Description: This presentation is part of the faculty lecture series UNT Speaks Out on the 2012 Presidential Primaries. In this presentation, the author gives the audience an overview of the structure of the primaries, and provides a recap of past primaries. The author also speaks about the money, momentum, and media attention in the primaries.

Description: This article discusses Abraham model correlations for the transfer of neutral molecules and ions to sulfolane. Data have been compiled from the published literature on the partition coefficients of solutes and vapors into anhydrous sulfolane. The logarithms of the water-to-sulfolane partition coefficients, log P, and gas-to-sulfolane partition coefficients, log K, were correlated with the Abraham solvation parameter model. The derived correlations described the observed log P and log K values for solutes dissolved in sulfolane to within average standard deviations of 0.14 log units or less. The log P correlation was extended to include the partition of ions by inclusion of a cation-solvent and an anion-solvent term.

Description: This paper discusses research on acetylcholine-containing neuroepithelial cells in fish gills. Abstract: The neurochemical link between O2 chemoreceptors and afferent nerves that carry information about O2 levels to cardio-ventilatory centers in the brain has yet to be determined. This study examines the roles of two candidate neurotransmitters thought to be involved in O2 chemoreception, using channel catfish, Ictalurus punctatus. Fish gills are the evolutionary progenitors of arterial arches (aortic and carotid) of mammals where O2 chemoreceptors are located. Neuroepithelial cells (NECs) containing serotonin (5-HT) and acetylcholine (Ach) were confirmed in the first gill arch using immunohistochemistry and laser confocal microscopy. 5-HT-containing NECs were aggregated around the efferent branchial artery, near tips of filaments and lamellae, ACh-containing NECs at the distal tips of filaments. Preliminary co-localization experiments indicate separate 5-HT and Ach-containing cells. This is the first demonstration of ACh-containing NECs and results of this study support pharmacological studies suggesting that ACh is the primary neurochemical involved in O2 chemoreception in vertebrates.
