A central problem in cellular immunology is the elucidation of the nature of the antigen receptor molecules on the surface of thymus-dependent lymphocytes (T cells). Antigen receptors on thymus-independent lymphocytes (B cel|s) are readily detectable and have been identified as being mainly monomeric IgM molecules (1-6). However direct attempts to demonstrate immunoglobulin (Ig) molecules on th...
between the two spaces when water diffuses freely across the membrane. The predominant solute of the extracellular space is sodium. Various disease states may alter water balance and lead to abnormally high or low sodium levels that may result in significant disability or death from either the causative disease, the direct effects of the sodium concentration, or the ill effects of inappropriate...
The authors examined 13 skilled and 12 novice tennis performers’ ability to use visual information of an opponent’s movement pattern to anticipate and respond. In Experiment 1, skilled and novice players anticipated the type of stroke and the direction in which the ball was hit in a highly coupled perception–action environment. Both groups of players correctly anticipated at greater than chance...
Racial Harassment, Job Satisfaction and Intentions to Quit: Evidence from the British Nursing Profession This paper investigates the determinants of racial harassment at the workplace and its impact, via job satisfaction, on intentions to quit. Using data for ethnic minority nurses in Britain, we find that nearly 40% of nurses have experienced racial harassment from work colleagues, whilst more...

This is drawn from an extremely wide range journals, including IEEE Journal Photovoltaics, Solar Energy Materials Cells, Renewable Energy, Sustainable Reviews, Applied Physics, Physics Letters. To assist re...
Vascular endothelial growth factor (VEGF)-A, a family of differentially spliced proteins produced by glomerular podocytes, maintains glomerular filtration barrier function. The expression of VEGF molecules is altered in human nephropathy. We aimed to determine the roles of the angiogenic VEGF(164) isoform, and the antiangiogenic VEGF(165)b isoform in mature, adult glomeruli in vivo using condit...
