Moderate physical training attenuates the effects of perinatal undernutrition on the morphometry of the splenic lymphoid follicles in endotoxemic adult rats.

Background/aims: Physical training is a well-known inducer of positive physiological adaptations. The effects of moderate physical training on the morphometry of splenic lymphoid follicles of endotoxemic rats submitted to a perinatal low-protein (LP) diet were evaluated.

Methods: Male Wistar rats were divided into two groups according to their mother's diet (17% casein, control, C) and, undernourished (8% casein, LP diet).

[Pulmonary hypertension associated with acquired immunodeficiency syndrome: presentation of five cases and review of the literature].

Several cardiorespiratory diseases may complicate the acquired immunodeficiency syndrome. Pulmonary hypertension is a rare clinical disorder with a poor prognosis. We describe this syndrome in five patients seen at our service who presented infection with the acquired immunodeficiency virus, and we review the literature.

Sugarcane biopolymer patch in femoral artery angioplasty on dogs.

Purpose: The objective of this study was to evaluate the use of the sugarcane biopolymer membrane in femoral artery patch angioplasty on dogs.

Methods: Eight dogs were submitted to bilateral femoral artery patch angioplasty with a sugarcane biopolymer membrane patch on one side and e-PTFE patch on the contralateral side. This research was performed at Experimental Surgical Research Laboratory of the Centro de Ciências da Saúde at Universidade Federal de Pernambuco.
