Antibacterial nanozymes: Healing chronic wounds with nanochemistry
Chronic infected wounds are often highly problematic for diabetic patients. However, a team of Chinese researchers has now developed a targeted approach to wound healing that makes use of nanomedicine, and their research has been published in the jou.....»»
Electric Wound Dressing Could Help Injuries Heal Faster
An electric wound dressing can help heal injuries faster than existing methods, according to tests in rats. From a report: Previous research has found that applying electric fields across a cut can speed up wound healing, but this usually requires la.....»»
Tiny electric generators could accelerate wound healing
Tiny dressings that generate electricity in response to movement could accelerate wound healing and tissue regeneration. Scientists in Taiwan reviewed the latest advances and potential applications of wound healing technology in the journal Science a.....»»
A "chemical cocktail" of sewage, slurry and plastic is polluting English rivers
Poor water quality in English rivers is the result of chronic underinvestment and multiple failures in monitoring, governance and enforcement, a report from the UK Parliament's Environmental Audit Committee has claimed......»»
Jerome Powell Says the Fed is Prepared To Raise Rates To Tame Inflation
Jerome H. Powell, the Federal Reserve chair, told lawmakers on Tuesday that a rapidly healing economy no longer needed as much help from the central bank and that keeping inflation in check -- including by raising interest rates -- would be critical.....»»
New insights into asthma drug development
Asthma is one of the most common chronic respiratory diseases worldwide and its prevalence is on the rise. Epidemiological studies reveal that the incidence of asthma ranges from 1% to 18% in various countries. More than 400 million people are suffer.....»»
Step forward in quest to develop living construction materials
Some engineered living materials can combine the strength of run-of-the-mill building materials with the responsiveness of living systems. Think self-healing concrete, paint that changes color when a specific chemical is detected or material that cou.....»»
Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds
A new study suggests that persistent exposure to air pollutants in residential communities can impact health outcomes for COVID-19 patients......»»
MRI’s may be initial window into CTE diagnosis in living; approach may shave years off diagnosis
While chronic traumatic encephalopathy (CTE) cannot yet be diagnosed during life, a new study provides the best evidence to date that a commonly used brain imaging technique, magnetic resonance imaging (MRI), may expedite the ability to diagnose CTE.....»»
AI-powered computer model predicts disease progression during aging
Using artificial intelligence, a team of researchers has developed a novel system that models the progression of chronic diseases as patients age......»»
Defense or repair: How immune cells are controlled during wound healing
Scientists show a causal link between tissue repair, mitochondrial metabolism, and the activation and function of macrophages (scavenger cells)......»»
Long-term exposure to environmentally relevant concentrations of pesticides has deleterious effects on shellfish
According to a study recently published in the journal Science of the Total Environment, exposure to chronic, environmentally relevant concentrations of pesticides registered for use in forest management had adverse effects on the soft-shell clam Mya.....»»
Printing technique creates effective skin equivalent, heals wounds
Researchers have developed an approach to print skin equivalents, which may play a future role in facilitating the healing of chronic wounds. They used suspended layer additive manufacturing, creating a gel-like material to support the skin equivalen.....»»
Effectiveness of ointment that kills antibiotic-resistant bacteria shown
New research 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.....»»
3D printing of blood plasma may speed up wound healing
New research suggests that effective wound healing may be aided by replicating a crucial component of our blood......»»
Potential new therapeutic pathway to clear chronic viral infections
A recent study in mice has uncovered that during chronic viral infection, a protein called BMI-1 gets turned on too early in B cells and messes up the delicate balance of gene expression, resulting in antibodies that are unsuccessful in their endeavo.....»»
Stem cell memories may drive wound repair, and also chronic disease
A trifling paper cut is a site of frenzied activity. Within it, a squad of epidermal stem cells briskly regenerate to patch up the wound. A closer inspection of this war-torn swath of epidermis will reveal that while some of the stem cells are native.....»»
Stamping Bar Codes on Cells To Solve Medical Mysteries
No one really knew why some patients with a white blood cell cancer called chronic lymphocytic leukemia, or C.L.L., relapsed after treatment and got a second cancer. Were some cancer cells just resistant? An unexpected answer to this mystery has been.....»»
3D Printer Using Living Ink Made of Microbes Could Print Healing Structures in Space
"The thought of combining a printer (the bane of office workers) with the bacterium E. coli (the scourge of romaine lettuce) may seem an odd, if not unpleasant, collaboration," writes the New York Times. "But scientists have recently melded the vir.....»»
Endangered deer"s prion gene could protect it from chronic wasting disease
China's Père David's deer was nearly gone in the late 1800s. Just 18 deer—the very last of their kind—were brought into captivity after the rest had been hunted to extinction. When 11 of the deer reproduced, the species had a chance. Today, afte.....»»
Ultrashort-pulse lasers kill bacterial superbugs, spores
Researchers at Washington University School of Medicine in St. Louis have found that multidrug-resistant bacteria and bacterial spores can be killed by ultrashort-pulse lasers. The findings could lead to new ways to sterilize wounds and blood product.....»»
