The aim of this study was to evaluate the expression of IMP3, an independent poor prognostic factor for many cancers, and its association with clinicopathological features and HER2 status. Gastrectomy specimens from 106 patients were evaluated by immunohistochemistry and fluorescence in situ hybridization. HER2 overexpression was found in 4.71 % of the(More)
Intrapulmonary vasodilation is a hallmark of the hepatopulmonary syndrome (HPS). However, its effects on respiratory mechanical properties and lung morphology are unknown. To determine these effects, 28 rats were randomly divided to control and experimental HPS groups (eHPS). The spontaneous breathing pattern, gas exchange, respiratory system mechanical(More)
Dermatoscopy of melanocytic lesions has guided the decision of when or not to biopsy a lesion. The use of this tool has increased clinical examination's sensitivity and specificity in 89% and 96% respectively. However, dermatoscopic evaluation of amelanotic or hypomelanotic melanomas, as well as metastases, can be difficult. There is still no(More)
Epidermolytic ichthyosis is a rare autosomal dominant disease that manifests at birth with fragile blisters and erosions that evolve into hyperkeratotic lesions associated or not with erythroderma. When the disease is associated with a mutation in cytokeratin 1, it may be related to hyperkeratosis of palms and soles, but this is not usually found when(More)
PURPOSE To study the influence of glutamine on functional and morphological changes of liver in the extrahepatic biliary obstruction through an experimental model in rats. METHODS Seventy Wistar rats were divided into four groups: control (group C) fictitious operation, (group FO), submitted to laparotomy with handling of bile ducts, but without hepatic(More)
PURPOSE To evaluate histopathologic alterations of the peritoneum exposed to heat shock. METHODS Sixty rats were randomly distributed into 6 groups: Heat Shock (HS), High Temperature (HT), Body Temperature (BT), Temperature 0oC (TZ), Sham (SH) and Control (CG) with 10 animals each. The peritoneal cavity of animals from groups HS, HT, BT and TZ was(More)
Syringocystadenoma papilliferum is a rare benign adnexal tumor that frequently shows apocrine differentiation. It usually develops on the scalp and is associated with a nevus sebaceus in 40% of cases. Although the clinical presentation may differ, its histology is characteristic. Reports have been made of dermoscopy used in cases of adnexal tumors such as(More)
The efficiency of terbinafine was tested in C57BL/6 mice inoculated with the Leishmania (Leishmania) amazonensis strain MHOM/BR/PH8. The mice were administered: terbinafine at a dose of 100mg/kg/d by via oral; 0.9% saline solution orally as the control; and subcutaneous sodium stibogluconate 400mg SbV/kg/d as gold standard, for 20 days. Terbinafine was(More)
OBJECTIVE To correlate chronic liver disease diagnosed by transcutaneous liver biopsy guided by ultrasound, with ultrasound findings with B-mode and Doppler of the right hepatic vein; 2) to compare the wave patterns between the study group and the control group; 3) to compare the right hepatic vein Doppler findings with histopathology findings as a possible(More)
