Separation and properties of β-galactosidase, β-glucosidase, β-glucuronidase and n-acetyl-β-glucosaminidase from rat kidney
TL;DR: DEAE-cellulose chromatography and filtration on Sephadex gels suggests that the β-glucosidase component is a small acidic molecule, of molecular weight approx.

Primary adult lactose intolerance and the milking habit: a problem in biological and cultural interrelations. I. Review of the medical research.
TL;DR: The non-milking attitude, a cluster of views that nonmilkers use to explain their abstention from milk, involves elements of biological as well as of cultural origin this paper.

Digestion and absorption
A.. Hinsberger,Bhupinder Sandhu +1 more
TL;DR: Improved understanding of gastrointestinal tract physiology has led to major progress in the treatment of gastrointestinal disorders, and the development of oral rehydration therapy based on understanding of sodium transport across the enterocyte has helped to save thousands of lives each year.

TL;DR: There was very active crypt formation before weaning, which likely continued into adult life but at a lower level, and as the width of villi increased with age, the number of crypts assoiated with a villus also increased (presumably as a result of net crypt production in the adult).

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.
