Estas actuán como simbiontes nucleares e inducen en las células portadoras divisiones nucleares que sirven para autoperpetuarse en los nuevos núcleos (formas reproductivas). Algunos streptococcus son capaces de salir de als células e infectar nuevos núcleos (formas infectivas). Ambos mecanismos, junto con la liberación de metabolitos, originan una rápida progresión tumoral que explica el crecicimento y diseminación de las células cancerosas. La destrucción espontánea o inducida de las células tumorales sirve de liberación y diseminación, siendo un factor agravante para el organismo. Estos hallazgos abren nuevas perspectivas patogénicas, diagnósticas y terapeúticas en esta severa y a menudo mortal enfermedad.

B-Corporations – an emergent phenomenon in Latin America since 2012 - have an annual turnover of less than 2 million dollars and employ fewer than 10 employees on average. There are 369 Certified B-Companies nowadays. Among Certified B-Corps, 85% of these companies' employ between 0 and 49 workers. One great challenge that must be addressed in the next few years is the employability of young people aged between 15 and 24 years old in Latin America. Although there have been several initiatives to face this issue, the outcomes have not proved to be enough so far both in terms of employment rates and job opportunities. By the same token, women –regardless of age groups- have also shown lower employability rates as well as fewer job opportunities as compared to men. The aim of this research is to answer the following two questions regarding B-Corps in Argentina, Chile and Uruguay: Could certified or prospective B-Corps generate jobs for young people aged between 15 and 24 years old neither working nor studying ("ni ni")? Could these companies generate jobs for women? This study seeks to shed some light on the issue of whether B-Corps are a genuine means of employability for these...

¡Aprende a tejer prendas de moda! Todas las prendas que tejes llevan algo muy especial, aunque solo sea el recuerdo del momento en que las tejimos, algo que las hace diferentes. Regalar una prenda tejida por uno mismo es regalar no solo la prenda en sí, pero también un pedacito de nosotros, de nuestro tiempo e ilusión. Tejer es relajante, baja el ritmo de los latidos del corazón, nos ayuda a evadirnos de los problemas del día a día, nos hace conservar y entrenar la memoria, nos vuelve más inteligentes..., los beneficios son innumerables. Cuando tejer llevaba años relacionándose al pasado, a las abuelitas y a la naftalina, llegaron WE ARE KNITTERS, que decidieron quitar todo esos prejuicios y hacer que tejer no sea cosa del pasado, sino todo lo contrario. Cuando la tradición de tejer se estaba perdiendo, Pepita y Alberto decidieron renovar la imagen y la experiencia de tejer algo con tus propias manos, implantando en España la imparable corriente de nuevos tejedores que se originó en Nueva York.
