Background: Salmonella is one of the most common food-borne pathogens that can cause illness. In this study, the sensitivity and the specificity of Aptamer-Magnetic bead Separation-Polymerase Chain Reaction (AMS-PCR) method were determined for Salmonella spp. detection. Methods: Different concentrations of Salmonella enterica were mixed with streptavidin-magnetic beads coated with biotinylated...

background: the objective of this study was to determine the diagnostic value of magnetic resonance imaging for shoulder joint pathologies and then compare the results with arthroscopy, the standard for joint diagnosis. methods: in this cross-sectional study, 80 patients with shoulder joint disorders, who underwent final arthroscopy, were studied. based on patients’ medical history and physical...

BACKGROUND AND OBJECTIVES This study was conducted by the International Consortium for Blood Safety (ICBS) to identify high-quality test kits for detection of hepatitis B virus (HBV) surface antigen (HBsAg) for the benefit of developing countries. MATERIALS AND METHODS The 70 HBsAg test kits from around the world were evaluated comparatively for their clinical sensitivity, analytical sensitiv...

When analysts are faced with the decision of selecting either mid-IR (MIR) or near-IR (NIR) spectroscopy for materials characterization, the decision is usually based on the analytical, sampling, and/ or operational needs. For example, when the greatest analytical specificity is required or certain inorganic materials need to be measured, the choice favors MIR; whereas the need to keep an unsta...

The critical role of energy consumption in biological systems including T cell discrimination process has been investigated various ways. kinetic proofreading(KPR) recognition involving different levels dissipation influences functional outcomes such as error rates and specificity. In this work, we study quantitatively how the cost fractions, sensitivity, specificity, speed terms Mean First Pas...

trichomoniasis is a worldwide infection and due to its complications rapid and accurate diagnosis of infection especially in pregnant women is very important. in this study, development of a latex agglutination test using native antigens for rapid diagnosis of trichomoniasis is investigated. trichomonas vaginalis was harvested from tyis33 culture medium and anti trichomonas vaginalis antiserum ...

the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...
