L’espressione “apprendimento naturale” indica una liaison difficile: i due componenti del sintagma fanno riferimento a modalità glottodidattiche contrapposte, quella implicita e informale dell’acquisizione naturale e quella esplicita e formale dell’apprendimento di una L2. Essa non esprime la volontà di mettere in dubbio l’approccio naturale nell’apprendimento, ma propone di recuperare alcune modalità di conoscenza linguistica implicita proprie dell’acquisizione della L1 nella didattica della L2, estendendole, quantitativamente e qualitativamente, in modo che risultino rispettose della globalità e della sistematicità dell’acquisizione di conoscenze da parte della persona apprendente .

Determination of Glyphosate and AMPA in Food Samples Using Membrane Extraction Technique for Analytes Preconcentration
2021
The method for determining glyphosate (NPG) and its metabolite AMPA (aminomethyl phosphonic acid) in solid food samples using UAE-SLM-HPLC–PDA technique was developed. Firstly, ultrasonic-assisted solvent extraction (UAE) and protein precipitation step were used for the analyte isolation. Then, the supernatant was evaporated to dryness and redissolved in distilled water (100 mL). The obtained solution was alkalized to pH 11 (with 1 M NaOH) and used directly as donor phase in SLM (supported liquid membrane) extraction. The SLM extraction was performed using 2 M NaCl (5 mL) as an acceptor phase. The flow rate of both phases (donor and acceptor) was set at 0.2 mL/min. The membrane extraction t…

Vitom® 3D in arterio-venous fistulas: Single centre preliminary surgical experience
2021
Background: Arteriovenous fistula (AVF) is the vascular access of choice for hemodialysis patients. A correct microsurgical vascular anastomoses is essential to the optimal care of patients. Loupes can help surgeons perform such procedures, but often cause neck or back pain and fatigue. Aim: This study aimed to evaluate whether a video telescopic operating microscope (VITOM®; Karl Storz Endoscopy GmbH, Tuttlingen, Germany) could be used as a substitute for loupes to create microsurgical vascular anastomoses. Methods: We evaluated microsurgical anastomoses with VITOM® in 10 patients (6 male, 4 female) from January 2019 to December 2019. The created anastomoses were 7 side-to-side, 2 side-to-…
Modeling cost-effectiveness and health gains of a âuniversalâ versus âprioritizedâ hepatitis C virus treatment policy in a real-life cohort
2017
We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virusâinfected patients: policy 1, âuniversal,â treat all patients, regardless of fibrosis stage; policy 2, treat only âprioritizedâ patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virusâinfected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were us…
Simple two-step synthesis of 2,4-disubstituted pyrroles and 3,5-disubstituted pyrrole-2-carbonitriles from enones
2014
The cyclocondensation of enones with aminoacetonitrile furnishes 3,4-dihydro-2H-pyrrole-2-carbonitriles which can be readily converted to 2,4-disubstituted pyrroles by microwave-induced dehydrocyanation. Alternatively, oxidation of the intermediates produces 3,5-disubstituted pyrrole-2-carbonitriles.
Dysfunctional High-Density Lipoproteins Are Associated With a Greater Incidence of Acute Coronary Syndrome in a Population at High Cardiovascular Risk
2020
Background: Studies have failed to establish a clear link between high-density lipoprotein (HDL) cholesterol and cardiovascular disease, leading to the hypothesis that the atheroprotective role of HDL lies in its biological activity rather than in its cholesterol content. However, to date, the association between HDL functional characteristics and acute coronary syndrome has not been investigated comprehensively. Methods: We conducted a case-control study nested within the PREDIMED (Prevención con Dieta Mediterránea) cohort, originally a randomized trial in which participants followed a Mediterranean or low-fat diet. Incident acute coronary syndrome cases (N=167) were individually matched …
Adopción en casos especiales y unidad del status filiationis en el derecho italiano: ¿cómo repercute en el plano sucesorio?
2022
In the Italian legal system, there has recently been recognition by the Constitutional Court in adoptions in particular cases of the existence of civil relations between the adoptee and the relatives of the adopter, thus equalizing the margins of protection of minors, regardless of the situations of fact or law from which the new status of the child originated. This jurisprudential work is full of considerable systematic reflections and is intended to be applied not only to the hypothesis of adoption by same-sex couples, but also to all those cases in which a state of semi-permanent abandonment or cyclical abandonment occurs. Notwithstanding the negative value directed at the forms of surro…
Practices in research, surveillance and control of neglected tropical diseases by One Health approaches: A survey targeting scientists from French-sp…
2021
One health (OH) approaches have increasingly been used in the last decade in the fight against zoonotic neglected tropical diseases (NTDs). However, descriptions of such collaborations between the human, animal and environmental health sectors are still limited for French-speaking tropical countries. The objective of the current survey was to explore the diversity of OH experiences applied to research, surveillance and control of NTDs by scientists from French-speaking countries, and discuss their constraints and benefits. Six zoonotic NTDs were targeted: echinococcoses, trypanosomiases, leishmaniases, rabies, Taenia solium cysticercosis and leptospiroses. Invitations to fill in an online q…
