Chinese medicinal herbs have been consumed for thousands of years for the purpose of healthy aging. Lycium barbarum is valued in Chinese culture for its benefits to anti-aging, vision, kidney and liver. Recent studies showed that extracts from L. barbarum possess biological activities including anti-aging, anti-tumor, immune-stimulatory and cytoprotection. Most of these studies emphasized that ...

Evidences that higher natural antioxidant (NA) intake provides protection against cardiovascular disease (CVD) are contradictory. Oxidative-induced endothelial cells (ECs) injury is the key step in the onset and progression of CVD and for this reason the cellular responses resulting from NA interaction with ECs are actively investigated. This study was designed to investigate the direct impact ...

1. Diabetic neuropathy is one of the most common complications of diabetes and oxidative stress has been implicated to play a major role in its pathophysiology. 2. In the present study, we targeted oxidative stress using trolox, an anti-oxidant, in streptozotocin-induced diabetic neuropathy in rats. 3. Compared with control rats, diabetic rats showed significant deficits in motor nerve conducti...

The relationship between exercise training and nitric oxide-related parameters was examined in a cross-sectional study and an intervention study. A cross-sectional study using 184 employees was conducted to observe the association of exercise habits with serum arginase (ELISA and activity), l-arginine, l-citrulline, l-ornithine, NOx, exhaled nitric oxide, blood pressure, FEV1%, hs-CRP, HDL-chol...

The total antioxidant activities of seven different vegetables were measured by FRAP method together with their estimation of total phenolic content by Folin-Ciocalteau method. Coriander and tomato belonged to high antioxidant activity group. In the medium group; capsicum, carrot and onion scored anti-oxidant activity of 5.65, 3.46 and 4.24 μ M Fe2+ /g FW respectively. Cucumber and radish were ...

Several therapeutic effects including diuretic, anti-pyretic and anti-scurvy have been reported for Portulaca oleracea. In previous studies the analgesic, anti-inflammatory, anti-hypertensive, anti-oxidant, muscle relaxant effects and neuropharmacological effects of the aqueous extract of Portulaca oleracea have been demonstrated on experimental animals. In the present study the antitussive eff...

Abstract: Background: Biocatalysis in organic solvents has several benefits over aqueous solvents, including solubility of substrates, ease workup, separation the product, and, certain cases, reusability biocatalysts. Materials and Methods: A simple, effective, environmentally friendly technique for synthesizing pyrazoles been established, which involves cyclo condensation chalcones isonicotini...

Oxidants play an important role in homeostatic function, but excessive oxidant generation has an adverse effect on health. The manipulation of Reactive Oxygen Species (ROS) can have a beneficial effect on various lung pathologies. However indiscriminate uses of anti-oxidant strategies have not demonstrated any consistent benefit and may be harmful. Here we propose that nuanced strategies are ne...

AIMS This study was carried out to assess the protective and anti-oxidant activities of the methanolic extract of Tribulus terrestris fruits (METT) against sodium valproate (SVP)-induced testicular toxicity in rats. MATERIALS AND METHODS Fifty mature male rats were randomly divided into five equal groups (n = 10). Group 1 was used normal (negative) control, and the other four groups were into...
