One way diabetes is bad for your blood vessels is by creating too much competition for an amino acid that helps blood vessels relax, researchers say.
That amino acid, L-arginine, is broken down by the enzyme arginase to urea, which helps the body eliminate toxins resulting from the proteins we eat. Diabetics have a lot of arginase activity, which means they use a lot more L-arginine, says Dr. Maritza Romero, postdoctoral fellow at the Medical College of Georgia and lead author of the paper published in the current issue of Circulation Research.
It also means too little L-arginine is available to help nitric oxide synthase make nitric oxide, the powerful vasodilator that helps blood vessels relax, says Dr. Romero, who works in the lab of Dr. R. William Caldwell, chair of the MCG Department of Pharmacology and Toxicology and the study's corresponding author.

Why do some people solve problems more creatively than others? Are people who think creatively somehow different from those who tend to think in a more methodical fashion?
These questions are part of a long-standing debate, with some researchers arguing that what we call "creative thought" and "noncreative thought" are not basically different. If this is the case, then people who are thought of as creative do not really think in a fundamentally different way from those who are thought of as noncreative. On the other side of this debate, some researchers have argued that creative thought is fundamentally different from other forms of thought. If this is true, then those who tend to think creatively really are somehow different.
A new study led by John Kounios, professor of psychology at Drexel University and Mark Jung-Beeman of Northwestern University addresses these questions by comparing the brain activity of creative and noncreative problem solvers. The study published in the journal Neuropsychologia, reveals a distinct pattern of brain activity, even at rest, in people who tend to solve problems with a sudden creative insight -- an "Aha! Moment" - compared to people who tend to solve problems more methodically.

Adults with allergy symptoms report a high incidence of Irritable Bowel Syndrome (IBS), suggesting a link between atopic disorders and IBS according to a study published this month in Annals of Allergy, Asthma & Immunology,the scientific journal of the American College of Allergy, Asthma and Immunology.

Minneapolis, MN. - With the start of the new year, millions of Americans have resolved to lie less, cheat less, put the holiday hangovers behind them, or otherwise better their lives. Some will moderate their bad habits; others may make significant changes and become shining examples of integrity. But most of those well-intended New Year's resolutions are destined to fail. In an age where cheating scandals plague elite universities and major corporations are brought down by unethical actions, the debate about the origins and nature of our decisions plays into a larger debate about genetic determinism and free will.
