Digestive and metabolic consequences of on-growing greater amberjack (Seriola d...
Navarro-Guillén, C.; Perera, E.; Pérez-Hilario, D.; Martos-Sitcha, J.A.; Molina-Roque, L.; Gregorio, Silvia; Fonseca, Filomena; Fuentes, J.; Yúfera, M.Aiming to elucidate the effects of temperature on different aspects of the fish digestive physiology that may affect the growth, we examined, firstly, variations in growth performance, feed intake, digestive enzyme activities, expression of transport related genes, metabolites in plasma and liver, and oxidative stress response in juveniles of greater amberjack (Seriola dumerili) growing during two months at 18,...
Effect of bile salts on intestinal epithelial function in gilthead seabream (Sp...
Fuentes, J.; Gregorio, Silvia; F. Fonseca; Robles-Arozarena, R.; Martos-Sitcha, J. A.; Moyano, F. J.In the context of modern aquaculture, the effort to reduce the reliance on fishmeal/marine ingredients in fish diets has led to the exploration of plant-based protein sources as potential substitutes, a dietary shift that disrupts the bile acid profile in fish. Therefore, bile salts are being sought as additives. However, artificially increased intestinal levels of bile acids may significantly impact mucosal fu...
Contrasting convective regimes over the Amazon: Implications for cloud electrif...
Williams, E.; Rosenfeld, D.; Madden, N.; Gerlach, J.; Gears, N.; Atkinson, L.; Dunnemann, N.; Frostrom, G.; Antonio, M.; Biazon, B.; Camargo, R.Made available in DSpace on 2022-04-29T08:44:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2002-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); National Aeronautics and Space Administration; Four distinct meteorological regimes in the Amazon basin have been examined to distinguish the contributions from boundary layer aerosol and convective available potential energy (CAPE) to conti...
Tissue and salinity specific Na+/Cl− cotransporter (NCC) orthologues involved i...
Barany, A.; Shaughnessy, C. A.; Pelis, R. M.; Fuentes, J.; Mancera, J. M.; McCormick, S. D.Two orthologues of the gene encoding the Na+-Cl− cotransporter (NCC), termed ncca and nccb, were found in the sea lamprey genome. No gene encoding the Na+-K+-2Cl cotransporter 2 (nkcc2) was identifed. In a phylogenetic comparison among other vertebrate NCC and NKCC sequences, the sea lamprey NCCs occupied basal positions within the NCC clades. In freshwater, ncca mRNA was found only in the gill and nccb only in...
Dietary aflatoxin B1 (AFB1) reduces growth performance, impacting growth axis, ...
Barany, A.; Guilloto, M.; Cosano, J.; de Boevre, M.; Oliva, M.; de Saeger, S.; Fuentes, J.; Martinez-Rodriguez, G.; Mancera, J. M.Mycotoxins are an increasing threat to all the related commodities from agriculture. Its occurrence is expected to increase due to climate change. Here, we examined the impacts of dietary toxicity of aflatoxin B1 (AFB1) in gilthead sea bream (Sparus aurata) at levels of 1 or 2 mg AFB1 kg(-1)- fish feed. Inclusion of AFB1 in the diet resulted in 80% inhibition of the total weight gain during the 85-day trial. Ca...
ASD prevalence study across Europe: developing a school-based screening approac...
García Primo, P.; Schendel, D.; Partner, E.; Rasga, C.; Café, C.; Rogé, B.; Arnaud, C.; Saemundsen, E.; Muratori, F.; Narzisi, A.; Boilson, A.Objectives: The main objective of the present work is to describe the strategy of the Autism Spectrum Disorder in the European Union (ASDEU) project to estimate the prevalence of ASD in school-aged children (7-9 years) across Europe. The focus of the presentation is on the novel field study strategy and aims to be a reflection on what we have learned regarding standardization of study methods across sites, what...
Use of early intervention for young children with autism spectrum disorder acro...
Salomone, E.; Beranová, Š.; Bonnet-Brilhault, F.; Briciet Lauritsen, M.; Budisteanu, M.; Buitelaar, J.; Canal-Bedia, R.; Felhosi, G.Little is known about use of early interventions for autism spectrum disorder in Europe. Parents of children with autism spectrum disorder aged 7 years or younger (N = 1680) were recruited through parent organisations in 18 European countries and completed an online survey about the interventions their child received. There was considerable variation in use of interventions, and in some countries more than 20% ...
DAX1 regulatory networks unveil conserved and potentially new functions
Martins, Rute S. T.; Power, Deborah; Fuentes, J.; Deloffre, Laurence A. M.; Canario, Adelino V. M.DAX1 is an orphan nuclear receptorwith actions in mammalian sex determination, regulation of steroidogenesis, embryonic development and neural differentiation. Conserved patterns of DAX1 gene expression frommammals to fish have been taken to suggest conserved function. In the present study, the European sea bass, Dicentrarchus labrax, DAX1 promoter was isolated and its conserved features compared to other fish ...
AVT is involved in the regulation of ion transport in the intestine of the sea ...
Martos-Sitcha, J. A.; Gregorio, Silvia; Carvalho, Edison Samir Mascarelhas; Canario, Adelino V. M.; Power, Deborah; Mancera, J. M.The intestine of marine fish plays a crucial role in ion homeostasis by selective processing of ingested fluid. Although arginine vasotocin (AVT) is suggested to play a role in ion regulation in fish, its action in the intestine has not been demonstrated. Thus, the present study investigated in vitro the putative role of AVT in intestinal ion transport in the sea bream (Sparus aurata). A cDNA encoding part of a...
Adaptation to different salinities exposes functional specialization in the int...
Gregorio, Silvia; Carvalho, Edison Samir Mascarelhas; Encarnação, Sandra; Wilson, J.; Power, Deborah; Canario, Adelino V. M.; Fuentes, J.The processing of intestinal fluid, in addition to a high drinking rate, is essential for osmoregulation in marine fish. This study analyzed the long-term response of the sea bream (Sparus aurata L.) to relevant changes of external salinity (12, 35 and 55p.p.t.), focusing on the anterior intestine and in the less-often studied rectum. Intestinal water absorption, epithelial HCO3– secretion and gene expression ...
