      We kinetically studied the reaction between endogenous thiols such as -c-glutamylcysteine (c-Glu-Cys), cysteine (Cys), glutathione (GSH), homocysteine (Hcy), cysteinylglycine (Cys-Gly), and dihydrolipoic acid (DHLA)- ...

      Aim In deserts, past climate change (and particularly past rainfall variability) plays a large role in explaining current plant species distributions. We ask which species were most and which were least affected by changes ...
    • Flores, Oriana; Alcaíno Gorman, Jennifer; Fernández Lobato, María; Cifuentes Guzmán, Víctor; Baeza Cancino, Marcelo (Springer, 2015)
      Two dsRNAs of estimated lengths of 5 (L1) and 3.7 (L2) kpb are commonly found in strains of the basidiomycetous yeast Xanthophyllomyces dendrorhous, and the presence of virus-like particles (VLPs) have been described in ...
    • Aliaga, Juan Antonio; Araya, Juan Francisco; Lozano, Harold; Benavente Espinosa, Eglantina; Alonso Núñez, Gabriel; González Moraga, Guillermo (Elsevier, 2015)
      Dense microspheres consisting of poorly crystalline ReS2 embedded in carbon were synthesized with a high yield via a facile one-pot solvothermal route, by reacting dirhenium decacarbonyl, elemental sulfur and an aromatic ...
    • Huete Pérez, Jorge A.; Álvarez, Pedro J. J.; Schnoor, Jerald L.; Rittmann, Bruce E.; Clayton, Anthony; Acosta, María L.; Bicudo, Carlos E. M.; Arroyo, Mary T.

      Seeking economic growth and job creation to tackle the nation's extreme poverty, the Nicaraguan government awarded a concession to build an interoceanic canal and associated projects to a recently formed Hong Kong based ...
    • Quiroga Roger, Diego; Babul Cattán, Jorge; Guixé Leguía, Victoria Cristina (Springer, 2015)
      Human ribokinase (RK) is a member of the ribokinase family, and is the first enzyme responsible for D-ribose metabolism, since D-ribose must first be converted into D-ribose-5-phosphate to be further metabolized and ...
    • Gallo, N.; Molina Gálvez, Mario (IOP Publisihing, 2015)
      We examine bulk and surface bound states in the continuum (BIC), that is, square-integrable, localized modes embedded in the linear spectral band of a discrete lattice including interactions to first and second nearest ...
    • Moreira Ramos, Sandra; Rojas, Diego; Montes, Matías; Urbina, Fabiola; Miralles, Vicente; Maldonado, Edio (Wiley-Blackwell, 2015)
      In Schizosaccharomycespombe, ribosomal protein gene (RPG) promoters contain a TATA analogue element called the HomolD box. The HomolD-binding protein Rrn7 forms a complex with the RNA polymeraseII machinery. Despite the ...
    • Bellenberg, Soren; Díaz Beneventi, Mauricio; Noel, Nanni; Sand, Wolfgang; Poetsch, Ansgar; Dominique Guiliani, Nicolás; Vera, Mario (Elsevier, 2014)
      Bioleaching of metal sulfides is an interfacial process where biofilm formation is considered to be important in the initial steps of this process. Among the factors regulating biofilm formation, molecular cell-to-cell ...
    • Hayward, Jeremy; Horton, Thomas; Pauchard, Aníbal; Núñez, Martín (Ecological Soc Amer, 2015)
      Like all obligately ectomycorrhizal plants, pines require ectomycorrhizal fungal symbionts to complete their life cycle. Pines introduced into regions far from their native range are typically incompatible with local ...
    • Bultinck, Patrick; Jayatilaka, Dylan; Cárdenas, Carlos (Elsevier, 2015)
      We examine the dependence of atomic properties derived from the Quantum Theory of Atoms in Molecules and the Hirshfeld-I method on the existence of (quasi-)degenerate states. As atomic charges are mostly used to quickly ...
    • Charrier, Andrés; Correa, Claudio; Castro, Camila; Méndez, Marco (Magnolia Press, 2015)
      Based on morphological and molecular evidence (mitochondrial and nuclear sequences) we describe a new species of spiny-chest frog, Alsodes cantillanensis, from central Chile (around 34 degrees S). The type locality, Quebrada ...
    • Moreno Moncada, Patricio; Alloway, B.; Villarosa, G.; Outes, V.; Henríquez, W.; Pol-Holz, R. de; Pearce, N. (Geological Soc Amer, 2015)
      Volcan Chaitan (southern Chile, similar to 43 degrees S) initiated an historically unprecedented eruption in A.D. 2008, surprising the local inhabitants, Chilean and Argentine authorities, and the geologic community. ...
    • Haro, Daniela; Aguayo Lobo, Anelio; Blank, Olivia; Cifuentes, Constanza; Dougnac, Catherine; Arredondo, Cristóbal; Pardo, Catalina; Cáceres Sáez, Iris (Univ Valparaíso, 2015)
      We report the mass stranding of 46 false killer whales in the Strait of Magellan in February 2013. We present observation-based information about body size, sex, dental formula and necropsies. Sexual dimorphism in body ...
    • Araya, Juan Francisco; Araya, Marta Esther (Museum für Naturkunde, 2015)
