New evidence suggests reconsidering causes and treatments for schizophrenia
...eep studies. The muscarinic cholinergic system exerts a strong influence over REM -- or dream -- sleep, especially the first dream phase after onset of sleep. Therefore, Tandon says, they set out to examine what happens when drug-free schizophrenic patients have their muscarinic cholinergic system chall...New understanding of a key control mechanism in the brain
...ow this small population (10-20% of brain neurons) exerts its controlling effect on the brain. Pivotal for normal brain development, learning, and memory, it is not surprising that inhibitory neurons are involved in most neurological disorders. A recent study at the Weizmann Institute of Science, published ...New study confirms importance of systolic blood pressure
...ients." Systolic pressure measures the force blood exerts on the artery walls when theheart beats, and diastolic pressure measures the force on the arteries betweenheartbeats. Hypertension is diagnosed when the systolic blood pressure is 140mm Hg or higher or the diastolic blood pressure is 90 mm Hg or hig...Correlation between brain shrinkage and education found
... older adults. "Our research shows that education exerts a protective effect," said C. EdwardCoffey, M.D., chair of Henry Ford's Department of Psychiatry and the study'sprincipal investigator. "Education doesn't reduce brain changes associated withdisease or aging, but rather enables more educated individu...Circulation publishes phase I study of ENBREL in patients with chronic heart failure
... in increasedamounts in damaged heart tissue. TNF exerts its effects by interacting withspecific TNF receptors that are on the surface of cells. When TNF binds withTNF receptors, it sets off a chain of events within the cell that may lead tofurther damage to the heart.

The precise mechanism by which EECP exerts its long-term beneficial effect isunknown, said Richard Nesto, MD, associate professor of medicine at HarvardMedical School and senior author of the paper in the Journal of the AmericanCollege of Cardiology. "This will open up new scientific areas,"...Research Explains Lithium's Dual Anti-Manic/Anti-Depressive Effect
...the researchers found that in mice brains, lithium exerts a push/pulleffect on the neurotransmitter glutamate, eventually causing it to level off ina stable zone where it can control both extremes. "Glutamate is the primary excitatory neurotransmitter, carrying messagesinstantaneously from one nerve cell t...Duke Study Suggests New Class Of Drugs Could Bypass Leptin Loop
... the process continues, energy burned by brown fat exerts its metabolic effectson white fat -- in essence "burning" stored white fat. In demonstrating noradrenaline's fat-burning role, Duke researchers haveexplained why leptin causes genetically obese mice to lose more weight than can be accountedfor by ap...
