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...

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...

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...

The roles of oxidative stress on nuclear factor (NF)‑κB activity and cardiomyocyte apoptosis during heart failure were examined using the antioxidant N‑acetylcysteine (NAC). Heart failure was established in Japanese white rabbits with intravenous injections of doxorubicin, with ten rabbits serving as a control group. Of the rabbits with heart failure, 12 were not treated (HF group) and 13 recei...

This study was conducted to investigate how the activity and expression of certain paramount antioxidant enzymes respond to grape seed extract (GSE) addition in primary muscle cells of goats. Gluteal primary muscle cells (PMCs) isolated from a 3-week old goat were cultivated as an unstressed cell model, or they were exposed to 100 µM H2O2 to establish a H2O2-stimulated cell model. The activitie...

Learning and memory abilities are associated with alterations in gut function. The two-way proanthocyanidins-microbiota interaction in vivo enhances the physiological activities of proanthocyanidins and promotes the regulation of gut function. Proanthocyanidins extracted from lotus seedpod (LSPC) have shown the memory-enhancing ability. However, there has been no literature about whether Lactob...

This study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. In this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. In the first phase after the saliva collection, one group of patients took 500 mg of vitamin C powder, for 3 weeks. Then, saliva of...

results administration of dse significantly increased serum paraoxonase and arylesterase activities in treated hypercholesterolemic groups compared to untreated ones. there was a significant difference in the taoc of serum between the normal diet and hypercholesterolemic groups. however, dse did not change the taoc in hypercholesterolemic groups significantly. conclusions dse increases serum pa...
