Chlamydia trachomatis is a very common sexually transmissible infection in both developing and developed countries. A hallmark of C. trachomatis infection is the induction of severe inflammatory responses which play critical roles in its pathogenesis. Antibiotics are the only treatment option currently available for controlling C. trachomatis infection; however, they are efficacious only when a...

This feature article introduces our recent work on understanding the roles played by citrate and poly(vinyl pyrrolidone) (PVP) as capping agents in seed-mediated syntheses of Ag nanocrystals with controlled shapes. We have demonstrated that citrate and PVP selectively bind to Ag(111) and Ag(100) surfaces, respectively, and thus favor the formation of Ag nanocrystals enclosed preferentially by {...

BACKGROUND High-level evidence to support the use of photoselective vaporization of the prostate (PVP) is limited. OBJECTIVE Assess the efficacy and safety of GreenLight HPS 120-W laser PVP compared with transurethral resection of the prostate (TURP). DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial was performed with 50 patients having lower urinary tract symptoms due to benig...

BACKGROUND Outcomes of liver resection for hepatocellular carcinoma (HCC) have improved owing to better surgical techniques and patient selection. Portal hypertension may influence outcome but the preoperative definition and role of portal hypertension are far from clear. The aim of this study was to elucidate the influence of portal venous pressure (PVP) measured directly during surgery on out...

The recent study's objective was to prepare and evaluate the Repaglinide (RG) solid dispersion. RG is poorly water soluble, BCS class II drug. dispersion (RG-SD) prepared by solvent evaporation method using different proportion of PVP K30. RG-SD evaluated for solubility studies, drug content, in vitro dissolution, DSC studies XRD studies. results indicate that exists amorphous form pure enhance...

In our study, one-dimensional PbI₂/polyvinylpyrrolidone (PVP) composition fibers have been prepared by using PbI₂ and PVP as precursors dissolved in N,N-dimethylformamide via a electrospinning process. Dipping the fibers into CH₃NH₃I solution changed its color, indicating the formation of CH₃NH₃PbI₃, to obtain CH₃NH₃PbI₃/PVP composite fibers. The structure, morphology and composition of the all...

Ultra-flexible and transparent metal oxide transistors are developed by doping In2 O3 films with poly(vinylphenole) (PVP). By adjusting the In2 O3 :PVP weight ratio, crystallization is frustrated, and conducting pathways for efficient charge transport are maintained. In2 O3 :5%PVP-based transistors exhibit mobilities approaching 11 cm(2) V(-1) s(-1) before, and retain up to ca. 90% performance ...

Modified release formulations offer several advantages over conventional systems used in therapeutics. The aim of this work was to extend our previous studies on the chronobiotic hormone melatonin controlled release, by comparing its release from uncoated, compression-coated and bilayer tablets. Each tablet was comprised of melatonin and combinations of the following excipients: ethylcellulose,...

Photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. Although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...
