Enzyme histochemistry and hormones of the developing gastrointestinal tract of the chick embryo. I. A histochemical and quantitative study of glycogen, uridine diphosphate glucose-glycogen transglucosylase, glucose-6-phosphatase and phosphorylase.
TL;DR: In this article, glueagon has been histochemically demonstrated by the fluorescent antibody technique in the developing gastrointestinal tract of the chick embryo and the levels of monoamine oxidase activity at various stages during the development of the gastrointestinal tract has been studied.
Journal ArticleDOI
Effects of calcium supplementation, calcium source and lactose on iron absorption in the rat
TL;DR: In this paper, the authors show that Ca in the form of CaCO 3 and CaCM, has a more pronounced effect on iron bioavailability than Ca in dairy products (except for yogurt) and that Fe−Ca interactions are influenced by the physiological state of the animal.

Structure, biosynthesis and regulation of lactase-phlorizin hydrolase
Ove Norén,Hans Sjöström +1 more
TL;DR: It is suggested that lactase-persistence is caused by a mutation that either destructs a repressive cis-element (or a cis- Element binding a destabilising protein) or creates an enhancing cis- element interacting with activating factors which increase after weaning.

Lactose absorption in the premature infant.
TL;DR: The purpose of this study was to determine if the premature infant, at 2 weeks of age, possessed normal intestinal disaccharidase activity as measured by oral tolerance tests.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

The digestive function of the epithelium of the small intestine. II. Localization of disaccharide hydrolysis in the isolated brush border portion of intestinal epithelial cells.
David T. Miller,Robert K. Crane +1 more
TL;DR: The epithelial brush border membrane has been isolated as a morphologically distinct entity from homogenates of intestinal mucosa and found to contain virtually all of the invertase and maltase activities of the unfractionated homogenate.

A cytochemical study on the pancreas of the guinea pig. I. Isolation and enzymatic activities of cell fractions.
TL;DR: The incorporation of labelled leucine into the proteins of microsomal subtractions and in those of postmicrosomal fractions was studied comparatively in the pancreas of fasted and fed guinea pigs as well as in the liver and pancrea of fasting animals.
