Researchers from University of Tsukuba, in collaboration with scientists in Germany, have created a mouse model of restrictive cardiomyopathy, a disease in which the heart muscle becomes stiff and the heart is unable to properly fill with blood. Their data suggest that the disease results from the accumulation of mutant BAG3 protein, which interferes with the protein quality control system and the machinery for breaking down and recycling damaged proteins, disrupting the heart muscle components.

What The Study Did: This autopsy study examines differences in skeletal muscle and myocardial inflammation in patients who died with COVID-19 versus other diseases.

New research reveals that only a minority of U.S. Medicare beneficiaries with knee osteoarthritis in 2005-2010 used non-surgical care such as physical therapy and knee injections, and few were treated by rheumatologists, physiatrists, or pain specialists. The study, which is published in Arthritis & Rheumatology, also found that non-surgical care was more common in regions with low rates of knee replacement surgery.

A study published in Arthritis Care & Research has uncovered an elevated risk of Parkinson's disease in individuals with osteoarthritis.

By applying mass spectrometry, scientists at the University of Copenhagen provide some of the most detailed data on how mitochondrial proteins cluster into supercomplexes - a process that makes mitochondria more efficient at producing energy. The findings, which were published in Cell Reports, is a precious resource for the scientific community, especially those tackling mitochondrial adaptations to exercise training or mitochondrial diseases.
