Dysfunctions of the lower urinary tract such as overactive bladder syndrome and incontinence are the product of storage failure. Spontaneous regional bladder wall movements (non-micturition contractions, NMCs) are proposed to generate afferent activity that signals volume status to the CNS. The sympathetic nervous system, via activation of β-adrenoceptors (β-AR), causes ...

Angiotensin II receptor antagonists (ARBs) have a protective effect in patients with chronic kidney disease (CKD) by suppressing progression, possibly by controlling hypertension. One marker of progression in such patients is the degree of proteinuria. We aimed to retrospectively examine the protective effect of ARBs (olmesartan, losartan, candesartan, and valsartan) ...

PURPOSE: Intra-abdominal hypertension is frequently underdiagnosed and defined by intra-abdominal pressure (IAP) 12 mm Hg or higher. Increasing IAP may compromise organ viability and culminate in abdominal compartment syndrome. Bladder pressure measurement is a surrogate for IAP, but measurement properties are unknown in the intensive care unit. Our primary objective ...

Diversity is expected to increase the resilience of ecosystems. Nevertheless, highly diverse ecosystems have collapsed, as did Lake Victoria's ecosystem of cichlids or Caribbean coral reefs. We try to gain insight to this paradox, by analyzing a simple model of a diverse community where each competing species inflicts a small ...
