Metabolic zonation of the liver: The oxygen gradient revisited [PDF]
Redox Biology, 2017 The liver has a multitude of functions which are necessary to maintain whole body homeostasis. This requires that various metabolic pathways can run in parallel in the most efficient manner and that futile cycles are kept to a minimum.

Hepatology, 2018
The liver is composed of approximately a million hepatic lobules, microscopic hexagonal units that are patterned together in a three dimensional vasculature. Blood filters from portal triad points into central vein points at the center of each hexagonal lobule (Fig. 1). The lobule consists of hepatocyte plates that carry a gradient of recently absorbed

Adrenocortical zonation and ACTH
Microscopy Research and Technique, 2003AbstractThe clear morphological distinction between the cells of the different adrenocortical zones has attracted speculation and experiment to interpret their functions and the ways in which they are regulated. Considerable data have been produced in recent years that has benefited a fuller understanding of the processes of steroidogenesis and of cell

Geometries of Mineral Zonation, the Characteristic Geometries of Mineral Zonation
Journal of the Virtual Explorer, 2004A series of numerical experiments using the Elle simulation platform were designed to reproduce zonation patterns resulting from a variety of grain scale processes. Comparison of the patterns of zonation produced allows us to distinguish between mineral zonation arising from diffusion, grain boundary migration driven by surface energy reduction, grain ...

Zonation is one of the most obvious features of a rocky shore and, with a little effort, it can also be recognized on sandy beaches and mudflats. Each species has an upper and lower distributional limit along the vertical intertidal gradient, and the factors which set those limits have long attracted the attention of shore ecologists, particularly for ...

Dynamic zonation of liver polyploidy
Cell and Tissue Research, 2016The liver is a polyploid organ, consisting of hepatocytes with one or two nuclei each containing 2, 4, 8 or more haploid chromosome sets. The dynamic changes in the spatial distributions of polyploid classes across the liver lobule, its repeating anatomical unit, have not been characterized.

There is ample evidence that a progressive change in the intensity of an important environmental factor leads to the formation of zones or belt-like communities in which the plant species reflect a fairly distinct range of tolerance for that factor (Daubenmire 1968).
