Allopurinol improves myocardial reperfusion injury in a xanthine oxidase-free model
(East Carolina University, 1995-07)The ability of allopurinol to protect against reperfusion injury in the heart has usually been attributed to its xanthine oxidase (XO)- inhibiting properties. Human myocardium how- ever, has exhibited low levels of XO ... -
Alveolar macrophage priming by intravenous administration of chitin particles, polymers of N-acetyl-D-glucosamine, in mice
(East Carolina University, 1997-03)Intravenous (i.v.) administration of phagocytosable chitin particles (1 to 10 mm) in C57BL/6 mice and SCID mice primed alveolar macrophages (Mf) within 3 days to yield up to a 50-fold increase in their oxidative burst when ... -
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 ... -
Anti-growth properties of BAY 41-2272 in vascular smooth muscle cells
(East Carolina University, 2009-02)Vascular smooth muscle (VSM) growth is integral in the pathophysiology of blood vessel diseases, and identifying approaches that have capacity to regulate VSM growth is critically essential. Cyclic nucleotide signaling has ... -
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 ... -
Augmented coronary vascular smooth muscle response to endothelin-1 exacerbates cardiac injury following pulmonary exposure to engineered nanomaterials
(East Carolina University, 2014)Multi-walled carbon nanotubes (MWCNT) and 60-carbon fullerenes (C60) are important engineered nanoparticles (ENP) used across industry. Exposure to ENP potentially promotes cardiovascular detriments. The hypotheses that ... -
Brain-derived neurotrophic factor and neurotrophin receptors modulate glutamate-induced phase shifts of the suprachiasmatic nucleus
(East Carolina University, 2006-08)Light information reaches the suprachiasmatic nucleus (SCN) through a subpopulation of retinal ganglion cells. Previous work raised the possibility that brain-derived neurotrophic factor (BDNF) and its high-affinity ... -
A broader view of animal research

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 ... -
Contractile activity restores insulin responsiveness in skeletal muscle of obese Zucker rats.
(East Carolina University, 1993-01-15)Both insulin and contraction stimulate glucose transport in skeletal muscle. Insulin-stimulated glucose transport is decreased in obese humans and rats. The aims of this study were (1) to determine if contraction-stimulated ... -
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 ... -
The effect of fasting on the activation in vivo of the insulin receptor kinase.
(East Carolina University, 1990-02-01)Fasting causes insulin resistance in liver and fat, and increases insulin sensitivity in muscle. We studied the response in vitro and in vivo to insulin of the insulin receptor tyrosine kinase in muscle and liver from 72 ... -
Effects of Aerobic Capacity Phenotype on Adaptive Responses to Ischemic Stress
(East Carolina University, 2009)Ischemic disease leads to increased tissue stress by decreasing supply of nutrients adequate to meet energy demands. To maintain functionality, compensatory mechanisms for diminished vascular supply are induced by numerous ... -
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 ... -
An in vitro human muscle preparation suitable for metabolic studies. Decreased insulin stimulation of glucose transport in muscle from morbidly obese and diabetic subjects.
(East Carolina University, 1988-08)We have developed an in vitro muscle preparation suitable for metabolic studies with human muscle tissue and have investigated the effects of obesity and non-insulin-dependent diabetes mellitus (NIDDM) on glucose transport. ... -
The induction of antigen-specific immunological tolerance and attenuation of inflammation via cytokine antigen fusion protein therapy in a mouse model of pulmonary inflammation
(East Carolina University, 2014)Allergic asthma is a significant medical issue, affecting more than 300 million individuals and causing approximately 250,000 deaths each year. Current asthma therapies temporarily minimize discomfort and manage symptoms, ... -
Influence of carbon nanomaterial exposure on pro-constrictor mechanisms during pregnancy
(East Carolina University, 2013)Engineered carbon based nanoparticles (CNP) such as fullerenes and multiwalled carbon nanotubes (MWCNTs) are increasingly used in industries and in nanomedicine as a platform for drug delivery. Following environmental/o ... -
Inhibition by rapamycin of ornithine decarboxylase and epithelial cell proliferation in intestinal IEC-6 cells in culture
(East Carolina University, 1997-02)1 Induction of the enzyme ornithine decarboxylase (ODC) appears to be controlled primarily at the level of ODC mRNA translation. The immunosuppressant drug, rapamycin, blocked the induction of ODC in response to serum ... -
Multiple Kinase Involvement in the Regulation of Vascular Growth
(New York: InTech Open Access Publishers, 2012-06)The initial discovery of protein phosphorylation as a regulatory mechanism for the control of glycogen metabolism has led to intense interest of protein phosphorylation in regulating protein function (Cohen et al., 2001). ... -
