Bcl-2 expression has been shown in hematopoietic progenitor cells. Through the use of Bcl-2 specific antisense oligonucleotides we herein report the biologic importance of Bcl-2 expression in primary human CD34+ hematopoietic progenitor cells committed to the myeloid lineage. In bone marrow or peripheral blood derived CD34+ cells Bcl-2 specific antisense(More)
Recent in vitro analyses of human UCB have demonstrated the potential of UCB as a source for haematopoietic stem and progenitor cell harvest. Clinical data have further indicated that UCB can be given in vivo to fully and partially HLA-matched siblings or non-familial recipients for marrow reconstitution in genetic disorders as well as malignancies. In(More)
Endothelin (ET)-1 is a potent vasoconstrictor peptide that is elevated in cardiovascular diseases. However, the biological function of ET-1 gene expression within arteries in vivo has not been determined. The effects of ET-1 gene expression were investigated using gene-transfer methods on porcine vascular cells in vitro and porcine arteries in vivo.(More)
It was not possible to synthesize beta-nicotinamide-alpha-adenine dinucleotide (NalphaAD) via the NAD pyrophosphorylase-catalyzed reaction of beta-nicotinamide mononucleotide and alpha-adenosine-5'-O-triphosphate. It was therefore prepared by reacting a mixture of beta-nicotinamide mononucleotide and alpha-adenosine-5'-O-monophosphate in aqueous pyridine,(More)
Histophagous scuticociliate infections were discovered in blue crabs, Callinectes sapidus, held in research facilities at the Virginia Institute of Marine Science. Ciliates were observed infecting every tissue examined including the gills, heart, muscle, hepatopancreas, and epidermis. Hemolymph smears and histological tissue sections indicated a(More)
We report on the chemical preparation of the NAD+ analog P1, P2-(5'-beta-nicotinamideribofuranosyl-3"-adenosyl)-diphosphate (N3"AD+) by applying the 1,1'-carbonyldiimidazole activation method. The importance of how adenosine is linked to the nicotinamide mononucleotide phosphoriboride (NMNPR+) moiety is discussed with respect to the coenzyme activity in the(More)
Monoclonal antibodies were used to determine the relationships between epitopes on the p55 chain of the IL-2 receptor and high-affinity IL-2 binding. Five monoclonal antibodies to the human P55 chain of the IL-2 receptor were induced by immunizing mice with murine L cells that were transfected with human p55 cDNA. Since the p55 chain is the only human(More)
Spectacular examples of cooperative behavior emerge among a variety of animals and may serve critical roles in fitness [1, 2]. However, the rules governing such behavior have been difficult to elucidate [2]. Drosophila larvae are known to socially aggregate [3, 4] and use vision, mechanosensation, and gustation to recognize each other [5-8]. We describe(More)
