Blood volatile organic compounds as potential biomarkers for poly cystic ovarian syndrome (PCOS): An animal study in the PCOS rat model.

Polycystic ovary syndrome (PCOS) as a common metabolic and endocrinological disorder can affect the metabolic profile in biological fluids. We studied the profile of blood volatile organic compounds (VOCs) in rats with PCOS and controls to identify potential specific biomarkers of blood VOCs in PCOS rats. For this purpose, 30 female adult Wistar rats were assigned to two groups: control and PCOS groups.

Modified magnetic nanoparticles by PEG-400-immobilized Ag nanoparticles (FeO@PEG-Ag) as a core/shell nanocomposite and evaluation of its antimicrobial activity.

Background: Noble metal nanoparticles, due to their good physicochemical properties, have been exploited in biological applications. Among these metals, nanosilver has attracted great attention because of its optical properties and broad-spectrum antimicrobial activities with no drug tolerance.

Purpose: The present study has attempted to conduct chemical synthesis of FeO@PEG-Ag core/shell nanocomposites in aqueous solutions through co-precipitation of Fe and Fe ions, encapsulating the iron oxide core by poly (ethylene-glycol) (PEG) improve its hydrophilicity and biocompatibility, and immobilizing silver ions by application of NaBH as a reducing agent.

Fabrication and characterization of platelet-rich plasma scaffolds for tissue engineering applications.

Platelet-Rich Plasma (PRP), as a rich source of growth factor, can form a fibrin gel that recapitulates the extracellular matrix of the tissues. The aim of this study was to evaluate the effects of different concentrations of CaCl on the PRP scaffold structure which in turn could change the cell's behavior. PRP was mixed with 2.
