Sodium Channel Inactivation Goes with the Flow
Voltage-dependent inactivation of Na ϩ channels is a consequence of voltage-dependent activation (Aldrich et al., 1983), and inactivation is characterized by at least two distinguishable kinetic components: an initial rapid component (fast inactivation) and a slower component (slow inactivation). Within milliseconds of opening, Na ϩ channels enter a nonconducting inacti-vated state as the inact...
متن کاملHow VE-cadherin goes with the flow
Vascular endothelial cells respond to changes in blood fl ow (1). Increased fl ow, for example, causes vasodilation and blood vessel remodeling. Collectively, these responses are critical for both vascular development and the maintenance of adult blood vessels. Moreover, disturbed blood fl ow patterns—at artery branch points, for instance—can activate infl ammatory pathways that may initiate th...
متن کاملColorectal neoplasia goes with the flow: prostaglandin transport and termination.
The past 10 to 15 years have witnessed major advances in our understanding of polyunsaturated fatty acid metabolism involving synthesis, activity, and degradation of prostaglandin (PG), especially prostaglandin E2 (PGE2), in neoplasia, in particular colorectal neoplasia. Little is known, however, about the role of PG transport in these processes. The flow of PGs in and out of colorectal cells i...
متن کاملAs Water Flows , So Goes the Health of Our Coasts
L use has an enormous impact on the coastal aquatic system of the Chesapeake Bay, Maryland, USA.The problems associated with land use and land management practices on the Chesapeake Bay are amplified by the high ratio of land to water. Thus, widespread land use changes significantly impact the bay’s hydrology, water quality and ecology.These impacts promoted a sequence of management initiatives...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
