Transport through lipids and aquaporins is osmotic and entirely driven by the difference in osmotic pressure. Water transport in cotransporters and uniporters is different: Water can be cotransported, energized by coupling to the substrate flux by a mechanism closely associated with protein.

1977
The whole field of water transport in cells and tissues was recently reviewed in an extensive and scholarly manner by House (1974). The content of the present chapter is much more modest being mostly limited to the phenomenological description of water transport across membranes by the methods of steady-state thermodynamics (see p.

Transport of Water in Small Pores
Langmuir, 2009Experimental measurements of the thermal expansion coefficient (alpha), permeability (k), and diffusivity (D) of water and 1 M solutions of NaCl and CaCl(2) are interpreted with the aid of molecular dynamics (MD) simulations of water in a 3 nm gap between glass plates.

Intestinal Transport of Salt and Water
Clinical Science, 1978Of the developments which have occurred in this field in the last few years, several stand out. The importance of a 'shunt' pathway for ion transport, which passes between rather than through, the epithelial cells, and its role in determining the differing transport characteristics of jejunum, ileum and colon has been recognized.

Ion Transport and Water Movement
Journal of Dental Research, 1987Secretion of water and electrolytes in salivary glands occurs by a dual process involving the formation of a plasma-like, isotonic primary-secretion in salivary acini and its subsequent modification in salivary-ducts by the removal and addition of specific ions.

Molecular aspects of water transport
Pediatric Nephrology, 1992Due to its fundamental importance, the movement of water across cell membranes has been an active area of research for more than 100 years. This subject is central to consideration of normal water metabolism by terrestrial animals, as well as derangements in overall water balance that are frequently encountered by nephrologists in the care of their ...

The mechanism of water transport in membranes
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1977Abstract Biological membranes, lipid membranes and organic polymer membranes have some chemical similarities. All can transport water and it is likely that the molecular transport processes have some common features in the three types of system.

WATER CHANNELS AND UREA TRANSPORTERS
Clinical and Experimental Pharmacology and Physiology, 1997SUMMARY1. It now appears that when water crosses an endothelium which is not fenestrated, or an epithelium with tight junctions, it does so rapidly, and with low energy cost, only if the cell membrane contains an adequate number of specific water channels, encoded by one of at least six different genes.2.

Relation of Water Power to Transportation
Transactions of the American Institute of Electrical Engineers, 1916The paper discusses the relative importance of water power in its relation to transportation, as depending upon its cost and the cost of competing steam power. Proportion which `` Cost of Fuel for Locomotives '' in the country as a whole, in various sections, and in the case of a number of different railroads, bears to `` Total Cost of Operation ...
