Understanding The Underlying Mechanism Of Age-Related Underactive Bladder And Proposing A Treatment Option To Mitigate Its Symptoms, Arezoo Gerami Pour
FIU Electronic Theses and Dissertations
The prevalence of underactive bladder (UAB) increases with age, suggesting a link between age-related processes and lower urinary tract (LUT) symptoms; however, the underlying mechanisms of age-related UAB are poorly understood. UAB is characterized by inefficient voiding and bladder overdistension. Due to the unknown etiology, current therapeutic options are insufficient. Thus, a detailed understanding of its mechanism will facilitate the discovery of new treatments.
In Aim 1, we investigated the relationship between age and systems-level function of the LUT reflexes in three age groups of rats, testing the hypothesis that aging causes voiding reflexes to weaken. We systematically investigated the …

Peristalsis, the coordinated contraction and relaxation of the muscles of the stomach, is important for normal gastric motility and is impaired in motility disorders. Coordinated electrical depolarizations that originate and propagate within a mutually coupled network of interstitial cells of Cajal (ICC) and smooth muscle cells of the stomach wall as a slow-wave, underly peristalsis. Normally, the gastric slow-wave (GSW) oscillates with a single period and uniform rostro-caudal lag, exhibiting network entrainment. Loss of entrainment in the coupled network and the resulting impairment in slow-wave propagation is associated with various gastric motility disorders. Our study provides an enhanced understanding of …
