We have examined the adsorption behaviors of carbon monoxide (CO) molecule on TiO2 anatase supported Au overlayers. The results of density functional theory (DFT) calculations were used in order to gain insights into the effects of the adsorption of CO molecules on the considered hybrid nanostructures. We have investigated different adsorption geometries of CO over the nanoparticles....

Background: Previous studies have reported the antifertility activities of sulfonamides. This study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats.Methods: A total of 54 rats were randomly divided into 9 groups (n=6). Group I served as the control and group II (vehicle) received saline. Other groups, III to IX, r...

the application of chemotherapy in cancer treatment has been limited due to cause side effects such as toxicity against normal cells and drug resistance. in recent years, numerous studies have been focused on using natural products with chemotherapeutic drugs to enhance therapeutic efficiency and reduce cytotoxicity. on the other hand, encapsulation of drugs into nanoparticles (nps) can improve...

Background: Knowing the pattern of carbon monoxide (CO) poisoning in each region is vital for enhanced health planning. This study was designed to evaluate the epidemiologic pattern of unintentional acute CO poisoning in major cities of Fars province, southwest of Iran.  Methods: This one-year cross-sectional study was carried out on unintentional CO poisoning incidents in Fars province, Iran,...

in this paper, surface and piezoelectric effects on the vibration behavior of nanowires (nws) are investigated by using a timoshenko beam model. the electric field equations and the governing equations of motion for the piezoelectric nws are derived with the consideration of surface effects. by the exact solution of the governing equations, an expression for the natural frequencies of nws with ...

statins are most effective pharmacologically agents to decrease total plasma cholesterol level by competitive inhibition of hmg-co a reductase. apart from the well-known ldl and cholesterol lowering effect, statins have been postulated to exert other beneficial effects also called pleotropic or non-lipid effects. better understanding of various pleotropic effects of statins has prompted a new s...

In this study, Co (III) salen complex was synthesized and immobilized onto the surface of Fe3O4@SiO2 magnetic nanoparticle. The heterogeneous nanocatalyst was characterized by different techniques including X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), nitrogen adsorption−desorption isotherm (BET), ...
