to dramatically increase their activity and the output of dopamine. Eventually, the norepineprhine neurons die, the surviving dopamine neurons lose their ability to release extra dopamine, and symptoms start to appear." To test their hypothesis, th...
Regulator of lipid metabolism ensures high quality breast milk
...D., observed that mice lacking PPAR in endothelial cells
had trouble rearing their newborns. Although the mothers seemed perfectly normal, the nursing offspring soon stopped growing and lost their hair, says Wan. It took us some time to figure out what was going on. If the pups were given anti-inflammato...
