ITE JOURNAL ON THE WEB / MAY 1999 OVER THE PAST DECADES traffic volumes have been steadily increasing throughout the United States causing more congestion and compromising safety. Highway incidents can cause significant disruption to traffic flows, and their adverse effects are usually widespread. The long delays usually experienced as a result of these incidents reduce productivity and increas...

Enzymes are biological catalysts vital to life processes and have attracted century-long investigation. The classic Michaelis-Menten mechanism provides a highly satisfactory description of catalytic activities for large ensembles of enzyme molecules. Here we tested the Michaelis-Menten equation at the single-molecule level. We monitored long time traces of enzymatic turnovers for individual b-g...

spinal cord injury (sci) actuate to complex cellular and molecular interactions within the central nervous system in a heave to repair the initial tissue damage. the pathophysiology of acute spinal cord injury (sci) involves primary and secondary mechanisms. neuroinflammation is an important secondary injury process in sci. the local inflammatory microenvironment within the injured spinal cord ...

The relationship between biliary excretion in sandwich-cultured rat hepatocytes and in vivo in rats was examined. The biliary excretion of seven model substrates in 96-h sandwich-cultured rat hepatocytes was determined by differential cumulative uptake of substrate in the monolayers preincubated in standard buffer (intact bile canaliculi) and Ca2+-free buffer (disrupted bile canaliculi). Biliar...

Monocytes/macrophages serve as sentinels involved in chronic inflammation and the eradication of various pathogens. To define molecularly the differentiation of blood monocytes into macrophages, we conducted serial analysis of gene expression (SAGE) in human blood monocytes/ macrophages induced by granulocyte-macrophage colonystimulating factor (GM-CSF) or M-CSF. SAGE analysis of 57,560, 57,463...
