    A histopathological screening was performed on juvenile Senegalese soles exposed to environmentally realistic concentrations of waterborne Cd (0.5, 5 and 10 lg L-1 ) for 28 days. The severity and dissemination of histopathological changes were variable and limited to the kidney, liver, spleen, gills and skin goblet cells. Contradicting available literature that refers the liver as the most affected organ upon acute exposure and the kidney following chronic exposure, the liver was the most impacted organ (even at the lowest concentration), in a trend that could relate to the duration of exposure and Cd concentration. The most noticeable hepatic alterations related to inflammation, although hepatocellular alterations like lipidosis and eosinophilic foci also occurred. The trunk kidney of exposed fish endured moderate inflammation, apoptosis and necrosis, however, without a clear time-dependent effect. The spleen of fish subjected to the highest concentrations revealed diffuse necrotic foci accompanied by melanomacrophage intrusion. The gills, albeit the most important apical uptake organ of dissolved toxicants, sustained only moderate damage, from epithelial hyperplasia and pavement cell detachment to the potentially more severe chloride cell alterations. In the skin, an increase in goblet cell size occurred, most notoriously correlated to Cd concentration at earlier stages of exposure. The results show that a metal-naı¨ve juvenile fish can endure deleterious effects when exposed to low, ecologically relevant, concentrations of a common toxic metal and that the pattern of Cdinduced histopathological alterations can be complex and linked to organ-specific responses and metal translocation within the organism.info:eu-repo/semantics/publishedVersio

    An integrative assessment to determine the genotoxic hazard of estuarine sediments: combining cell and whole-organism responses

    Get PDF
    The application of the Comet assay in environmental monitoring remains challenging in face of the complexity of environmental stressors, e.g., when dealing with estuarine sediments, that hampers the drawing of cause-effect relationships. Although the in vitro Comet assay may circumvent confounding factors, its application in environmental risk assessment (ERA) still needs validation. As such, the present work aims at integrating genotoxicity and oxidative DNA damage induced by sediment-bound toxicants in HepG2 cells with oxidative stress-related effects observed in three species collected from an impacted estuary. Distinct patterns were observed in cells exposed to crude mixtures of sediment contaminants from the urban/industrial area comparatively to the ones from the rural/riverine area of the estuary, with respect to oxidative DNA damage and oxidative DNA damage. The extracts obtained with the most polar solvent and the crude extracts caused the most significant oxidative DNA damage in HepG2 cells, as measured by the formamidopyrimidine-DNA glycosylase (FPG)-modified Comet assay. This observation suggests that metals and unknown toxicants more hydrophilic than polycyclic aromatic hydrocarbons may be important causative agents, especially in samples from the rural part of the estuary, where oxidative DNA damage was the most significant. Clams, sole, and cuttlefish responded differentially to environmental agents triggering oxidative stress, albeit yielding results accordant with the oxidative DNA damage observed in HepG2 cells. Overall, the integration of in vivo biomarker responses and Comet assay data in HepG2 cells yielded a comparable pattern, indicating that the in vitro FPG-modified Comet assay may be an effective and complementary line-of-evidence in ERA even in particularly challenging, natural, scenarios such as estuarine environments

    Cultivating the macroalgal holobiont: effects of integrated multi-trophic aquaculture on the microbiome of Ulva rigida (chlorophyta)

    Ulva is a ubiquitous macroalgal genus of commercial interest. Integrated Multi-Trophic Aquaculture (IMTA) systems promise large-scale production of macroalgae due to their high productivity and environmental sustainability. Complex host-microbiome interactions play a decisive role in macroalgal development, especially in Ulva spp. due to algal growth- and morphogenesis-promoting factors released by associated bacteria. However, our current understanding of the microbial community assembly and structure in cultivated macroalgae is scant. We aimed to determine (i) to what extent IMTA settings influence the microbiome associated with U. rigida and its rearing water, (ii) to explore the dynamics of beneficial microbes to algal growth and development under IMTA settings, and (iii) to improve current knowledge of host-microbiome interactions. We examined the diversity and taxonomic composition of the prokaryotic communities associated with wild versus IMTA-grown Ulva rigida and surrounding seawater by using 16S rRNA gene amplicon sequencing. With 3141 Amplicon Sequence Variants (ASVs), the prokaryotic richness was, overall, higher in water than in association with U. rigida. Bacterial ASVs were more abundant in aquaculture water samples than water collected from the lagoon. The beta diversity analysis revealed distinct prokaryotic communities associated with Ulva collected in both aquacultures and coastal waters. Aquaculture samples (water and algae) shared 22% of ASVs, whereas natural, coastal lagoon samples only 9%. While cultivated Ulva selected 239 (8%) host-specific ASVs, wild specimens possessed more than twice host-specific ASVs (17%). Cultivated U. rigida specimens enriched the phyla Cyanobacteria, Planctomycetes, Verrucomicrobia, and Proteobacteria. Within the Gammaproteobacteria, while Glaciecola mostly dominated the microbiome in cultivated algae, the genus Granulosicoccus characterized both Ulva microbiomes. In both wild and IMTA settings, the phylum Bacteroidetes was more abundant in the bacterioplankton than in direct association with U. rigida. However, we observed that the Saprospiraceae family within this phylum was barely present in lagoon water but very abundant in aquaculture water. Aquaculture promoted the presence of known morphogenesis-inducing bacteria in water samples. Our study suggests that IMTA significantly shaped the structure and composition of the microbial community of the rearing water and cultivated U. rigida. Detailed analysis revealed the presence of previously undetected taxa associated with Ulva, possessing potentially unknown functional traits.European Union (EU)642575; German Research Foundation (DFG) CRC 1127 ChemBioSys;COST Action "Phycomorph" FA1406info:eu-repo/semantics/publishedVersio

