A cutting-edge blood test discovered by Indiana University School of Medicine researchers could help more accurately diagnose military veterans and other people experiencing post-traumatic stress disorder, and potentially provide more precise treatments and prevention. A study led by psychiatry professor Alexander Niculescu, MD, Ph.D., and published this week in the high-impact SpringerNature journal Molecular Psychiatry,...

Electrically syncing up brain regions improves depression in first-of-its-kind study
In a first-of-its-kind study from researchers at the University of North Carolina (UNC) School of Medicine, a new kind of non-invasive electrical brain stimulation has been trialed in patients with major depression. The results show this new technique to be extraordinarily promising in reducing depressive symptoms, with larger trials set to explore this novel treatment...

Handheld Skin Bioprinter Heals Deep Open Wounds With Patient’s Own Cells
The human organism has a number of physiologic processes that work together to heal skin wounds. Sometimes wounds are so large and difficult that these healing mechanisms simply can’t access damaged tissues. Researchers at Wake Forest Institute for Regenerative Medicine in North Carolina are now reporting the development of a bioprinter that uses a patient’s own skin cells to heal wounds faster and more consistently. The device is...

Insulin protects against colorectal cancer
Excess weight promotes the development of insulin resistance and the incidence of colon cancer. Scientists from the Max Planck Institute for Metabolic Research in Cologne identified a new mechanism of the insulin signaling in the intestinal mucosa, which is responsible for maintaining the intestinal barrier and explains the connection between insulin resistance and intestinal cancer....

Scientists delineate pathway that helps us make antibodies
MEDICAL COLLEGE OF GEORGIA AT AUGUSTA UNIVERSITY AUGUSTA, Ga. (March 13, 2019) – Our bodies are continuously concocting specific antibodies to thwart invaders like a virus or even pollen, and scientists have new information about how the essential production gets fired up and keeps up. It’s a key protective mechanism that the scientists want to...

Starving leukemia cells by targeting amino acids
Altered metabolism in cancer cells EMORY HEALTH SCIENCES Cancer cells consume sugar at a higher rate than healthy cells, but they’re also hungry for amino acids, the building blocks of proteins and other biomolecules. Researchers at Winship Cancer Institute of Emory University have discovered a way to exploit that hunger to selectively block the growth of leukemias. The results were published...

Researchers explore link between metal exposure and Parkinson’s symptoms
A new study from Iowa State University biomedical researchers illuminates the biological processes by which exposure to some metals can contribute to the onset of Parkinson’s-like symptoms. The study, published today in the peer-reviewed journal Science Signaling, focuses on the metal manganese, which has a range of industrial uses as an alloy. Anumantha Kanthasamy, a...
