Il volume riporta i risultati della ricerca “Abitudini e stili di vita dei ragazzi e delle ragazze a Palermo”. La ricerca, tenendo sullo sfondo il tema della povertà educativa, si è mossa sostenendo l’ipotesi che analizzando gli stili di consumo culturale e mediale, di fruizione del tempo libero, e altri indicatori specifici, sia possibile fornire una definizione più ampia e complessa di povertà educativa, come molta della più recente letteratura sull’argomento sta peraltro già sostenendo.

BIO/16 - ANATOMIA UMANA ,bortezomib, neurotoxicity, multiple myeloma - Abstract
Bortezomib (BTZ) is a highly effective and widely used antineoplastic drug for the treatment of multiple myeloma. Despite its effectiveness, the use of this proteasome inhibitor is limited by its toxicity and in particular peripheral neurotoxicity is a major and clinically-relevant problem. In fact, since the earliest Phase I and Phase II studies, in a significant proportion of BTZ-treated patients a severe sensory peripheral neuropathy emerged as a dose-limiting side effect. Unfortunately, till now the management of BTZ-peripheral neurotoxicity is an unsolved issue. The use of animal models is one of the most widely used to investigate the neurotoxicity of anticancer drugs, provided they are able to reproduce the clinical use of the drug. Since it has been suggested that bortezomib peripheral neurotoxicity is more severe in myeloma patients that in those affected by solid cancers, the currently available animal models can be less reliable in the attempt to reproduce the clinical use of the drug. Therefore, we developed a myeloma-bearing animal model in which immunodeficient scid mice were intravenously treated with BTZ 1 mg/kg weekly for 5 weeks (q7dx5). Mice were s.c. injected into the right flank with 10x106 cell/0.1 mL/mouse of RPMI-8226 multiple myeloma cells. Treatments started three days after tumor injection.The results of this study evidenced that the administration of BTZ at a dose able to treat experimental myeloma and to induce proteasome activity inhibition comparable to that achieved in myeloma patients induced significant neurophysiological changes vs. vehicle-treated animals in conduction velocity in the caudal and digital nerves and in potential amplitude in the digital nerve. Moreover, the administration of BTZ induced evident pathological changes mostly due to axonopathy vs. vehicle-treated animals in caudal and sciatic nerve as well as in dorsal root ganglia (DRG). Therefore, this model able to mimic the clinical use of BTZ can be reliable and used to test neuroprotective strategies aimed at the reduction of BTZ peripheral neurotoxicity and to rule out their interference with BTZ anti-myeloma activity.

BIO/16 - ANATOMIA UMANA ,Bortezomib, Acetyl-L-Carnitine, Mice model - Abstract
Bortezomib (BTZ) is a highly effective and widely used antineoplastic drug for the treatment of multiple myeloma. Despite its effectiveness, the use of this proteasome inhibitor is limited by its toxicity and in particular peripheral neurotoxicity is a major and clinically-relevant problem and an unsolved issue. The administration of Acetyl-L-Carnitine (ALC) in rat models of different peripheral neuropathies induced by other antineoplastic drugs has evidenced a neuroprotective effect of ALC. To investigate the neuroprotective role of ALC, we used a multiple myeloma-bearing animal model in which scid mice were iv treated with BTZ 1 mg/kg (q7dx5) or ALC 200 mg/kg/daily (qdx5/wx5w) alone or in co-treatment. Mice were s.c. injected into the right flank with 10x106 cell/0.1 mL/mouse of RPMI-8226 multiple myeloma. Treatments started three days after tumor injection. Aim of our study was to evaluate if the co-administration of ALC was able to prevent the peripheral neurotoxicity induced by BTZ chronic treatments. The results of this study evidenced that the administration of BTZ was able to induce significant neurophysiological changes vs. vehicle-treated animals in conduction velocity in the caudal and digital nerves and in potential amplitude in the digital nerve. The same results were observed in nerve conduction velocities in the BTZ+ALC treated mice, while the potential amplitude in the digital nerve was not significantly different from vehicle-treated animals in BTZ+ALC mice. Moreover, the administration of BTZ induced evident pathological changes vs. vehicle-treated animals in the caudal sciatic nerve or dorsal root ganglia (DRG). The same changes were observed in the BTZ+ALC treated mice, although in the caudal nerve an evident trend toward a less severe effect of BTZ administration was present in the animals co-treated with ALC. In conclusion, although not all the parameters investigated in this study evidenced a positive effect, a neuroprotective activity of ALC could be evidenced in the caudal nerve investigated at the pathological level and in the amplitude of the potential measured in the digital nerve

