Background: N-acetylcysteine (NAC) is a putative antioxidant and has gained attention as a promising agent for chelating heavy metals including lead. Considering the animal studies results, we hypothesized that adding NAC to the treatment regimen may improve the success of treatment with lead chelators. Methods: A total of 46 patients who were lead-poisoned opioid addicts were divided into two ...

To study the influence of season on oxidative status of buffalo semen and their association with semen characteristics and seminal plasma proteins, ejaculates were collected twice a week in winter, summer and rainy seasons from six adult Bhadawari buffalo bulls. The neat semen was analyzed for semen characteristics immediately after collection and oxidative status viz. lipid peroxidation (LPO),...

Objective: Oxidative stress leads to reactive oxygen species (ROS) overproduction, which causes tissue injury in diabetic patients. The aim of this study was to evaluate the effects of Zataria multiflora extract on TNF-α, oxidative stress products, and insulin levels as well as lipid profile in diabetic rats. Materials and Methods: Rats were randomly divided into 6 groups of 10 animals. Diabete...

Recent studies have introduced seed priming with H2O2 as an effective technique to alleviate abiotic stresses in plants. In the current study, accomplished at Faculty of Sciences, Shahrekord University, seeds of medicinal plant Artemisia aucheri were primed with H2O2 (0, 10, 50, 90 and 140 µM) and grown under salt stress (0 and 150 mM NaCl) for one month. Results showed a decrease in H2O2 and m...

Seedlings of papaya (Carica papaya), cultivar Golden, were exposed to a nitric oxide donor, sodium nitroprusside (SNP), Papaya meleira virus (PMeV) and yeast (Saccharomyces cerevisiae, as a model fungal elicitor). The aim was to investigate the response of C. papaya to infection and the role of nitric oxide in this process. SNP alone led to a short lived (6 h) burst of peroxidase activity and a...

Bicarbonate anion, has a very high concentration in the calcareous soil, and in fact, is the main cause of chlorosis in calcareous soils. This study was conducted to evaluate eight soybean cultivars with iron deficiency and bicarbonate presence. The present research was carried out with the aim of assessing the effect of irrigation with water containing bicarbonate on enzyme activities and Fe a...

Quercetin is a typical flavonoid with diverse biological effects, attributable to its free radical scavenging activity. Bioavailability of quercetin aglycone and its glycosides is an important factor for its antioxidant activity in vivo. A severe limitation exists and is imputable to very poor absorption of quercetin when administered orally. To overcome this limitation, development of a value ...

Transitional metal oxide nanoparticles as advanced environment and energy materials require very well absorption performance to apply in practice. Although most metal oxides are based on crystalline, high activities can also be achieved with amorphous phases. Here, we reported the adsorption behavior and mechanism of methyl blue (MB) on the amorphous transitional metal oxide (Fe, Co and Ni oxid...

The effect of nano silica (50 mL L−1) and melatonin (75 µM) individually or in combination foliar applications on the morphophysiological, biochemical yield properties pea plants under salinity stress conditions was evaluated. Salt caused a remarkable decrease growth characteristics; for example, plant dry weight, height, number flowers plant−1, pods weight 100 green seeds protein concentration...

Depression and anxiety disorders are the most common mental health problems associated with oxidative stress. Although famous for its anxiolytic effect, antidepressant effect of valerian-hops combination was not previously studied, also relationship between sedative stress markers is unclear. The current research has two objectives: (1) to compare escitalopram (2) evaluate sedative/anxiolytic e...
