High-resolution spectroscopy of two metal-poor red giants: HD 232078 and HD 218732
2010
An abundance analysis for 35 chemical elements based on a high-resolution (R = 67 000) optical spectra of two metal-poor ([Fe/H] ≈ - 1.50) halo red giants, HD 232078 and HD 218732, is presented. Abundances of 10 chemical elements were derived for the first time. Both red giants are chromospherically active and optically variable, located close to the red giant branch tip. Abundances of both stars generally follow typical halo star abundance distribution, while HD 218732 should have experienced a deep mixing episode and could be a first ascent asymptotic giant branch star.
The human protein Hugl-1 substitutes for Drosophila lethal giant larvae tumour suppressor function in vivo
2004
Drosophila lethal giant larvae: (lgl), discs large (dlg) and scribble (scrib) are tumour suppressor genes acting in a common pathway, whose loss of function leads to disruption of cell polarity and tissue architecture, uncontrolled proliferation and growth of neoplastic lesions. Mammalian homologues of these genes are highly conserved and evidence is emerging concerning their role in cell proliferation control and tumorigenesis in humans. Here we investigate the functional conservation between Drosophila lethal giant larvae and its human homologue Hugl-1(Llgl1). We first show that Hugl-1 is lost in human solid malignancies, supporting its role as a tumour suppressor in humans. Hugl-1 expres…
Evolution and functional differentiation of recently diverged phytochelatin synthase genes from Arundo donax L.
2019
Plant phytochelatin synthases undergo evolutionarily rapid functional differentiation after duplication, allowing fast and precise adjustment of metal detoxification capacity by modulation of both transcription and enzymatic activity.

Giuseppe Samonà e la “spina dorsale” di Gibellina Nuova
2020
Nel 1970 Giuseppe Samonà coordina il gruppo di progettazione formato da Vittorio Gregotti, Gianni Pirrone e Alberto Samonà per il Progetto del Centro civico, commerciale e culturale di Gibellina Nuova. Del piano è realizzato il municipio e poi, rielaborato e in altro luogo, il teatro. I monumenti, fondati su un asse pedonale in quota connesso a un suolo artificiale articolato, esprimono l’unità architettura – urbanistica e anticipano, per certi versi, una riflessione successiva del Direttore dello IUAV sulla dialettica fra urbano e rurale.
La città e gli alberi. Progetti di Gianni Pirrone per Palermo e Gibellina Nuova
2022
In the wake of the historical tradition of landscape architecture, the architect Gianni Pirrone (Palermo, 1924-2004) understood the need to look at urban greenery as a figure and not as a background, or frame of buildings and neighbourhoods. Pirrone consigns to an imminent future - a time that escapes our eyes today - the need for a new relationship between ecological reserves, gardens, residual areas and the city. The projects for the Botanical Garden and the Oreto Valley in Palermo and for the civic center of Gibellina Nuova solicit for a current reflection, making an interesting starting hypothesis. The vegetation, the colours, the water, the silence can take over and extend into an unpr…
ARCHITETTURA E VEGETAZIONE URBANA. I progetti di Gianni Pirrone per il sistema Orto Botanico - Oreto a Palermo e per Gibellina Nuova

Following the historical tradition of the Garden Architecture, in the 1970s, the architect Gianni Pirrone (Palermo 1924-2004) understood the need to look at urban greenery as a figure and not as a background, or frame or area pertaining to buildings and neighborhoods. Pirrone consigns an imminent future - a time that escapes our today’s eyes - the need for a new relationship between ecological reserves, gardens, residual areas, and the city. The projects for the Botanical Garden and the Oreto Valley in Palermo and for the civic center of Gibellina Nuova provokes a current reflection; they are also an interesting starting hypothesis.
