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 ...
The Effect of Drawing to Enhance Word Retrieval in Individuals with Chronic Severe Aphasia
(East Carolina University, 2012)
The purpose of the current study was to examine if individuals with severe chronic aphasia could increase their ability to retrieve object names by implementing the compensatory strategy of drawing. This unique treatment ...
Opsonized Virulent Brucella abortus Replicates within Nonacidic, Endoplasmic Reticulum-Negative, LAMP-1-Positive Phagosomes in Human Monocytes
(East Carolina University, 2005-06)
Cells in the Brucella spp. are intracellular pathogens that survive and replicate within host monocytes. Brucella maintains persistent infections in animals despite the production of high levels of anti-Brucellaspecific ...
Two Distinct Pathways Supply Anthranilate as a Precursor of the Pseudomonas Quinolone Signal
(East Carolina University, 2007-05)
Pseudomonas aeruginosa is an opportunistic pathogen that causes serious infections in immunocompromised patients and those with cystic fibrosis (CF). This gram-negative bacterium uses multiple cell-to-cell signals to control ...
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 ...
A Multicomponent System Is Required for Tetracycline-Induced Excision of Tn4555
(East Carolina University, 2004-01)
Bacteroides spp. are the predominant organisms in the intestinal tract, and they also are important opportunistic
pathogens. Antibiotic therapy of Bacteroides infections often is complicated by the prevalence of
drug-resistant ...
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 ...
