Title

Epithelial-Specific Loss of SMAD4 Alleviates the Fibrotic Response in an Acute Colitis Mouse Model

Location

McLean 510

"Mucosal healing is strongly linked to improved clinical outcomes in patients with inflammatory bowel disease; however, the specific role of the epithelium in driving this process in vivo remains poorly defined. To address this, we examined mucosal repair in an acute dextran sulfate sodium–induced colitis model in which epithelial-specific deletion of Smad4 results in an attenuated colitis response. We find that enhanced epithelial wound healing alleviates the fibrotic response." Read more

Title

Compression Technique for Word Problem in HNN Extensions

Location

North Building, Room 316

"This research investigates computational complexity aspects of word problems in HNN extensions. The study builds upon Miller’s classical result demonstrating the existence of HNN extensions with decidable word problems but undecidable conjugacy problems." Read more
