COLUMBIA, Mo. – In a first study of its kind study, researchers have found that a common chemical consumers are exposed to several times a day may be altering insulin release. Results of the study, led by scientists at the University of Missouri, indicate that the Food and Drug Administration-approved “safe” daily exposure amount of BPA may be enough to have implications for the development of Type 2 diabetes and other metabolic diseases.(more…)
Researchers at Yale School of Medicine have pinpointed a mechanism in part of the brain that is key to sensing glucose levels in the blood, linking it to both type 1 and type 2 diabetes. The findings are published in the July 28 issue of Proceedings of the National Academies of Sciences.
“We’ve discovered that the prolyl endopeptidase enzyme — located in a part of the hypothalamus known as the ventromedial nucleus — sets a series of steps in motion that control glucose levels in the blood,” said lead author Sabrina Diano, professor in the Departments of Obstetrics, Gynecology & Reproductive Sciences, Comparative Medicine, and Neurobiology at Yale School of Medicine. “Our findings could eventually lead to new treatments for diabetes.” (more…)
A new study reports that the small intestine uses more cells than scientists had realized to absorb microspheres large enough to contain therapeutic protein drugs, such as insulin. The finding in rats, published in the Proceedings of the National Academy of Sciences, is potentially good news for developing a means for oral delivery of such drugs.
PROVIDENCE, R.I. [Brown University] — The small intestine employs more cells and mechanisms than scientists previously thought to absorb relatively large particles, such as those that could encapsulate protein-based therapeutics like insulin, according to a new study. The findings, published the week of Aug. 5, 2013, in the Proceedings of the National Academy of Sciences, open another window for drug makers to increase absorption of medicines taken by mouth.

In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the University of North Carolina at Chapel Hill, the Massachusetts Institute of Technology and Children’s Hospital Boston.
“We’ve created a ‘smart’ system that is injected into the body and responds to changes in blood sugar by releasing insulin, effectively controlling blood-sugar levels,” says Dr. Zhen Gu, lead author of a paper describing the work and an assistant professor in the joint biomedical engineering program at NC State and UNC Chapel Hill. “We’ve tested the technology in mice, and one injection was able to maintain blood sugar levels in the normal range for up to 10 days.” (more…)
For someone who is dealing with type 2 diabetes, managing diet, exercise, medication and blood sugar levels on a regular basis is key to managing the disease. For someone with type 2 diabetes, keeping blood sugar levels on track over the long term is about more than just taking insulin or medication. This individual will also have to balance good nutrition choices with ample physical activity, and will have to make other smart health choices on a daily basis in order to achieve the best possible results.
Managing this disease is all about striking up a balance between all of the elements involved. One cannot simply eradicate carbohydrates from the diet and hope for the best.
1. Establish a health care team. Treating and managing this disease will require the assistance of numerous health care professionals over time. Any health care provider who works to help a patient care for their diabetes is on this care team, which may include a general practitioner, endocrinologist, nurses, dieticians, nutritionist, pharmacist, educators, eye doctors and podiatrists.

UCLA stem cell researchers have shown that insulin and nutrition prevent blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory response and blood development in response to dietary changes in humans.
Keeping blood stem cells, or progenitor cells, from differentiating into blood cells is important as blood stem cells are needed to create the blood supply for the adult fruit fly.(more…)
EAST LANSING, Mich. — Research by a team of Michigan State University scientists has shed new light on why some body parts are more sensitive to environmental change than others, work that could someday lead to better ways of treating a variety of diseases, including Type-2 diabetes.
The research, led by assistant zoology professor Alexander Shingleton, is detailed in the recent issue of the Proceedings of the Library of Science Genetics. (more…)
