The number and probability of canalizing functions [PDF]

, 2003
Canalizing functions have important applications in physics and biology. For example, they represent a mechanism capable of stabilizing chaotic behavior in Boolean network models of discrete dynamical systems. When comparing the class of canalizing functions to other classes of functions with respect to their evolutionary plausibility as emergent ...

Late anastomotic complication after laparoscopic surgery for clinical stage I low rectal cancers located within 5 cm of the anal verge: Sub‐analysis of the ultimate trial

Annals of Gastroenterological Surgery, EarlyView.
Anastomotic stenosis and late fistula formation frequently emerge as secondary consequences of early AL, and represent significant complications linked to permanent stoma creation, often proving resistant to treatment. Intestinal prolapse is a characteristic anastomotic complication of ISR that can be caused by excessive intestinal mobilization.

Nutritional benefits of pancreas‐sparing total duodenectomy for severe duodenal polyposis in patients with familial adenomatous polyposis

Annals of Gastroenterological Surgery, EarlyView.
The postoperative nutritional status of patients with familial adenomatous polyposis who underwent pancreas‐sparing total duodenectomy was better than that of patients who underwent pancreaticoduodenectomy. This study provides the first direct comparison of postoperative nutritional outcomes between patients with pancreas‐sparing total duodenectomy and

A Bayesian joint model for mediation analysis with matrix-valued mediators [PDF]

arXiv, 2023
Unscheduled treatment interruptions may lead to reduced quality of care in radiation therapy (RT). Identifying the RT prescription dose effects on the outcome of treatment interruptions, mediated through doses distributed into different organs-at-risk (OARs), can inform future treatment planning.

Reoperative pouch surgery for suspected Crohn's‐related complications aided by biologic coverage: Early experience from an inflammatory bowel disease center

Annals of Gastroenterological Surgery, EarlyView.
This paper demonstrates that revisional/redo ileal pouch anal anastomosis (IPAA) surgery with concurrent biologic therapy provides a viable, stoma‐free alternative for patients with Crohn's disease‐like complications, showing a high functioning pouch rate and expanding options for managing pouch failure.
