It has long been known that psychostimulant drugs have the paradoxical effect of reducing hyperactivity. [Psychostimulant drugs include methylphenidate – known by the trade names Ritalin, Concerta, and Methylin – and methamphetamine]. Since the mid-1950s, millions of children and adults have been prescribed stimulant medications to control attention deficit hyperactivity ...

(SUNY Downstate Medical Center) It has long been known that psychostimulant drugs have the paradoxical effect of reducing hyperactivity. But for more than seven decades, since the first experiment that gave an amphetamine drug to children diagnosed with behavioral problems, scientists have not known how stimulants work to control hyperactivity. ...

National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found ...

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.

For patients with incurable pulmonary conditions, a lung transplantation is the only available treatment option. However, suitable donor organs are scarce, and even getting them to prospective recipients is not easy. As Professor Alexander Dietrich of the Walther Straub Institute of Pharmacology and Toxicology at LMU explains, "An isolated lung ...

Long duration, controllable drug delivery is of wide interest to medical researchers and clinicians, particularly those seeking to improve treatment for patients with chronic pain or to prevent cancer recurrence after surgery. Now a team of researchers led by Boston University Biomedical Engineer and Chemist Mark Grinstaff has developed a ...

According to a recent study, there is a new mechanism of drug release using 3D superhydrophobic materials that utilizes air as a removable barrier to control the rate at which drug is released. The study was electronically published in the Journal of the American Chemical Society...

A key feature of human and animal brains is that they are adaptive; they are able to change their structure and function based on input from the environment and on the potential associations, or consequences, of that input. For example, if a person puts his hand in a fire and ...
