L'utilizzabilità degli atti nella fase investigativa. La prova per le indagini preliminari

The doctorate’s theme of research - Abstract My doctorate’s theme of research is about the Investigation in the Italian criminal proceedings. The Italian Code of criminal procedure of 1988 is the fruit of a new ideology that marks a departure from Italy’s prior inquisitorial tradition. According to criminal procedure Code of 1988, an accusatorial system separates the investigation and trial stages and the judge’s decision is based only on evidence collected in oral form in his presence in a public trial containing adversarial dynamics. The Italian Code of 1988 created a separation between criminal investigations and trial. Investigations are conducted by Public Prosecutor: he conducts the investigation phase in order to deem whether to file a formal charge against the defendant or to dismiss the case and the investigative evidence collected should serve only for this purpose. According to so called “inutilizzabilità fisiologica”’s rule, the evidence collected during investigations by prosecutor is not usable during trial by the judge: the results of the investigative efforts displayed by the parties should be kept outside of court. If the proceedings go on to trial, the case shall be deemed with only evidence collected in front of the judge. To create the separation of the trial phase from the investigation stage, there is the double-dossier system. During the investigations, evidence are collected in an investigation dossier. The trial judge will never see the investigation dossier and the trial judge’s decision is based on a new dossier, the trial dossier, with the evidence collected during the trial. The issue of my research is about the investigation, the so called “inutilizzabilità fisiologica”’s rule and also the exclusionary rules that concern the investigative phase and the decisions pronounced during the investigations (for example, the decisions concerning pre-trial confinement). 2 In fact, the exclusionary rule system (so called “inutilizzabilità patologica”) provides that evidence cannot be used in Italian criminal proceedings if it was the result of illegal inquiry.

Validazione e applicazioni cliniche della metodica NIRA (Near Infrared Reflectance Analysis) per la valutazione del contenuto nutrizionale del latte materno in terapia intensiva neonatale

Phase 1: To validate Near-Infrared Reflectance Analysis (NIRA) as a fast, reliable and suitable method for routine evaluation of human milk’s nitrogen and fat content. Phase 2: To determine whether fat content, protein content and osmolality of HM before and after fortification may affect gastroesophageal reflux (GER) in symptomatic preterm infants. Patients and Methods: Phase 1: 124 samples of expressed human milk (55 from preterm mothers and 69 from term mothers) were used to validate NIRA against traditional methods (Gerber method for fat and Kjeldhal method for nitrogen). Phase 2: GER was evaluated in 17 symptomatic preterm newborns fed naïve and fortified HM by combined pH/intraluminal-impedance monitoring (pH-MII). HM fat and protein content was analysed by a Near-Infrared-Reflectance-Analysis (NIRA). HM osmolality was tested before and after fortification. GER indexes measured before and after fortification were compared, and were also related with HM fat and protein content and osmolality before and after fortification. Results: Phase 1: · A strong agreement was found between traditional methods’ and NIRA’s results (expressed as g/100 g of milk), both for fat and nitrogen content in term (mean fat content: NIRA=2.76; Gerber=2.76; mean nitrogen content: NIRA=1.88; Kjeldhal =1.92) and preterm (mean fat content: NIRA=3.56; Kjeldhal=3.52; mean nitrogen content: NIRA=1.91; Kjeldhal =1.89) mother’s milk. · Nitrogen content of the milk samples, measured by NIRA, ranged from 1.18 to 2.71 g/100 g of milk in preterm milk and from 1.48 to 2.47 in term milk; fat content ranged from 1.27 to 6.23 g/100 g of milk in preterm milk and from 1.01 to 6.01 g/100 g of milk in term milk. Phase 2: · An inverse correlation was found between naïve HM protein content and acid reflux index (RIpH: p=0.041, rho=-0.501). · After fortification, osmolality often exceeded the values recommended for infant feeds; furthermore, a statistically significant (p<.05) increase in non acid reflux indexes was observed. Conclusions: NIRA can be used as a fast, reliable and suitable tool for routine monitoring of macronutrient content of human milk. Protein content of naïve HM may influence acid GER in preterm infants. A standard fortification of HM may worsen non acid GER indexes and, due to the extreme variability in HM composition, may overcome both recommended protein intake and HM osmolality. Thus, an individualized fortification, based on the analysis of the composition of naïve HM, could optimize both nutrient intake and feeding tolerance.

