Chronic wounds like bedsores affect millions in US, causing widespread infections and limb amputations. Researchers found skin cells get stuck in healing process due to overabundance of c-myc, a molecule that suppresses cell migration and causes thickened layers around the wound.
A study published in Science identifies the master gene grainyhead as essential for wound repair in both fruit flies and mice. The researchers found that grainyhead is required to activate genes involved in cuticle repair, which then regenerate injured patches of skin.
A small study found that maggot-treated wounds had a significantly lower infection rate compared to untreated wounds. Maggots' unique properties make them an effective treatment option for preventing post-operative wound infections.
A new study found that social bonding has a positive effect on wound healing in monogamous mice but not in those with multiple partners. Corticosterone levels, a stress hormone, were lower in socialized monogamous mice and showed no difference in non-monogamous mice.
Researchers found that socially isolated hamsters healed wounds at a slower rate than those paired with a sibling, which also reduced stress hormone cortisol levels. Oxytocin treatment improved wound healing in stressed and non-stressed animals.
New prosthetic fitting system offers improved match for knee arthritis patients, while researchers find nearly 80% of patients satisfied with brace treatment. Meanwhile, studies on traumatic brain injury research reveal legal and ethical concerns, as well as effective wound healing methods using electrical stimulation.
A study published in PLOS Biology discovered a common genetic signature linked to the progression of various cancers, including prostate and liver cell carcinomas. Patients with tumors carrying this signature had an increased risk of metastasis and death compared to those without it.
Pregnant women exhibit enhanced odor sensitivity and unpleasantness, which may help protect against stress. A study also found that brain areas mediating 'reward' are stimulated by pup suckling in rat mothers, suggesting a potential link between smell, reward, and maternal bonding.
Researchers at UC San Diego discovered that a protein essential for fruit fly embryonic development also plays a crucial role in mammalian wound healing. The study reveals that the loss of this protein causes skin cells to bunch up and stall, leading to slower wound healing rates.
MIF is a crucial intermediary in uncontrolled inflammation and impaired wound healing. In estrogen-deficient mice, MIF expression increased, leading to excessive inflammation and delayed healing. Therapeutics that inhibit MIF may accelerate wound healing.
The new mat mimics natural clotting processes by creating fibers of similar dimensions to those found in the body. It can be used for minor cuts or severe battlefield wounds, promoting clotting and eventual absorption by the body.
A study by Ohio State University found that topical oxygen therapy significantly improved healing rates for difficult-to-treat wounds, including diabetic hand ulcers and bedsores. The therapy, which involves applying pure oxygen to the wound, showed a 75% healing rate for acute traumatic injuries.
Researchers at McGill University have discovered a molecule that accelerates wound healing, providing a potential treatment option for millions of Americans suffering from burns and chronic skin ulcers. The growth factor progranulin has been shown to improve skin repair, offering new hope for individuals affected by these conditions.
Grape seed extract enhanced wound healing in mice and human skin cells by promoting epidermal tissue formation and connective tissue deposition. It also increased levels of VEGF, a compound that helps rebuild blood vessels.
Researchers at Texas A&M University are investigating the healing properties of Aloe vera, particularly its polysaccharide, which binds growth factors in wounds and speeds up the healing process. The study aims to improve wound healing for elderly patients with bedsores, diabetic ulcers, and vascular ulcers.
Researchers have identified gamma-delta T cells as a crucial component of the immune system in wound repair. These cells recognize an antigen released by keratinocytes during injury and produce growth factors that help proliferate epithelial cells, leading to wound closure.
Researchers at UC Riverside have identified a chicken chemokine, cCAF, that plays a critical role in wound healing and may help accelerate the process in humans. The discovery has potential for treating wounds in diabetics, people with pressure ulcers, and those with bedsores.
Researchers identify PPARbeta as a key gene regulator in the cellular response to inflammation and wound healing. The protein is crucial for keratinocyte differentiation and migration, enabling effective wound healing.
Researchers discover SLPI protein promotes healing in non-healing wounds, reversing tissue destruction and hastening recovery. The study's findings may lead to new treatments for delayed wound healing in the elderly.
A University of Washington study reveals that women who have Caesarean or assisted vaginal deliveries are at a higher risk of rehospitalization compared to those who have unassisted vaginal deliveries. The study found significant risks for complications such as uterine infection, postpartum hemorrhage, and cardio-pulmonary conditions.
A new study led by UCSF scientists found that giving patients more oxygen during and after anesthesia can cut the rate of surgical wound infections in half. The increased oxygen improves immune cells' ability to fight infections, reducing hospitalization time and costs.
Researchers at The Wistar Institute have identified multiple regions on five different chromosomes responsible for wound healing and regeneration in mammals. The study, led by Ellen Heber-Katz, reveals the genetic basis of tissue regeneration in mice, with potential applications in human medicine.
A new study found that stress can lengthen the time dental wounds take to heal by 40% and reduce interleukin-1 production, a crucial cytokine for wound healing. Researchers believe that early supportive therapies may counteract this slowing effect, which occurs in the first few days after injury.
A recent study found that two out of every three female veterinarians have reported accidental needlestick wounds, with side effects reported in 16.4% of cases. Vaccines were the most commonly injected substances, followed by anesthetics and euthanasia drugs.
