Abstract:
Eukaryotic cells release the phylogenetically ancient protein acyl coenzyme A binding protein (ACBP, which in humans is encoded by the gene DBI, diazepam binding inhibitor) upon nutrient deprivation. Accordingly, mice that are starved for one to two days and humans that undergo voluntary fasting for one to three weeks manifest an increase in the plasma concentration of ACBP/DBI. Paradoxically, ACBP/DBI levels also increase in obese mice and humans. Since ACBP/DBI stimulates appetite, this latter finding may explain why obesity constitutes a self-perpetuating state. Here, we present a theoretical framework to embed these findings in the mechanisms of weight control, as well as a bioinformatics analysis showing that, irrespective of the human cell or tissue type, one single isoform of ACBP/DBI (ACBP1) is preponderant (~90% of all DBI transcripts, with the sole exception of the testis, where it is ~70%). Based on our knowledge, we conclude that ACBP1 is subjected to a biphasic transcriptional and post-transcriptional regulation, explaining why obesity and fasting both are associated with increased circulating ACBP1 protein levels.

Abstract:
Peripheral benzodiazepine (BDZ) receptor (PBR) and diazepam-binding inhibitor/acyl-CoA-binding protein (DBI/ACBP) characterized as a ligand at central BDZ receptors, at PBR with involvement in the regulation of steroidogenesis, and as an intracellular acyl-CoA transporter, are both known to interact with BDZ in adult systems. We investigated their expression after prenatal exposure to BDZ. Diazepam (1.25 mg/kg per day s.c.) was administered to time-pregnant Long Evans rats from gestational day (GD) 14 to 20. Expression of mRNAs encoding for PBR and for DBI/ACBP was studied in the same animals with (33)P-labeled 60 mer oligonucleotides (oligos) by in situ hybridization at GD20, and with (32)P-labeled oligos by Northern blot in steroidogenic and immune organs at postnatal day (PN) 14 and in adult offspring. Prenatal diazepam increased DBI/ACBP mRNA expression in male fetal adrenal and in fetal and PN14 testis. Thymus exhibited increased DBI/ACBP mRNA in male fetuses and in adult female offspring, and reduced organ weight at PN14 in both sexes. In female spleen, an increase in DBI/ACBP mRNA and a decrease in PBR mRNA was seen at PN14. Apart from the finding in spleen, no drug-induced changes in PBR mRNA were observed. The effects of prenatal diazepam were superimposed on treatment-independent sex differences in DBI/ACBP mRNA and PBR mRNA expression. Our data indicate that expression of DBI/ACBP mRNA in steroidogenic and immune organs can be affected by exposure to BDZ during ontogeny, while PBR mRNA expression appears to be less sensitive. They further reveal marked sex differences in the developmental patterns of the two proteins during pre- and postpubertal ontogeny.

Eur J Endocrinol 1994;131:201–4. ISSN 0804–4643 Diazepam-binding inhibitor (DBI) has been localized immunohistochemically in many organs. In porcine and rat pancreas, DBI is present in non-B-cells of the pancreatic islets. Porcine peptide also has been shown to suppress insulin secretion from rat pancreas in vitro. Recently, acyl-CoA-binding protein (ACBP) was isolated from rat liver and shown to be identical structurally to DBI isolated from rat brain. Using this rat DBI/ACBP, we have studied its effects on glucose-stimulated insulin secretion in the rat, both in vivo and in isolated pancreatic islets. Infusion iv of rDBI/ACBP (25 pmol/min) during glucose stimulation induced a moderate and transient reduction of plasma insulin levels. Moreover, rDBI/ACBP suppressed insulin release from batch-incubated isolated islets, stimulated by 16.7 mmol/l glucose, by 24% at 10 nmol/l (p < 0.05) and by 40% at 100 nmol/l (p < 0.01). The peptide (100 nmol/l) also inhibited the insulin response to glucose (16.7 mmol/l) from perifused rat islets by 31% (p < 0.05), mainly by affecting the acute-phase response. Finally, incubation of isolated islets in the presence of rDBI/ACBP antiserum (diluted 1:100 and 1:300) augmented the insulin response to 16.7 mmol/l glucose (p < 0.05 or even less). We conclude that rDBI/ACBP, administered iv or added to the incubation media, suppresses insulin secretion in the rat but that the effect is moderate despite the high concentration used. It is therefore unlikely that the peptide modulates islet hormone release, acting as a classical hormone via the circulation. However, the occurrence of DBI/ACBP in the islets and the enhancing effect by the rDBI/ACBP antibodies on glucose-stimulated insulin release suggest that the peptide is a local modulator of insulin secretion.

