Mild-intensity Exercise Triggers VEGF in the Digestive Tract Via Both Hypoxic and Nonhypoxic Mechanisms

Abstract Hypoxia occurs in the splanchnic region during exercise associated with sympathetic activity. In the elderly, vascular insufficiency and low vascular endothelial growth factor (VEGF) expression are observed. Compared to young people, sympathetic signals of older individuals are blunted and more ...

Efeitos da vareniclina no tecido pulmonar em modelo animal

J. bras. pneumol; 46 (2), 2020
RESUMO Objetivo O objetivo deste estudo foi investigar os efeitos agudos e crônicos da vareniclina no tecido pulmonar em um estudo experimental. Métodos Um total de 34 ratos foi alocado aleatoriamente em grupos de estudo (vareniclina) e controle. Assim, os ratos foram divididos em dois grupos: (i) gr...

Correlation between nutritional assessment and oxidative stress in candidates for liver transplant

ABSTRACT Objective To evaluate the oxidative profile, nutritional status and food intake (caloric value; macronutrients; vitamins A, E and C; and zinc), and to correlate oxidative stress with nutritional status in patients who were candidates for liver transplant. Methods This is a cross-sectional, a...

Effects of intra-dentate gyrus microinjection of myokine irisin on long-term potentiation in male rats

Arq. neuropsiquiatr; 77 (12), 2019
ABSTRACT Induction of long-term potentiation (LTP) increases the storage capacity of synapses in the hippocampal dentate gyrus (DG). Irisin is a myokine generated from FNDC5 (a gene precursor) during exercise. Although intra-cornu ammonis 1 administration of irisin fortifies LTP in mice with Alzheimer's ...

Rubeosis faciei diabeticorum is not associated with oxidative stress and skin autofluorescence

An. bras. dermatol; 94 (5), 2019
Abstract Background Rubeosis faciei diabeticorum is a persistent facial erythema in patients with diabetes mellitus. The actual pathogenesis has not been studied. However, it is speculated to be a cutaneous diabetic microangiopathy. Objective Examine the correlation between the severity of facial eryth...

Effects of Chronic Exposure to Mercury on Angiotensin-Converting Enzyme Activity and Oxidative Stress in Normotensive and Hypertensive Rats

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Mercury's deleterious effects are associated with increased cardiovascular risk. Objective: To determine whether chronic exposure to inorganic mercury increases the activity of angiotensin-converting enzyme and its relationship with oxidative stress in several organs and tissues. ...

Protective effect of extract of the Camellia japonica L. on cerebral ischemia-reperfusion injury in rats

Arq. neuropsiquiatr; 77 (1), 2019
ABSTRACT Objective: We investigated the protective effect of the extract of the Camellia japonica L. flower on cerebral ischemia-reperfusion injury in rats. Methods: The rat ischemia-reperfusion injury was induced by middle cerebral artery occlusion for 90 minutes and reperfusion for 48 hours. The anim...

Therapeutic effect of adenosine on experimentally induced acute ulcerative colitis model in rats

Acta cir. bras; 34 (12), 2019
Abstract Purpose To examine the therapeutic effect of external adenosine on an acetic acid-induced acute ulcerative colitis model in rats. Methods Thirty male mature rats were divided into three groups as control, acute colitis (AC) and AC+adenosine group (AC+AD). AC was induced by rectal administrat...

Analysis of BMSCs-intervened viscoelasticity of sciatic nerve in rats with chronic alcoholic intoxication

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To investigate the impact of bone mesenchymal stem cells (BMSCs) intervention on the viscoelasticity of sciatic nerve in rats with chronic alcohol intoxication (CAI). Methods: The CAI rat models were prepared, divided into model groups, and treated with either BMSCs or basic fibrobla...
