Avaliação da bioacessibilidade de carotenoides em suco de melancia e produtos processados. Repositório Alice
CONSTANT, L. S.; GOMES, F. dos S.; RIBEIRO, A. P. de O.; GODOY, R. L. de O.; CABRAL, L. M. C..
Conhecida por suas agradáveis características sensoriais, a melancia é um fruto muito apreciado para consumo in natura. Ultimamente, tem sido relatada como uma importante fonte de licopeno, um pigmento associado à redução do risco de algumas doenças degenerativas. Diversos processos tem apresentado eficácia em concentrar e aumentar a estabilidade do licopeno a partir de frutas. Entretanto, tal incremento no teor desse composto não, necessariamente, implica em um aumento na quantidade absorvida pelo organismo humano e, consequentemente, na promoção da saúde do indivíduo de forma que a avaliação da liberação do composto durante a digestão, ou seja, a sua bioacessibilidade se faz necessária. Este trabalho objetivou adaptar um modelo de digestão in vitro para...

Chronic dietary exposure to pyrolytic and petrogenic mixtures of PAHs causes physiological disruption in zebrafish - part I: Survival and growth ArchiMer
Vignet, Caroline; Le Menach, Karyn; Mazurais, David; Lucas, Julie; Perrichon, Prescilla; Le Bihanic, Florane; Devier, Marie-hélène; Lyphout, Laura; Frere, Laura; Begout, Marie-laure; Zambonino-infante, Jose Luis; Budzinski, Helene; Cousin, Xavier.
The release of polycyclic aromatic hydrocarbons (PAHs) into the environment has increased very substantially over the last decades leading to high concentrations in sediments of contaminated areas. To evaluate the consequences of long-term chronic exposure to PAHs, zebrafish were exposed, from their first meal at 5 days post fertilisation until they became reproducing adults, to diets spiked with three PAH fractions at three environmentally relevant concentrations with the medium concentration being in the range of 4.6–6.7 μg g−1 for total quantified PAHs including the 16 US-EPA indicator PAHs and alkylated derivatives. The fractions used were representative of PAHs of pyrolytic (PY) origin or of two different oils of differing compositions, a heavy fuel...

Cycles saisonniers, reproduction et qualite des ovocytes chez Pecten maximus en rade de Brest ArchiMer
Paulet, Yves-marie; Bekhadra, Farida; Devauchelle, Nicole; Donval, Anne; Dorange, Germaine.
This work is part of the program, "recruitment determinism in scallops" initiated in 1992 by the "Contrat de Baie". The aim of this research was to explain interannual abundance fluctuations observed for Pecten maximus, in the Bay of Brest. To this end an analytical approach to the life cycle of the species was undertaken to determine its critical phases. A phase may be considered as "critical" if the mortality rate at its level varies from one year to the other. Using data from 1989 to 1994, a precise time-table of the "physiological year" of the scallop in the Bay of Brest was determined. Fecundity and gamete production kinetics were estimated from the annual variation in the weight indices of the gonad. In the laboratory, egg quality was estimated...

Dietary neutral lipid level and source in marine fish larvae: Effects on digestive physiology and food intake ArchiMer
Morais, Sofia; Conceicao, L; Ronnestad, I; Koven, W; Cahu, Chantal; Zambonino, Jose-luis; Dinis, M.
A growth depressing effect of high dietary neutral lipid levels in marine fish larvae has been reported. This may be a result of a decrease in the efficiency or activity of digestive enzymes, a reduction in absorption efficiency and/or a decrease in food intake. The present work reviews recent studies carried out on commercially valuable species (Atlantic herring, Senegalese sole, European seabass and gilthead seabream) that investigated the effects of neutral lipid level and lipid source (fatty acid composition) on some of these key factors influencing larval growth. The results seem to collectively indicate that lipid transport from the enterocytes into the body may be more problematic in larval stages dealing with high neutral lipid diets than lipolytic...

Dynamique et enzymologie de la digestion chez l'huitre Crassostrea gigas ArchiMer
Boucaud, C; Lebesnerais, C; Lubet, P; Lihrmann, I.
Feeding experiments carried out on Crassostrea gigas allowed the authors to set up the stages and the timing of the movement of food throughout the digestive tract. Various activities involved in digestion (glycosidases, esterases, and peptidases) were investigated histochemically in the digestive tract in order to localize the sites of absorption and the sites of protein and carbohydrate digestion. An explicative model of the different stages of digestion is proposed.

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives ArchiMer
Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Evaluation in situ digestibility of alfalfa in different grinds and textiles Animal Sciences
Kuwahara, Frank Akiyoshi; Souza, Gilberto Batista de; Ferreira, Reinaldo de Paula; Costa, Ciniro; Meirelles, Paulo Roberto de Lima.
Indigestible fractions of dry matter (iDM) and neutral detergent fiber (iNDF) in the feed of ruminants are mainly estimated by in situ incubation time with regard to particle size and textile types. Samples of alfafa, ground into three particle sizes, were analyzed. Samples, processed in a Willey mill with 1.0; 2.0 and 3.0 mm sieve pores, were conditioned in F57 (Ankon®), nonwoven (100 g m-2) and polyester textile bags measuring 4 x 5 cm. Material was divided into 13 incubation periods and 8 replications, and incubated in the rumen of two multiparous cows adapted to a 70:30 diet, roughage:concentrate, respectively, for 288h. iDM and iNDF rates were evaluated sequentially for non-digested percentage and data underwent analysis of variance (ANOVA p <...

Gene expression pattern of digestive and antioxidant enzymes during the larval development of reared Atlantic bluefin tuna (ABFT), Thunnus thynnus L. ArchiMer
Mazurais, David; Coves, Denis; Papandroulakis, Nikos; Ortega, Aurelio; Desbruyeres, Elisabeth; Huelvan, Christine; Le Gall, Marie-madeleine; De La Gandara, Fernando; Cahu, Chantal.
The aim of this study was to determine whether mortality observed during the larval development of reared bluefin tuna (Thunnus thynnus) could be related to improper expression profiles of key genes involved in digestive or antioxidant response capabilities. Tuna larvae were sampled at hatching, 2, 5, 10, 15 and 20 dph (days post hatching) for the relative quantification of transcripts encoded by genes involved in digestive [trypsinogen 1 (TRYP1), alpha-amylase (AMY), aminopeptidase N (ANPEP)] and antioxidant [catalase (CAT)] functions. The levels of expression of ANPEP related to the development and maturation of intestinal function increased from 5 to 20 dph. Furthermore, AMY and TRYP1 genes, which are pancreatic enzymes implicated in carbohydrate and...

Growth factors in Penaeid shrimp feeding ArchiMer
Guillaume, Julien; Cruz, R; Cuzon, Gerard; Wormhoudt Van, A; Revol, A.
Some nutrients known as non essential in vertebrates could be essential in invertebrates and could be related to some "unknown growth factors" which were evidenced or suspected, mainly in mollusc or crustacean flesh or meal, by several authors working on different species of crustaceans. A set of experiments was carried out in our laboratory in order to isolate one of these factors found in squid meal.
