mp23, a Theileria parva transmembrane protein with homology to the protein disulfide isomerase family
2002
The protozoan parasite Theileria parva (Apicomplexa) causes the bovine disease East Coast Fever in endemic areas in Subsaharan Africa. The intralymphocytic schizont stage is largely responsible for the pathogenicity and induces a transformed phenotype in host cells [1]. Current evidence supports a model in which the schizont perturbs the immune response by inducing production of cytokines and stimulating the growth of parasitized cells [2]. We were interested to identify parasite proteins involved in parasite/host interaction and have described earlier a screening procedure for identification of schizont stage-exported proteins based on cell-free expression of cDNA and testing for transloca…
A novel cell wall protein specific to the mycelial form of Yarrowia lipolytica.
1996
A cDNA clone specifying a cell wall protein was isolated from a Yarrowia lipolytica cDNA library. The cDNA library was constructed in the expression vector lambda gt 11, with the RNA isolated from actively growing mycelial cells. The deduced amino acid sequence shows that the encoded protein contains an N-terminal hydrophobic signal peptide. We have designated this protein YWP1 for Yarrowia lipolytica cell Wall Protein. Northern hybridization identified YWP1 transcript only when Y. lipolytica was growing in the mycelial form. The encoded protein seems to be covalently bound to the glucan cell wall since it is not released from the cell walls by sodium dodecyl sulphate extraction, but it is …
Characterization of two new cuticular genes specifically expressed during the post-ecdysial molting period in Tenebrio molitor
1998
Abstract In a previous study, we have isolated a cDNA, TM-ACP17 , coding for a post-ecdysial adult protein of Tenebrio molitor . After screening of a genomic library with TM-ACP17 , we report isolation and sequencing of TM-ACP17 gene and a new gene, TM-LPCP29 , coding for a larval–pupal protein. These two genes exhibit a common sequence of 15 nucleotides and a characteristic of most cuticular protein genes so far described: an intron interrupting the signal peptide. The deduced aa sequence of TM-LPCP29 exhibits a high percentage of Ala (26.5%) and Val (17.5%) and is highly hydrophobic. In the N-terminal part, the motif VAAPV is repeated ten times. Numerous histidine residues are present in …
Design of Multiresolution Operators Using Statistical Learning Tools: Application to Compression of Signals
2012
Using multiresolution based on Harten's framework [J. Appl. Numer. Math., 12 (1993), pp. 153---192.] we introduce an alternative to construct a prediction operator using Learning statistical theory. This integrates two ideas: generalized wavelets and learning methods, and opens several possibilities in the compressed signal context. We obtain theoretical results which prove that this type of schemes (LMR schemes) are equal to or better than the classical schemes. Finally, we compare traditional methods with the algorithm that we present in this paper.
Electrochemical analysis of the first Polish coins using voltammetry of immobilized particles
2017
[EN] A series of 20 denarii from Boleslaus the Brave (992-1025) and Mieszko II Lambert (1025-1034), corresponding to the beginning of the Polish state were studied using the voltammetry of immobilized particles (VIMP) methodology. VIMP experiments, applied to nanosamples of the corrosion layers of the coins in contact with aqueous acetate buffer, provided well-defined responses mainly corresponding to the corrosion products of copper and lead. Such voltammetric responses, combined with X-ray fluorescence (XRF) spectroscopy experiments performed on the same set of coins, and complemented by focusing ion beam-field emission scanning electron microscope (FIB-FESEM) on silver coins from the 19t…
Los archivos de distrito en Portugal: memoria administrativa, histórica y social
2018
Se presenta un análisis de la evolución histórico-jurídi ca de los Archivos de Distrito (AD) portugueses, como instituciones que asumen la salvaguarda del patrimo nio público-administrativo del país. Para ello se revisa la bibliografía más relevante sobre el tema, así como la documentación histórica, legal y política, describien do su historia desde sus orígenes y los nuevos caminos que se van trazando, en relación con el aumento de la accesibilidad a la documentación que gestionan y a las nuevas estrategias de difusión de la información entre la ciudadanía. Todo ello en el marco de las distintas ini ciativas de modernización administrativa y las nuevas tecnologías disponibles.

proTRAC - a software for probabilistic piRNA cluster detection, visualization and analysis
2012
Abstract Background Throughout the metazoan lineage, typically gonadal expressed Piwi proteins and their guiding piRNAs (~26-32nt in length) form a protective mechanism of RNA interference directed against the propagation of transposable elements (TEs). Most piRNAs are generated from genomic piRNA clusters. Annotation of experimentally obtained piRNAs from small RNA/cDNA-libraries and detection of genomic piRNA clusters are crucial for a thorough understanding of the still enigmatic piRNA pathway, especially in an evolutionary context. Currently, detection of piRNA clusters relies on bioinformatics rather than detection and sequencing of primary piRNA cluster transcripts and the stringency …
Les Juges et l’Assassin (de l’École) : les méfaits illusoires du progressisme
2021
Dans le droit fil des ouvrages qui, chaque rentrée scolaire et littéraire, déplorent avec une belle régularité le déclin continu du système éducatif, un récent pamphlet s’est donné pour mission de dénoncer les assassins de l’école au nombre desquels se trouve Alain Viala. Le procédé, qui n’est pas nouveau, ne doit pas dissimuler au fil des ans les subtiles évolutions de cette tradition littéraire. Évolution tout d’abord du profil des contempteurs du progressisme éducatif qui semble s’adapter ...
