Eprinomectin (LONGRANGE®, E-LR) is the first extended-release injectable cattle dewormer that claims to provide cattle producers season-long persistent parasite control for 100 to 150 d in a …


The Economic Burden Of Gluten-Free Products And The Potential Of Dietary Inhibitors Of Transglutaminase-2, Kristen Kramer Jan 2016

The Economic Burden Of Gluten-Free Products And The Potential Of Dietary Inhibitors Of Transglutaminase-2, Kristen Kramer

LSU Master's Theses

Celiac disease (CD) is a chronic immune-mediated disease of the small intestine caused by the ingestion of gluten. Gluten presents to the intestine largely intact where it is deamidated by Transglutaminase-2 (TG2), increasing affinity for Human Leukocyte Antigen DQ2 (HLA-DQ2) and forming a complex that elicits an inflammatory response ultimately leading to villous atrophy. The only current treatment is strict adherence to a gluten-free diet, though TG2 inhibition is an attractive therapy due its central role in CD pathogenesis. Cocoa contains procyanidin-B2, theobromine and caffeine and may be capable of inhibiting TG2-induced intestinal inflammation and reduce CD symptoms. Procyanidin-B2 rich …
