Antiophidian sera sterility control: topics in perspective BJPS
Santos,Paula Gomes; Santos,Dilvani Oliveira; Seródio,Lilia Ribeiro; Marinho,Rachel de Souza; Rodrigues,Carlos Rangel; Cabral,Lucio Mendes; Pádula,Marcelo de; Sousa,Valéria Pereira de; Castro,Helena Carla.
The aim of this work is to review the most important topics about the antiophidic sera sterility, including obtaining methods, sterilization procedures and clean room control using Vital Brazil Institute (VBI) as an example. Bibliographical research was performed through Medline, Lilacs, PubMed, ISI and the Fundação Oswaldo Cruz - RJ and VBI Libraries, from 1960 to 2009. The antiophidic sera for human use are immunobiologic products produced in Brazil by three national laboratories, including VBI. Due to the parenteral use, these products should be sterile and pyrogen-free, which demands the microbiological control during the whole fabrication process. The sterility and pyrogen tests are important steps to ensure the quality and safety of these...

Bioethanol strains of Saccharomyces cerevisiae characterised by microsatellite and stress resistance BJM
Reis,Vanda Renata; Antonangelo,Ana Teresa Burlamaqui Faraco; Bassi,Ana Paula Guarnieri; Colombi,Débora; Ceccato-Antonini,Sandra Regina.
Abstract Strains of Saccharomyces cerevisiae may display characteristics that are typical of rough-type colonies, made up of cells clustered in pseudohyphal structures and comprised of daughter buds that do not separate from the mother cell post-mitosis. These strains are known to occur frequently in fermentation tanks with significant lower ethanol yield when compared to fermentations carried out by smooth strains of S. cerevisiae that are composed of dispersed cells. In an attempt to delineate genetic and phenotypic differences underlying the two phenotypes, this study analysed 10 microsatellite loci of 22 S. cerevisiae strains as well as stress resistance towards high concentrations of ethanol and glucose, low pH and cell sedimentation rates. The...

Combined replacement of fish meal and oil in practical diets for fast growing juveniles of gilthead sea bream (Sparus aurata L.): Networking of systemic and local components of GH/IGF axis ArchiMer
Benedito Palos, L; Saera Vila, A; Calduch Giner, J; Kaushik, Sadasivam; Perez Sanchez, J.
Growth performance and growth regulatory pathways were examined in juvenile gilthead sea bream fed diets containing largely plant-based ingredients. Four isonitrogenous and isolipidic extruded diets with a low level (20%) of fish meal inclusion were formulated with graded levels of a vegetable oil mixture (17:58:25 of rapeseed: linseed: palm oils) replacing fish oil at 33, 66 and 100% (33VO, 66VO and VO diets). All diets were supplemented with lysine (0.55%) and contained soy lecithin (1%). Daily growth coefficients and feed efficiency over the course of an 11-week trial were almost identical in fish fed the FO, 33VO and 66VO diets. The VO diet reduced feed intake and growth without significant effects in proximate whole body composition, nitrogen or...

Contaminação por mercúrio em sedimento e em moluscos do Pantanal, Mato Grosso, Brasil Zoologia
Vieira,Luiz M.; Alho,Cleber J.R.; Ferreira,Geraldo A.L..
The total level of mercury detected in the sediment and in the tissues of molluscs from the Bento Gomes basin, although low, have shown that the mercury used in the gold mining activities in the Poconé wetlands has contaminated those aquatic habitats in Pantanal. From 69 sediment samples analyzed, 26 % (N = 18) have shown levels ranging from 0.01 to 0.25µg.g-1 of mercury (moist weight). Mercury levels analyzed in 54 samples of mollusc tissues (Ampullaria scalaris Orbigny, 1835; A. canaliculata Lamarck, 1819 and Marisa planogyra Pilsbry, 1933) have shown that 30% (N = 16) were contaminated with levels ranging from 0.02 to 1.16µg.g-1 moist weight. This study shows that the mercury used in digs for gold mining and released into the environment has reached the...

Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of...

