For years, scientists have tried to determine the basis for discrepancies between race and the predisposition for development of diseases such as type II diabetes and cardiovascular disease. Could factors such as differences in lifestyle or access to health care play a role, or is there something else in play? http://www.physorg.com/news179556345.html Medicine & Health Wed, 09 Dec 2009 05:00:01 EST news179556345 After one year, a low-calorie, low-fat diet appears more beneficial to dieters' mood than a low-carbohydrate plan with the same number of calories, according to a report in the November 9 issue of Archives of Internal Medicine. http://www.physorg.com/news177010219.html Medicine & Health Mon, 09 Nov 2009 18:00:04 EST news177010219 One of the many reasons to pick a low-calorie, low-fat diet rich in vegetables, fruits, and fish is that a host of epidemiological studies have suggested that such a diet may delay the onset or slow the progression of Alzheimer's disease (AD). Now a study published in BioMed Central's open access journal Molecular Neurodegeneration tests the effects of several diets, head-to-head, for their effects on AD pathology in a mouse model of the disease. Although the researchers were focused on triggers for brain plaque formation, they also found that, unexpectedly, a high protein diet apparently led to a smaller brain. http://www.physorg.com/news175287346.html Medicine & Health Tue, 20 Oct 2009 19:57:08 EST news175287346 (PhysOrg.com) -- A strain of yeast that thrives on turning sugar cane into ethanol for biofuel has had its genome completely sequenced by researchers at Duke University Medical Center. http://www.physorg.com/news174073888.html Biology Tue, 06 Oct 2009 18:52:08 EST news174073888 (PhysOrg.com) -- Even as low-carbohydrate/high-protein diets have proven successful at helping individuals rapidly lose weight, little is known about the diets' long-term effects on vascular health. http://www.physorg.com/news170346116.html Medicine & Health Mon, 24 Aug 2009 15:22:37 EST news170346116 Pathogen recognition is the foundation of the body's immune response and survival against infection. A small cell-receptor protein called DC-SIGN is part of the immune system, and recognizes certain pathogens, including those responsible for Ebola, Dengue fever and HIV. How the molecule binds to pathogens has been unclear. http://www.physorg.com/news166785602.html Chemistry Tue, 14 Jul 2009 10:30:01 EST news166785602 (PhysOrg.com) -- Dental disease may be a wake-up call that your diet is harming your body. http://www.physorg.com/news166373895.html Medicine & Health Thu, 09 Jul 2009 15:58:50 EST news166373895 With rising ozone levels scientists have found that high ozone conditions cause a 30 percent decrease in yield and an increase in the concentration of a group of compounds with toxic effects to livestock, but anticarcinogenic effects for humans, within oilseed rape plants. Maarten de Bock will present his findings at the Society for Experimental Biology meeting on Monday, June 29. http://www.physorg.com/news165474218.html Biology Mon, 29 Jun 2009 07:10:01 EST news165474218 A fundamental question about how sugar units are strung together into long carbohydrate chains has also pinpointed a promising way to target new medicines against tuberculosis. http://www.physorg.com/news164910149.html Medicine & Health Mon, 22 Jun 2009 18:10:04 EST news164910149 A modest reduction in the amount of carbohydrates eaten, without calorie restriction and weight loss, appears to increase a sense of fullness, which may help people eat less, a preliminary study found. http://www.physorg.com/news163911999.html Medicine & Health Thu, 11 Jun 2009 04:06:49 EST news163911999 Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center. http://www.physorg.com/news162563042.html Medicine & Health Tue, 26 May 2009 13:24:41 EST news162563042 A Boston University-led research team has identified the structural underpinnings of a widely-known enzyme -- acetoacetate decarboxylase (AADase) -- that was first described correctly more than 43 years ago including how it accelerates its target reaction. Until now it has never been fully explained how the reactions occur in the environment of the cell. http://www.physorg.com/news162044237.html Chemistry Wed, 20 May 2009 13:18:09 EST news162044237 Moderate calorie restriction causes temporal changes in the liver and skeletal muscle metabolism, whereas moderate weight loss affects muscle, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. In addition, researchers found that short-term calorie restriction (CR) with a low-carbohydrate diet caused a greater change in liver fat content and metabolic function than short-term CR with a high-carbohydrate diet. http://www.physorg.com/news160675334.html Medicine & Health Mon, 04 May 2009 17:02:42 EST news160675334 Men and women who chewed Extra(R) sugar-free gum three times hourly in the afternoon chose and consumed less snacks and specifically, less sweet snacks than they did when they did not chew gum. They still reached for a variety of snacks provided but the decrease in overall snack intake was significant at 40 calories and sweet snack intake specifically was significantly lowered by 60 calories. http://www.physorg.com/news159372266.html Medicine & Health Sun, 19 Apr 2009 15:04:59 EST news159372266 Runners clutching bottles of energy drink are a common sight, and it has long been known that sugary drinks and sweets can significantly improve athletes' performance in endurance events. The question is how? http://www.physorg.com/news158993357.html Medicine & Health Wed, 15 Apr 2009 06:00:15 EST news158993357 Carbohydrates are part of our daily vocabulary. We all know they're part of a healthy diet. We know they're in breads and pastas. We know they have something to do with starches and sugars. But, even though carbohydrates are so familiar, there's still a lot for science to learn about them. http://www.physorg.com/news157818037.html Chemistry Wed, 01 Apr 2009 15:21:55 EST news157818037 Scientists from Germany today reported a major advance toward opening the doors of a carbohydrate-based medicine chest for the 21st Century. Much more than just potatoes and pasta, these carbohydrates may form the basis of revolutionary new vaccines and drugs to battle malaria, HIV, and a bevy of other diseases. http://www.physorg.com/news156953765.html Chemistry Sun, 22 Mar 2009 15:17:02 EST news156953765 My friend's teen daughter Kaitlyn commented on the meals she and her brother Ben had on a recent outdoor excursion with their uncle and cousins... all males. http://www.physorg.com/news151331995.html Medicine & Health Fri, 16 Jan 2009 12:39:55 EST news151331995 In a six-month comparison of low-carb diets, one that encourages eating carbohydrates with the lowest-possible rating on the glycemic index leads to greater improvement in blood sugar control, according to Duke University Medical Center researchers. http://www.physorg.com/news150397364.html Medicine & Health Mon, 05 Jan 2009 17:02:44 EST news150397364 Sports drinks containing protein are better at improving athletes' performance.
