Duodenal motility in fasting dogs: humoral and neural pathways mediating the colonic brake

J Wen, ELD Leon, LJ Kost, MG Sarr… - American Journal of …, 1998 - journals.physiology.org

nutrients are infused into the ileum and colon. In the present study, we examined the role of …

Peripheral peptide YY inhibits propulsive colonic motor function through Y2 receptor in conscious mice

L Wang, G Gourcerol, PQ Yuan… - American Journal …, 2010 - journals.physiology.org

Slowing intestinal transit by PYY depends on serotonergic and opioid pathways

HC Lin, C Neevel, JH Chen - American Journal of …, 2004 - journals.physiology.org
Slowing of intestinal transit by fat is abolished by immunoneutralization of peptide YY (PYY),

Ileal brake: neuropeptidergic control of intestinal transit

GW Van Citters, HC Lin - Current gastroenterology reports, 2006 - Springer
Digestion and absorption of a meal are time-intensive processes. To optimize digestion and
absorption, transit of the meal through the gastrointestinal tract is regulated by a complex …

Peptide YY stimulates circular muscle contractions of the isolated perfused canine ileum by inhibiting nitric oxide release and enhancing acetylcholine release

JAET Fox-Threlkeld, EE Daniel, F Christinck… - Peptides, 1993 - Elsevier
Peptide YY (PYY) and neuropeptide Y (NPY), infused into the quiescent isolated perfused

Fat-induced ileal brake in the dog depends on peptide YY

HC Lin, XT Zhao, L Wang, H Wong - Gastroenterology, 1996 - Elsevier
BACKGROUND & AIMS: Fat in the distal gut inhibits transit through the proximal small

Peptide YY augments postprandial small intestinal absorption in the conscious dog

AJ Bilchik, OJ Hines, MJ Zinner, TE Adrian… - The American journal of …, 1994 - Elsevier
