Plan de Atención a la diversidad en los centros docentes
2008
Se describen los diferentes documentos de los centros educativos y se explica el plan de atención a la diversidad
Mito y realidad en las diferencias de resultados en bachillerato y en la prueba de acceso a la universidad de los centros públicos y privados en Astu…
2010
En la presente investigación se realizan análisis cuantitativos para establecer las posibles diferencias entre los resultados de todos los centros -públicos y privados-, obtenidos en el bachillerato y en la Prueba de Acceso a la Universidad (PAU) por la totalidad del alumnado que se presentó a las PAU, en Asturias, entre los años 2004 y 2008. Se concluye que, efectivamente, existen diferencias de resultados, diferencias entre asignaturas (departamentos) y entre centros. Se plantean hipótesis de trabajo sobre las diferencias intracentro e intercentro, más allá de la dualidad público-privado.
Hsp 56 mRNA in Paracentrotus lividus embryos binds to a mitochondrial protein
2007
We previously demonstrated that Paracentrotus lividus Hsp56 mitochondrial chaperonin is constitutively expressed during development, that it has a specific territorial distribution, both in normal and heat-shocked embryos, and that its amount increases after heat shock [Roccheri MC, Patti M, Agnello M, Gianguzza F, Carra E, Rinaldi AM. Localization of mitochondrial Hsp56 chaperonin during sea urchin development. Biochem Biophys Res Commun 2001;287:1093-98] and cadmium treatment [Roccheri MC, Agnello M, Boneventura R, Matranga V. Cadmium induces the expression of specific stress proteins in sea urchin embryos. Biochem Biophys Res Commun 2004;321:80-7]. In this study, we looked at Hsp56 mRNA …
Embryotoxicity studies of tri-n-butyltin(IV) complexes of 5-[(E)-2-(aryl)-1-diazenyl]-2-hydroxybenzoic acid and 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1…
2005
The toxicity studies of free 5-[(E)-2-(aryl)-1-diazenyll-2-hydroxybenzoic acid and 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyllbenzoic acid and their tri-n-butyltin(IV) complexes were evaluated by using sea urchin early developmental stages as recommended model organisms for toxicity tests. The novel complexes, as the parent tri-n-butyltin(IV) chloride (TBTCl), caused mitosis block and induced high embryonic mortality in sea urchin. Copyright (c) 2005 John Wiley & Sons, Ltd.
Identification of Type I and IX Collagens in the Ascidian Ciona intestinalis
2001
Immunohistochemical methods showed that a type I collagen is a component of the tunic of Ciona intestinalis, involved in the encapsulation process. Since the fibril-forming collagen types are characterized by triple helical domain with a highly preserved Gly-Xaa-Yaa repeated sequence, a probe coding the fibril-forming type I collagen of the echinoderm Paracentrotus lividus was used to identify ascidian cDNA clones. Northern blot hybridization established that P. lividus probe cross-hybridizes with a 6 Kb C. intestinalis mRNA isolated from the pharynx. Using the echinodermal type I collagen cDNA as a probe several positive clones were identified. Analysis of sequence and the deduced amino ac…
Fragments of β-thymosin from the sea urchinParacentrotus lividusas potential antimicrobial peptides against staphylococcal biofilms
2012
The immune mediators in echinoderms can be a potential source of novel antimicrobial peptides (AMPs) applied toward controlling pathogenic staphylococcal biofilms that are intrinsically resistant to conventional antibiotics. The peptide fraction <5 kDa from the cytosol of coelomocytes of the sea urchin Paracentrotus lividus (5-CC) was tested against a group of Gram-positive and Gram-negative pathogen reference strains. The 5-CC of P. lividus was active against all planktonic-tested strains but also showed antibiofilm properties against staphylococcal strains. Additionally, we demonstrated the presence of three small peptides in the 5-CC belonging to segment 9-41 of a P. lividusβ-thymosin. T…
Properties of sea urchin coelomocyte agglutinins
1996
We examined some biological activities of a 200-kDa glycoprotein, referred to as Paracentrotus lividus vitellogenin, contained both in the coelomic fluid and in a subpopulation of coelomocytes called «colourless spherula cells». Cell-free coelomic fluid, coelomocyte lysate and supernatant obtained after coelomocyte washings were assayed for hemagglutinating activity. All samples agglutinated rabbit erythrocytes in a calcium-dependent way. The comparison between the electrophoretic patterns of erythrocyte lysates, before and after incubation with the coelomic fluid, revealed that a 200-kDa band was obtained from membranes of agglutinated erythrocytes. In addition, polyclonal antibodies again…
rac-1,1,1,6,6,6-Hexachlorohex-3-yne-2,5-diol hemihydrate
2017
The asymmetric unit of the title compound, C6H4Cl6O2·0.5H2O, contains one molecule of 1,1,1,6,6,6-hexachlorohex-3-yne-2,5-diol and half a water molecule located on a twofold rotation axis. In the crystal, pairs of hexachlorohexynediol molecules form centrosymmetric dimers connectedviapairwise O—H...O hydrogen bonds. These dimers are connected by water molecules, resulting in layers parallel to theabplane.
