Performing x-rays using iodine dye increases risk for kidney failure

Performing x-rays using iodine dye places patients with impaired kidney function at increased risk for kidney failure. Known as Contrast-Induced Nephropathy (ne-FROPP-a- thee) or ''CIN,'' this complication is the third most common cause of hospital-acquired kidney failure in the United States and Europe, accounting for 10-12 percent of all such cases.

Decoy receptor 3 expressed in rheumatic synovial fibroblasts protects the cells against Fas-induced apoptosis

A complex autoimmune disease, rheumatoid arthritis (RA) is characterized by chronic inflammation and progressive joint damage. This process begins with hyperplasia, or excessive increase in size and thickness, of synovial tissue. Along with provoking cartilage and bone destruction, this abnormal tissue growth is resistant to apoptosis, the natural cell death vital to the generation of healthy new cells.
