Receptor may aid spread of Alzheimer’s and Parkinson’s in brain

Posted: 23 Aug 2013 11:21 AM PDT

Scientists at Washington University School of Medicine in St. Louis have found a way that corrupted, disease-causing proteins spread in the brain, potentially contributing to Alzheimer’s disease, Parkinson’s disease and other brain-damaging disorders.

The research identifies a specific type of receptor and suggests that blocking it may aid treatment of theses illnesses. The receptors are called heparan sulfate proteoglycans (HSPGs).

Single Injection May Revolutionize Melanoma Treatment, Study Shows

Posted: 23 Aug 2013 07:48 AM PDT

A new study at Moffitt Cancer Center could offer hope to people with melanoma, the deadliest form of skin cancer. Researchers are investigating whether an injectable known as PV-10 can shrink tumors and reduce the spread of cancer. PV-10 is a solution developed from Rose Bengal, a water-soluble dye commonly used to stain damaged cells in the eye. Early clinical trials show PV-10 can boost immune response in melanoma tumors, as well as the blood stream.

Gut taste mechanisms are abnormal in diabetes sufferers

Posted: 23 Aug 2013 07:40 AM PDT

Researchers at the University of Adelaide have discovered that the way the gut "tastes" sweet food may be defective in sufferers of type 2 diabetes, leading to problems with glucose uptake.

This is the first time that abnormal control of so-called "sweet taste receptors" in the human intestine has been described by researchers. The work could have implications for a range of health and nutrition problems experienced by diabetes patients.
