The small protein TrpM modulates morpho-physiological differentiation in Streptomyces coelicolor

2017

TrpM, a small protein of 63 amino acids, is encoded by a gene of the trpCMBA locus involved in tryptophan biosynthesis in the model actinomycete Streptomyces coelicolor. Indeed, the trpM knock-out mutant strain is characterized by a delayed growth on minimal medium, smaller aerial hyphae, and reduction of both spore and antibiotic actinorhodin production in comparison with the wild-type strain. These observations are in agreement with proteomic analyses which highlighted a role for TrpM in controlling i) tryptophan production through precursor availability and, thus ii) bacterial growth and morpho-physiological differentiation. To further elucidate the role of TrpM, a S. coelicolor trpM kno…

Architettura e paesaggio tra forma e tempo

2017

Tra formazione e professione vi è la necessità di instaurare un rapporto continuo senza costringere la didattica ad un adeguamento acritico. Pensando, cioè, che quest’ultima, come un sismografo, debba seguire qualunque oscillazione proveniente dal mondo del lavoro. Nel verificare delle esigenze e nell‘apportare delle modifiche ai contenuti della formazione vi è un comprensibile attrito, perché in architettura vi sono dei principi immutabili. Per questi “enunciati base”, così definiti da Aldo Rossi, si immaginano degli urti o, se si preferisce, degli strappi, provenienti dall’esterno, e quasi mai dalla stessa università. In negativo, invece, si nota di primo acchito come la divisione in sett…

Spazio e autobiografia nella poesia di Giorgio Caproni. Le “città dell’anima” e i luoghi descritti “per denominazione”

2017

Il saggio propone un attraversamento delle diverse stagioni dell’opera poetica di Giorgio Caproni, volto a costruire una ‘mappa’ della topografia dell’autore passando in rassegna non solo alcuni dei principali luoghi della sua poesia, ma anche modi e forme in cui la “funzione spazio” viene in essa declinata. la città, in particolare le cosiddette “città dell’anima”, Genova e Livorno, e altri “luoghi descritti per enumerazione” diventano le tappe di un percorso che avviene attraverso luoghi immaginari e spazi realmente esistiti. gli uni e gli altri si combinano a costituire itinerari di volta in volta diversi ma capaci di dare solidità a un unico “luogo preciso”: il mondo interiore del poeta…

Restorative justice and criminal proceedings in Italy

2017

In regards to restorative justice, Italian judicial system is one-step behind in respect to other systems. Conflict is traditionally based on an authoritative model, which is slowly and gradually opening up to a conciliationkind model. Our system also, which is still strongly based on penal action compulsoriness principle, is starting to be acquainted with these different models. At a legislative level, restorative justice is still not fully recognized. But by considering restorative justice as a tool including any conciliation or reparation formality, there are other institutions, foreseen and disciplined by Italian code of criminal procedure, that lead back to it.

El copiloto suicida : problemas médico legales detectados en el accidente aéreo de Germanwings

2017

The plane crash of Germanwings, which happened in France in 2015, was an event of great mediatic repercussion, with a total of one hundred fifty mortal victims. People implied in the case were Andreas Lubitz -copilot-, the academy of formation of Lufthansa -a German airline company- and the sanitary professionals who took care of the copilot. It happened to be a suicide act which was premeditated. The protagonist was off work at the time when the accident occured. We question the rigidity of the medical examination which determines the aptitude to pilot, as well as its control by the aviation academy and by the airway company. We determined whether Lubitz was capable, at a psychic level, of…

The Power of the Young Town

In Italy, after the Second World War, according to Fanfani and Tupini’s laws (1949), INA-casa and its procuring entities’ ventures made a motor of urban renewal from the enthusiasm and the commitment of many entrepreneurs and public administrators. In Palermo, the agricultural lands began to include new neighbourhoods that quickly merged with the historic and nineteenth-twentieth century centre. In the fifties, between the town and its geographic limits (the mountains of the Corona dei Colli) a beltway has been hypothesized. It was a founding board (Culotta, 2005). In the sixties, it was the spine of an expanding urban fabric that absorbed citrus groves, vineyards, olive groves, field of fl…

