Exploring the Chemoselectivity towards Cysteine Arylation by Cyclometallated Au III Compounds: New Mechanistic Insights
2020
To gain more insight into the factors controlling the efficient cysteine arylation by cyclometalated Au(III) complexes, the reaction between selected gold compounds and different peptides was investigated by high‐resolution liquid chromatography electrospray ionization mass spectrometry (HR‐LC‐ESI‐MS). The deducted mechanisms of C–S cross‐coupling, also supported by density functional theory (DFT) and quantum mechanics/molecular mechanics (QM/MM) calculations, evidenced the key role of secondary peptidic gold binding sites in favouring the process of reductive elimination.
Measles in Italy: Viral strains and crossing borders
2019
In 2017, Italy experienced one of the largest outbreaks of measles in recent years, with 5404 notified cases and 4347 confirmed cases. A further 2029 cases were notified during the first 6 months of 2018, and 1516 of them were laboratory-confirmed. The B3 and D8 genotypes were identified as those responsible for the outbreak. Possible transmission routes can be established by monitoring the circulating measles virus strains in support of the national health authorities to warn people and travellers.

Oleoylethanolamide restores alcohol-induced inhibition of neuronal proliferation and microglial activity in striatum
2019
Previous findings demonstrate a homeostatic role for oleoylethanolamide (OEA) signaling in the ethanol-related neuroinflammation and behavior. However, extensive research is still required in order to unveil the effects of OEA on a number of neurobiological functions such as adult neurogenesis, cell survival and resident neuroimmunity that become notably altered by alcohol. Daily consumption of ethanol (10%) for 2 weeks (6.3& #x202F;± 1.1 g/kg/day during last 5 days) caused hypolocomotor activity in rats. This effect appears to rely on central signaling mechanisms given that alcohol increased the OEA levels, the gene expression of OEA-synthesizing enzyme Nape-pld and the number of PPARα-imm…
Impact of COVID-19 on global HCV elimination efforts.
2021
Background & Aims COVID-19 has placed significant strain on national healthcare systems at a critical moment in the context of hepatitis elimination. Mathematical models can be used to evaluate the possible impact of programmatic delays on hepatitis disease burden. The objective of this analysis was to evaluate the incremental change in hepatitis C liver-related deaths and liver cancer, following a 3-month, 6-month, or 1-year hiatus in hepatitis elimination program progress. Methods Previously developed models were adapted for 110 countries to include a status quo or “no delay” scenario and a “1-year delay” scenario assuming significant disruption in interventions (screening, diagnosis and …
Guidelines Have a Key Role in Driving HCV Elimination by Advocating for Simple HCV Care Pathways.
2021
The availability of pangenotypic direct-acting antivirals for treatment of hepatitis C (HCV) has provided an opportunity to simplify patient pathways. Recent clinical practice guidelines have recognised the need for simplification to ensure that elimination of HCV as a public health concern remains a priority. Despite the move towards simplified treatment algorithms, there remains some complexity in the recommendations for the management of genotype 3 patients with compensated cirrhosis. In an era where additional clinical trial data are not anticipated, clinical guidance should consider experience gained in real-world settings. Although more experience is required for some pangenotypic the…
La patria potestad prorrogada y la patria potestad rehabilitada en el nuevo proyecto de ley de reforma de la legislación civil y procesal para el apo…
2021
It is intended to analyze and reflect in the present work about the institution of the extension of parental authority and parental authority rehabilitated in the new regulation in the Draft Law that reforms the civil and procedural legislation to support people with disabilities in the exercise of their legal capacity. In this project, the extended parental authority and the rehabilitated parental authority are eliminated from the scope of disability, following a criterion that demands the treatment of people with disabilities with the attention that their specific situation requires, eliminating a regime that seems contrary to the system of promoting the autonomy of adults with disabiliti…
The impact of direct acting antivirals on hepatitis C virus disease burden and associated costs in four European countries
2021
Eliminació del VHC; Punt d'equilibri; Infecció d'hepatitis C Eliminación del VHC; Punto de equilibrio; Infección de hepatitis C HCV elimination; Break-even; Hepatitis C infection Background and Aims We assessed the clinical and economic impact of direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) in England, Italy, Romania and Spain. Methods An HCV progression Markov model was developed considering DAA eligibility and population data during the years 2015-2019. The period of time to recover the investment in DAAs was calculated as the cost saved by avoiding estimated clinical events for 1000 standardized treated patients. A delayed treatment scenario because of coronavirus di…
Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo
2021
Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…
Characterization of measles virus strains circulating in Southern Italy (Palermo area, Sicily) between 2010 and 2011
2015
Measles virus (MV) was classified in 24 genotypes that show a distinct geographic distribution. Genotypes contain multiple distinct lineages. In 2011 large outbreaks of measles occurred in Italy and in many European countries. Aims of this study are to analyze the intra-genotype variability and to follow the importation and the spread of new MV strains in Sicily. A fragment of 450. bps of MV C-terminal nucleoprotein was sequenced from sera of 73 Sicilian patients with symptomatic measles infections, occurred between 2010 and 2011. Five MV strains were D4 genotype and 68 were D8 genotype. The MV/D4 sequences were related to MV/D4-Enfield variant. Two lineages of MV/D8 genotypes, related to M…
Tailored screening and dedicated funding for direct acting antiviral drugs: How to keep Italy on the road to hepatitis C virus elimination?
2020
Background and aims. Hepatitis C virus (HCV) elimination for Italy is an ambitious, but achievable goal. In Italy, there is political will, which aims to achieve the World Health Organization (WHO) elimination goals recognizing the need to identify undiagnosed individuals in key high-risk groups and in the general population, however there is concern regarding HCV treatment implementation in Italian Regions. Methods. A modelling analysis was conducted, using the “Italy Polaris” model, to forecast the impact of different HCV treatment rates in achieving the HCV elimination goals in Italy. The model assessed two treatment scenarios: 2018 Scenario and 2019 Scenario, using the annually HCV trea…