Abitudini e stili di vita ,capabilities ,povertà educativa - Abstract
La ricerca su Abitudini e stili di vita dei ragazzi e delle ragazze a Palermo ha rappresentato un momento di riflessione, di studio e di indagine sul tema della povertà educativa. Partendo dal quadro disegnato dall’indagine desk, l’obiettivo principale dell’indagine field è stato quello di studiare empiricamente il territorio, in modo da individuare con maggiore analiticità i beneficiari ed i contenuti specifici da approfondire. Per tale motivo, la ricerca è stata finalizzata ad approfondire il tema partendo dalle abitudini e gli stili di vita dei ragazzi e delle ragazze frequentanti le terze classi delle scuole secondarie di primo grado del territorio del Comune di Palermo, tenendo nello sfondo il tema della povertà educativa. L’analisi dei concetti che in questa sede viene proposta non ha carattere di esaustività ma ha l’obiettivo di costruire una cornice di riferimento e di offrire spunti per future ri- flessioni. Per tale ragione, per ulteriori approfondimenti, si rimanda alla letteratura specifica sull’argomento. Dal punto di vista metodologico, questa fase d’indagine si è avvalsa di strumenti di rilevazione diretta delle informazioni. La scelta di utilizzare una strategia di ricerca quantitativa ha comportato la formulazione e concettualizzazione dell’oggetto; la progettazione e costruzione della base empirica; il trattamento, l’elaborazione e l’analisi della base empirica

La ricerca su “Abitudini e stili di vita dei ragazzi e delle ragazze a Palermo”, tenendo sullo sfondo il tema della povertà educativa, si è mossa sostenendo l’ipotesi che analizzando gli stili di consumo culturale e mediale, di fruizione del tempo libero, e altri indicatori specifici, sia possibile fornire una definizione più ampia e complessa di povertà educativa, come molta della più recente letteratura sull’argomento sta peraltro già sostenendo . Se, per esempio, definiamo la povertà educativa come «insieme complesso di fattori che generano il mancato o limitato accesso a istruzione e formazione nonché alle opportunità di apprendimento nel corso della vita, al pieno esercizio della cittadinanza e alla fruizione delle occasioni culturali» (Rossi Doria 2017, p. 49), è evidente l’aggancio con una visione di “policentrismo formativo” (Cesareo 1974) che sin dalla fine degli anni ’70 del secolo scorso metteva in discussione il sistema scuola-centrico sino ad allora dominante, affermando che «l’educazione non si può circoscrivere in uno solo o anche in più spazi, poiché al limite ogni “spazio sociale” possiede una propria valenza educativa» (p. 45). In una prospettiva di “comunità educante”, all’educazione formale si affiancano pertanto gli attori e i contesti dell’educazione non formale (l’associazionismo giovanile, i centri di aggregazione giovanile, ecc.) e informale (la famiglia, i media e la Rete, il gruppo dei pari, ecc.), tutti egualmente coinvolti nello sviluppo dell’individuo in un’ottica di educazione permanente. Parafrasando la definizione di Rossi Doria, la tesi qui sostenuta è che un «mancato o limitato accesso» ai media e alla Rete si traduce immediatamente in povertà educativa ovvero in mancato o limitato «esercizio di cittadinanza». Coerentemente con questa impostazione, nel corso della nostra ricerca abbiamo raccolto dati sui consumi mediali e sulle attività online dei ragazzi e delle ragazze di Palermo , con un focus sul digital parenting, ovvero sul ruolo dei genitori.

