background: cyclosporine a (csa) is a potent immunosuppressant drug with therapeutic and toxic actions. the use of csa is limited by its toxicity. several researchers had proposed that oxidative stress could play an important role in csa-induced toxicity. arbutin has recently been shown to possess antioxidative and free radical scavenging abilities.the present study was designed to investigate ...
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...
Oxidant stress influences many cellular processes, including cell growth, differentiation, and cell death. A well-recognized link between these processes and oxidant stress is via alterations in Ca(2+) signaling. However, precisely how oxidants influence Ca(2+) signaling remains unclear. Oxidant stress led to a phenotypic shift in Ca(2+) mobilization from an oscillatory to a sustained elevated ...
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...
introduction: the molecular mechanisms involved in pathogenesis of esophageal cancer have been the main concern of several studies. in this study, we aimed to investigate the changes of serum prooxidant-antioxidant balance (pab) value as a redox index, as well as serum c-reactive protein (crp) compared to healthy control group. materials and methods: in a cross-sectional study, blood samples we...
introduction drought stress reduces plant growth by affecting various physiological and biochemical processes, such as photosynthesis, respiration, translocation, ion uptake, carbohydrates, nutrient metabolism and growth promoters. garlic (allium sativum l.) is an annual bulb crop that has been cultivated since ancient times and was used as a spice and condiment for many centuries. garlic is an...
Asthma is a chronic inflammatory disease of the respiratory tract of unknown aetiology. In severe asthma airway diathesis is profound, and thus apparent. Recently, however, evidence has indicated that specific inflammatory abnormalities exist even in the airways of subjects with mild disease. As inflammation is often associated with an increased generation of reactive oxygen species (ROS), and ...
