Development and optimization of a hydrogel with impregnated silver sulfadiazine was pursued, for antimicrobial topical applications. The selected hydrogel exhibited a homogeneous appearance, with whitish colloration and devoid of any fractures or cracks. The content in impregnated silver sulfadiazine was within established limits (1%, w/w) with a standard deviation of up to 1.28%. The hydrogel ...

BACKGROUND This study was conducted to compare the linear dimensional accuracy of die materials before and after disinfection of the impression. Type IV and V conventional dental stone, type IV-resin impregnated and copper-plated die materials were studied. MATERIALS AND METHODS A stainless-steel master die analogs to a complete veneer crown preparation with three scribed lines (I: vertical, ...

AIMS A fracture of the hip is the most common serious orthopaedic injury, and surgical site infection (SSI) is one of the most significant complications, resulting in increased mortality, prolonged hospital stay and often the need for further surgery. Our aim was to determine whether high dose dual antibiotic impregnated bone cement decreases the rate of infection. PATIENTS AND METHODS A quas...

Clinical scenario A rural hospital hires a new infection control professional, EL, who has just received her master’s degree and trained in infection control departments that were up to date on the best evidence. EL reviews the infection control policies and learns that traditional central line catheters are used. Where she trained, a new,more expensive, antiseptic catheter was used. The new ca...

A new deformation technique of wood flow forming is promising for industrial uses of solid wood. Flow deformability, size stability, and good mechanical properties were obtained by using wood impregnated with low molecular weight phenol formaldehyde (PF) resin. In this study, to clarify the effect of the PF resin and moisture contents in wood on the flow deformability (extrudability) and the me...

BACKGROUND Infection is one of the most devastating complications after primary total knee arthroplasty (TKA). Antibiotics-impregnated cement has been used and proven effective in preventing deep infection. This study was to evaluate the long-term results of using cefuroxime-impregnated cement and systemic cefazolin for one week to assess their efficacy in preventing infection of primary TKA. ...

introduction: this in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. methods and materials: fifty-six intact human premolars were chosen and randomly divided into four groups ( n =14). after preparation of a mesio-occluso-distal (mod) cavities and cusp reduction, the ...

This paper presents an investigation on the bond behavior of carbon fabric-cementitious matrix interface within fabric reinforced cementitious (FRCM) composite. The embedded yarn shows a complicated due to stochastic and incomplete impregnation can be subdivided into outer (impregnated) inner (non-impregnated) parts. Pullout tests were carried out FRCM composite aiming at examining effect betwe...

In this study, special ceramic grinding plates impregnated with diamond grit and other abrasives, as well self-made lapping plates, were used to prepare the surface of single-crystal silicon carbide (SiC) wafers. This novel approach enhanced process reduced final chemical mechanical planarization (CMP) polishing time. Two different pads mixed abrasives prepared: one self-modified + SiC a binder...

Its relatively low cost and high surface area makes activated carbon an ideal adsorbent candidate for H2S removal. However, physical adsorption of is not very effective; therefore, methods to facilitate reactive oxidation on carbons are interest. The performance removal non-impregnated, impregnated, doped in low-temperature syngas was evaluated fixed-bed breakthrough tests. importance oxygen co...
