Role of filamentation in the pathogenesis of Candidiasis

The ability to undergo the yeast-to-hypha transition is believed to be a key virulence factor of Candida albicans. Hyphae facilitate active penetration of host cells, host cell damage, and escape from immune cells. In addition, C. albicans mutants locked in the yeast morphology have been shown to be avirulent or attenuated in systemic infections further emphasizing the importance of hyphae for virulence. C. albicans mutants lacking the EED1 gene or its expression are able to initiate germ tube formation, but fail to elongate these into hypha and eventually switch back to yeast cell growth. Despite being attenuated in damaging epithelial cells and macrophages in vitro and in virulence in an intraperitoneal infection model in vivo, surprisingly, the eed1∆/∆ mutant was as virulent as the wild type in systemic candidiasis. The retained virulence of mutants lacking EED1 or its expression was accompanied by rapid yeast replication within internal organs, especially in the kidney, the main target organ of systemic candidiasis. Whereas the renal pro-inflammatory cytokine response was delayed early after infection, increased cytokine production was observed at later time points, likely as the result of the increased immune cell infiltration, suggesting a contribution of immunopathology to pathogenesis. This work shows that rapid proliferation is likely the consequence of enhanced metabolic adaptation and increased fitness, as the eed1Δ/Δ mutant shows better growth in kidney homogenates and on certain physiologically relevant carbon sources in vitro. High kidney yeast burden resulted in kidney damage and systemic inflammation comparable to wild type infections. Therefore, rapid proliferation by metabolic adaptation and increased fitness, resulting in high organ yeast burden, can compensate for the loss of filament formation in C. albicans

La Produzione della ceramica a Pantelleria e la sua circolazione in età tardo antica

This research concerning the cooking pottery production in late roman time in the Island of Pantelleria, located in the Sicily Channel.This coarse ware consisted in pans, pots, casseroles and lids and large jars, useful to cook food and other raw materials as bitumen and pitch. This high refractoriness is given to the ceramic mixture by the vulcanic minerals peculiars form the clay of the island. The archaeological excavations conducted until now, discovered a large settlement in the Scauri Bay placed in the S-W coast of the island, datable from the second half of the IV to the end of the V century. The village based its economical activity on the cooking pottery production and its export, as evidenced by the shipwreck in the harbor of Scauri. The pottery materials found in the site and in the shipwreck, come from reliable contexts and it has been helpful to a thorough tipological and chronological study of this local ware production. The analysis of the attestations in the Central and Western Mediterranean, through the bibliography and some unpublished datas from Sicily, led to create some circulation maps across the centuries. This has allowed me to make some considerations and conclusions. It has been possible to realize a diachronic study, to distinguish forms and types from the III cent. B.C. to the V cent. A.D.. The pottery had a wide circulation in the Mediterranean, mostly from the second half of the IV to the beginning of the VI century

Optimisation de production de bioéthanol à partir d’hydrolysats de matière lignocellulosiques, de l’échelle laboratoire à la plateforme pilote

