Brain Protein "Rescues" Neurons From Atrophy

...her different parts of the visual cortex responded particularly to specific neurotrophins. Such a differential response would help confirm that neurotrophins are not simply a general growth enhancer for neurons, but represent a sort of chemical "language" that specifically regulates how different kinds of neurons...

Bee Sting Treatment Should Emphasize Speed, Not Method Of Removal

... to bee stings, removingthe sting rapidly could be particularly important, Visscher said. Systemicallergic reactions are dose dependent, so the faster a sting is removed,the less venom is injected, and the less likely a person is to have dangerouswhole-body responses like constriction of breathing or a drop in bl...

Component In Soy Products May Be Substitute For Estrogen Treatment

"Soy isoflavones act like weakestrogens in respect to bone metabolism. Maybe postmenopausal women canuse soy products instead of estrogen replacement. Maybe women at-risk forbreast can...

New Software Provides Quick Analysis of ion-Channel Activity

...could make a tremendous difference in drug design, particularly for conditions where ion channels are implicated. For example, in people who have some kinds of inherited neuromuscular diseases, an amino acid in the receptors for the neurotransmitter has been altered, he said. These alterations cause the ion cha...
