The distribution and chemical phenotypes of hindbrain neurons that are activated in rats after food ingestion were examined. Rats were anesthetized and perfused with fixative 30 min after the end of 1-h meals of an unrestricted or rationed amount of food, or after no meal. Brain sections were processed for localization of the immediate-early gene product(More)
In previous studies we developed a rat model in which demyelination is reproducibly produced following rapid correction of chronic hyponatremia and demonstrated that the development of demyelination in this model is strongly associated with NMR indices of blood-brain barrier (BBB) disruption. Because complement is toxic to oligodendrocytes, we evaluated the(More)
This study evaluated whether renal escape from vasopressin-induced antidiuresis is associated with alterations of vasopressin V2 receptor binding in the kidney inner medulla. A radioligand binding assay was developed using a novel iodinated vasopressin V2 receptor antagonist to analyze vasopressin V2 receptor binding in kidney inner medullary tissue from(More)
Recent results indicate that renal escape from vasopressin-induced antidiuresis is accompanied by a marked downregulation of whole kidney aquaporin-2 (AQP-2) protein and mRNA expression. However, in those studies, the escaped animals were also markedly hypo-osmolar compared to controls as a result of water loading during antidiuresis. The present studies(More)
The associations were quantified between daily and interannual variation in the timing of a closed population of lake sturgeon Acipenser fulvescens migration and arrival at spawning sites with stream environmental and lunar covariates. Spawning data were gathered from 1262 fish in Black Lake, Michigan 2001 to 2008 and by video monitoring 2000 to 2002.(More)
Pflaumen und andere Früchte entwickeln während ihres Fruchtwachstums eine halbtransparente, weißliche Schicht auf ihrer Oberfläche, die als Beduftung oder Duftfilm bezeichnet wird. Die Beduftung auf Pflaumen verschiedener Farbe (Hauszwetsche, Reneclaude, Mirabelle) wurde mit Hilfe eines Rasterelektronen – Mikroskopes, eines Farbmessgerätes und eines(More)
Robotic rovers are expected to play a major role in future lunar in-situ resource prospecting. Prospecting missions will involve a ground control team of planetary scientists and rover operators. These ground controllers will need to evaluate prospecting data gathered by a rover and make operational decisions in real-time. In October 2014, the NASA Ames(More)