La Chaire de Recherche Industrielle en Éthanol Cellulosique de l’Université de Sherbrooke (CRIEC) et ses partenaires industriels ont établi une collaboration dans le but de développer un procédé de production de bioéthanol à partir d’hydrolysats de matière lignocellulosique. Le présent projet de recherche porte précisément sur l’optimisation de la fermentation alcoolique d’hydrolysats cellulosiques et hémicellulosiques provenant de biomasse mixte, de l’échelle laboratoire à la plateforme pilote. Ce projet s’inscrit dans la vague mondiale de recherche en biocarburants de 2e génération. En effet, à l’heure où la baisse de la dépendance au pétrole est devenue un réel enjeu pour tous, le bioéthanol s’est taillé une place de choix comme carburant alternatif. Le bioéthanol de 2e génération est produit à partir de matières lignocellulosique, provenant de résidus ou de cultures n’entrant pas en compétition pas avec les ressources de l’agriculture vivrière. Renversant ainsi le paradigme du bioéthanol-grain de 1ère génération. Les défis de la production d’éthanol lignocellulosique sont que les microorganismes fermentaires traditionnels ne peuvent pas fermenter les pentoses tels que le xylose (2e sucre en importance dans la matière lignocellulosique) et que les procédés d’hydrolyses chimiques utilisés pour la saccharification de la lignocellulose engendrent des inhibiteurs pouvant diminuer les rendements de ces biocatalyseurs. Vu les larges débouchés économiques, sans oublier les gains environnementaux et sociaux, la communauté scientifique travaille, depuis les années 90, à produire entre autres de nouveaux biocatalyseurs pouvant efficacement faire la conversion lignocellulose-à-éthanol. Tout l’arsenal du génie génétique a été exploité afin de créer une nouvelle souche recombinante pouvant satisfaire aux exigences d’un procédé industriel. À ce jour, il existe plusieurs groupes de recherche ayant développé leur souche de levure ou bactérie génétiquement modifiée, potentiellement capable de répondre à ces exigences. Ce rapport présente les résultats, conclusions et recommandations du projet de recherche. En utilisant une souche de levure génétiquement modifiée pour la co-fermentation du xylose et du glucose, et des hydrolysats lignocellulosiques fournis par les partenaires industriels du CRIEC, il a été possible d’investiguer les performances et les paramètres de fermentation afin de pouvoir démontrer la preuve de concept d’un procédé de production d’éthanol lignocellulosique. Ce projet de recherche se divise donc en 2 phases : 1) une optimisation des performances de fermentation du biocatalyseur à l’échelle laboratoire, dans des conditions environnementales simulant le futur procédé industriel, 2) une collaboration avec les partenaires industriels afin de fournir une analyse d’ingénierie préliminaire d’un procédé de fermentation des hydrolysats lignocellulosiques d’une capacité de 200 kL par cuvée. Les tests en laboratoire ont démontré une réduction appréciable des performances de fermentation de la souche recombinante étudiée, par rapport aux procédés de fermentation de 1ère génération. L’analyse de rentabilité du procédé à capacité de 200 kL montre que le procédé n’est pas rentable, affichant un rendement approximatif de -7% sur une durée de 20 ans

Alia: Antropologia di una comunità dell'entroterra siciliano

In the spring of 1995, during works for the rehabilitation of a wall that closed the grotto of the Old Cemetery in the Sicilian village of Alia, the skeletal remains of the victims of the cholera outbreak of 1837 that had been rapidly interred here were brought to light. From that moment on, the Alia project was developed without interruption, analysing the biological evolution of the local population by exploiting study methods characteristic of different anthropological disciplines, such as skeletal biology, population genetics and biodemography. The book renders account of research completed and in progress carried out by academics from the Universities of Florence, Palermo, Parma, Cagliari, Turin and Göttingen

L'Africa romana: atti dell'11. Convegno di studio

Inizia con questo volume una nuova serie degli atti dei Convegni dedicati a "L'Africa Romana", pubblicati dal Dipartimento di Storia dell'Università degli studi di Sassari: dopo i primi dieci volumi curati da Attilio Mastino, dedicati agli incontri svolti annualmente tra il 1983 ed il 1992, questo undicesimo volume stampato per iniziativa del Centro di studi interdisciplinari sulle province romane dell'Università di Sassari e dell'Institut National du Patrimoine di Tunisi contiene i testi delle relazioni e delle comunicazioni presentate a Cartagine tra il 15 ed il 18 dicembre 1994, in occasione del Convegno promosso sotto gli auspici dell' Association Internationale d'Épigraphie Grecque et Latine, dedicato al tema «La scienza e le tecniche nelle province romane del Nord Africa e nel Mediterraneo», al quale hanno partecipato oltre 200 studiosi, provenienti da 17 paesi europei ed extra-europei. Le oltre 120 comunicazioni hanno riguardato le tecniche più diverse, l'agronomia, le tecniche agricole, l'idraulica, le tecniche estrattive, l'architettura, l'urbanistica, la produzione ceramica, la pesca, la musica. Per le scienze, si segnalano numerosi studi dedicati alla geografia, alla cartografia, all'astronomia, alla medicina, alla veterinaria. Una sessione è stata riservata alle nuove scoperte epigrafiche. Come osserva Claude Lepelley nella Presentazione, questo volume segna un ulteriore allargamento geografico alle province occidentali dell'impero romano, in particolare alla Sardegna, alla Sicilia, alla Corsica, alle due Spagne, alla Lusitania. «On constate ici que les colloques de L'Africa Romana sont devenus dans nos disciplines un événement qui concerne en fait tous les spécialistes du monde romain». In occasione del Convegno di Cartagine si è proceduto alla firma di un accordo quadro tra il Rettore dell'Università di Sassari ed il Direttore dell'Institut National du Patrimoine di Tunisi per le ricerche archeologiche ed epigrafiche nel sito della colonia romana di Uchi Maius (oggi Henchir ed-Douâmis): «Ainsi, l'initiative prise en 1983 par Attilio Mastino - conclude Claude Lepelley nella Presentazione aura permis, non seulement de rythmer par de fructueuses rencontres annuelles ainsi que par de riches et punctuelles publications le travail des spécialistes, mais aussi de partir sur le terrain à la découverte de données inconnues, issues de cette terre d'Afrique qui, disait déjà Hérodote "apporte toujours quelque chose de nouveau"»

