Around the world, 425 million people live with diabetes and upwards of 15 percent develop foot ulcers, which increases their risk of death 2.5 times. A new nitric oxide-releasing technology has the potential to cut down the healing time of diabetic foot ulcers from 120 days to 21 days.

A groundbreaking new study by UC Davis researchers has uncovered why obesity both fuels cancer growth and allows blockbuster new immunotherapies to work better against those same tumors.

Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities. "This means that eight or nine silicon nanoneedles can be injected into a single cell without significantly damaging a cell. So we can use these nanoneedles to deliver biomolecules into cells or even tissues with minimal invasiveness," said Chi Hwan Lee, an assistant professor at Purdue University.

A study in mice done at IRB Barcelona and CNAG-CRG explains that dermal fibroblasts lose their cell identify over time and with it their capacity to produce and secrete collagen and other proteins.

Researchers at Duke Health, publishing in the Nov. 9 issue of the journal Science, used mouse models to track how immune cells are triggered during anaphylactic shock. They describe a previously unknown mechanism in which a newly identified immune cell basically mines the blood vessels for allergens and then utilizes an unusual mechanism for rapidly delivering the blood-borne allergens to mast cells.
