Plants are sessile organisms that throughout evolution have developed complex mechanisms to survive adverse environmental conditions, such as extreme temperatures and pathogens attack. Plants exposed to low temperatures are able to activate different adap


Utilizando el principio de la enantioselectividad de las enzimas, se utilizó una enzima comercial (NOVOZYM 435) para producir un precursor farmacéutico quiral (R-Monometil fenil glutárico) con la mayor pureza enantiomérica posible. Se utilizó como sustrato de la reacción Dimetil fenil glutárico, ...


In Chile, Capsicum annuum L. cv. "Cacho de Cabra” berry fruits are used for the manufacture of a traditional chilli powder known as Merkén. The agricultural practices used by Merkén local producers are empirical and do not consider the prevention of mycotoxigenic fungi and, in the last years, myc...

No Chile, o fruto da planta Capsicum annuum L. cv. "Cacho de Cabra” é usado para a produção dum piri-piri em pó chamado Merkén. As práticas usadas pelos produtores locais de Merkén são altamente empíricas e não consideram a prevenção contra fungos micotoxigénicos pelo que, nos últimos anos, conta...


Consolidated memories can return to a labile state if they are reactivated by unpredictable reminders. To persist, active memories must be re-stabilized through a process known as reconsolidation. Although there is consistent behavioral evidence about this process in humans, the retrieval proc...


El uso de compuestos antibacterianos naturales en productos farmacéuticos es comúnmente limitado debido a que no son lo suficientemente potentes. En consecuencia, el objetivo de este trabajo fue desarrollar micropartículas poliméricas biodegradables (utilizando quitosano (CH) como material de mat...


The high conductance, calcium-activated potassium (MaxiK) channel is widely expressed among mammalian tissues. The activity of the channel is increased by membrane depolarization and by increases in intracellular calcium concentration. The channel is assembled in the membrane as a homotetramer of...

El canal de potasio activado por calcio de alta conductancia MaxiK está presente en casi todos los tejidos de mamíferos. La actividad del canal aumenta con incrementos del calcio intracelular y la despolarización de la membrana celular. El canal se forma como un homotetrámero de su subunidad α –u...


In this work we show how could have been formed intermediate mass black holes in the early Universe through stellar collisions between the first stars of the Universe that formed part of dense stellar clusters. Our work focuses on studying the first star clusters, formed by population III stars w...
