Biomimetic water channels: general discussion
Faraday Discussions, 2018An abstract was not provided in the original work, so a preliminary abstract has been prepared as follows. Of the various topics discussed, a few are briefly mentioned below. A focus on biomimetic water channels concerned the formation of G4 quartet hydrogels. It was found that these hydrogels can form with several different monovalent cations (Li+, Na+

Aquaporins: a water channel family
Anatomical Science International, 2002Water channel proteins, aquaporins, are integral membrane proteins serving in the permeation of water and some other small molecules. Eleven isoforms of aquaporins have been identified from various tissues to date. They are expressed in tissue- and cell-specific manners, and are closely related to the specific functions of tissues and cells. Aquaporins

Aquaporins (AQPs) are a family of integral membrane proteins, through which water and other small molecules pass across the lipid bilayer at high capacity. They are ubiquitously present in all five kingdoms of living organisms, consistent with the fundamental significance of water homeostasis for life. Since the discovery of the first aquaporin, AQP-1,

Aquaporin water channels in mammals
Clinical and Experimental Nephrology, 2009Water channels, aquaporins (AQPs), are a family of small integral plasma membrane proteins that primarily transport water across the plasma membrane. There are 13 members (AQP0-12) in humans. This number is final as the human genome project has been completed.

Publisher Summary Water channel is arbitrary in a cell membrane because most channels that transport ions and polar solutes probably also transport some water. Water channel are those pathways that (1) make a substantial contribution to the net water permeability and (2) whose osmotic water permeability, P f , is greater than its diffusional ...

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.

Biomphalaria species in Alexandria water channels
Parasitology International, 2011Of the several species of Biomphalaria snails worldwide that serve as the intermediate host for Schistosoma mansoni, Biomphalaria alexandrina is a species that is indigenous to Egypt. Recently, there has been much debate concerning the presence of Biomphalaria glabrata and the hybrid of the species with Biomphalaria alexandrina. Due to this debate, the

Biophysical properties of epithelial water channels
Biophysical Chemistry, 1997The biophysical models describing the structure of water pores or channels have evolved, during the last forty years, from a pure 'black box' approach to a molecular based proposal. The initial 'sieving pore' in which water and other molecules were moving together was replaced by a more restrictive model, where water is moving alone in a 'single file ...

Single Molecule Channels Water
Chemical & Engineering News Archive, 2012Chinese researchers have made the first nanoscale artificial water channels that selectively transport water across lipid membranes. Such a system could be used for applications such as water purification and desalination. Jun-Li Hou and coworkers at Fudan University, in Shanghai, constructed the channels from single pillar[5]arene molecules with ...

Describes a simple water channel for use with an overhead projector. The channel is run from a water tap and may be used for flow visualisation experiments including the effect of streamlining and elementary building aerodynamics. Cost and ease of construction make it ideal for schools.