Abstract:
Astrocytes via their foot processes (ACfp) are specialized connecting cells, and they structurally connect the neurovascular unit (NVU) mural cells to neurons. Astrocytes provide homeostatic mechanisms for structural connections and provide communication between the NVU and regional neurons for functional hyperemia in regions of increased neuronal activity (neurovascular coupling). Previously, our group has demonstrated a detachment, separation, and retraction of ACfp in diabetic db/db females (DBC). It was hypothesized that a loss of adherent ACfp/NVU could result in the known impaired cognition in DBC. Additionally hypothesized was that empagliflozin treatment could protect DBC ACfp/NVU remodeling. This study demonstrates a significant loss of ACfp/NVU numbers in DBC and a protection of this loss by empagliflozin treatment (DBE). The number of intact ACfp/NVU was 6.45 ± 1.1 in control heterozygous (CKC) vs. 1.88 ± 0.72 in DBC (p < 0.05) and 5.86 ± 0.88 in DBE vs. DBC (p < 0.05) by visually hand-counting the capillary NVUs (22 in CKC, 25 in DBC, and 22 in DBE). These findings suggest that empagliflozin provides neuroprotection via the prevention of ACfp separation in DBE as compared to diabetic DBC. Furthermore, a loss of ACfp/NVU numbers in DBC may correspond with a negative modulation of informational processing, and the protection of ACfp/NVU numbers could provide a protective modulation in DBE models.

Abstract:
AbstractThis paper focuses on evolving an absorptive capacity (ACAP) assessment tool designed to help firms understand their ACAP maturity in processing external knowledge. ACAP maturity is evaluated based on a firm's capacity and willingness to do relevant ACAP practices. Although an earlier version of the ACAP tool was able to evaluate maturity and highlight immature practice, it could not determine how critical these practices were for improvement action. Thus, a means of eliciting the importance of practices and aggregating it with their ACAP maturity evaluations is needed. This paper provides summaries of the subjective weight elicitation methods and aggregation techniques which were identified from the domain of multi-criteria decision making. Criteria for comparing these methods are defined and analyzed to determine the most appropriate methods for the current application. The SRF method for subjective weight elicitation, aggregated with the maturity evaluations through weight sum models, is deemed the most appropriate for the current application. During testing with users, the SRF procedure was found to suffer from various usability concerns which will be investigated in future work.

Abstract:
La protéine se liant aux acyl-coenzymes A (ACBP), aussi appelée inhibiteur de liaison du diazépam (DBI), est une protéine ubiquitaire et fortement conservée au sein des organismes eucaryotes. Chez les mammifères, elle joue un rôle double : l'ACBP intracellulaire se lie aux acides gras activés (acyl-coA) et, lorsqu'elle est sécrétée, ACBP joue le rôle d'une hormone régulatrice du métabolisme et de l'obésité. L'analyse de données publiques démontre une tendance à l'augmentation d'ACBP dans de nombreuses pathologies caractérisées par un dérèglement systémique : c'est le cas, entre autres, chez les patients atteints de stéatose hépatique, de formes graves du VIH ou du COVID-19 et de certains cancers. Enfin, les concentrations d'ACBP dans le plasma sont positivement corrélées avec l'âge des individus. Il a récemment été démontré chez la souris que la modulation des niveaux d'ACBP circulant permettait de contrôler les paramètres métaboliques des animaux. L'obésité et le syndrome métabolique étant parmi les premiers facteurs de risque environnementaux pour le développement des maladies liées au vieillissement, comme les maladies cardiovasculaires et le cancer, nous nous sommes intéressés dans ces travaux à déterminer si ces maladies pouvaient être annoncées par une élévation des niveaux d'ACBP circulants. L'analyse de cohortes d'individus déclarés en bonne santé a révélé une augmentation d'ACBP dans le cas de la survenue prochaine d'événements cardiovasculaire ou de cancer. L'utilité d'ACBP ensuite été explorée dans plusieurs contextes précliniques. D'une part, la neutralisation de cette protéine