among angiosperms in having very complex flowers, especially those of asclepiads, which belong to the most derived subfamily (Asclepiadoideae). These flowers are known to represent the highest degree of floral synorganization of the eudicots, and are comparable only to orchids. This morphological complexity may also be understood by observing their glands. Asclepiads have several protective and nuptial secretory structures. Their highly specific and specialized pollination systems are associated with the great diversity of glands found in their flowers. This review gathers data regarding all types of floral glands described for asclepiads and adds three new types (glandular trichome, secretory idioblast and...

Fruit ontogenesis in Clusia parviflora Humb. &amp;amp; Bonpl. ex Willd. (Clusiaceae)
Provedor de dados: 39
Autores: Mourão,Káthia Socorro Mathias; Marzinek,Juliana.
Aspects of the morpho-anatomy of developing fruits and seeds of Clusia parviflora are presented and discussed as a continuation of the study of these organs in Clusiaceae. The fruit is a septifrage capsule; the suberized exocarp is derived from the external epidermis of the ovary. The mesocarp originates from the ovarian mesophyll and remains parenchymal in nature. The endocarp is derived from the internal epidermis of the ovary and the endocarp is derived from the inner ovary epidermis as well as from three to four adjacent subepidermal layers, with tangentially elongated cells which become lignified and contribute to fruit dehiscence. The ovules are anatropous, bitegmic, with an endothelium, and give rise to equally anatropous seeds. The exotesta has...

Testa structure in Erythrina speciosa (Leguminosae): the role of the mucilaginous stratum in the acquisition of physical dormancy
Provedor de dados: 39
Autores: Magalhães,Camila Ribeiro; Oliveira,Denise Maria Trombert.
ABSTRACT Seeds of Erythrina speciosa (Papilionoideae) exhibit physical dormancy, but evidence has suggested that the proportion of impermeable seeds increases with storage. There are no records of structural variation in the testa of E. speciosa that justifies the difference in the percentage of seeds with physical dormancy. Therefore, the present study investigated the difference in permeability between mature seeds of E. speciosa that were freshly collected and those stored for 12 months. Seeds were examined for changes in testa structure that could result in differences in the percentage of seeds in physical dormancy. Thus, imbibition curves and water gaps were determined, and surface micromorphology, anatomy, and histochemistry of the testa were...

Small and hard seeds: a practical and inexpensive method to improve embedding techniques for light microscopy
Provedor de dados: 39
Autores: Ribeiro,Rafaella Cardoso; Oliveira,Denise Maria Trombert.
The traditional techniques employed for embedding plant samples are not suitable for the proper processing of small seeds with hard seed coats. Usually, these seeds are broken off from blocks during microtomy, which limits the technical success of this procedure. In this study, Melastomataceae seeds of 101 species were treated prior to embedding in historesin according to three treatments: (1) control, using the standard procedure; (2) fixation and subsequent softening with Franklin solution, glycerin and heating in a water bath; and (3) softening with Franklin solution and subsequent fixation (glycerin and heating in a water bath were also included). For Melastomataceae species, the second treatment provides the best results, and we were able to produce...

Abstract Chronic stress exposure commonly increases adrenals weight and changes their morphology. This study aimed to compare four methods to delimitate the cortical and medullary layers of adrenals glands in Nelore bulls. Fresh adrenals did not present differentiation between layers. Then, frozen adrenals were distributed in plastics bags with fixative Bouin (G1), 96ºGL ethylic alcohol (G2), 10% formaldehyde (G3), or 2.5% glutaraldehyde (G4). After 12 hours of fixation, the G1 adrenal glands did not show the entire cortical layer marked by Bouin’s solution. For G2 and G3 there was a poor contrast, while for G4 there was a reasonable contrast. After 24 hours of fixation, G1 had an excellent contrast between layers, while G2 and G4 had a reasonable contrast...

Autores: MARTINS,SHIRLEY; ALVES,MARCCUS; SCATENA,VERA L.
ABSTRACT Cyperaceae is an angiosperm family with the greatest diversity of species with Kranz anatomy. Four different types of Kranz anatomy (chlorocyperoid, eleocharoid, fimbristyloid and rhynchosporoid) have been described for this angiosperm family, and the occurrence and structural characteristics of these types are important to trace evolutionary hypotheses. The purpose of this study was to examine the available data on Cyperaceae Kranz anatomy, emphasizing taxonomy, geographic distribution, habitat and anatomy, to infer the potential origin of the Kranz anatomy in this family. The results showed that the four types of Kranz anatomy (associated with C4 photosynthesis) in Cyperaceae emerged numerous times in unrelated phylogenetic groups. However, the...

The present study aimed to describe histological characteristics of the female genital tract ofSotalia guianensis, in order to assist in future studies on the reproductive biology of these animals. Females of different ages, from stranding events on beaches in northeastern Brazil, were used. Fragments of all organs were collected and processed for light and scanning electron microscopy. Histological analyses showed that these structures were similar to those found in terrestrial mammals, with some peculiarities, such as the presence of...

