Naphthalenone polyketides produced by Neofusicoccum parvum, a fungus associated with grapevine Botryosphaeria dieback
2016
A strain of Neofusicoccum parvum isolated from declining vines was pathogenic to grapevine cultivar Inzolia in Sicily. This strain produced some metabolites in liquid medium. Crude extract, through a bio-guided purification process, yielded four naphthalenone polyketides. They were identified by comparison with spectroscopic data and optical proprieties reported in literature as: (3S, 4S)-7-ethyl-3,4,8-trihydroxy-6-methoxy-3,4-dihydro-1-(2H)-naphthalenone, (3S*, 4S*)-3,4-dihydro-3,4,8-trihydroxy-7-(1-hydroxyethyl)-6-methoxy-1-(2H)-naphthalenone, (4S)-3,4-dihydro-4,8-dihydroxy-1-(2H)-naphthalenone, named botryosphaerones D and A, isosclerone, respectively, and (3S*,4S*)-3,4,5-trihydroxy-1-…
Stato sanitario e micorrizazione in specie arboree forestali: casi studio in Italia
2016
La sanità delle piante è notoriamente correlata a elevati livelli di micorrizazione, soprattutto in ospiti strettamente dipendenti dalla simbiosi. Eventuali fattori di stress, abiotici o biotici, agenti di deperimento alterano il bilancio fotosintetico e influenzano, spesso negativamente, l’associazione mutualistica, aggravando così lo stato di sofferenza delle piante. Relativamente alle piante forestali, diversi studi hanno confermato l’intima interazione tra stato sanitario e micorrizazione. In questa nota si riportano i risultati di nostre indagini, condotte in due Regioni ecologicamente molto diverse, Lazio e Sicilia, rilevando lo stato micorrizico di piante di Fagus sp., Pinus sp. e Qu…
Course and Predictors of Pain and Physical Functioning in Patients with Hip Osteoarthritis: Systematic Review and Meta-Analysis
2016
Objective: To systematically summarize the literature on: (i) the course of pain and physical functioning; and (ii) predictors of deterioration of pain and physical functioning in patients with osteoarthritis of the hip. Methods: A literature search was conducted in PubMed, CINAHL, Embase, PsychINFO and SPORTDiscus up to July 2015. Meta-analyses and qualitative data syntheses were performed. Results: Eleven of the 15 included studies were of high quality. With regard to the course of pain and physical functioning, high heterogeneity was found across studies (I2 >71%) and within study populations (reflected by large standard deviations of change scores). Therefore, the course of pain and phy…
Le "vrai portrait" du Grand Comte Roger. De Florence à la Sicile: aux origines d'une équivoque
2006
Partendo da due dipinti pressoché identici del XVII secolo conservati a Patti (ME) e Troina (EN), che raffigurano il ritratto ideale del Gran Conte Ruggero Hauteville, protagonista della liberazione della Sicilia dal dominio islamico, se ne è riconosciuto il modello in un dipinto di Cristofano Allori firmato e datato 1590, oggi agli Uffizi ma proveniente dalla Badia Fiorentina, avente per soggetto il Marchese Ugo di Toscana. Il saggio propone inoltre di riferire le opere siciliane al medesimo pittore e alla comune committenza del vescovo Vincenzo Napoli (+1648). Starting from two almost identical paintings from the 17th century preserved in Patti (ME) and Troina (EN), which depict the ideal…
Technical English for agriculture
2021
As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…
Propuesta de monitorización integral de la calidad ambiental del interior de la Iglesia de los Santos Juanes de Valencia
2020
Para la correcta conservación de los bienes de interés cultural (BIC), debe existir una óptima calidad ambiental interior. La monitorización de esta calidad ambiental, tradicionalmente, incluye el estudio de la humedad y la temperatura de los espacios interiores ya que es bien conocido que sus valores elevados y fluctuaciones rápidas pueden alterar los materiales constitutivos de las obras de arte. Sin embargo, hay muchos otros parámetros que se deben estudiar para tener una visión completa de los riesgos potenciales relacionados con ambientes patrimoniales. En este trabajo, planteamos la importancia de una monitorización integral sistemática de la calidad ambiental de un bien patrimonial q…
Perception of pathogenic or beneficial bacteria and their evasion of host immunity: pattern recognition receptors in the frontline
2015
International audience; Plants are continuously monitoring the presence of microorganisms to establish an adapted response. Plants commonly use pattern recognition receptors (PRRs) to perceive microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) which are microorganism molecular signatures. Located at the plant plasma membrane, the PRRs are generally receptor-like kinases (RLKs) or receptor-like proteins (RLPs). MAMP detection will lead to the establishment of a plant defense program called MAMP-triggered immunity (MTI). In this review, we overview the RLKs and RLPs that assure early recognition and control of pathogenic or beneficial bacteria. We also highlight the crucial func…
Active lighting applied to three-dimensional reconstruction of specular metallic surfaces by polarization imaging
2006
International audience; In the field of industrial vision, the three-dimensional inspection of highly reflective metallic objects is still a delicate task. We deal with a new automated three-dimensional inspection system based on polarization analysis. We first present an extension of the shape-from-polarization method for dielectric surfaces to metallic surfaces. Then, we describe what we believe to be a new way of solving the ambiguity concerning the normal orientation with an active lighting system. Finally, applications to shape-defect detection are discussed, and the efficiency of the system to discriminate defects on specular metallic objects made by stamping and polishing is presente…
L'invention de la Valeur Universelle Exceptionnelle de l'Unesco
2015
De la Valeur Universelle Exceptionnelle de 1972, en passant par la Convention pour la reconnaissance de l'immatérialité de 2003, le patrimoine mondial de l'UNESCO, à l'importante plasticité conceptuelle, ne cesse d'évoluer. Cet ouvrage invite au débat sur l'évolution du patrimoine mondial, à travers trois axes : diachronique, interactionniste et communicationnel, mais aussi politique et prospectif.
Struttura galleggiante ad elevata stabilità (Floating structure with high stability)
2015
DESCRIZIONE GENERALE La struttura galleggiante innovativa è composta da diversi elementi modulari collegati fra loro. La composizione modulare della struttura consente di conferirle la lunghezza dettata dalle particolari esigenze da soddisfare. Tipiche applicazioni della struttura galleggiate innovativa sono i pontili, le passerelle pedonali o ciclabili su specchi d'acqua, e in generale le opere finalizzate a consentire lo spostamento di persone, merci e/o veicoli fra punti di uno specchio d'acqua (marino o lacustre) utilizzando strutture galleggianti. Ogni modulo, lungo 10-15 m, è tenuto a galla dalla spinta di Archimede sulle sue parti immerse (le carene), spinta che nella struttura innov…
