Study finds no significant side effects in children treated up to two years
new study has found that an all-day, extended-release stimulant for treating attention-deficit hyperactivity disorder (ADHD) remains effective for up to two years without significant side effects. In the October issue of the Journal of the American Association of Child & Adolescent Psychiatry, a multi-institutional research team reports finding that treatment with Concerta, a once-daily form of the drug methylphenidate, successfully controlled ADHD symptoms in more than 200 children with ADHD. The study was supported by McNeil Pharmaceuticals, which manufactures Concerta.
"Although ADHD is recognized as a chronic disease, weve known very little about the effects of chronic treatment," says Timothy Wilens, MD, of the Massachusetts General Hospital (MGH) Pediatric Psychopharmacology Unit, lead author of the JAACAP report. "There have been concerns about whether the stimulant medications that are a mainstay of treatment continue to be effective, whether patients build up tolerance, or whether the drugs might have adverse effects on cardiovascular health or growth. This investigation sheds some important light on those questions."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
