Just as people’s joints can get stiff as they age and make it harder for them to move around, hair follicle stem cells also get stiff, making it harder for them to grow hair, reports a new Northwestern Medicine study. But if the hair follicle’s stem cells are softened, they are more likely to produce […]
Collaborating researchers from the University of Pennsylvania School of Dental Medicine and the Adams School of Dentistry and Gillings School of Global Public Health at the University of North Carolina have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. Scientists have long considered another bacterial species, […]
Researchers have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. Scientists have long considered another bacterial species, the plaque-forming, acid-making Streptococcus mutans, as the principal cause of tooth decay. However, in the study, S. sputigena, previously associated only with gum disease, can work as a key […]
A team of scientists from the Institute for Research in Biomedicine (IRB Barcelona) in collaboration with the National Center for Genomic Analysis (CNAG) has discovered that IL-17 protein plays a central role in skin ageing. The study, which was led by Dr. Guiomar Solanas, Dr. Salvador Aznar Benitah, both at IRB Barcelona, and Dr. Holger […]
Researchers at the Department of Biology, University of Copenhagen, have now contributed to solving this problem for a specific gene called GCK. Rasmus Hartmann-Petersen, Professor at the Department of Biology, explains:– “The GCK gene, which codes for the enzyme glucokinase, regulates the secretion of insulin in the pancreas. GCK gene variants can therefore cause a […]
Acting as a team, twin stem cells activate the immune system to suppress tumor growth and prolong survival in representative preclinical models. Overall survival for patients with melanoma that has spread to the brain is only four to six months. Immunotherapies, which harness the power of the immune system to attack cancer cells, have garnered […]
A typical human cell is metabolically active, roaring with chemical reactions that convert nutrients into energy and useful products that sustain life. These reactions also create reactive oxygen species, dangerous by-products like hydrogen peroxide which damage the building blocks of DNA in the same way oxygen and water corrode metal and form rust. Just how […]
Noninvasive glucose monitoring devices are not currently commercially available in the United States, so people with diabetes must collect blood samples or use sensors embedded under the skin to measure their blood sugar levels. Now, with a new wearable device created by Penn State researchers, less intrusive glucose monitoring could become the norm. The researchers […]
Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria’s metabolism. Each year, more than five million people worldwide die […]
In an international study co-led by UCLA, scientists have shown that a new targeted therapy drug can extend the amount of time people with a subtype of glioma are on treatment without their cancer worsening. The finding suggests a possible new treatment option for people with the slow-growing but deadly brain tumor. The team found […]
