Being widely used since its discovery, tobacco contains many chemical substances including nitric oxide, hydrocarbons, aldehydes, phenols, quinone and semiquinone radicals, causes the formation of oxygen-induced free radicals directly or indirectly. Therefore, it is important to know oxidant/antioxidant properties, phenolic content Nicotiana rustica Linn., effect studies on Paraoxonase (PON 1) ...
Introduction & Objective: Infertility affects 10-15% of couples worldwide, and male factors account for nearly half of all infertility cases. Evidence suggests that genetic variation in anti-oxidant enzymes could influence male infertility. Glutathione peroxidase 1 (GPx1) is an anti-oxidant selenoenzyme that detoxify peroxide radicals. GPx1 Pro198Leu polymorphism causes an aminoacid change from...
Abstract Background and Objective: Flavonoids play an important role in non-enzymatic reaction against oxidative stress. These are polyphenolic compounds in tea structure that could be reacted with free radicals and neutralized them. In this study, we investigated the anti-oxidant impact of Camellia Sinesis on the liver of thioacetamide -injected male albino mice. Material and Methods...
The methanolic extracts were analyzed for anti-neoplastic enzymes screening, while antioxidant capabilities investigated fifteen isolates. also have enhanced radical scavenging ability against the stable ABTS (2,2’azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (86.34 ± 0.007 mM TE/g extract), nitric oxide (64.79 0.004 μg/ml), phosphomolybdenum (1.69 0.024 mg AAE/g FRAP (ferric reducing of pl...
Akt, a protein kinase hyperactivated in many tumors, plays a major role in both cell survival and resistance to tumor therapy. A recent study,1 along with other evidences, shows interestingly, that Akt is not a single-function kinase, but may facilitate rather than inhibit cell death under certain conditions. This hitherto undetected function of Akt is accomplished by its ability to increase re...
Background Due to a lack of antioxidant enzymes in plasma, plasma proteins are preferential targets of oxidant injury. Reaction of chlorinated oxidants (e.g. hypochlorous acid), generated from activated neutrophils, with plasma albumin gives rise to formation of an oxidized protein fraction, termed advanced oxidation protein products (AOPPs). AOPPalbumin is a potent high-density lipoprotein (HD...
Anti-oxidant effects of propofol (2, 6-diisopropylphenol) were evaluated agains carbon tetrachloridet CCl4 -induced oxidative stress in rat liver. 30 male rats were equally divided in to 6 groups (5 rats each). Group I (control), while Group II was given CCl4 (3 mL /Kg/day, IP). Animals of Groups III received only propofol (10 mg/Kg/day, IP). Group IV was given propofol+ CCl4. Group V was admin...
