aim: we conducted this study to investigate the role of ramadan fasting on oxidative stress. materials and method: 23 people (16 male, 7 female) aged between 25 and 65 years were recruited in this study. 10cc venous blood samples were taken after 8- to 10- hours fasting on 2 different times: a week before ramadan and at the end of ramadan (day 27). portions of the serum samples were used immedi...

background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...

objective(s) comparison of prooxidant-antioxidant balance (pab) assay with crocin assay. materials and methods twenty eight serum samples were chosen, pab and the total antioxidant capacity were measured by pab assay and crocin, respectively, and the correlation of both assays, along with their correlation with other clinical and biochemical parameters, were determined. results a significant ne...

objectives: we have investigated the effect of a saffron supplement, given at a dose of 100 mg/kg, on prooxidant-antioxidant balance (pab) in individuals with metabolic syndrome. materials and methods: a randomized, placebo-controlled trial design was used in 75 subjects with metabolic syndrome who were randomly allocated to one of two study groups: (1) the case group received 100mg/kg saffron ...

results a significant higher serum pab value was observed in shift working and daytime nurses (152.28 ± 43.64 hk) in comparison to the control group (63.64 ± 34.41 hk index), p value = 0.001. in day time nurses, also serum pab between male (119.09 ± 47.14 hk) and female (162.53 ± 37.02 hk) in nursing workers was significant, p value = 0.005. in the night shift working nurses, there was also a s...

The chronic disorder of arterial circulation in the lower extremities due to the atherosclerotic injuries of the femoral-popliteal-tibial arteries was accompanied by the shift of the blood prooxidant-antioxidant balance towards more active free radical oxidation and by a depletion of antioxidant system. After restoring arterial blood flow in the ischemic lower extremities this balance was shift...

Preterm infants are vulnerable to the oxidative stress due to the production of large amounts of free radicals, antioxidant system insufficiency, and immature oligodendroglial cells. Reactive oxygen species (ROS) play a pivotal role in the development of periventricular leukomalacia. The three most common ROS are superoxide (O2(•-)), hydroxyl radical (OH(•)), and hydrogen peroxide (H2O2). Under...

background : gliomas are the most common primary brain tumors of the central nervous system. among a number of different bio-molecular events, molecular connections between oxidative stress pathways and their development is prevalent. oxidative stress is the consequence of an imbalance between pro-oxidant factors and antioxidant defense. this imbalance may lead to dna damage and changes in grow...
