Many important physical, chemical, and biological processes taking place in nanoscopic confined water environments may behave very different from that in bulk. In this paper, we report an unusual nonenzymatic degradation of DNA molecules in the confined water nanofilm on mica substrate. We found that the half-time of DNA in the degradation process in the water nanofilm is about several hours under high RH at temperatures ranging from 10 to 50 °C, which is much faster than that in bulk water, ∼10(11) years at 25 °C. Careful analysis indicated that it was the formation of a water/vapor interface in the water nanofilm that played a major role in promoting DNA degradation.

Drinking water is largely advocated for obesity prevention and management. Recent studies have suggested that water has a thermogenic effect, this has not been examined in children. In thi...
In this study the investigators propose to assess the hemodynamic response to the ingestion of 16 fl oz of water. The investigators will test the hypothesis that water ingestion will incr...
A class of proteins involved in the transport of molecules via TRANSPORT VESICLES. They perform functions such as binding to the cell membrane, capturing cargo molecules and promoting the assembly of CLATHRIN. The majority of adaptor proteins exist as multi-subunit complexes, however monomeric varieties have also been found.
Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.
Electrophoresis in which paper is used as the diffusion medium. This technique is confined almost entirely to separations of small molecules such as amino acids, peptides, and nucleotides, and relatively high voltages are nearly always used.
The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.