Il testo analizza i dati sulla povertà educativa a Palermo, suddividendoli per Circoscrizione e, quando possibile, per quartiere. Ne esce fuori un quadro complesso e variegato, che mostra come le differenze territoriali siano profondamente marcate. Il testo utilizza i dati rilevati tramite un questionario organizzato da un gruppo di ricerca che comprende l'autore; inoltre, al testo sono allegate diverse mappe tematiche che esemplificano visivamente le differenze territoriali. The text analyses the data on educational poverty in Palermo, subdividing them by Circoscrizioni and, when possible, by neighbourhood. The result is a complex and varied picture that shows how the territorial differences are profoundly marked. The text uses the data collected through a questionnaire organised by a research group that includes the author; moreover, several thematic maps are attached to the text and visually exemplify the territorial differences.

Nel distinguere tra aree tradizionali e non tradizionali dell’espansione mafiosa si suole indicare come nel primo caso il potere delle mafie si configuri innanzitutto come un dominio di tipo politico-militare che si avvale di quella estesa rete relazionale, altrimenti definita sotto l’accezione di capitale sociale. Nel secondo caso, la caratteristica prevalente della mafia è quella di una pervasiva penetrazione e diffusione all’interno del tessuto economico-produttivo. Questa tipologia finisce spesso per corroborare la tesi del contagio. Al momento in cui le mafie penetrano – con i loro capitali, i loro traffici illegali e la loro organizzazione militare – all’interno della cosiddetta “parte sana” del paese, si verificherebbe la meridionalizzazione del Nord. In altre parole, le mafie recherebbero con sé la diffusione del malaffare anche in contesti territoriali fino ad allora considerati avulsi da queste logiche. Ad uno sguardo analitico più accurato, il contesto dei rapporti tra le logiche del degrado di origine mafiosa e le aree non tradizionali si presenta in modo ben più articolato. In primo luogo, va sottolineato non soltanto il fatto che i capitali mafiosi creino un beneficio rilevante all’economia settentrionale, ma anche che non potrebbero penetrarne il tessuto produttivo senza avvalersi dei terminali locali situati negli interstizi dell’economia e della politica locale. In secondo luogo, le mafie trapiantate al Nord diventano più efficienti, più vischiose, più camaleontiche perché, per attecchire e proliferare nel tessuto settentrionale, devono introiettarne la dinamicità tipica delle economie contemporanee. Lo scopo di questo contributo è quello di mettere in evidenza, a partire dal caso Sindona fino ad arrivare alle più recenti inchieste giudiziarie sulla ‘ndrangheta, che non ci troviamo di fronte ad una permeabilità e impreparazione dell’economia settentrionale di fronte all’attacco delle mafie, bensì di fronte ad un processo osmotico che, a partire dalle cointeressenze che si formano tra mondi legali e illegali nelle sfere della politica e dell’economia, sfocia in uno scambio di valori, di reti e di modelli di comportamento. Di conseguenza, non è di meridionalizzazione o di settentrionalizzazione che bisogna parlare, ma di una porosità dei confini tra legalità e illegalità che investe tutto il paese nel suo complesso.

Foreigners are a very important resource for Italy not only for the evolution of the Italian society (through for example the contribution they provide to the natural balance, with a fertility rate about twice that of Italian) but also for their important role in our labor market (see Istat, 2009). But when we want to measure the dimension of phenomenon and, through it, to determine significance levels of foreign presence in the territory, there is enormous difficulties in the collection of information. In this job to solve this problem we consider small area estimation methods. We use the continuous labor force survey conducted by ISTAT for the year 2008. Then to choose the best model we consider a simulation through the Monte Carlo method. Results obtained are very interesting.

