OBJECTIVE Echium amoenum Fisch. & C.A. Mey. is used for the treatment of various diseases in traditional medicine. This plant is a major source of anthocyanins with beneficial cardiovascular properties such as anti-atherosclerotic and antihypertensive effects. In the present study, the protective and antioxidant effects of anthocyanin-rich E. amoenum extract were evaluated on human vascular end...

This study relates to a method for evaluating the degradation efficiency of Ascaris lumbricoides eggs through a Fenton reaction, using hydrogen peroxide (H2O2) at 100, 250, and 500 mg/L, ferrous sulfate (FeSO4) at 458 mg/L Fe(2+) and pH values of 3, 4.5, and 6. The experiments were conducted according to a 3(2) experimental design, with 1:1, 3:1, and 5:1 (H2O2/Fe(2+)) molar ratios. The oxidatio...

The degree of redundancy between thrombopoietin (Tpo) and steel factor (SF) cytokine pathways in the regulation of hematopoiesis was investigated by generating mice lacking both c-Mpl and fully functional c-Kit receptors. Double-mutant c-Mpl(-/-)Kit(Wv/Wv) mice exhibited reduced viability, making up only 2% of the offspring from c-Mpl(-/-)Kit(Wv/)(+) intercrosses. The thrombocytopenia and megak...

BACKGROUND Pinus eldarica is a widely growing pine in Iran consisting of biologically active constituents with antioxidant properties. This study investigates the effect of hydroalcoholic extract of P. eldarica bark against oxidative damage induced by hydrogen peroxide (H2O2) in human umbilical vein endothelial cells (HUVECs). METHODS The total phenolic content of P. eldarica extract was dete...

This research was focused on the investigation of the efficacy of advanced oxidation processes (Fenton, ozonation and UV/H2O2) for decolorization of reactive azo dye (Blue CL-BR) using bleach wastewater as possible source of H202. All the experiments were performed on the laboratory scale set-up. The results showed that colour removal efficiencies by UV or bleach (H2O2) alone were not so effici...

Low density lipoprotein (LDL) isolated from human plasma anticoagulated with EDTA (EDTA/LDL) was 4-fold more resistant to oxidation by reagent H2O2, as assayed by the thiobarbituric acid (TBA) assay, than LDL prepared from plasma anticoagulated with citrate (CDP/LDL). The LDLs required 1-3 mM H2O2 for maximal oxidation by this assay, and ED50S were 1.7 X 10(-3) M for EDTA/LDL and 4.5 X 10(-4) M...

background: many studies have been published on the antioxidative effects of boric acid (ba) and sodium borates in in vitro studies. however, the boron (b) concentrations tested in these in vitro studies have not been selected by taking into account the realistic blood b concentrations in humans due to the lack of comprehensive epidemiological studies. the recently published epidemiological stu...