étend la durée de vie des levures et est protectrice du vieillissement accéléré du cœur chez la souris, causé par les anthracyclines (une classe de chimiothérapies couramment utilisée et connue pour ses effets cardiotoxiques). Dans le cadre du cancer, la modulation de ce checkpoint métabolique a un impact positif sur l'immunosurveillance tumorale et améliore la réponse aux traitements par chimio-immunothérapie chez la souris. Ainsi, notre étude révèle qu'ACBP pourrait être un biomarqueur de l'« âge biologique » des patients, son élévation annonçant la survenue imminente de maladies liées à l'âge. Au-delà de sa valeur prédictive, les premiers essais précliniques démontrent que sa neutralisation est une piste prometteuse pour améliorer la santé métabolique des individus, qui peut être exploitée pour prévenir ou améliorer la réponse aux traitements des maladies cardiovasculaires et du cancer
Acyl-coenzyme A binding protein (ACBP), also known as diazepam binding inhibitor (DBI), is a ubiquitous and highly conserved protein in eukaryota. In mammals, it plays a dual role: intracellular ACBP binds to activated fatty acids (acyl-CoAs) and, when secreted, ACBP acts as a peptide hormone regulating metabolism and obesity. The analysis of publicly available datasets demonstrates a tendency for increased ACBP in physio-pathological contexts, such as hepatic steatosis, severe forms of HIV or COVID-19, and certain cancers. Additionally, plasma ACBP concentrations are positively correlated with chronological age.Recent studies in mice have shown that modulation of circulating ACBP levels can also control metabolic parameters in animals. Obesity and metabolic syndrome are among the primary environmental risk factors for the development of age-related diseases, such as cardiovascular diseases and cancer, therefore our research aimed to determine if these diseases could be preceded by a modification in circulating ACBP levels.In cohorts of apparently healthy of individuals, we detected an elevation of ACBP in patients who would imminently develop cardiovascular events or cancer. The utility of this aging biomarker was further explored in different preclinical contexts. On one hand, neutralization of the protein extends the lifespan of yeast and, in mice, it protects against accelerated aging of the heart caused by anthracyclines (a class of chemotherapies commonly used and known for their cardiotoxic effects). In the context of cancer, modulation of this metabolic checkpoint has a positive impact on tumor immunosurveillance and improves the response to chemotherapy-immunotherapy treatments in mice. Thus, our study reveals that ACBP could be a biomarker of patients' "biological age,", with its elevation indicating the imminent onset of age-related diseases. Beyond its predictive value, initial preclinical trials demonstrate that neutralization of ACBP is a promising option for improving metabolic health in patients, which could be exploited to prevent or enhance the response to treatments for cardiovascular diseases and cancer

Abstract:
Vibrio harveyi myristoyl-ACP thioesterase (LuxD) differs from most thioesterases in substrate specificity, turnover rate and rate limiting step with the deacylation step occurring at a very slow rate. A serine residue, Ser114, which is the central serine in the sequence A-x-S-x-S and not part of the standard G-x-S-x-G consensus motif, has been identified as the active site nucleophile. Ser114 together with His241 and Asp211, form a catalytic triad with a mechanism similar to that of the esterase/lipase family. Tryptophan fluorescence of the V. harveyi thioesterase and its tryptophan mutants showed that there is a ligand induced conformational change during acylation of the enzyme and that the fluorescence of tryptophan 213 is specifically enhanced on substrate binding. A chimeric LuxD, constructed from Photobacterium phosphoreum LuxD and Vibrio harveyi LuxD was shown to be hyperactive compared to its parental LuxDs. Studies of this chimera revealed that the carboxyl-terminal half of the thioesterase is the part of the molecule involved with interaction with the synthetase component of the fatty acid reductase complex responsible for synthesis of aldehyde substrate for the luminescent reaction.

