Syage J, Kelly C, Dickason M, Ramirez A, Leon F, Dominguez R, et al.
Am J Clin Nutr . 2018 Mar; 107(2):201-207. PMID: 29529159
Background: Celiac disease (CD) patients adhering to a gluten-free diet (GFD) are exposed frequently to low levels of gluten that contribute to symptoms and persistent intestinal histologic damage. Objective: We...

Syage J, Murray J, Green P, Khosla C
Dig Dis Sci . 2017 Jul; 62(9):2428-2432. PMID: 28755266
Background And Aims: Celiac disease (CD) is a widespread condition triggered by dietary gluten and treated with a lifelong gluten-free diet (GFD); however, inadvertent exposure to gluten can result in...

Kauppila T, Syage J, Benter T
Mass Spectrom Rev . 2015 May; 36(3):423-449. PMID: 25988849
Recent developments in atmospheric pressure photoionization (APPI), which is one of the three most important ionization techniques in liquid chromatography-mass spectrometry, are reviewed. The emphasis is on the practical aspects...
