The idea that your bladder shrinks as you get older may be nothing more than an old wives tale according to a University of Pittsburgh study. The feeling may, however, signal a treatable underlying condition. Results are to be presented today at the annual meeting of the American Urological Association (AUA) in San Antonio, and will be published in abstract 1218 in the AUA proceedings.
"Many of us, after reaching a certain age, notice that we have to urinate more frequently and with more urgency. The standard assumption, that seems to have become part of our folklore, is that your bladder shrinks as you get older. We found that this may not be the case," said Neil Resnick, M.D., professor and chief, division of geriatric medicine, University of Pittsburgh School of Medicine.
In the study, the researchers compared data on a number of variables including bladder capacity and stability, urethral closure pressure, voiding flow rate and detrusor contraction strength from 95 females between the ages of 22 and 90. The researchers found that while bladder and urethral function deteriorate throughout adult life, bladder capacity rarely changes.

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...