Abstract:
L'Imagerie par Résonance Magnétique pondérée en Diffusion (IRM-D) permet l'accès à l'information structurelle des tissus au travers de la lecture du mouvement brownien des molécules d'eau. Ses applications sont nombreuses en imagerie cérébrale, tant en milieu clinique qu'en recherche. Néanmoins le mouvement physiologique créé une perte de signal supplémentaire au cours de l'encodage de la diffusion. Cette perte de signal liée au mouvement limite les applications de l'IRM-D quant à l'imagerie cardiaque. L'utilisation de faibles valeurs de pondération (b) réduit cette sensibilité mais permet seulement l'imagerie du mouvement incohérent intra-voxel (IVIM) qui contient la circulation sanguine et la diffusion des molécules d'eau. L'imagerie IVIM possède pourtant de nombreuses applications en IRM de l'abdomen, depuis la caractérisation tissulaire à la quantification de la perfusion, mais reste inexplorée pour l'imagerie du coeur. Mon travail de thèse correspond à l'évaluation des conditions d'application de l'IRM-D à faibles valeurs de b pour le coeur humain, afin de proposer des contributions méthodologiques et d'appliquer les techniques développées expérimentalement. Nous avons identifié le mouvement cardiaque comme une des sources majeures de perte de signal. Bien que le mouvement global puisse être corrigé par un recalage non-rigide, la perte de signal induite par le mouvement perdure et empêche l'analyse précise par IRM-D du myocarde. L'étude de cette perte de signal chez un volontaire a fourni une fenêtre temporelle durable où le mouvement cardiaque est au minimum en diastole. Au sein de cette fenêtre optimale, la fluctuation de l'intensité atteste d'un mouvement variable résiduel. Une solution de répéter les acquisitions avec un déclenchement décalé dans le temps permet la capture des minimas du mouvement, c.-à-d. des maximas d'intensité en IRM-D. La projection du maximum d'intensité dans le temps (TMIP) permet ensuite de récupérer des images pondérées en diffusion avec un minimum de perte de signal lié au mouvement. Nous avons développé et évalué différentes séquences d'acquisition combinées avec TMIP : la séquence d'imagerie écho-planaire classique par écho de spin (SE-EPI) peut être adaptée mais souffre du repliement d'image ; une séquence Carr-Purcell-Meiboom-Gill combinée avec une préparation d'encodage de diffusion est plus robuste aux distorsions spatiales mais des artefacts de bandes noires empêchent son applicabilité ; finalement une séquence double-SE-EPI compensant les courants de Foucault et pleinement optimisée produit des images IRM-D moins artefactées. Avec cette séquence, l'IRM-D-TMIP permet la réduction significative de la perte de signal liée au mouvement pour l'imagerie cardiaque pondérée en diffusion. L'inconvénient avec TMIP vient de l'amplification du bruit positif d'intensité. Afin de compenser cette sensibilité du TMIP, nous séparons le bruit d'intensité des fluctuations lentes liées au mouvement grâce à une nouvelle approche basée sur l'analyse en composantes principales (PCA). La décomposition préserve les détails anatomiques tout en augmentant les rapports signal et contraste-à-bruit (SNR, CNR). Avec l'IRM-D-PCATMIP, nous augmentons à la fois l'intensité finale et la qualité d'image (SNR) en théorie et expérimentalement. Les bénéfices ont été quantifiés en simulation avant d'être validés sur des volontaires. De plus la technique a montré des résultats reproductibles sur des patients post-infarctus aigue du myocarde, avec un contraste cohérent avec la position et l'étendue de la zone pathologique. Contrairement à l'imagerie cérébrale, l'imagerie IRM-D par faibles valeurs de pondération in vivo doit être différentiée des analyses IRM-D ex-vivo. Ainsi l'IRM-D-PCATMIP offre une technique sans injection pour l'exploration du myocarde par imagerie IVIM. Les premiers résultats sont encourageants pour envisager l'application sur un modèle expérimental d'une maladie cardiovasculaire [etc...]
