in this study, a simple and reliable method by gas chromatograph–mass spectrometry (gc–ms) was developed for the fast and regular identification of 3, 4-mdma impurities in ecstasy tablets. in so doing, 8 samples of impurities were extracted by diethyl ether under alkaline condition and then analyzed by gc–ms. the results revealed high mdma levels ranging from 37.6% to 57.7%. the gc-ms method sh...

We estimate the effect of Vietnam era Army service on mortality, exploiting Australia’s conscription lotteries for identification. We utilise population data on deaths during 1994-2007 and military personnel records. The estimates are identified by over 51,000 compliers induced to enlist in the Army, including almost 16,000 who served in Vietnam. The implicit comparison group is the set of men ...

The present study is designed to evaluate the application of a simple method for rapid identification of Malassezia furfur among other Malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing L-tryptophan as a sigle source of nitrogen.  91 strains of Malassezia (20% M. furfur, 2% M. sympodialis, 5% M. obtosa and 73% M. globosa) isolated from ski...

Candida species are important nosocomial pathogens associated with high mortality rates. Rapid detection and identification of Candida species can guide a clinician at an early stage to prescribe antifungal drugs or to adjust empirical therapy when resistant species are isolated. Confocal Raman microspectroscopy is highly suitable for the rapid identification of Candida species, since Raman spe...

Precise identification of microorganisms involved in candidiasis together with antifungal susceptibility evaluation could help clinicians to prescribe appropriate medicine, especially in patients with critical conditions. The present study has been conducted to evaluate discriminatory power of Integral System Yeast Plus (ISYP) for rapid identification and determination of antifungal susceptibil...

Background and Purpose :Candidiasis is a widespread fungal infection caused by different Candida species. Rapid identification of Candida species in clinical laboratory is becoming increasingly important since the identification and discrimination of ethological agents for early treatment. We aimed at molecular identification of commonly Candida species isolated from clinical samples by using b...

New technologies enable us to build systems with greater complexity. To reduce risks imposed by the increasing complexity, organizations have to rely on seamless integrations and/or collaborations to build up their enterprises or improve their existing operations. Therefore, more and more companies that traditionally thought of themselves as system developers are beginning to realize that in fa...

AIMS A set of five tests were developed and tested for their ability to confirm the identity of C difficile colonies within 30 minutes. METHODS The relevant substrates were incorporated into four filter paper squares attached to a plastic carrier (Diffstrip), five enzymes/products (prolyl aminopeptidase, galactosidase, leucine aminopeptidase, acid phosphatase and indole). The strips were inoc...
