      Inorganic polyphosphates (polyP) are present in all living cells and several important functions have been de-scribed for them. They are involved in the response to stress conditions, such as nutrient depletion, oxidativestress ...
    • Rojas, Adriana; Sepúlveda, Hugo; Henríquez, Berta; Aguilar, Rodrigo; Opazo, Tatiana; Nardocci, Gino; Bustos, Fernando; Lian, Jane B.; Stein, Janet L.; Stein, Gary S.; van Zundert, Brigitte; van Wijnen, Andre J.; Allende Connelly, Miguel; Montecino, Martín (Wiley, 2019)
      Expression of Runx2/p57 is a hallmark of the osteoblast-lineage identity. Although several regulators that control the expression of Runx2/p57 during osteoblast-lineage commitment have been identified, the epigenetic ...
    • Ríos González, J. A.; Menéndez Proupin, Eduardo Ariel; Peña, J. L. (IOP Publishing, 2018)
      The electronic structure and thermodynamic properties of bismuth impurities in cadmium telluride (CdTe) are studied by means density functional theory calculations. The exchange and correlation are treated using the hybrid ...
    • Baeza, Marcelo; Fernández Lobato, María; Alcaíno Gorman, Jennifer; Cifuentes, Víctor (Humana Press, 2018)
      Double-stranded RNA (dsRNA) molecules are widely found in yeasts and filamentous fungi. It has been suggested that these molecules may play an important role in the evolution of eukaryote genomes and could be a valuable ...
    • Tejos, Ricardo; Osorio Navarro, Claudio; Norambuena Morales, Lorena (Humana Press, 2018)
      Chemical compounds are useful to perturb biological functions in the same way as classical genetic approaches take advantage of mutations at the DNA level to perturb gene function. The use of bioactive chemicals currently ...
    • Vargas Milne, Alexander; Ruiz Flores, Macarena; Soto Acuña, Sergio; Haidr, Nadia; Acosta Hospitaleche, Carolina; Ossa Fuentes, Luis; Muñoz Walther, Vicente (Oxford, 2017)
      Embryonic muscular activity (EMA) is involved in the development of several distinctive traits of birds.Modern avian diversity and the fossil record of the dinosaur-bird transition allow special insight into their ...
    • Flores, Mauricio A.; Orellana, Walter; Menéndez Proupin, Eduardo (American Physical Society, 2017)
      We investigate the self-compensation mechanism in phosphorus-doped CdTe. The formation energies, charge transition levels, and defect states of several P-related point defects susceptible to cause self-compensation are ...
    • Aliaga, Juan Antonio; Zepeda, Trino; Araya, Juan Francisco; Paraguay Delgado, Francisco; Benavente, Eglantina; Alonso Núñez, Gabriel; Fuentes, Sergio; González Moraga, Guillermo (MDPI AG, 2017)
      Single-layer, ultrasmall ReS2 nanoplates embedded in amorphous carbon were synthesized from a hydrothermal treatment involving ammonium perrhenate, thiourea, tetraoctylammonium bromide, and further annealing. The rhenium ...
    • Aliaga, J. A.; Zepeda, T. N.; Pawelec, B. N.; Araya, J. F.; Antúnez García, J.; Farías, M. H.; Fuentes, S.; Galván, D.; Alonso Núñez, G.; González, G. (Springer, 2017)
      An unsupported microspherical ReS2 catalyst, consisting in self-assembled nano-layers, was evaluated in the hydrodesulfurization (HDS) of 3-methylthiophene showing an excellent catalytic activity. The samples were ...
    • Carrasco, Mario; Alcaíno Gorman, Jennifer; Cifuentes Guzmán, Víctor; Baeza Cancino, Marcelo (BioMed Central, 2017)
      Background: Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most ...
    • González Henríquez, Carmen M.; Terraza, Claudio; Sarabia, Mauricio; Vera, Alejandra; Aliaga Cerón, Álvaro (Taylor and Francis, 2017)
      Correlation between theoretical and experimental (infrared and Raman spectroscopies) vibrational spectra of two compounds, both with a silyl group present in their main chain and with an optically active structure (L-valine) ...
    • Cantillano, Camilo; Morales Inostroza, Luis; Real, Bastián; Rojas Rojas, Santiago; Delgado, Aldo; Szameit, Alexander; Vicencio, Rodrigo A. (Elsevier, 2017)
      We experimentally study the transport properties of dipolar and fundamental modes on one dimensional (1D) coupled waveguide arrays. By carefully modulating a wide optical beam, we are able to effectively excite dipolar or ...
    • Coronel, Aníbal; Maulén, Christopher; Pinto Jiménez, Manuel; Sepúlveda, Daniel (Academic Press, 2017)
      In this paper, ordinary and exponential dichotomies are defined in differential equations with equations with piecewise constant argument of general type. We prove the asymptotic equivalence between the bounded solutions ...
    • Ramírez Collio, Karla; Vergara, Pablo M.; Simonetti Zambelli, Javier Andrés (Elsevier, 2017)
