Mast cells and the IL-33/ST2 axis are essential determinants of carbon nanotube toxicity
(East Carolina University, 2012)The rise of nanomaterial use in a variety of applications, including biomedical imaging and drug delivery, has led to concern about the potentially hazardous impacts on human health. Mast cells are critical for innate and ... -
Molecular Mechanisms of Peripheral N-Methyl-D-Aspartate Mediated Pressor Response
(East Carolina University, 2012)The primary goal of this study was to characterize the N-Methyl-D-Aspartate (NMDA) receptor within the cardiovascular system and elucidate the molecular mechanisms involved in peripheral NMDA receptor-mediated pressor ... -
Apigenin prevents chemically-induced skin tumor formation and inhibits COX-2 expression and activity in SKH-1 mouse epidermis
(East Carolina University, 2012)The most common type of cancer in the United States is non-melanoma skin cancer (NMSC), with an estimated two million new cases diagnosed each year. Numerous malignancies including NMSC, colon, breast, and prostate cancer ... -
Time Course of Altered Sensitivity to Inhibitory and Excitatory Agonist Responses in the Longitudinal Muscle-Myenteric Plexus and Analgesia in the Guinea Pig after Chronic Morphine Treatment
(2012-01)Tolerance that develops after chronic morphine exposure has been proposed to be an adaptive response that develops and decays over a defined time course. The present study examined the development of tolerance to the acute ... -
Intravenously delivered graphene nanosheets and multiwalled carbon nanotubes induce site-specific Th2 inflammatory responses via the IL-33/ST2 axis
(2013)Carbon-based nanomaterials (CBN), such as graphene nanosheets (GNS) and multiwalled carbon nanotubes (MWCNT), have been proposed for potential nanomedicine applications such as biomedical devices and carriers for drug ... -
Novel role for thioredoxin reductase-2 in mitochondrial redox adaptations to obesogenic diet and exercise in heart and skeletal muscle
(2013)Increased fatty acid availability and oxidative stress are physiological consequences of exercise (Ex) and a high-fat, high-sugar (HFHS) diet. Despite these similarities, the global effects of Ex are beneficial, whereas ... -
Smoking and dietary inadequacy among Inuvialuit women of child bearing age in the Northwest Territories, Canada
(2013)Objective The prevalence of smoking in Aboriginal Canadians is higher than non-Aboriginal Canadians, a behavior that also tends to alter dietary patterns. Compared with the general Canadian population, maternal smoking ... -
Disruption of mitochondrial fitness in human preadipocytes by fatty acids
(East Carolina University, 2013)Adipose tissue lies at the core of energy metabolism, by not only releasing and taking up fatty acids (FA) according to the individuals overall surplus or deficit of energy, but also signaling other tissues to regulate ... -
Perfluorooctanoic acid-induced developmental cardiotoxicity in an avian model
(East Carolina University, 2013)Perfluorooctanoic acid (PFOA) is a synthetic chemical used in polyfluormer production. It is a widespread environmental contaminant and is known to induce developmental toxicity in rodent models. As several related compounds ... -
Interactions of a Dopamine D Receptor Agonist with Glutamate NMDA Receptor Antagonists on the Volitional Consumption of Ethanol by the mHEP Rat
(2013-03)Stimulation of the dopamine D1 receptor is reported to cause the phosphorylation of DARPP-32 at the thre34 position and activates the protein. If intracellular Ca2+ is increased, such as after activation of the glutamate ... -
Cannabinoid receptor 1 signaling in cardiovascular regulating nuclei in the brainstem: A review
(2013-04)Cannabinoids elicit complex hemodynamic responses in experimental animals that involve both peripheral and central sites. Centrally administered cannabinoids have been shown to predominantly cause pressor response. However, ... -
Interlaboratory Evaluation of Rodent Pulmonary Responses to Engineered Nanomaterials: The NIEHS Nano GO Consortium
(2013-05)Background: Engineered nanomaterials (ENMs) have potential benefits, but they also present safety concerns for human health. Interlaboratory studies in rodents using standardized protocols are needed to assess ENM ... -
Role of central cannabinoid receptor GPR18 in cardiovascular regulation
(East Carolina University, 2014)The primary goal of this study was to characterize the role of GPR18 in the rostral ventrolateral medulla (RVLM) in blood pressure (BP) regulation and elucidate the mechanisms involved in central GPR18 mediated hypotensive ... -
The immune and neurological impacts of developmental Bisphenol A exposure in a C57bl/6 mouse model
(East Carolina University, 2014)Environmental exposure to exogenous agents during critical time points of development may be associated with the onset of deleterious effects, including immune and neurological disorders. Numerous studies have shown that ... -
Discovery and investigation of a novel role for mitochondrial prohibitin in mitigating acute heart failure in endotoxic shock
(East Carolina University, 2014)Sepsis results in more than 200,000 deaths annually and is the 10th leading cause of death in the United States (US). In spite of significant advances in medical care the mortality rate for sepsis has continued to rise. ... -
MuRF1 activity is present in cardiac mitochondria and regulates reactive oxygen species production in vivo
(2014-06)MuRF1 is a previously reported ubiquitin-ligase found in striated muscle that targets troponin I and myosin heavy chain for degradation. While MuRF1 has been reported to interact with mitochondrial substrates in yeast ... -
