MIZUMORI, Sheri J.Y.: A neural systems analysis of adaptive navigation in rodents The hippocampus is thought to be critical for adaptive navigation since hippocampal lesions produce deficits in visual spatial learning, and hippocampal neurons fire relative to an animal’s location in space. Hippocampal ‘place cells’ are thought to contribute to a place code that is […]

SHERIDAN, Mark A.; KITTILSON, Jeffrey D.; North Dakota State University; North Dakota State University: The Role of Somatostatins in the Regulation of Metabolism Somatostatins (SSs) are a structurally and functional diverse family of peptide hormones. Among the vast array of biological functions coordinated by the SSs are secretotropic effects as well as a host of […]

HOULIHAN, D.F; MARTIN, S.A.M.; University of Aberdeen: Protein metabolism in fish; gambling on proteomics. Protein metabolism in animals involves a balance between protein synthesis and degradation resulting in net gain or loss of proteins in an organism. Although protein synthesis is stimulated by feeding and growth is correlated with an increase in protein synthesis, rates […]

SILVERSTEIN, JT; USDA-ARS-NCCCWA: Neurohormonal regulation of feeding in fish There is extraordinary diversity in life histories of fish with regard to feeding, for example the prolonged periods of fasting in salmon and lamprey contrasted with periods of extreme prespawning consumption in some teleosts such as scorpaenids. In addition to life history programming, feed intake is […]

MOMMSEN, T.P.; BUSBY, E.R.; Univ. of Victoria; Univ. of Victoria: Hormones regulating glucose metabolism: the good and the ugly (without the bad) Even though plasma glucose in fishes may not be as tightly controlled as in mammals, numerous hormones interact to regulate piscine glucose metabolism. The presentation will review the specific metabolic roles, sites of […]

BUDDINGTON, RK; KROGDAHL, A; Mississippi State University; Norwegian College of Veterinary Medicine: Hormonal Regulation of the Gastrointestinal Tract of Fish The gastrointestinal tract (GIT) of fish and other vertebrates is challenged with a diversity of functional demands that are associated with changes and differences in dietary inputs and environmental conditions. Many of the hormones, associated […]

VIJAYAN, M.M.; SATHIYAA, R.; University of Waterloo; University of Waterloo: Autoregulation of glucocorticoid receptor by cortisol in rainbow trout hepatocytes Glucocorticoids play an important role in the stress response and glucocorticoid receptor (GR) regulation may be a key process in the physiological response to regain homeostasis. We used primary cultures of rainbow trout hepatocytes and […]

TAYLOR, B.E.; DEBIASE, A.E.; Univ. of Georgia, SREL, Aiken; Univ. of Georgia, SREL, Aiken: Why are there so many calanoid copepods in temporary ponds of southeastern North America? At least fourteen species of calanoid copepods are known from temporary ponds on the Coastal Plain in South Carolina, USA, and additional species have been reported elsewhere […]

WILLIAMS, Judith L.; Univ. of Southern Miss Gulf Coast: What determines lipid content in copepods preparing for long-term dormancy? The storage of lipids prior to dormancy is a widespread phenomenon in animals that diapause or hibernate. Lipid class and fatty acid content are highly variable, even within members of the same genus. Copepods undergo long […]
