Association of pneumothorax and hypotension with intraventricular haemorrhage
(East Carolina University, 1991-01)
To test the hypothesis that acute hyotension resulting from pneumothorax would be associated with severe brain injury (grade 3 or 4 intraventricular haemorrhage), 67 very low birthweight (VLBW) infants of 32 weeks' gestation ...
Quinolone signaling in the cell-to-cell communication system of Pseudomonas aeruginosa
(East Carolina University, 1999-09-28)
Numerous species of bacteria use an elegant
regulatory mechanism known as quorum sensing to control
the expression of specific genes in a cell-density dependent
manner. In Gram-negative bacteria, quorum sensing ...
Characterization of a Peroxide-Resistant Mutant of the Anaerobic Bacterium Bacteroides fragilis
(East Carolina University, 1998-11)
A Bacteroides fragilis mutant resistant to hydrogen peroxide and alkyl peroxide was isolated by enrichment
in increasing concentrations of hydrogen peroxide. The mutant strain was constitutively resistant to 100 mM
H2O2 ...
Molecular and genetic analysis of the Bacteroides uniformis cephalosporinase gene, cblA, encoding the species-specific beta-lactamase.
(East Carolina University, 1994-08)
The gene, cbl, encoding the species-specific, clavulanate-susceptible, endogenous cephalosporinase was cloned from Bacteroides uniforinis WAL-7088. The nucleotide sequence was determined, and the cbl structural gene was ...
Characterization of the avian GLUT1 glucose transporter: differential regulation of GLUT1 and GLUT3 in chicken embryo fibroblasts.
(East Carolina University, 1995-11)
Vertebrate cells that are transformed by oncogenes such as v-src or are stimulated by mitogens have increased rates of glucose uptake. In rodent cels, the mechanisms whereby glucose transport is up-regulated are well ...
Cloning and characterization of the endogenous cephalosporinase gene, cepA, from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases.
(East Carolina University, 1993-11)
Bacteroides frgiglis CS30 is a clinical isolate resistant to high concentrations of benzylpenicillin and cephaloridine but not to cephamycin or penem antibiotics. beta-Lactam resistance is mediated by a chromosomally encoded ...
Identification of a circular intermediate in the transfer and transposition of Tn4555, a mobilizable transposon from Bacteroides spp.
(East Carolina University, 1993-05)
Transmissible cefoxitin (FX) resistance in Bacteroides vulgatus CLA341 was associated with the 12.5-kb,
mobilizable transposon, Tn4555, which encoded the 13-lactamase gene cfxA. Transfer occurred by a
conjugation-like ...
Oxidative stress response in an anaerobe, Bacteroides fragilis: a role for catalase in protection against hydrogen peroxide.
(East Carolina University, 1996-12)
Survival of Bacteroides fragilis in the presence of oxygen was dependent on the ability of bacteria to synthesize
new proteins, as determined by the inhibition of protein synthesis after oxygen exposure. The B. fragilis ...
Regulation of Bacteriodes fragilis katB mRNA by oxidative stress and carbon limitation.
(East Carolina University, 1997-11)
Regulation of the katB catalase gene in the anaerobic bacterium Bacteroides fragilis was studied. Northern
blot hybridization analyses revealed that katB was transcribed as an approximately 1.6-kb monocistronic
mRNA. The ...
The pseudorabies virus UL28 protein enters the nucleus after coexpression with the herpes simplex virus UL15 protein
(East Carolina University, 1997-12)
Herpesvirus DNA is packaged into capsids in the nuclei of infected cells in a process requiring at least six
viral proteins. Of the proteins required for encapsidation of viral DNA, UL15 and UL28 are the most conserved
among ...
