Background: Studies indicate that obestatin, an anti-hunger peptide, plays an important role in energy balance, GH secretion, and body weight. It has been physiologically shown that obestatin apposes the function of Ghrelin. The purpose of the present study was to investigate the effects of a single session of aerobic exercise in trained women (a 1.5-mile run) on the expression of obestatin gen...
Oxygen is considered one of the main factors affecting probiotic bacteria survival due to the induction of oxidative damages caused by the action of reactive oxygen species (ROS). It has been shown that oxidative stress resistance in lactic acid bacteria is strongly dependent on the type of cell metabolism. Shift from fermentative to respiratory metabolism (through the addition of heme and mena...
Studies have identified two distinct biological processes capable of biotransforming polychlorinated biphenyls (PCBs): aerobic oxidative processes and anaerobic reductive processes. It is now known that these two complementary activities are occurring naturally in the environment. Anaerobic PCB dechlorination, responsible for the conversion of highly chlorinated PCBs to lightly chlorinated orth...
Introduction and purpose: Cardiac response to body core temperature variation measured with the very low-frequency parameter of heart rate variability. The aim of this study was to investigate the variability of very low frequency due to different temperatures of aerobic training in water and dry. Materials and methods: 40 academic active male were selected as research subjects. Then, all subje...
A promoting effect of large bowel contents on colonic carcinogenesis as seen in the animal model is still incompletely explored in man. We investigated simultaneously deoxycholate absorption (as marker of colonic mucosal exposure to tumour promoting bile salt metabolites), mouth-anus transit time, and the ratio of anaerobic to aerobic bacteria in stool in 10 persons with colonic adenomas and in...
Mitomycin C and its methylated analogue porfiromycin (Por) have significant potential as adjuncts to regimens presently used for treating solid tumors because of their preferential toxicity to cells existing in an hypoxic environment. An understanding of the factors producing the differential activity of these drugs under aerobic and hypoxic conditions would facilitate the development of new ag...
In this research, the effects of different color intensities, anoxic + anaerobic times and types of substrate on color removal effectiveness were studied using 16-litre bench scale sequencing batch reactor (SBR) anoxic + anaerobic/aerobic models. The systems were fed with a synthetic wastewater containing 500 mg/l of COD, 50 mg/l of N, 15 mg/l of P along with 10, 40 and 80 mg/l of reactive diaz...
AbstractThe Aitamir Formation is divided into two members the lower sandstone and the upper shale. 32 genera and 57 species of foraminifera have been recognized. According to identified foraminifera Rotalipora appenninica Interval Zone, Rotalipora globotruncanoides (Rotalipora brotzeni) interval zone and Whiteinella aumalensis-Dicarinella canaliculata assemblage zone are proposed and a l Albian...
Abstract Background: Water and electrolyte balance are critical for the maintenance of general health. Exercise creates much variation in renal homodynamic and electrolytes excretion. Sauna is also an extreme hot environment placing an individual in heat stress. The aim of this study was to compare the effects of one session aerobic activity and sauna on serum and urinary sodium and potass...
