FeMn2O4 nanoparticles coated dual responsive temperature and pH-responsive polymer as a magnetic nano-carrier for controlled delivery of letrozole anti-cancer
Objective(s): For cancer cells, an efficient and selective drug delivery vehicle can remarkably improve therapeutic approaches. This paper focuses on the synthesis and characterization of magnetic MnFe2O4 NPs and their incorporation in a dual temperature and pH-responsive polymer, which can serve as an efficient drug carrier. Materials and Methods: MnFe2O4 NPs were synthesized by chemical co-pr...
متن کاملan application of fuzzy logic for car insurance underwriting
در ایران بیمه خودرو سهم بزرگی در صنعت بیمه دارد. تعیین حق بیمه مناسب و عادلانه نیازمند طبقه بندی خریداران بیمه نامه براساس خطرات احتمالی آنها است. عوامل ریسکی فراوانی می تواند بر این قیمت گذاری تاثیر بگذارد. طبقه بندی و تعیین میزان تاثیر گذاری هر عامل ریسکی بر قیمت گذاری بیمه خودرو پیچیدگی خاصی دارد. در این پایان نامه سعی در ارائه راهی جدید برای طبقه بندی عوامل ریسکی با استفاده از اصول و روش ها...
Hemolytic activity of pH-responsive polymer-streptavidin bioconjugates.
Drug delivery systems that increase the rate and/or quantity of drug release to the cytoplasm are needed to enhance cytosolic delivery and to circumvent nonproductive cell trafficking routes. We have previously demonstrated that poly(2-ethylacrylic acid) (PEAAc) has pH-dependent hemolytic properties, and more recently, we have found that poly(2-propylacrylic acid) (PPAAc) displays even greater ...
متن کاملA Novel Composite Membrane for pH Responsive Permeation
Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods Here, a kind of pH sensitive composite membrane containing different nanoparticle ...
متن کاملDevelopment of pH Sensitive Nanoparticles for Intestinal Drug Delivery Using Chemically Modified Guar Gum Co-Polymer
The aim of the research work was to chemically modify guar gum(GG) as a pH sensitive co-polymer and formulating intestinal targeting ESO nanoparticles (NPs) using the synthesized co-polymer. Poly acrylamide-grafted-guar gum (PAAm-g-GG) co-polymer was synthesized by free radical polymerization. Chemical modification of PAAm-g-GG by alkaline hydrolysis results in formation of a pH-sensitive co-po...
