OBJECTIVES The purpose of this study was to investigate the effectiveness of multiple decontamination procedures for salivary contamination after curing of a universal adhesive on dentin bond strength according to its etch modes. MATERIALS AND METHODS Forty-two extracted bovine incisors were trimmed by exposing the labial dentin surfaces and embedded in cylindrical molds. A universal adhesive...

BACKGROUND The soil contaminated by depleted uranium (238U) ammunition during the NATO bombing of Serbia and Montenegro was cleaned-up for four months in 2002. A team of 11 clean-up workers (expert members) were medically examined three times: before decontamination as a preliminary medical check-up, immediately after decontamination, and four years after cleaning up contaminated ground. OBJE...

Highly toxic organophosphorus compounds (OPs) were originally developed for warfare or as agricultural pesticides. Today, OPs represent a serious threat to military personnel and civilians. This study investigates the in vivo decontamination of male Wistar rats percutaneously exposed to paraoxon and two potent nerve agents--soman (GD) and VX. Four commercial detergents were tested as decontamin...

The combination of pillarization and charge neutralization with Li+ can make montmorillonite an important support material for industry decontamination pollutants in soil water. Montmorillonite characterization techniques were described detail, procedures used, after saturation, to modify manipulate the chemical mineralogical surface properties this montmorillonite. Eight samples produced: 1) n...

Evidence to inform decontamination practices at Ebola holding units (EHUs) and treatment centres is lacking. We conducted an audit of decontamination procedures inside Connaught Hospital EHU in Freetown, Sierra Leone, by assessing environmental swab specimens for evidence of contamination with Ebola virus by RT-PCR. Swabs were collected following discharge of Ebola Virus Disease (EVD) patients ...

The binding specificity and affinity of aptamers have long been harnessed as the key elements in the development of aptamer-based assays, particularly aptasensing application. One promising avenue that is currently explored based on the specificity and affinity of aptamers is the application of aptamers in the decontamination assays. Aptamers have been successfully harnessed as the decontaminat...

Concerns have been raised regarding the availability of National Institute for Occupational Safety and Health (NIOSH)-certified N95 filtering facepiece respirators (FFRs) during an influenza pandemic. One possible strategy to mitigate a respirator shortage is to reuse FFRs following a biological decontamination process to render infectious material on the FFR inactive. However, little data exis...

UNLABELLED In accord with as-low-as-reasonably-achievable and good-manufacturing-practice concepts, the present study evaluated the efficiency of radioactivity decontamination of materials commonly used in laboratory surfaces and whether solvent spills on these materials affect the findings. METHODS Four materials were evaluated: stainless steel, a surface comprising one-third acrylic resin a...

BACKGROUND & OBJECTIVES There has been an extensive invasion of tuberculosis at the global level by multidrug resistant as well as extensively drug resistant organisms. Attempts to recover the pathogen in pure culture have frequently failed since the specimens are often highly contaminated and also due to use of insufficient or over-active decontamination procedures. Hence in the present study ...

BACKGROUND Duration of digestion/decontamination has a considerable impact on yield of mycobacteria especially from sterile body fluids and pus specimens. Additionally, duration of digestion/decontamination affects the contamination rates. This study evaluates the effect of digestion/decontamination protocol for 15 and 20min versus inoculation of media directly from the sample on contamination ...