Diffusion weighted magnetic resonance imaging (DW-MRI, or DWI) enables the access to the structural information of body tissues through the reading of water molecules Brownian motion. Its applications are many in brain imaging, from clinical practice to research. However physiological motion induces an additional signal-loss when diffusion encoding is applied. This motion-induced signal-loss limits greatly its applications in cardiac imaging. Using low diffusion-weighting values (b) DWI reduces this sensitivity but permits only the imaging of intravoxel incoherent motion (IVIM), which combines both water diffusion and perfusion. IVIM imaging has many applications in body MRI, from tissue characterization to perfusion quantification but remains unexplored for the imaging of the heart. The purpose of this work was to evaluate the context of low b-values DWI imaging of the heart, propose methodological contributions and then apply the developed techniques experimentally. We identified cardiac motion as one of the major sources of motion-induced signal loss. Although bulk motion can be corrected with a non-rigid registration algorithm, additional signal-loss remains uncorrected for and prevents accurate DWI of the myocardium. The study of diffusion-weighted signal-loss induced by cardiac motion in a volunteer provided a time-window when motion is at minimum in diastole. Within this optimal time-window, fluctuation of intensity attests of variable remaining physiological motion. A solution to repeat acquisition with shifted trigger-times ease the capture of motion amplitude minima, i.e. DWI-intensity maxima. Temporal maximum intensity projection (TMIP) finally retrieves diffusion weighted images of minimal motion-induced signal-loss. We evaluated various attempts of sequence development with TMIP: usual spin-echo echo-planar imaging (se-EPI) sequence can be improved but suffers aliasing issues; a balanced steady-state free-precession (b-SSFP) combined with a diffusion preparation is more robust to spatial distortions but typical banding artifacts prevent its applicability; finally a state-of-the-art double-spin-echo EPI sequence produces less artifacted DWI results. With this sequence, TMIP-DWI proves to significantly reduce motion-induced signal-loss in the imaging of the myocardium. The drawback with TMIP comes from noise spikes that can easily be highlighted. To compensate for TMIP noise sensitivity, we separated noise spikes from smooth fluctuation of intensity using a novel approach based on localized principal component analysis (PCA). The decomposition was made so as to preserve anatomical features while increasing signal and contrast to noise ratios (SNR, CNR). With PCATMIP-DWI, both signal-intensity and SNR are increased theoretically and experimentally. Benefits were quantified in a simulation before being validated in volunteers. Additionally the technique showed reproducible results in a sample of acute myocardial infarction (AMI) patients, with a contrast matching the extent and location of the injured area. Contrarily to brain imaging, in vivo low b-values DWI should be differentiated from ex vivo DWI pure diffusion measurements. Thus PCATMIP-DWI might provide an injection-free technique for exploring cardiac IVIM imaging. Early results encourage the exploration of PCATMIP-DWI in an experimental model of cardiac diseases. Moreover the access to higher b values would permit the study of the full IVIM model for the human heart that retrieves and separates both perfusion and diffusion information

Laboratory, semi-field and field experiments were conducted with the aim of identifying biological and integrated control strategies to be applied against Frankliniella occidentalis. We studied the spatial and temporal distribution of the main thrips pests in greenhouses and potential antagonists in some greenhouses characterized by a different level of lateral openings and a rose garden in the open. The second experiment was planned to show that opening greenhouse structures are not automatically related to an increase in thrips problems on ornamental crops. The third experimental study has been undertaken with the aim of evaluating the impact of some biological control agents (BCAs) on Frankliniella occidentalis population. In the fourth experiment, the effect of a fungal strain of Beauveria bassiana on F. occidentalis reached the highest levels when residual and topical exposures were combined

Abstract:
Unique among the intracellular lipid binding proteins, acyl CoA binding protein (ACBP) exclusively binds long chain fatty acyl CoAs (LCFA-CoAs). To test if ACBP is an essential protein in mammals, the ACBP gene was ablated by homologous recombination in mice. While ACBP heterozygotes appeared phenotypically normal, intercrossing of the heterozygotes did not result in any live homozygous deficient (null) ACBP^(-/-) pups. Heterozygous and wild type embryos were detected at all postimplantation stages, but no homozygous ACBP null embryos were obtained– suggesting that an embryonic lethality occurred at a preimplantation stage of development, or that embryos never formed. While ACBP null embryos were not detected at any blastocyst stage, ACBP null embryos were detected at the morula (8- cell), cleavage (2-cell), and zygote (1-cell) preimplantation stages. Two other LCFACoA binding proteins, sterol carrier protein-2 (SCP-2) and sterol carrier protein-x (SCPx) were significantly upregulated at these stages. These findings demonstrate for the first time that ACBP is an essential protein required for embryonic development and its loss of function may be initially compensated by concomitant upregulation of two other LCFA-CoA binding proteins only at the earliest preimplantation stages. The fact that ACBP is the first known intracellular lipid binding protein whose deletion results in embryonic lethality suggests its vital importance in mammals.

