First report of brown rot and wilt of fennel caused by Phytophthora megasperma in Italy
2019
Fennel (Foeniculum vulgare Mill. var. azoricum (Mill.) Thell.) in the Apiaceae family is native to southern Europe and southwestern Asia. It is an economically important crop in Italy that produces approximately 85% of all fennel worldwide. The main producing regions are Apulia, Campania, Latium, and Calabria. During the late winter of 2004 in the Crotone Province of the Calabria Region, following heavy rains, patches of fennel plants with symptoms of brown, soft rot of the bulb-like structure formed by the thickened leaf bases, development of yellow leaves, stunting, and wilting of the entire plant were observed in fields. A homothallic Phytophthora sp. was isolated consistently from the …

La prehistoria de Ibiza y Formentera: estado actual de la investigación
1988
The study of the prehistory of Ibiza and Formentera, the two small islands that form the Pityussae sub-group within the Balearic archipelago, began a few years ago as a consequence of the discovery and excavation of the megalithic chamber tomb of a Ca Na Costa on Formentera. Before then, prehistorians were still in doubt as to whether these islands had been occupied before the Phoenician colonisation. Many sites have come to light in the last decade, allowing us to present for the first time a general survey of the prehistoric settlement of the islands. Nevertheless, many problems are still unsolved, and new excavations are needed to establish the apparently complex cultural sequence, which…
Biological activity of Bacillus spp. evaluated on eggs and larvae of red palm weevil Rhynchophorus ferrugineus
2014
This study was conducted to characterize the Bacillus populations associated with dead Rhynchophorus ferrugineus, to develop a biological control for the red palm weevil. Dead adult beetles, collected throughout Sicily, were used for isolating internal and external spore forming bacteria (SFB) microbiota. The isolates, preliminarily allotted to the Bacillaceae family, were tested at 4 concentrations (103 to 106 CFU/mL) for their ability to inhibit hatching of eggs of R. ferrugineus and were used at 106 CFU/mL to monitor their insecticidal activity against 10 day-old larvae. Total amounts of SFB measured outside the skeleton and in the inners part of the beetles were 5.59-6.94 and 5.17-7.05 …
Reportage da Berlino megalopoli

Editoriale
2020
Il numero 7 di AGATHÓN raccoglie saggi, studi, ricerche e progetti sul tema dal titolo ‘Dal Mega al Nano: la Complessità del Progetto Multiscalare’, tema indissolubilmente legato alla sempre maggiore richiesta di trans e multidisplinarietà del progetto. La capacità di effettuare ‘salti di scala’, di agire su scale diverse e di costruirne di nuove o di mutare il senso di quelle comunemente accettate è una pratica comune dell’approccio al progetto, e riguarda da sempre gli architetti, gli ingegneri, i designer e gli artisti, nei molteplici significati simbolici e reali della misura di un territorio, di una città, di un’architettura e di un oggetto. I concetti di scala e di misura sono indispe…
Prevention of chemotherapy-induced anemia and thrombocytopenia by constant administration of stem cell factor.
2011
Abstract Purpose: Chemotherapy-induced apoptosis of immature hematopoietic cells is a major cause of anemia and thrombocytopenia in cancer patients. Although hematopoietic growth factors such as erythropoietin and colony-stimulating factors cannot prevent the occurrence of drug-induced myelosuppression, stem cell factor (SCF) has been previously shown to protect immature erythroid and megakaryocytic cells in vitro from drug-induced apoptosis. However, the effect of SCF in vivo as a single myeloprotective agent has never been elucidated. Experimental Design: The ability of SCF to prevent the occurrence of chemotherapy-induced anemia and thrombocytopenia was tested in a mouse model of cisplat…
Chemokine stromal cell-derived factor-1alpha modulates VLA-4 integrin-dependent adhesion to fibronectin and VCAM-1 on bone marrow hematopoietic proge…
2001
Stromal cell-derived factor-1alpha (SDF-1alpha) is a potent chemoattractant for hematopoietic progenitor cells (HPC), suggesting that it could play an important role during their migration within or to the bone marrow (BM). The integrin VLA-4 mediates HPC adhesion to BM stroma by interacting with CS-1/fibronectin and VCAM-1. It is required during hematopoiesis and homing of HPC to the BM. As HPC migration in response to SDF-1alpha might require dynamic regulation of integrin function, we investigated if SDF-1alpha could modulate VLA-4 function on BM CD34(hi) cells.CD34(hi) BM cells and hematopoietic cell lines were tested for the effect of SDF-1alpha on VLA-4-dependent adhesion to CS-1/fibr…
A Km-scale Cretaceous slope in western Sicily (Italy)
2017
Cretaceous slopes are well known from many regions of the world, since they are among the most prone depositional systems to host hydrocarbons. As far as Italy, in spite of fully described examples as the Majella and Gargano escarpments, detailed sedimentological and biostratigraphic studies from Sicily are not available, although the presence of slope carbonates of Cretaceous age in northwestern Sicily, is mentioned in several papers dealing with regional geology or geological mapping. The Cretaceous slope carbonates from this area, i.e. the San Vito Lo Capo Peninsula, belong to several thrust sheets of the Maghrebian chain. The stratigraphic setting in these tectonic units allows to recon…
Castillejo del Bonete (Terrinches, Ciudad Real): un complejo tumular prehistórico de la Cultura de las Motillas en el Alto Guadalquivir
2014
Situado en las estribaciones orientales de Sierra Morena, dentro de la cuenca hidrológica del Guadalquivir, Castillejo del Bonete es un gran complejo arquitectónico que consta de una cueva monumentalizada mediante estructuras varias, entre las que destacan varios corredores megalíticos y túmulos, todos ellos asociados a contextos funerarios y depósitos de ofrendas. El presente artículo se centra en la explicación detallada de los elementos que integran este complejo constructivo para posteriormente discutir el avance que supone para la investigación de la Prehistoria Reciente en La Mancha. Castillejo del Bonete tiene el potencial de convertirse en un yacimiento clave para la comprensión de …
