A deep slumber might help buffer against memory loss for older adults facing a heightened burden of Alzheimer’s disease, new research from the University of California, Berkeley, suggests. Deep sleep, also known as non-REM slow-wave sleep, can act as a “cognitive reserve factor” that may increase resilience against a protein in the brain called beta-amyloid […]
A major impediment to treating the deadly brain cancer glioblastoma has been that the most potent chemotherapy can’t permeate the blood-brain barrier to reach the aggressive brain tumor. But now Northwestern Medicine scientists report results of the first in-human clinical trial in which they used a novel, skull-implantable ultrasound device to open the blood-brain barrier […]
Gene-editing therapy aimed at two targets — HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that helps the virus get into cells — can effectively eliminate HIV infection, new research from the Lewis Katz School of Medicine at Temple University and the University of Nebraska Medical Center (UNMC) shows. The study, published online […]
Cartilage is a tissue that protects bones by providing shock absorption and facilitates smooth joint movement. Unfortunately, due to its limited intrinsic healing capacity, stem cell transplantation is a promising therapeutic approach to address cartilage inflammation and damage, as well as to promote cartilage regeneration. However, a major limitation of this technique is the rapid […]
Medication delivered by a novel gel cured 100% of mice with an aggressive brain cancer. “We think this hydrogel will be the future and will supplement current treatments for brain cancer.” said Honggang Cui, a Johns Hopkins University chemical and biomolecular engineer who led the research. Cui’s team combined an anticancer drug and an antibody […]
Antibodies that exist in the joints before the onset of rheumatoid arthritis can cause pain even in the absence of arthritis, report researchers from Karolinska Institutet in Sweden report. “Pain can appear before any sign of inflammation in the joints and can remain a problem after it has healed. Our aim was to find possible […]
Women are about twice as likely as men to be diagnosed with Alzheimer’s disease. Some of that is age; in the U.S., women outlive men by five to six years, and advanced age is the strongest risk factor for Alzheimer’s. But there’s more to it than that, so Alzheimer’s researchers continue to look for other […]
Three years ago, an international study commissioned by the journal Lancet listed 12 modifiable factors that increased the risk of dementia, including three new ones: excessive alcohol, head injury and air pollution. Writing in the May 2, 2023 issue of the Journal of Alzheimer’s Disease, a team of researchers, led by scientists at University of […]
A new study published today reveals an association between poor air quality in India and impaired cognition in infants under two. Lead researcher Prof John Spencer, from UEA’s School of Psychology, said: “Prior work has shown that poor air quality is linked to cognitive deficits in children, as well as to emotional and behavioral problems, […]
How do you build complex structures for housing cells using a material as soft as jelly? Rice University scientists have the answer, and it represents a potential leap forward for regenerative medicine and medical research in general. Researchers in the lab of Rice’s Jeffrey Hartgerink have figured out how to 3D-print the well-defined structures using […]