- Abstract
Ruthenium catalyzed 1,3-cycloaddition (click chemistry) of an azido moiety installed on dihydroxycumene scaffold with differently substituted aryl propiolates gave a new family of 1,4,5-trisubstituted triazole carboxylic acid derivatives that showed high affinity toward Hsp90 associated with cell proliferation inhibition, both in nanomolar range. The 1,5 arrangement of the resorcinol, the aryl moieties, and the presence of an alkyl (secondary) amide in position 4 of the triazole ring were essential to get high activity. Docking simulations suggested that the triazoles penetrate the Hsp90 ATP binding site. Some 1,4,5-trisubstituted triazole carboxamides induced dramatic depletion of the examined client proteins and a very strong increase in the expression levels of the chaperone Hsp70. In vitro metabolic stability and in vivo preliminary studies on selected compounds have shown promising results comparable to the potent Hsp90 inhibitor NVP-AUY922. One of them, (compound 18, SST0287CL1) was selected for further investigation as the most promising drug candidate.

- Abstract
Adarotene belongs to the so-called class of atypical retinoids. The presence of the phenolic hydroxyl group on Adarotene structure allows a rapid O-glucuronidation as a major mechanism of elimination of the drug, favoring a fast excretion of its glucuronide metabolite in the urines. A series of ether, carbamate and ester derivatives was synthesized. All of them were studied and evaluated for their stability at different pH. The cytotoxic activity in vitro on NCI-H460 non-small cell lung carcinoma and A2780 ovarian tumor cell lines was also tested. A potential back-up of Adarotene has been selected to be evaluated in tumor models., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

- Abstract
A structural investigation on the isoxazole scaffold led to the discovery of 3,4-isoxazolediamide compounds endowed with potent Hsp90 inhibitory properties. We have found that compounds possessing a nitrogen atom directly attached to the C-4 heterocycle ring possess in vitro Hsp90 inhibitory properties at least comparable to those of the structurally related 4,5-diarylisoxazole derivatives. A group of compounds from this series of diamides combine potent binding affinity and cell growth inhibitory activity in both series of alkyl- and aryl- or heteroarylamides, with IC50 in the low nanomolar range. The 3,4-isoxazolediamides were also very effective in causing dramatic depletion of the examined client proteins and, as expected for the Hsp90 inhibitors, always induced a very strong increase in the expression levels of the chaperone Hsp70. In vivo studies against human epidermoid carcinoma A431 showed an antitumor effect of morpholine derivative 73 comparable to that induced by the reference compound 10.

- Abstract
Purpose: Acetyl-L-carnitine (ALC) plays a relevant role in energy metabolism and stress response because of its function in the complex metabolic system regulating the acetyl-CoA levels that provide a source of acetyl groups for metabolic and acetylation-regulated processes. Because acetylation may influence p53 activity/stability and, therefore, the response to platinum compounds, this study was designed to investigate the effect of ALC in combination with platinum compounds., Experimental Design: The antiproliferative and antitumor activity studies were done in a panel of human tumor cell lines with functional or defective p53. The antimetastatic drug efficacy was investigated in the s.c. growing H460/M tumor subline, which is able to generate lung metastases., Results: ALC enhanced the sensitivity to cisplatin of tumor cells with functional p53. The sensitization by ALC was reflected in an improved in vivo antitumor efficacy of the combination over cisplatin alone in wild-type p53 lung tumors. ALC did not increase the cisplatin efficacy in the p53-mutant SW620 tumor. ALC exhibited a significant antimetastatic activity, and this effect was better exploited in combination with the histone deacetylase inhibitor, ST3595. The in vivo ALC/cisplatin combination caused the activation of p53, associated with protein acetylation and induction of target genes., Conclusions: ALC was effective in enhancing the antitumor potential of platinum compounds in wild-type p53 tumors. ALC, alone and in combination with a histone deacetylase inhibitor, exhibited an outstanding antimetastatic activity. Both effects, likely mediated by protein acetylation, may have implications for platinum-based therapy and combinations with histone deacetylase inhibitors., ((c) 2010 AACR.)

