It is also important tonote that our study demonstrates that the actual dose of BPA exposuremay change the biological response,?Dr. Knudsen said.The safety of BPA has been under intense debate for several years, withsome arguing that exposure to the chemical among humans...

Beyond lithium for bipolar disorder

... Lithium is known to inhibit the production of an important cellular switch, called inositol monophosphate, so the researchers set out to find genes that were activated by this inhibition. They treated slices of rat brain with lithium chloride as well as a chemical that depletes inositol. The also treated oth...

...nomers become irreversible. Defining that point is important because "the fibrils are virtually indestructible once formed," he said. "How all these monomers interact to form these amyloid fibrils is just not known at this point," said Akhremitchev. "And that is why it is such a great challenge. That's what w...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

...or of Icmt, a protein that has been shown to be an important player in keeping a cancer-causing gene called 'Ras' turned on inside cells," said Casey. Ras is a normal genetic component of the cell, but mutations in the gene can cause it to become stuck in an "on" position, promoting uncontrolled cell growth. ...
