DALLA PUNIZIONE ALLA RIPARAZIONE? ASPIRAZIONI E LIMITI DELL’ENNESIMA RIFORMA ANTICORRUZIONE (LEGGE N. 69/2015)
2015
Il testo propone un commento critico delle norme anticorruzione contenute nella l. 69/2015. La tesi di fondo è che la dichiarata aspirazione a privilegiare una strategia riparatoria è in realtà smentita dal contenuto effettivo di molte delle norme introdotte, le quali mantengono invece un tenore saldamente punitivo.

Untargeted Antifungal Treatment Strategies for Invasive Candidiasis in Non-neutropenic Critically Ill Patients: Current Evidence and Insights
2017
Purpose of Review: The purpose of this study was to provide an overview and insights on important new concepts on untargeted antifungal treatment strategies, namely prophylaxis pre-emptive and empiric treatments for the management of invasive candidiasis (IC) in non-neutropenic critically ill patients. Recent Findings: Recently, clinical practice guidelines provided recommendation for the management of IC. However, results from recent trials and systematic reviews questioned the effect of untargeted antifungal treatment strategies, especially in terms of survival benefits in non-neutropenic patients, even with septic shock. Summary: Widespread use of untargeted antifungal treatment strategi…
T cells can present antigens such as HIV gp120 targeted to their own surface molecules
1988
To trigger class II-restricted T cells, antigen presenting cells have to capture antigens, process them and display their fragments in association with class II molecules. In most species, activated T cells express class II molecules; however, no evidence has been found that these cells can present soluble antigens. This failure may be due to the inefficient capture, processing or display of antigens in a stimulatory form by T-cells. The capture of a soluble antigen, which is achieved by nonspecific mechanisms in macrophages and dendritic cells, can be up to 10(3) times more efficient in the presence of surface receptors, such as surface immunoglobulin on B cells that specifically bind anti…
CD2-mediated autocrine growth of herpes virus saimiri-transformed human T lymphocytes.
1992
Herpes virus saimiri (HVS) immortalizes T lymphocytes from a variety of primates and causes acute T cell lymphomas and leukemias in nonnatural primate hosts. Here we have analyzed the requirements for growth of three HVS-transformed human T cell lines. The cells expressed the phenotype of activated T cells: two were CD4+, and one was CD8+. All three cells responded to all allogeneic human cell lines tested with enhanced proliferation, production of interleukin 2 (IL-2), and increased expression of the IL-2 receptor. Binding of CD2 to its ligand CD58 was the critical event mediating stimulation because: (a) monoclonal antibodies (mAbs) to CD2 and to CD58, but not to a variety of other surfac…
Herpes virus saimiri-transformed human T lymphocytes: normal functional phenotype and preserved T cell receptor signalling
1993
Herpes virus saimiri (HVS), a primate herpes virus, transforms human CD4+ and CD8+ T lymphocytes to continuous growth in vitro. We have previously shown that HVS-transformed human T cells (HVS-T cells) respond to stimulation via CD2 with autocrine growth. In the present study we have investigated the functional characteristics of HVS-T cells. We describe that these cells can perform all the functions of normal T cells, i.e. cytokine secretion, cytotoxicity, and exocytosis of granule esterases. All these activities can be triggered via CD2 by binding to its natural ligand or via the TCR, e.g. by anti-TCR antibodies, by recognition of a bacterial superantigen and by MHC-restricted recognition…
Il deficit di tipicità delle interdittive antimafia
2020
In 2019, according to the report drawn up by the National Anti-Corruption Authority, they were banned 2044 Italian companies, of which 1458 based in the Southern Regions. An alarming fact which, if on the one hand, would seem acceptable to prevent the infiltration of associations mafia groups in the national economy in the public procurement system and in the loans disbursed by the State; on the other hand, it could reasonably be understood due to the very broad regulatory framework and articulated that characterizes the anti-mafia documentation system. The present work starting from the motivation system of the sentence of 5 September 2019, n. 6105 aims to investigate, first of all, the la…
Phenolic Compounds Characterization and Antioxidant Properties of Monocultivar Olive Oils from Northeast Algeria
2020
In Algeria, the olive tree is one of the main fruit species and plays a very important socioeconomic role. The objective of this study was firstly, to identify and quantify the phenolics of some Algerian olive oils, and secondly, to assess the antioxidant activity of the samples. The olive oils used in this study were derived from Algerian cultivars, including Tefahi, Gelb Elfarroudj, Chemlal, and imported cultivar Manzanilla and Zebboudj. For this purpose, gas chromatography&mdash
Theoretical Determination of the pK a Values of Betalamic Acid Related to the Free Radical Scavenger Capacity: Comparison Between Empirical and Quant…
2015
Health benefits of dietary phytochemicals have been suggested in recent years. Among 1000s of different compounds, Betalains, which occur in vegetables of the Cariophyllalae order (cactus pear fruits and red beet), have been considered because of reducing power and potential to affect redox-modulated cellular processes. The antioxidant power of Betalains is strictly due to the dissociation rate of the acid moieties present in all the molecules of this family of phytochemicals. Experimentally, only the pK a values of betanin were determined. Recently, it was evidenced it was evidenced as the acid dissociation, at different environmental pHs, affects on its electron-donating capacity, and fur…
INTRODUZIONE AL D.LGS. 19 GENNAIO 2017, N. 3, DI ATTUAZIONE DELLA DIR. 2014/104/UE SUL RISARCIMENTO DEI DANNI PER VIOLAZIONE DELLA NORMATIVA ANTITRUST
2018
Con l’emanazione del d.lgs. 19 gennaio 2017, n. 3 e` stata data attuazione alla direttiva 2014/104/UE del Parlamento e del Consiglio del 26 novembre 2014, relativa a determinate norme che regolano le azioni per il risarcimento del danno ai sensi del diritto nazionale per violazioni delle disposizioni del diritto della concorrenza degli Stati membri e dell’Unione europea. Lo scritto, nell'introdurre una serie di commenti alla neo-introdotta normativa, esamina il percorso evolutivo che ha condotto all'emanazione della direttiva, le scelte con essa operate e le modalità di recepimento nell'ordinamento italiano. With the issuance of Legislative Decree January 19, 2017, no. 3 was implemented the…
