AIM Exercise effects in subjects with HIV/AIDS are not entirely understood. The study aimed to investigate the effects of a supervised exercise program on the physical fitness and immunological function of HIV-infected subjects. METHODS Twenty-seven highly active antiretroviral therapy treated HIV-infected patients (age: 45±2 years; CD4-T: 21.3±2.2%) were(More)
This study investigated the role of opioid receptor (OR) subtypes as a mechanism by which endurance exercise promotes cardioprotection against myocardial ischemia-reperfusion (IR) injury. Wistar rats were randomly divided into one of seven experimental groups: 1) control; 2) exercise-trained; 3) exercise-trained plus a non-selective OR antagonist; 4)(More)
BACKGROUND We evaluated structural microvascular alterations in the skeletal muscle and left ventricle, as well as endothelium-dependent microvascular reactivity in the skeletal muscle, of diabetic rats subjected to long-term aerobic exercise training. METHODS Diabetes was experimentally induced by a combination of a high-fat diet with a single low dose(More)
BACKGROUND there is a lack of research about the relationship between exercise and the psychological well-being of HIV-infected (Human Immunodeficiency Virus) patients. OBJECTIVE the objective of this study was to investigate the influence of a physical training program on life satisfaction and on the immunological function in HIV-patients. METHODS a(More)
BACKGROUND Acute myocardial infarction is the leading cause of morbidity and mortality worldwide. Furthermore, research has shown that exercise, in addition to reducing cardiovascular risk factors, can also protect the heart against injury due to ischemia and reperfusion through a direct effect on the myocardium. However, the specific mechanism involved in(More)
UNLABELLED The autonomic modulation in HIV patients undergoing highly active antiretroviral therapy (HAART) was investigated. The heart rate variability (HRV) was assessed in 13 HIV patients (43±2 years) and 10 healthy controls (31±5 years) at rest, during exercise, and recovery. All time (standard deviation of NN intervals, SDNN; root mean of squared sum(More)
The present work proposes the development of a bio-battery composed by an ultrathin monolithic structure of an electrospun cellulose acetate membrane, over which was deposited metallic thin film electrodes by thermal evaporation on both surfaces. The electrochemical characterization of the bio-batteries was performed under simulated body fluids like sweat(More)
Osteosarcoma is the most common primary bone tumor in children and adolescents, with a 5-year disease free survival rate of 70%. Current chemotherapy regimens comprise a group of chemotherapeutic agents in which doxorubicin is included. However, tumor resistance to anthracyclines and cardiotoxicity are limiting factors for its usage. Liposomal formulations(More)
BACKGROUND Aerobic interval exercise training has greater benefits on cardiovascular function as compared with aerobic continuous exercise training. OBJECTIVE The present study aimed at analyzing the effects of both exercise modalities on acute and subacute hemodynamic responses of healthy rats. METHODS Thirty male rats were randomly assigned into three(More)
The therapeutic potential of early exercise training following cerebral hypoperfusion was investigated on brain perfusion and inflammation in rats with permanent bilateral occlusion of the common carotid arteries (2VO). Wistar rats were subjected to 2VO or sham surgery and each group was then subdivided randomly into sedentary or exercise groups. Early(More)
