introduction: the use of antioxidants before high-intensity training, which leads to the release of free radicals and muscle injuries, can result in reduced damage during exercise. accordingly, in this study, we aimed to evaluate the effect of selenium supplement intake on oxidative stress, following exhaustive aerobic exercise among young physically-active females. methods: in this quasi-exper...

aloe vera is a medicinal plant as antioxidants reduce cell damage and used. the purpose of this study was to determine the effect of aloe vera on lactate de-hydrogenase after a period of aerobic exercise in male athletes.methods this study applied the method according to the nature of the study, based on semi-empirical research and a review of the pre-test, post-test supplements and placebo gro...

objective(s): carbon nanotubes have unique mechanical, electrical, and thermal properties, with potential different applications in nanomedicine, electronics, and other industries. these new applications of carbon nanotubes in different industries lead to the increased exposure risk of nanomaterials to human. up to now, all aspects of carbon nanotubes toxicity are not completely clear following...

Streptococcus cremoris was grown in pH-regulated batch and continuous cultures with lactose as the energy source. During growth the magnitude and composition of the electrochemical proton gradient and the lactate concentration gradient were determined. The upper limit of the number of protons translocated with a lactate molecule during lactate excretion (the proton-lactate stoichiometry) was ca...

BACKGROUND The rate of extra-hepatic lactate production and the route of influx of lactate to the liver may influence both hepatic and extra-hepatic lactate exchange. We assessed the dose-response of hepatic and extra-hepatic lactate exchange during portal and central venous lactate infusion. METHODS Eighteen pigs randomly received either portal (n=5) or central venous (n=7) lactate infusion ...

Despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (BM) before organism growth in the culture medium-are missing. Therefore cerebrospinal fluid (CSF) lactate levels were evaluated as a possible means of differentiating the two clinical entities. This was a retrospective study....

Abstract Objective Removing plasma from the platelet concentrate (PC) medium could be an effective way to increase the safety of this product. The goal of this study was to compare PC stored in plasma or in an additive solution (Composol) with in vitro testing. Materials and Methods Fifty-four single donor PCs were prepared from Iranian Blood Transfusion Organization (IBTO). Each PC unit wa...
