VBI research offers potential route to diabetes therapeutics

Researchers at VBI have identified a potential target for inhibiting excessive glucose production in type 2 diabetics by modulating the activity of key enzyme phosphoenolpyruvate carboxykinase. This approach could lead to the development of novel therapeutics to slow down but not eliminate glucose overproduction.

New fat, same old problem with an added twist?

A new study conducted at Brandeis University and Malaysia found that a modified fat replacing trans fat causes an increase in blood glucose levels and depresses insulin in humans. The researchers discovered that this interesterified fat had a similar impact on cholesterol levels as trans fat, but with weaker effects.

Research yields new insights into the cause of diabetes

A new hypothesis proposes that a deficiency in the enzyme Pancreatic Endoplasmic Reticulum Kinase (PERK) during fetal development can lead to permanent neonatal diabetes. The research found that PERK-deficient mice have impaired beta cell proliferation, differentiation, and clustering, resulting in reduced insulin production.

Findings by Einstein scientists reveal possible strategy against obesity, diabetes and infertility

The study suggests a novel approach for duplicating leptin's actions when the body no longer responds to the hormone. STAT3 production is essential for leptin's best-known action: acutely reducing food intake. Activating STAT3 may allow normalizing appetite and producing health benefits for obesity, diabetes and infertility.

National survey estimates prevalence of type 2 diabetes among adolescents

A national survey found that approximately 134,071 US adolescents have type 2 diabetes, with 39,005 having the condition and 2,769,736 having impaired fasting glucose levels. The study suggests a significant public health concern among this age group due to the high conversion rate from impaired glucose tolerance to type 2 diabetes.

Cinnamon, cloves improve insulin function, lower risk factors for diabetes, cardiovascular disease

Researchers discovered that consuming cinnamon improves insulin function, lowers glucose and lipid levels. Cloves also showed similar benefits for people with type 2 diabetes. The studies suggest that these spices may be useful in preventing or mitigating cardiovascular disease and other conditions related to inflammation.

Endocrinologist-directed intervention aimed at primary care physicians improves diabetes care

A study found that feedback on performance given to primary care physicians decreased clinical inertia and improved glucose levels in their patients. The intervention, which included physican-specific feedback and computerized reminders, led to sustained improvements in physician behavior and patient outcomes after three years.

How protein-rich diets curb hunger

A study of rats reveals that protein-enriched diets induce glucose synthesis in the small intestine, which is sensed by the liver and brain, ultimately leading to a decline in food consumption. This finding suggests that glucose metabolism in the small intestine may be a new target for treating food intake disorders.
