“The Linosa Study”: Epidemiological and heritability data of the metabolic syndrome in a Caucasian genetic isolate
2009
Abstract Background and aims Growing evidence suggests that the metabolic syndrome (MetS) has both a genetic and environmental basis. To evaluate the possibility of a further genetic analysis, we estimated prevalence rates and heritabilities for the MetS and its individual traits in the adult population of Linosa, a small and isolated Italian Island in the southern-central part of the Mediterranean Sea. Methods and results The Linosa Study (LiS) group consisted of 293 Caucasian native subjects from 51 families (123 parents; 170 offsprings). The MetS was defined according to NCEP/ATP III criteria and the following prevalence rates were calculated: hyperglycaemia 20.3%; central obesity 34.9%;…
Flemón parafaríngeo por cuerpo extraño metálico
1998
Los flemones y abcesos parafaríngeos, comunes en la era preantibiótica, son actualmente una entidad poco frecuente. Es necesario un diagnóstico y actitud terapéutica precoz para impedir acrecentar la morbimortalidad asociada. La mayoría de casos descritos se deben a perforaciones de faringe y esófago o por complicación de infecciones del tracto aerodigestivo superior. en un 15% de los casos nos encontraremos con una fase previa al abceso, denominada celulitis, sin que se haya formado colección purulenta, que puede ser solucionado con tratamiento antibiótico sin precisar drenaje quirúrgico. La paciente que presentamos empezó a referir sintomatología después de veinte años de permanencia de u…
Donation and back-donation in cis- and trans-[(η5-C5H5)Fe(η1-CO)(μ-CO)]2 tautomers: Which relative is more generous? An ETS-NOCV bond analysis
2022
The ETS-NOCV bond analysis has been exploited to quantitatively estimate donation and back-donation properties of [(η5-C5H5)]−, CO, and FeI in the cis-/trans-[(η5-C5H5)Fe(η1-CO)(μ-CO)]2 (cis-I/trans-I) tautomers. Theoretical outcomes indicate that the Fe-CO bond, regardless to the CO monoapto (η1-) or bridging (μ-) coordination, has a sizeable π Fe → CO back-bonding contribution, which is stronger in trans-I than in cis-I. Moreover, [(η5-C5H5)]− has the weakest back-donation acceptor capability. The back-bonding behaviour of the Fe → η1-CO interaction well agrees with the experimental symmetric/antisymmetric infrared νCO (sνηjavax.xml.bind.JAXBElement@fc12185-CO/aνηjavax.xml.bind.JAXBElemen…
Selective chromo-fluorogenic detection of DFP (a Sarin and Soman mimic) and DCNP (a Tabun mimic) with a unique probe based on a boron dipyrromethene …
2014
[EN] A novel colorimetric probe (P4) for the selective differential detection of DFP (a Sarin and Soman mimic) and DCNP (a Tabun mimic) was prepared. Probe P4 contains three reactive sites; i.e. (i) a nucleophilic phenol group able to undergo phosphorylation with nerve gases, (ii) a carbonyl group as a reactive site for cyanide; and (iii) a triisopropylsilyl (TIPS) protecting group that is known to react with fluoride. The reaction of P4 with DCNP in acetonitrile resulted in both the phosphorylation of the phenoxy group and the release of cyanide, which was able to react with the carbonyl group of P4 to produce a colour modulation from pink to orange. In contrast, phosphorylation of P4 with…

On the structure of 3-acetylamino-5-methyl- 1,2,4-oxadiazole and on the fully degenerate rearrangements (FDR) of its anion: a stimulating comparison …
2009
An accurate crystal structure determination has provided evidence for a planar conformation for 3-acetylamino-5-methyl-1,2,4-oxadiazole (5), in agreement with quantum-mechanical calculations in the gas phase. In the crystal, a series of strong intermolecular N7H7...O9 hydrogen bonds link the amido groups of different molecules, causing the formation of infinite parallel ordered chains. The effect of the DMSO solvent on the energy and charge distribution of compound 5 and on its relevant 5S anion, involved in a fully degenerate rearrangement (FDR), has been deepened by quantum-mechanical DFT calculations. The calculated energy barrier for the FDR increases in going from in vacuo to DMSO, in …
Unsteady Separation and Navier-Stokes Solutions at High Reynolds Numbers
2010
We compute the numerical solutions for Navier-Stokes and Prandtl’s equations in the case of a uniform bidimensional flow past an impulsively started disk. The numerical approx- imation is based on a spectral methods imple- mented in a Grid environment. We investigate the relationship between the phenomena of unsteady separation of the flow and the exponential decay of the Fourier spectrum of the solutions. We show that Prandtl’s solution develops a separation singularity in a finite time. Navier-Stokes solutions are computed over a range of Reynolds numbers from 3000 to 50000. We show that the appearance of large gradients of the pressure in the stream- wise direction, reveals that the visc…
Caratterizzazione genetica della razza Bracco Francese ed analisi comparative con le principali razze canine
2018
Il sequenziamento del genoma canino ha contribuito a migliorare l’accuratezza delle stime di diversità genetica ed ha anche generato diversi studi sulle relazioni tra le diverse razze allevate (Vaysse et al., 2011; Parker et al., 2017). Tuttavia, alcune razze rimangono ancora poco caratterizzate. È il caso del Bracco Francese tipo Pyrénées. Lo scopo di questo lavoro è stato quello di caratterizzare a livello genomico la razza e studiarne le relazioni con altre razze allevate nel mondo. Sono stati raccolti i campioni di sangue da 48 individui. La genotipizzazione è stata condotta mediante l’Illumina CanineHD BeadChip (173.662 marcatori). Diversi parametri di diversità genetica sono stati cal…
Characterization of Brassica fruticulosa seeds
2009
The structure and vitamin E (tocopherol and tocotrienol), fatty acid and phytosterol content and composition of seeds of Brassica fruticulosa Cyr. (Brassicaceae) were characterized. Seed size and elevated content of γ-tocotrienol, and γ- tocopherol and low of α- tocopherol can be useful for distinguishing seeds of B. fruticolosa from those of Sicilian Brassica sect. Brassica. The concentration of the tocotrienol is about one third of the vitamin E content. This profile makes this wild species worth to be recovered as food source and its germplasm preserved in a gene bank.
