objectives: platelets are anucleated fragments derived from megakaryocytes. it has been demonstrated that platelets play a role in hemostasis and innate immunity. in addition, platelets have a cd40 ligand which is an important molecular marker in motivating immune cells. thus, platelets also have a role in adaptive immunity as seen by their ability to activate b cells. since human platelet micr...

Chitosan was prepared from crab shell. Different derivatives of chitosan e.g. phosphate, cyanoethyl and carboxymethyl chitosan are prepared. Molecular structure of chitosan and its derivatives was fallowed by infrared spectroscopy. A new band at 1715cm -1 (carboxyl group), at 2253cm -1 (cyano group) and at 1200cm -1 for (c-o-p) in spectra of carboxymethyl chitosan, cyanoethyl chitosan and chito...

OBJECTIVES In this study, we evaluated the cellular origins and thrombogenic potential of microparticles. BACKGROUND Human atherosclerotic plaques contain submicron vesicles (microparticles) released during cell activation or apoptosis. METHODS Microparticles were purified from plaques and platelet-free plasma from 26 patients undergoing carotid endarterectomy. Flow cytometry analysis revea...

This article describes the preparation and characterization of anticancer drug-loaded poly(lactide-coglycolide) (PLGA) microparticles. PLGA microparticles loaded with doxorubicin HCl (DOX) were prepared via o/w emulsion solvent evaporation. The release characteristics, encapsulation efficiency, size, and morphology of the PLGA microparticles were also determined. A cytotoxicity test was perform...
