Medical Xpress / i-DNA 'peek-a-boo structures' form in living cells and regulate genes linked to cancer
DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown that one such structure, ...
Medical Xpress / Surgical innovation may cut ovarian cancer risk by nearly 80%
A prevention strategy developed by Canadian researchers can reduce the risk of the most common and deadly form of ovarian cancer by nearly 80%, according to a new study published today in JAMA Network Open by researchers ...
Medical Xpress / Researchers find brain mechanism behind 'flashes of intuition'
Despite decades of research, the mechanisms behind fast flashes of insight that change how a person perceives their world, termed "one-shot learning," have remained unknown. A mysterious type of one-shot learning is perceptual ...
Medical Xpress / PRISM reanalyzes 4,400 tumors, reshaping the debate over tumor microbiomes
When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi—microorganisms that—if actually present in tumor tissues—could influence how they grow, evade immunity ...
Medical Xpress / Simple patch can make medications safer and more effective
Vancomycin is the antibiotic doctors reach for when almost nothing else will work. It's used in hospitals for serious drug-resistant infections, or for when an infection is spreading through the patient's bloodstream, but ...
Medical Xpress / Study suggests protein made in the liver is a key factor in men's bone health
New research suggests the liver plays a previously unrecognized role in bone health, but only in males. A McGill University-led study published in Matrix Biology found that a protein made in the liver helps regulate bone ...
Medical Xpress / Wildfire smoke exposure tied to 24,000 deaths annually, study finds
Wildfires are growing larger, lasting longer and happening more often as the climate warms—but the toll from their toxic smoke, especially from long-term exposure, remains poorly understood.
Medical Xpress / What HSV-1 does inside the nucleus, and why it may aid early diagnosis
Researchers at the University of Jyväskylä (Finland), in cooperation with national and international research groups, have shown that DNA viruses infect cells and take over the host cell nucleus, inducing dramatic structural ...
Medical Xpress / Stimulating the central thalamus during anesthesia sheds light on neural basis of consciousness
The brains of mammals continuously combine signals originating from different regions to produce various sensations, emotions, thoughts and behaviors. This process, known as information integration, is what allows brain regions ...
Medical Xpress / Experimental bioadhesive patch sticks to wet brain tissue and wipes out most glioblastoma cells
Glioblastoma is the most prevalent and aggressive brain tumor. It proliferates very rapidly, is highly invasive, and there is currently no treatment capable of halting its progression or curing it, which means life expectancy ...
Medical Xpress / Scientists now know why ovarian cancer spreads so rapidly in the abdomen
Ovarian cancer kills more women than any other gynecological cancer. Most patients receive their diagnosis only after the disease spreads throughout the abdomen. Until now, scientists have never fully understood why this ...
Medical Xpress / The body processes good fats and bad fats differently, study finds
The concept of "good fats" and "bad fats" has influenced diet trends, public health policy, and biomedical research for decades. Now, a new study led by Thomas A. Vallim, Ph.D., a researcher and professor of medicine in the ...