Abstract:
L’immigrazione dalla nascita degli Stati-nazione e dall’imposizione delle frontiere, non è solo una questione di movimenti della popolazione, è un meccanismo complesso in cui intervengono gli Stati riceventi, le politiche di categorizzazione, le politiche di immigrazione, quelle di asilo, la gestione delle frontiere esterne (Commissione Europea, 2019), le reazioni delle società nei confronti nuovi arrivati, i Paesi di origine e gli stessi migranti (Ambrosini, 2011). Il percorso appena delucidato prende il nome di National-Building Process (Zanfrini, 2016, 7) frutto delle scelte politiche-istituzionali di ogni Paese che ne definisce le peculiarità ideologiche. Tutti gli Stati, europei e non, ad oggi, adottano una politica di contrasto delle frontiere in ragione della crescente domanda di mobilità; questa situazione ha portato alla nascita di un’economia di frontiera che ha generato meccanismi di sbarchi illegali, falsificazione dei documenti, attraversamenti marittimi, matrimoni combinati ed ingressi nei Paesi con visti turistici utilizzati con l’intento di poter sfuggire poi alla legge. Tutti questi meccanismi aumentano la complessità del fenomeno. In letteratura sono stati presi in analisi diversi fattori per studiare i flussi migratori, primo fra tutti il fattore economico (Bertolini, Pistoresi, Zaghi, 2006, 30) sulla base di studi principalmente econometrici, a seguire, il mercato del lavoro, la relazione tra i Paesi, il ricongiungimento e la regolazione politica (Commissione Europea, 2019). La regolazione politica delle migrazioni non sembra essere un fattore di spinta con il quale spiegare il fenomeno migratorio (assimilabile principalmente ai fattori di tipo economico), ma al contrario sembra essere un fattore di attrazione verso uno o l’altro Paese. Il fattore politico, secondo Ambrosini, spiega le modalità delle migrazioni, l’orientamento verso un Paese apparentemente più accessibile ma non la scelta stessa di partire. Ma cosa spinge invece un Paese ad adottare un tipo di politica migratoria piuttosto che un’altra? Quali sono i principali fattori che influenzano tale scelta? E che ruolo ricoprono i flussi in questa scelta politica? Ciò che nella letteratura risulta essere ancora incerto sono appunto questo tipo di considerazioni. Cercare una risposta è difficile perché bisogna tenere conto che la spiegazione delle migrazioni non può prendere in considerazione nessuno dei fattori appena descritti in maniera esclusiva, necessità di un approccio multi-causale, di un disegno che tenga conto della complessità del fenomeno, dove si intrecciano diversi fattori che possono a sua volta assumere importanza diversa rispetto ai diversi periodi economico-storico-politici di un Paese. Attraverso la costruzione di un disegno longitudinale comparato (Biolcati-Rinaldi, Vezzoni 2012; Caputo, Felaco, Punziano, 2017) che permette di prendere in considerazione più contesti (Paesi UE) e più punti nel tempo [T0: 2008 (Post crisi economica; Trattato europeo sull’immigrazione); T1: 2013 (5 anni dalla prima rilevazione; post primavera araba e pre crisi migratoria); T2: 2018 (5 anni dalla seconda rilevazione; post crisi migratoria e implementazione Agenda Europea del maggio 2015)] l’obiettivo principale della ricerca è di capire quale fattore, tra quelli demografici, economici, politico-culturali e sociali influenzano o meno la scelta dei Paesi UE nell’adottare un tipo di politica migratoria tendente all’apertura o alla chiusura. Nello specifico, si vogliono studiare le connessioni e le correlazioni tra la dimensione legislativa che i Paesi UE adottano e le dimensioni sopradescritte sino ad individuare quali e quanto tali fattori influenzano il tipo di politica migratorie europea. La costruzione del modello è successiva alla ricostruzione delle principali teorie della sociologia delle migrazioni, dei modelli sociologici di spiegazione di queste, delle leggi e dei trattati stipulati dall’Unione Europea negli anni. Tenendo conto delle implementazioni legislative sulle migrazioni da parte dell’Unione Europea si è deciso di focalizzarsi sull’Agenda europea sulle migrazioni (2015) che ad oggi rispecchia la politica globale dell’Unione nel campo preso in analisi e quindi di osservare come si sono comportati i Paesi sull’implementazione delle politiche migratorie prima e dopo l’intervento legislativo europeo.
