Fast Isomerizing Methyl Iodide Azopyridinium Salts for Molecular Switches
Organic Letters, 2010 The usefulness of azopyridinium methyl iodide salts for designing new promising light-controlled molecular switches is presented. Large absorbance changes have been produced in the samples by irradiation with light at lambda = 355 nm. The thermal recovery of the initial state took place completely within 130-450 ms, which is much faster than that ...

Salt, Salt Sensitivity, and the Endothelium [PDF]
Hypertension, 2013 See related article, pp 951–956 This issue of Hypertension contains a report of molecular mechanisms transducing dietary salt intake1 that may have broad clinical relevance. These molecular mechanisms are complex, but to begin to understand this study we have to understand the importance of dietary salt intake and salt sensitivity.
