the antioxidant properties of ruta graveolens l. were evaluated by two different methods; free radical scavenging using dpph and inhibition of lipid peroxidation by the ferric thiocyanate method. the ic50 value of the methanol extract in dpph inhibition was 200.5 μg/ml which was acceptable in comparison with bht (41.8 μg/ml). in thiocyanate method, the plant extract demonstrated activity as muc...

background & aim: considering that antioxidants are known as effective free radicals scavenger, it may be able to improve the in vitro oocyte maturation and the fetal quality. this study was designed to determine the effect of gundelia tournefortii leaves (gte) hydro-alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: germinal vasicle (gv) were recovere...

background & aim: oocytes in vitro maturation is an enormously promising technology for the treatment of infertility, yet its clinical application remains limited owing to poor success rates. therefore this study was designed to determine the effect of gundelia tournefortii root hydro alcoholic extract as a source of antioxidant on in vitro oocyte maturation. experimental: in this study, th...

background & aim: marigold or calendula officinalis l. is a annual herb belongs to the asteraceae family.  marigold is a valuable medicinal plant which is used in pharmaceutical industry.  in addition, this plant is cultivated as an ornamental plant. aim of current study was to evaluate the effect of different concentrations of jasmonic acid (ja), and salicylic acid (sa) on phytochemical pr...

BACKGROUND Growth Regulation by Estrogen in Breast cancer (GREB1) was an estrogen receptor (ER) target gene, and GREB1 expression inversely correlated with HER2 status, possibly as a surrogate marker for ER status and a predictor for tamoxifen resistance in breast cancer patients. In the present study, we examine the function and regulation of GREB1 in breast cancer, with the goal to develop GR...

nloaded variable rate of missed cancer in endoscopic biopsies and lack of other biomarkers reduce the effectivef surveillance programs in esophageal cancer. Based on the “field cancerization” hypothesis that tumors ithin a transformed field with an altered biochemical phenotype, we sought to test if metabolic profiling differentiate between histologically normal tissue from individuals with and...
