In this work, proteins in extracellular polymeric substances extracted from anaerobic, anoxic and aerobic sludges of wastewater treatment plant (WWTP) were analyzed to probe their origins and functions. Extracellular proteins in WWTP sludges were identified using shotgun proteomics, and 130, 108 and 114 proteins in anaerobic, anoxic and aerobic samples were classified, respectively. Most protei...

Background. Non-alcoholic fatty liver disease, is the most common reason of liver disorders that can be controlled by dieting and regular physical activity.  Objectives. The aim of this study was to investigate the effect of aerobic continuous training on serum levels of myonectin, insulin resistance and liver enzymes in rats with non-alcoholic fatty liver disease. Methods. Thirty-four male W...

Objective: Dysmenorrhea is common and disturbs the quality of life of women. Therefore, the aim of this study was to evaluate the effect of ginger supplement on aerobic training capacity and dysmenorrhea in overweight girls. Materials and Methods: In this semi-experimental study, 52 overweight female students of Shahid Chamran university of Ahwaz were randomly divided into two groups. The supp...

Associations among baseline physical activity, aerobic fitness, changes in physical activity, and 7-y changes in adiposity were determined. The sample consisted of 602 males and 644 females, aged 20-69 y, from the 1981 Canada Fitness Survey and the 1988 Campbell's Survey. Questionnaire-derived measures of physical activity level consisted of activity energy expenditure (AEE) and time spent on p...

Conversion of glycogen to hexose monophosphate in muscle appears to be limited by the activity of phosphorylase (l-3). The enzyme exists in two forms, a and b. Increased phosphorylase activity can result from (a) conversion of phosphorylase b to a (l-5), and (6) regulation of phosphorylase b activity by changes in the intracellular levels of adenine nucleotides (6). In the isolated rat heart pe...

Objective. To compare longitudinally PAC of asthmatic children against that of healthy controls during ten months. Methods. Twenty-eight asthmatic children aged 7-15 years and 27 matched controls each performed six submaximal exercise tests on treadmill, which included a test of EIA (exercise-induced asthma). Predicted aerobic capacity (mLO(2)/min/kg) was calculated. Spirometry and development ...

BACKGROUND Ageing is associated with a declining physical activity level (PAL) and changes in the diurnal activity pattern. Changes in the activity pattern might help explaining the age-associated reduction of physical activity. OBJECTIVE The aims were to investigate diurnal activity patterns within groups of older adults classified by PAL, to investigate diurnal activity patterns within age-...
