To reduce the workload and misjudgment of manually discriminating microseismic events blasts in mines, an artificial intelligence model called PSO-ELM, based on extreme learning machine (ELM) optimized by particle swarm optimization (PSO) algorithm, was applied this study. Firstly, difference between mine previous research results, 22 seismic parameters were selected as discrimination feature t...
Blood or bone marrow specimens from 22 patients with chronic myelogenous leukemia in blast crisis were studied for the surface expression of glycophorin-A, a marker for early erythroid differentiation. The leukemic blasts were stained with rabbit anti-glycophorin-A antiserum. The glycophorin-A molecules detected by the rabbit antiserum were identified by polyacrylamide slab gel electrophoresis ...
A simple underwater noise model suitable for use with explosives in the decommissioning of oil and gas subsea structures is introduced evaluated against data from five projects US. The performance compared to four existing models open water blasts, severance well conductors piles. Simulated received sound pressure levels were significantly correlated measurements all scenarios. maximum total er...
Early response to chemotherapy has a major prognostic impact in acute myeloid leukemia patients treated with a double induction strategy. Less is known about patients treated with standard-dose cytarabine and anthracycline. We designed a risk-adapted remission induction regimen in which a second course of intermediate-dose cytarabine was delivered after standard "7+3" only if patients had 5% or...
Mice with severe combined immunodeficiency (SCID) were injected intravenously with primary bone marrow blasts from 12 children with newly diagnosed t(4;11)(q21;q23) acute lymphoblastic leukemia (ALL). Blasts from eight patients caused overt disseminated leukemia, whereas blasts from the other four patients produced occult leukemia that was detectable only by the polymerase chain reaction (PCR) ...
Human T-cell blasts were generated by stimulation with mitogens and antigens. A proportion of these blasts expressed Ia antigens detectable by immunofluorescence with both allo- and hetero-antiserums. The maximal expression of Ia antigens was delayed and usually occurred after the peak of blastogenesis. Among the three mitogens used, pokeweed mitogen (PWM) was most effective in giving a high pe...
Diagnosis should always be based on a surgical specimen/ excisional lymph node biopsy. Core biopsies should only be performed in patients without easily accessable lymph nodes (e.g. retroperitoneal bulk). Fine needle aspirations are inappropriate for a reliable diagnosis. The histological report should give the diagnosis according to the WHO classification. Grading is performed according to the...
To establish the basis for the reduced expression of the X determinant on leukemic blasts and the changes in antigenic expression that occur during myeloid maturation, the presence on myeloid cells of X and related structures was examined in conjunction with studies on the activities of the glycosyltransferases involved in their biosynthesis. Expression of X and sialyl-X was weak on blasts in c...
Resting B cells enlarge, enter the cell cycle, and change their surface phenotype when activated via the surface immunoglobulin (Ig) receptor, but subsequent cell growth and antibody production is relatively limited. To identify stimuli that might prime B cells for enhanced function in vitro, we have compared the effects of anti-Ig with helper T (Th) cells on the formation of B lymphoblasts and...
