Microbial production of biopolymers from the renewable resource wheat straw.
2014
Aims Production of poly-s-hydroxybutyrate (PHB) and the chemical basic compound lactate from the agricultural crop ‘wheat straw’ as a renewable carbon resource. Methods and Results A thermal pressure hydrolysis procedure for the breakdown of wheat straw was applied. By this means, the wheat straw was converted into a partially solubilized hemicellulosic fraction, consisting of sugar monomers, and an insoluble cellulosic fraction, containing cellulose, lignin and a small portion of hemicellulose. The insoluble cellulosic fraction was further hydrolysed by commercial enzymes in monomers. The production of PHB from the sugar monomers originating from hemicellulose or cellulose was achieved by …
Antibiotic prophylaxis in antenatal nonrefluxing hydronephrosis, megaureter and ureterocele
2012
Observation is a conservative management option in infants with nonrefluxing hydronephrosis, primary nonrefluxing megaureter and ureterocele diagnosed postnatally following antenatal detection of hydronephrosis. Antibiotic prophylaxis might be a sensible regimen under these circumstances to prevent UTI in this population who are potentially at increased risk. However, studies examining the efficacy of prophylactic antibiotics are sparse in this setting. For each condition, prophylactic policies seem extremely variable, and UTI rates vary widely with comparable rates reported between patients followed on and off antibiotics. Overall, antibiotic prophylaxis seems unnecessary in patients with …

3D-Reconstruction of a Giant Posidonia oceanica Beach Wrack (Banquette): Sizing Biomass, Carbon and Nutrient Stocks by Combining Field Data With High…
2022
Beach wracks are temporary accumulations of vegetal detritus that can be found along coastlines all over the world. Although beach wracks are often perceived as a nuisance for beach users, they play a crucial ecological role in carbon and nutrient connectivity across ecosystem boundaries, especially when they reach a relevant size, as in the case of the wedge-shaped seagrass accumulations called banquette. In this study, three-dimensional mapping of a giant Posidonia oceanica banquette was carried out for the first time using high-resolution UAV photogrammetry combined with field sampling and compositional and chemical analysis. The combined approach allowed a reliable estimation of the amo…

Archeologia dell'antico, archeologia del moderno
2016
Il saggio, partendo dal caso applicativo della Centrale elettrica di Augusta, esprime una riflessione sul valore del patrimonio industriale che, ove riconosciuto tale, è bene da slavguardare e non da demolire, per trasformarlo in una risorsa. Propone pertanto un programma metodologico per il suo recupero e la valorizzazione, in itinerario congiunto con l'adicente sito archeologico di Megara Hyblea.
I confini dell'identità. Un caso di comunicazione paradossale nella Sicilia greca arcaica
1990
Contro l'opinione corrente che vede la colonizzazione come occasione per costruire una rappresentazione storiografica e una memoria culturale della superiorità dei Greci colonizzatori rispetto agli indigeni, si prende in esame un caso eccezionale di coloni Greci scacciati da altri Greci e "soccorsi" dai Siculi indigeni con una procedura che rimette in gioco i confini e gli spazi dell'identità etnica.
Sustained activation of mTOR pathway in embryonic neural stem cells leads to development of tuberous sclerosis complex-associated lesions
2011
SummaryTuberous Sclerosis Complex (TSC) is a multisystem genetic disorder characterized by hamartomatous neurological lesions that exhibit abnormal cell proliferation and differentiation. Hyperactivation of mTOR pathway by mutations in either the Tsc1 or Tsc2 gene underlies TSC pathogenesis, but involvement of specific neural cell populations in the formation of TSC-associated neurological lesions remains unclear. We deleted Tsc1 in Emx1-expressing embryonic telencephalic neural stem cells (NSCs) and found that mutant mice faithfully recapitulated TSC neuropathological lesions, such as cortical lamination defects and subependymal nodules (SENs). These alterations were caused by enhanced gen…
