the aim of this study was to define the electrocardiogram (ecg) changes following the moderate to severe co intoxication in rats, and also evaluating the effect of erythropoietin (epo) on observed cardiac disturbances. the growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. wistar rats were exposed...

The full potential health impact from the emissions of biomass fuels, including wood pellets, during storage and transportation has not been documented in the open literature. The purpose of this study is to provide data on the concentration of CO(2), CO and CH(4) from wood pellets stored in sealed vessels and to develop a kinetic model for predicting the transient emission rate factors at diff...

BACKGROUND The required dose of anesthetics is generally smaller in patients with low cardiac output (CO). A high CO decreases the blood concentration of anesthetics during induction and maintenance of anesthesia. However, a high CO may also shorten the delivery time of anesthetics to the effect site, e.g. the brain. We assessed the time required for induction of anesthesia with propofol admini...

lu3+/yb3+ and lu3+/er3+ co-doped sb2se3 nanomaterials were synthesized by a co-reduction method in hydrothermal condition. powder xrd patterns indicate that the lnxln′xsb2-2xse3 ln: lu3+/yb3+ and lu3+/er3+ crystals (x= 0.00-0.04) are isostructural with sb2se3. the cell parameters were increased for compounds upon increasing the dopant content (x). sem and tem images show that co-doping of lu3+/...

In the Coupled Model Intercomparison Project Phase 5 (CMIP5), the model-mean increase in global mean surface air temperature T under the 1pctCO2 scenario (atmospheric CO(2) increasing at 1% yr(-1)) during the second doubling of CO(2) is 40% larger than the transient climate response (TCR), i.e. the increase in T during the first doubling. We identify four possible contributory effects. First, t...

Corn cob as a low cost adsorbent was used in the present work for the removal of toxic heavy metal Co2+ from aqueous solutions. Bath experiments were used to determine the best adsorption conditions. The equilibrium adsorption level was determined as a function of solution pH, temperature (T), contact time (tc), initial adsorbate concentration, and adsorbent dosage. Effective removal of metal i...

Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...

clarithromycin (cla), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. the aim of this investigation was to prepare cla nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (sls) and polyvinyl pyrrolidone (pvp) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. different weight rati...

A difference in salt concentration in two solutions separated by a membrane leads to an electrical potential difference across the membrane, also without applied current. A literature study is presented on proposed theories for the origin of this membrane potential (ϕm). The most well-known theoretical description is Teorell-Meyer-Sievers (TMS) theory, which we analyze and extend. Experimental ...

Background Specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (ESCs) differentiation. In this study,the effects of bone morphogenetic protein 4 (BMP4) and mouse embryonic fibroblasts (MEFs) co-culture system on germ cell differentiation from mouse ESCs were studied. MaterialsAndMethods Cell suspension was prepared from one-day-old embryoid bo...
