Invention could accelerate tissue growth compared with current treatment. A hydrogel invented at Rice University that is adept at helping the body heal may also be particularly good at treating wounds related to diabetes. The Rice lab of chemist and bioengineer Jeffrey Hartgerink reported this week that tests on diabetic animal models showed the injectable hydrogel significantly accelerated wound healing compared with another hydrogel often used in clinics. The study appears this week in the American Chemical Society journal ACS Biomaterials Science and Engineering...

U.S. Army-funded researchers at Brandeis University have discovered a process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue. The breakthrough material may lead to autonomous soft robotics, dual sensors and actuators for soft exoskeletons, or artificial skins. The research lays the foundations for futuristic soft active matter with highly distributed and tightly integrated sensing, actuation, computation and control, said Dr...

Researchers helped develop a specially engineered retinal patch to treat people with sudden, severe sight loss. In July 2015, 86-year-old Douglas Waters developed severe age-related macular degeneration (AMD). He struggled to see things clearly, even when up close. A few months later, he became part of a clinical trial that used stem cell-derived ocular cells developed in part by researchers at UC Santa Barbara. His retinal eyepatch was implanted at Moorfields Eye Hospital, a National Health Service (NHS) facility in Waters’ hometown of London, England.

In the months before Waters’ surgery, his vision was poor and he ...

High Omega-6 Levels can Protect Against Premature Death

Serum n–6 polyunsaturated fatty acids and risk of death: the Kuopio Ischaemic Heart Disease Risk Factor Study. The American Journal of Clinical Nutrition, 2018; 107 (3): 427 DOI: 10.1093/ajcn/nqx063

Could omega-6 fatty acids protect you against premature death? The answer is yes, according to a new University of Eastern Finland study. While protecting against death, omega-6 fatty acids also keep cardiovascular diseases at bay. “Linoleic acid is the most common polyunsaturated omega-6 fatty acid. We discovered that the higher the blood linoleic acid level, the smaller the risk of premature death,” says Adjunct Professor Jyrki Virtanen from the University of Eastern Finland, reporting the findings in the American Journal of Clinical Nutrition.

Although omega-6 polyunsaturated fatty acids a...
