The Brucella abortus Cu,Zn Superoxide Dismutase Is Required for Optimal Resistance to Oxidative Killing by Murine Macrophages and Wild-Type Virulence in Experimentally Infected Mice
(East Carolina University, 2005-05)Two-dimensional gel electrophoretic analysis of cell lysates from Brucella abortus 2308 and the isogenic hfq mutant Hfq3 revealed that the RNA binding protein Hfq (also known as host factor I or HF-I) is required for the ... -
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 ... -
Regulation of Pseudomonas Quinolone Signal Synthesis in Pseudomonas aeruginosa
(East Carolina University, 2005-07)Pseudomonas aeruginosa is an opportunistic pathogen that causes chronic lung infections in cystic fibrosis patients and is a major source of nosocomial infections. This bacterium controls many virulence factors by using ... -
Identification and Characterization of Optimal Gene Expression Markers for Detection of Breast Cancer Metastasis
(East Carolina University, 2005-08)Sentinel lymph node (SLN) status is highly predictive of overall axillary lymph node involvement in breast cancer. Historically, SLN-positive patients have undergone axillary lymph node dissection in a second ... -
A Novel A1 Adenosine Receptor Antagonist, L-97-1 [3-[2-(4-Aminophenyl)-ethyl]-8-benzyl-7-{2-ethyl-(2-hydroxy-ethyl)-amino]-ethyl}-1-propyl-3,7-dihydro-purine-2,6-dione], Reduces Allergic Responses to House Dust Mite in an Allergic Rabbit Model of Asthma
(East Carolina University, 2005-10)Adenosine, an important signaling molecule in asthma, produces bronchoconstriction in asthmatics. Adenosine produces bronchoconstriction in allergic rabbits, primates, and humans by activating A1 adenosine receptors (ARs). ... -
Adaptations of Pseudomonas aeruginosa to the Cystic Fibrosis Lung Environment Can Include Deregulation of zwf, Encoding Glucose-6-Phosphate Dehydrogenase
(East Carolina University, 2005-11)Cystic fibrosis (CF) patients are highly susceptible to chronic pulmonary disease caused by mucoid Pseudomonas aeruginosa strains that overproduce the exopolysaccharide alginate. We showed here that a mutation in zwf, ... -
The effect of brevenal on brevetoxin-induced DNA damage in human lymphocytes
(East Carolina University, 2005-11)Brevenal is a nontoxic short-chain trans-syn polyether that competes with brevetoxin (PbTx) for the active site on voltage-sensitive sodium channels. The PbTxs are highly potent polyether toxins produced during blooms of ... -
Predifferentiated Embryonic Stem Cells Prevent Chronic Pain Behaviors and Restore Sensory Function Following Spinal Cord Injury in Mice
(East Carolina University, 2006)Embryonic stem (ES) cells have been investigated in repair of the CNS following neuronal injury and disease; however, the efficacy of these cells in treatment of postinjury pain is far from clear. In this study, we evaluated ... -
Healthy Hospital Food Environment: the PCMH Story.
(2006)This paper describes Pitt Memorial Hospital's response to the call to become a healthy worksite. It describes the hospital's effots to partner in the North Carolina Plan to Prevent Overweight and Obesity and Related Chronic ... -
Characterization of the Vaccinia Virus A35R Protein and Its Role in Virulence
(East Carolina University, 2006-01)The vaccinia virus A35R gene is highly conserved among poxviruses and encodes a previously uncharacterized hydrophobic acidic protein. Western blotting with anti-A35R peptide antibodies indicated that the protein is ... -
Orchiectomy or androgen receptor blockade attenuates baroreflex-mediated bradycardia in conscious rats
(East Carolina University, 2006-01)Background: Previous studies have shown that testosterone enhances baroreflex bradycardia. Therefore, conscious unrestrained rats were used to investigate the role of the androgen receptor in the testosterone-mediated ... -
Identification, cloning and functional characterization of novel beta-defensins in the rat (Rattus norvegicus)
(East Carolina University, 2006-02-04)Background beta-defensins are small cationic peptides that exhibit broad spectrum antimicrobial properties. The majority of beta-defensins identified in humans are predominantly expressed in the male reproductive tract ... -
Human antibodies for immunotherapy development generated via a human B cell hybridoma technology
(East Carolina University, 2006-03-07)Current strategies for the production of therapeutic mAbs include the use of mammalian cell systems to recombinantly produce Abs derived from mice bearing human Ig transgenes, humanization of rodent Abs, or phage ... -
Characterization of Bacteroides fragilis Hemolysins and Regulation and Synergistic Interactions of HlyA and HlyB
(East Carolina University, 2006-04)This study describes the presence of 10 hemolysin orthologs in the genome of the opportunistic human anaerobic pathogen Bacteroides fragilis, which is currently classified as a nonhemolytic bacterium. The hemolysins were ... -
Raman spectroscopy: the gateway into tomorrow's virology
(East Carolina University, 2006-06-28)In the molecular world, researchers act as detectives working hard to unravel the mysteries surrounding cells. One of the researchers' greatest tools in this endeavor has been Raman spectroscopy. Raman spectroscopy is a ... -
Characterization of the Primary Starch Utilization Operon in the Obligate Anaerobe Bacteroides fragilis: Regulation by Carbon Source and Oxygen
