the aim of the present work was to assess the feasibility of accononmc8-2ep/nf as a bioadhesive material for developing controlled release gastroretentive microsponges of loratadine. modified emulsion-solvent diffusion method was employed for the preparation of microsponges (f1-f9) based on 32 factorial design. the amount of ethyl cellulose (ec) and polyvinyl alcohol (pva) were selected as inde...

objective(s): to study the effect of cardiopulmonary bypass (cpb) on nuclear factor-kappa b (nf-кb) and cytokine expression and pulmonary function in dogs. materials and methods: twelve male mongrel dogs were divided into a methylprednisolone group (group m) and a control group (group c). all animals underwent aortic and right atrial catheterization under general anesthesia. changes in pulmonar...

alcoholic liver disease (ald) is the main cause of chronic liver disease across the world and can lead to fibrosis and cirrhosis. the etiopathogenesis of ald is related to ethanol-induced oxidative stress, glutathione reduction, abnormal methionine metabolism, malnutrition, and production of endotoxins that activate kupffer cells. curcumin is an active ingredient of the rhizome of turmeric. the...

Anion modification and trace metal doping have been widely demonstrated to unique advantages in regulating both electrocatalytic activity the electronic structure of non-precious materials. Developing a simple practical preparation strategy is critical, but it still faces challenges. In this paper, novel type dual-modification approach put forward rationally design S, Pt-CoNi material, which ca...

Phase sensitive amplifiers (PSA), contrary to usual phase insensitive (PIA), are in principle capable achieve noiseless amplification, i.e. exhibit a quantum-limited noise figure (NF) of 0 dB. When implemented using four-wave mixing (FWM) nonlinear fiber, extra waves can be generated by undesired FWM processes, which may introduce input ports for vacuum fluctuations, thus potentially degrading ...
