The Transfer Origin for Bacteroides Mobilizable Transposon Tn4555 Is Related to a Plasmid Family from Gram-Positive Bacteria
(East Carolina University, 1998-01)Conjugal transfer of Bacteroides mobilizable transposon Tn4555 was examined with an Escherichia coli-based assay system. It was shown that mobilization required the cis-acting oriTTn region and that the Tn4555 mobATn gene ... -
Life History Aspects of the Hickory Shad (Alosa Mediocris) in the Albemarle Sound/ Roanoke River Watershed, North Carolina
(East Carolina University, 1998-01)The hickory shad (Alosa mediocris), which supports commercial and recreational fisheries in the Roanoke River and Albemarle Sound, North Carolina, is an anadromous species closely related to the American shad (A. sapidissima). ... -
Cerebral Ischemia/Reperfusion Increases Endothelial Nitric Oxide Synthase Levels by An Indomethacin-Sensitive Mechanism
(1998-01-01)In anesthetized piglets, endothelial and neuronal nitric oxide synthase (eNOS and nNOS, respectively) levels were investigated after global cerebral ischemia. Increased intracranial pressure was used to produce 5 or 10 ... -
Identification and Characterization of alcR, a Gene Encoding an AraC-Like Regulator of Alcaligin Siderophore Biosynthesis and Transport in Bordetella pertussis and Bordetella bronchiseptica
(East Carolina University, 1998-02)A Bordetella bronchiseptica iron transport mutant was isolated following an enrichment procedure based on streptonigrin resistance. The mutant displayed a growth defect on iron-restricted medium containing ferric alcaligin ... -
Transcriptional Analysis of the Bordetella Alcaligin Siderophore Biosynthesis Operon
(East Carolina University, 1998-02)The alc gene cluster of Bordetella pertussis includes three genes, alcA, alcB, and alcC, which are involved in alcaligin siderophore biosynthesis in response to iron starvation. The production of AlcA, AlcB, and AlcC in ... -

Characterization of proteins binding the 3′ regulatory region of the IL-3 gene in IL-3-dependent and autocrine-transformed hematopoietic cells
(1998-03-08)Previously we documented the prolongation of the IL-3 mRNA half-life in an autocrine-transformed cell line. This cell line has an intracisternal type A particle transposition in the IL-3 mRNA 3′ untranslated region which ... -
Cloning and Characterization of the Pseudomonas aeruginosa zwf Gene Encoding Glucose-6-Phosphate Dehydrogenase, an Enzyme Important in Resistance to Methyl Viologen (Paraquat)
(East Carolina University, 1998-04)In this study, we cloned the Pseudomonas aeruginosa zwf gene, encoding glucose-6-phosphate dehydrogenase (G6PDH), an enzyme that catalyzes the NAD1- or NADP1-dependent conversion of glucose-6-phosphate to 6-phosphogluconate. ... -
Characterizations of Cross-Bridges in the Presence of Saturating Concentrations of MgAMP-PNP in Rabbit Permeabilized Psoas Muscle
(1998-06)Several earlier studies have led to different conclusions about the complex of myosin with MgAMP-PNP. It has been suggested that subfragment 1 of myosin (S1)-MgAMP-PNP forms an S1-MgADP-like state, an intermediate between ... -
Identification and mapping of two divergent, unlinked major histocompatibility complex class II B genes in Xiphophorus fishes.
(East Carolina University, 1998-08)We have isolated two major histocompatibility complex (MHC) class II B genes from the inbred fish strain Xiphophorus maculatus Jp 163 A. We mapped one of these genes, designated here as DXB, to linkage group III, linked ... -
Tensions in setting health care priorities for South Africa's children.
(East Carolina University, 1998-08)The new South African constitution commits the government to guarantee "basic health services "for every child under 18. Primary health care for pregnant women and children under six and elements of essential primary health ...
