Arginase Promotes Neointima Formation in Rat Injured Carotid Arteries
(East Carolina University, 2009-04)Objective—Arginase stimulates the proliferation of cultured vascular smooth muscle cells (VSMCs); however, the influence of arginase on VSMC growth in vivo is not known. This study investigated the impact of arginase on ... -
Amyloid-beta peptide A beta p3-42 affects early aggregation of full-length A beta 1-42
(East Carolina University, 2009-05)The major amyloid beta (Aβ) peptides found in the brain of familial and late onset Alzheimer’s disease include the full-length Aβ1-42 and N-terminally truncated, pyroglutamylated peptides Aβp3-42 and Aβp11-42. The ... -
The cyclic GMP modulators YC-1 and zaprinast reduce vessel remodeling through anti-proliferative and pro-apoptotic effects
(East Carolina University, 2009-06)Guanosine-specific cyclic nucleotide signaling is suggested to serve protective actions in the vasculature; however, the influence of selective pharmacologic modulation of cyclic guanosine monophosphate (GMP)-synthesizing ... -
Circadian activation of mast cells mediates the nocturnal response in allergic asthma
(East Carolina University, 2010)Circadian rhythm is a conserved physiological feature of most organisms. Nocturnal symptoms are a common feature of allergic asthma in humans. Patients with nocturnal asthma show circadian variation of their pulmonary ... -
Vanadium pentoxide induces pulmonary inflammation and tumor promotion in a strain-dependent manner
(2010)Background Elevated levels of air pollution are associated with increased risk of lung cancer. Particulate matter (PM) contains transition metals that may potentiate neoplastic development through the induction of ... -
Nocturnal thoracoabdominal asynchrony in house dust mite-sensitive nonhuman primates
(2010)Nocturnal bronchoconstriction is a common symptom of asthma in humans, but is poorly documented in animal models. Thoracoabdominal asynchrony (TAA) is a noninvasive clinical indication of airway obstruction. In this study, ... -
Tissue Salvage in the Non-reperfused Myocardium Mediated by (the absence of the circadian rhythm gene) mPer2 and (the receptor tyrosine kinase) EphrinA1
(East Carolina University, 2010)Alterations in circadian rhythm have been associated with numerous cardiovascular pathologies. In project 1, we tested the hypothesis that functional mutation of the Per2 circadian clock gene would provide cardioprotection ... -
Vanadium pentoxide induces pulmonary inflammation and tumor promotion in a strain-dependent manner
(East Carolina University, 2010-04-12)Background: Elevated levels of air pollution are associated with increased risk of lung cancer. Particulate matter (PM) contains transition metals that may potentiate neoplastic development through the induction of oxidative ... -
The role of the proximal small intestine in improvements in diabetes resolution and insulin sensitivity following bariatric surgery in type 2 diabetes
(East Carolina University, 2011)Bariatric surgery is an effective, rapid, and durable treatment for obesity and type 2 diabetes mellitus (T2DM). Roux-en Y Gastric Bypass (RYGB) resolves T2DM in 80% of cases, while gastric banding (LAGB) resolves T2DM in ... -
Coronary Artery Ligation and Intramyocardial Injection in a Murine Model of Infarction
(2011)Mouse models are a valuable tool for studying acute injury and chronic remodeling of the myocardium in vivo. With the advent of genetic modifications to the whole organism or the myocardium and an array of biological and/or ... -
Identification of cytosolic phosphodiesterases in the erythrocyte: A possible role for PDE5
(2011)Background Within erythrocytes (RBCs), cAMP levels are regulated by phosphodiesterases (PDEs). Increases in cAMP and ATP release associated with activation of β-adrenergic receptors (βARs) and prostacyclin receptors ... -
DINITROBENZENES STIMULATE ELECTRON FLUX WITHIN NEURONAL NITRIC OXIDE SYNTHASE IN THE ABSENCE OF CALMODULIN
(2011)Efficient electron transfer and conversion of L-arginine to L-citrulline and nitric oxide (NO●) by neuronal nitric oxide synthase (nNOS) requires calmodulin (CaM) binding. The present study focused on electron transfer ... -
The influence of the level of physical activity and human development in the quality of life in survivors of stroke
(2011)Background The association between physical activity and quality of life in stroke survivors has not been analyzed within a framework related to the human development index. This study aimed to identify differences in ... -
Apparatus and method for measuring physiological characteristics of an intact trachea in vitro
(2011-03-15)Apparatus and methods for measuring smooth muscles responses (relaxation and contraction), transepithelial potential difference, and/or transepithelial impedance of an intact trachea in vitro. In particular embodiments, ... -
The role of cardiac mitochondria in myocardial ischemia/reperfusion injury
(East Carolina University, 2012)Cardiovascular disease (CVD) exerts economic and humanitarian costs that are unparalleled by any other disease. Of the many etiologies of CVD, myocardial infarction accounts for over 50% of the associated mortality and ... -
Expansion of cardiac ischemia/reperfusion injury after instillation of three forms of multi-walled carbon nanotubes
(2012)Background The exceptional physical-chemical properties of carbon nanotubes have lead to their use in diverse commercial and biomedical applications. However, their utilization has raised concerns about human exposure ... -
Biomarkers of Disease and Treatment in Murine and Cynomolgus Models of Chronic Asthma
(2012)Background Biomarkers facilitate early detection of disease and measurement of therapeutic efficacy, both at clinical and experimental levels. Recent advances in analytics and disease models allow comprehensive screening ... -
The significance of mirna pathway in peripheral nerve regeneration following sciatic nerve injury.
(East Carolina University, 2012)microRNAs (miRNAs) are small (21-23 nucleotides) single-stranded RNAs that play important roles in post-transcriptional regulation of gene expression. The binding of miRNA to its specific target mRNAs at 3' UTR causes ... -
