Plasma kinetics of zeaxanthin and 3'-dehydro-lutein after multiple oral doses of synthetic zeaxanthin.
BACKGROUND Zeaxanthin is hypothesized to reduce the risk of age-related macular degeneration; however, kinetic information is limited. OBJECTIVES The objective was to investigate the plasmaExpand

Role of lipase in the regulation of postprandial gastric acid secretion and emptying of fat in humans: a study with orlistat, a highly specific lipase inhibitor
BACKGROUND AND AIMS To investigate the importance of lipase on gastric functions, we studied the effects of orlistat, a potent and specific inhibitor of lipase, on postprandial gastric acidity andExpand

Role of lipase in the regulation of upper gastrointestinal function in humans.
The role of lipase in the regulation of upper gastrointestinal function is poorly understood. We studied the effect of orlistat, a new, potent, and highly specific lipase inhibitor, on gastricExpand

Degree of in vivo inhibition of human gastric and pancreatic lipases by Orlistat (Tetrahydrolipstatin, THL) in the stomach and small intestine.
BACKGROUND AND AIMS Orlistat, a lipase inhibitor, strongly inhibits the activities of all gastric/pancreatic lipases except pancreatic phospholipase A(2)in vitro. In clinical use, for obesityExpand
