Functions Required for Extracellular Quinolone Signaling by Pseudomonas aeruginosa
(East Carolina University, 2002-12)
A set of 30 mutants exhibiting reduced production of the phenazine poison pyocyanin were isolated following transposon mutagenesis of Pseudomonas aeruginosa PAO1. The mutants could be subdivided into those with defects in ...
What Constitutes an Extended-Spectrum beta-lactamase?
(East Carolina University, 2002-02)
Aerobic-Type Ribonucleotide Reductase in the Anaerobe Bacteroides fragilis
(East Carolina University, 2002-02)
Bacteroides fragilis, a component of the normal intestinal flora, is an obligate anaerobe capable of long-term survival in the presence of air. Survival is attributed to an elaborate oxidative stress response that controls ...
Response to Kuhse
(East Carolina University, 2002-08)
In this short paper, we respond to critics of our original paper, The agony of agonal respiration: is the
last gasp necessary?. A common thread in both Hawryluckâ s and Kuhseâ s responses is the difficulties
encountered ...
Nonreceptor Tyrosine Kinase c-Yes Interacts with Occludin during Tight Junction Formation in Canine Kidney Epithelial Cells
(East Carolina University, 2002-04)
Occludin is an integral membrane protein that is tyrosine phosphorylated when localized at tight junctions. When Ca2 was depleted from the culture medium, occludin tyrosine phosphorylation was diminished from Madin-Darby ...
Brachial plexopathy after prone positioning
(East Carolina University, 2002-12)
Two cases of brachial plexus injury after prone position in the intensive care unit are described. Mechanisms of brachial plexus injury are described, as are methods for prevention of this unusual complication. Originally ...
Troponin-tropomyosin: an allosteric switch or a steric blocker?
(East Carolina University, 2002-08)
The interaction of myosin subfragment 1 (S1) with actin-tropomyosin-troponin (regulated actin) is highly nucleotide dependent. The binding of S1 or S1-ADP (but not S1-ATP nor N,N - -phenylenedimaleimide-modified S1-ATP) ...
Autolysis and Autoaggregation in Pseudomonas aeruginosa Colony Morphology Mutants
(East Carolina University, 2002-12)
Two distinctive colony morphologies were noted in a collection of Pseudomonas aeruginosa transposon insertion mutants. One set of mutants formed wrinkled colonies of autoaggregating cells. Suppressor analysis of a subset ...
Deficiency of a Sinorhizobium meliloti bacA Mutant in Alfalfa Symbiosis Correlates with Alteration of the Cell Envelope
(East Carolina University, 2002-10)
The BacA protein is essential for the long-term survival of Sinorhizobium meliloti and Brucella abortus within acidic compartments in plant and animal cells, respectively. Since both the S. meliloti and B. abortus bacA ...
Novel autoinducer molecules and uses therefor
(2002-03-07)
Novel bacterial quinolone signal molecules and, more particularly, pseudomonas quinolone signal ('PQS') molecules, e.g., 2-heptyl-3hydroxy-4-quinolone, and analogs and derivatives thereof are described, Therapeutic ...
