Neurological Effects of Low-Level, Chronic Domoic Acid Exposure in a Nonhuman Primate Model
… risks to human and wildlife populations. Domoic acid (DA), the focus of this dissertation, is produced by algae in the genus Pseudo-nitzschia. DA is a potent glutamate receptor agonist and neurotoxin, and high-dose exposure to this toxin has been associated with severe illness and permanent …

Assessing the impact of domoic acid exposure on the zebrafish (Danio rerio) brain across life stages
Domoic acid (DA) is a neurotoxin produced by diatoms in genus Pseudo-nitzschia. DA accumulates in seafood and can affect the health of humans and wildlife. DA is a structural analog of glutamate - an excitatory neurotransmitter - that activates ionotropic glutamate receptors leading to …

Effects of acidification on the crayfish Cambarus bartonii bartonii in southern Appalachian streams
Population biology and acid tolerance of the crayfish Cambarus bartonii bartonii (Fabricius) from southern Appalachian Mountain streams were investigated. Field studies were conducted primarily from May through October, 1985 at Coweeta Hydrologic Laboratory (U. S. Forest Service Southeastern …

Klinische und funktionelle Langzeitergebnisse nach offener chirurgischer Therapie der gastro-oesophagealen Refluxkrankheit
… sphincters on manometry and increased esophageal acid exposure on 24-hour pH monitoring. The patients either had severe complications of gastroesophageal reflux disease or had failed medical therapy. These requirements have been found to be necessary to ensure a successful surgical outcome. The …

Regulation and desensitisation studies on the nicotinic acid receptors
The lipid-modifying qualities of nicotinic acid, a B3 vitamin, have been exploited for many years to prevent cardiovascular disease and its associated mortality. Despite its widespread availability and clinical use, the clinical target and precise molecular mechanism by which nicotinic acid acts …

Duodenal pH : new aspects of physiology and pathophysiology
… to centre around the presence of gastric acid, yet the exact role that acid plays is poorly understood. Previous investigations of the duodenal pH have been restricted by methodological and technical difficulties, and have, for the most part, only monitored the pH in the short-term. A new …

Significance of nanosilica incorporation in type G oil well cement pastes
… analysis and quantification after carbonic acid exposure testing. Degradation testing was performed by simulating conditions of geosequestration in a sandstone formation at a depth of roughly 1 km. These conditions were created by bubbling CO2 into a heated vessel containing 0.5 M NaCl …

Elucidation of weak organic acid resistance mechanisms in non-Saccharomyces yeast: a case study of Zygosaccharomyces parabailii and Kluyveromyces marxianus
… including bulk chemicals such as organic acids. However, efficient and economically viable production of organic acids has to face problems related to low productivity/titer and toxicity of the final product. Therefore, the exploration of yeast biodiversity to exploit unique native …

Surface modification of polymer membranes by self-organization
… self-healing, in that surface layers damaged by acid exposure can be largely regenerated by subsequent heat treatment in water, which results in further surface segregation of residual comb from the bulk. Using a novel, industrially-relevant atom transfer radical polymerization technique, comb …
