The AML-1/CBF beta transcription factor complex is targeted by both the t(8;21) and the inv(16) chromosomal alterations, which are frequently observed in acute myelogenous leukemia. AML-1 is a site-specific DNA-binding protein that recognizes the enhancer core motif TGTGGT. The t(8;21) translocation fuses the first 177 amino acids of AML-1 to MTG8 (also known as ETO), generating a chimeric prot...

patients with acute myeloblastic leukemia (aml) with monosomy 7 are a group of patients with refractory aml who have a very poor prognosis. therefore, rationally designed new therapies, including metronomic chemotherapy regimen with histidine deacetylase inhibitors (valporic acid, atra) are being investigated as potential treatments for the population of refractory cases of aml. herein, we repo...

Partially purified extracts from 33 human tumors of several histologic types were used as competing antigens in a radioimmunoassay for the p30 protein of an endogenous primate type C virus (M7). Antigens immunologically related to the p30 protein of the M7 virus were detected in two tumors. Like viral p30 antigens previously identified in tissues of several other primates, the antigens found in...

The effect of mixtures of antioxidants butylated hydroxyanisol (BHA) and propyl paraben (PP) on lag phase, growth rate and ochratoxin A (OTA) production by four Aspergillus section Nigri strains was evaluated on peanut meal extract agar (PMEA) under different water activities (a(w)). The antioxidant mixtures used were: BHA + PP (mM), M1 (0.5 + 0.5), M2 (1.0 + 0.5), M3 (2.5 + 0.5), M4 (0.5 + 1.0...

We have combined 2MASS and POSS II data in a search for nearby ultracool (later than M6.5) dwarfs with Ks < 12. Spectroscopic follow-up observations identify 53 M7 to M9.5 dwarfs and seven L dwarfs. The observed space density is 0.0045 ± 0.0008 M8-M9.5 dwarfs per cubic parsec, without accounting for biases, consistent with a mass function that is smooth across the stellar/substellar limit. We s...

abstract background leukemia is one of the most common tumors in children and it is divided up into two main groups acute and chronic leukemia. the acute leukemia is more prevalent than chronic in children. generally acute type is included acute lymphoid leukemia (all) and acute myeloid leukemia (aml). in this study, patients with leukemia who were admitted in talghani hospital of gorgan were e...

Therapy-related acute myeloid leukemia (t-AML) is a heterogeneous entity most frequently related to breast cancer or lymphoproliferative diseases (LD). Population-based studies have reported an increased risk of t-AML after treatment of lymphomas. The aim of this study was to describe the characteristics and outcome of 80 consecutive cases of t-AML following treatment of LD. t-AML accounted for...

The World Health Organization classification of acute myeloid leukemia (AML) is hierarchically structured and integrates genetics, data on patients' history, and multilineage dysplasia (MLD). The category "AML with myelodysplastic syndrome (MDS)-related changes" (AML-MRC) is separated from "AML not otherwise specified" (AML-NOS) by presence of MLD, MDS-related cytogenetics, or history of MDS or...

Let A be a fixed ring, and consider the projective space PA = ProjA[x0, . . . , xn] over A. On PA we have the invertible sheaf O(1), and the homogenous coordinates x0, . . . , xn give rise to global sections ẋ0, . . . , ẋn ∈ Γ(PA,O(1)). Throughout this section we drop the dot in this notation and just write xi for the global section of O(1). One sees easily that the sheaf O(1) is generated by t...

Dear Editor, The WHO 2008 classification of myeloid neoplasms lists the following three diagnostic criteria for AML with myelodysplasia-related changes (MRC): AML arising from a previously diagnosed myelodysplastic syndrome (MDS) or MDS/myeloproliferative neoplasm (MPN), AML with an MDS-related cytogenetic abnormality, and AML with multi-lineage dysplasia [1]. However, a history of Philadelphia...
