Physiology and pathophysiology of renal aquaporins.
TLDR
Investigation of the aquaporins is providing detailed molecular insight into the fundamental physiology and pathophysiology of water balance and water balance disorders, suggesting a role for AQP2 in the development of water retention.
Potential antioxidants in beer assessed by ESR spin trapping.
TLDR
Sulfite was found to be the only compound that was able to delay the formation of radicals, whereas phenolic compounds such as phenolic acids, catechin, epicatechin, and proanthocyanidin dimers had no effect on the formationof radicals.
Expression and immunolocalization of aquaporin water channels in rat exocrine pancreas.
TLDR
To evaluate the contribution of AQPs to the membrane water permeability, video microscopy was used to measure the swelling of acinar cells in response to hypotonic stress, and the marked effect of Hg(2+) suggests that other water channels may be expressed in the basolateral membrane.
A role for taurine in mitochondrial function
TLDR
By application of the model presented, taurine depletion caused by hyperglycemia could provide a link between mitochondrial dysfunction and diabetes.
Identification of free radical intermediates in oxidized wine using electron paramagnetic resonance spin trapping.
TLDR
Electron paramagnetic resonance spectroscopy was used to detect and identify several free radical species in wine under oxidative conditions with the aid of spin traps, providing the first direct evidence of the Fenton reaction in wine.
The important role of taurine in oxidative metabolism.
TLDR
A general biochemical model with preliminary data demonstrating the important role of taurine as mitochondrial matrix buffer for stabilising the mitochondrial oxidation is developed, which represents a new concept for understanding mitochondrial dysfunction by emphasising the importance of taurus for providing sufficient pH buffering in the mitochondrial matrix.
