    Notes: Abstract Studies on the alternative complement pathway (ACP) activity in fish have suggested the particular relevance of this pathway as a non-specific immune mechanism being its activation directly related with the availability of certain nutrients. In the present study ACP activity in gilthead seabream fed different dietary levels of a-tocopherol and n-3 HUFA deficiencies was studied under different stress conditions (overcrowding and repetitive chasing). A reduction in ACP activity was found when diets with deficiencies in α-tocopherol and n-3 HUFA were assayed at any of the experimental conditions assayed. Levels of plasma cortisol were similar to those of fish after crowding stress subjected to dietary deficiencies at low stocking density, suggesting that dietary deficiencies produced a chronic elevation of cortisol. When fish were subjected to repetitive chasing, plasma cortisol from fish fed control diet showed a progressive increase whereas plasma cortisol levels from both dietary deficient groups showed a transitory peak 4 days after the beginning of the repetitive chasing. However, ACP activity levels of fish fed deficient diets remained lower than the control group and constant during chasing period. These results suggest that both a-tocopherol and n-3 HUFA nutritional deficiencies rather than stress are an important determinant of fish complement activity.

    Dopamine controls persistence of long-term memory storage (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-08-22
    Description: The paradigmatic feature of long-term memory (LTM) is its persistence. However, little is known about the mechanisms that make some LTMs last longer than others. In rats, a long-lasting fear LTM vanished rapidly when the D1 dopamine receptor antagonist SCH23390 was injected into the dorsal hippocampus 12 hours, but not immediately or 9 hours, after the fearful experience. Conversely, intrahippocampal application of the D1 agonist SK38393 at the same critical post-training time converted a rapidly decaying fear LTM into a persistent one. This effect was mediated by brain-derived neurotrophic factor and regulated by the ventral tegmental area (VTA). Thus, the persistence of LTM depends on activation of VTA/hippocampus dopaminergic connections and can be specifically modulated by manipulating this system at definite post-learning time points.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rossato, Janine I -- Bevilaqua, Lia R M -- Izquierdo, Ivan -- Medina, Jorge H -- Cammarota, Martin -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):1017-20. doi: 10.1126/science.1172545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro de Memoria, Instituto do Cerebro, Pontificia Universidade Catolica do Rio Grande do Sul, Porto Alegre, Brazil.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19696353" target="_blank"〉PubMed〈/a〉
