This study deals with total phenolic content, antiproliferative and proapoptotic activity of methanolic extracts from different Teucrium species and the effect on the prooxidant/antioxidant status in HCT-116 cells. The total phenolic content of the extracts was measured spectrophotometricaly and the obtained results ranged from 56.62 mg/g to 172.50 mg GA/g. The antiproliferative activity of met...

Among the numerous chemicals discharged into the surrounding environment, bisphenol A (BPA) and octylphenol (OP) have been shown to increase oxidative stress in body by disturbing the prooxidant/antioxidant balance of cells. Cinnamon aqueous extract (CAE) is a natural product rich in polyphenolic compounds that have antioxidant activity. This study was designed to investigate the protective eff...

We have read with interest the work by Lesgards et al. (1) on the effect of different lifestyle factors on their test system, which measures the resistance of red blood cells to an oxidative challenge. Their study showed that psychologic stress is a major factor influencing antioxidant status. This finding encouraged us to share our experiences of a earlier study that resulted in similar conclu...

Pregnancy in insulin-dependent diabetes mellitus is associated with a greater incidence of fetal abnormality. Animal studies suggested that increased free-radical production and antioxidant depletion may contribute to this risk. The objective of this work was to evaluate oxidative stress and antioxidant capacity in hypertensive, diabetics, and healthy control women during labor. Simultaneous de...

the aim of present study was to investigate whether food restriction combined with exercise training could attenuate the oxidative stress and promote angiogenesis in a rat model of heart failure. 50 male wistar rats weighing 250-300 g were randomly divided into 5 groups including: 1) sham; they were fed ad libitum food, n=10. 2) heart failure group; 3) exercise group; they run on a treadmill 5 ...

Platonin (4,4'-dimethyl-3,3'-di-n-heptyl-8-[2-(4methyl-3-n-heptylthiazole)] -2,2'-dicarbocyanine diiodine) is one of the photosensitive trithiazolepentamethine cyanine dyes. Visible light (VL)-promoted photodegradation products of platonin in an aqueous environment were identified as 3-heptyl4-methylthiazoline-2 -carbaldehyde (1), tetradecane-7-thiol (2), 1-nonene (3), heptylamine (4), 3-heptyl...

ilex spinigera (aquifoliaceae) plant is an evergreen tree or shrub with thick glossy dark green leaves and red fruits. this plant has medicinal properties and has been used traditionally in northern iran for malaria treatment. the aim of this work is to evaluate the antioxidative activities and the inhibitory effect of i.spinigera on the oxidation of dna. we have found no reports about the popu...

background and objectives: otostegia persica (burm.) boiss. is an endemic plant of iran with various applications in traditional medicine which contains of several antioxidant constituents. this research was aimed to investigate the effect of hydroalcoholic extract from o. persica aerial parts in human umbilical vein endothelial cells (huvecs) using hydrogen peroxide (h2o2) as an inducer of oxi...
