BACKGROUND Osteoporotic vertebral compression fractures (OVCFs) are the most common osteoporotic fractures. Pain is the main symptom. Percutaneous vertebroplasty (PVP) is a therapeutic procedure performed to reduce pain in vertebral compression fractures. Numerous case series and several small, non-blinded, non-randomized controlled studies have suggested that vertebroplasty is an effective mea...

Accurately identifying bacteriophage virion proteins from uncharacterized sequences is important to understand interactions between the phage and its host bacteria in order to develop new antibacterial drugs. However, identification of such proteins using experimental techniques is expensive and often time consuming; hence, development of an efficient computational algorithm for the prediction ...

OBJECTIVES Poor solubility and toxicity severely hinder the clinical use of amphotericin B (AmB), in spite of its attractive chemotherapeutic properties. Water-soluble complexes of AmB and polyvinylpyrrolidone (AmB-PVP) could display lower cytotoxicity while maintaining antifungal activity. METHODS AmB-PVP [with PVP of 10, 24 and 40 kDa (AC1, AC2 and AC4)] were compared with free AmB for (i) ...

OBJECTIVE To determine whether biofilm formation on silicone tympanostomy tubes (TTs) is prevented by polyvinylpyrrolidone (PVP) coating. DESIGN In vitro microbiologic study. SUBJECTS Silicone TTs with and without a PVP coating. INTERVENTION The TTs were exposed to blood or phosphate-buffered saline and cultured with Pseudomonas aeruginosa or Staphylococcus aureus. After 4 days, antibioti...

OBJECTIVE Photoselective vaporization of the prostate (PVP) using GreenLight and Holmium laser enucleation of the prostate (HoLEP) is an important surgical technique for management of benign prostate hyperplasia (BPH). We aimed to compare the effectiveness and safety of PVP using a 120 W GreenLight laser with HoLEP in a small prostate volume. METHODS Patients who underwent PVP or HoLEP surger...

An implantable glucose microbiosensor that utilizes an electrodeposited redox polymer/glucose oxidase (GOX) sensing membrane and a highly hydrophilic poly (4-vinyl pyridine-co-acrylic acid) (PVP-PAC) overcoating as an analyte-regulating membrane has been developed. A gold microelectrode was electrodeposited with the redox polymer/GOX composite sensing membrane. Two polymers, a hydrophobic poly ...

STUDY DESIGN Retrospective study. OBJECTIVE To determine the malignancy rate and histology in bone biopsies obtained during PVP for VCF. SUMMARY OF BACKGROUND DATA Osteoporotic vertebral compression fractures (VCF) affect approximately 20% of postmenopausal women and can lead to long-term disability. Percutaneous vertebroplasty (PVP) is a minimally invasive procedure, primarily used in pati...

OBJECTIVES The aim of the study was to investigate the clearance of PVP-iodine applied as a gel or solution in periodontal pockets. METHODS Teeth of 12 subjects with at least eight periodontal pockets of �5 mm probing depth were isolated with a rubber dam to allow contamination-free access to the pockets. In each subject, three pockets were filled with PVP-iodine gel (10%) and three with PVPiod...

BACKGROUND Vertebral metastases are the most frequent vertebral tumor. Transarterial embolization (TAE) devascularizes the tumor, resulting in tumor necrosis. Percutaneous vertebroplasty (PVP), a minimally invasive procedure, can effectively relieve tumor-related pain and improve spine stability. Unfortunately, the PVP technique is of limited use in controlling the progression of vertebral tumo...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...
