During nervous system development neurons extend axons which navigate along precise pathways to innervate specific target tissues, often over long distances. The distal tip of the axon, the growth cone, plays a major role in determining the direction and distance of axonal outgrowth. A variety of outgrowth-promoting or -inhibitory soluble and matrixor cell-associated molecules encountered by th...

Characterizing the mechanisms by which West Nile virus (WNV) causes blood-brain barrier (BBB) disruption, leukocyte infiltration into the brain and neuroinflammation is important to understand the pathogenesis of WNV encephalitis. Here, we examined the role of endothelial cell adhesion molecules (CAMs) in mediating the adhesion and transendothelial migration of leukocytes across human brain mic...

A great deal is now known about the cell adhesion molecules (CAMs) that are responsible for promoting the growth of ganglion cell axons as they project out of the retina through the optic nerve and finally to distant targets in the brain. However, the CAMs important for regulating axon outgrowth from nonprojection neurons, such as amacrine cells and rods, are not known. Such local circuit neuro...

It has recently become clear that both extracellular matrix (ECM) glycoproteins and various cell adhesion molecules (CAMs) can promote neurite outgrowth from primary neurons, though little is known of the intracellular mechanisms through which these signals are transduced. We have previously obtained evidence that protein kinase C function is an important part of the neuronal response to lamini...

Several LIGA (Lithography Galvonoforming Abforming) test mechanisms have been designed and fabricated to study tribology and performance attributes of LIGA mechanisms. The LIGA test mechanism studied in this paper is a ratchet drive mechanism consisting primarily of pawls, cams, and springs ranging in size from about one-half millimeter to tens of millimeters of various nickel alloys fabricated...

The aim of this paper is to depict the design of a two finger parallel gripper which implements a cam-follower type transmission. This transmission is based in Slide-O-Cam, a cam mechanism with multiple rollers mounted in a common follower whose purpose is to produce a sliding motion from a rotating drive or vice versa. This transmission provides pure-rolling motion, thereby minimizing friction...

MACC-II,III, Monitoring Atmospheric Composition and Climate, is the current pre-operational Copernicus Atmosphere Monitoring Service (CAMS). It provides data records on atmospheric composition for recent years, present conditions and forecasts (a few days ahead). To support the quality assessment of the CAMS products, the EU FP7 project Network Of ground-based Remote-Sensing Observations (NORS)...

BACKGROUND Dilated cardiomyopathy (DCM) is pathogenically linked to inflammatory cardiomyopathy (InfCM), which is characterized by intramyocardial infiltration. The transendothelial migration of immunocompetent cells is mediated by cell adhesion molecules (CAMs). METHODS AND RESULTS We investigated the expression pattern of CAMs (immunoglobulin superfamily, 32 selectins, and beta1- and beta2-...

Immunocytochemical methods were used to show that Ng-CAM (the neuron-glia cell adhesion molecule), N-CAM (the neural cell adhesion molecule), and the extracellular matrix protein cytotactin are highly concentrated at nodes of Ranvier of the adult chicken and mouse. In contrast, unmyelinated axonal fibers were uniformly stained by specific antibodies to both CAMs but not by antibodies to cytotac...

OBJECTIVE To document the prevalence of, and factors associated with, the use of complementary and alternative medicines (CAMs) for vasomotor symptoms (VMS) and other symptoms of menopause in Australian women aged 40-65 years. DESIGN, SETTING AND PARTICIPANTS Cross-sectional questionnaire-based study of Australian women aged 40-65 years living independently in the community. Women able to com...
