Magnetic water-soluble hyperbranched polyol functionalized graphene oxide nanocomposite (MWHPO-GO) was successfully prepared and applied to water remediation in this paper. MWHPO-GO was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), magnetization curve, zeta potential, scanning electron microscope (SEM) and transmissio...

background: the cardioprotective effect of ischemic preconditioning has been known for many years. since the temporary ischemia in the heart may cause lethal cardiac effects, the idea of creating ischemia in organs far from the heart such as limbs was raised as remote ischemic preconditioning (ripc). we hypothesized that the extension of ripc has more cardioprotective effect in patients undergo...

objective: hypoxia-inducible factor (hif)-1 plays an essential role in the body’s response to low oxygen concentrations and regulates expression of several genes implicated in homeostasis, vascularization, anaerobic metabolism as well as immunological responses. increased levels of hif-1α are associated with increased proliferation and more aggressive breast tumor development. lactobacilli have...

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...

psa is a 33-kda serine protease that is produced predominantly by prostate epithelium. however, it has been shown that about 30-40% of female breast tumors produce psa and its production is associated with the presence of estrogen and progesterone receptors. we have now developed a new tissue culture system to study psa production in breast cancer and its association with prognostic factors suc...

Background: The cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. This study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. Methods: Five groups (7 each) of male Sprague-Dawley rats, including a control group, a diabetes (induced by Streptozocin and Nicotinamide)...

The quark masses are fundamental parameters of the QCD lagrangian which are not predicted by the theory. Their definition is not unique since quarks are not observed as free particles, but confined inside hadrons. Therefore, the use of dynamical expressions is mandatory in order to determine the masses of the quarks. The perturbative pole mass, Mq, and the running mass in the MS scheme, mq, are...

This reaserch aims at functionalizing magnetic mesoporous silica with methacrylic acid-3-aminopropyltriethoxysilane (Fe3O4@MCM-41@MAA-APTES) applied for removal of methylene blue from aqueous solution. Several variables (such as pH, dye concentration, adsorbent amount and contact time) have been investigated. Under optimum conditions, maximum capacity of 87.71 mg g-1 of MB was obtained for the ...
