    Notes: Abstract  The 5-HT3 receptor is thought to play a role in the reward pathway and the phenomena of drug abuse by modulating dopamine release in the mesolimbic pathway. Studies involving this receptor have been hampered due to the low level of 5-HT3 receptors in the CNS. A 5-HT3 receptor over-expressing mouse was produced to study the role of this receptor in the rewarding properties of drugs of abuse. Over-expression was restricted to the forebrain by controlling gene expression with the Ca2+ calmodulin (CAM) kinase IIα promoter. No over-expression was detected in other body organs nor the cerebellum, as measured by ligand binding and Northern analysis. 5-HT3 receptor over-expressing mice drank less alcohol than non-transgenic mice in a two-bottle free choice test. Over-expression of the 5-HT3 receptor in these mice resulted in a decrease in ethanol consumption. These mice should prove useful in testing hypothesis regarding a common reward pathway for drugs of abuse and the role 5-HT3 receptors play in this pathway.

    Notes: Cellulose acetate reverse osmosis membranes, 600-2800 A. thick, have been prepared on glass surfaces by dipping a clean glass plate into a dilute solution of cellulose acetate. After drying, the membranes are floated of onto a water surface and placed on molecular filter supports. Theoretical salt rejections, as calculated from the solution-diffusion model of membrane transport for cellulose acetate, were obtained with imperfection-free membranes.

    Composite membranes for seawater desalination by reverse osmosis (1971)

    Notes: A composite reverse-osmosis membrane has been developed for seawater desalination having a 400-Å semipermeable barrier. The membrane is prepared by directly forming a very thin film of a polymer, generally cellulose triacetate, upon the finely porous surface of a supporting membrane. The composite membrane, capable of desalinating seawater in a single pass, has demonstrated improved flux stability at high pressures over modified membranes currently used to desalinate brackish water.
