The Impact of Single-Level ACDF on Neural Foramen and Disc Height of Surgical and Adjacent Cervical Segments: A Case-Series Radiological Analysis
2023
Background: ACDF has become one of the established procedures for the surgical treatment of symptomatic cervical spondylosis, showing excellent clinical results and effective improvements in neural functions and neck pain relief. The main purpose of ACDF is neural decompression, and it is considered by some authors as an indirect result of the intervertebral distraction and cage insertion and the consequent restoration of the disc space and foramen height. Methods: Radiological data from 28 patients who underwent single-level ACDF were retrospectively collected and evaluated. For neural foramen evaluation, antero-posterior (A-P) and cranio-caudal (C-C) diameters were manually calculated; fo…
LA CONVENANCE DE L’ORNEMENT : UNE QUESTION ÉTHIQUE ?
2019
Nell'era contemporanea, in cui gli architetti sono spesso alla ricerca di una bellezza spettacolare, la questione dell'ornamento trova un'importante attualità nel dibattito filosofico e architettonico. La domanda è se l'ornamento non abbia una dimensione etica. Per rispondere, studierò qui tre momenti storici decisivi di questo dibattito: la teoria dell'armonia di Alberti, l'approccio della scuola di Chicago alle relazioni di forma e funzione (LH Sullivan e J. Root) e la critica dell'ornamento in A. Loos. Pur appartenendo a diversi orizzonti culturali, queste teorie possono far luce sul dibattito contemporaneo svelando la dimensione etica e non solo quella estetica dell'ornamento. In contem…
Diversifying crop rotations with temporary grasslands: potentials for weed management and farmland biodiversity
2010
Fruchtfolgen können dazu dienen, die kontinuierliche Selektion von Unkrautarten zu verhindern, die an eine bestimmte Kultur angepasst sind. Dies könnte dem Unkrautmanagement, der Einsparung von Herbiziden, und der Biodiversität dienen. Heutige, sehr einfache Furchtfolgen könnten durch mehrjährige Futterkulturen diversifiziert werden. Die Einflüsse solcher mehrjähriger Kulturen auf Unkräuter wurden in vier Ansätzen untersucht : 1) Vegetationsaufnahmen auf 632 Feldern in Westfrankreich zeigten, dass die Unkrautzusammensetzung zwischen mehrjährigen Futterkulturen und einjährigen Kulturen stark variiert. Der Vergleich von Feldern vor, während und nach mehrjährigen Futterkulturen legte nahe, das…
Technical improvements for analysis of recalcitrant proteins by LC-MS : the mycorrhiza responsive membrane proteome as a case study
2012
Arbuscular mycorrhizas (AM) are widespread symbiotic associations between plant roots and AM fungi. Deep membrane alterations are the foremost morphological changes occurring in the host plant in response to AM symbiosis. Two-dimensional gel electrophoresis (2-DE) is the workhorse method in AM proteomics. Membrane proteins are under-represented in 2-DE because of their hydrophobicity, low abundance, and precipitation at their isoelectric point, thereby few are the identified membrane proteins involved in sustaining the AM symbiosis. Membrane proteomics is still challenging due to 2-DE related shortcomings, however latest trends and advancements in mass spectrometry (MS)-based quantitative p…
Evidence for region-specific effects of glucagone-like peptide-2 in mouse stomach

La chiesa e il convento di San Domenico a Cagliari nel XVI secolo.
Questa ricerca riguarda il convento di San Domenico a Cagliari e la riforma della fabbrica attuata nel corso del Cinquecento. Fondato nel borgo di Villanova nel versante est del castello di Cagliari nella seconda metà del XIII secolo, il convento di San Domenico raggiunse la sua massima espansione a partire dagli anni sessanta del XVI secolo, in seguito probabilmente all’introduzione nel convento della riforma domenicana. Le riforme spirituali e materiali del convento fecero parte di più vasto movimento di rinnovamento che coinvolse su larga scala il panorama sardo nel secondo Cinquecento, dovuto a molteplici fattori tra cui il riformismo monarchico di Filippo II e le riforme religiose avvi…
Tetrameric and Dimeric [N∙∙∙I+∙∙∙N] Halogen-Bonded Supramolecular Cages
2017
Tripodal N‐donor ligands are used to form halogen‐bonded assemblies via structurally analogous Ag+‐complexes. Selective formation of discrete tetrameric I6L4 and dimeric I3L2 halonium cages, wherein multiple [N⋅⋅⋅I+⋅⋅⋅N] halogen bonds are used in concert, can be achieved by using sterically rigidified cationic tris(1‐methyl‐1‐azonia‐4‐azabicyclo[2.2.2]octane)‐mesitylene ligand, L1(PF6)3, and flexible ligand 1,3,5‐tris(imidazole‐1‐ylmethyl)‐2,4,6‐trimethylbenzene, L2, respectively. The iodonium cages, I6L14(PF6)18 and I3L22(PF6)3, were obtained through the [N⋅⋅⋅Ag+⋅⋅⋅N]→ [N⋅⋅⋅I+⋅⋅⋅N] cation exchange reaction between the corresponding Ag6L14(PF6)18 and Ag3L22(PF6)3 coordination cages, prepare…

Use of translational genomics to identify genes important for legume seed filling
2013
International audience; Translational genomics, i.e., the transfer of genetic information from model species to cultivated crops, is on the brink of revolutionizing plant breeding. The recent publication of genomic sequences for several cultivated legumes is also accelerating this process. For pea, recent highthroughput RNA sequencing, and the prospect of a genome sequencing project, will further accelerate the transfer of information from the Medicago truncatula model to the cultivated crop. We have been using genomics approaches with Medicago as a tool to identify key genes determining seed yield and composition in closely related legumes. Analyses of the proteome and transcriptome of the…
Identification of mycorrhiza-regulated genes with arbuscule development-related expression profile
2004
Suppressive subtractive hybridisation was applied to the analysis of late stage arbuscular mycorrhizal development in pea. 96 cDNA clones were amplified and 81, which carried fragments more than 200 nt in size, were sequence analysed. Among 67 unique fragments, 10 showed no homology and 10 were similar to sequences with unknown function. RNA accumulation of the corresponding 67 genes was analysed by hybridisation of macro-arrays. The cDNAs used as probes were derived from roots of wild type and late mutant pea genotypes, inoculated or not with the AM fungus Glomus mosseae. After calibration, a more than 2.5-fold mycorrhiza-induced RNA accumulation was detected in two independent experiments…
