Mechanistic Comparison between Gastric Bypass vs. Duodenal Switch with Sleeve Gastrectomy in Rat Models
Kodama, Yosuke; Johannessen, Helene; Furnes, Marianne Waldum; Zhao, Chun-Mei; Johnsen, Gjermund; Mårvik, Ronald; Kulseng, Bård; Chen, Duan (Journal article; Peer reviewed, 2013)Background: Both gastric bypass (GB) and duodenal switch with sleeve gastrectomy (DS) have been widely used as bariatric surgeries, and DS appears to be superior to GB. The aim of this study was to better understand the ... -

PYY-Dependent Restoration of Impaired Insulin and Glucagon Secretion in Type 2 Diabetes following Roux-En-Y Gastric Bypass Surgery
Ramracheya, Reshma D.; McCulloch, Laura J.; Clark, Anne; Wiggins, David; Johannessen, Helene; Olsen, Magnus Kringstad; Cai, Xing; Zhao, Chun-Mei; Chen, Duan; Rorsman, Patrik (Journal article; Peer reviewed, 2016)Roux-en-Y gastric bypass (RYGB) is a weight-reduction procedure resulting in rapid resolution of type 2 diabetes (T2D). The role of pancreatic islet function in this restoration of normoglycemia has not been fully elucidated. ... -
Tissue responses to hexyl 5-aminolevulinate-induced photodynamic treatment in syngeneic orthotopic rat bladder cancer model: possible pathways of action
Arum, Carl-Jørgen; Gederaas, Odrun Arna; Larsen, Eivind La Puebla; Randeberg, Lise Lyngsnes; Hjelde, Astrid; Krokan, Hans Einar; Svaasand, Lars O.; Chen, Duan; Zhao, Chun-Mei (Journal article; Peer reviewed, 2011)Orthotopic bladder cancer model in rats mimics human bladder cancer with respect to urothelial tumorigenesis and progression.
