New discovery may revolutionize treatment for pain related to surgery, illness and injury
... and spinal cord, using nerves as a conduit, in an animal
model. Axonal transport works like a "conveyor-belt" process, delivering pain-relieving medication to remote sensory endings in the tissues of the body. In axonal transport, the cell moves molecules from one end of the cell to the other, thus suppo...
More evidence that soy may reduce breast cancer risk
... but it's a life-long process." He noted that some animal
studies indicate that people need to start including soy in their diet from about the time of puberty in order to gain the cancer risk-reduction benefit. The amount of isoflavones present in the urine of the women in the study correlated well wit...

perceives external pain signals. The genetically altered mouse that overexpresses NR2B, consequently enhancing the activity of NMDA receptors, provided Zhuo and colleagues with a ready-made model for exploring NR2Bs role in the forebrain. The rese...
Scientists find link between dopamine and obesity

studies conducted elsewhere, exercise has been found to increase dopamine release and to raise the number of dopamine receptors," Volkow says. This suggests that obese people might be able to boost their dopamine response through exercise instead of ...
