Adipocytes are nowadays recognised as cells able to produce and secrete a large variety of active substances termed adipokines, which exert direct effects on vascular cells. Among these adipokines, leptin has been proposed to play a role in the pathophysiology of acute coronary syndromes, as well as in increasing cardiovascular risk. At the moment, however, the mechanisms linking leptin to card...

CXCR4 is a G protein-coupled receptor for stromal-derived factor 1 (SDF-1) that plays a critical role in leukocyte trafficking, metastasis of mammary carcinoma, and human immunodeficiency virus type-1 infection. To elucidate the mechanism for CXCR4 activation, a constitutively active mutant (CAM) was derived by coupling the receptor to the pheromone response pathway in yeast. Conversion of Asn-...

Dynein-mediated autophagosome (AP) trafficking was recently demonstrated to contribute to the formation of autophagolysosomes (APLs) and autophagic flux process in coronary arterial myocytes (CAMs). However, it remains unknown how the function of dynein as a motor protein for AP trafficking is regulated under physiological and pathological conditions. The present study tested whether the dynein...

The present study tested the hypothesis that membrane-bound NAD(P)H oxidase in coronary arterial myocytes (CAMs) is capable of producing superoxide (O(2)(*-)) toward extracellular space to exert an autocrine- or paracrine-like action in these cells. Using a high-speed wavelength-switching fluorescent microscopic imaging technique, we simultaneously monitored the binding of dihydroethidium-oxidi...

Complementary and alternative medicine (CAM) therapies—which include many natural products—are widely used alone or in combination with psychotropic drugs to treat or self-treat mental illness. It has been estimated that up to half of all individuals with a diagnosed mood disorder use 1 or more CAMs.1,2 A significant percentage of this population combines conventional pharmacological treatments...

Selected Volatile Organic Compounds (VOC) emitted from various anthropogenic sources including industries and motor vehicles act as primary precursors of ozone, while some VOC are classified as air toxic compounds. Significantly large VOC emission sources impact the air quality in Corpus Christi, Texas. This urban area is located in a semi-arid region of South Texas and is home to several large...

RATIONALE Calmodulin (CaM) mutations are associated with an autosomal dominant syndrome of ventricular arrhythmia and sudden death that can present with divergent clinical features of catecholaminergic polymorphic ventricular tachycardia (CPVT) or long QT syndrome (LQTS). CaM binds to and inhibits ryanodine receptor (RyR2) Ca release channels in the heart, but whether arrhythmogenic CaM mutants...

This review addresses issues regarding the need in the in vitro fertilization (IVF) field for further predictive markers enhancing the standing embryo selection criteria. It aims to serve as a source of defining information for an audience interested in factors related to the wide range of multiple roles played by cell adhesion molecules (CAMs) in several aspects of IVF ultimately associated wi...

This paper was aimed at developing a computer aided design and manufacturing system for spatial cylindrical cams. In the proposed system, a milling tool with a diameter smaller than that of the roller, instead of the standard cutter for traditional machining process, was used to generate the tool path for spatial cams. To verify the feasibility of the proposed method, a multi-axis machining sim...

The cell adhesion molecules (CAMs) NCAM, N-cadherin, and L1 are homophilic binding molecules that stimulate axonal growth. We have postulated that the above CAMs can stimulate this response by activating the fibroblast growth factor receptor (FGFR) in neurons. In the present study, we demonstrate that activation of NCAM and L1 can lead to phosphorylation of the FGFR. Both this and the neurite o...
