Scientists Discover Genes Causing Age-Related Hearing Loss

Researchers are simply beginning to unwind the hereditary reasons for age-related hearing loss. (Credit: Tish1/Shutterstock) Although our ears grow as we age, our hearing tends to fade. This paradoxical issue prevails and gets gradually even worse the older we get. An approximated 25 percent of Americans in between the ages of 65 and 74 have … Read more

SRC-1 gene variants linked to human obesity

Credit: CC0 Public Domain Maintaining a healthy body weight is no simple matter. A better understanding of how the body regulates appetite could help tip the scale toward the healthy side. Contributing toward this goal, a team led by researchers at Baylor College of Medicine and the University of Cambridge reports in the journal Nature … Read more

Ketamine reverses neural changes underlying depression-related behaviors in mice

3-D model of Ketamine. Credit: Wikipedia Researchers have identified ketamine-induced brain-related changes that are responsible for maintaining the remission of behaviors related to depression in mice—findings that may help researchers develop interventions that promote lasting remission of depression in humans. The study, funded by the National Institute of Mental Health (NIMH), part of the National … Read more

A tiny cry for help from inside the liver could lead to better treatment

Depiction of the newly discovered role of the enzyme CPS1 in sounding the alarm about liver damage and bringing in anti-inflammatory immune cells. Credit: University of Michigan On a normal day, the cells of a human liver do what they do best—making key blood proteins, clearing toxins from the blood and sending their remains down … Read more

Could eating garlic reduce aging-related memory problems?

Oral allyl sulfide administration reduces the age-related memory problem through restoration gut bacteria in the intestine (rNDNF= recombinant neuronal-derived natriuretic factor).

Consuming garlic helps counteract age-related changes in gut bacteria associated with memory problems, according to a new study conducted with mice. The benefit comes from … Read more

High Fructose Corn Syrup Can Help One Kind of Tumor Grow

(Credit: NaughtyNut/Shutterstock) Health experts have been wary of high fructose corn syrup for years. The sweetener — common in soda and processed foods — has increasingly crept its way into our meals. At the same time, rates of obesity and diseases like type 2 diabetes and high blood pressure have increased. Now, a new study … Read more

Scientists find new therapy target for drug-induced liver failure

Findings from a new mouse study suggest that treatments that increase levels of the protein thrombospondin-1 could help the liver recover from an overdose of acetaminophen. Credit: Matthew McMillin Acetaminophen—a commonly used pain reliever and fever reducer—is the leading cause of quickly developing, or acute, liver failure in the U.S. Findings from a new mouse … Read more

New PET imaging biomarker could better predict progression of Alzheimer’s disease

Researchers have discovered a way to better predict progression of Alzheimer’s disease. By imaging microglial activation levels with positron emission tomography (PET), researchers were able to better predict progression of the disease than with beta-amyloid PET imaging, according to a study published in the April issue of the Journal of Nuclear Medicine. According to the … Read more

Food additive may influence how well flu vaccines work

Michigan State University scientists have linked a common food preservative to an altered immune response that possibly hinders flu vaccines. The study conducted in mice, presented at the 2019 Experimental Biology meeting in Orlando, Fla., April 7 at 9 a.m., offers up a new potential factor in vaccine effectiveness. Tert-butylhydroquinone, or tBHQ, can be found … Read more
