     Clinical and Epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. These beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. Therefore screening for antioxidant properties of plant extracts has been one of the inte...

Objectives: The present study evaluates the antioxidant and cytotoxic activity of different extract (methanol, chloroform, petroleum ether) of Zanthoxylum alatum. Methodology: The antioxidant activities of all the three above mentioned extracts of Zanthoxylum alatum were measured by different in vitro standard methods like 1,1-diphenyl-2-picrylhydrazil radical (DPPH), superoxide anions, nitric ...

BACKGROUND Several plants traditionally used in treatment of a variety of infections in South Africa are reported in ethnobotanical surveys. Many of these plants including Ziziphus mucronata subsp. mucronata lack scientific reports to support their medicinal importance. METHODS The antioxidant activities and phenolic contents of the acetone, ethanol and aqueous extracts of the stems of Z. muc...

Water stress is one of the most important abiotic limiting factors that restricts growth, development and productivity of horticulrural crops. In vitro methods have been successfully used for evaluating water deficit stress in plants. In this regards, responses of four Iranian grapevine genotypes to drought stress induced by polyethylene glycol 6000 at -5, -5.24, -5.65, -6.24 and -7 bar were...

Although organophosphate (OP)-induced acetylcholinesterase (AChE) inhibition is the critical mechanism causing toxicities that follow exposure, other biochemical events, including oxidative stress, have been reported to contribute to OP toxicity. Fullerenes are carbon spheres with antioxidant activity. Thus, we hypothesized that fullerenes could counteract the effects of OP compounds and tested...

Epithelial Ovarian Cancer (EOC) "cholinic phenotype", characterized by increased intracellular phosphocholine content sustained by over-expression/activity of choline kinase-alpha (ChoKα/CHKA), is a metabolic cellular reprogramming involved in chemoresistance with still unknown mechanisms.By stable CHKA silencing and global metabolic profiling here we demonstrate that CHKA knockdown hampers gro...

OBJECTIVE Ionizing radiation produces free radicals which induce DNA damage and cell death. Origanum vulgare leaf extract (OVLE) is a natural compound and its capability of scavenging free radicals and its antioxidant activity have been demonstrated by many researchers. In this study, using micronucleus assay, radioprotective effect of OVLE against clastogenic and cytotoxic effect of gamma irra...