Autores: PINTO,MARINA P.E.; BRANCO,ÉRIKA; FIORETTO,EMERSON T.; PEREIRA,LUIZA C.; LIMA,ANA R.
Saguinus niger popularly known as Sauim, is a Brazilian North primate. Sympathetic chain investigation would support traumatic and/or cancer diagnosis which are little described in wild animals. The aim of this study was to describe the morphology and distribution of sympathetic chain in order to supply knowledge for neurocomparative research. Three female young animals that came death by natural causes were investigated. Animals were fixed in formaldehyde 10% and dissected along the sympathetic chain in neck, thorax and abdomen. Cranial cervical ganglion was located at the level of carotid bifurcation, related to carotid internal artery. In neck basis the vagosympathetic trunk divides into the sympathetic trunk and the parasympathetic vagal nerve....

Autores: Lima,Ana R.; Fioretto,emerson T.; Fontes,Rodrigo F.; Imbeloni,Aline A.; Muniz,José A. P. C.; Branco,Érrika.
Saimiri sciureus is a New World non-human primate (NHP) that inhabits Brazilian rain forests. Surgical interventions in wild NHPs can be considered common both for experimental studies procedures and corrective procedures for endangered species. Among various anesthetic procedures, the epidural anesthesia or blockades, depending on the surgical procedure, might be considered elective for wild monkeys, mostly based on its safeness, efficiency and non-time consuming characteristics. However its safeness would be limiting because of the spinal cord arrangement. Notwithstanding the available former studies on New World NHP anatomy, the description of the medullar cone of Saimiri sciureus is still scarce. Therefore, we believe that the better understanding the...

Provedor de dados: 42
Autores: MEDINA,MARIA CAMILA; HOYOS-GÓMEZ,SAÚL E.; DEMARCO,DIEGO; TUBERQUIA,DINO.
ABSTRACT Wild plant species with potential for use as ornamental green foliage are often reported. Nevertheless, there are few studies evaluating morphological and anatomical aspects associated with this use. Preliminary trials suggest that the species of Sphaeradenia (Sander ex Mast.) Harling, a Cyclantaceae that occurs from Costa Rica to Peru, is suitable to be used as fresh foliage because of attractiveness of their leaves in vase and its durability without showing tissue damage, compared with other genera of this family. Through the study of anatomical characters, it is possible to predict the potential of a species that can serve as ornamental foliage. In this study, three foliar anatomical features (thickness of the cuticle and leaf, and percentage...

Morpho-anatomical features of underground systems in six Asteraceae species from the Brazilian Cerrado
Provedor de dados: 42
Autores: Appezzato-da-Glória,Beatriz; Cury,Graziela.
In the Brazilian Cerrado (neotropical savanna), the development of bud-bearing underground systems as adaptive structures to fire and dry periods can comprise an important source of buds for this ecosystem, as already demonstrated in the Brazilian Campos grasslands and North American prairies. Asteraceae species from both woody and herbaceous strata have subterranean organs that accumulate carbohydrates, reinforcing the adaptive strategy of these plants to different environmental conditions. This study aims to analyse the morpho-anatomy of underground systems of six species of Asteraceae (Mikania cordifolia L.f. Willd., Mikania sessilifolia DC, Trixis nobilis (Vell.) Katinas, Pterocaulon alopecuroides (Lam.) DC., Vernonia elegans Gardner and Vernonia...

Simplified three-dimensional model provides anatomical insights in lizards' caudal autotomy as printed illustration
Provedor de dados: 42
Autores: AMORIM,JOANA D.C.G. DE; TRAVNIK,ISADORA; SOUSA,BERNADETE M. DE.
Lizards' caudal autotomy is a complex and vastly employed antipredator mechanism, with thorough anatomic adaptations involved. Due to its diminished size and intricate structures, vertebral anatomy is hard to be clearly conveyed to students and researchers of other areas. Three-dimensional models are prodigious tools in unveiling anatomical nuances. Some of the techniques used to create them can produce irregular and complicated forms, which despite being very accurate, lack didactical uniformity and simplicity. Since both are considered fundamental characteristics for comprehension, a simplified model could be the key to improve learning. The model here presented depicts the caudal osteology of Tropidurus itambere, and was designed to be concise, in order...

Morphological and histochemical characterization of the digestive tract of the puffer fish Sphoeroides testudineus (Linnaeus 1758) (Tetraodontiformes: Tetraodontidae)
Provedor de dados: 42
Autores: FAGUNDES,KAINÃ R.C.; ROTUNDO,MATHEUS M.; MARI,RENATA B.
ABSTRACT Morphological analysis of the digestive tract of Sphoeroides testudineus showed an esophagus with an anterior and a posterior portion, the abdominal pouch. No stomach was observed between the abdominal pouch and the intestine. The intestine was arranged in three segments and two loops, and the distal portion had the rectum opening into the anus. Histochemical analyses showed that the esophagus secreted acid mucosecretions, and that there was a qualitative increase in goblet cells from the proximal to distal area of the intestine. The rectum showed cells secreting acid and neutral mucus. Given these features, this species presents a morphology which creates a link between its ecology and behavior.

