Microbial tool to improve salt tolerance in plants

Soil salinization, caused by enhanced concentrations of different salts in soils, usually is a consequence of anthropic activity. Saline soils induce stressful conditions to plants, thus leading to growth reduction and physiological dysfunctions, such as overproduction of reactive oxygen species (ROS), reduction photosynthetic activity and osmotic imbalance. Several attempts have been tried to improve salt tolerance in different crops. Among them, seed priming and Plant Growth Promoting Bacte...

Investigation of Pseudomonas aeruginosa responses to zinc starvation reveals the existence of a pyochelin Zurregulated transport system

Previous studies have suggested that P. aeruginosa possesses redundant zinc uptake systems. In addition to the already characterized metal transport systems, genome wide expression studies have revealed other possible contributors to zinc uptake. The main goal of this study was to investigate the role of two uncharacterized Zur-regulated operons encoding putative metal import systems: PA4063-4065 and PA2911-2914. A structural characterization of the protein encoded by the PA4063 gene has show...

From the mainland to sea and back: plastic’s path in demersal communities exploited by fishing

L'inquinamento da rifiuti nei fondali marini è emerso come un problema ambientale significativo, che pone potenziali minacce alla biodiversità marina e al funzionamento dell'ecosistema. I fondali marini sono un habitat fondamentale per numerose specie marine e l'accumulo di rifiuti altera l'equilibrio e la funzione essenziale di questo sistema ecologico. Questo inquinamento può influenzare gli organismi sia a livello individuale, attraverso l'ingestione o l'impigliamento, sia a livello di com...

Clinical implications of periprocedural myocardial injury in patients undergoing percutaneous coronary intervention for chronic total occlusion: role of antegrade and retrograde crossing techniques

Clinical Implications of Periprocedural Myocardial Injury in Patients Undergoing Percutaneous Coronary Intervention for Chronic Total Occlusion: Role of Antegrade and Retrograde Crossing Techniques. Aims: Periprocedural myocardial injury (PMI) is frequently observed after percutaneous coronary interventions (PCI) for chronic total occlusion (CTO). We investigated the prognostic impact of PMI with the antegrade or the retrograde crossing technique. Methods and Results: A total of 1’909 pati...

Il diritto alla privacy, la protezione dei dati personali: modelli normativi a confronto

Nel presente lavoro, ci si propone di esaminare l’evoluzione del concetto di riservatezza, partendo da una prospettiva storica, filosofica e sociologica, per poi approfondire la sua trasformazione nel diritto dell’Unione Europea, nei sistemi di civil law e common law, e infine in alcuni Paesi specifici. Il Capitolo I si addentra nelle radici storiche e filosofiche del concetto di privacy, iniziando dall’antica Roma, dove la riservatezza emergeva come un valore fondamentale nell’ordinamento gi...

Characterization of HIV-1 genetic variability in newly HIV-1 diagnosed patients: role in influencing immunological and viral response, including reservoir burden

miR-126 modulates the PI3K/Akt pathway in breast cancer cells

Dysregulation of miRNA expression profiles occurs in several human malignancies and, depending on mRNAs targeted by the specific miRNA, they can exert either promoting or suppressive effects on cancer cells. We have previously shown that physiological delivery of platelet miR-126 induces cellular effects in breast cancer cells, including cell cycle arrest, inhibition of migration and sensitivity to cisplatin. Here, we went further insight by investigating potential miR-126 molecular targets. ...
