VCU researchers identify networks of genes responding to alcohol in the brain

...roduction of myelin. Myelin is a form of molecular insulation that allows nerve cells to send impulses to one another more effectively. Such pathways showed different responses to alcohol in one mouse strain versus the other. As a result, Miles and his colleagues were able to formulate new hypotheses about how ...

Embryonic law and order

All commonly target RNA, shooting the messenger rather silencing the message at its source (the DNA), as many other regulatory proteins do. This may give them a relatively quick respo...

Scientists discover the molecular switch for nerve cells' insulating jelly rolls

... that turns on the production of myelin, the fatty insulation around nerve cells that ensures swift and efficient communication in the nervous system. The study, published in the September 1, 2005, issue of the journal Neuron, may provide a new avenue for treating nervous system diseases such as multiple sclero...

When myelin is stripped away through disease or injury, sensory and motor deficiencies result and, in some cases, paralysis can occur. Previous ...

Three universities team up to enhance environmental engineering curricula

New UW study offers strategy for treatment of fatal nervous system disorder

...thing that envelops nerve fibers and acts like the insulation on an electric wire. Myelin ensures the effective transmission of the signals routinely conducted by the nervous system. For those afflicted with Krabbe's disease, the loss of myelin results in arrested motor and mental development, seizures, paralys...

Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

The findings are detailed in the January edition of the peer-reviewed journal Archives of General Psychiatry and add to a g...

Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study
