Effects of tri-n-butyltin(IV) chloride on neurulation of Ciona intestinalis (Tunicata, Ascidiacea): an ultrastructural study
2005
This paper reports the cytotoxic effects of tri-n-butyltin (IV) chloride, TBTCl, on the neurulation process of the ascidian Ciona intestinalis. Exposure of the embryos at early neurula stage in 10−5 and 10−7M TBT (IV) chloride solutions for 1–2 h provoked the irreversible arrest of their development. Morphological and ultrastructural observations suggested that most probably there are two principal causes determining the neurulation process block. The first is due to the TBT effects of inhibiting the polymerization and/or degradation of microfilaments and microtubules, proteins that constitute the cytoskeleton. The lack of orientation and extension of both microtubules and microfilaments of…
A free plate model can predict guided modes propagating in tubular bone-mimicking phantoms
2014
The goal of this work was to show that a non-absorbing free plate model can predict with a reasonable accuracy guided modes measured in bone-mimicking phantoms that have circular cross-section. Experiments were carried out on uncoated and coated phantoms using a clinical axial transmission setup. Adjustment of the plate model to the experimental data yielded estimates for the waveguide characteristics (thickness, bulk wave velocities). Fair agreement was achieved over a frequency range of 0.4 to 1.6 MHz. A lower accuracy observed for the thinnest bone-mimicking phantoms was caused by limitations in the wave number measurements rather than by the model itself.
Sanzione religiosa, procedimenti giuridici e disincanto in Tucidide. Il dramma di Platea
2016
Il racconto tucidideo sul dramma di Platea, oltre ad essere di eccezionale intensità, è anche e soprattutto una riflessione sottile sui confini incerti e precari tra politica e morale, e sull’ambiguità e i rischi delle parole e del discorso pubblico: fuori dal logos, fuori dalla parola, che è sempre parola pubblica, non c’è politica, e dove non c’è politica ogni confine si dissolve e tutto diviene possibile. In questo terreno, su cui lo storico ateniese ci riporta continuamente, le sanzioni religiose e i procedimenti giudiziari invocati di volta in volta dai diversi protagonisti della narrazione sono di fatto sottoposti ad una riflessione corrosiva che ne smaschera la natura dissimulatrice.…
Recent advances on aptamer-based biosensors to detection of platelet-derived growth factor.
2018
Platelet-derived growth factor (PDGF-BB), a significant serum cytokine, is an important protein biomarker in diagnosis and recognition of cancer, which straightly rolled in proceeding of various cell transformations, including tumor growth and its development. Fibrosis, atherosclerosis are certain appalling diseases, which PDGF-BB is near to them. Generally, the expression amount of PDGF-BB increases in human life-threatening tumors serving as an indicator for tumor angiogenesis. Thus, identification and quantification of PDGF-BB in biomedical fields are particularly important. Affinity chromatography, immunohistochemical methods and enzyme-linked immunosorbent assay (ELISA), conventional m…

La platería en la iglesia de los Santos Juanes de Cullera (siglos XVI-XX)
2021
Este escrito estudia la colección de plata de la iglesia de los Santos Juanes de Cullera (La Ribera Baixa), formada por piezas cuya cronología abarca desde el siglo XVI al XX. Se indica la datación de las obras y sus marcas, asignándolas al obrador correspondiente. Las más importantes fueron labradas en el siglo XVIII, como la Custodia procesional, obra del platero Bernat Quinzà (1752-1803), aunque hay otras, como los relicarios de los titulares, de 1696, que también son destacadas. El conjunto de las piezas es interesante y ha llegado hasta nosotros después de muchos avatares, entre los que está el asalto e incendio de la iglesia el 1 de mayo de 1936. Algunas de estas obras eran ya conocid…
