Analisi LCA delle case di paglia di Pescomaggiore (AQ)

Questa tesi di laurea ha un duplice scopo: da un lato l’analisi delle caratteristiche delle balle di paglia usate come materiale da costruzione, dall’altro la valutazione ambientale tramite metodologia LCA di un intervento di reinsediamento post-sisma a Pescomaggiore, in Abruzzo, realizzato con edifici in balle di paglia autocostruiti. Nella parte prima si focalizza l’attenzione sulle direttive europee e i loro recepimenti italiani a cui fare riferimento per le gestione energetica degli edifici, oltre ad una panoramica sulla certificazione energetica. Si riportano inoltre sinteticamente quelle parti della normativa edilizia che riguardano le costruzioni con materiali innovativi. La parte seconda è il frutto di una lunga fase di ricerca bibliografica, in cui si è cercato di fare chiarezza sulle caratteristiche della paglia: traspirabilità, isolamento termico, resistenza al fuoco e fonoassorbenza le parti su cui si è maggiormente rivolta l’attenzione. Nella parte terza viene descritta dettagliatamente la metodologia LCA, e in particolare la sua applicazione nel campo dell’edilizia: le diverse fasi in cui si compone, l’uso di software e di banche dati appropriate e i metodi più utilizzati per l’analisi degli impatti. Nella quarta ed ultima parte viene descritto dettagliatamente il caso di studio: una delle case di paglia dell’Ecovillaggio di Pescomaggiore; segue una descrizione accurata della fase di inventario, effettuata anche tramite un sopralluogo in sito. Infine vengono riportati e commentati i risultati dell’analisi, ed espresse considerazioni e proposte migliorative.

ROLE OF MIR-19A RELEASED BY INFLAMMATORY BREAST CANCER CELLS IN THE REGULATION OF DENDRITIC CELL FUNCTIONS: IN VITRO MODEL OF CROSSTALK IN THE TUMOR MICROENVIRONMENT OF INFLAMMATORY BREAST CANCER

Inflammatory breast cancer (IBC) is a rare but very aggressive form of locally advanced breast cancer (1-6% of total breast cancer patients in United States), with a 5-year overall survival rate of only 40.5%, compared with 85% of the non-IBC patients. So far, a unique molecular signature for IBC able to explain the dramatic differences in the tumor biology between IBC and non-IBC has not been identified. As immune cells in the tumor microenvironment plays an important role in regulating tumor progression, we hypothesized that tumor-associated dendritic cells (TADC) may be responsible for regulating the development of the aggressive characteristics of IBC. MiRNAs can be released into the extracellular space and mediate the intercellular communication by regulating target gene expression beyond their cells of origin. We hypothesized that miRNAs released by IBC cells can induce an increased activation status, secretion of pro-inflammatory cytokines and migration ability of TADC. In an in vitro model of IBC tumor microenvironment, we found that the co-cultured of the IBC cell line SUM-149 with immature dendritic cells (iDCSUM-149) induced a higher degree of activation and maturation of iDCSUM-149 upon stimulation with lipopolysaccharide (LPS) compared with iDCs co-cultured with the non-IBC cell line SUM-159 (iDCSUM-159), resulting in: increased expression of the costimulatory and activation markers; higher production of pro-inflammatory cytokines (TNF-a, IL-6); and 3) higher migratory ability. These differences were due to the exosome-mediated transfer of miR-19a and miR-146a from SUM-149 and SUM-159, respectively, to iDCs, causing the downregulation of the miR-19a target genes PTEN, SOCS-1 and the miR-146a target genes IRAK1, TRAF6. PTEN, SOCS-1 and IRAK1, TRAF6 are important negative and positive regulator of cytokine- and TLR-mediated activation/maturation signaling pathway in DCs. Increased levels of IL-6 induced the upregulation of miR-19a synthesis in SUM-149 cells that was associated with the induction of CD44+CD24-ALDH1+ cancer stem cells (CSCs) with epithelial-to-mesenchymal transition (EMT) characteristics. In conclusion, in IBC tumor microenvironment IL-6/miR-19a axis can represent a self-sustaining loop able to maintain a pro-inflammatory status of DCs, leading to the development of tumor cells with high metastatic potential (EMT CSCs) responsible of the poor prognosis in IBC patients.
