TL;DR: A classification system for the epithelial changes that occur in ulcerative colitis was developed, which should be applicable to other forms of inflammatory bowel disease as well and makes use of standardized terminology, addresses specific problem areas, and offers practical solutions.

TL;DR: The findings of this work support the original hypothesis, derived previously from mathematical modeling of crypt dynamics, that progressive colonic SC overpopulation occurs during colon tumorigenesis and drives CRC development.

TL;DR: Results of the phantom study confirmed that the dual-flip angle algorithm can be used to correctly identify the dominant constituent, allowing depiction of 0%-100% of fat content.

TL;DR: Clinically unresponsive, surgically resected achalasia has almost total loss of ganglion cells, and widespread destruction of myenteric nerves has already occurred, and it cannot be determined whether this inflammation is a manifestation of ongoing nerve destruction or whether it is a secondary phenomenon.

TL;DR: During an eight-year period, 17 patients ranging in age from 7 months to 81 years were found to have arteriovenous malformations of the gastrointestinal tract complicated by major hemorrhage, and a clinical classification of AVMs was developed, based on angiographic characteristics, localization, age of the patient, and family history.
