Tacitus on Titus? Visit to the Temple of Venus at Paphos

2020

This article deals with Titus? visit to the temple of Venus at Paphos in the second book of Tacitus? Historiae. I argue that apart from its other literary intentions already mentioned by scholars, this digression implicitly connects Titus not only with Aeneas but also with Julius Caesar. Titus? affair with Berenice that recalls Caesar?s affair with Cleopatra, Tacitus? allusions to Lucan?s De Bello Civili where Caesar?s visit to the tomb of Alexander the Great is described, the ?????Motiv and fortuna?s favour that characterise both Roman generals, all contribute to connect Titus with Caesar and allow the reader to view a parallel between the Flavian and the Julio-Claudian dynasty.

Initial steps of wall protoplast regeneration in Candida albicans

1997

Summary Cell wall regeneration of individual Candida albicans yeast and mycelial protoplasts was studied with confocal and electron microscopy using polyclonal antibodies and leetins. Quantitative measurements of the fluorescence emitted by individual protoplasts during the process of regeneration indicate that chitin is the first polymer to be laid down, whereas β(1,3)- and β(1,6)glucan are incorporated at a later stage. Mannoproteins were found on the surface of fresh protoplasts and those newly synthesized were then deposited with time. During the first steps of wall regeneration, the proteins that interacted covalently with chitin or glucan were different, but the same species were foun…

Edición de El conde Lucanor (Sevilla: Hernando Díaz, 1575), al cuidado de Gonzalo Argote de Molina (2ª parte)

2016

Después de una breve introducción sobre los principales cambios en la macroestructura y en el texto, se presenta la segunda parte de la editio princeps del Conde Lucanor (Sevilla: Hernando Díaz, 1575), concretamente los cuentos de don Juan Manuel y los paratextos finales (un tratado poético sobre la poesía castellana y un glosario).

Dichos de sabios y poesía de cancionero: la recepción de los Dichos de Sulpicio y los proverbios del Conde Lucanor en Ruy Páez de Ribera y Francisco …

2020

En este artículo se argumenta que los Dichos de Sulpicio están citados en el poema de Ruy Páez de Ribera «Gosté el axarope del grant cicotrí» (Baena 291) y un proverbio de El conde Lucanor (III, 26) en la poesía de Francisco Imperial «En un fermoso vergel» (Baena 242). Si se aceptan dichas identificaciones, la primera proporciona una fecha ante quem de hacia 1425 para los Dichos de Sulpicio y la segunda contribuye al número reducido de citas textuales de la obra de don Juan Manuel. La presencia de los dos textos sapienciales indica un foco de interés por la literatura de proverbios en la Sevilla de la primera mitad del siglo XV.

Regeneration of the cell wall in protoplasts of Candida albicans. A cytochemical study using wheat germ agglutinin and concanavalin A.

1988

To assess the dynamics of synthesis of the wall by regenerating Candida albicans protoplasts deposition of chitin and mannoproteins were investigated ultrastructurally using wheat germ agglutinin conjugated with either horseradish peroxidase or colloidal gold, and Concanavalin A coupled to ferritin respectively. Freshly prepared protoplasts lacked wheat germ agglutinin receptor sites but after 1-2 h of regeneration, they were detected. After 4-5 h of regeneration, the cell wall showed a discrete structure which was only labelled with wheat germ agglutinin in thin sections. At this stage of regeneration the outermost layer of the wall was labelled with clusters of Concanavalin A-ferritin par…

Xyloglucan-based hydrogels: A biomaterials chemistry contribution towards advanced wound healing

The last two decades have witnessed the introduction of several new wound dressings, with many of them being hydrogels for the advantages that these materials can offer in the application. However, despite the advancements and the wide range of dressings available, wound management is still an extremely challenging task due to its subjectivity, complexity and scarce knowledge of the wound healing process itself, and patient variability. For this reason, an interdisciplinary approach to wound care that can help reducing the incidence and prevalence of wounds is needed. One important goal would be to develop “smart” wound dressings that are easy to apply, wear and be removed, that are able to…

Immunomodulatory effects of dietary β-1,3-glucan from Euglena gracilis in rainbow trout (Oncorhynchus mykiss) immersion vaccinated against Yersinia r…

2012

Abstract Potential immunostimulatory effects of orally administered β-glucan were investigated in combination with immersion vaccination against enteric redmouth disease caused by Yersinia ruckeri in rainbow trout (Oncorhynchus mykiss). A linear, unbranched and pure (purity ≥98%) β-1,3-glucan (syn. paramylon) from the alga Euglena gracilis was applied at an inclusion level of 1% β-glucan in feed administered at a rate of 1% biomass day−1 for 84 consecutive days. Fish were vaccinated after two weeks of experimental feeding and bath challenged with live Y. ruckeri six weeks post-vaccination. Blood and head kidney were sampled at day 0, 13 (1 day pre-vaccination), 15, 55, 59 (day 3 post-challe…

«… Il tamburo di Lucano». Leopardi lettore della Pharsalia

2022

Dopo aver rapidamente ricostruito la lettura di Lucano compiuta tra ’700 e ’800, il contributo focalizza la sua attenzione sulla presenza della Pharsalia nella produzione leopardiana, cercando in particolare di verificare a partire da quale momento Leopardi mostri una conoscenza diretta del poema epico e soffermandosi su giudizi critici espressi a più riprese soprattutto nello Zibaldone. After having rapidly reconstructed the reading of Lucan between the 18th and 19th centuries, the contribution focuses its attention on the presence of Pharsalia in Leopardi’s production. The article tries to reconstruct from which moment Leopardi shows a direct knowledge of the epic poem and focuses on crit…

Are the xyloglucans new elicitors of plant immunity ?

2017

Damaged-Associated Molecular Patterns (DAMPs) are endogenous molecules released from the plant cell wall after wounding by pathogens. DAMPs are recognized by Pattern- Recognition Receptors (PRRs) that play a key role in plant immunity by mediating defense responses. The plant cell wall-derived oligogalacturonides (OG) are well characterized DAMPs that elicit plant immune responses such as MAPK activation, [Ca2+]cyt variations, H2O2 production, defense-related gene expression and enhanced resistance against Botrytis cinerea. Our study focused on a new polysaccharide component of the plant cell wall called xyloglucans (Xh) and compared the immune events triggered by OG and Xh in Arabidopsis t…

Comparative analysis of PR gene expression in tomato inoculated with virulent Fusarium oxysporum f. sp. lycopersici and the biocontrol strain F. oxys…

2008

Non-pathogenic strains of Fusarium oxysporum have the capacity to protect plants against wilt induced by pathogenic strains of F. oxysporum. Among the mechanisms involved in this protection, induced systemic resistance has been demonstrated by using a split-root method. The aim of this study was to follow the accumulation kinetics of transcripts encoding 5 PR proteins in roots and leaves of tomato inoculated with a pathogenic or a protective strain in comparison to non-inoculated control. Moreover quantification of transcripts was assessed by real-time RT-PCR in cell cultures inoculated with the pathogenic or the protective strain. Results showed a lower expression of PR encoding genes in t…
