We have investigated the expression of interleukin-3 receptor alpha (IL-3Ralpha) chain in primary blasts from 79 patients with acute myeloid leukemia (AML), 25 patients with B-acute lymphoid leukemia (B-ALL), and 7 patients with T-acute lymphoid leukemia (T-ALL) to evaluate a linkage between the expression of this receptor chain, blast proliferative status, and disease prognosis. Although IL-3R...

Immunoglobulin (Ig) is present on a large fraction of T cells from unfractionated lymphocytes activated by in vitro stimulation with H-2-incompatible cells (mixed lymphocyte reaction [MLR]). Removal of bursa equivalent-derived (B) cells from the responder cell population before mixed culture, by filtration through nylon wool columns, reduces the percentage of Ig-bearing responder T blasts to ba...

Disease relapse sometimes occurs after acute promyelocytic leukemia (APL) therapy with all-trans retinoic acid (ATRA). Among the diagnostic parameters predicting relapse, heterogeneity in the in vitro differentiation rate of blasts is an independent factor. To identify biologic networks involved in resistance, we conducted pharmacogenomic studies in APL blasts displaying distinct ATRA sensitivi...

Folylpolyglutamate synthetase (FPGS) is responsible for the metabolism of natural folates and a broad range of folate antagonists to polyglutamate derivatives. Recent studies indicated increased accumulation of methotrexate (MTX) polyglutamates (MTX-PG) in blast cells as a predictor of favorable treatment outcome in childhood acute lymphoblastic leukemia (ALL). We determined the expression of F...

Blast charge initiation procedures have a significant impact on both mining safety and production rates. In this study, the inventory benefit of an electric system was investigated to assess its influence fragmentation blast-induced damages. The WipFrag software used examine size distribution productivity 12 small-scale blasts initiated by nonelectric detonators. All blast rounds were with plai...

Neuro-immune interactions enable mutual regulation of the nervous and immune systems. To date, evidence exists for manipulations of immune cells by neurotransmitters in the periphery. In this study, we suggest the existence of a pathway by which the brain affects immune cells. The pathway we describe here is mediated by dopamine receptors expressed on activated T cells, termed blasts. Blasts ca...

Abstract We present our analysis of the detections from Piszkés-tető, Hungary infrasound array that has been operational since May 2017. introduce an automatic search method to associate with a preliminary list explosions detected by seismic network. Once are associated events, we relocate events using both arrival time and azimuth observations. validate methodology on ground truth i.e., confir...

background: induction chemotherapy for acute lymphoblastic leukemia achieves complete remis sion in over 90% of children. it is apparent therefore that many patients in clinical remission and with out residual disease detectable by conventional light microscopy of peripheral blood or bone marrow films still harbor viable cells of the original disease mrd analysis does have a useful role to play...
