Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

cross-linked polymeric organogels have attracted much attention in recent years. most synthesized organogels are based on low molecular weight or denderitic materials. the study focuses on the preparation of an alcohol absorbent organogel based on 2-acrylamido-2-methylpropane sulphonic acid (amps) through cross-linking polymerization. polyethylene glycol diacrylate-400 and ammonium persulphate ...

Abstract In this paper gelatin beads reinforced with natural hemp hurd have been produced as pH sensitive devices for the release of eugenol, green pesticide. The composites beads, a mean diameter about 1 mm, were obtained by polymer droplet gelation in sunflower oil. Thermal properties evaluated showing no noticeable difference after introduction hurd. Barrier demonstrated an improvement hydro...

DNA methylation is one of major epigenetic mechanisms by which regulate a panel gene expressions. An old but revisiting compound, 5-azacytidine, pyrimidine nucleoside analog cytidine that can inhibit methyltransferase, induce cell differentiation, and has direct cytotoxicity on abnormal bone marrow hematopoietic cells. Thus, systemic administration 5-azacytidine been approved for the treatment ...

In core–shell nanoparticle analysis, the determination of size distributions different particle parts is often complicated, especially in liquid media. Density matching introduced as a method for analyzing nanoparticles using Analytical Ultracentrifugation (AUC), making it possible to obtain core distribution dispersions. For this approach, density dispersion adjusted shell. Oil filled nanocaps...
