BEEHOPE: um projeto de conservação das subespécies nativas de abelha da Europa Ocidental (linhagem M) à escala Europeia

O projeto BEEHOPE, com o título original “Honeybee conservation centres in western Europe - an innovative strategy using sustainable beekeeping to reduce honeybee decline”, foi um dos 10 aprovados na área da biodiversidade do 5º concurso transnacional (2013-2014) BiodivErsA/FACCE-JPI (http://www.biodiversa.org/766), subordinado ao tema “Promover sinergias e reduzir o compromisso entre o abastecimento de alimentos, biodiversidade e serviços dos ecossistemas”. A diversidade nativa das populações de abelha melífera (Apis mellifera) da linhagem da Europa ocidental (M) tem vindo a ser crescentemente ameaçada pela introdução massiva de colónias da linhagem da Europa oriental (C, onde se incluem as subespécies A. m. ligustica, A. m. carnica, A. m. macedónica etc.), e também por outros fatores bióticos (Varroa e vírus associados, Nosema etc.) e abióticos (pesticidas, perda e fragmentação de habitat, alterações climáticas etc.). É neste contexto que surge o projeto BEEHOPE, o qual tem por objetivo último contribuir para a conservação da diversidade genética das populações de abelha melífera da linhagem M.info:eu-repo/semantics/publishedVersio

TStore: A Trace-Base Management System using Finite-State Transducer Approach for Trace Transformation

International audienceThis paper presents TStore, a Trace-Base Management System (TBMS) handling storage, transformation and exploitation of traces collected by external applications. As the experiments reported in this paper demonstrate, TStore brings a solution to performances and storage issues usually encountered by TBMS. To exploit traces, transformations are used. TStore provides predefined transformation functions as well as a customized transformation based on Finite State Transducers (FST), which are also presented in this paper

TStore: A Web-Based System for Managing, Transforming and Reusing Traces

International audienceThis paper presents TStore, a Trace-Based Management System that handles the storage, transformation and reusing of Traces. Traces have been of-ten stored without explicit structure. TStore is a web tool that allows anyone to store and reuse traces with their models from various applications. The trans-formation of Traces helps to move from a first simple interpretation (almost raw data coming from sensors) to the actionable knowledge level of abstraction. TStore provides predefined transformation functions as well as a customized transformation based on Finite State Transducers. Our experiments demonstrat-ed the efficiency of TStore to handle the storage requests. They show that batch operations are more efficient than sequentially adding traces to the system

Honeybee preservation centers in Western Europe: an innovative strategy using sustainable beekeeping to reduce honeybee decline

Apis mellifera is subdivided into at least 26 physiologically, behaviourally and morphologically distinct subspecies. As an agronomical species of interest, the natural distribution of honeybee subspecies has been disturbed for many decades by beekeeping activities, particularly because of international trade of honeybees. These movements were particularly amplified this last decade due to livestock rebuilding to counter the effects of colony losses. An interesting assumption is that current honeybee declines observed in European apiaries can be caused by commercial and European trades of honeybees by (i) the introduction (for their apicultural traits) of non- adapted and artificially maintained colonies, and (ii) the spread of allochtone and invasive pathogens carried by allochtones bees. Genetic surveys have demonstrated that some populations of honeybee subspecies are adapted to local climate and flora. Those populations thus constitute particularly interesting populations to study and preserve in a context of sustainable beekeeping. BEEHOPE, our BioDIVERSA ERANET funded project, is to set up, according to a North/South gradient, genetic conservatories of original naturally distributed honeybee populations. These honeybee conservation areas will have as missions: (i) to characterize the genetic and eco-ethologic diversity of honeybees from the West-Mediterranean lineage, (ii) to preserve the genetic diversity of those populations, (iii) to constitute a reserve of diversity usable by the honeybee industry and by beekeepers, (iv) to study the impact of the domesticated honeybee in the maintenance of local floristic diversity, and (v) to be able to use the honeybee as a bio-collector and as a biological indicator of environmental quality

