W.J. White,D. Kopp,C.M. Lang +2 more
TL;DR: A study on the distribution of sucrase and maltase activities in the small intestines of weanling hamsters yielded the following findings: between six and nine weeks after birth, a significant increase in jejunal activities and a concomitant decrease in duodenal activities.

Changes in the pattern of intercellular transfer of lucifer yellow between villus epithelial cells during postnatal development.
Hazel Cheng,Matthew Bjerknes +1 more
TL;DR: It is suggested that the development of an osmolality gradient in taller villi, a result of sodium pumps and a countercurrent multiplier, may be responsible for the changes in the pattern of dye transfer observed.

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.
