    Folic Acid (FA) supplementation during pregnancy represents a so widespread and established recommendation all over the world, to be taken for granted sometimes. As a matter of fact, this vitamin supplement is worldwide recommended mostly during peri-conceptional period for its proved preventive effect on Neural Tubal Defects (NTDs), like spina bifida. However, The biological and clinical potential of FA is reassessing and this represents a hot topic in scientific community, mostly in consideration of the possible medical-legal implications. An overview is mandatory in order to keep in mind FA-related possibl

    Analyses of typical bacterial clusters in humans named enterotypes may facilitate understanding the host differences in the cardiometabolic profile. It stills unknown whether the three previously described enterotypes were present in populations living below the equator. We examined how the identification of enterotypes could be useful to explain the dietary associations with cardiometabolic risk factors in Brazilian subjects. In this cross-sectional study, a convenience sample of 268 adults (54.2% women) reported their dietary habits and had clinical and biological samples collected. In this study, we analyzed biochemical data and metagenomics of fecal microbiota (16SrRNA sequencing, V4 region). Continuous variables were compared using ANOVA, and categorical variables using chi-square test. Vsearch clustered the operational taxonomic units, and Silva Database provided the taxonomic signatures. Spearman coefficient was used to verify the correlation between bacteria abundances within each enterotype. One hundred subjects were classified as omnivore, 102 lacto-ovo-vegetarians, and 66 strict vegetarians. We found the same structure as the three previously described enterotypes: 111 participants were assigned to Bacteroides, 55 to Prevotella, and 102 to Ruminococcaceae enterotype. The Prevotella cluster contained higher amount of strict vegetarians individuals than the other enterotypes (40.0 vs. 20.7 and 20.6, p = 0.04). Subjects in this enterotype had a similar anthropometric profile but a lower mean LDL-c concentration than the Bacteroides enterotype (96 +/- 23 vs. 109 +/- 32 mg/dL, p = 0.04). We observed significant correlations between bacterial abundances and cardiometabolic risk factors, but coefficients differed depending on the enterotype. In Prevotella enterotype, Eubacterium ventriosum (r BMI = -0.33, p = 0.03, and r HDL-c = 0.33, p = 0.04), Akkermansia (r 2h glucose = -0.35, p = 0.02), Roseburia (r BMI = -0.36, p = 0.02 and r waist = -0.36, p = 0.02), and Faecalibacterium (r insulin = -0.35, p = 0.02) abundances were associated to better cardiometabolic profile. The three enterotypes previously described are present in Brazilians, supporting that those bacterial clusters are not population-specific. Diet-independent lower LDL-c levels in subjects from Prevotella than in other enterotypes suggest that a protective bacterial cluster in the former should be driving this association. Enterotypes seem to be useful to understand the impact of daily diet exposure on cardiometabolic risk factors. Prospective studies are needed to confirm their utility for predicting phenotypes in humans.FAPESPUniv Sao Paulo, Sch Publ Hlth, Dept Epidemiol, Sao Paulo, BrazilFundacao Oswaldo Cruz, Rene Rachou Res Ctr, Belo Horizonte, MG, BrazilUniv Fed Sao Paulo, Dept Prevent Med, Sao Paulo, BrazilUniv Sao Paulo, Sch Med, Heart Inst Incor, Lab Genet & Mol Cardiol, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Prevent Med, Sao Paulo, BrazilFAPESP: 2012/12626-9FAPESP: 2012/03880-9Web of Scienc

    The European Marine Observation and Data Network (EMODnet): Visions and roles of the gateway to marine data in Europe

    Get PDF
    Marine data are needed for many purposes: for acquiring a better scientific understanding of the marine environment, but also, increasingly, as marine knowledge for decision making as well as developing products and services supporting economic growth. Data must be of sufficient quality to meet the specific users' needs. It must also be accessible in a timely manner. And yet, despite being critical, this timely access to known-quality data proves challenging. Europe's marine data have traditionally been collected by a myriad of entities with the result that much of our data are scattered throughout unconnected databases and repositories. Even when data are available, they are often not compatible, making the sharing of the information and data aggregation particularly challenging. In this paper, we present how the European Marine Observation and Data network (EMODnet) has developed over the last decade to tackle these issues. Today, EMODnet is comprised of more than 150 organizations which gather marine data, metadata, and data products and make them more easily accessible for a wider range of users. EMODnet currently consists of seven sub-portals: bathymetry, geology, physics, chemistry, biology, seabed habitats, and human activities. In addition, Sea-basin Checkpoints have been established to assess the observation capacity in the North Sea, Mediterranean, Atlantic, Baltic, Artic, and Black Sea. The Checkpoints identify whether the observation infrastructure in Europe meets the needs of users by undertaking a number of challenges. To complement this, a Data Ingestion Service has been set up to tackle the problem of the wealth of marine data that remain unavailable, by reaching out to data holders, explaining the benefits of sharing their data and offering a support service to assist them in releasing their data and making them available through EMODnet. The EMODnet Central Portal (www.emodnet.eu) provides a single point of access to these services, which are free to access and use. The strategic vision of EMODnet in the next decade is also presented, together with key focal areas toward a more user-oriented service, including EMODnet for business, internationalization for global users, and stakeholder engagement to connect the diverse communities across the marine knowledge value chain

    Food Web in an Artificial Basin of Southern Italy: Lake Angitola of Calabria

    The Angitola lake is an artificial basin (created in 1966) located in the southern Italy. The basin is protected by the international Ramsar Convention, “Natura 2000” Network and specific Regional acts. There are few scientific data concerning the lake characteristics, its wildlife and environmental health. In the present study, we examined biodiversity presence and environmental interactions with focus on benthic macro-invertebrates community. We observed an oscillation in water level with a maximum in May and a minimum in December. The visibility ranging from 70 to 40 cm. This study do not focus on quantitative data about mammals, birds, reptiles and amphibians. Fishing sampling showed a high amount of Carassius carassius, a small number of Perca fluviatilis and Squalius cephalus (Lake sampling points); a large number of Gambusia spp., a good presence of Salaria fluviatilis and a few presence of Cobitis bilineata (River sampling points). Spring and summer samplings show the highest number of insects; autumn and winter samplings a higher presence of mollusk, segmented and round worms. Seasonal variation within classes did not result significant in all sampling stations. Taxa numerosity in the lake differed between each class over time (P=0.0024) and time did not show any effect (P=0.98). Interaction of classes over time resulted significant (P=0.03). Similar results were recorded for the river (class difference P<0.0001; time effect P=0.1; interaction of class over time P=0.006). In the lake, a strong negative correlation resulted between Insects and either Mollusks (ρ=-0.9, P<0.0001) or Worms (ρ=-0.99, P<0.0001); a strong positive correlation resulted between Worms and Mollusks (ρ=0.87, P=0.0003). In the river, a strong negative correlation between Insects and either Mollusks (ρ=-0.85, P=0.0005) or Worms (ρ=-0.97, P<0.0001) was confirmed, whereas no correlation existed between Mollusks and Worms. This paper is the first approach about food web of Lake Angitola with the objective of. The biodiversity analysis and the identification of the critical points allow us to identify preliminary relationships, the food web and the main energy input in the Angitola environments. On such premises, it is therefore essential to monitor the chemical, physical and biological trends over years
