The present review discusses the potential use of solid lipid nanoparticles for brain drug targeting purposes. The state of the art on surfactant-coated poly(alkylcyanoacrylate) nanoparticles specifically designed for brain targeting is given by emphasizing the transfer of this technology to solid lipid matrices. The available literature on solid lipid nanoparticles and related carriers for bra...

Objectives We aimed to develop a sustained release system for an anti-TNFa drug in treatment of chronic inflammatory arthritis. A novel form of intra-articularly injectable etanercept (ETN) loaded poly(ε-caprolactone) (PCL) or methoxy poly(ethylene glycol)-poly(ε-caprolactone)methoxy poly(ethylene glycol) (MPEG-PCL-MPEG) microspheres (patent pending) were prepared to provide long term controlle...

Polymersomes made of amphiphilic diblock copolymers are generally regarded as having higher physical and chemical stability than liposomes composed phospholipids. This enhanced arises from the molecular weight polymer constituents. Despite their increased stability, bilayers solubilized by detergents in a similar manner to lipid bilayers. In this work, we evaluated poly(ethylene glycol)-block-p...

Atherosclerosis can affect the blood vessels in any region of body and stenosis (narrowing) be located on an artery that vascularize important organs, such as brain, abdominal organs or limbs. The endovascular surgery is a modern approach to vascular pathology through minimally invasive techniques (puncture, approach) it represents enrichment arsenal surgical brings considerable improvements po...

Partially purified preparations of mouse interferon, administered during the 2-day period following the administration of a toxic dose of 5-fluorouracil (FUra), yielded significant protection from mortality in BALB/c x DBA/2 F1 mice. Protection against FUra-induced toxicity was also observed when the interferon inducer polyinosinic-polycytidylic acid (poly I.poly C) was administered with FUra. ...

The research presented in this thesis focuses on the synthesis of three amphiphilic block copolymer systems containing poly(ethylene oxide) (PEO) blocks. The polymer systems were developed for use in biomedical applications. The first of these is a series of poly(ethylene oxide-b-oxazoline) (PEO-b-POX) diblock copolymers for use in the progress towards novel nonviral gene transfer vectors. Poly...

Modified poly(aspartic acid)/poly(vinyl alcohol) interpenetrating polymer network (KPAsp/PVA IPN) hydrogel for drug controlled release was synthesized by a simple one-step method in aqueous system using poly(aspartic acid) grafting 3-aminopropyltriethoxysilane (KH-550) and poly(vinyl alcohol) (PVA) as materials. The hydrogel surface morphology and composition were characterized by Fourier trans...

During the chemotherapy of cancer, drug resistance is the first issue that chemotherapeutic drugs cannot be effectively used for the treatment of cancers repeatedly for a long term, and the main reason for this is that tumor cell detoxification is mediated by GSH (glutathione) catalyzed by GST (glutathione-S-transferase). In this study, a GST inhibitor, ethacrynic acid (ECA), was designed to be...
