Oxidative stress is commonly induced when plants are grown under drought stress conditions.To analyze how salicylic acid (SA) can partly alleviate drought-induced oxidative stress and negative impacts of drought on physiology and growth of Salvia nemorosa plants, we investigated the physiological responses of S. nemorosa to SA application under drought stress. The treatments were composed of Co...
background: glycowithanolides (withaferin a), is one of the main withanolides active principle isolated from plant withania somnifera and is claimed that it possess the aphrodisiac, sedative, rejuvenate and life prolonging properties. objective: in the present investigation, antioxidant activity of active principles of withania somnifera was tested against d-galactose induced oxidative stress i...
Background and Aims: Metabolic syndrome, a common metabolic disorder, for the serious health consequences such as insulin resistance and lipid abnormalities has been considered as a major clinical challenge with obscure causes. Oxidative stress is an important component of metabolic syndrome, contributing in its development. Troxerutin, a semi-synthetic derivative of natural bioflavonoid rutin,...
The metabolic syndrome (MS) recognized as a major cause of type 2 diabetes and cardiovascular diseases, has become one of the major public health challenges worldwide. The pathogenesis of the metabolic syndrome is multiple and still poorly understood. No single factor has yet been identified as an underlying causal factor. There is a growing belief, however, that obesity, specially visceral obe...
background: excess reactive oxygen species (ros) in the semen is believed to affect fertility in men. morphologically abnormal sperms and their relation to seminal oxidative stress in infertile and subfertile men are not clear. objective: to correlate various sperm morphological defects with seminal oxidative stress in infertile and subfertile men. materials and methods: the study included 25 p...
The cell has an intricate quality control system to protect its mitochondria from oxidative stress. This surveillance system is multi-tiered and comprises molecules that are present inside the mitochondria, in the cytosol, and in other organelles like the nucleus and endoplasmic reticulum. These molecules cross talk with each other and protect the mitochondria from oxidative stress. Oxidative s...
Background: The risk of atherosclerosis and cancer is high in hemodialysis (HD) patients. There is evidence that HD causes oxidative stress. However, the causative factors of oxidative stress are unknown. It has been suggested that HD imposes an additional oxidative stress on patients with chronic renal failure by activation of granulocytes on dialyzer membranes resulting in an imbalance betwee...
objective: surgery is considered the primary treatment for male infertility from clinical varicocele. one of the main events associated with varicocele is excessive production of reactive oxygen species (ros). n-acetyl-l-cysteine (nac), an antioxidant that scavenges free radicals, is considered a supplement to alleviate glutathione (gsh) depletion during oxidative stress. despite beneficial eff...
cirrhosis is associated with hyperdynamic circulation, manifesting as increased cardiac output and decreased systemic vascular resistance. the aim of this study was to investigate the effect of cirrhosis on heart apoptosis and involvement of nitric oxide (no) and oxidative stress in the possible altered apoptosis of cirrhotic hearts. twenty-eight days after bile duct ligation, heart tissues wer...
