But what sets that circadian rhythm? http://www.physorg.com/news173975219.html Medicine & Health Mon, 05 Oct 2009 15:38:32 EST news173975219 Scientists working at Queen Mary, University of London, have developed micrometer-sized capsules to safely deliver drugs inside living cells. http://www.physorg.com/news173681739.html Nanotechnology Fri, 02 Oct 2009 05:56:26 EST news173681739 Treating pregnant women for mild gestational diabetes resulted in fewer cesarean sections and other serious birthing problems associated with larger than average babies, according to a study conducted in part at the University of North Carolina at Chapel Hill. http://www.physorg.com/news173552801.html Medicine & Health Wed, 30 Sep 2009 19:10:06 EST news173552801 Diabetes patients should always control their own blood sugar values if this leads to improvements in their treatment. This is the view advocated by Michael Nauck of the Bad Lauterberg Diabetes Center and his coauthors in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106[37]: 587-94), who discuss sensible approaches to blood glucose self-monitoring. http://www.physorg.com/news173440224.html Medicine & Health Tue, 29 Sep 2009 11:00:04 EST news173440224 Middle-aged male smokers with high cholesterol and blood pressure die, on average, a decade sooner than peers without any of these heart disease risk factors, according to a study published Friday. http://www.physorg.com/news172434199.html Medicine & Health Thu, 17 Sep 2009 19:24:04 EST news172434199 The human body is as mysterious as it is magnificent. For every essential function like thought or a heartbeat, the body exhibits quirky behaviors that seem to defy explanation. Like goose bumps. Or hiccups. Or peals of laughter. http://www.physorg.com/news172157769.html Medicine & Health Mon, 14 Sep 2009 15:30:01 EST news172157769 The latest data from groundbreaking human clinical trials of the effectiveness of continuous glucose monitors (CGM) show that the primary determinant of improvements in achieving better diabetes control is regular use of monitors - six days per week or more - rather than the age of patients, and that benefits continue well past the time when people with type 1 diabetes begin using the devices - including experiencing fewer low blood sugar emergencies. http://www.physorg.com/news171651810.html Medicine & Health Tue, 08 Sep 2009 18:08:40 EST news171651810 Mild glucose intolerance in pregnancy may be an early identifier of women who are at increased risk of heart disease in the future, found a new study http://www.cmaj.ca/press/cmaj090569.pdf published in CMAJ (Canadian Medical Association Journal). http://www.physorg.com/news170341787.html Medicine & Health Mon, 24 Aug 2009 16:40:01 EST news170341787 Rosiglitazone, a drug used to treat type 2 diabetes, is associated with an increased risk of heart failure and death among older patients compared to a similar drug (pioglitazone), concludes a study published on BMJ.com today. http://www.physorg.com/news169985249.html Medicine & Health Thu, 20 Aug 2009 11:30:01 EST news169985249 The Hormone Foundation, the public education affiliate of The Endocrine Society, in collaboration with the National Alliance for Caregiving, today released key findings from a first-of-its-kind survey aimed at better understanding the daily needs and struggles of unpaid caregivers of people with diabetes. http://www.physorg.com/news169818618.html Medicine & Health Tue, 18 Aug 2009 13:20:16 EST news169818618 The team, in collaboration with University Hospital Aintree, the University of Warwick and researchers in Sweden, found that people classified as obese and those with pre-diabetes have raised levels of a protein called SPARC, that can cause tissue scarring. The research revealed that an increase in insulin, a hormone that controls blood sugar levels, and leptin, a hormone that regulates appetite, can trigger an increase in SPARC, which can prevent the proper storage of fat in fat tissue cells. http://www.physorg.com/news169375596.html Medicine & Health Thu, 13 Aug 2009 10:00:08 EST news169375596 Accumulating safety data from the large, international ORIGIN trial have been reviewed by its independent data monitoring committee, who have concluded that there is no cause for concern. http://www.physorg.com/news169201666.html Medicine & Health Tue, 11 Aug 2009 09:40:01 EST news169201666 In findings that add to the prospects of regenerating insulin-producing cells in people with type 1 diabetes, researchers in Europe -- co-funded by the Juvenile Diabetes Research Foundation -- have shown that insulin-producing beta cells can be derived from non-insulin-producing cells in the pancreas. http://www.physorg.com/news168799882.html Medicine & Health Thu, 06 Aug 2009 17:54:39 EST news168799882 Researchers have found a way in mice to convert another type of pancreas cell into the critical insulin-producing beta cells that are lost in those with type I diabetes. The secret ingredient is a single transcription factor, according to the report in the August 7th issue of Cell, a Cell Press journal. http://www.physorg.com/news168788864.html Chemistry Thu, 06 Aug 2009 15:10:01 EST news168788864 A gut hormone first described in 1928 plays an unanticipated and important role in the remote control of blood sugar production in the liver, according to a report in the August 6th Cell Metabolism, a Cell Press publication. What's more, the researchers show that rats fed a high-fat diet for a few days become resistant to the glucose-lowering hormone known as cholecystokinin (CCK). http://www.physorg.com/news168697036.html Medicine & Health Wed, 05 Aug 2009 13:30:01 EST news168697036 Short-term complications and death rates were low following bariatric surgery to limit the amount of food that can enter the stomach, decrease absorption of food or both, according to the Longitudinal Assessment of Bariatric Surgery (LABS-1).

