nowadays, environment-sensitive smart drug delivery systems have found diverse applications in pharmaceutical science and technology. these systems can respond to the environment stimuli such as temperature, pressure, ph, light, electrical and magnetical fields and etc. they can release the proper amount of drug in human body. among these systems, special attention and much research works have ...

Current drug-eluting stent (DES) technology is not optimized with regard to the pharmacokinetics of drug release, more research on the drug-eluting stent design and flux of drug release to the arterial wall is necessary. Considering a three-dimensional (3D) cylindrical mathematical model, a novel free drug mass transfer release has been formulated and applied for better estimation of the drug c...

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...

background: obesity seems to be associated to migraine headache. increase in body fat, especially in gluteofemoral region, elevates adiponectin and leptin secretion which in turn impair inflammatory processes that could be contributing to migraine risk. this study was designed to assess the relationship between body composition and risk of migraine for the first time. methods: in this cross-sec...

In this paper, we have considered the problem of rotating, magnetohydrodynamic heat and mass transfer by free convective flow past an exponentially accelerated isothermal vertical plate in the presence of variable mass diffusion. While the temperature of the plate is constant, the concentration at the plate is considered to be a linear function with respect to time t. The plate is assumed to be...

the binding, release and oxidation of oxygen occur at the heme group iron ion. hemoglobinoxidation-reduction studies have been previously performed using spectroelectrochemistry (sec) andhave provided insight into the hemoglobin electron transfer process and more specifically, into theheme group electronic factor and subunit interaction influences. in this study, the number of fullerenecarbon a...
