Plant regeneration from isolated cells ofLavandula latifolia medicus
1988
Single cells were obtained from hypocotyl-derived callus ofLavandula latifolia Medicus. Cells were plated in Murashige and Skoog medium supplemented with indoleacetic acid (IAA), benzyladenine (BA), and several IAA-BA combinations. Cell division required the simultaneous presence of IAA and BA in the culture medium, but callus formation was only achieved with 0.1 or 1 mg/liter IAA and 2 mg/liter BA. To induce organogenesis, calli were transferred to various regeneration media. Shoot-bud differentiation efficiency depended on the composition of both the callus induction and the shoot regeneration media, best results being obtained when calli grown in 1 mg/liter IAA and 2 mg/liter BA were sub…
Nanoparticle Assembly of Surface-Modified Proteins
2016
Nature's biomaterials such as peptides and proteins represent a valuable source of highly defined macromolecules. Herein we developed a nanoparticle drug delivery system based on the assembly of surface-modified proteins that can be transferred into organic solvents and represent the structural material of the carrier system. The particles are prepared by an oil-in-water nanoemulsion technique without the need of additional denaturation or cross-linking steps for stabilization. We achieve the necessary lipophilic solubility switch of the protein material by high surface PEGylation under conservation of the native three-dimensional protein structure. This study focuses on lysozyme as model e…
El arte integrado en la batalla. Estudio tecnológico previo a la restauración de cinco armaduras japonesas del Museo del Ejército de Toled
2011
A lo largo del siglo XVIII la moda Chinoiserie se difundió entre las cortes europeas. Basada en modelos chinos y japoneses, la veremos reflejada tanto en la pintura como en la arquitectura, las artes decorativas o el arte textil. Durante este periodo se importaron numerosos objetos de Extremo Oriente con destino a los palacios y casas señoriales, factor determinante en el auge del coleccionismo de piezas de arte exótico, como las lacas japonesas y la porcelana china. Un caso excepcional es el constituido por las armaduras samuráis, verdaderas obras de arte elaboradas en materiales muy diversos y dotadas de una complejidad notable. El objetivo de este artículo es mostrar los estudios previos…
La Casina cinese alla Favorita di Palermo: un'ipotesi di lettura.
2016
L'articolo verte su un'ipotesi interpretativa della componente decorativa della Casina cinese alla Favorita di Palermo basata sulla componente "alla cinese" e su una sua densa natura confuciana. The paper offers a hypothesis of interpretation of the decorative patterns of the Casina cinese at the Favorita Park in Palermo which is based on the component "in Chinese style" that is characterized by a strong Confucian element.
Existence of metastable intermediate lysozyme conformation highlights the role of alcohols in altering protein stability.
2011
Alcohols have a manifold effect on the conformational and thermodynamic stability of native proteins. Here, we study the effect of moderate concentrations of trifluoroethanol (TFE) on the thermal stability of hen egg-white lysozyme (HEWL), by far-UV circular dichroism and by steady-state and time-resolved photoluminescence of intrinsic tryptophans. Our results highlight that TFE affects lysozyme stability by preferential solvation of the protein molecule. Furthermore, we discovered the existence at 20% TFE of an equilibrium partially folded state of lysozyme, intermediate between the native and the unfolded state. A three-state model is therefore used to interpolate the thermal denaturation…
Somatic embryogenesis and plant regeneration from pistil thin cell layers of Citrus
1999
Callus induction, somatic embryogenesis and plant regeneration were obtained in six different citrus species [Citrus deliciosa Ten. (cv 'Avana'), C.limon (L.) Burm. (cv 'Berna'), C.madurensis Lour. (cv 'CNR P9'), C.medica L. (cv 'Cedro di Trabia'), C.tardiva Hort. ex Tan. (cv 'CNR P6'), C.sinensis (L.) Osb. (cv 'Ugdulena 7')] from cultures of pistil transverse thin cell layer explants [(t)TCL]. Explants were cultured on three different media: the nutrients and vitamins of Murashige and Skoog medium alone (MS) or MS supplemented with either 500 mg l(-1) malt extract (MS I) or 500 mg l(-1) malt extract and 13.3 mu M 6-benzylaminopurine (MS II). Sucrose (146 mM) was used as the carbon source. …
Entre Domat et Beccaria: Muratori et la codification de la jurisprudence
2014
A classical text from the ltalian legal literature of the first half of the eighteenth century, but little known outside Italy, the treaty De’ difetti della giurisprudenza (On the Defects of Jurisprudence, 1742) is the work of historian and philosopher Lodovico Antonio Muratori who was from Modena. Since he was opposed to the alterations which had changed the common law inspired by Justinian principles, his treaty embraces the passion of the century for a new legal rationality. Partly dependent on the design of unification of the Roman law developed by Jean Domat, Muratori’s critical thinking feeds in its turn Baccaria’s draft to streamline the right to punish. Thus, between the time of con…

A Systematic Nomenclature for the Insect Brain
2014
SummaryDespite the importance of the insect nervous system for functional and developmental neuroscience, descriptions of insect brains have suffered from a lack of uniform nomenclature. Ambiguous definitions of brain regions and fiber bundles have contributed to the variation of names used to describe the same structure. The lack of clearly determined neuropil boundaries has made it difficult to document precise locations of neuronal projections for connectomics study. To address such issues, a consortium of neurobiologists studying arthropod brains, the Insect Brain Name Working Group, has established the present hierarchical nomenclature system, using the brain of Drosophila melanogaster…
Analisi delle murature storiche di Caltabellotta
2020
L’architettura storica di pregio, ed ancor più l’edilizia di base dei piccoli centri montani - caratterizzati da un isolamento che spesso rendeva difficoltoso non solo lo spostamento delle maestranze ma anche l’approvvigionamento di materie prime per la costruzione – sono generalmente connotate da specificità derivanti dalla disponibilità in situ di risorse e da consuetudini non codificate che trovano raramente riscontro puntuale nelle “regole dell’arte” riportate nella manualistica e nella trattatistica “ufficiale”. Rappresentativo in tal senso è il caso di Caltabellotta; l’antico borgo sulla valle del Platani – che domina tre colli, il Monte San Pellegrino, il Monte Castello e il Monte Go…
