Objective: The role of herbs against the free radicals have been put forth recently in combating many diseases. The aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of Tinospora cordifolia (SETc). Materials and Methods: SETcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydr...

background & aim: drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. in this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. experimental: this study was done in an experimental greenhouse, i.a.u., shahrekord branch, iran at...

Embryos were transferred from crossbred donor gilts to eight Duroc, nine Yorkshire and eight crossbred recipient gilts to determine differences in uterine capacity among genetic groups. Donor gilts were injected IM with 750 IU of PMSG on Day 16 (onset of estrus = Day 0). Donors and recipients were mated 12 and 24 hr after onset of estrus. Embryos were recovered on Day 4 and were deposited into ...

Background: The cigarette compounds are associated with the increase in the incidence of oral cancer andprecancerous lesions. Salivary antioxidant system plays an important role in anti-carcinogenic capacity ofsaliva. Cotinine, a nicotine metabolite, has a longer half-life in comparison with nicotine and is a suitablemarker for exposure to cigarette smoke. This study aims to measure total antio...

The aim, and main contribution, of this paper is to propose a fine-tuned fast approximator, based on neural networks, that uses aggregated traction system information as inputs and outputs. This approximator can be used as an investment planning constraint in the optimization. It considers that there is a limit on the intensity of the train traffic, depending on the strength of the power system...

Helicobacter pylori chronically colonises half of the world's human population and is the main cause of ulcers and gastric cancers. Its prevalence and the increase in antibiotic resistance observed recently reflect the high genetic adaptability of this pathogen. Together with high mutation rates and an efficient DNA recombination system, horizontal gene transfer through natural competence makes...
