PURPOSE To evaluate microbial contamination in silver-impregnated contact lens (CL) storage cases while establishing the effect of "wet " and "dry " case maintenance and to determine its association with clinical signs, symptoms, and compliance. METHODS Two noncontemporaneous prospective studies were conducted. Regular storage cases in study 1 (n = 40) and silver-impregnated cases in study 2 ...

Textile engineering can offer a multi-scale toolbox via various fiber or textile fabrication methods to obtain woven nonwoven aerogels with different structural and mechanical properties overcome the current limitations of polysaccharide-based aerogels, such as poor undeveloped shaping techniques. Hereby, high viscous solution microcrystalline cellulose zinc chloride hydrate was wet spun produc...

Lavender oil- (LO-) loaded ultrafine nanoparticles (NP) ( diameter < 50 nm ) of a copolymer were used for impregnating fabrics cotton, cotton polyester, and polyester-elastane. The was composed mainly methyl methacrylate (MMA) units with low proportion methacryli...

To assess the efficacy of antimicrobial-impregnated catheters in preventing catheter-related infections during external ventricular drainage (EVD), we performed a meta-analysis and systematic review. We systematically searched Medline, Embase, and the Cochrane Library. All randomized controlled trials (RCTs) and nonrandomized prospective studies (NPSs) related to antimicrobial-impregnated EVD c...

background: one approach for prevention of cutaneous leishmaniasis is creation of a barrier between the insect vector (phlebotomus) and the host.  many, but not all, researchers claim that permethrin-impregnated uniforms are effective for prevention of cutaneous leishmaniasis.  we determined the efficacy of permethrin-impregnated uniforms for prevention of cutaneous leishmaniasis among iranian ...

CONTEXT A recent randomized controlled trial and meta-analysis indicated that central venous catheters impregnated with an antiseptic combination of chlorhexidine and silver sulfadiazine are efficacious in reducing the incidence of catheter-related bloodstream infection (CR-BSI); however, the ultimate clinical and economic consequences of their use have not been formally evaluated. OBJECTIVE ...

Far infrared (FIR) radiation (λ = 3-100 μm) is a subdivision of the electromagnetic spectrum that has been investigated for biological effects. The goal of this review is to cover the use of a further sub-division (3- 12 μm) of this waveband, that has been observed in both in vitro and in vivo studies, to stimulate cells and tissue, and is considered a promising treatment modality for certain m...

PURPOSE The aim of this study was to compare the flexural strength of polymethyl methacrylate (PMMA) and bis-acryl composite resin reinforced with polyethylene and glass fibers. MATERIALS AND METHODS Three groups of rectangular test specimens (n = 15) of each of the two resin/fiber reinforcement were prepared for flexural strength test and unreinforced group served as the control. Specimens w...

A variety of therapeutic modalities, from implant to conventional Maryland prosthesis, can be used for the replacement of a missing anterior tooth. Whenever a minimal tooth reduction is preferred, a fiber reinforced composite (FRC) prosthesis could be a good alternative to conventional prosthetic techniques, chiefly as temporary restoration before making a final decision on the treatment. The p...
