Abstract:
:The levator ani muscles in women are overloaded by constant supporting abdominal contents, and counteracting rises of abdominal pressure at the level of the urethra. The excessive load leads to a decrease in their type II fibers. This results in stress urinary incontinence due to loss of the fibers responsible for additional compression of the urethra at strain.

杂志文章abstract::We recently demonstrated that amyloid beta peptide (Abeta) is catabolized primarily by a neutral endopeptidase, neprilysin, in the brain and that a neuropeptide, somatostatin (SST), regulates brain Abeta level via modulation of neprilysin activity. Because SST expression in the brain declines upon aging in various mam...
