British Journal of Clinical Pharmacology, EarlyView.Acutely lowering salivary pH (with sugar‐containing acidic gum vs. sugar‐free gum) augments salivary nitrate reduction to nitrite, plasma nitrite concentration, and blood pressure lowering with dietary nitrate. Modifying salivary pH reveals a mechanism by which the nitrate‐nitrite‐NO pathway may be upregulated/inhibited, with potential for other ...

Thiocyanate concentration in saliva of cystic fibrosis patients.
Folia Histochemica et Cytobiologica, 2008 Thiocyanates (SCN-) are ubiquitous in nature. There are indispensable part of host defense system that act as a substrate for lactoperoxidase (LPO). In our study we present initial data on SCN- concentration in saliva of CF patients in comparison to ...

Carbon Energy, EarlyView.By modifying wide‐bandgap high‐Cs perovskite surfaces with quaternary ammonium salts of varying alkyl‐chain lengths, tetrapropylammonium bromide (TPABr) is shown to successfully construct a 1D/3D heterojunction. This structure effectively passivates interface defects and optimizes energy level alignment, achieving a champion efficiency of 20.14% with ...
