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 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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Th1 Adjuvant N-Acetyl-d-Glucosamine Polymer Up-Regulates Th1 Immunity but Down-Regulates Th2 Immunity against a Mycobacterial Protein (MPB-59) in Interleukin-10-Knockout and Wild-Type Mice
(East Carolina University, 2001-10)Treatment of mice with heat-killed (HK) Mycobacterium bovis BCG or 1- to 10-μm chitin particles (nonantigenic N-acetyl-d-glucosamine polymers) is known to induce innate immune responses, including gamma interferon (IFN-γ) ... -
Oral citrulline as arginine precursor may be beneficial in sickle cell disease: early phase two results.
(East Carolina University, 2001-10)L-Arginine may be a conditionally essential amino acid in children and adolescents with sickle cell disease, particularly as required substrate in the arginine-nitric oxide pathway for endogenous nitrovasodilation and ... -
LOCAL ADMINISTRATION OF CARBON MONOXIDE INHIBITS NEOINTIMA FORMATION IN BALLOON INJURED RAT CAROTID ARTERIES
(2005)Recent studies indicate that systemic induction of heme oxygenase-1 (HO-1), which oxidatively degrades heme into iron, biliverdin, and carbon monoxide (CO), or adenoviral-mediated gene transfer of HO-1 inhibits neointima ... -
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 ... -
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 ... -
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

Transplantation of GABAergic Neurons but not Astrocytes Induces Recovery of Sensorimotor Function in the Traumatically Injured Brain
(East Carolina University, 2007-04-16)Embryonic stem (ES) cells have been investigated in many animal models of injury and disease. However, few studies have examined the ability of pre-differentiated ES cells to improve functional outcome following traumatic ... -
Role of neuronal nitric oxide in the regulation of vasopressin expression and release in response to inhibition of cathecholamine synthesis and dehydration
(East Carolina University, 2007-10-22)We used neuronal nitric oxide synthase (nNOS) gene knockout mice to study the effects of catecholamines and neuronal nitric oxide on vasopressin expression in the hypothalamic neurosecretory centers. nNOS gene deletion ... -
Mechanism for Improved Insulin Sensitivity after Gastric Bypass Surgery
(East Carolina University, 2008-12)Context: Surgical treatments of obesity have been shown to induce rapid and prolonged improvements in insulin sensitivity. Objective: The aim of the study was to investigate the effects of gastric bypass surgery and the ... -
The role of mediators of neuronal plasticity in the circadian regulation of suprachiasmatic nucleus by light
(East Carolina University, 2009)Circadian rhythms are highly conserved physiological functions that are present in almost all living organisms. In mammals, circadian rhythms are synchronized to the environmental light:dark cycle by daily adjustments in ... -
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 ... -
YC-1 Stimulates the Expression of Gaseous Monoxide-Generating Enzymes in Vascular Smooth Muscle Cells
(East Carolina University, 2009-01)The benzylindazole derivative 3-(5′-hydroxymethyl-2′-furyl)-1-benzyl indazole (YC-1) is an allosteric stimulator of soluble guanylate cyclase (sGC) that sensitizes the enzyme to the gaseous ligands carbon monoxide (CO) and ... -