- Abstract
Five RGD peptide-camptothecin (CPT) conjugates were designed and synthesized with the purpose to improve the therapeutic index of this antitumoral drug family. New RGD cyclopeptides were selected on the basis of their high affinity to alpha(v) integrin receptors overexpressed by tumor cells and their metabolic stability. The conjugates can be divided in two groups: in the first the peptide was attached to the drug through an amide bond, in the second through a hydrazone bond. The main difference between the two spacers lies in their acid stability. Affinity to the receptors was maintained for all conjugates and their internalization into tumor cells was demonstrated. The first group conjugates showed lower in vitro and in vivo activity than the parent drug, probably due to the excessive stability of the amide bond, even inside the tumor cells. Conversely, the hydrazone conjugates exhibited in vitro tumor cell inhibition similar to the parent drug, indicating high conversion in the culture medium and/or inside the cells, but their poor solubility hampered in vivo experiments. On the basis of these results, information was acquired for additional development of derivatives with different linkers and better solubility for in vivo evaluation., (Copyright (c) 2009 Elsevier Ltd.

- Abstract
ST1968 is a novel hydrophilic camptothecin (CPT) derivative of the 7-oxyiminomethyl series. Because ST1968 retained ability to form remarkably stable cleavable complexes, this study was done to investigate its preclinical profile of antitumor activity in a large panel of human tumor models, including irinotecan-resistant tumors. Although less potent than SN38 in vitro, i.v. administered ST1968 caused a marked tumor inhibition, superior to that of irinotecan, in most tested models. ST1968 exhibited an impressive activity against several tumors including models of ovarian and colon carcinoma in which a high rate of cures was observed. In the most responsive tumors, complete and persistent tumor regressions were achieved even with low suboptimal doses. Even tumors derived from intrinsically resistant cells exhibited a significant responsiveness. Histologic analysis of treated tumors supports a contribution of both proapoptotic and antiangiogenic effects to ST1968 antitumor efficacy. A study done in yeast cells transformed with CPT-resistant mutant forms of topoisomerase I documented that, in contrast to other tested CPT, ST1968 was active against yeasts expressing the mutant K720E enzyme. Based on its outstanding efficacy superior to that of irinotecan and of its good therapeutic index, ST1968 has been selected for clinical development.

- Abstract
ST1968, a novel hydrophilic camptothecin analogue of the 7-oxyiminomethyl series, is characterised by the formation of stable DNA-topoisomerase I cleavable complex and by a promising profile of antitumour activity. The present study was designed to extend preclinical evaluation of the novel camptothecin in human squamous cell carcinoma (SCC) models. ST1968 exhibited an impressive activity with a high cure rate in SCC models. ST1968 produced 100% of complete response without evidence of regrowth in tumours characterised by susceptibility to drug-induced apoptosis (FaDu, A431 and A2780). In contrast to irinotecan, ST1968 still showed an excellent, persisting activity in models less susceptible to apoptosis induction (KB, Caski and SiHa), in which drug treatment elicited a persistent DNA damage response, as documented by phosphorylation of p53, RPA-2 and histone H2AX, resulting in delayed apoptosis and senescence. This behaviour was associated with a marked cellular/tumour drug accumulation. In conclusion, ST1968 exhibited an outstanding antitumour activity superior to that of irinotecan against SCC. A high intracellular accumulation, resulting in fast apoptosis or DNA damage persistence, appeared to be a critical determinant of SCC sensitivity to ST1968.

- Abstract
Using the circular dichroism spectra induced in the visible by the binding to the minor groove of DNA, we found that Hoechst 33258 is able to occupy its specific sites even when these are located inside the nucleosome structure. This high accessibility of the DNA in the nucleosome is not modified by the removal of the amino-terminal domains of the octamer histones and is not reduced by the presence of linker histone. Interesting and reasonable differences were found in the association constants.

- Abstract
Using the circular dichroism spectra, induced in the visible range by the binding of minor groove ligands to DNA, we found that two drugs, DAPI and Hoechst 33258, are able to occupy their specific sites even when these are located inside the nucleosome structure. This high accessibility of the binding sites in the nucleosome is not modified by the removal of the amino-terminal domains of the octamer histones and, surprisingly, it is not reduced by the presence of linker histone. Interesting and reasonable differences were found in the association constants, that reveal the "reluctance" of the ligands to bind the DNA-minor groove when the histones are present.
