Attività citotossica dei celomociti di Holothuria tubulosa (Echinodermata)

2010

Numerosi studi hanno accertato che nel fluido celomatico degli echinodermi sono presenti cellule con attività diretta verso agenti estranei. In particolare i celomociti svolgono un repertorio di funzioni immunitarie tra cui la fagocitosi, la citotossicità, l’attività antibatterica, la formazione di capsule e il rigetto dei trapianti. Nel presente lavoro abbiamo studiato l’attività citotossica dei celomociti di Holothuria tubulosa (Oloturoideo) non separati ed abbiamo utilizzato cellule di mammifero come target. I celomociti prelevati dal fluido celomatico lisano gli eritrociti di coniglio o di montone e le cellule tumorali della linea eritromieloide umana K562. Inoltre anche il supernatante…

Complications of hepatic echinococcosis: multimodality imaging approach

2019

AbstractHydatid disease is a worldwide zoonosis endemic in many countries. Liver echinococcosis accounts for 60–75% of cases and may be responsible for a wide spectrum of complications in about one third of patients. Some of these complications are potentially life-threatening and require prompt diagnosis and urgent intervention. In this article, we present our experience with common and uncommon complications of hepatic hydatid cysts which include rupture, bacterial superinfection, and mass effect-related complications. Specifically, the aim of this review is to provide key imaging features and diagnostic clues to guide the imaging diagnosis using a multimodality imaging approach, includin…

Biodiversity of Antarctic echinoids: a comprehensive and interactive database

2005

Eighty-one echinoid species are present south of the Antarctic Convergence, and they represent an important component of the benthic fauna. “Antarctic echinoids” is an interactive database synthesising the results of more than 100 years of Antarctic expeditions, and comprising information about all echinoid species. It includes illustrated keys for determination of the species, and information about their morphology and ecology (text, illustrations and glossary) and their distribution (maps and histograms of bathymetrical distribution); the sources of the information (bibliography, collections and expeditions) are also provided. All these data (taxonomic, morphologic, geographic, bathymetri…

La traducción del folleto turístico: el trasvase léxico del español al chino

2017

Esta tesis doctoral presenta como objetivo principal analizar el trasvase terminológico del español al chino en el sector turístico a partir de la descripción de los mecanismos más empleados, así como de las dificultades que surgen a lo largo de su aplicación en diferentes subcampos nocionales del turismo. Este objetivo se plantea especialmente a partir de dos factores: el aumento de turistas chinos en España y de la intensificación de actividades turísticas bilaterales, con la consiguiente necesidad de traducción de los discursos del sector; y la escasa bibliografía sobre la traducción turística español-chino, en particular, vinculada a su vertiente terminológica. Desde una perspectiva teó…

Unità e diversità nella marcatura differenziale dell'oggetto diretto in rumeno e in siciliano Studio Comparativo

Questa ricerca si propone di analizzare il fenomeno della marcatura differenziale dell'oggetto (d'ora in avanti MDO - Bossong 1985) descrivendone caratteristiche, funzioni, somiglianze e differenze: nel siciliano, e i suoi dialetti e nel romeno. La tesi mira a realizzare uno studio comparativo, essenzialmente esplicativo di un fenomeno presente in molte lingue (secondo Bossong più di 300) e che ancora oggi continua a essere oggetto di numerosi studi, per lo più tipologici (Bossong 1985, 1991, Comrie 1989, Croft 1988, Aissen 2003, Iemmolo 2010). La MDO, nota anche come accusativo preposizionale nella linguistica romanza (Niculescu 1959, 1965, Rohlfs 1984), è una variazione nella codifica deg…

Data from: Quality attracts parasites: host condition-dependent chemo-orientation of trematode larvae

2014

1. Environmental factors impairing physiological condition of organisms are assumed to predispose them to parasite infections. This is because host immune function is typically condition-dependent. However, poor physiological condition has been reported to reduce host susceptibility to parasites in various systems. 2. We examined whether such an effect can be due to altered exposure of hosts to active parasite transmission stages by investigating chemo-orientation of free-swimming cercariae larvae of a parasite Echinoparyphium aconiatum towards its snail host Lymnaea stagnalis. 3. We used both long-term and short-term feeding treatments to manipulate the body condition and physiological tra…

Data from: Empirical and theoretical study of Atelostomate (Echinoidea, Echinodermata) plate architecture: using graph analysis to reveal structural …

2015

Describing patterns of connectivity among organs is essential for identifying anatomical homologies among taxa. It is also critical for revealing morphogenetic processes and the associated constraints that control the morphological diversification of clades. This is particularly relevant for studies of organisms with skeletons made of discrete elements such as arthropods, vertebrates, and echinoderms. Nonetheless, relatively few studies devoted to morphological disparity have considered connectivity patterns as a level of morphological organization or developed comparative frameworks with proper tools. Here, we analyze connectivity patterns among apical plates in Atelostomata, the most dive…

Economic evaluation of caspofungin vs liposomal amphotericin B for empirical therapy of suspected systemic fungal infection in the German hospital se…

2007

As antifungal agents are frequently used in hematology and oncology, economic data on the empirical therapy of suspected systemic fungal infection are pivotal. Data were analyzed according to: (1) the rate of nephrotoxicity related to treatment with caspofungin in comparison to liposomal amphotericin B (L-AmB) from a randomized clinical trial, (2) the effect of nephrotoxicity on length of hospital stay from a European observational study, and (3) an example of total bottom-up cost in a department of hematology in Germany. All estimates include 95% confidence intervals (CI) using two-stage Monte Carlo simulation on binominal and Gaussian random variables from separate studies with comparable…

Multiple pulmonary and multivesicular interatrial septum hydatid cysts in a native italian patient

2008

Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation. A rare case of multivesicular interatrial septum hydatid cyst with multiple pulmonary involvement in a native Italian farm labourer is reported. Clinical, radiological, serological and histological findings are described. MR imaging showed the exact anatomic location and the multivesicular nature of the cardiac cyst and was useful in planning surgical treatment. A successful outcome was achieved with a combination of…

Hydatidosis of the Central Nervous System in South America

2014

In this chapter, we reviewed the epidemiology of cystic hydatidosis in South America, especially focusing on hydatidosis of the central nervous system. Echinococcus granulosus and E. multilocularis are the most frequent species in humans. Hydatidosis is endemic in several Latin American countries, including Argentina, Bolivia, Brazil, Chile, Peru, and Uruguay. The global occurrence of hydatid cysts of the central nervous system is uniformly low, with a reported incidence of 0.9–2.1 % of all cases of hydatidosis.
