Discovery of putative salivary biomarkers for Sjögren's syndrome using high resolution mass spectrometry and bioinformatics.

The purpose of the current study was to determine if saliva contains biomarkers that can be used as diagnostic tools for Sjögren's syndrome (SjS). Twenty seven SjS patients and 27 age-matched healthy controls were recruited for these studies. Unstimulated glandular saliva was collected from the Wharton's duct using a suction device.

Identification of wheat endosperm proteins by MALDI mass spectrometry and LC-MS/MS.

The commercial value of the wheat crop is a function of the quality and amount of the storage protein and starch present in the grain, which in turn are influenced by environmental conditions during grain-fill. To understand how environment modifies the size and composition of wheat grains, we set out to identify the key metabolic and regulatory proteins in developing grain. We present results of initial studies aimed at establishing instrument conditions that will allow us to identify cytoplasmic proteins present in wheat endosperm.

Rapid, non-destructive selection of peanuts for high aflatoxin content by soaking and tandem mass spectrometry.

Peanut lots are subject to aflatoxin levels high enough to cause concern to health agencies and trade channels. A possible solution would be to mechanically sort out high aflatoxin nuts from the process stream. Only highly contaminated nuts would need to be removed.
