Medical Xpress / Blocking a mitochondrial transporter may curb inflammation from 'zombie' cells without killing them
Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases. The findings reveal how dysfunctional mitochondria—the cell's energy-producing ...
Medical Xpress / Beyond arthritis: Three causes of hip pain that can lead to joint replacement
When an adult sees a doctor and complains about persistent hip pain, the assumption is often wear-and-tear-related osteoarthritis. However, hip pain not caused by arthritis can come from conditions that are both more complex ...
