A new study suggests that a diet free from red meat significantly reduces the risk of a type of colon cancer in women living in the United Kingdom. University of Leeds researchers were part of an international team that assessed whether red meat, poultry, fish or vegetarian diets are associated with risk of colon and rectal cancer. When comparing the […]

The longevity and health improvements seen in animals on sulfur amino acid-restricted diets could translate to people, according to Penn State College of Medicine researchers who recently conducted a review of published studies. More research is needed to confirm the benefits in people, the scientists said. Amino acids are the building blocks of all proteins in the body. A subcategory […]

(HealthDay)—Cancer survivors are more likely to have difficulty accessing and affording health care, but the proportion reporting these issues is decreasing, according to a study published online March 29 in JAMA Oncology. Ryan D. Nipp, M.D., M.P.H., from Massachusetts General Hospital and Harvard Medical School in Boston, and colleagues used data from the National Health Interview Survey to examine health […]

When you can’t get to sleep at night, you might explain it to someone as your brain not being able to shut off. While your brain never truly shuts off, when you do fall asleep, your brain sends inhibitory neurons that help reduce conscious awareness to get to a point of deep sleep. Normal sleepers often feel like they’ve fallen […]

The disease mechanism for adult-onset progressive degenerative diseases begins much earlier than previously thought, according to a Northwestern Medicine study published in the Journal of Clinical Investigation. Using a mouse model of spinocerebellar ataxia type 1 (SCA1) genetically engineered to precisely mirror the human disease, a team of investigators showed that there is an altered neural circuitry in the cerebellum […]

A team of Rutgers University and international scientists has determined the molecular target and mechanism of the antibacterial drug fidaxomicin (trade name Dificid). Fidaxomicin was approved in 2011 for treatment of the CDC “urgent threat” bacterial pathogen Clostridium difficile (C. diff) and currently is one of two front-line drugs for treatment of C. diff. Fidaxomicin also exhibits potent antibacterial activity […]

If you keep a close eye on an MRI scan of the brain, you’ll see a wave pass through the entire brain like a heartbeat once every few seconds. This ultra-slow rhythm was recognized decades ago, but no one quite knew what to make of it. MRI data are inherently noisy, so most researchers simply ignored the ultra-slow waves. But […]

Purdue University scientists have found another pathway that Listeria uses to enter the bloodstream, suggesting that forms of the foodborne bacteria considered benign may be more dangerous than once thought. About 600 million people around the world contract listeriosis each year, with 420,000 dying, according to the World Health Organization. In the U.S., 1,600 people are infected each year, causing […]

(HealthDay)—For patients with major depressive disorder (MDD), relapse is associated with brain cortical changes over two years, according to a study published online March 28 in JAMA Psychiatry. Dario Zaremba, from the University of Münster in Germany, and colleagues conducted a longitudinal case-control study involving patients with acute MDD at baseline and healthy controls. Participants were subdivided into groups with […]

A team of researchers with the Dana-Farber Cancer Institute and Brigham and Women’s Hospital in the U.S. has found that introducing an antibody into a cancerous mouse model prevented the escape of ligands from a tumor surface allowing natural killer cells to attack. In their paper published in the journal Science, the group describes their technique and how well it […]
