BACKGROUND As an alternative to transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP) provides a bloodless, relatively painless relief of lower urinary tract symptoms for men with benign prostatic hyperplasia. Following a review of the evidence in 2006, the Ontario Health Technology Advisory Committee recommended that a study be conducted to evaluate ...

Polyvinylidene fluoride/polyvinylpyrrolidone (PVDF/PVP) hollow fiber membranes were fabricated by dry-jet wet-spinning process. The correlated effects of the air gap length and PVP concentration ((1) the air gap length effect at the low and high PVP concentration in the dope solutions, as well as (2) the effect of the PVP concentration at the same air gap length) on the cross-section structure ...

BACKGROUND Clinically, percutaneous vertebroplasty (PVP) is frequently applied to treat osteoporotic vertebral compression fracture (OVCF). It is believed that new compression fractures are more likely to occur adjacent to the PVP-treated segment, typically within 1 month after PVP. The purpose of this study was to investigate risk factors for adjacent vertebral compression fractures (AVCF) aft...

BACKGROUND Recently percutaneous vertebroplasty (PVP) was frequently performed for treatment of osteoporotic vertebral fractures (VFs). It is widely accepted that new compression fractures tend to occur adjacent to the vertebral bodies, typically within a month after PVP. To determine the risk factors among several potential predictors for de novo VFs following PVP in patients with osteoporosis...

This study investigated the hemodynamic properties of the plantar venous plexus (PVP), a peripheral venous pump in the human foot, with Doppler ultrasound. We investigated how different ways of introducing mechanical changes vary in effectiveness of displacing blood volume from the PVP. The contribution of the PVP was analyzed during both natural and device-elicited compressions. Natural compre...

BACKGROUND AND OBJECTIVES To assess the influence of risk factors on the rates and kinetics of peripheral vein phlebitis (PVP) development and its theoretical influence in absolute PVP reduction after catheter replacement. METHODS All peripheral short intravenous catheters inserted during one month were included (1201 catheters and 967 patients). PVP risk factors were assessed by a Cox propor...

In conscious rats with near-malignant phases of DOCA-salt (DS) hypertension, hemodynamics were studied with microspheres before and after administration of a vasopressin (VP) vasopressor antagonist in relation to plasma VP levels (pVP). Compared to the controls, the DS rats showed significant elevations in mean arterial pressure (MAP), total vascular resistance (TVR), and pVP, and a flow redist...

Zinc ferrite nanocrystals were prepared from an aqueous solution containing metal nitrates and various of concentrations of poly(vinyl pyrrolidone) (PVP), i.e., 0, 15, 40, and 55 g/L, as a capping agent. To stabilize the particles, they were thermally treated at 873 K, as an optimum calcination temperature. The behaviors of the polymeric precursor were analyzed by use of simultaneous thermo-gra...

Intravenous infusion of 500 ml of 6% polyvinylpyrrolidone (PVP, average molecular weight 40,000) in isotonic saline solution daily for 2 days induced prompt and significant reductions in serum cholesterol and triglyceride concentrations in eight hyperlipidemic patients. Mean maximal decrements in serum cholesterol and triglyceride were 29% and 28% below control values, respectively, occurring 5...
