BACKGROUND AND PURPOSE M1 muscarinic ACh receptors (mAChRs) represent an attractive drug target for the treatment of cognitive deficits associated with diseases such as Alzheimer's disease and schizophrenia. However, the discovery of subtype-selective mAChR agonists has been hampered by the high degree of conservation of the orthosteric ACh-binding site(More)
Bone marrow stromal cells (BMSC) normally give rise to bone, cartilage, and mesenchymal cells. Recently, bone marrow cells have been shown to have the capacity to differentiate into myocytes, hepatocytes, and glial cells. We now demonstrate that human and mouse BMSC can be induced to differentiate into neural cells under experimental cell culture(More)
The expression of the Fos proto-oncogene protein has been used as an anatomical marker of activated brain areas. Detection of Fos immunoreactivity can provide information about the sites of action of various stimuli at the level of single cell resolution. Following intraperitoneal injection of ethanol (16% w/v), Fos immunoreactivity was induced in several(More)
The cytokine, interleukin-1 beta (IL-1 beta), can modulate both immune and neuroendocrine events. Alteration of IL-1 beta expression by exogenous factors, such as morphine, may affect the neuro-endocrine-immune axis. Brain sections from male rats implanted with either morphine or placebo pellets were stained for IL-1 beta immunoreactivity. The results(More)
OBJECTIVES To evaluate optical coherence tomographic elastography as a method for assessing the elastic properties of atherosclerotic plaque and the parameters that influence interpretation. METHODS Phantoms and aorta were examined in vitro to quantify speckle modulation and measure the displacement and strain maps. A correlation method was used as a(More)
Vitamin D receptor activation is associated with improved survival in patients with chronic kidney disease, but the mechanism of this benefit is unclear. To better understand the effects of vitamin D on endothelial function, blood pressure, albuminuria, and inflammation in patients with chronic kidney disease (2 patients stage 2, remaining stage 3), we(More)
It is thought that the physiological actions of endogenous cannabinoid arachidonylethanolamide (AEA), as well as exogenous cannabinoids such as Delta9-tetrahydrocannabinol (THC), are mediated by two subtypes of cannabinoid receptors, CB1 and CB2, which have recently been characterized. Injection of AEA leads to alterations in motor behavior and endocrine(More)
Interleukin-1 (IL-1) is a cytokine involved in a variety of biological activities. It has been hypothesized that the immunomodulatory effects of IL-1 are the result of both direct action on immune cells and indirect action on a regulatory cascade mediated through the hypothalamus. Chronic exposure to substances of abuse, such as morphine, appears to(More)
The Alzheimer's disease-related peptide beta(1-40) amyloid self-associates to form fibrils exhibiting a morphology characteristic of amyloidogenic proteins. The mechanism of this fibrillization process has yet to be fully elucidated. In this study we have immobilized the beta(1-40) amyloid to flat gold surfaces using thiol-based self-assembled monolayers.(More)
Acute hyperglycemia may contribute to the progression of atherosclerosis by regulating protein kinase C (PKC) isozymes and by accelerating vascular smooth muscle cell (VSMC) proliferation. We investigated acute glucose regulation of PKCbeta gene expression in A10 cells, a rat aortic smooth muscle cell line. Western blot analysis showed that PKCbetaII(More)
