The purpose was to assess the elimination of Enterococcus faecalis in vitro in human mandibular premolars after chemomechanical preparation with or without the use of a calcium hydroxide dressing. After 60 days of contamination with E. faecalis, the root canals were prepared using the Crown-Down technique combined with 2% chlorhexidine gel irrigation. Then, the specimens were divided into two e...

While surgical site preparation has been extensively studied, there is little information about resistance of skin microbiota in the biofilm form to antimicrobial decontamination, and there are no quantitative models to study how biofilm might be transferred into sterile tissue/implant materials during injections for joint spine and tendon, aspiration biopsies and dermal fillers (DF). In this w...

imaging of infection and inflammation is an important issue in nuclear medicine as it may have relevant implication for the management of patients with infections or inflammatory diseases. in this regard the synthesis of human polyclonal immunoglobuline g (igg) radiolabeled with technetium-99m (99mtc) by a novel method, via a nicotinamide hydrazine derivative, was performed. the biological beha...

Low temperature vacuum drying is an alternative to sterile dry filling as a formulation approach for certain ethanol soluble substances that are poorly soluble or unstable in aqueous media. To date this ap­ proach has been limited to formulations containing the drug per se. However, several substances appear suitable as excipients in­ cluding urea, polyethylene glycol 4000, ascorbic acid, methy...

Non-sterile gloves are just as effective as sterile gloves in preventing surgical site infection after minor skin surgeries.
