wound healing

Harnessing ‘smell’ to heal skinOlfactory receptors in the nose that allow us to smell are also present on the surface of keratinocytes. According to new research, stimulating a particular receptor with a specific synthetic sandalwood oil causes those keratinocytes to proliferate and migrate, processes that are essential to wound healing and skin regeneration.
PODCAST: Strategies for managing leg ulcersLeg ulcers are a common and difficult management problem for all dermatologists. Robert Kirsner, M.D., professor and vice chairman, dermatology, University of Miami Miller School of Medicine, director of the University of Miami Hospital Wound Center, elucidates the diagnosis and management of these challenging skin problems.
Researchers ID protein involved in wound healing, tumor growthA protein that plays a role in healing wounds and in tumor growth could be a future therapeutic target, recent research suggests.
Pediatric woundcare requires collaboration in hospital, communityPediatric woundcare differs from adult woundcare, and that principle should guide what clinicians do in the community setting and in hospitals, according to clinicians speaking at a pediatric woundcare symposium.
In wound healing, standard treatments may still be bestAn analysis of 60 papers related to skin ulcer treatment suggests that the research presented in the majority of the papers is flawed, leading to unreliable results.
Skin cells build ‘bridges’ during wound healingNew research indicates that outer skin cells are able to unite to form a bridge during wound healing. The finding may lead to advances in tissue engineering, artificial skin design and improved wound treatment.
Fractional skin grafting techniques yield big resultsInnovative wound-healing techniques born at the Wellman Center for Photomedicine use simple technologies to capitalize on the skin’s capacity to heal after fractional injury. Devices under development — and one that’s commercially available — make multitudinous miniscule skin grafts that physicians are using to treat burns, chronic wounds and other skin problems without creating scars at tissue donor sites.
New modalities revolutionize chronic wound managementNew therapeutic modalities such as bioactive extracellular matrices, laser therapy and others have revolutionized the treatment and management of chronic wounds, allowing clinicians to achieve much faster wound closures in their patients.
Federal agency funds promising burn treatmentThe Biomedical Advanced Research and Development Authority (BARDA) has awarded a contract to Novan Therapeutics to develop a topical nitric-oxide-based burn therapy.
Scientists ID ‘first responders’ in wound healingResearchers have identified a specific type of T cell that summons other immune cells to the site of skin injuries, shedding light on how these “first responders” contribute to wound healing.
