Acute myeloid leukemia (AML) has distinct subgroups characterized by different maturation and specific chromosomal translocation. In order to gain insight into the gene expression activities in AML, we carried out a gene expression profiling study with 21 AML samples using cDNA microarrays, focusing on acute promyelocytic leukemia with specific translocation t(15;17)(q22;q12) [French-American-B...
Acute mixed myeloid-lymphoid leukemia is uncommon. We report four cases in which myeloid and lymphoid cell markers were observed simultaneously or sequentially when 94 patients with acute leukemia were phenotyped according to the French-American-British (FAB) classification system, with cytochemical stains, and with immunologically defined differentiation markers (identified by monoclonal antib...
Because of a lack of specific clonality markers, information on lineage involvement and cell of origin of acute myeloid leukemia with normal karyotype (AML-NK), is missing. Because Nucleophosmin (NPM) gene is frequently mutated in AML-NK and causes aberrant NPM cytoplasmic localization (NPMc+), it was used as an AML lineage clonality marker. Clonal NPM exon 12 mutations were detected in myeloid...
Intact sheep antidigoxin antibodies and their Fab fragments have both been found to exert profound effects on digoxin pharmacokinetics in [3H] digoxin-treated dogs. Both classes of molecule remove digoxin from the extravascular space and sequester it in the circulation in protein-bound form, a form in which the digoxin is presumably inactive. These two classes of molecule differ, however, in th...
Performance on the Frontal Assessment Battery is sensitive to frontal lobe damage in stroke patients
BACKGROUND The Frontal Assessment Battery (FAB) is a brief battery of six neuropsychological tasks designed to assess frontal lobe function at bedside [Neurology 55:1621-1626, 2000]. The six FAB tasks explore cognitive and behavioral domains that are thought to be under the control of the frontal lobes, most notably conceptualization and abstract reasoning, lexical verbal fluency and mental fle...
The myelodysplastic syndromes (MDS) are clonal hematopoietic diseases characterized by medullary dysplasia, cytopenias, and frequent evolution to acute myeloid leukemia. In 1982, the French-American-British (FAB) group proposed a classification for the MDS, based on morphological characteristics of peripheral blood and of the bone marrow. Later, cytogenetics proved to be a useful tool for the r...
Digitalis intoxication is a common and potentially life-threatening situation [1]. In this condition, the administration of digoxin-specific antibodies (Fab) have proven to be effective in controlling serious complications [2]. However, in patients with severe renal impairment, the clearance of Fab–digoxin complexes is compromised, and this may reduce the utility of Fab therapy in those conditi...
The aim of this research is to develop a human/murine chimeric Fab antibody which neutralizes the anthrax toxin, protective antigen (PA). The chimeric Fab was constructed using variable regions of murine anti-PA monoclonal antibody in combination with constant regions of human IgG. The chimeric PA6-Fab was expressed in E. coli. BL21 and evaluated by ELISA and co-immunoprecipitation- mass spectr...
UNLABELLED One mechanism of resistance to trastuzumab in human epidermal growth factor receptor-2 (HER2)-positive breast cancer (BC) is increased epidermal growth factor receptor (EGFR) expression. We have developed (111)In-labeled bispecific radioimmunoconjugates (bsRICs) that bind HER2 and EGFR on BC cells by linking trastuzumab Fab fragments through a polyethylene glycol (PEG24) spacer to ep...
Blast cell morphology was assessed at diagnosis and subsequent bone marrow relapse in 33 unselected patients with lymphoblastic leukemia (ALL). Each marrow was classified 'blind' according to the French-American-British (FAB) criteria, and it was found that 19 of 24 (79%) patients initially typed as FAB L1 changed to FAB L2 during the course of their disease, but no patient made the reverse mor...
