| Este trabalho foi realizado pela Embrapa Cerrados em uma fazenda particular, objetivando desenvolver estrategias de suplementacao alimentar de bovinos com Misturas Multiplas. Utilizou-se a ureia como substituto da proteina natural e o milho, como fonte de energia, em B. brizantha cv. Marandu, estabelecida em um Latossolo Vermelho-Escuro, textura argilosa. O experimento foi conduzido durante a seca de 1997 e durou 84 dias. Empregou-se 160 novilho Nelore, com peso medio de 175 kg arranjados em sistemas de pastejo continuo em quatro pastos, em delineamento experimental completamente casualizado, com quatro tratamentos: 1- Sal mineralizado com 38% de superfosfato triplo (Testemunha); 2- Milho triturado 30%, farelo de soja 15%, ureia 10%, sal mineralizado 35%,... |

| Since 1972, several herpes-like virus infections have been reported among different bivalve species around the world. Most of these reports involved larvae or juveniles presenting high mortalities. Two case reports of herpes-like viruses concerned adult oysters, Crassostrea virginica in USA and Ostrea angasi in Australia. Molecular techniques including PCR and in situ hybridization (ISH) have been recently developed to detect the oyster herpesvirus genome. In the present study, 30 Pacific oyster, Crassostrea gigas, adults have been analyzed using three different techniques: PCR, ISH and immunochemistry, in order to detect herpesviruses in asymptomatic individuals. PCR and ISH allowed detection of oyster herpesvirus DNA in 93.3 and 86.6%, respectively, of... |

| The commercial culture of Haliotis tuberculata has recently started in Europe. As abalone is herbivorous, the use of local collected algae as feed may appear advantageous. The nutritional value of eight monospecific seaweed diets was studied using Palmaria palmata (Rhodophyta), filamentous algae, mainly Gracilaria sp. (Rhodophyta), Enteromorpha sp. and Ulva lactuca (Chlorophyta), together with Saccharina latissima, Saccorhiza polyschides, Laminaria digitata and Laminaria hyperborea (Ochrophyta, Phaeophyceae) and a mixed macroalgal diet. An integrative approach consisted in monitoring the seasonal composition changes of these algae in terms of protein, lipid, soluble carbohydrate, fatty acid and amino-acid contents, and to relate it to seasonal growth and... |

| Improvement in the osmoregulation capacity via nutritional supplies is vitally important in shrimp aquaculture. The effects of dietary protein levels on the osmoregulation capacity of the Pacific white shrimp (L. vannamei) were investigated. This involved an examination of growth performance, glutamate dehydrogenase (GDH) and Na+-K+ ATPase mRNA expression,, and GDH activity in muscles and gills. Three experimental diets were formulated, containing 25%, 40%, and 50% dietary protein, and fed to the shrimp at a salinity of 25. After 20 days, no significant difference was observed in weight gain, though GDH and Na+-K+ ATPase gene expression and GDH activity increased with higher dietary protein levels. Subsequently, shrimp fed diets with 25% and 50% dietary... |

| For developing efficient diets, two sets of experiments examined whether the use and allocation of dietary protein can be traced by labelling with stable isotopes (N-15 and C-13) in two culture fish (Oncorhynchus mykiss and Sparus aurata). In the first experiment, natural abundance and tissue distribution of these isotopes were determined, by measuring the delta C-13 and delta N-15 values by isotopic ratio mass spectrometry, in fingerlings (14-17 g) adapted to diets differing in the percentage of fish meal replacement by plant protein sources. For both species, delta N-15 and delta C-13 were greater in tissues with higher protein and lower lipid content. Delta N-15 of diets and tissues decreased as replacement increased, suggesting delta N-15 can be used... |

| Understanding the population dynamics of invasive species, such as the green mussel Perna viridis (Linnaeus, 1758), can aid in explaining the success of newly introduced populations and help predict the potential for spread. During a two-year field study of established populations in the invaded region of southwest Florida, year round gametogenesis and continuous spawning capabilities were observed through histological analysis of mussels collected monthly. This was supported by overall stable energetic reserves as measured through proximal biochemical composition (protein, glycogen and lipid content). However, egg outputs in the summer (6.4 x 10(6) +/- 2.6 x 10(6) eggs / female) were significantly higher than egg outputs of winter-spawned mussels (7.7 x... |

| Adhesion of micro-organisms to surfaces in marine environments leads to biofouling. The deleterious effects of biofilm growth in the marine environment are numerous and include : energy losses due to increased fluid frictional resistance or to increased heat transfer resistance, risk of corrosion induced by micro-organisms, loss of optical properties, quality control and safety problems. Antifouling agents are generally used to protect surfaces from being affected by such a biofilm. These agents are toxic and can be persistent, causing harmful environmental and ecological effects. Moreover, the use of biocides and regular cleaning considerably increase the maintenance costs of marine industries. An improved knowledge of the biofilm adhesion mechanisms is... |

| Reared sea bass were submitted to six stressful situations: hyperoxia with or without hypercapnia, increased stocking density in an open flow or recirculating system, transfer to another tank and nodavirus injection. The potentially negative impact of these factors on the lives of sea bass was investigated by measuring 9 water parameters and 19 fish parameters including total serum protein (TSP). TSP has already been used to evaluate stress. The present study investigates data of previous and new experiments, concentrating on the potential use of TSP as a routine indicator to assess welfare in sea bass reared on fish farms. In the current experiment, oxygen and carbon dioxide were seen to affect levels of TSP, but alterations were too erratic to enable... |

| Flax (Linum usitatissimum) has been used for centuries as a source for oil extraction. In recent years it has attracted considerable interest as a result of studies which attribute potential health benefits to its components, including the prevention of chronic non-communicable diseases. Among these compounds presenting biological activity, alpha-linolenic acid, lignans and soluble fibre are of special interest. Southern Chile has comparative advantages for the cultivation of this crop. Together with its full processing, this crop could strengthen regional industry. The purpose of the present work is to learn how the best use can be made of these compounds, by studying flaxseed and flaxseed cake as sources of compounds of interest for food industry. Oil... |

| Scientific evidence supports flaxseed consumption; however, a large sector of the population is still unaware of the benefits associated to its consumption and its possible applications as functional food ingredient in foodstuffs. Flaxseed is mainly known by its high alpha-linolenic acid content, but it is also a lignan source, soluble fibre and protein, compounds which are biologically active in the prevention of some non-transmissible chronic diseases. Southern Chile has comparative advantages for the cultivation of this crop. Together with its full processing, this crop could strengthen regional industry. The purpose of the present review is to highlight the nutritional properties of flaxseed. |

| Mesobuthus gibbosus (Brullé, 1832) scorpions were collected from the Mugla province in the Aegean region of Turkey and housed in individual boxes. After extraction, the venom composition was analyzed using gel electrophoresis (SDS-PAGE). Interestingly, all scorpion venom samples contained only one protein band (~68 kDa) in common. Two protein bands (30 and 98 kDa) were common in six venom samples and were absent in the other venoms. Furthermore, two different protein bands (28 and 45 kDa) were detected in seven venom samples. This study proposes possible variations in the composition of individual scorpion venom samples collected from the same geographic region, based on the electrophoretic profile. Additional studies will be necessary in order to assess... |
