A taxonomic revision helps to clarify differences between the Atlantic invasive
2017
Abstract Ptilohyale explorator (formerly Parhyale explorator), described by Arresti (1989), can be considered to be a synonym of west-Atlantic Ptilohyale littoralis (Stimpson, 1853), based on morphological observations of paratypes and specimens recently collected in the type locality of Ptilohyale explorator. The first collections of Ptilohyale littoralis, from the eastern Atlantic were from the port of Rotterdam (The Netherlands) in 2009 and later in Wimereux, Opal Coast (France) in 2014; however, the synonymy of Ptilohyale explorator with Ptilohyale littoralis backdates to the first European record of Ptilohyale littoralis in 1985 at La Vigne, Bay of Arcachon (France). This indicates tha…
Cross-resistance and mechanism of resistance to Cry1Ab toxin from Bacillus thuringiensis in a field-derived strain of European corn borer, Ostrinia n…
2011
The cross-resistance spectrum and biochemical mechanism of resistance to the Bacillus thuringiensis Cry1Ab toxin was studied in a field-derived strain of Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae) that was further selected in the laboratory for high levels (>1000-fold) of resistance to Cry1Ab. The resistant strain exhibited high levels of cross-resistance to Cry1Ac and Cry1Aa but only low levels of cross-resistance (<4-fold) to Cry1F. In addition, there was no significant difference between the levels of resistance to full-length and trypsin-activated Cry1Ab protein. No differences in activity of luminal gut proteases or altered proteolytic processing of the toxin were observed in…
Insecticidal Genetically Modified Crops and Insect Resistance Management (IRM)
2008
Economically important crops, such as maize and cotton, have been transformed with genes encoding insecticidal proteins from Bacillus thuringiensis (Bt) to confer them protection against the most important insect pests. Of the 114 million hectares globally planted with GM crops in 2007, over one third are insect-resistant Bt crops, and the area keeps increasing every year. The potential for insects to evolve resistance to GM insecticidal plants is considered to be one of the main threats to this technology, since resistance to Bt sprayable products has been demonstrated. Insect resistance management plans for this new class of pesticides are encouraged and became mandatory in the USA. Of th…
Analyses of Cry1Ab binding in resistant and susceptible strains of the European corn borer, Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae).
2006
ABSTRACT Cry1Ab toxin binding analysis was performed to determine whether resistance in laboratory-selected Ostrinia nubilalis strains is associated with target site alteration. Brush border membrane vesicles were prepared using dissected midguts from late instars of susceptible and resistant strains (Europe-R and RSTT) of O. nubilalis . Immunoblot analysis indicated that three different proteins bound to Cry1Ab toxin and were recognized by an anticadherin serum. In a comparison of resistant and susceptible strains, reduced Cry1Ab binding was apparent for all three bands corresponding to cadherin-like proteins in the Europe-R strain, while reduced binding was apparent in only one band for t…

Evaluating the extent of patient-centred care in a selection of ESC guidelines
2019
AIMS: Patient-centred care (PCC) is the cornerstone for healthcare professionals to promote high quality care for patients with cardiovascular conditions. It is defined as 'Providing care that is respectful of, and responsive to, individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions'. PCC can improve patient outcomes and allow patients and healthcare professionals to manage care collaboratively using best available evidence. However, there is no clear understanding how extensively guidelines incorporate PCC recommendations. The aim of the study was to evaluate the incorporation of PCC into a selection of guidelines published by the E…
Probabilistic Corner Detection for Facial Feature Extraction
2009
After more than 35 years of resarch, face processing is considered nowadays as one of the most important application of image analysis. It can be considered as a collection of problems (i.e., face detection, normalization, recognition and so on) each of which can be treated separately. Some face detection and face recognition techniques have reached a certain level of maturity, however facial feature extraction still represents the bottleneck of the entire process. In this paper we present a novel facial feature extraction approach that could be used for normalizing Viola-Jones detected faces and let them be recognized by an appearance-based face recognition method. For each observed featur…
SARS-CoV-2: Impact on, Risk Assessment and Countermeasures in German Eye Banks.
2020
Introduction Since the beginning of the COVID-19 pandemic there has been some debate regarding the risk of transmission through tissue transplantation and tissue banking processes. Aim of the study To analyze the changes that SARS-CoV-2 has caused regarding the harvesting of corneal donor tissue and eye bank activities in Germany. Methods A questionnaire was provided to 26 eye banks in Germany, consisting of questions about adaptations made in the screening of potential donors and the harvesting of corneal tissue following the pandemic spread of SARS-CoV-2. Results Eighteen eye banks actively reduced recruitment of donors and two banks ceased all activity. Additional diagnostic screening wa…
Fernand de Montessus de Ballore, à la naissance de la sismologie moderne
2012
Fernand de Montessus de Ballore (1851-1923) est considéré comme un des précurseurs de la sismologie moderne. On lui doit une importante production scientifique dans ce domaine : il a notamment établi, par des relevés rigoureux et nombreux, que les tremblements de terre étaient en relation avec la géologie et non avec les phases de la lune ou les volcans souterrains comme on le supposait au début du XXe siècle. Officier de l'armée française, alors en garnison à Nîmes, il écrit en 1886 au scientifique genevois Louis Soret (1827-1890), qui fait partie de la commission suisse chargée d'étudier les séismes dans ce pays. C'est l'analyse de cette lettre à Soret qui fait l'objet de notre article.
