Priming for JA-dependent defenses using hexanoic acid is an effective mechanism to protect Arabidopsis against B. cinerea

2011

Abstract Soil drench treatments with hexanoic acid can effectively protect Arabidopsis plants against Botrytis cinerea through a mechanism based on a stronger and faster accumulation of JA-dependent defenses. Plants impaired in ethylene, salicylic acid, abscisic acid or glutathion pathways showed intact protection by hexanoic acid upon B. cinerea infection. Accordingly, no significant changes in the SA marker gene PR-1 in either the SA or ABA hormone balance were observed in the infected and treated plants. In contrast, the JA signaling pathway showed dramatic changes after hexanoic acid treatment, mainly when the pathogen was present. The impaired JA mutants, jin1-2 and jar1 , were unable …

Succinate-bonded pullulan: An efficient and reusable super-sorbent for cadmium-uptake from spiked high-hardness groundwater.

2015

Abstract Chemically modified pullulan was evaluated for its sorption efficiency and selectivity to remove cadmium (Cd) from spiked high-hardness groundwater (GW). Pullulan esterified with succinic anhydride using dimethylaminopyridine showed a fairly high degree of substitution value as confirmed by 1 H NMR spectroscopy. Pullulan succinate (Pull-Suc) was converted into the sodium salt (Pull-Suc-Na). The effect of contact time (5–200 min) and pH (2–8) on Cd-uptake by the sorbent (Pull-Suc-Na) was investigated. The sorbent showed more than 90% Cd-removal in first 15 min from distilled water (DW) and GW solution, respectively. Comparison of Pull-Suc-Na with other polysaccharidal sorbents sugge…

Ripensare lo straniero. Lesbii e Parti nell'ottavo libro del Bellum civile di Lucano

2016

The eighth book of Lucan's bellum ciuile opens with the loss of Pompeius fleeing from the Thessalian battlefield. This departure, which sees the old fighter now prostrate and on which hangs a heavy fate of death, includes a double description of peoples and nations. The inhabitants of Lesbos, in which Cornelia had found shelter, offer a safe haven to Pompeius, urging him to remain. Moreover Pompeius seem to be inclined to the Parthians, the traditional enemy of Rome, but the option is destined to be defeated at the urging of Lentulus, which will convince the council of war to turn to Egypt. Within this opposing and contradictory motivations, where the reasons of the history emerge strongly …

In vitro induction of cecropin genes — an immune response in a Drosophila blood cell line

1992

The Drosophila melanogaster cell line mbn-2 was explored as a model system to study insect immune responses in vitro. This cell line is of blood cell origin, derived from larval hemocytes of the mutant lethal (2) malignant blood neoplasm (1(2)mbn). The mbn-2 cells respond to microbial substances by the activation of cecropin genes, coding for bactericidal peptides. The response is stronger than that previously described for SL2 cells, and four other tested Drosophila cell lines were totally unresponsive. Bacterial lipopolysaccharide, algal laminarin (a beta-1,3-glucan), and bacterial flagellin were strong inducers, bacterial peptidoglycan fragments gave a weaker response, whereas a formyl-m…

Dalla parte dei Decii. Lucano e la storia esemplare di Roma

2021

The paper deals with the references to the exemplary history of the Decii in Lucan’s Pharsalia. Particular attention is focused on the model of virtue and self-sacrifice towards the State they embody. However, while they ennoble the pars Pompeiana, they nevertheless show the fragility of Pompey’s fate, increasing the sense of an imminent catastrophe: the virtuous model of the Decii is in fact not replicable. The subversion produced by civil war makes it now out of date: tragedy, not history

Roma, faue coeptis. Pompeo e i Parti nell’ottavo libro della Pharsalia di Lucano

2015

The paper focuses on the section of eighth book of Pharsalia, in which Pompeius discusses with the members of the senate in order to decide the place to find refuge. Particularly, the choice that will bring Pompeius to death in Egypt is determined by the speech of Lentulus: in order to reject proposals for an alliance with the Parthians, he adopts the perspective of the ancient ethnocentrism and his prejudices. Nevertheless, in the architecture of the episode, it is determinant the rhetorical culture of the Author.

The lamellicorn beetles of southern Sardinia (Coleoptera: Scarabaeoidea)

2011

A faunistic inventory of lamellicorn beetles has been conducted in southern Sardinia (former province of Cagliari) based on literature and collection records, as well as on new fi ndings from recent fi eld expeditions (2003–2008). The taxonomic analysis of the study area revealed the occurrence of 105 species (2 Lucanidae, 2 Trogidae, 7 Geotrupidae, 1 Hybosoridae and 93 Scarabaeidae). The majority of families are represented by 100% of the known Sardinian fauna; o nly the Scarabaeidae, the most diverse family, is represented by 80.8% of its Sardinian members. Some considerations are made on the conservation status, trophic categories, chorotypes, habitat distribution and seasonal activity o…
