Ophiuroidea of the Avilés Canyons System (INDEMARES + LIFE Project).
The Avilés Canyons System (ACS) is located in the Cantabrian Sea (Bay of Biscay) and is composed of three canyons. It was declared Site of Community Importance (SCI: C ESZZ12003) within the Natura 2000 Network (Ministry of Agriculture, Food and Environment, 2014) due to their diversity of species and vulnerable habitats (Sánchez et.al., 2014). During the years 2010 - 2012 several campaigns of the INDEMARES LIFE - ACS project were carried out. This study includes the zone that goes from the beginning of the continental slope to the maximum depth sampled in the bathyal zone (depth range between 266 and 2291 m). A total of 7413 specimens which correspond to 48 species, were collected from 50 stations. The most abundant species were Ophiocten affinis (Lütken, 1858) with 4092 specimens and Ophiothamnus affinis Ljungman, 1872 with 1842. The most frequent ones were Ophiactis abyssicola (M. Sars, 1861) and Ophiacantha bidentata (Bruzelius, 1805) present in 48% and 26% of stations respectively. Comparing our species with public databases (OBIS, GBIF) and the bibliography, five potential new records have been found for the Cantabrian Sea, part of the North-Atlantic Marine Subdivision (Lavín et. al., 2012).Universidad de Málaga.

STECF Multiannual management plans SWW and NWW (STECF-15-08)
The STECF was tasked with an analysis of the likely effects of proposed management plans for the Southwestern (Bay of Biscay and Iberia)
and Northwestern (Celtic sea) waters. Quantitative analyses were carried out to compare the likely effect of those management plans and of
the direct application of the CFP on both stocks and fleets involved in these fisheries. Based on the results of simulations of the provisions of
the proposed management plans, STECF concluded that, setting fishing opportunities in line with single-species FMSY ranges will provide
managers with additional flexibility compared to the basic provisions of the 2013 CFP. Such flexibility is likely to help alleviate the problem
of mismatches in quota availability in mixed-species fisheries thereby reducing the risk of early closure of some fisheries due to choke
species. Adopting FMSY ranges will therefore increase the likelihood that desired exploitation rates will be achieved and will reduce the risk
that some fishing fleets will go out of business. STECF considers that it is crucial that managers take note that persistent fishing at the upper
limits of the FMSY ranges across all or most stocks simultaneously negates the flexibility introduced by the FMSY ranges and greatly
increases the risk of overfishing. Such an approach will also increase the risk that the objectives of the CFP will not be achieved. STECF
concludes that single species biomass safeguards for all stocks should be maintained to provide a basic level of protection. STECF notes that
for the fleets affected by the SWW MAP, those providing the highest employment are generally not dependent to a great extent on the
species that will be regulated through the MAP proposals. STECF notes that in the NWW there are some fleets which provide significant
levels of employment and seem to be very dependent on the species that will be regulated through the MAP proposals. Nevertheless, there
are a number of fleets in the NWW area that are not included in the employment analysis because of an absence of appropriate data.
.Regarding the number and scope of MAPs as currently defined, STECF considers that a MAP covering a wider geographic area has
advantages in terms of reducing management overheads and avoiding multiple regulations affecting the sector. A larger MAP area however,
may have disadvantages associated with reducing the emphasis on local management measures and this may discourage the involvement of
stakeholders, although this effect will depend on how the process of regionalization operates within the MAP. To evaluate the question of
whether management of the species that drive the fisheries adequately allows for the management of by-catch species, the EWG carried out
an analysis of correlations between catches of driver species identified in the plan and a variety of by-catch species. The analysis suggested
only limited correlation. In view of this, the STECF notes that it is unlikely that relying on the TAC of the driver species to manage other
species will be effective, in accordance with CFP requirements. STECF however notes that when analysis was performed at the fleet level,
there were more obvious correlations, suggesting some scope to use fleet related management measures for the driver species as a way of
managing some of the bycatch species. STECF therefore concludes that management of exploitation rates of non-driver (or bycatch) species
is unlikely to occur as an automatic consequence of the management of the main (driver) stocks by TAC considered in the MAP.DG MAR
Improving the Cryotolerance of Wine Yeast by Interspecific Hybridization in the Genus Saccharomyces
Fermentations carried out at low temperatures (10–15°C) enhance the production and retention of flavor volatiles, but also increase the chances of slowing or arresting the process. Notwithstanding, as Saccharomyces cerevisiae is the main species responsible for alcoholic fermentation, other species of the genus Saccharomyces, such as cryophilic species Saccharomyces eubayanus, Saccharomyces kudriavzevii and Saccharomyces uvarum, are better adapted to low-temperature fermentations during winemaking. In this work, a Saccharomyces cerevisiae × S. uvarum hybrid was constructed to improve the enological features of a wine S. cerevisiae strain at low temperature. Fermentations of white grape musts were performed, and the phenotypic differences between parental and hybrid strains under different temperature conditions were examined. This work demonstrates that hybridization constitutes an effective approach to obtain yeast strains with desirable physiological features, like low-temperature fermentation capacity, which genetically depend on the expression of numerous genes (polygenic character). As this interspecific hybridization approach is not considered a GMO, the genetically improved strains can be quickly transferred to the wine industry
Prognostic factors of a lower CD4/CD8 ratio in long term viral suppression HIV infected children
CoRISpe (Cohorte Nacional de VIH pediátrica de la RED RIS).[Background] Combination antiretroviral therapy (cART) is associated with marked immune reconstitution. Although a long term viral suppression is achievable, not all children however, attain complete immunological recovery due to persistent immune activation. We use CD4/CD8 ratio like a marker of immune reconstitution.[Methods] Perinatal HIV-infected children who underwent a first-line cART, achieved viral suppression in the first year and maintained it for more than 5 years, with no viral rebound were included. Logistic models were applied to estimate the prognostic factors, clinical characteristics at cART start, of a lower CD4/CD8 ratio at the last visit.[Results] 146 HIV-infected children were included: 77% Caucasian, 45% male and 28% CDC C. Median age at cART initiation was 2.3 years (IQR: 0.5–6.2). 42 (30%) children received mono-dual therapy previously to cART. Time of undetectable viral load was 9.5 years (IQR: 7.8, 12.5). 33% of the children not achieved CD4/CD8 ratio >1. Univariate analysis showed an association between CD4/CD8 1 was not achieved in 33% of the children. Lower CD4 nadir and previous exposure to suboptimal therapy, before initiating cART, are factors showing independently association with a worse immune recovery (CD4/CD8 < 1).Peer reviewe

