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...

Tarnish and Corrosion behavior of three Commercial dental amalgams namely Am.1, Am.2, Am.3, have been investigated by utilizing in vitro tests. The corrosion and/or dissolution rate of the three dental amalgams were studied in 0.9 wt% NaCl Solution, artificial saliva and Ringers solution. Potentiodynamic polarization technique was employed to study cathodic and anodic polarization behavior, fro...

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...
