Introduction: Oxidative stress is an important factor in the induction of diabetes complications especially peripheral neuropathy and hyperalgesia, and it has been proven that regular aerobic exercise and vitamin E have antioxidant effects. Therefore, this study was designed to examine effects of regular aerobic exercise and vitamin E on thermal pain threshold in streptozocin-induced diabeti...

This paper describes experimental research to directly quantify the ordinary heterotrophic organism (OHO) cell yield coefficient under anoxic and aerobic conditions with real wastewater as substrate. Until recently these two values were assumed equal in activated sludge models, despite theoretical predictions that the anoxic yield should be reduced relative to its aerobic value. In this study, ...

Cholecystitis and cholelithiasis are frequently met surgical conditions in North India. The presence of bacteria in bile at the time of surgery or invasive diagnostic procedures predisposes to complications like septicaemia. Aim of this study was to study the bacteriological profile – aerobic & anaerobic in the bile of patients undergoing cholecystectomy. The present study included 50 patients ...

OBJECTIVES/HYPOTHESIS Biofilms occur in animal models of acute otitis media (AOM) and in children with recurrent AOM (rAOM) and chronic otitis media with effusion (OME). We therefore studied the ability of nontypeable Haemophilus influenzae (NTHi) strains from children to form biofilms in vitro under conditions we presumed occurred in the middle ear during AOM, rAOM, and OME. STUDY DESIGN Eva...

THE aerobic decomposition of plant materials has in recent years attracted much attention, on account of its importance in the formation of synthetic manure, in the decomposition of soil organic matter, in the purification of sewage and trade wastes, in the decay of wood etc., but comparatively little is known regarding the course and rate of decomposition under anaerobic an,d partially aerobic...

We have previously demonstrated that the presence of oxygen is necessary for the production of toxic shock syndrome toxin 1 (TSST-1) by Staphylococcus aureus in vitro. To investigate the mechanism by which oxygen might regulate toxin production, we identified homologs in S. aureus of the Bacillus subtilis resDE genes. The two-component regulatory system encoded by resDE, ResD-ResE, has been imp...

PURPOSE Evaluation of metabolic parameters and cardiac function is important to determine the decrease in aerobic exercise capacity under hypoxic conditions. However, the variations in metabolic parameters and cardiac function and the reasons for the decrease in aerobic exercise capacity under hypoxic conditions have not been clearly explained. The purpose of this study was to compare the respo...

Monitoring studies show that urban surface streams in the United States are commonly contaminated with pesticides, and contamination by organophosphates and carbamates is of particular concern because of their aquatic toxicity. The degradation and sorption of four common organophosphate and carbamate insecticides were studied in urban creek sediments from southern California, USA. In sediment, ...