Black list and Alert list of the Aquatic Invasive Alien Species in the Iberian Peninsula: an action of the LIFE INVASAQUA
Resumen del trabajo presentado en VI Congreso Nacional sobre Especies Exóticas Invasoras y I Congreso Ibérico sobre EEI (EEI 2022) celebrado en Navarra del 20 al 23 de abril de 2022.One of the objectives of LIFE INVASQUA project is to develop tools that will be more efficient the Early Warning and Rapid Response (EWRR) framework for Invasive Alien Species in the Iberian Peninsula. Horizon scanning for high-risk IAS is basic in implementing measures to reduce new invasions, developing Alert lists, and to focus effort in the species already established, for instance making a Black list. We developed a trans national horizon scanning exercise focused on inland waters of Spain and Portugal in order to provide a prioritized lists (Black list and Alert list) of aquatic IAS that may pose a threat to aquatic ecosystems and socio economic sectors in the future. We followed a step approach of existing information about IAS (Plants, Freshwater Invertebrates, Estuarine Invertebrates and Vertebrates; 127 established taxa in Black list; 90 non established taxa in Alert list) combining with an expert scoring of prioritized taxa. IAS established in the Iberian aquatic system consistently highlighted as the worst included vertebrates (e.g. Cyprinus carpio, Gambusia holbrooki, Silurus glanis), freshwater and estuarine invertebrates (e.g. Procambarus clarkii, Dreissena polymorpha, Pacifastacus leniusculus, Ficopomatus enigmaticus, Callinectes sapidus, Corbicula fluminea) and plants (e.g. Eichhornia crassipes, Azolla filiculoides, Ludwigia grandiflora). Amongst taxa not yet established (Alert list), expert pointed to Perna viridis, Hydroides dirampha, Dreissena bugensis, Procambarus fallax f. virginallis, Perccottus glenii with higher risk of invasion, ecological and socioeconomic impacts. Over 20.6% of the taxa in the preliminary black list received no votes (no prioritization) by experts, 17.8% in the innitial alert list. Our horizon scanning approach is inclusive of all-taxa, prioritizes both established and emerging biological threats across trans-national scales, and considers not only the ecological impact, but also potential direct economic consequences as well as the manageability of invasive species.This work received funds from the LIFE Programme (LIFE17 GIE/ES/000515)

CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative
Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research
