Caffeine Enhances Modulation of Parasympathetic Nerve Activity in Humans: Quantification Using Power Spectral Analysis - However, contrary to our expectations, this greater increase was due only to the HC (not LC), which reflects the increase in vagal activity.
Targeted Profiling of Common Metabolites in Saliva - Saliva is easy to collect via noninvasive techniques used by individuals with minimal training, and can provide useful metabolic information. At the sample preparation stage, ultrafiltration using microcentrifuge filtration tubes provides an effective method of removing both proteins and particulate matter from saliva samples. If you have filtered your saliva samples, then you can acquire NMR spectra with a NOESY presaturation pulse sequence. On the other hand, if you choose not to filter your samples, several relaxation-edited pulse sequences exist that can remove the broad protein resonances from your spectrum during acquisition, allowing for simpler identification of the small molecule metabolites in the sample.
