SUMMARY: Barrett's esophagus is a condition where the distal third of the esophagus changes its epithelial lining from non- keratinized stratified squamous to simple columnar. This cross-sectional descriptive study was conducted to characterize the esophageal mucosa in the third trimester of pregnancy an...
Squamous metaplasia of the rete ovarii is an ovarian pathologic change characterized by replacement of the normal single layered cuboidal epithelium of the rete ovarii by a stratified squamous keratinized epithelium. Uterus and ovaries from a local slaughterhouse pregnant crossbreed cow were evaluated th...
ABSTRACT Acute retinal pigment epitheliitis (ARPE) is an idiopathic, self-limiting inflammatory retinal disorder that particularly affects healthy young individuals. The characteristic fundoscopic appearance of the acute retinal pigment epitheliitis includes a fine pigment stippling surrounded by a yello...
ABSTRAT Background: The presence of intestinal metaplasia in the distal esophagus (Barrett's esophagus) is an important precursor of adenocarcinoma. Knowledge of the risk factors and the process by which the Barrett develops is very important and Helicobacter pylori (HP) can contribute to this developm...

ABSTRACT Background: Tissue diagnosis is required for gastric subepithelial lesions for differential diagnosis of GISTs. However, there has not been consensus about the best needle for EUS-guided sampling of these lesions. Aim: To evaluate the diagnostic yield of EUS-FNA for gastric subepithelial les...
ABSTRACT Purpose: To develop a rabbit experimental study to test the hypothesis that surgical repair of hypospadias with severe ventral curvatures might be completed in one stage, if a graft, such as buccal mucosa, could be placed over the tunica vaginalis flap used in corporoplasty for ventral lengthen...

Epidermoid and dermoid cysts are hamartomas localized on the neck, head, or trunk, usually visible at birth. In some instances, careful medical examination may help to find most epidermoid and dermoid cysts. Ambiguity about their exact pathogenesis exists and dysontogenetic, traumatic, and thyroglossal a...
Os cistos são lesões formadas por uma cavidade revestida de tecido epitelial, as quais contêm, em seu interior, material líquido ou semisólido, podendo ser classificados em cistos odontogênicos e não odontogênicos. Apesar de existirem diversas modalidades de tratamentos descritas na literatura pa...
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 gu...

Este trabalho teve por objetivos o estudo do comportamento do tecido epitelial e a formaçäo de um novo sulco gengival após procedimento de RTG em defeitos de furca classe II criados cirurgicamente, em cäes. A análise histológica foi realizada em plano vestíbulo-lingual e foi possível, também, de...
