Although increased superoxide dismutase (SOD) activity is often associated with enhanced resistance of cells and organisms to oxidant challenges, few direct tests of the antioxidant importance of this enzyme have been carried out. To assess the importance of SOD in defending against gamma-radiation, we employed Escherichia coli with deficient, normal, and super-normal enzyme activities. Surpris...
Background: scopolamine induced neuroinflammation limits its long-term clinical use. Several agents/strategies were attempted to prevent neuroinflammatory but not found suitable for use.
 Objective: To investigate the neuroprotective activity of chrysin nanoparticle on neuroinflammation.
 Material and Method: Male Albino wistarrats (180- 230 grms) evenly divided into 5 groups. Group I...
BACKGROUND Reduced arterial compliance is associated with an increased rate of morbidity and mortality in cardiovascular disease. Exercise is beneficial for compromised arterial compliance. However, the beneficial effects of exercise are lost with exhaustion. Lycium barbarum L. has been used in China for centuries to maintain good health. In this regard, the primary purpose of this study was to...
•2 Excessive production and/or inadequate removal of reactive oxygen species, especially superoxide anion (O ), have been implicated 2 in the pathogenesis of many cardiovascular diseases, including atherosclerosis, hypertension, diabetes, and in endothelial dysfunction by •2 decreasing nitric oxide (NO) bioactivity. Since the vascular levels of O are regulated by the superoxide dismutase (SOD) ...
The non-enzymatic reaction between glucose and protein can be chemically reversed by transglycation. Here we report the transglycation activity of hydralazine using a newly developed MALDI-TOF-MS based assay. Hydralazine mediated transglycation of HbA1c, plasma proteins and kidney proteins was demonstrated in streptozotocin (STZ) induced diabetic mice, as evidenced by decrease in protein glycat...
Alzheimer's disease (AD) pathogenesis involves an imbalance between free radical formation and destruction. In order to obtain a novel preclinical anti-AD drug candidate, we synthesized a series of novel hydroxyl chalcone analogs which possessed anti-free radical activity, and screened their effects on scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) and OH free radicals in vitro. Compound C7, ...
The modern living lifestyle is known to produce various physical and psychological stresses and subject the individual to produce oxidative stresses as well. The aim of this study has been to assess the effect of yogic breathing exercises (pranayama) on the oxidatives stress. The study group consisted of 30 young male volunteers, trained for the purpose of this study and an equal number of cont...
Triphala, an Indian ayurvedic triherbal formulation, is an equiproportional mixture of fruits of three herbs, amalaki (Emblica officinalis), haritaki (Terminalia chebula) and bibhitaki (Terminalia bellerica). The present study focused on phytocompounds detection and comparative analysis of various biochemical activities in the aqueous and methanolic extracts of triphala and its constituting her...
Background & Objective: Diabetes is a metabolic disorder caused by low secretion or resistant to the insulin action. Oxidative stress, an imbalance between the free radical production and antioxidant defense systems of the body, is strongly related to diabetes and its symptoms. The aim of the present study is to evaluate effect of regular swimming on antioxidant system in diabetes. Materia...
