An increase in the intracellular Ca” concentration of human erythrocytes results in profound morphological changes and loss of plasma membrane in the form of small vesicles [ 1,2]. It is of interest to determine whether this behaviour could be related to a Ca2+-induced instability in the bilayer structure of the membrane lipid. We have therefore examined the influence of Ca2+ on model membrane ...
A folate-polyethylene glycol-chitosan derivative was synthesized and its structure was characterized. An optimal perfluorooctyl bromide nanocore template was obtained via utilizing the ultrasonic emulsification method combining with orthogonal design. The targeted nanoparticles containing targeted shell of folate-polyethylene glycol-chitosan derivative and perfluorooctyl bromide nanocore templa...
Background and Objective: Leishmaniasis is a public health problem caused by different types of Leishmania. The induction of apoptosis in infected macrophages is one of the main mechanisms for the escape of the parasite from the immune system. Preventing apoptosis and enhancing the ability to kill macrophages can be effective in treating or controlling leishmaniasis. In this study, the effect ...
The intact acrosome of the Mytilus edulis spermatozoon consists of a conical vesicle, the basal side of which is deeply invaginated so that the whole vesicle forms a sheath around a very slender axial rod, about 2.7 micro long, inserted in a tube passing through the nucleus. The annular base of the acrosomal vesical is filled with a homogeneous substance; the outer wall of the vesicle is lined ...
Macroor micro-porous chitosan membranes have been utilized as adsorptive membrane for the removal of metal ions, organic macromolecules or bioseparation of protein mixtures. The removal or separation mechanism is not based on physical size retention but based on the high adsorption capability of chitosan to the target solutes. For this purpose, it is important that large macro or micro pores an...
In Vivo Assessment of Clobetasol Propionate-Loaded Lecithin-Chitosan Nanoparticles for Skin Delivery
The aim of this work was to assess in vivo the anti-inflammatory efficacy and tolerability of clobetasol propionate (CP) loaded lecithin/chitosan nanoparticles incorporated into chitosan gel for topical application (CP 0.005%). As a comparison, a commercial cream (CP 0.05% w/w), and a sodium deoxycholate gel (CP 0.05% w/w) were also evaluated. Lecithin/chitosan nanoparticles were prepared by se...
سابقه و هدف: کلامیدیا تراکوماتیس یک باکتری داخل سلولی اجباری با اهمیت کلینیکی بالا میباشد که عفونتهای انسانی ناشی از این باکتری ترجیحاً چشمها و دستگاه تناسلی را گرفتار میکنند. کلامیدیا تراکوماتیس، شایعترین عامل کونژنکتیویت فولیکولار مزمن و عامل 20 درصد موارد کونژنکتیویت حاد می باشد. از آنجاییکه تشخیص سریع می تواند در کاهش عوارض طولانی مدت بیماری موثر باشد در این تحقیق ما بر آن شدیم که روشهای مخ...
