(Elsevier, 2018)Selenospinels, CuCr2-xMxSe4 (M = Zr and Sn), were synthesized via conventional solid-state reactions. The crystal structure of CuCr1.5Sn0.5Se4, CuCr1.7Sn0.3Se4, CuCr1.5Zr0.5Se4, and CuCr1.8Zr0.2Se4 were determined using ...
-
(2013-06)ADP-dependent glucokinases represent a unique family of kinases that belong to the ribokinase superfamily, being present mainly in hyperthermophilic archaea. For these enzymes there is no agreement about the magnitude of ...
-
(Sociedad Chilena de Quimica, 1999)The crystal and molecular structures of (E)-1-(3,4,5-trimethoxyphenyl)-2-nitroethene (1), C11H13NO5, Mr = 239.2, and (E)-1-(3,4,5-trimethoxyphenyl)-2-nitropropene (2), C12H15NO5, Mr = 253.3, were determined by X-ray ...
-
(BLACKWELL, 2006-09)Escherichia coli contains two phosphofructokinases, Pfk-1 and Pfk-2, which belong to unrelated protein families. In addition to catalytic function, the enzymes have converged in showing substrate inhibition by the nucleotide ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008-08-22)Phosphofructokinase-1 and -2 (Pfk-1 and Pfk-2, respectively) from Escherichia coli belong to different homologous superfamilies. However, in spite of the lack of a common ancestor, they share the ability to catalyze ...
-
(2013)The CSRNP (cystein-serine-rich nuclear protein) transcription factors are conserved from Drosophila to human. Functional studies in mice, through knockout for each of their paralogs, have resulted insufficient to elucidate ...
-
(ACADEMIC PRESS INC., 2013-02)A new family of Cu2Mn1-xCoxSnS4 chalcogenides has been synthesized by conventional solid-state reactions at 850 degrees C. The reactions products were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray ...
-
(Universidad de Chile, 2017)En esta investigación se estudio la estructura genético-poblacional de P. flavescens mediante marcadores mitocondriales y nucleares en localidades continentales e insulares, con el objetivo de evaluar si existe un patrón ...
-
(Universidad de Chile, 2022)Conocer acerca de los niveles de endemismo en determinadas zonas resulta ser fundamental en la implementación de planes de conservación, en especial en áreas remotas y de pequeño tamaño. Rapa Nui corresponde a una de ...

(2002)Cucurbitacin F and the cyanogenetic compounds prunasin were isolated and identified from the seeds of Kageneckia angustifolia.
-
(Springer, 2013)Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples ...
-
(University of Prince Edward Island, 2020)Sea turtles are deeply rooted in Pacific cultures. Rapa Nui (Easter Island, Chile) has a complex societal and ecological history and marine resources have always been exploited; nevertheless, little is known about relationships ...
-
(ASOCIACION QUIMICA ARGENTINA, 1975)Fagara mayu leaves yield four furanocoumarins, identified as psoralen (1), bergapten (11), xanthotoxin (111), and isopimpinellin (IV). The occurrence of these compounds together with furanoquinolines and canthinone, and ...
-
(MDPI, 2021)Following an injury, axons of both the central nervous system (CNS) and peripheral nervous system (PNS) degenerate through a coordinated and genetically conserved mechanism known as Wallerian degeneration (WD). Unlike ...
-
(Wiley, 2022)Habitat loss and shifts associated with climate change threaten global biodiversity, with impacts likely to be most pronounced at high latitudes. With the disappearance of the tundra breeding habitats, migratory shorebirds ...
-
(2012)We study particle current in a recently proposed model for coherent quantum transport. In this model, a system connected to mesoscopic Fermi reservoirs (meso-reservoir) is driven out of equilibrium by the action of ...
-
(Humana Press, 1997)Investigation of phototransduction in invertebrate photoreceptors has revealed many physiological and biochemical features of fundamental biological importance. Nonetheless, no complete picture of phototransduction has yet ...
