| ABSTRACT The purpose of this study was to examine the ovaries and the oviduct of juvenile females of the broad-snouted caiman, Caiman latirostris (Daudin, 1802), using light microscopy, histochemical and immunocytochemical techniques. The ovarian cortex was observed to contain groups of germinative cells and abundant previtellogenic follicles at different stages of development. In previtellogenic follicles, the oocyte was surrounded by a single cuboidal layer of granulosa cells, supported by the theca layer. The theca was formed by a concentric layer containing collage nous fibers, predominantly type I, and several smooth muscle fibers. The inner perivitelline layer appeared as a narrow basophilic region between the oocyte and the granulosa. The ovarian... |

| 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... |

| The brachioradialis is an important muscle that acts in the external rotation of the forearm (supination). However, its occurrence is controversial and little studied in the order Carnivora. Thus, this study investigates the occurrence and anatomo-functional arrangement of this muscle in wild carnivorans species. Fifty-eight thoracic limbs of specimens from species of Canidae, Procyonidae, Mustelidae and Felidae were dissected. Measurements of the length of the muscle (ML), the length of the forearm (FL), latero-medial width of the muscle (MW) and the lateral-medial diameter of the forearm (FD) were obtained to establish the ratios MW/FD and ML/FL in order to investigate the relative proportion of the muscle in relation to the forearm of each species. The... |

| El objetivo del estudio fue describir las características anatómicas y establecer hipótesis morfo-funcionales del esqueleto del miembro torácico de Mazama gouazoubira. Para ello, se utilizaron los miembros torácicos de cuatro adultos jóvenes. Los huesos se prepararon mediante ebullición y fueron blanqueados en una solución de peróxido de hidrógeno para obtener descripciones comparativas, mediciones osteométricas y radiografías digitales. En comparación con los rumiantes domésticos, la escápula resultó ser ancha y plana, con el acromion pequeño, el proceso coracoides muy pequeño y sin tuberosidad de la espina. El húmero se observó alargado con la diáfisis redondeada en una sección transversal y con proyecciones no articulares lisas. La ulna se unió al radio... |
