The low aqueous solubility of celecoxib (CB) and thus its low bioavailability is a problem. Thus, it is suggested to improve the solubility using cosolvency and solid dispersions techniques. Pure CB has solubility of 6.26±0.23μg/ml in water but increased solubility of CB was observed with increasing concentration of cosolvents like PEG 400, ethanol and propylene glycol. Highest solubility (791....

Herein, we report the development of a fluorescent material with temperature memory properties. Unlike previously developed systems which can only on single triggering point, conjugated polyelectrolyte-based sensor detects its exposure to wide range temperatures. To achieve this unique property, large poly(phenyl ethylene) (PPE-CO2) polyelectrolytes are destabilized and locked in more emissive ...

The development of thin-film composite membranes has gained more importance as they exhibit higher permeability, solute rejection and improved antifouling behavior. incorporation hydrophilic nanomaterials within the thin film reported to effectively increase hydrophilicity improve membrane performance. In this study novel nanofiltration were prepared by interfacial polymerization trimesoyl chlo...

Nutritive values of green and black tea by-products and anti-nutritive activity of their tannins were evaluated in an in vitro rumen fermentation using various molecular weights of polyethylene glycols (PEG), polyvinyl pyrrolidone (PVP) and polyvinyl polypyrrolidone as tannin-binding agents. Significant improvement in gas production by addition of PEG4000, 6000 and 20000 and PVP was observed on...

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit ⁄yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using va...

Postural control changes were studied in 27 patients with Parkinson's disease after unilateral posteroventral pallidotomy (PVP). Patients were evaluated before PVP and at 3, 6 and 12 months post-PVP, both 'off' and 'on' parkinsonian medications, with selected evaluation tools representing functional performance, functional balance and posturographic components of balance. The majority of variab...

OBJECTIVES The objective of this review is to provide an evidence-based update on laser surgery for BPH with a focus on comparing Greenlight Photoselective Vaporisation of the Prostate (PVP) to Holmium Laser Enucleation of the Prostate (HoLEP). METHODS We reviewed all HoLEP and PVP papers identified by a Pubmed search using the keywords: laser, prostate, BPH, holmium, HoLE, PVP and greenlight...

BACKGROUND AND PURPOSE The patient populations that are most likely to benefit from percutaneous vertebroplasty (PVP) are uncertain. Our purpose was to evaluate the effect of the age of vertebral compression fracture (VCF) on clinical improvement after PVP. METHODS We performed a retrospective review of charts of patients who had undergone PVP for painful osteoporotic VCFs at our institution....

OBJECTIVES To investigate whether the presence of detrusor overactivity (DO) influences storage symptoms after photoselective laser vaporization of the prostate (PVP) for benign prostatic hyperplasia (BPH). METHODS A total of 149 patients who underwent PVP were included in this retrospective study. All patients underwent a preoperative evaluation including multichannel video urodynamics. The ...

A dual network hydrogel made up of polyvinylalcohol (PVA) crosslinked by borax and polyvinylpyrrolidone (PVP) was prepared by means of freezing-thawing circles. Here PVP was incorporated by linking with PVA to form a network structure, while the introduction of borax played the role of crosslinking PVA chains to accelerate the formation of a dual network structure in PVA/PVP composite hydrogel,...
