Effect of deoxynivalenol on neurotransmitters in discrete regions of swine brain.

Abstract: The effect of deoxynivalenol (DON, vomitoxin) on brain amine levels was investigated in swine. DON, a trichothecene mycotoxin, causes suppression of feed intake (anorexia) in susceptible species. Following acute administration of DON to pigs (0.25 mg/kg, IV), concentrations of endogenous catecholamines norepinephrine (NE), dopamine (DA), 3,4-dihydroxyphenyl-acetic acid (DOPAC), and homovanillic acid (HVA), and the indoleamines, 5-hydroxytryptamine (5HT, serotonin) and 5-hydroxyindoleacetic acid (5HIAA) were determined in five brain regions, periodically during the 24 h post-dosing. Analysis was carried out by high performance liquid chromatography, using electrochemical detection.

Schooling behaviour of arctic cod, Boreogadus saida, in relation to drifting pack ice

Abstract: Concentrations of arctic cod were detected with a hydroacoustic system in Resolute Bay, NWT during 2 weeks in August of 1986. Fish biomass within the bay was about 30 t. The fish were feeding primarily on amphipods, which were abundant. When the daily location of the schools was examined in relation to the extent and position of drifting pack ice, a pattern emerged suggesting that the distribution of the fish was influenced by the amount and location of ice cover. If the bay was relatively ice-free, the density of schooling cod was high and the size of the schools, as 2-dimensional surface area, was generally small. When ice covered the bay, density within the schools was lower and they occupied more area. Arctic cod were most dispersed after the bay had been filled with pack ice for several days. It is postulated that this behaviour is a response to potential predation by seabirds and marine mammals.

Provincial Credit Ratings in Canada: An Ordered Probit Analysis

Abstract: L'auteure utilise la methode des probits ordonnes pour estimer les relations entre les cotes de solvabilite octroyees aux provinces par Standard & Poor's et un certain nombre de variables economiques. Les resultats s'averent significatifs dans le cas de toutes les variables estimees. En particulier, l'auteure constate, sur la foi d'un echantillon regroupant les donnees de neuf provinces, que les declassements se produisent a peu pres au meme rythme a differents niveaux du ratio de la dette au PIB.
