Serum activities of oxidative burst enzymes in HIV infected subjects

Abnormal serum pancreatic enzymes in an HIV infected child.

Activities of oxidative enzymes in mycoplasmas.

The activities of several oxidoreductases were measured in three fermentative and two nonfermentative Mycoplasma species that were grown under aerobic or anaerobic conditions. Acholeplasma laidlawii MG, Mycoplasma hyorhinis GDL, and Mycoplasma pneumoniae FH had very high apparent activities of pyruvate dehydrogenase and pyruvate dehydrogenase complex compared with the activities of mammalian fi...

The effect of 12 weeks combined training on the antioxidant/oxidative indexes in HIV-infected patients

Background: Human immunodeficiency virus (HIV) infection have been associated with high oxidative stress in HIV patients. The aim of this study was to investigate the effect of 12 weeks combined training on the antioxidant/oxidative indexes in HIV-infected patients. Materials and methods: In this semi-experimental study, 30 AIDS patients were selected in a targeted and accessible way and...

Gastrointestinal immune responses in HIV infected subjects.

The gut associated lymphoid tissue is responsible for specific responses to intestinal antigens. During HIV infection, mucosal immune deficiency may account for the gastrointestinal infections. In this review we describe the humoral and cellular mucosal immune responses in normal and HIV-infected subjects.

Apoptosis and oxidative burst in neutrophils infected with Mycobacterium spp.

Two of the better characterized antimicrobial mechanisms displayed by human neutrophils are the reactive oxygen species (ROS) production and the induction of apoptosis. Their importance in mycobacterial infections is, however, controversial and we aimed to analyze them simultaneously in neutrophils infected with either Mycobacterium tuberculosis or the non-pathogenic M. gordonae. Neither specie...
