Novel microneedle patch accelerates healing of chronic diabetic wounds using light

Researchers from Nanjing Drum Tower Hospital, Southeast University, and Wenzhou Medical University have developed a novel microneedle patch that combines MXene hydrogel with nitric oxide (NO) and hypoxia-inducible factor-1α (HIF-1α) plasmid for enhanced diabetic wound treatment.

Preventing postoperative rebleeding in intracerebral hemorrhage surgery

Intracerebral hemorrhage (ICH) is the stroke subtype with the highest mortality and disability rates, and early hematoma evacuation is crucial for improving prognosis.

Understanding PIEZO2 mutations and sensory disorders

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal that the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts as a key sensor for touch, it remained unclear why PIEZO2 is specialized for the localized mechanical forces experienced by sensory neurons, whereas its close relative PIEZO1 responds to broader mechanical stresses such as those generated when cells stretch, as occurs in blood vessels.

Surgical robot can help safely remove the caudate lobe

Resection of tumors in the caudate lobe (a deep, hard-to-reach part of the liver) is recognized as one of the most technically challenging procedures in hepatic surgery due to its unique anatomical position and complex vascular relationships.

BCAT2 enzyme identified as a target for diabetic foot recovery

Diabetic macrovascular complications are the main cause of death and disability in diabetes patients, of which vascular calcification is one of the key pathological mechanisms. Calcification in atherosclerotic plaque can cause stiffness and decreased compliance of the vascular wall, and induce atherosclerotic plaque rupture, which increases the risk of acute cardiovascular events.

New microscope captures 3D blood flow and oxygenation at single-cell resolution

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires.

Low-intensity preconditioning boosts neurological outcomes

The team led by Prof. Lin Zhu from Guangzhou Sport University have demonstrated that 4-week low-intensity treadmill exercise before the onset of an ischemic stroke can significantly reduce brain injury and improve neurological outcomes.

Armored CAR T cells overcome tumor defenses in solid cancers

UCLA scientists have developed a next-generation CAR-T cell therapy that can overcome the immunosuppressive tumor microenvironment, a protective shield that tumors use to weaken immune cells, block their attack and fuel tumor growth.

Satellite livers could provide booster function for patients awaiting transplants

More than 10,000 Americans who suffer from chronic liver disease are on a waitlist for a liver transplant, but there are not enough donated organs for all of those patients.

Mathematical model identifies how estrogen protects women from high blood pressure

High blood pressure, or hypertension, affects more than one billion people worldwide and is a leading cause of heart disease and stroke.

Weight-loss drugs may reduce heart damage after heart attack

Weight-loss (GLP-1 mimicking) drugs may help prevent further tissue damage following a heart attack, significantly reducing the risk of further life-threatening complications that affect up to half of all patients, according to a new study led by the University of Bristol and University College London.

Non-invasive immune monitoring via bandage-like microneedle patches

Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body's immune responses painlessly from the skin.

New pathway found connecting liver congestion to fibrosis and cancer

Researchers from The University of Osaka find that chronic liver congestion is linked to severe liver diseases through a specific signaling pathway in liver sinusoidal endothelial cells - key cells lining the liver's tiny blood vessels.

Lymphovenous anastomosis may be an effective treatment for Alzheimer's disease

A small but growing body of evidence suggests that a minimally invasive surgical procedure called lymphovenous anastomosis (LVA) might be an effective treatment for Alzheimer's disease (AD), according to a special article in the March issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Reducing miRNA levels helps rescue vascular defects in Rett syndrome

MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them leaky.

Disrupted lymphatic vessels may drive chronic organ transplant rejection

Despite advances in the field of organ transplantation, long-term organ rejection that can become apparent a decade or more after a heart or lung transplant remains a common problem for patients.

Road traffic noise linked to immediate heart and blood vessel stress

A new study published in the journal Cardiovascular Research shows that a single night of road traffic noise, at levels that are typical of those living in a city, causes stress to the heart and blood vessels.

Rethinking cardiovascular risk assessment in women

Less artery-clogging plaque in women's arteries did not appear to protect them from heart disease compared to men, according to a study published in Circulation: Cardiovascular Imaging, an American Heart Association journal.

New 3D liver reconstructions show how cirrhosis reshapes organ architecture

Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians capture the spatial microstructure of multiple lobes of this multitasking organ.

Study connects vascular health to early Alzheimer’s brain changes

Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC.
