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.

Researchers discover molecular pathway in blood vessels that controls blood pressure and vascular function

University of Iowa researchers have identified a molecular pathway in blood vessels that controls blood pressure and vascular function and may help explain why certain drugs for type II diabetes also appear to lower patients' blood pressure.

New potential drug target for atherosclerosis

A nuclear receptor protein, known for controlling the ability of cells to burn fat, also exerts powerful anti-inflammatory effects in arteries, suppressing atherosclerosis in mice prone to developing the harmful plaques, according to new research by scientists at the Salk Institute for Biological Studies and the Harvard School of Public Health.

Genetic mutations involved in IGF-I signaling pathway influence life span

Mutations in genes governing an important cell-signaling pathway influence human longevity, scientists at the Albert Einstein College of Medicine of Yeshiva University have found.

Research in diabetes surgery suggests origins of disease

Growing evidence shows that surgery may effectively cure Type 2 diabetes -- an approach that not only may change the way the disease is treated, but that introduces a new way of thinking about diabetes.

Drinking black tea might help combat type 2 diabetes

In an unexpected discovery Scottish scientists have found that black tea may help combat type 2 diabetes, the most common form of the disease.

Low-fat better than low-carb diets for heart health

Low-fat diets are more effective in preserving and promoting a healthy cardiovascular system than low-carbohydrate, Atkins'-like diets, according to a new study by researchers at the Medical College of Wisconsin in Milwaukee.

Intensive insulin therapy may be harmful to the critically ill

Doubt has been cast over the current practice of administering intensive insulin therapy to all critically ill patients, according to a study published this week in the open access journal Critical Care. In certain groups of patients it could even be harmful.

Effect of tumor necrosis factor a inhibitors on heart failure risk in rheumatoid arthritis

A chronic autoimmune disease, rheumatoid arthritis (RA) is characterized by persistent inflammation of the synovial membrane and progressive joint destruction.

Restricting insulin doses increases mortality risk in women with type 1 diabetes

A new study led by researchers at the Joslin Diabetes Center has found that women with type 1 diabetes who reported taking less insulin than prescribed had a three-fold increased risk of death and higher rates of disease complications than those who did not skip needed insulin shots.

Overweight Hispanic children shown to have vascular inflammation

Overweight Hispanic children with normal blood glucose (sugar) levels showed elevated markers for blood vessel inflammation that may predispose them to developing both type 2 diabetes and cardiovascular disease, says a new study led by researchers from the Joslin Diabetes Center.

Hormones produced by the heart eliminate pancreatic cancer in mice

Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).

Spinal cord injury may not increase risk of heart disease

Americans who live with spinal cord injury do not appear to be at greater risk of developing carbohydrate and lipid disorders such as insulin resistance, diabetes, impaired glucose tolerance, and high or low blood cholesterol levels - risk factors for heart disease - than able-bodied persons, according to a new evidence review by HHS' Agency for Healthcare Research and Quality.

Novel link between excessive nutrient levels and insulin resistance

For quite some time now, scientists suspected the so-called hexosamine pathway - a small side business of the main sugar processing enterprise inside a cell - to be involved in the development of insulin resistance.