Now, researchers at the Salk Institute for Biological Studies have filled in the gap and identified the missing link between the two. Their findings, to be published in the June 21, 2009 advance online edition of the journal Nature, explain how obesity sets the stage for diabetes and why thin people can become insulin-resistant. http://www.physorg.com/news164810148.html Medicine & Health Sun, 21 Jun 2009 13:36:38 EST news164810148 Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University. http://www.physorg.com/news164538915.html Medicine & Health Thu, 18 Jun 2009 10:20:01 EST news164538915 Researchers at the Harold Hamm Oklahoma Diabetes Center have found a way to stop the damage caused by Type 1 diabetes with the combination of insulin and a common vitamin found in most medicine cabinets. http://www.physorg.com/news163768625.html Medicine & Health Tue, 09 Jun 2009 12:17:27 EST news163768625 Traumatic brain injury - not heart disease, stroke or cancer - is the number one cause of death and disability in people under 45. Each year, some 1.5 million Americans, including soldiers, athletes, the elderly and children, sustain head injuries, and nearly half of them will be hospitalized and treated in an emergency room or intensive care unit. http://www.physorg.com/news163244708.html Medicine & Health Wed, 03 Jun 2009 10:47:46 EST news163244708 Mice lacking the fat hormone leptin or the ability to respond to it become morbidly obese and severely diabetic -not to mention downright sluggish. Now, a new study in the June Cell Metabolism shows that blood sugar control in those animals can be completely restored by returning leptin sensitivity to a single class of neurons in the brain, which account for only a small fraction of those that normally carry the hormone receptors. http://www.physorg.com/news163164889.html Biology Tue, 02 Jun 2009 12:36:37 EST news163164889 (PhysOrg.com) -- People with diabetes who maintain intensive, low blood sugar levels are significantly less likely to suffer heart attacks and coronary heart disease, new research published today in The Lancet has shown. http://www.physorg.com/news162743562.html Medicine & Health Thu, 28 May 2009 15:33:43 EST news162743562 People with diabetes who maintain intensive, low blood sugar levels are significantly less likely to suffer heart attacks and coronary heart disease, new research published today in The Lancet has shown. http://www.physorg.com/news162155287.html Medicine & Health Thu, 21 May 2009 20:09:52 EST news162155287 Scientists in Sydney and Boston believe they may have identified a gene that controls abnormal production of sugar in the liver, a very troublesome problem for people with diabetes. http://www.physorg.com/news162133734.html Medicine & Health Thu, 21 May 2009 14:09:22 EST news162133734 (AP) -- Marketing executives at British drugmaker AstraZeneca PLC for years blocked efforts by company scientists to raise concerns antipsychotic drug Seroquel caused weight gain and other problems, saying that would harm sales, plaintiff lawyers say. http://www.physorg.com/news162041479.html Medicine & Health Wed, 20 May 2009 12:31:43 EST news162041479 Research from the Johns Hopkins Children's Center reveals that the drug most commonly used in type 2 diabetics who don't need insulin works on a much more basic level than once thought, treating persistently elevated blood sugar - the hallmark of type 2 diabetes - by regulating the genes that control its production. http://www.physorg.com/news161527158.html Medicine & Health Thu, 14 May 2009 13:39:55 EST news161527158 (AP) -- People with Type 2 diabetes may soon get a very different treatment approach: A drug that helps control blood sugar via the brain - an idea sparked, surprisingly, by the metabolism of migrating birds. http://www.physorg.com/news160843146.html Medicine & Health Wed, 06 May 2009 15:39:44 EST news160843146
