Surgeons at University Hospitals of Cleveland have demonstrated that the risk of brain damage associated with the use of the heart lung machine can be significantly reduced by modifying the traditional placement of cannulas (tubing) for returning blood flow to the patient. The findings were presented last month at the American Heart Associations annual Scientific Sessions conference in Chicago, Ill.
The neurological problems associated with bypass surgery have been widely reported. As much as 6 percent to 10 percent of bypass patients will experience memory loss, visual changes, or even stroke. Surgeons believe these outcomes are partly due to "debris" lining the aorta that may break off during surgery--under pressure exerted by the heart-lung bypass machine (which keeps blood flowing to the brain).
Alan Markowitz, MD, and a team of researchers at The Research Institute of University Hospitals of Cleveland and Case Western Reserve University studied the patterns of blood flow to the brain on the heart-lung machine and the risk of stroke from debris released into the aorta, the conventional site of blood return flow to the patient.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