    Benthic meiofauna as indicator of ecological changes in estuarine ecosystems: The use of nematodes in ecological quality assessment

    Get PDF
    a b s t r a c t Estuarine meiofauna communities have been only recently considered to be good indicators of ecological quality, exhibiting several advantages over macrofauna, such as their small size, high abundance, rapid generation times and absence of a planktonic phase. In estuaries we must account not only for a great natural variability along the estuarine gradient (e.g. sediment type and dynamics, oxygen availability, temperature and flow speed) but also for the existence of anthropogenic pressures (e.g. high local population density, presence of harbors and dredging activities). Spatial and temporal biodiversity patterns of meiofauna and freeliving marine nematodes were studied in the Mondego estuary (Portugal). Both taxonomic and functional approaches were applied to nematode communities in order to describe the community structure and to relate it with the environmental parameters along the estuary. At all sampling events, nematode assemblages reflected the estuarine gradient, and salinity and grain size composition were confirmed to be the main abiotic factors controlling the distribution of the assemblages. Moreover, the low temporal variability may indicate that natural variability is superimposed by the anthropogenic pressures present in some areas of the estuary. The characterization of both meiofauna and nematode assemblages highlighted the usefulness of the integration of both taxonomic and functional attributes, which must be taken into consideration when assessing the ecological status of estuaries

    Get PDF
    The aim of this study was to evaluate the reliability of four scales of pain intensity measurement in patients with musculoskeletal disorders and low educational level. Verbal rating scale, face scale, visual analogy scale, and numeric scale were used. Reliability was evaluated by the stability (test-retest) using Intraclass Correlation Coefficient, and the participant’s perception on understanding and completing the scale forms. Numerical scale presented the highest reliability value (r = 0,99), and verbal rating scale, had the lowest reliability value (r = 0,88). The numerical scale was considered the easiest to understand and to complete, while the most difficult was the visual analogy scale

    Cinema brasileiro e o mito “Rio de Janeiro: a cidade maravilhosa”

    Esse trabalho discute a representação do “mito” da cidade maravilhosa atribuído à cidade do Rio de Janeiro através de uma reflexão sobre a produção cinematográfica brasileira contemporânea e a criação de novos paradigmas de representação e entendimento da identidade cultural brasileira. Trata-se aqui também do conceito de produção do espaço por meio da análise da representação fílmica do Rio de Janeiro no filme O Homem do Ano (The Man of the Year, José Guilherme Fonseca, 2002). Esse filme discute de forma genérica sobre vários elementos relacionados ao entendimento da vida urbana brasileira contemporânea e sua identidade cultural comentando sobre conceitos e discussões do tipo: a cidade da imaginação; a cidade como produto de certa instabilidade em relação à problemática do conceito de identidade e sua relação confusa com/no tempo e espaço; a cidade que comporta a representação imagética de todo o país; e, finalmente, a cidade que combina dois polos opostos: a cidade como um espaço moderno e civilizado e a cidade tradicional do espaço primitivo.This paper will discuss the representation of the “myth” of the marvelous city attributed to the Brazilian city of Rio de Janeiro by looking at the contemporary Brazilian film production and its creation of new paradigms for representing and understanding Brazilian cultural identity. It will also comment on the concept of production of space through the analysis of the cinematic representation of Rio de Janeiro in the film The Man of the Year (O Homem do Ano, José Guilherme Fonseca, 2002). This film generally touches on many relevant matters related to the understanding of contemporary Brazilian urban life and cultural identity commenting on the concepts and discussion such as: the city of imagination; the city as a product of a certain cultural uneasiness in relation to current concerns about identity and its confusing relationship to time and space; the city as embodying the notion of an entire country imagery; and finally, the city combining two opposing poles: the city as a civilized and modern space and the city as a traditional and primitive space
