DIS-EMBODIED LANGUAGE: L'ACQUISIZIONE LINGUISTICA IN ASSENZA DI RIFERIMENTI ORO-ARTICOLATORI. L'ELOQUIO DEL BAMBINO DISPRASSICO ITALIANO.
La tesi fornisce una prima classificazione sistematica dei fenomeni fonetico-fonologici che caratterizzano l'eloquio del bambino, di lingua italiana, affetto da disprassia verbale in età evolutiva. Presenta, inoltre, un'ipotesi di lettura della patologia dal punto da un punto di vista "embodied" ed ipotesi di ricerca attinenti
Open, laparoscopic, and robotic-assisted hepatectomy in resection of liver tumors : a non-systematic review.
Nas ?ltimas d?cadas, in?meros fatores transformaram as hepatectomias
em opera??es mais seguras. A quimioterapia, juntamente com novas drogas para o tratamento
de met?stases propiciaram melhores respostas, o que possibilitou a indica??o cir?rgica em
pacientes que inicialmente n?o eram candidatos a ela. Les?es hep?ticas muitas vezes requerem
ressec??o, que pode ser realizada tanto por laparotomia, por videolaparoscopia ou assistida
por plataforma rob?tica.Several factors have made hepatectomy an increasingly safe surgery
and new drugs allowed surgical treatment for patients who initially were not candidates for
resection. Lesions often require resection, which can be performed by open, laparoscopic, or
robotic assisted hepatectomy

Identification of Small Molecule Inhibitors of Pseudomonas aeruginosa Exoenzyme S Using a Yeast Phenotypic Screen
Pseudomonas aeruginosa is an opportunistic human pathogen that is a key factor in the mortality of cystic fibrosis patients, and infection represents an increased threat for human health worldwide. Because resistance of Pseudomonas aeruginosa to antibiotics is increasing, new inhibitors of pharmacologically validated targets of this bacterium are needed. Here we demonstrate that a cell-based yeast phenotypic assay, combined with a large-scale inhibitor screen, identified small molecule inhibitors that can suppress the toxicity caused by heterologous expression of selected Pseudomonas aeruginosa ORFs. We identified the first small molecule inhibitor of Exoenzyme S (ExoS), a toxin involved in Type III secretion. We show that this inhibitor, exosin, modulates ExoS ADP-ribosyltransferase activity in vitro, suggesting the inhibition is direct. Moreover, exosin and two of its analogues display a significant protective effect against Pseudomonas infection in vivo. Furthermore, because the assay was performed in yeast, we were able to demonstrate that several yeast homologues of the known human ExoS targets are likely ADP-ribosylated by the toxin. For example, using an in vitro enzymatic assay, we demonstrate that yeast Ras2p is directly modified by ExoS. Lastly, by surveying a collection of yeast deletion mutants, we identified Bmh1p, a yeast homologue of the human FAS, as an ExoS cofactor, revealing that portions of the bacterial toxin mode of action are conserved from yeast to human. Taken together, our integrated cell-based, chemical-genetic approach demonstrates that such screens can augment traditional drug screening approaches and facilitate the discovery of new compounds against a broad range of human pathogens

Benthic estuarine communities in Brazil: moving forward to long term studies to assess climate change impacts
Abstract Estuaries are unique coastal ecosystems that sustain and provide essential ecological services for mankind. Estuarine ecosystems include a variety of habitats with their own sediment-fauna dynamics, all of them globally undergoing alteration or threatened by human activities. Mangrove forests, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress due to human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems on a global scale. The ReBentos network is the first integrated attempt in Brazil to monitor estuarine changes in the long term to detect and assess the effects of global warming. This paper is an initial effort of ReBentos to review current knowledge on benthic estuarine ecology in Brazil. We herein present and synthesize all published work on Brazilian estuaries that has focused on the description of benthic communities and related ecological processes. We then use current data on Brazilian estuaries and present recommendations for future studies to address climate change effects, suggesting trends for possible future research and stressing the need for long-term datasets and international partnerships
