Attention has been increasing focused on the role of the bone marrow microenvironment in the pathogenesis and progression of hematological malignancies, including myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).1–3 Thus, the identification of genes or proteins that are differentially expressed in the abnormal bone marrow niche may provide new therapeutic opportunities and persp...
Knowledge of the blast phenotype in myelodysplastic syndromes (MDS) would be valuable, as in other malignancies, but remains sparse. This is mainly because MDS blasts are a minor population in clinical samples, making analysis difficult. Thus, for this blast phenotype study, we prepared blast-rich specimens (using a new density-centrifugation reagent for harvesting blasts) from blood and marrow...
Riemerella anatipestifer is an important pathogenic bacterium that infects ducks. It exhibits resistance to multiple classes of antibiotics. Multidrug efflux pumps play a major role as a mechanism of antimicrobial resistance in Gram-negative pathogens and they are poorly understood in R. anatipestifer. In this study, a gene encoding the B739_0873 protein in R. anatipestifer CH-1, which belongs ...
Thrombocytopenia is a common, often fatal complication experienced by patients with myelodysplastic syndromes (MDS). 5-aza-2'-deoxycytidine (decitabine) has been used to treat MDS patients with thrombocytopenia with a response rate of 45-50%. However, the mechanism of its effects on megakaryocytes remains unclear. In the present study, the effect of decitabine on megakaryocyte maturation was in...
Treatment with erythropoietin (epo) may improve the anemia of myelodysplastic syndromes (MDS) in approximately 20% of patients. Previous studies have suggested that treatment with the combination of granulocyte colony-stimulating factor (G-CSF) and epo may increase this response rate. In the present phase II study, patients with MDS and anemia were randomized to treatment with G-CSF + epo accor...
INTRODUCTION The aim of this study was to analyse the clinico-pathological features of a cohort of patients with myelodysplastic syndromes (MDS). MATERIALS AND METHODS The clinical and pathological data of 43 MDS patients over a 3-year period were reviewed. Survival analysis was performed according to the French-American-British (FAB) classification and International Prognostic Scoring System...

The World Health Organization (WHO) classification contributes to refined classification and prognostication of myelodysplastic syndromes (MDSs). Flow cytometry might add significantly to diagnostic and prognostic criteria. Our analysis of bone marrow samples from 50 patients with MDS showed aberrant expression of differentiation antigens in the myelomonocytic lineage. This also accounted for r...
It has been unclear whether regimens containing topotecan 1 ara-C (TA) or fludarabine 1 ara-C (FA) 6 idarubicin are superior to regimens containing idarubicin 1 ara-C (IA) without either fludarabine or topotecan for treatment of newly diagnosed acute myeloid leukemia (AML), refractory anemia with excess blasts in transformation (RAEB-t), or RAEB. Of 1279 patients treated here for these diagnose...
