BACKGROUND Detection of latent tuberculosis infection (LTBI) in transplant candidates is very important. The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are standard immunologic tools for LTBI detection. The aim of this study was to compare the TST results and T-SPOT(®).TB test (a type of IGRAs) in kidney transplant candidates for the screening of LTBI and follow the ...
BACKGROUND The Beutler enzyme spot test is an effective assay for newborn mass screening of galactosemia, but it is qualitative and relies on visual interpretation. We describe a quantitative, instrumental modification of the assay. METHODS We modified the macroscopic visual Beutler enzyme spot test by adding extraction of blood components from filter paper, deproteinization with acetone-meth...
one of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. in particle simulations, the test particle method is usually used to get some idea of the behavior of plasma or other substances. in this method, first, a small number of particles are injected into the frame of static electromagnetic fields. then, ...
It is thought that the high protein density in the mitochondrial matrix results in severely restricted solute diffusion and metabolite channeling from one enzyme to another without free aqueous-phase diffusion. To test this hypothesis, we measured the diffusion of green fluorescent protein (GFP) expressed in the mitochondrial matrix of fibroblast, liver, skeletal muscle, and epithelial cell lin...
Abstract Background and objectives: Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway. G6PD deficiency (an X-linked recessive hereditary disease) is an inherited condition affecting approximately 3% of the people globally. This deficiency can cause hemolytic anemia and jaundice in neonates. The goal of this study is to detect the prevalence of G6PD deficienc...
1,3,5-trinitroperhydro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and pentaerythritol tetranitrate (PETN), the major components in plastic explosives, pose a significant threat to public safety. A quick, sensitive, and low-cost detection method for these non-volatile explosives is eagerly demanded. Here we present a fluo-spot approach, which can be employed fo...
The fluorescent treponemal antibody (FTA-200) test has been shown to detect at least two types of antibody in syphilitic serum; one of these, which can be removed by absorption with Reiter treponemes, is thought to be a group antibody which reacts with an antigen shared by Treponema pallidum and other treponemes (Deacon and Hunter, 1962). A second antibody, which remains after such an absorptio...
