calendula officinalis (family compositae) flowers are recognized as safe substance for food use by food and drug administration. present study was aimed to determine the modulatory effect of floral extracts of c. officinalis administrations on mean blood glucose (mbg), per cent glycosylated hemoglobin (hba1c), lipid profile [(total cholesterol (tc), triglycerides (tg), low and high density lipo...

objective the aim of this study was to determine the effect of revival soymilk consumption and moderate exercise on vasomotor symptoms, total antioxidant capacity (tac) and alkaline phosphates activity in postmenopausal women. materials and methods in this study, daily for 3 months, 37 postmenopausal women (mean age = 52.2± 4.6 years) were randomly assigned to soymilk (n=15), exercise +soymilk ...

occurrenceofoxidative stress (os) following in vitro culture is inescapable. therefore, the aim of the present study was to determine the efficacy of coenzyme q 10 (coq 10 ) supplementation medium on developments and total antioxidant capacity (tac) of mouse vitrified pre-antral follicles. fresh and vitrified-warmed isolated preantral follicles from ovaries of 14-16 day s -old mice were cultured...

total phenolic contents (tpc) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of artemisia biennis willd were measured in this work. the antioxidant activity was investigated by three different methods: β-carotene bleaching (bcb) test, 2,2-diphenyl-1-picrylhydrazyl (dpph) radical scavenging method and ferrous ion chelating (fic) assay. amo...

conclusions it is concluded one week oral supplementation of curcumin has positive effects on selected indices of oxidative stress possibly via promotion of antioxidant capacity. results there was a significant increase in tac after supplementation (p < 0.001, es = 1. 42), and immediately after exercise (p = 0. 008, es = 1. 12) in c group compared with the p group. mda-tbars was significantly l...

this study was conducted to assess the effect of ginger supplementation on malondialdehyde (mda) level, as an oxidative stress marker, and total antioxidant capacity (tac) in broiler chicks. two hundred male 1-day-old chicks were assigned randomly to four dietary treatments (basal diet as control group and basal diet containing 2.5, 5.0 and 7.5 g/kg ginger, respectively), with five replicates a...

antibacterial, antifungal and antioxidant activities of methanolic crude extracts from aerial parts of four arnebia species namely arnebia fimbriopetala, arnebia linearifolia, arnebia garandiflora, arnebia tubata were screened. total phenolic contents were determined by folin-ciocalteu procedure and ranged from 2.2 ± 0.13 (a. fimbriopetala) to 1.6 ± 1.0 mg (arnebia tubata) gallic acid µmol equi...

the number of patients with end-stage renal disease is growing rapidly in asia. patients with end stage renal disease failure (esrd) undergoing long term hemodialysis (hd) are at risk for high oxidative stress. there is paucity of information with regard to oxidative stress during hd. therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...

background and objective: oxidative stress plays an important role in the pathogensis of various diseases, including lung cancer, chronic obstructive pulmonary disease, and atherosclerosis. total antioxidant capacity plays a significant role in the body’s antioxidant defense, so its assessment is a matter of the utmost importance. currently, assessment of this capacity is performed in various s...

Five antioxidant and two oxidative stress assays were applied to serum samples of 43 healthy males. The antioxidant tests showed different inter-assay correlations. A very good correlation of 0.807 was observed between the ferric reducing ability of plasma (FRAP) and total antioxidant status (TAS) assay and also a fair correlation of 0.501 between the biological antioxidant potential (BAP) and ...
