Gastrointestinal endoscopy, 76(6), 1170-1174 (2012-10-03)
Colon capsule endoscopy (CCE) is a noninvasive technique for the detection of colorectal lesions. However, for CCE to be offered as an out-of-clinic procedure, the system needs to automatically alert the patient when to ingest the laxative (booster). We tested

Journal of proteome research, 14(1), 120-132 (2014-10-21)
Interactions between a host and a bacterial pathogen are mediated by cross-talk between molecules present on, or secreted by, pathogens and host binding-molecules. Identifying proteins involved at this interface would provide substantial insights into this interaction. Although numerous studies have

The rate of obesity among men of reproductive age has tripled in the last three decades. Previously, we demonstrated that paternal obesity resulted in impaired preimplantation developmental kinetics, compromised post-compaction metabolism and decreased blastocyst cell number when embryos were generated

Understanding drug glucuronidation in the dog, a preclinical animal, is important but currently poorly characterized at the level of individual enzymes. We have constructed cDNAs for the 10 dog UDP-glucuronosyltransferases of subfamily 1A (dUGT1As), expressed them in insect cells, and
