Wound Care

A Purdue University engineer’s patent-pending invention could improve the quality of life for millions of people suffering from diabetic foot ulcers. Rahim Rahimi, an assistant professor in the School of Materials Engineering, has developed a flexible polymer composite microneedle array that can overcome the physicochemical bacterial biofilm present in chronic, nonhealing wounds and deliver both

A University of California, Irvine-led study identifies a new molecular pathway that promotes the healing of wounds in the skin. Titled, “GRHL3 activates FSCN1 to relax cell-cell adhesions between migrating keratinocytes during wound reepithelialization,” the study was published today in JCI Insight. The molecular pathway identified is controlled by an evolutionary conserved gene called a

Natural killer cells do not just kill cancer cells or cells infected with viruses, they also mediate a trade-off between wound healing and bacterial defense in skin wounds. If the healing process is accelerated, the immune defense is weakened, researchers at the University of Zurich have now shown. This has relevance in treating skin injuries

Throughout the COVID-19 pandemic, clinicians have noted that certain patients are at especially high risk of developing severe illness or dying from coronavirus infection. Type 2 diabetes — a condition affecting more than 10 percent of the U.S. population — is one of the main risk factors for severe COVID-19 illness. New research from U-M

A significant cross-government effort is underway, dubbed ‘Operation Warm Welcome’, to ensure Afghans arriving in the UK receive the vital support they need to rebuild their lives, find work, pursue education and integrate into their local communities. As part of the New Plan for Immigration, the government announced that those coming to the UK through

Light therapy may accelerate the healing of burns, according to a University at Buffalo-led study. The research, published in Scientific Reports, found that photobiomodulation therapy — a form of low-dose light therapy capable of relieving pain and promoting healing and tissue regeneration — sped up recovery from burns and reduced inflammation in mice by activating

Today, the U.S. Food and Drug Administration announced participation in several new collaborative communities aimed at addressing challenges in patient health care. Collaborative communities are a continuing forum where private and public sector representatives of the community work together on medical device challenges to achieve common objectives and outcomes. We’re pleased to announce the progress

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 fibres that give structure to connective tissue such as skin, tendons, cartilage and bones. Researchers at ETH Zurich have now developed a multi-component molecule that interacts with collagen and can

Customized, biomedically applicable materials based on tropoelastin are being developed in a joint project by Skinomics GmbH from Halle, Martin Luther University Halle-Wittenberg and the Fraunhofer Institute for Microstructure of Materials and Systems IMWS. The material combines biocompatibility, durability, biodegradability and favorable mechanical properties similar to those of skin. Preclinical tests have confirmed that it

Tens of millions of patients around the world suffer from persistent and potentially life-threatening wounds. These chronic wounds, which are also a leading cause of amputation, have treatments, but the cost of existing wound dressings can prevent them from reaching people in need. Now, a Michigan State University researcher is leading an international team of

A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process. The healing process of the tissues in the human body is particularly well-studied in skin, especially as skin serves as a layer of protection from the environment. However,
