About one-fourth of people with diabetes develop painful foot ulcers, which are slow to heal due to low oxygen in the wound from impaired blood vessels and increased inflammation. These wounds can become chronic, leading to poor quality of life and potential amputation. Representative images of wounds treated with or without gel and oxygen-release microspheres...

Alongside helping to detect tumors, the molecule could play a significant role in the research of wound healing disorders. Collagen is the most abundant protein in the human body. It makes up a third of protein content and single strands assemble to form stable fibers that give structure to connective tissue such as skin, tendons, cartilage,...

Scientists there have now developed...
AMERICAN INSTITUTE OF PHYSICS IMAGE: Biomedical engineers have developed a technique to observe wound healing in real time, discovering a central role for cells known as fibroblasts. The work is the first demonstration of a wound closure model within human vascularized tissue in a petri dish. This image shows steps in wound healing in a...
by Osaka University Most tissues of the body have the extraordinary ability to heal themselves upon injury. But sometimes something goes awry during the complex process of wound healing and the tissue forms too much connective tissue, also called fibrosis, around the injured area, which can result in the organ not functioning properly. Now, researchers...
Nick Lavars Today’s bandages are pretty good at covering up wounds, sealing them off from infectious bacteria and allowing the body to go to work patching up the damage. But could there come a time when bandages play more of an active role in accelerating healing and fighting infection, so we can peel them off...
By Jayne Leonard Reviewed by Alana Biggers, MD, MPH A wound infection occurs when germs, such as bacteria, grow within the damaged skin of a wound. Symptoms can include increasing pain, swelling, and redness. More severe infections may cause nausea, chills, or fever. A person may be able to treat minor wound infections at home. However, people with more severe or persistent wound infections should...
October 25, 2018–(BRONX, NY)–By incorporating a gene-suppressing drug into an over-the-counter gel, researchers at Albert Einstein College of Medicine and their colleagues cut healing time by half and significantly improved healing outcomes compared to control treatments. Results from the combination therapy, which was tested in mice, were published online today in Advances in Wound Care....
A new study shows that e-cigarette vaping negatively affects skin wound healing, causing damage similar to that of traditional cigarette smoking. Researchers, led by a team from Boston Medical Center (BMC), found exposure to both e-cigarette vaping and traditional cigarettes in experimental models resulted in increased tissue death, which delays wound healing. These findings, published...
