Dhaval Bhatt had been warned about hospital emergency rooms. “People always told me to avoid the ER in America unless you are really dying,” said Bhatt, an immigrant from India who got a Ph.D. in pharmacology in the U.S. and is now a research scientist at Washington University in St. Louis. But when Bhatt’s 2-year-old
Although human skin heals from injuries and wounds, many of us have scars that are left behind. Scar formation happens in adult mammals because skin regeneration does not fully occur. This poses a challenge to physicians who wish to conduct surgeries without scars appearing afterwards. In a newly published article in Biomedicines, a team led
Persons experiencing homelessness (PEH) who were at high risk of severe COVID-19 were 2.5 times less likely to contract SARS-CoV-2 if they were provided with individual hotel rooms and medical and social support compared to citywide rates in homeless shelters, according to new research from the University of Chicago Medicine, Lawndale Christian Health Center, and
A Cologne-based research team has discovered that the metabolism of mitochondria, the energy suppliers of cells, in macrophages coordinate wound healing to a significant degree. Macrophages belong to the white blood cells and are also known as scavenger cells. Professor Dr. Sabine Eming and her collaborators and colleagues at the CECAD Cluster of Excellence for
A protein named Agrin has been discovered to promote wound healing and repair, when it is triggered after skin tissue is injured. These findings could pave the way for the development of Agrin protein therapy to accelerate skin tissue healing for chronic wounds from diabetes or burns. The research, led by A*STAR’s Institute of Molecular
Chronic wounds are deep and difficult to repair. Often, the top of the injury heals before the bottom, so the wound collapses in on itself. Over time, this can result in scar tissue and reduced skin function. In APL Bioengineering, by AIP Publishing, researchers from the University of Birmingham and University of Huddersfield developed an
Research from the University of Cincinnati College of Medicine shows that use of a topical drug, called AB569, a combination of acidified nitrite and EDTA (or ethylenediaminetetraacetic acid) promotes killing of antibiotic-resistant bacteria while enhancing the healing of wounds in a variety of burn injuries. The study was published in the journal Infection and Immunity.
New research by RCSI University of Medicine and Health Sciences suggests that effective wound healing may be aided by replicating a crucial component of our blood. The finding, published today in Advanced Functional Materials, was led by researchers at the Tissue Engineering Research Group (TERG) and SFI AMBER Centre based at RCSI’s Department of Anatomy
Smartphone pictures of post-surgical wounds taken by patients and then assessed by clinicians can help with the early identification of infections, a study has found. Researchers discovered these so-called ‘surgery selfies’ were linked with a reduced number of visits to GPs and improved access to advice among patients who took them. The practice could help
Burns are one of the most common injuries suffered by Australians and one of the top causes of death in children under four. While survival rates for burns patients have improved substantially, treating pediatric burns remains challenging, especially with the rise of multi-drug resistant bacteria. Adelaide researchers develop new treatment for serious burns | 7NEWSPlay
PIEZO1, an ion channel mechanosensor found within cells, has been revealed to play a key role in regulating the speed of skin wound healing by researchers at the University of California, Irvine (UCI). Published today in eLife, the study, titled, “Spatiotemporal dynamics of PIEZO1 localization controls keratinocyte migration during wound healing,” found that in mice
Ischemia, which in modern Latin means, “staunching of blood,” is a medical condition in which the blood supply is cut off to different parts of the body. In patients who are bed-ridden, ischemia can manifest as pressure ulcers. Else, it could be the Raynaud’s phenomenon in someone under severe stress. This condition can be rescued
The Institute of Skin Integrity and Infection Prevention (ISIaIP) at Huddersfield has signed a memorandum of understanding with the Regional Hospital Wiener Neustadt that will create a satellite office of the ISIaIP south of the Austrian capital Vienna. The alignment will enable joint research projects, international teaching and more publications. The two institutions have collaborated
How can doctors make sure a dressed wound is healing without taking off the bandage? This is a conundrum, because removing a bandage can disrupt the healing process. Technology presented in a new study in open-access journal Frontiers in Physics could help. This new ‘smart bandage’ contains a sensor that can very sensitively measure wound
Lipopolysaccharide, a virulence factor produced by bacteria, is a toxin that can cause a systemic inflammation via the circulation. In a recently completed study, genetic markers were discovered which are associated with a heightened lipopolysaccharide level in the blood. Microbes are part of the human body, and bacteria or their components often end up in
A research team led by Professor Lim Chwee Teck from the National University of Singapore’s (NUS) Department of Biomedical Engineering and Institute for Health Innovation & Technology (iHealthtech), in collaboration with clinical partners from Singapore General Hospital, has developed a smart wearable sensor that can conduct real-time, point-of-care assessment of chronic wounds wirelessly via an
Although sometimes hard to accept, with aging, many things in our bodies change. One of these is the ability of the skin to regenerate. Old skin is just not as good as young skin at healing wounds. However, the molecular and cellular mechanisms underlying this are largely unknown. Now, researchers from Japan have identified a
In the fight against multidrug-resistant bacteria, scientists in Sweden have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body’s own immune responses to fight infections. Reporting in the Journal of the American Chemical Society, researchers from KTH Royal Institute of Technology, Karolinska Institutet and Karolinska University Hospital

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
