The silver nanoparticles (AgNPs) have been applied as an antibacterial agent in consumer products, cosmetics, and food industries. In this present work, AgNPs were synthesized various mediums of polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), chitosan using the pulse laser ablation synthesis method. Experimentally, a Nd:YAG beam (1064 nm, 7 ns, 30 mJ) was directed mirror focused quartz l...

background: the aim of present study is to evaluate the effect of polyvinyl pyrrolidone (pvp) routinly used during icsi procedure on sperm membrane integrity, and sperm chromatin status. materials and methods: this study was carried out on 21 semen samples from the infertile men referring to isfahan fertility and infertility center. the processed semen samples were divided into two portions. on...

The objective of this investigation was to define the splanchnic hemodynamic effects of parenterally administered glucagon in a canine model. Measurements in six dogs at baseline and at 10, 20, and 30 min during constant intravenous infusion of glucagon at 1 pg/kglmin included: Cardiac output (CO), mean arterial pressure, total peripheral vascular resistance (TPR), superior mesenteric artery fl...

PURPOSE To examine the effectiveness and safety of photoselective vaporization of the prostate (PVP) with the 120 W high-performance system (HPS) Greenlight laser procedure in benign prostatic hyperplasia (BPH) patients taking oral anticoagulant medications. MATERIALS AND METHODS This study was conducted on BPH patients taking oral anticoagulant medications form March 2009 to December 2010. G...

Alone and combined effects of cyclodextrins (βCD and HPβCD), surfactant (Tween-80) and PVP on the solubility and dissolution rate of etoricoxib were evaluated in a series of 2 factorial design. The complexes of etoricoxib – CDs (βCD and HPβCD) were prepared with and without Tween-80 and PVP by kneading method as per 2 factorial designs. The solubility of etoricoxib in eight selected fluids cont...

Polymers are materials composed of macromolecules characterized by duplicates smaller molecules that covalently bonded together to provide a set properties. Corrosion inhibition such compounds is usually attributed their adsorption on the metal-solution interface. The effect different sizes polyvinylpyrrolidone (PVP) corrosion carbon steel (C-steel) in solutions perchloric acid was investigated...

The study investigates ibuprofen with wax-like properties as a multifunctional agent (as an active component and as a melt binder). Binding efficiency was compared with granules prepared by wet granulation using polyvinylpyrollidone (PVP K-30) as a binder for micromeritic, physical and mechanical properties such as angle of repose, particle size distribution Carr's index, Hausner's ratio, crush...

The objective of the present investigation was to study the influence of polyethylene glycol 4000 (PEG) and polyvinylpyrrolidone K30 (PVP) on in vitro dissolution of etoricoxib from solid dispersions. Preliminary studies were carried out using a physical mixture of the drug and carriers. Solid dispersions were prepared using the solvent evaporation method. A 32 factorial design was adopted in t...

Peptidoglycan lytic enzymes (endolysins) induce bacterial host cell lysis in the late phase of the lytic bacteriophage replication cycle. Endolysins OBPgp279 (from Pseudomonas fluorescens phage OBP), PVP-SE1gp146 (Salmonella enterica serovar Enteritidis phage PVP-SE1) and 201φ2-1gp229 (Pseudomonas chlororaphis phage 201φ2-1) all possess a modular structure with an N-terminal cell wall binding d...

Silver nanoparticles (AgNPs) are being widely applied as topical wound materials; however, accumulated deposition of silver in the liver, spleen, and other main organs may lead to organ damage and dysfunction. We report here that low molecular weight chitosan-coated silver nanoparticles (LMWC-AgNPs) are effective against methicillin-resistant Staphylococcus aureus (MRSA), have better biocompati...