Estimate of dietary intake of chloropropanols (3-MCPD and 1,3-DCP) and health risk assessment Ciênc. Tecnol. Aliment.
Arisseto,Adriana Pavesi; Vicente,Eduardo; Furlani,Regina Prado Zanes; Toledo,Maria Cecília de Figueiredo.
Chloropropanols, including 3-monochloropropane-1,2-diol (3-MCPD) and 1,3-dichloropropan-2-ol (1,3-DCP), comprise a group of chemical contaminants with carcinogenic and genotoxic properties. They have been found in a variety of processed foods and food ingredients, such as hydrolyzed vegetable protein, soy sauce, cereal-based products, malt-derived ingredients, and smoked foods. This study aimed to assess the dietary exposure to 3-MCPD and 1,3-DCP in Brazil and verify whether the presence of these substances in foods could represent health risks. The intake was calculated by combining data on food consumption, provided by the Consumer Expenditure Survey 2008-2009, with the levels of contaminant occurrence determined by gas chromatography-mass spectrometry....

Fish life-history traits are affected after chronic dietary exposure to an environmentally realistic marine mixture of PCBs and PBDEs ArchiMer
Horri, Khaled; Alfonso, Sebastien; Cousin, Xavier; Munschy, Catherine; Loizeau, Veronique; Aroua, Salima; Begout, Marie-laure; Ernande, Bruno.
Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants that have been shown to affect fish life-history traits such as reproductive success, growth and survival. At the individual level, their toxicity and underlying mechanisms of action have been studied through experimental exposure. However, the number of experimental studies approaching marine environmental situations is scarce, i.e., in most cases, individuals are exposed to either single congeners, or single types of molecules, or high concentrations, so that results can hardly be transposed to natural populations. In the present study, we evaluated the effect of chronic dietary exposure to an environmentally realistic marine mixture of PCB and...

How can we quantify impacts of contaminants in marine ecosystems? The ICON project ArchiMer
Hylland, Ketil; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Robinson, Craig D.; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Matthew J..
An international workshop on marine integrated contaminant monitoring (ICON) was organised to test a framework on integrated environmental assessment and simultaneously assess the status of selected European marine areas. Biota and sediment were sampled in selected estuarine, inshore and offshore locations encompassing marine habitats from Iceland to the Spanish Mediterranean. The outcome of the ICON project is reported in this special issue as method-oriented papers addressing chemical analyses, PAH metabolites, oxidative stress, biotransformation, lysosomal membrane stability, genotoxicity, disease in fish, and sediment assessment, as well as papers assessing specific areas. This paper provides a background and introduction to the ICON project, by...

Impact of contaminated sediment elutriate on coastal phytoplankton community (Thau lagoon, Mediterranean Sea, France) ArchiMer
Ben Othman, Hiba; Pringault, Olivier; Louati, Hela; Hlaili, Asma Sakka; Leboulanger, Christophe.
Effects of sediment-released contaminants and nitrogen were assessed on phytoplankton communities sampled from Thau lagoon (France, Mediterranean Sea) and one close offshore marine station. Phytoplankton was exposed to sediment elutriate (seawater containing a mix of metals, organic chemicals, and nutrients) or to ammonium enrichment for four days using immersed microcosms exposed to natural conditions of light and temperature. Functional (production - respiration balance) and structural (taxonomy and cell densities) responses of the phytoplankton community were assessed. In the lagoon, both treatments stimulated phytoplankton growth, compare to controls. Conversely in the offshore station, the phytoplankton growth was stimulated only with the sediment...

Integrated chemical and biological assessment of contaminant impacts in selected european coastal and offshore marine areas ArchiMer
Hylland, Ketil; Robinson, Craig D.; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Mattew J..
This paper reports a full assessment of results from ICON, an international workshop on marine integrated contaminant monitoring, encompassing different matrices (sediment, fish, mussels, gastropods), areas (Iceland, North Sea, Baltic, Wadden Sea, Seine estuary and the western Mediterranean) and endpoints (chemical analyses, biological effects). ICON has demonstrated the use of a framework for integrated contaminant assessment on European coastal and offshore areas. The assessment showed that chemical contamination did not always correspond with biological effects, indicating that both are required. The framework can be used to develop assessments for EU directives. If a 95% target were to be used as a regional indicator of MSFD GES, Iceland and offshore...
