Studies recently carried out at the University Hospital of the University of Navarra show that cardiac resynchronisation therapy using pacemakers and defibrillators improves the survival and quality of life of patients suffering from heart insufficiency and disorders of the blood-flow system.
One of the advances for heart insufficiency developed over the past few years has been the incorporation of biventricular pacemakers and defibrillators. Known as cardiac resynchronisation therapy, their implantation provides the advantage of increasing the performance of the heart in a number of patients with this pathology. In some cases, the heart insufficiency not only involves a loss of contractile force, but also an alteration in the synchronisation of the heart. That is to say, contraction occurs with little force and, moreover, in a disordered manner and, thus, the heart’s performance or yield is notably worsened.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
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...