BEEHOPE: um projeto de conservação das subespécies nativas de abelha da Europa Ocidental (linhagem M) à escala Europeia

A abelha melífera, Apis mellifera L., é um organismo extremamente importante em termos económicos, agrícolas e ambientais pois presta um serviço ecossistémico essencial, como é o caso da polinização. Porém, um número crescente de factores tem ameaçado este organismo chave, incluindo a introdução de novos parasitas e predadores, a perda e fragmentação de habitat, a má nutrição, as alterações climáticas, os agroquímicos e a perda de diversidade genética. Em adição ao declínio mundial das populações de abelha melífera, a distribuição das subespécies nativas da Europa tem sido crescentemente ameaçada pelo comércio de abelhas de subespécies exóticas e até de linhas genéticas artificiais (e.g. buckfast). O comércio de abelhas tem conduzido não só ao estabelecimento de colónias inadaptadas e mantidas artificialmente, como também à introdução dos seus parasitas, com as consequências nefastas que daí advém. Vários estudos genéticos conduzidos na Europa têm revelado que muitas populações nativas de abelha melífera estão adaptadas ao clima e flora local. Essas populações são interessantes para serem estudadas e preservadas num contexto de uma apicultura sustentável. O projeto BEEHOPE, financiado pela BiodivERsA ERA-Net, pretende estabelecer, ao longo de um gradiente Norte/Sul, diversos apiários para a conservação do fundo genético das populações nativas de abelha melífera da Europa Ocidental. Estes apiários de conservação terão como missão: (i) servir de base à caracterização da diversidade genética e eco-etológica das abelhas da linhagem da Europa Ocidental (M), (ii) preservar a diversidade genética dessas populações, (iii) constituir uma reserva de diversidade para a indústria apícola e apicultores, (iv) servir para estudar o impacto da abelha domesticada na manutenção da diversidade florística local, e (v) servir de base à utilização da abelha como um bio-coletor e como bio-indicador da qualidade ambiental. Nesta comunicação o projeto BEEHOPE será apresentado, dando-se especial enfase à componente que está a ser desenvolvida em Portugal.info:eu-repo/semantics/publishedVersio

Comparison of Immediate With Delayed Stenting Using the Minimalist Immediate Mechanical Intervention Approach in Acute ST-Segment-Elevation Myocardial Infarction: The MIMI Study.

International audienceDelayed stent implantation after restoration of normal epicardial flow by a minimalist immediate mechanical intervention aims to decrease the rate of distal embolization and impaired myocardial reperfusion after percutaneous coronary intervention. We sought to confirm whether a delayed stenting (DS) approach (24-48 hours) improves myocardial reperfusion, versus immediate stenting, in patients with acute ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention.In the prospective, randomized, open-label minimalist immediate mechanical intervention (MIMI) trial, patients (n=140) with ST-segment-elevation myocardial infarction ≤12 hours were randomized to immediate stenting (n=73) or DS (n=67) after Thrombolysis In Myocardial Infarction 3 flow restoration by thrombus aspiration. Patients in the DS group underwent a second coronary arteriography for stent implantation a median of 36 hours (interquartile range 29-46) after randomization. The primary end point was microvascular obstruction (% left ventricular mass) on cardiac magnetic resonance imaging performed 5 days (interquartile range 4-6) after the first procedure. There was a nonsignificant trend toward lower microvascular obstruction in the immediate stenting group compared with DS group (1.88% versus 3.96%; P=0.051), which became significant after adjustment for the area at risk (P=0.049). Median infarct weight, left ventricular ejection fraction, and infarct size did not differ between groups. No difference in 6-month outcomes was apparent for the rate of major cardiovascular and cerebral events.The present findings do not support a strategy of DS versus immediate stenting in patients with ST-segment-elevation infarction undergoing primary percutaneous coronary intervention and even suggested a deleterious effect of DS on microvascular obstruction size.URL: http://www.clinicaltrials.gov.
