The findings of a new study published in the Journal of Cardiovascular Electrophysiology demonstrate that the use of high resolution imaging can greatly aid physicians who are treating patients suffering from a particular type of irregular heart beat.
The study, conducted at the Taipei Veterans General Hospital in Taipei, Taiwan, provides insight into the mechanism of atrial flutter, a common heart rhythm disturbance that circulates around the atria, or top chambers of the human heart. Three-dimensional illustrations of the electrical pathways in 26 patients with atrial flutter documented multiple patterns of abnormal contractions through the heart, contractions that could have been missed by more conventional diagnostic methods.
“We were able to show that 3D mapping in our patients uncovered additional abnormal electrical circuits,” says Dr. Ching-Tai Tai, author of the published article. “These were subsequently eliminated using radiofrequency heat energy delivered through a catheter in the heart to destroy a critical part of the atrial tissue that was causing the irregular beats and cure the patients.”

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...