Lake La Cruz, an Iron-Rich Karstic Meromictic Lake in Central Spain

2017

Laguna de la Cruz (Lake La Cruz ) is a small karstic meromictic lake located in Central-Eastern Spain. Its biogenic meromixis (originated ca.1660) is favoured by the high relative depth and the steep doline walls. Calcium and magnesium bicarbonate are the main salts. The monimolimnion permanently spans from 18 m to the lake bottom (ca.21 m), whereas thermal stratification occurs above from April to October. Steep chemical gradients appear both at the bottom of the metalimnion (seasonally) and, permanently, at the permanent chemocline (16–18 m). Nutrients in surface waters decay as stratification advances, but deeper they are abundant. Linked to physical and chemical gradients, sharply strat…

Formation of a dinuclear and a trinuclear Ni(II) complex on slight variation of experimental conditions: Structural analysis and magnetic properties

2017

Abstract A diphenoxido bridged dinuclear Ni(II) complex [Ni2L2(NO2)2] (1) and a μ2 and μ3-phenoxido, μ3-hydroxido, and μ2-nitrito (1κO:2κN) bridged trinuclear Ni(II) complex [Ni3L3(OH)(NO2)]·ClO4 (2), have been synthesized using a tridentate reduced Schiff base ligand HL (HL = 2-[(2-dimethylamino-ethylamino)-methyl]-phenol). Both complexes were characterized by X-ray structure determination and variable-temperature magnetic susceptibility measurements. In both complexes the nickel atoms are six-coordinated with a distorted octahedral environment. The interesting feature of the trimeric complex 2 is that the three mononuclear units are assembled around a μ3-hydroxido ion in such a way that t…

Image Colorization Method Using Texture Descriptors and ISLIC Segmentation

We present a new colorization method to assign color to a grayscale image based on a reference color image using texture descriptors and Improved Simple Linear Iterative Clustering (ISLIC). Firstly, the pixels of images are classified using Support Vector Machine (SVM) according to texture descriptors, mean luminance, entropy, homogeneity, correlation, and local binary pattern (LBP) features. Then, the grayscale image and the color image are segmented into superpixels, which are obtained by ISLIC to produce more uniform and regularly shaped superpixels than those obtained by SLIC, and the classified images are further post-processed combined with superpixles for removing erroneous classific…

Nowadays, it is widely accepted that wastewater treatment plants (WWTPs) are significant sources of greenhouse gas (GHG) emission, contributing to the anthropogenic sources. Among the GHG emitted from WWTPs, nitrous oxide (N2O) has been identified of having the major interest/concern, since its high global warming potential (GWP), is 298 times higher than that of CO2 and also to its capability to react with stratospheric ozone causing the layer depletion. Up to now, most of the experimental investigations have been carried out on conventional activated sludge (CAS) processes. The knowledge of N2O emission from advanced technologies such membrane bioreactors (MBRs) is still very limited. The…

Mast cells contribute to autoimmune diabetes by releasing interleukin-6 and failing to acquire a tolerogenic IL-10+ phenotype

2017

Mast cells (MCs) are innate immune cells that exert positive and negative immune modulatory functions capable to enhance or limit the intensity and/or duration of adaptive immune responses. Although MCs are crucial to regulate T cell immunity, their action in the pathogenesis of autoimmune diseases is still debated. Here we demonstrate that MCs play a crucial role in T1D pathogenesis so that their selective depletion in conditional MC knockout NOD mice protects them from the disease. MCs of diabetic NOD mice are overly inflammatory and secrete large amounts of IL-6 that favors differentiation of IL-17-secreting T cells at the site of autoimmunity. Moreover, while MCs of control mice acquire…

Structural evolution of CO2 filled pure silica LTA zeolite under high-pressure high-temperature conditions

2017

[EN] The crystal structure of CO2-filled pure-SiO2 LTA zeolite has been studied at high pressures and temperatures using synchrotron-based X-ray powder diffraction. Its structure consists of 13 CO2 guest molecules, 12 of them accommodated in the large alpha-cages and one in the beta-cages, giving a SiO2/CO2 stoichiometric ratio smaller than 2. The structure remains stable under pressure up to 20 GPa with a slight pressure-dependent rhombohedral distortion, indicating that pressure-induced amorphization is prevented by the insertion of guest species in this open framework. The ambient temperature lattice compressibility has been determined. In situ high-pressure resistive-heating experiments…
