A novel cell line was established from a patient with a leukemic-state nasal angiocentric natural killer (NK) cell lymphoma with systemic skin infiltration. The morphology of the leukemic cells was large-granular-lymphocyte (LGL), and their immunophenotype was CD2+, CD3-, CD5+, CD7+, CD16-, CD56+, and CD57-. The presence of Epstein-Barr viral (EBV) genome was shown in specimens from the patient...

Our main interest in this paper is approximation of a continuous function, on a finite interval, which changes convexity finitely many times by algebraic polynomials which are coconvex with it. This topic has received much attention in recent years, and the purpose of this paper is to give final answers to open questions concerning the validity of Jackson type estimates involving the weighted D...

The crystallization behavior of a glass with the composition 54.7 SiO2·10.9 Al2O3·15.0 MgO·3.4 ZrO2·16.0 Y2O3 is studied using X-ray diffraction (XRD), scanning electron microscopy (SEM) including electron backscatter diffraction (EBSD) and (scanning) transmission electron microscopy [(S)TEM] including energy-dispersive X-ray spectrometry (EDXS). This glass shows the sole surface crystallizatio...

The extra-embryonic yolk sac (YS) is the first hematopoietic site in the mouse embryo and is thought to generate only primitive erythroid and myeloerythroid progenitor cells before definitive HSC emergence within the embryo on E10.5. Here, we have shown the existence of T cell-restricted progenitors in the E9.5 YS that directly engraft in recipient immunodeficient mice. T-cell progenitors were ...

Adaptive immunity and T cell function are affected by aging. Calcium influx patterns, regulated by Kv1.3 and IKCa1 potassium channels, influence T cell activation. We aimed to compare calcium influx kinetics in CD8, Th1 and Th2 cells in human peripheral blood samples obtained from five different age groups (cord blood, 10-15 ys, 25-40 ys, 45-55 ys, 60-75 ys).We measured calcium influx using flo...

In this paper, the influence of tempering temperatures on microstructures and tensile properties a Cr-N alloyed medium Mn martensitic steel was studied. The formed after below 400 °C are composed recovered martensite as matrix, ultrafine retained austenite (RA) carbonitrides. at 100 led to best combination 2080 MPa ultrahigh ultimate strength (UTS) 15% total elongation (TE), which is attributed...

Yield under water stress (YS) is used as the main criterion in the selection of wheat varieties for dry Mediterranean environments. It has been proposed that selection of genotypes using YS assisted by morphological and physiological traits associated with YS is more efficient in selecting high yielding genotypes for dry environments. A study was carried out at the Antumapu Experiment Station o...

a breeding hexaploid salt tolerant wheat line (ms-81-14) was produced from crossing of an iranian salt tolerant wheat line (1-66-22) with inia cultivar (from cimmyt) at karaj research station in 1991-92 cropping season. the f1 plants were grown at karaj in 1992-93 cropping season, furthermore f2-f6 populations were evaluated under salinity stress conditions (ecsoil&water; = 8-12 ds/m) in isfaha...
