CITY UNIVERSITY OF HONG KONG A research team led by City University of Hong Kong (CityU) scientists recently developed a new generation of microneedles technology which allows the intradermal delivery of living cells in a minimally invasive manner. Their experiment showed that vaccination using therapeutic cells through this ground-breaking technology elicited robust immune responses against tumours in mice, paving...

Implantable Hydrogel Helps Neurons Recover After Traumatic Brain Injury
APRIL 30TH, 2021 MEDGADGET Traumatic brain injuries (TBI) often lead to cognitive disabilities and permanent neural tissue damage, for which effective therapies do not exist. The serious cognitive impairments that patients experience and the burden on caretakers can be enormous, necessitating a constant search for treatments that may help. Researchers at University of Georgia have now...

Low doses of radiation may improve quality of life for those with severe Alzheimer’s
BAYCREST CENTRE FOR GERIATRIC CARE Individuals living with severe Alzheimer’s disease showed remarkable improvements in behaviour and cognition within days of receiving an innovative new treatment that delivered low doses of radiation, a recent Baycrest-Sunnybrook pilot study found. “The primary goal of a therapy for Alzheimer’s disease should be to improve the patient’s quality of...

Engineering T cells to attack cancer broadly
by Virginia Commonwealth University Control mice (left panel) with prostate cancer show large areas of metastasis in the lungs (blue). When a subset of animals were treated with unmodified T cells (middle panel), the secondary tumors were smaller than in untreated mice. And when a separate group of mice received T cells engineered to produce MDA-7/IL-24...

System to deliver electrically activated glue for sealing defects in broken blood vessels
by Nanyang Technological University The Voltaglue patch can be applied to a deflated catheter. Once inserted into a blood vessel, the catheter can be inflated at the site of a break where the patch is activated to harden it and glue the hole shut.

Skin and immune cells coordinate defenses against assault
by Yale University Credit: CC0 Public Domain As the human body’s largest organ, the skin is responsible for protecting against a wide range of possible infections on all fleshy surfaces, from head to toe. So how exactly does the skin organize its defenses against such an array of threats? A new Yale study shows that the...

Sugar-sweetened drinks linked to increased risk of colorectal cancer in women under 50
by Washington University School of Medicine Credit: CC0 Public Domain Colorectal cancer diagnoses have increased among people under age 50 in recent years and researchers are seeking reasons why. A new study led by Washington University School of Medicine in St. Louis has found a link between drinking sugar-sweetened beverages and an increased risk of developing...
