This medical-grade polyester is currently used in teeth guards that kids and adults wear at night, in tiny tubes used to guide the growth of damaged nerve fibers and in surgical sutures. Researchers are also looking at PCL’s potential as an implant to deliver medications directly to the eyes and to tumors and as a scaffold for growing human tissue. PCL may be an ideal package for islet cells, the studies note, because it can be used to create thin, flexible membranes with pores that let in glucose and nutrients, let out insulin and exclude bigger immune-system molecules.
Federal health officials said the most likely source of romaine lettuce contamination is from the Central Coastal growing regions in northern and central California. No common grower, supplier, distributor or brand of romaine lettuce has been identified. Several major romaine lettuce producers have agreed to label products with a harvest date by region, and new […]
In type 2 diabetes, there also is a steady decline of beta cells that adds to the process of elevated blood sugars. Essentially, if someone is resistant to insulin, the body can, to some degree, increase production of insulin and overcome the level of resistance. After time, if production decreases and insulin cannot be released as vigorously, hyperglycemia develops.
In gastroesophageal reflux disease (GERD), sometimes called heartburn, stomach acid and partially undigested food move backward through the esophagus, escaping from the stomach and through the esophageal sphincter that normally prevents such backsliding. This can occur as a symptom of gastroparesis, says Hiroshi Mashimo, MD, PhD, a gastroenterologist at Harvard Medical School. “If the stomach doesn’t empty, it’s likely to reflux up,” he says. GERD may also result from diabetes-related nerve damage affecting the esophageal sphincter, Mashimo adds. One caution: Some diseases, such as a yeast infection in the esophagus, can masquerade as GERD, so don’t brush off symptoms. We can’t treat the gastroparesis or esophageal sphincter problems that contribute to GERD, but antacids and other medications can help to reduce or neutralize stomach acids (see “PPIs the Right Way,” below).
Type 2 diabetes, a form of diabetes mellitus, is likely one of the better-known chronic diseases in the world — and that's no surprise. Data from the Centers for Disease Control and Prevention suggest in the United States alone, 30.3 million people, or 9.4 percent of the U.S. population, has diabetes, and the majority of these people have type 2.

Exercise is often one of the best treatments for pain. Responding to an entry on pain in the Diabetes Self-Management blog, a Canadian man with Type 2 diabetes reported, “I have cured my back pain completely since starting weight-lifting exercises 18 months ago. I do horizontal and inclined bench presses. I started with 50 lbs and built to 150 lbs. The benches provide complete back support.”
Oskar Minkowski and Joseph Von Mering met accidently in a library in 1889. Striking up a conversation, they began to debate whether the pancreas helped digest and absorb fats. Performing a pancreatectomy on a dog that same night, they found the dog developed glycosuria, a condition associated with diabetes that causes the production of a lot of urine. Minkowski found the urine was 12% sugar. They then depancreatized another dog and found that prevented hyperglycemia.
Big pharma are in the early stages of developing their own cell therapy approaches for diabetes. Novo Nordisk, one of the largest providers of diabetes treatments, is bidding for stem cells and an encapsulation device, stating that the first clinical trial could take place in the “next few years.” Sanofi, also a big name in diabetes, is working with the German Evotec in a beta cell replacement therapy for diabetics.
Low blood sugar (hypoglycemia) is common in people with type 1 and type 2 DM. Most cases are mild and are not considered medical emergencies. Effects can range from feelings of unease, sweating, trembling, and increased appetite in mild cases to more serious effects such as confusion, changes in behavior such as aggressiveness, seizures, unconsciousness, and (rarely) permanent brain damage or death in severe cases. Moderately low blood sugar may easily be mistaken for drunkenness; rapid breathing and sweating, cold, pale skin are characteristic of low blood sugar but not definitive. Mild to moderate cases are self-treated by eating or drinking something high in sugar. Severe cases can lead to unconsciousness and must be treated with intravenous glucose or injections with glucagon.
In another study, albeit including only 30 people, those who were recently diagnosed and went on a very low-calorie diet for eight weeks experienced remission. That remission continued more than six months after their low-calorie diet ended. In people who have had type 2 diabetes for a long time, unfortunately, weight loss has a much more limited impact.
If the amount of insulin available is insufficient, or if cells respond poorly to the effects of insulin (insulin insensitivity or insulin resistance), or if the insulin itself is defective, then glucose will not be absorbed properly by the body cells that require it, and it will not be stored appropriately in the liver and muscles. The net effect is persistently high levels of blood glucose, poor protein synthesis, and other metabolic derangements, such as acidosis.
Type 1 diabetes is caused by an autoimmune reaction (the body attacks itself by mistake) that stops your body from making insulin. About 5% of the people who have diabetes have type 1. Symptoms of type 1 diabetes often develop quickly. It’s usually diagnosed in children, teens, and young adults. If you have type 1 diabetes, you’ll need to take insulin every day to survive. Currently, no one knows how to prevent type 1 diabetes.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
