BACKGROUND Percutaneous vertebroplasty (PVP) typically involves conventional lower-viscosity cement injection via bipedicular approach. Limited evidence is available comparing the clinical outcomes and complications in treating osteoporotic vertebral compression fractures (OVCFs) with PVP using high-viscosity cement through unipedicular or bipedicular approach. METHODS AND DESIGN Fifty patien...
This paper focuses on the significant properties of hydrogels prepared with polymeric biomaterials: solely biopolymers (gelatin (G) and sodium alginate (SA) as base polymer) or in combination with synthetic and bio polymers (polyvinylpyrrolidone (PVP) and carboxymethylcellulose (CMC)) for biomedical application. Four kinds of hydrogels: G/SA, G/SA/SB (without and with seabuckthron oil (SB)) and...
BACKGROUND/AIMS Povidone-iodine (PVP -I) is applied for microbial decontamination of human eyes donated for transplantation. Concentrations and immersion times vary greatly. The effectiveness and toxicity of PVP-I were assessed for different decontamination protocols. METHODS Human donor eyes and corneas were immersed in different concentrations (5-100 mg/ml) of PVP-I for different times (2-3...
Peripheral Venous Pressure Measurements in Patients With Acute Decompensated Heart Failure (PVP-HF).
BACKGROUND Accurate assessment of volume status is essential in diagnosis and guidance of decongestive therapy in patients with acute heart failure. We sought to compare peripheral venous pressure (PVP) with central venous pressure (CVP), as well as other invasive hemodynamic measurements, in patients hospitalized with an acute heart failure syndrome. METHODS AND RESULTS PVP-HF (Peripheral Ve...
OBJECTIVES This study aims to evaluate the size-dependent toxicity of spherical silver nanoparticles (Ag NPs) to an endemic benthic organism, Glyptotendipes tokunagai. METHODS Ag nanoparticles of three nominal sizes (50, 100, and 150 nm) capped with polyvinyl pyrrolidone (PVP-Ag NPs) were used. Their physicochemical properties, acute toxicity (48 hours), and bioaccumulation were measured usin...
Interpolymer complex formation of polyvinylpyrrolidone (PVP) with carboxyvinyl polymer (CP) was examined by turbidity measurement, a binding isotherm study and Fourier-transform infrared spectroscopy. The interpolymer complex of PVP with CP was found to be formed in the unit molecular ratio of 1: 1 under ideal conditions, though the ratio of PVP in the solid complex was lower than 1: 1 under pr...
BACKGROUND Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) could give rise to excellent outcomes and significant improvements in pain, analgesic requirements, function, cost, and incidence of serious complications for thoracolumbar osteoporotic vertebral compression fractures (VCFs). But some studies showed the recurrent fracture of a previously operated vertebra or adjacen...
PURPOSE To compare photoselective vaporization of the prostate (PVP) using the 120W GreenLight™ laser with transurethral resection of the prostate (TURP) in terms of their cost to the Greek National Health Service (NHS) or to the Public Insurance Sickness Funds (PISF). PATIENTS AND METHODS A prospective cost evaluation with 1-year follow-up of 60 patients with infravesical obstruction of beni...
Percutaneous vertebroplasty (PVP) has been used to relieve pain and to prevent further collapse of the vertebral body in patients with an osteoporotic compression fracture. The most commonly affected site for the use of PVP is the thoracolumbar junction. There are few reports that have described on the usefulness of PVP in the treatment of a high thoracic compression fracture. We report a case ...
Type 2 antigens such as polyvinylpyrrolidone (PVP), 1 type III pneumococcal polysaccharide ($3), and dinitrophenyl (DNP)-ficoll characteristically elicit antibody responses in mice that consist almost entirely of antibodies of the IgM and IgG3 isotypes (1-4). Type 2 antigens also are generally unable to prime mice to produce I gG 1 and IgG2 antibodies after secondary challenge, i.e. they are un...
