background: this study aims to investigate the effect of antioxidants supplement on clinical outcomes and antioxidant parameters in rheumatoid arthritis (ra). methods: the pre‑post study was conducted on 40 female patients with ra in 12 weeks that taken daily one “selenplus” capsule contained 50 μg selenium, 8 mg zinc, 400 μg vitamin a, 125 mg vitamin c, and 40 mg vitamin e. about 5 ml venous b...

The production of tomato under low-temperature stress in the open fields is a challenge faced by many farmers. current study compares use different ethylene treatments to accelerate fruit ripening during two successive seasons cold stress. included foliar application ethrel (2500, 5000, and 7500 ppm) field at mature green stage, dipping collected fruits solution (1000, 1500, 2000 right after ha...

background : periodontal disease is a common oral disease, which oxidative stress plays an important role in its pathogenesis. the onset and progress of this disease is influenced by balance between oral biofilm and host response. regarding with the role of oxidative stress in the pathogenesis of periodontal disease and reduction of total antioxidant capacity in patients with periodontal diseas...

Proadrenomedullin N-terminal 20 peptide (PAMP) derives, along with adrenomedullin (AM), from prepro-AM. AM has been reported to modulate the activity of the hypothalamic-pituitary-adrenal (HPA) axis, and this study aimed at ascertaining whether PAMP exerts similar effects. PAMP was subcutaneously administered to non-stressed and stressed rats, and the plasma concentrations of ACTH and corticost...

abiotic stress such as cold and drought has adverse effects on plants growth and development. abiotic stress resistance is one of the most important goals in plant breeding. this goal can be achieved through transcription factor gene transfer to plants. recent studies show many successes in improving abiotic stress resistance by use of transcription factor gene transfer. the objective of the re...

Cold stress is an ‎important limiting factor for cereal production. Barley is a host species for arbuscular mycorrhizal fungi (AMF) with a high genetic diversity in response to cold stress. In order to explore the mechanisms for the ameliorative effect of AMF under cold stress, an experiment was undertaken using completely randomized block design with three factors including temperature treatme...

It has been estimated that about 20% of men and 25% of women between the ages of 65 and 74 have some degrees of chronic kidney. This complication is attributed to oxidative stress. Oxidative stress is an important factor contributing to kidney damage by increasing production of oxidants, particularly insufficiency of endogenous antioxidant defense system. Medicinal plants antioxidants are able ...

The effect of cold-immobilized stress on the gamma-aminobutylic acid (GABA)/benzodiazepine (BZP) receptor complex in the rat striatum was examined. The stressful manipulation induced a significant decrease in the amount of [3H]muscimol binding sites in the striatal particulate fraction. On the other hand, [3H]flunitrazepam (FLN) binding and the enhancing effect of FLN or secobarbital on the [3H...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...
