Degradation of aromatic compounds through the β-ketoadipate pathway is required for pathogenicity of the tomato wilt pathogenFusarium oxysporumf. sp.…
2012
Plant roots react to pathogen attack by the activation of general and systemic resistance, including the lignification of cell walls and increased release of phenolic compounds in root exudate. Some fungi have the capacity to degrade lignin using ligninolytic extracellular peroxidases and laccases. Aromatic lignin breakdown products are further catabolized via the β-ketoadipate pathway. In this study, we investigated the role of 3-carboxy-cis,cis-muconate lactonizing enzyme (CMLE), an enzyme of the β-ketoadipate pathway, in the pathogenicity of Fusarium oxysporum f. sp. lycopersici towards its host, tomato. As expected, the cmle deletion mutant cannot catabolize phenolic compounds known to …
Ecological fitness of the biocontrol agent Fusarium oxysporum Fo47 in soil and its impact on the soil microbial communities
2009
Some nonpathogenic strains of Fusarium oxysporum can control Fusarium diseases responsible for severe damages in many crops. Success of biological control provided by protective strains requires their establishment in the soil. The strain Fo47 has proved its efficacy under experimental conditions, but its ecological fitness has not been carefully studied. In a series of microcosm studies, the ability of a benomyl-resistant mutant Fo47b10 to establish in two different soils was demonstrated. One year after its introduction at two concentrations in the disinfected soils, the biocontrol agent (BCA) established at similar high population densities, whereas in the nondisinfected soils it survive…
Genetic and Epigenetic Factors of Takotsubo Syndrome: A Systematic Review
2021
Takotsubo syndrome (TTS), recognized as stress’s cardiomyopathy, or as left ventricular apical balloon syndrome in recent years, is a rare pathology, described for the first time by Japanese researchers in 1990. TTS is characterized by an interindividual heterogeneity in onset and progression, and by strong predominance in postmenopausal women. The clear causes of these TTS features are uncertain, given the limited understanding of this intriguing syndrome until now. However, the increasing frequency of TTS cases in recent years, and particularly correlated to the SARS-CoV-2 pandemic, leads us to the imperative necessity both of a complete knowledge of TTS pathophysiology for identifying bi…
P463 COVID-19 vaccination willingness and hesitancy in patients with Inflammatory Bowel Diseases (IBD): analysis of determinants in a national survey…
2021
Abstract Background Vaccine hesitancy, the delay in acceptance or refusal of vaccination despite its availability, represents a threat to the diffusion and lethality of infectious diseases. COVID-19 vaccination has been recommended by national and international organizations in patients with Inflammatory Bowel Diseases (IBD). The aim of the study was to evaluate COVID-19 vaccine willingness and hesitancy in a population of Italian patients with IBD, and their determinants. Methods In February 2021 an online questionnaire focused on COVID-19 vaccine was proposed to a representative sample of Italian IBD patients. Socio-demographic characteristics, IBD features, lifestyle, perception of COVID…

3D models of humanoid soccer robot in USAR sim and robotics studio simulators
2008
This paper describes our experience in the simulation of humanoid soccer robots using two general purposes 3D simulators, namely USARSim and Microsoft Robotics Studio. We address the problem of the simulation of a soccer match among two teams of small humanoid robots in the RoboCup Soccer Kid-Size Humanoid competitions. The paper reports the implementation of the virtual models of the Robovie-M humanoid robot platform in the two simulators. Robovie-M was the robot used by our team "Artisti" in the RoboCup 2006 competitions. This paper focuses on the procedures needed to implement the virtual models of the robot and in the details of the models. We describe experiments assessing the feasibi…
Orlando Furioso dalla specola del costrutto causativo
2017
Analisi e riflessioni sulle ricorrenze del costrutto causativo nell'Orlando Furioso che si rivela tratto saliente della lingua e dell'espressione dell'opera. Il poema di Ariosto pullula naturalmente di attori che, osservati dalla specola del costrutto causativo, si qualificano appunto come né sovrumani né subumani. Attori siffatti ne sono i protagonisti. Le loro vicissitudini costituiscono il tema dell’opera e ne sostanziano la trama. Che il costrutto causativo sia tanto frequente nel Furioso non è dunque un accidente e il dato è a questo punto comprensibile, perché integrato in un sistema. Il costrutto causativo è nel cuore del processo narrativo, ne è un motore.
