2013

<em>Sarcodontia crocea</em> (Schwein.) Kotl., <em>Oligoporus mappa</em> (Overh. & Lowe) Gilbn. & Ryvarden and <em>Inonotus rickii</em> (Pat.) D.A. Reid. are reported for the first time from Sicily (southern Italy). Ecological and distributive features on the three relevant species are also here provided.

Changes in gene expression during adaptation of Listeria monocytogenes to the soil environment

2011

project SEST 009; International audience; Listeria monocytogenes is a ubiquitous opportunistic pathogen responsible for listeriosis. In order to study the processes underlying its ability to adapt to the soil environment, whole-genome arrays were used to analyse transcriptome modifications 15 minutes, 30 minutes and 18 h after inoculation of L. monocytogenes EGD-e in soil extracts. Growth was observed within the first day of incubation and large numbers were still detected in soil extract and soil microcosms one year after the start of the experiment. Major transcriptional reprofiling was observed. Nutrient acquisition mechanisms (phosphoenolpyruvate-dependent phosphotransferase systems and…

Oligopeptidipäällysteiset kultananopartikkelit lääketieteellisissä sovelluksissa

2016

Pro Gradu -tutkielmassa käsitellään oligopeptidipäällysteisten kultananopartikkeleiden sovelluksia lääketieteessä. Tutkielmassa käydään läpi kultananopartikkeleiden yleisiä ominaisuuksia sekä niiden soveltuvuutta biologisiin ja lääketieteellisiin sovelluksiin. Lisäksi esitellään yleisimmät kultananopartikkeleiden päällystyksessä käytettävät oligopeptidit ja kuvataan erityyppisille oligopeptidipäällysteisille kultananopartikkeleille kehiteltyjä lääketieteellisiä sovelluksia, joihin lukeutuvat muun muassa syöpähoito, biologinen kuvantaminen, kolorimetriset biomolekyylianalyysit ja lääkeaineiden kohdennettu kuljetus. Kokeellisessa osassa pyrittiin valmistamaan tiolifunktionalisoitu oligopeptid…

The Role of Orbital Symmetries in Enforcing Ferromagnetic Ground State in Mixed Radical Dimers

2018

One of the first steps in designing ferromagnetic (FM) molecular materials of p-block radicals is the suppression of covalent radical-radical interactions that stabilize a diamagnetic ground state. In this contribution, we demonstrate that FM coupling between p-block radicals can be achieved by constructing mixed dimers from different radicals with differing symmetries of their singly occupied molecular orbitals. The applicability of this approach is demonstrated by studying magnetic interactions in organic radical dimers built from different derivatives of the well-known phenalenyl radical. The calculated enthalpies of dimerization for different homo- and heterodimers show that the formati…

Antifouling Systems Based on a Polyhedral Oligomeric Silsesquioxane-Based Hexyl Imidazolium Salt Adsorbed on Copper Nanoparticles Supported on Titania

2023

The reaction of octakis(3-chloropropyl)octasilsesquioxane with four equivalents of 1-hexylimidazole or 1-decylimidazole gave two products labelled as HQ-POSS (hexyl-imidazolium quaternized POSS) and DQ-POSS (decyl-imidazolium quaternized POSS) as regioisomer mixtures. An investigation of the biological activity of these two compounds revealed the higher antimicrobial performances of HQ-POSS against Gram-positive and Gram-negative microorganisms, proving its broad-spectrum activity. Due to its very viscous nature, HQ-POSS was adsorbed in variable amounts on the surface of biologically active oxides to gain advantages regarding the expendability of such formulations from an applicative perspe…

Self-Complementary Dimers of Oxalamide-Functionalized Resorcinarene Tetrabenzoxazines

2018

Self‐complementarity is a useful concept in supramolecular chemistry, molecular biology and polymeric systems. Two resorcinarene tetrabenzoxazines decorated with four oxalamide groups were synthesized and characterized. The oxalamide groups possessed self‐complementary hydrogen bonding sites between the carbonyls and amide groups. The self‐complementary nature of the oxalamide groups resulted in self‐included dimeric assemblies. The hydrogen bonding interactions within the tetrabenzoxazines gave rise to the formation of dimers, which were confirmed by single‐crystal X‐ray diffractions analysis and supported by NMR spectroscopy and mass spectrometry. The self‐included dimers were connected b…

Parallel Behaviour – Primary Evidence of an Agreement

2013

Abstract The distinction between legitimate oligopoly and cartels is tackled by each competition authority. A parallel behaviour in an oligopolistic market might be seen as an anchor for competition's effectiveness, given that companies are required to respond to the decisions of other competitors, trying to keep a realistic and competitive position to ensure welfare. Cartels offer an opposite perspective of what competition really means. Apart from the observation of the econometrical model presented in the article, the final assessment should consider the particularities of the legal and economic environment, to conclude on the existence of a cartel based on reasonable grounds.

Entering the Nano-Cosmos of the Cell by Means of Spatial Position Determination Microscopy (SPDM): Implications for Medical Diagnostics and Radiation…

2013

During the last 20 years fluorescence light microscopy has made an enormous progress towards fluorescence nanoscopy in order to elucidate the nanostructural organization of cellular machineries beyond classical limits of resolution in light microscopy. One of these novel techniques is Spatial Position Determination Microscopy (SPDM), an approach of molecular localization microscopy based on the application of specific fluorescence labelling of cellular structures by means of dyes that undergo reversible photobleaching resulting in blinking effects during image acquisition. This blinking allows spectral separation of individual molecules and thus precise localization and distances measuremen…

Role of FODMAPs in Patients With Irritable Bowel Syndrome.

2015

Irritable bowel syndrome (IBS) is a condition characterized by abdominal pain, bloating, flatus, and altered bowel habits. The role of dietary components in inducing IBS symptoms is difficult to explore. To date, foods are not considered a cause but rather symptom-triggering factors. Particular interest has been given to the so-called FODMAPs (fermentable oligo-, di-, and monosaccharides and polyols). We aimed to summarize the evidence from the most common approaches to manage suspected food intolerance in IBS, with a particular interest in the role of FODMAPs and the effects of a low FODMAP diet. We reviewed literature, consulting PubMed and Medline by using the search terms FODMAP(s), fru…
