wound-healing

When people think about healing from a wound, they usually think about medical care, bandages, and good nutrition. But scientists are now learning that the mind and emotions can also play a powerful role in how the body recovers. A recent study by researchers at the Medical University of South Carolina and collaborating institutions has […] The post Loneliness can delay wound healing at genetic l…

This study successfully constructed shikonin-Co nanoparticles (Co-Shik NPs) and systematically evaluated their healing effects on diabetic wounds. The nanoparticles, prepared via a self-assembly method, exhibited uniform particle size and stable structure. In vitro experiments demonstrated that the material showed no cytotoxicity at a concentration of 16 mg/L, significantly scavenged reactive oxy…

Chronic wounds are a serious health problem that affect millions of people around the world. In developed countries, about 2% of the population suffers from wounds that do not heal properly. These wounds can last for months or even years, causing pain, infection, and high medical costs. Current treatments can be expensive and sometimes come […] The post Seaweed could heal wounds naturally, study …

Treating wounds may soon become safer and more precise thanks to a new invention from scientists at Brown University. In a recent study published in the journal Science Advances, researchers developed a special wound dressing that can release antibiotics only when harmful bacteria are present. This new approach could help wounds heal faster while also […] The post Smart bandage releases antibioti…

When nutrients run low, hair follicle stem cells can stop making hair and help repair the skin instead. A drop in the amino acid serine triggers this switch, accelerating wound healing. Human skin relies on two main groups of adult stem cells: epidermal stem cells and hair follicle stem cells. Under normal conditions, each group [...]

Researchers found that a common antibiotic-resistant bacterium prevents wounds from healing by chemically paralyzing skin cells rather than attacking them directly. Scientists from an international research group led by Nanyang Technological University, Singapore (NTU Singapore), have identified an approach that may help chronic wounds heal faster, including wounds infected with antibiotic-resist…

Diabetic wounds, particularly foot ulcers, are among the most serious complications faced by patients with diabetes. These chronic wounds often fail to heal properly due to a combination of poor blood flow, persistent inflammation, and infection. The consequences can be severe, ranging from loss of mobility to amputations, and they place a substantial burden on healthcare systems worldwide. Again…

Microneedles allow scientists to precisely control the delivery of drugs to chronic wound sites and restore natural healing processes. The post Silk microneedles could restore wound healing in diabetic patients appeared first on Advanced Science News .

Speeding up diabetic wound healing Releasing the 'healing brake' on our immune system Chronic skin wounds affect many diabetic patients, with a negative impact on their quality of life. Sophia Maschalidi (VIB-UGent) discovered how to accelerate wound healing and decrease the risk of infection. Key facts (estimates for 2021 from the International Diabetes Federation) - Globally, an estimated 537 m…

It’s not pretty, and its name is a turnoff. But a venous leg ulcer (VLU) should be taken seriously, because of the consequences if it doesn’t heal. Improved treatment of [...] The post Toward Better Wound Healing appeared first on NEOMED .

New insights on circumventing a key obstacle on the road to anti-scarring treatment have been published by Maksim Plikus, an […]

Severe skin injuries affect millions of patients each year worldwide. These lead to serious issues, such as the formation of nonfunctional large scar tissue and the loss of skin appendages (such as hair follicles and sebaceous glands; etc). This can cause the patients insufferable bodily discomfort and a poor quality of life. Current available treatments […]

Doctors have stumbled onto a potential new use for two approved medications. When used in combination, they heal wounds more quickly with less scar tissue. In mice and rats, injecting the two drugs in combination speeds the healing of surgical wounds by about one-quarter and significantly decreases scar tissue. [related] If the findings, published in the Journal of Investigative Dermatology, hold…

Grape-seed extract may help skin wounds heal faster and with less scarring, a new study suggests. The extract seemed to aid wound healing in two ways: It helped the body make more of a compound used to regenerate damaged blood vessels, and it also increased the amount of free radicals in the wound site. Free radicals help clear potentially pathogenic bacteria from a wound. From Ohio State Univers…