Talking Gender: La costruzione con-testuale delle Identità di Genere

The topic of the following research is focused on discursive positioning amongst social actors, whose gender falls somewhere between or outside of the sexual dualism, and contexts, characterised by a dominant heteronormative imprint. The edges of agency have been investigated, according to which a person, who passes amongst genders, claims a self representation, with regard to the peculiar symbolical and normative structure of specific contexts of interaction. In order to isolate the processes, throughout which develops a self-representation as gender, the rank of agency has been analysed, according to practices of positioning within three contexts: prison reality, workplaces and family environment. The study, therefore, aims to understand how transgender reproduce certain genderized Ideal-types, with regard to the symbolical coordinates of the context, the situativity of everyday interaction, as well as the linguistic meta-artefacts, circumscribing zones of meanings, which move in a feminine or masculine direction. The representations of self and others, within a socio-constructive perspective, are articulated along discursive productions in relation to everyday interactions and cultural and normative superstructures. Discourse, according to this approach, could be considered as a mediation artefact, which generates social meanings. The corpus of data, therefore, consists in gathering discursive material within the following contexts: - six semistructured interviews with staff members of the Sollicciano prison near Florence - five in-depth interviews with transprisoners detained in the same institute - seven in-depth interviews with transgender in private and work contexts - three diaries, written by transgender, contacted by socio-political associations in north and central Italy. These textual datas have been studied according to two methodological perspectives: Critical Analysis of the ideological matrix of discourse, with regard to the production of implicit meanings. The symbolic repertoires have been associated to conceptual macro-categories, adopting the software Transana for computer assisted discourse analysis Quali-quantitative analysis of semantic content and lexical organisation with the program for textual data analysis Alceste Results show that the constitutive elements of discursive production (lexicon, semantics, semiotics) generate narrative repertoires, with similar structure and affine representations of self and others. These units of meanings constitute the research goals of this study, focused on positioning between gender and (con)text. There emerged a sequential intersectionaliy amongst the following variables: Gender dualism ➔ Asymmetry of power ➔ Inequalities ➔ Discrimination ➔ Reified representation of gender From this process emerged different normative, structural as well as interactive practices, which, throughout universes of sense and systems of actions, socially recognised, culturally legitimised and discursively institutionalised, produce genderized Ideal-types and meanings, embedded within temporal horizons, relational sceneries and contextual limelights. With regard to prison context the edges of positioning are relegated within the institutional parameters of the penitentiary system. Language, especially, assumes a reifying function, by the moment, that semantic categories define normative links between self and context. Gender identity, actually, is circumscribed by precise discursive borders. With regard to family and workplaces, self-representation as transgender changes, according to situated symbolic coordinates. Normative superstructures influences discourse mainly on an implicit level. Agency within processes of gender identity affirmation depend from specific contexts and different modalities of positioning amongst self and other
