OBJECTIVES Vancomycin and fosfomycin are antibiotics commonly used to treat methicillin-resistant Staphylococcus aureus (MRSA) infection. This study compares the in vitro inhibitory effects against MRSA of articulating cement spacers impregnated with either vancomycin or fosfomycin. METHODS Vancomycin-impregnated articulating cement spacers and fosfomycin-impregnated articulating cement space...

Toxic and feeding inhibition effect of cyfluthrin treated nets was assessed and compared with the activity of deltamethrin impregnated nets, before and after 2 and 4 washes against Phlebotomus papatasi. Impregnated cyfluthrin nets (50, 25, 12.5 mg active ingredient (a.i.)/m2) caused knock down and mortality rates higher than 90%, being of 100% at the highest dose, while the nets impregnated wit...

BACKGROUND According to early clinical trials, vascular brachytherapy performed prior to or shortly after angioplasty is very effective in reducing restenosis rates. The purpose of this study was to investigate the effects of a novel radioactive catheter that allows simultaneous balloon angioplasty and beta-particle irradiation in the prevention of restenosis. MATERIAL AND METHODS The balloon...

In cartilage tissue engineering from mesenchymal stem cells, it is important to suppress hypertrophy to produce a neocartilage with stable phenotypes of hyaline articular cartilage (AC). The aim of this study was to develop and test the usefulness of functional chondrogenic scaffolds that serve the purpose of hypertrophy suppression. PD98059-impregnated poly(lactic-co-glycolic acid) (PLGA) scaf...

We aimed to develop a high-throughput screening (HTS) system for preliminary predictions of human skin permeability by using an artificial membrane that can mimic the permeation behaviour of lipophilic and hydrophilic compounds across the human skin. In this study, we synthesized a copolymer containing poly(dimethylsiloxane) (PDMS) and poly(ethylene glycol) (PEG) 6000 and impregnated it onto a ...

Adsorption is a chemical method for water purification. In the present study, native and impregnated active carbon was used for adsorption to evaluate the efficacy of the process in manganese removal from aqueous solutions. Impregnation reaction was performed using the precipitate colloids of manganese oxides onto the carbon surface. X-ray diffraction, Fourier-transform infrared spectroscopy, a...

BACKGROUND/AIM Ventriculoperitoneal shunt infections remain an important problem and result mainlyfrom perioperative colonization of shunt components by skin flora. Antibiotic-impregnated shunts have been designed to prevent such colonization. T'his study evaluates the incidence of shunt infection after the insertion of antibiotic-impregnated shunts in a population of children with hydrocephalu...

In this study two solid supports, silica and florisil, were impregnated with crown ether (dibenzo-18-crown-6) and Fe(III) ions and their efficiency was compared in the adsorption process of As(V) from aqueous solutions. The solid supports were impregnated with crown ether due to their ability to build complexes with positives ions. Fe(III) was used because of As(V) affinity for it. The impregna...

The aim of this study was to determine the effectiveness of antibiotic-impregnated implants in the prevention of bone infection. We used a model of contaminated fracture in goats to evaluate four treatment groups: no treatment, hand-made tobramycin-impregnated polymethylmethacrylate beads, commercially-available tobramycin-impregnated calcium sulphate pellets and commercially-available tobramyc...

Controversy surrounds the role of central venous catheters (CVCs) impregnated with antimicrobial agents in the prevention of catheter-related bloodstream infection (CRBSI). We reviewed the current literature to evaluate the efficacy of antimicrobial-impregnated CVCs for preventing CRBSI. Eleven randomized studies published in article form were identified that included a control group that recei...
