Smart LED Contact Lenses for Treating Diabetic Retinopathy

Diabetes is a long-term chronic disease with many complications and requires care over a lifetime. The longer a patient suffers from diabetes, the higher the risk of developing retinopathy which can progressively lead to a decline in vision and even to blindness.

A POSTECH research team led by Professor Sei Kwang Hahn and Ph.D. candidate Geon-Hui Lee (Department of Materials Science and Engineering) in collaboration with Dr. Sangbaie Shin of PHI BIOMED Co. has recently developed a smart contact lens-type wearable device to prevent diabetic retinopathy and treat it in its early stages by irradiating 120 µW far red/LED light to the retina. This technology for smart LED contact lens has attracted a great attention for various ophthalmologic diseases.

Diabetic retinopathy is curren...

Treating Tough Tumors by exploiting their Iron ‘Addiction’

Researchers at the University of California, San Francisco, have successfully leveraged an FDA-approved drug to halt growth of tumors driven by mutations in the RAS gene, which are famously difficult to treat and account for about 1 in 4 cancer deaths.

Taking advantage of what they discovered to be the cancer cells’ appetite for a reactive form of iron, the researchers tweaked an anticancer drug to operate only in these iron-rich cells, leaving other cells to function normally...

Novel Treatment makes Pancreatic Cancer Susceptible to Immunotherapy, mouse study shows

New research from Washington University School of Medicine in St. Louis shows that blocking a major inflammatory pathway in pancreatic cancer makes the tumors sensitive to chemotherapy and a type of immunotherapy that helps the immune system’s T cells to attack cancer cells. Above, pancreatic cancer cells are shown in green. T cells are in red.

Washington University to lead national clinical trial investigating therapy. A new study – in mice – suggests that blocking a major inflammatory pathway that is activated in pancreatic cancer makes the tumors sensitive to chemotherapy and a type of immunotherapy that prompts the immune system’s T cells to attack the cancer cells. The therapy more than doubled survival in a mouse model of pancreatic cancer.

Pancreatic cancer is one of the most...

More Alcohol, Less Brain: Association begins with an average of just one drink a day

Even light-to-moderate drinking is associated with harm to the brain, according to a new study. Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day — the equivalent of about half a beer — and rises with each additional drink.

The research, using a dataset of more than 36,000 adults, revealed that going from one to two drinks a day was linked with changes in the brain equivalent to aging two years. Heavier drinking was associated with an even greater toll. The science on heavy drinking and the brain is clear: The two don’t have a healthy relationship...
