Research into the pathology of calcification is building momentum. This program follows the work of scientists and physicians dedicated to the study of calcium in the human body—including how and why it accumulates to fatal levels and how diseases linked to calcification can be prevented, treated, or cured. Science journalist Douglas Mulhall introduces the basic issues; Dr. Clarke Anderson of the University of Kansas Medical Center describes his groundbreaking 1967 discovery concerning matrix vesicles and calcification; and Dr. Catherine Shanahan of King’s College London explains recent findings that micro-particles are released by living as well as dead cells. Case studies are included. Not available in French-speaking Canada. (44 minutes)
