Intact Purine Biosynthesis Pathways Are Required for Wild-Type Virulence of Brucella abortus 2308 in the BALB/c Mouse Model
(East Carolina University, 2004-08)Brucella abortus 2308 derivatives with mini-Tn5 insertions in purE, purL, and purD display significant attenuation in the BALB/c mouse model, while isogenic mutants with mini-Tn5 insertions in pheA, trpB, and dagA display ... -
Ca2+ and Ionic Strength Dependencies of S1-ADP Binding to Actin-Tropomyosin-Troponin: Regulatory Implications
(East Carolina University, 2004-09)Skeletal and cardiac muscle contraction are inhibited by the actin-associated complex of tropomyosin-troponin. Binding of Ca21 to troponin or binding of ATP-free myosin to actin reverses this inhibition. Ca21 and ATP-free ... -
Comparative genomics of cyclin-dependent kinases suggest co-evolution of the RNAP II C-terminal domain and CTD-directed CDKs
(East Carolina University, 2004-09-20)Background: Cyclin-dependent kinases (CDKs) are a large family of proteins that function in a variety of key regulatory pathways in eukaryotic cells, including control over the cell cycle and gene transcription. Among the ... -
Pseudomonas aeruginosa relA Contributes to Virulence in Drosophila melanogaster
(East Carolina University, 2004-10)The stringent response is a mechanism by which bacteria adapt to nutritional deficiencies through the production of the guanine nucleotides ppGpp and pppGpp, produced by the RelA enzyme. We investigated the role of the ... -
Unique V3 Loop Sequence Derived from the R2 Strain of HIV-Type 1 Elicits Broad Neutralizing Antibodies
(East Carolina University, 2004-11)DNA vaccines expressing the envelope (Env) of the human immunodeficiency virus type 1 (HIV-1) have been relatively ineffective at generating high-titer, long-lasting, neutralizing antibodies. In this study, DNA vaccines ... -
Functional Characterization of a Small Conductance GIRK Channel in Rat Atrial Cells
(East Carolina University, 2004-11)Muscarinic K1 (KACh) channels are key determinants of the inhibitory synaptic transmission in the heart. These channels are heterotetramers consisting of two homologous subunits, G-protein-gated inwardly rectifying K1 ... -
Raf-Induced Vascular Endothelial Growth Factor Augments Kaposi's Sarcoma-Associated Herpesvirus Infection
(East Carolina University, 2004-12)Recombinant green fluorescent protein encoding Kaposi’s sarcoma-associated herpesvirus (rKSHV.152) infection of -estradiol stimulated human foreskin fibroblasts (HFF) or HFF/ B-Raf[FF]:ER (expressing a weaker form of ... -
The delta-14 Mutation of Human Cardiac Troponin T Enhances ATPase Activity and Alters the Cooperative Binding of S1-ADP to Regulated Actin
(East Carolina University, 2004-12-07)The complex of tropomyosin and troponin binds to actin and inhibits activation of myosin ATPase activity and force production of striated muscles at low free Ca2+ concentrations. Ca2+ stimulates ATP activity, and at ... -
Cardiovascular effects in patrol officers are associated with fine particulate matter from brake wear and engine emissions
(East Carolina University, 2004-12-09)Background: Exposure to fine particulate matter air pollutants (PM2.5) affects heart rate variability parameters, and levels of serum proteins associated with inflammation, hemostasis and thrombosis. This study investigated ... -
"For ’the making and glimpsing of Other-Worlds’: Literature of the Fantastic in the Schlobin Collection at East Carolina University"
(East Carolina University, 2005)This article provides an overview of the James H. and Virginia Schlobin Literature of the Fantastic Collection at East Carolina University's Joyner Library. The collection houses materials related to science fiction and ... -
The Records of a ‘Sober, Quiet, and Industrious People’: The Archives of the Moravian Church in America, Southern Province, in Winston-Salem
(East Carolina University, 2005)This article examines the history and holdings of the Moravian Archives at the Archie K. Davis Center in Winston-Salem. -
Comparison Of The Mismatch Negativity and A Differential Waveform Response
(East Carolina University, 2005)A mismatch negativity response (MMN) and a new differential waveform were derived in an effort to evaluate a neural refractory or recovery effect in adult listeners. The MMN was elicited using oddball test runs in which ... -
Molecular and Cellular Biology Animations: Development and Impact on Student Learning
(East Carolina University, 2005)Educators often struggle when teaching cellular and molecular processes because typically they have only two-dimensional tools to teach something that plays out in four dimensions. Learning research has demonstrated that ... -
Clinical Inquiries: What interventions can help patients stop using chewing tobacco?
(East Carolina University, 2005)This review article examines current literature to recommend interventions to help patients stop using chewing tobacco. -
The UHS Nutrition Initiative: Enhancing the ability of patients, employees and the community to "Eat Smart and Move More"

(East Carolina University, 2005)This article reviews research to determine if preparticipation physical exams reduce morbidity and mortality for athletes. -
The high concentration of Arg213 → Gly extracellular superoxide dismutase (EC-SOD) in plasma is caused by a reduction of both heparin and collagen affinities
(East Carolina University, 2005-01-15)The C-terminal region of EC-SOD (extracellular superoxide dismutase) mediates the binding to both heparin/heparan sulphate and type I collagen. A mutation (Arg213→Gly; R213G) within this extracellular matrix-binding region ... -