Studio immunologico per l'individuazione di pazienti trapiantati per cirrosi HBV relata che potrebbero sospedere la terapia con immunoglobine specifiche (HBIG)

Hepatitis B virus (HBV) recurrence after orthotopic liver transplantation (OLT) is associated with poor graft and patient survival. Treatment with HBV-specific immunoglobulins (HBIG) in combination with nucleos(t)ide analogs is effective in preventing HBV reinfection of the graft and improving OLT outcome. However, the combined immunoprophylaxis has several limitations, mainly the high cost and the lack of standard schedules about duration. So far, the identification of markers able to predict the reinfection risk is needed. Although the HBV-specific immune response is believed to play an essential role in disease outcome, HBV-specific cellular immunity in viral containment in OLT recipients is unclear. To test whether or not OLT recipients maintain robust HBV-specific cellular immunity, the cellular immune response against viral nucleocapsid and envelope-protein of HBV was assessed in 15 OLT recipients and 27 individuals with chronic and 24 subjects with self-limited HBV infection, respectively. The data demonstrate that OLT recipients mounted fewer but stronger clusters of differentiation (CD)8 T cell responses than subjects with self-limited HBV infection and showed a preferential targeting of the nucleocapsid antigen. This focused response pattern was similar to responses seen in chronically infected subjects with undetectable viremia, but significantly different from patients who presented with elevated HBV viremia and who mounted mainly immune responses against the envelope protein. In conclusion, virus-specific CD4 T cell–mediated responses were only detected in subjects with self-limited HBV infection. Thus, the profile of the cellular immunity against HBV was in immune suppressed patients similar to subjects with chronic HBV infection with suppressed HBV-DNA.

La musa bambina. 1911-2011: un secolo di letteratura mitologica per ragazzi in Italia tra storia, educazione e narrazione

Questa ricerca mostra l’evoluzione della letteratura mitologica per ragazzi in Italia. Il primo libro italiano di mitologia per bambini è stato pubblicato nel 1911 (lo stesso anno di un’importante e violenta guerra coloniale tra l’Italia e la Libia): la scrittrice italiana Laura Orvieto pubblicò allora “Storie della storia del mondo”, in cui riunì antichi racconti greci per giovani lettori. Queste storie erano ispirate al libro mitologico per bambini “Il libro delle meraviglie” di Hawthorne (titolo originale “A Wonder Book for Girls and Boys”). In seguito molti scrittori italiani scrissero libri mitologici per giovani lettori: serie importanti di libri di mitologia per bambini furono pubblicate durante il regime mussoliniano – talvolta per diffondere l’ideologia fascista della superiorità romana. Durante questo periodo, i libri mitologici spesso mostravano uno stile letterario solenne. Dopo la seconda guerra mondiale, la letteratura mitologica per bambini cambiò lentamente prospettiva: gli scrittori italiani cominciarono ad usare il mito per parlare di problemi sociali (p.e. Gianni Rodari descriveva re Mida come un capitalista) e per spiegare le diverse condizioni umane (p.e. Beatrice Masini fa riferimento alle dee e alle eroine greche per descrivere la condizione femminile). La ricerca analizza anche la relazione tra mito e scuola in Italia: i racconti mitologici hanno sempre fatto parte dei programmi scolastici italiani per bambini dagli 8 agli 11 anni. Le riforme scolastiche – deliberate negli anni ’20 e ’40 – fissarono pratiche didattiche sui miti ancora oggi in uso. I racconti mitologici erano soprattutto un supporto per gli studi storici e letterari. Tuttavia, negli ultimi decenni, i miti sono divenuti un importante aiuto per gli insegnamenti scientifici e artistici.
