To explore how screening for potential nutrient bio-activity could be improved by integrating biological and chemical markers of cellular responses, we assessed the effect of the known anti-oxidants, catechin and chlorogenic acid, on anti-oxidant activity in vitro. We determined an active concentration (25 μM) of each compound and then measured its effects on anti-oxidant gene expression and re...
OBJECTIVE/AIM A new group of autoantibodies in Rheumatoid Arthritis (RA), the anti-cyclic citrullinated peptide (anti-CCP) antibodies directed to citrulline-containing proteins, which are of value for the severity of RA. Up to date, the relationship between anti-CCP antibodies and oxidant, anti-oxidant activity in patients with RA has not been elucidated in the previous studies. In this study w...
BACKGROUND Oxidative stress is recognized to be one of predisposing factor in the pathogenesis of COPD. The oxidant/antioxidant imbalance is significantly pronounced in patients with COPD exacerbation. N-acetylcysteine (NAC) seems to be able to reduce COPD exacerbations by modulating the oxidative stress in addition to its well-known mucolytic activity, but there are discordant findings on the ...
The anti-oxidant activities for a diverse set of flavonoids as TEAC (Trolox equivalent anti-oxidant capacity), assay were subjected to 3D-QSAR (3 dimensional quantitative structural-activity relationship) studies using CoMFA (comparative molecular field analysis) and CoMSIA (comparative molecular similarity indices analysis). The obtained results indicated superiority of CoMSIA model over CoMFA...
Xanthine oxidase is a key enzyme responsible for hyperuricemia, a pre-disposing factor for Gout and oxidative stress-related diseases. Only two clinically approved xanthine oxidase inhibitors Allopurinol and Febuxostat are currently used for treatment of hyperuricemia. However, owing to their side effects there is a need for new non-purine-based selective inhibitors of xanthine oxidase. In the ...
Schiff bases are a class of organic compounds which have good chelating properties. Due to this, they can form complexes with metal ions the transition series. and their derivatives bioactive hence find widespread uses in various fields inorganic, medicinal chemistry. These synthesised by condensation reactions been studied extensively as exhibit biological properties like anti-oxidant, anti-fu...
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...
52 Exogenous oocyte secreted factors such as bone morphogenetic protein 15 (BMP15), together 53 with hormones traditionally used during in vitro oocyte maturation, increase the developmental 54 competence of cumulus oocyte complexes (COCs). Separately, FSH and BMP15 induce 55 different metabolic profiles within COCs, namely FSH increases glycolysis while BMP15 56 stimulates FAD and NAD(P)H auto...
This article discusses some of the mechanisms through which alcohol, delivered pre- or postnatally, alters the activity of the rodent hypothalamic-pituitary-adrenal (HPA) axis. We show that blockade of prostaglandin synthesis, but not opiate receptors, modestly interfered with the HPA axis to acute alcohol injection. Pretreatment with a low dose of alcohol (0.3 g/kg) did not significantly modif...
