Shire plc announced that DAYTRANATM (methylphenidate transdermal system), the first and only non-oral medication approved for treatment of Attention Deficit Hyperactivity Disorder (ADHD) in children aged 6 to 12 years, provided significant improvement in symptom control and tolerability, according to results of a 12-month open-label study presented at the American Psychiatric Association (APA) annual meeting in San Diego.

Findings presented today at Digestive Disease Week® 2007 (DDW), from long-term extensions of the ACT trials (Active Ulcerative Colitis 1 & 2) show that subjects with moderately to severely active ulcerative colitis (UC) who had responded to REMICADE® (infliximab) in the blinded phase of the trials maintained improvement in their clinical symptoms for up to two years.

New evidence indicates that small pieces of noncoding genetic material known as microRNAs (miRNAs) might influence cancer susceptibility. Differences in certain miRNAs may predispose some individuals to develop cancer, say researchers.

MiRNAs play a number of roles in biological regulation, including development and cell differentiation, helping to determine what type a cell ultimately becomes. But when damaged, they can contribute to cancer by either turning on cancer-causing genes or by inhibiting tumor-blocking genes. The ways that MiRNAs are expressed have been used to profile tumor types in humans.

Women who regularly enjoy an alcoholic drink or two have a significantly lower risk of having a non-fatal heart attack than women who are life-time abstainers, epidemiologists at the University at Buffalo have shown.

Moderation is the key, however. Women in the study who reported being intoxicated at least once a month were nearly three times more likely to suffer a heart attack than abstainers, results showed.

The genome of the organism that produces the world's most lethal toxin is revealed today. This toxin is the one real weapon in the genome of Clostridium botulinum and less than 2 kg - the weight of two bags of sugar - is enough to kill every person on the planet. Very small amounts of the same toxin are used in medical treatments, one of which is known as Botox®.

The genome sequence, reported in Genome Research, shows that C. botulinum doesn't have subtle tools to evade our human defences or tricky methods of acquiring resistance to antibiotics. It lives either as a dormant spore or as a scavenger of decaying animal materials in the soil, and doesn't interact with human or other large animal hosts for prolonged periods of time.

Next time there is a global pandemic, contaminated water caused by flooding, or questionable-looking meat in a supermarket, we may be reaching for a piece of paper.

It won’t be just any type of paper but a Canadian-invented bioactive paper that contains the ingredients to detect and ward off life-threatening bacteria and viruses like E-coli, salmonella and SARS, to name just a few.

Two genes important for human development and implicated in cancer and schizophrenia also help keep a healthy balance between excitation and inhibition of brain cells, researchers say.

Neuregulin-1 and its receptor, ErbB4, promote inhibition at the site of inhibitory synapses in the brain by increasing release of GABA, a major inhibitory neurotransmitter, Medical College of Georgia researchers led by Dr. Lin Mei report in the May 24 issue of Neuron.

Fragile X syndrome is the most common form of inherited mental retardation, occurring in 1 in 3600 males and 1 in 4000 to 6000 females.

To understand the details of the neuronal pathology of Fragile X syndrome, the researchers studied mice in which the same gene that causes the disease in humans had been knocked out. The scientists performed a detailed analysis of the electrophysiological properties of neurons in the prefrontal cortex, a region responsible for higher cognitive functions, including learning and memory, that are affected in humans with the disorder.

McDonald's new advertising campaign to promote high-level career opportunities within the company is a great way to fight the connotation of dead-end drudgery and low wages that comes with "McJobs," according to Jerry M. Newman, SUNY Distinguished Teaching Professor in the University at Buffalo School of Management.

Having worked undercover at seven fast-food restaurants across the United States, including McDonald's, Burger King and Wendy's, Newman, author of "My Secret Life on the McJob," says that McDonald's has the right idea in its newest television commercial.

The spot features Karen King, president of McDonald's USA East Division, extolling the virtues of the high schooler who gets a job at McDonald's, working hard and taking advantage of opportunities.

Shire plc today announced that VYVANSE™ (lisdexamfetamine dimesylate) effectively controlled Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in children aged 6 to 12 years. In addition, 95 percent of children taking VYVANSE daily for 12 months showed overall improvement, according to phase III open-label extension trial results. Further analysis of phase II clinical data demonstrated that VYVANSE provided consistent time to maximum concentration of d-amphetamine from patient to patient. Both studies were presented today at the annual meeting of the American Psychiatric Association (APA).
