Researchers uncover a key protein and a promising strategy to prevent bone damage from steroids

The rheumatology and orthopedic researchers discovered that a protein called Basigin, which gets activated in stem cells when people take steroids, is a key reason why bones weaken and blood vessels in bone tissue become abnormal. By blocking Basigin, they were able to protect and even restore bone health in mice, suggesting a promising new treatment path.

Their findings were published in Nature Communications.

“This research is a major step forward in understanding how steroid treatments affect bone health,” said Thomas H. Ambrosi, assistant professor in the Department of Orthopedic Surgery and co-corresponding author of the study...

Three-quarters of all people may host newly identified genetic material called Inocles, which could impact research on oral health, immunity, and even cancer risk. Researchers including those at the University of Tokyo have made a surprising discovery hiding in people’s mouths: Inocles, giant DNA elements that had previously escaped detection. These appear to play a central role in helping bacteria adapt to the constantly changing environment of the mouth...

Everybody develops presbyopia as they age—a difficulty in focusing on near objects and text—and often must resort to reading glasses. However, the solution might be as simple as using special eye drops two or three times a day.

A retrospective study of 766 patients presented at the 43rd Congress of the European Society of Cataract and Refractive Surgeons (ESCRS) has found that the majority could read an extra two, three or more lines on the eye chart used for testing near visual acuity (the Jaeger chart) after using specially formulated eye drops. This improvement was sustained for up to two years.

An unusual therapy developed at The Jackson Laboratory (JAX) could change the way the world fights influenza, one of the deadliest infectious diseases. In a new study in Science Advances, researchers report that a cocktail of antibodies protected mice—including those with weakened immune systems—from nearly every strain of influenza tested, including avian and swine variants that pose pandemic threats.

Unlike current FDA-approved flu treatments, which target viral enzymes and can quickly become useless as the virus mutates, this therapy did not allow viral escape, even after a month of repeated exposure in animals...
