Insulin News and Research

RSS

Insulin is a hormone that is needed to convert glucose, starches and other food into energy needed for daily life. Insulin allows cells to use glucose for fuel and is secreted by beta cells in the islets of Langerhans. The release of insulin from the pancreas is stimulated by increased blood glucose, vagal nerve stimulation, and other factors. Insulin is obtained from various animals and available in a variety of preparations. Commercial insulin preparations differ in a number of ways, including differences in the animal species from which they are obtained; their purity, concentration, and solubility; and the time of onset and duration of their biologic action. An oral hypoglycemic agent is not a form of insulin therapy.

Diabetes drug improves metabolic changes associated with HIV combination therapy

Use of an oral antidiabetes medication produced significant improvement in a group of patients with HIV lipodsytrophy, a syndrome involving the redistribution of fat and other metabolic changes in those receiving combination drug therapy for HIV infection.

Studies identify risk factors for colon cancer in women

In new studies presented today at Digestive Disease Week in New Orleans, scientists report that women’s preferences for a female physician may delay or prevent proper colorectal screenings due to a lack of females in the field and diabetes may be a significant risk factor for development of colon cancer.

Exercise reverses signs of artery disease in obese children

Healthy but obese adolescents display abnormal responses to tests of blood vessel function, but after a short course of exercise their test results match those of lean youngsters, even though they remain heavy, according to a new study in the May 19, 2004 issue of the Journal of the American College of Cardiology.

Small, frequent doses of caffeine best strategy for staying awake

Caffeine is the world's most widely-used stimulant yet, scientists still do not know exactly how it staves off sleep. Researchers at Brigham and Women's Hospital, Harvard Medical School and other institutions have now discovered that caffeine works by thwarting one of two interacting physiological systems that govern the human sleep-wake cycle.

Critical link found between inflammation, heart disease and stroke

Until recently, the story on platelets was pretty simple: tiny blood cells, with limited sophistication because they had no nucleus, and their claim to fame was to be a first-responder to a wound site, to promote healthy clotting and prevent infection.

New patent has potential for the treatment of obesity

Two researchers have announced receipt of a patent on the use of MSH analogs--chemicals that regulate fat storage and metabolism in the body.

Alternative vaccine to Dryvax for smallpox

Not everybody can safely be vaccinated against smallpox using the current FDA-approved vaccine. Scientists hope another study vaccine, now undergoing its first testing in the United States at Saint Louis University, will give a choice to people who can't be given the current vaccine, known as Dryvax®.

Study shows Chromium Picolinate and Biotin Combination significantly lowers coronary risk factors in people with Type 2 Diabetes

Results of a new double-blind, placebo-controlled, randomized clinical study show that daily nutritional supplementation with a combination of chromium picolinate and biotin (marketed as Diachromeä) significantly improved coronary risk factors in people with type 2 diabetes.

New studies put spotlight on replicative capacity of beta cells

Researchers at Harvard University and the Howard Hughes Medical Institute (HHMI) have discovered that insulin-producing beta cells in the pancreas that are attacked in type 1 diabetes are replenished through duplication of existing cells rather than through differentiation of adult stem cells.

First canine insulin drug

FDA has approved a porcine insulin zinc suspension product as the first drug for treating diabetic dogs. Prior to the development of this product, the only treatment veterinarians could use on diabetic dogs was human insulin, which is less compatible with a dog’s metabolic system.

Blood pressure levels on rise among American children and teenagers

Systolic and diastolic blood pressure levels for children and teenagers have risen substantially since 1988, according to a new study supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. The study links part of the rise to a concurrent increase in the prevalence of overweight and obesity.
