The diagnostic value of a PCR assay that amplifies a 501-bp fragment of the Yersinia pestis caf1 gene has been determined in a reference laboratory with 218 bubo aspirates collected from patients with clinically suspected plague managed in a regional hospital in Madagascar. The culture of Y. pestis and the detection of the F1 antigen (Ag) by enzyme-linked immunosorbent assay (ELISA) were used a...
Using the chemical reduction method, silver nanoparticles (Ag NPs) were effectively synthesized into the zeolite framework in the absence of any heat treatment. Zeolite, silver nitrate, and sodium borohydride were used as an inorganic solid support, a silver precursor, and a chemical reduction agent, respectively. Silver ions were introduced into the porous zeolite lattice by an ion-exchange pa...
We have identified fifty-eight samples that were positive for Dengue-4 among 119 samples with negative diagnoses for dengue via the Platelia™ dengue NS1 Ag in Aracaju, State of Sergipe, Brazil. We determined that the low sensitivity of the NS1 Ag test could be related to secondary dengue infections in the studied population. Therefore, we concluded that the sensitivity and specificity of the Pl...
The heat of fusion and the specific heats of the solid and liquid have been experimentally determined for a Ti6&r4a alloy. The data are used to evaluate the Gibbs free energy difference, AG, between the liquid and the 0 phase as a function of temperature to verify a reported spontaneous vitrification (SV) of the fi phase in Ti-Cr alloys. The results show that SV of an undistorted fl phase in th...
Over decades the Ag 3d-level binding energy has been puzzling researchers with its unusual sign and value in silver oxides. For absolute majority of metals, metal-to-oxide shifts are positive depend significantly on oxidation state, while Ag-oxides oxide shift was time after reported negative, small, close for two very different Ag(I) Ag(III) states. In current work, a photoelectron spectroscop...
Antigen (Ag) immunization induces formation of the germinal center (GC), with large, rapidly proliferating centroblasts in the dark zone, and small, nondividing centrocytes in the light zone. We identified a novel nuclear protein, GANP, that is up-regulated in centrocytes. We found that GANP was up-regulated in GC B cells of Peyer's patches in normal mice and in spleens from Ag-immunized mice. ...
Introduction: Viral hepatitis is one of the causes of premature death in world peoples, according to WHO reports, five percentage of people are carrier, lethal from this disease is 1%, therefore about 1-1.5 million people each year die from complications of this disease. This disease varies from an acute to chronic illness. The aim of this study was to determine the level of anti-HBs Ag (hepati...
Somatic gain-of-function mutations in isocitrate dehydrogenases (IDH) 1 and 2 are found in multiple hematologic and solid tumors, leading to accumulation of the oncometabolite (R)-2-hydroxyglutarate (2HG). 2HG competitively inhibits α-ketoglutarate-dependent dioxygenases, including histone demethylases and methylcytosine dioxygenases of the TET family, causing epigenetic dysregulation and a blo...
TCRand chains are composed of somatically rearranged V, D, and J germline-encoded gene segments that confer Ag specificity. Recent crystallographic analyses revealed that TCRhas more contacts with peptide than TCR, suggesting the possibility that peptide recognition predominantly relies on TCR. T cells specific for the self Ag Melan-A/MART-1 possess an exceptionally high precursor frequency in ...
The response time of thermal electrolytic Ag/AgCl reference electrodes is defined by the porous structure that limits the rate at which traces of any previous solution are diluted by any new solution environment. The electrode stabilisation time when transferred from one electrolyte to another has been shown to change when different structural designs to the conventional sphere of Ag/AgCl are u...
