Background: Strenuous acute exercise induces oxidative stress in the active muscles and circulation, However, consumption of products rich in antioxidants may potentially ameliorate these effects. Objective: The present investigation was conducted to determine the effect of Artichoke (Cynara scolymus L.) extract on oxidative stress and antioxidant defense after aerobic exercise in young athle...

conclusions the results suggest that physical activity improves metabolic parameters, which interfere in the development of fatty liver and has a protective role against the development of nafld. results statistical analysis demonstrated that the training group had significant changes in weight, bmi, tc, tg, ldl, vldl, hdl/ldl, tc/ hdl, ast and alt, whereas there was no significant change in hd...

azotobacter vinelandii, a gamma-proteobacterium, is an obligate aerobic free-living gram-negative soil bacterium capable of fixing nitrogen. oxygen transfer rate into the cell is reduced by the increase of alginate concentrations during the course of a. vinelandii cultivation. this phenomenon provides a low intracellular oxygen concentration needed for nitrogenase activity. the aim of this stud...

Aerobic glycolysis is defined as glucose utilization in excess of that used for oxidative phosphorylation despite sufficient oxygen to completely metabolize glucose to carbon dioxide and water. Aerobic glycolysis is present in the normal human brain at rest and increases locally during increased neuronal activity; yet its many biological functions have received scant attention because of a prev...

OBJECTIVE To investigate whether birth weight acts as a biological determinant of later aerobic fitness, and whether fat-free mass may mediate this association. METHODS The European Youth Heart Study (EYHS) is a population-based cohort of two age groups (9 and 15 years) from Denmark, Portugal, Estonia and Norway. Children with parentally reported birth weight >1.5 kg were included (n = 2 749)...

Heterocyclic N-oxides are an interesting class of antitumor agents that selectively kill the hypoxic cells found in solid tumors. The hypoxia-selective activity of the lead compound in this class, tirapazamine, stems from its ability to undergo intracellular one-electron reduction to an oxygen-sensitive drug radical intermediate. In the presence of molecular oxygen, the radical intermediate is ...

there are many reasons for decrease of the functional activity of the brain like aging of the neurons, bacterial diseases and neuro inflammations. nowadays, the effects of exercise on physical and mental health have been proven but its effects on motor functions as well as neuro inflammation is an issue that has recently been studding. neuro inflammation is a mechanism that can be caused by bac...

OBJECTIVE To issue a recommendation on the types and amounts of physical activity needed to improve and maintain health in older adults. PARTICIPANTS A panel of scientists with expertise in public health, behavioral science, epidemiology, exercise science, medicine, and gerontology. EVIDENCE The expert panel reviewed existing consensus statements and relevant evidence from primary research ...
