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...

OBJECTIVES To evaluate the capability of accident and emergency (A&E) departments in six health regions of England to safely decontaminate casualties exposed to hazardous chemicals. METHODS In January 1999 a postal questionnaire was sent to the clinical director of all A&E departments in Trent, North and South Thames, South and West, North West and, Anglia and Oxford Health Regions. The quest...

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 ...

All of the costs associated with decontamination following the 2001 anthrax letter attacks were summarized, estimated, and aggregated based on existing literature and news media reports. A comprehensive list of all affected structures was compiled. Costs were analyzed by building class and decontamination type. Sampling costs and costs of worker relocation were also included. Our analysis indic...

Shoe soles are possible vectors for infectious diseases. Although studies have been performed to assess the prevalence of infectious pathogens on shoe soles and decontamination techniques, no systematic review has ever occurred. The aim of this study was to perform a systematic review of the literature to determine the prevalence of infectious agents on shoe bottoms and possible decontamination...

OBJECTIVE We examined the impact of selective decontamination of the digestive tract on morbidity and mortality in critically ill children. DATA SOURCES We searched MEDLINE, EMBASE, the Cochrane Register of Controlled Trials, and previous meta-analyses. STUDY SELECTION We included all randomized controlled trials comparing administration of enteral antimicrobials in selective decontaminatio...

A yeast isolate revealing unique enzymatic activities and substrate-dependent polymorphism was obtained from autochthonous microflora of soil heavily polluted with oily slurries. By means of standard yeast identification procedures the strain was identified as Trichosporon cutaneum. Further molecular PCR product analyses of ribosomal DNA confirmed the identity of the isolate with the genus Tric...
