(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 ...
-
(Elsevier, 2018)The inhibition of electrons-holes recombination and enhancement of visible light photocatalytic activitywere accomplished by the synthesized TiO2/CS nanocomposites system. In this present work, the differentweight ratio ...
-
(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 ...
-
(Elsevier, 2012)Crystallization of sodium perrhenate (NaReO4) from aqueous solution was studied by means of laboratory scale experiments at 298 K. NaReO4 has a very high solubility in aqueous solution (>1130 g/L at 298 K) so crystallization ...
-
(Hindawi Publishing Corporation, 2015)A systematic study of the synthesis of V2O5 nanostructured materials using macromolecular PS-co-4-PVP center dot(VCl3)(y) and chitosan center dot(VCl3)(y) complexes is presented. It is demonstrated that various coordination ...

(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 ...
-
(Nature, 2020)The processes and ranges of intensive variables that control magma transport and dyke propagation through the crust are poorly understood. Here we show that textural and compositional data of olivine crystals (Mg/Fe, Ni ...

(Elsevier, 2017)The integration between solar energy and seawater desalination is an interesting option in northern Chile due to a high solar potential in the Atacama Desert, where most of the mining operations are located. This industry ...
-
(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 ...
-
(2013)Objectives: We aimed to explore physiological responses to the six-minute walk test (6MWT) and assess computed tomographic (CT) features of the lungs and thigh muscle in order to determine contributors to dyspnea intensity ...
-
(Universidad de Chile, 2010)A lo largo de los años he visto como los jóvenes abandonan la ciudad en busca de mejores oportunidades, y la ciudad desesperanzada lucha por emerger frente a una situación de adversidad frente al progreso. Ante esto surge ...
-
(2009)To study the variability at the myotonic dystrophy protein kinase (DMPK) gene in a Chilean sample of healthy people. DM1 is an autosomal dominant disorder caused by an expansion of a (CTG) repeat at the 3′-UTR of the gene ...
-
(2003-08)We present the second gravitationally lensed quasar discovered during the course of a Hubble Space Telescope Space Telescope Imaging Spectrograph snapshot survey for small-separation gravitational lenses. CTQ 327 is a ...
-
(1999-10)We report the discovery and ground-based observations of the new gravitational lens CTQ 414. The source quasar lies at a redshift of z\1.29 with a B magnitude of 17.6. Ground-based optical imaging reveals two point sources ...
-
(2000-03)We report the discovery of the new double quasar CTQ 839. This B\18.3, radio-quiet quasar pair is separated by 2A.1 in BRI and H Ðlters, with magnitude di erences of *mB\2.5, *mR\*mI\1.9, and *mH\2.3. Spectral observations ...