Autores: Martins,Aline Redondo; Pütz,Norbert; Novembre,Ana Dionisia da Luz Coelho; Piedade,Sônia Maria de Stefano; Glória,Beatriz Appezzato da.
Brazilians have been using the underground organs of Smilax species in alternative medicine since the 19th century because of their anti-rheumatic qualities. However, even nowadays, these species are explored only by extractivism. Studies on seed germination and development of these organs could be useful to preserve these plants. After germination, seedling development of Smilax polyantha was analyzed to understand underground stem formation. Furthermore, to analyze the ontogenesis of the underground system, seedlings aged from one to twelve months were sectioned. One of the most striking features of this species is the presence of two stem branching systems. The plumule gives rise to the first stem branching system with negative geotropism. Its first...

Bauhinia forficata link shoot regeneration: histological analysis of organogenesis pathway
Provedor de dados: 52
Autores: Mello,Marcia O.; Melo,Murilo; Appezzato-da-Glória,Beatriz.
Plant regeneration was achieved from cells of callus induced from hypocotyl segments of Bauhinia forficata on half strength Murashige and Skoog culture medium supplemented with several concentrations of BAP. Within 40 days of culture shoot buds formation was observed on callus surface. Calli were then transferred to a same composition culture medium without plant growth regulator in order to induce shoot elongation. Histological studies indicated that in vitro plant regeneration in B. forficata occurred through indirect organogenesis. Meristemoids consisting of small cells with dense cytoplasm and prominent nuclei were randomly distributed throughout the callus surface indicating early stages of shoot bud differentiation.

Autores: Fernando,Juliana A.; Melo,Murilo; Soares,Marli K. M.; Appezzato-da-Glória,Beatriz.
Mature zygotic embryos of Carica papaya L. ‘Sunrise Solo’ were used as explants for embryogenesis induction. The explants were inoculated on Murashige and Skoog culture medium supplemented with 2 mg.L-1 2,4-dichlorophenoxyacetic acid and incubated in darkness at 25+2°C. Histological analysis of callogenesis and somatic embryogenesis indicated occurrence of direct and indirect somatic embryogenesis development. Direct somatic embryo formation was observed from hypocotyledonary epidermic cells only from explant 18 days after inoculation. Somatic embryos formed indirectly were originated from embryogenic superficial cells of pre-embryonic complexes located on peripherical and on internal cell layers of callus 49 days after inoculation. Diverse morphological...

Autores: Souza,Luiz Antonio de; Iwazaki,Maisa C.; Moscheta,Ismar S.
The morphology and anatomy of the fruit and seed of Tabebuia chrysotricha (Mart. ex DC.) Standl. (Bignoniaceae), a species typical of the Atlantic rainforest, is presented and discussed. The fruit was a loculicidal capsule, dehiscing through two slits, liberating a seminiferous column. The dehiscence process of the fruit involved separation tissue and two crossed sclerenchymatous mesocarpic layers (middle and subepidermic). The seed originated from an anatropous, unitegmic and tenuinucellate ovule. It was exotestal and presented polyembriony. The endothelium and endosperm were conserved in the mature seed and protected the embryo. Adventive embryos were made up of hypostase cells.

Histological analysis of the callogenesis and organogenesis from root segments of Curcuma zedoaria Roscoe
Provedor de dados: 52
Autores: Mello,Marcia O.; Melo,Murilo; Appezzato-da-Glória,Beatriz.
Callus was induced from root segments taken from in vitro grown plants of Curcuma zedoaria Roscoe. The explants were cultured on agar-solidified Murashige and Skoog medium supplemented with 13.4muM of alpha-naphthaleneacetic acid and 2.2muM of 6-benzylaminopurine at 25ºC in the dark. Histological analysis revealed that callus was formed from the hypertrophied cortical parenchyma cells of the explant. Some of these cells underwent division while the surrounding cells accumulated starch. Callus was capable of shoot bud regeneration after 70 days when it was transfered to liquid medium of the same composition. After 30 days in liquid medium, buds developed from nodular structures. The adventitious shoots developed extensive root systems when they were placed...

Provedor de dados: 52
Autores: Carmello-Guerreiro,Sandra Maria; Paoli,Adelita A. Sartori.
The fruit of Schinus terebinthifolius Raddi is a globose red drupe with friable exocarp when ripe and composed of two lignified layers: the epidermis and hypodermis. The mesocarp is parenchymatous with large secretory ducts associated with vascular bundles. In the mesocarp two regions are observed: an outer region composed of only parenchymatous cells and an inner region, bounded by one or more layers of druse-like crystals of calcium oxalate, composed of parenchymatous cells, secretory ducts and vascular bundles. The mesocarp detaches itself from the exocarp due to degeneration of the cellular layers in contact with the hypodermis. The lignified endocarp is composed of four layers: the outermost layer of polyhedral cells with prismatic crystals of calcium...
