Soil and water salinity in semi-arid regions such as Iran have been a important threat for plant growth and agriculture. It is demonstrated that TiO2 nanoparticles can improve plant growth and increase stress tolerance in plants. Therefore, in current study, a pot experiment was conducted as factorial with completely randomized design to evaluate the effect of 3 levels of salinity (0, 50, ...
introduction : tardive dyskinesia is one of the major side effects of long-term neuroleptic treatment. increased reactive oxygen species and oxidative stress has been proposed as possible etiopathologic mechanisms. ginkgo biloba extract (egb) is a natural antioxidant. we investigated the effects of ginkgo biloba extract on neuroleptic-induced orofacial dyskinesia in rats, a potential animal mod...
One of the main criteria for salt tolerance is cell membrane stability under stress. Reactive oxygen species (ROS), activity of lipoxygenase (Lox) and lipid peroxidation are considered to be destructive to cell membrane under salt stress. In this study, the effects of 0, 75 and 150 mM NaCI, over a period of 14 days on the activity of lipoxygenease, the amount of hydrogen peroxide (H2O2) and mal...
Background: physical exercise could induce lipid peroxidation as a result of oxidative stress. And intake of antioxidant compound may alleviate this stress by enhancing antioxidant defense. This study aimed to investigate the effect of vitamin E supplementation as an antioxidant on the lipid peroxidation and serum total antioxidant capacity following exhaustive continuous aerobic exercise in ...
Nanoparticles of titanium increase cell growth by improvement of photosynthetic and nitrogen metabolism and therefore, caused an increasing in weight of the plant. This re-search was conducted to evaluate seed yield and biochemical traits of bread wheat affected by different levels of titanium dioxide Nanoparticles in Ahvaz region, Khuzestan province, located at southwestern Iran by factorial e...
Cadmium (Cd) is a heavy metal that causes oxidative stress in plants. In this study toxicity effect of Cd on Silybum marianum was investigated. Four treatments of CdCl2 (0, 300, 600, 400 and 900 μM) were evaluated in five replications using complete random design. Results of tolerance stress index severity of Cd stress on plants under various levels of treatments. Shoot dry weight, leaf area, c...
Drought stress is a serious adverse factor that limits sunflower growth and productivity. The stress induces a range of physiological and biochemical responses in sunflower. So, evaluation of defense systems is important for producing resistant cultivars. In this study, physio-biochemical changes and antioxidant enzymes activitiesof six sunflower lines were evaluated under normal and irrigation...
Background & Aim: Ulcer index is one of the most common diseases among people. Current therapies include acid secretion inhibitors which have various side effects. Herbal medicines are considered as adjuvant therapy for this disease. Hydroalcoholic extract of Thymus daenensis has various components such as flavonoids which contribute to gastroprotection. Experimental: 35 <em...
This critique points out that a number of possible alterations in cell metabolism could lead to changes in membrane structure and that the observed effects might not necessarily play a primary role in the physiology of aging. Experimental approaches, while not simple, should distinguish causes of altered membrane asymmetry from its consequences. THE idea that cross-linking agents might play a r...
