Dual targeting of higher-order DNA structures by azacryptands induces DNA junction-mediated DNA damage in cancer cells
2021
Abstract DNA is intrinsically dynamic and folds transiently into alternative higher-order structures such as G-quadruplexes (G4s) and three-way DNA junctions (TWJs). G4s and TWJs can be stabilised by small molecules (ligands) that have high chemotherapeutic potential, either as standalone DNA damaging agents or combined in synthetic lethality strategies. While previous approaches have claimed to use ligands that specifically target either G4s or TWJs, we report here on a new approach in which ligands targeting both TWJs and G4s in vitro demonstrate cellular effects distinct from that of G4 ligands, and attributable to TWJ targeting. The DNA binding modes of these new, dual TWJ-/G4-ligands w…

Políticas de acceso abierto a la ciencia en las universidades españolas
2013
El objetivo del artículo es analizar el estado de la cuestión de las políticas en favor del acceso abierto (OA) a la ciencia en las universidades españolas. Para ello se han establecido cinco grandes mecanismos de intervención (la creación de infraestructuras y prestación de servicios, la comunicación y difusión, la incentivación económica, la coordinación institucional así como la reglamentación u obligación) que permiten llevar a cabo políticas a favor del acceso abierto y que hemos utilizado para el análisis y la valoración de la situación. La recogida de datos se ha basado en un cuestionario enviado a los vice-rectores de investigación y se ha complementado con la consulta de directorio…
Using Crowdsourcing to Overcome Barriers to Women Entrepreneurship
2015
This chapter presents crowdsourcing as a novel way of overcoming barriers facing women entrepreneurs, offering alternatives to conventional solutions. The study analyzes three barriers to women entrepreneurship: access to financing, access to specific management knowledge, and access to information and communication technologies (ICTs). For each barrier, a different form of crowdsourcing is proposed: crowdfunding, crowd wisdom, and crowdfunded media, respectively. Using these crowdsourcing tools, women entrepreneurs can overcome major difficulties when starting businesses.
Impacto de la Sociedad del Conocimiento en la universidad y en la comunicación científica
2014
A la largo de las dos últimas décadas y como resultado de la introducción y uso intensivo de las tecnologías de la información y del conocimiento en general y de internet en particular, la universidad esta viviendo un proceso de transformación complejo que afecta a sus estructuras académicas y organizativas así como también a su concepción de metodología docente. Las TIC han evidenciado la necesidad de establecer estrategias de coherencia institucional en su uso y aplicación, así como la posibilidad de ampliar los ámbitos de acción institucional y el acceso masivo a la formación superior. Y todo ello pone de manifiesto el cambio existente de un modelo de formación basado en la transmisión d…
Power and language in a multicultural workplace
2015
Today’s work markets are increasingly shaped by the multilingual reality. The present research offers an intercultural communication perspective on language diversity and power relations at modern work environment. Study investigates how young professionals and their foreign colleagues perceive diversity affecting in their communicative behaviours in culturally heterogeneous workplace. Analysis of data from participants has been conducted through an analysis of open ended self‐report questionnaire in a multinational company where English is used daily as a corporate language. In particular, results of present study indicate that more diverse language skills are attributed to perception of p…
The self-perceived commitment and relationship maintenance behaviors among Finnish-Chinese couples in Finland : an application of the investment mode…
2015
The investment model (2003) has been widely used in romantic relationship studies but rarely in an intercultural context. This study tests the investment model by examining Finnish-Chinese couples’ self-perceptions of commitment level and relationship maintenance behaviors. A qualitative research method with deductive thematic analysis approach is applied. This study finds that Finnish-Chinese couples have relatively high level of commitment. They tend to remain in their relationships, to actively derogate alternatives, to sacrifice self-welfare for gratifying relationship well-being, to perceive their relationships as good and healthy and to choose relationship constructive responses under…
Il contratto collettivo aziendale in una prospettiva comparata. Italia, Francia, Spagna e Stati Uniti a confronto
2014
Sulla scorta del metodo comparato, la tesi analizza le recenti modifiche alla disciplina del contratto collettivo aziendale in Italia, Francia e Spagna, introdotte dalla legge e dagli accordi interconfederali; l'obiettivo è dimostrare un tendenziale avvicinamento degli stati europei analizzati al sistema nord-americano di relazioni industriali, in cui il rapporto di lavoro è regolato non tanto dalla legge o dall'accordo di categoria, ma dal contratto aziendale.Vengono inoltre analizzati i recenti accordi collettivi firmati alla Fiat ed alla Chrysler a partire dal processo di integrazione iniziato nel 2009. According to the comparative method, the thesis analyses the recent changes to the di…
Detection of an O-methyltransferase synthesising acetosyringone in methyl jasmonate-treated tobacco cell-suspensions cultures.
2013
Acetosyringone (3',5'-dimethoxy-4'-hydroxyacetophenone) is a well-known and very effective inducer of the virulence genes of Agrobacterium tumefaciens but the precise pathway of its biosynthesis in plants is still unknown. We have used two tobacco cell lines, cultured in suspension and exhibiting different patterns of accumulation of acetosyringone in their culture medium upon treatment with methyl jasmonate, to study different steps of acetosyringone biosynthesis. In the two cell lines studied, treatment with 100 mu M methyl jasmonate triggered a rapid and transient increase in acetovanillone synthase activity followed by a progressive increase in S-adenosyl-L-methionine: 5-hydroxyacetovan…
Cladosins L-O, new hybrid polyketides from the endophytic fungus Cladosporium sphaerospermum WBS017
2019
Abstract The endophytic fungus Cladosporium sphaerospermum WBS017 was obtained from healthy bulbs of Fritillaria unibracteata var. wabuensis. Fermentation of C. sphaerospermum on solid rice medium yielded three new hybrid polyketides, cladosins L−N (1–3), and a known derivative cladodionen (4). Further cultivation of this fungus on white bean medium afforded an additional new hybrid polyketide, cladosin O (5) along with three known analogues (6–8). The structures of the new compounds were elucidated using a combination of NMR and HRESIMS data. The absolute configurations of compounds 2 and 3 were determined by Mosher’s method and TDDFT-ECD calculations. All isolated compounds were evaluated…
