Their research could lead to a device that would restore bladder control for the more than 200,000 Americans living with spinal cord injury or disease-related spinal cord problems
Biomedical engineers at Duke University’s Pratt School of Engineering have demonstrated for the first time that stimulating a specific nerve in the pelvis triggers the process that causes urine to begin flowing out from the bladder, refuting conventional thinking that "bladder emptying" requires signals from the brain. Their research, carried out with animals, could lead to a "bladder pacemaker" to restore bladder control for the more than 200,000 Americans living with spinal cord injury (SCI) or disease-related spinal cord problems.
Neural engineer Warren Grill and biomedical engineering doctoral candidate Joseph Boggs found that applying small electrical currents to the pudendal nerve triggered coordinated contraction of the bladder and relaxation of the urethral sphincter, which controls the bladder’s outlet. The electrical stimulation emptied 65 percent of the bladder’s volume.

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...
