Z(d) group shifts and Bernoulli factors

Boyle, Mike;Schraudner, Michael (2008-04)

In this paper, a group shift is an expansive action of Z(d) on a compact metrizable zero-dimensional group by continuous automorphisms. All group shifts factor topologically onto equal-entropy Bernoulli shifts;....

Zebrafish BarH-like genes define discrete neural domains in the early embryo

Colombo, Alicia;Reig, Germán;Mione, Marina;Concha, Miguel L. (2006-04)

BarH (Barhl) genes encode for highly conserved homeodomain-containing transcription factors involved in critical functions during development, including cell fate specification, migration and survival. Here, we....

Zebrafish cellular nucleic acid-binding protein: gene structure and developmental behaviour

Armas, Pablo;Cachero, Sebastián;Lombardo, Verónica A.;Weiner, Andrea;Allende, Miguel L.;Calcaterra, Nora B. (2004-08-04)

Here we analyse the structural organisation and expression of the zebrafish cellular nucleic acid-binding protein (zCNBP) gene and protein. The gene is organised in five exons and four introns. A noteworthy fea....

Zebrafish cnbp Intron1 Plays a Fundamental Role in Controlling Spatiotemporal Gene Expression During Embryonic Development

Weiner, Andrea;Allende, Miguel L.;Calcaterra, Nora B. (2009-09-02)

Cellular nucleic acid binding protein (CNBP) is a strikingly conserved zinc-finger nucleic acid chaperone required for forebrain development. Its depletion causes forebrain truncation mainly as a consequence o....

Zebrafish (Danio rerio) as a model for studying the genetic basis of copper toxicity, deficiency, and metabolism

Hernández, Pedro;Allende, Miguel L. (2008-09-01)

Unicellular eukaryotes and cultured cells from several animal species were invaluable in discovering the mechanisms that govern incorporation, handling, and excretion of copper at the cellular level. However, u....

ZERO-ORDER AND 1ST-DERIVATIVE SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF RUTHENIUM AFTER EXTRACTION OF ITS ION ASSOCIATION COMPLEX WITH 2,4,6-TRIS(2'-PYRIDYL)-1,3,5-TRIAZINE AND PICRATE

Morales, A.;Toral Ponce, María;Richter D., Pablo;Silva, M. (1992)

A solvent extraction-spectrophotometric determination of trace amounts of ruthenium has been developed, based on the formation of an ion association complex of ruthenium (III) with 2,4,6-tris(2'-pyridyl)-1,3,5-....

Zig-Zag : un gigante de papel. Llegado gráfico de las revistas de la época

Zinc absorption from a micronutrient-fortified dried cow's milk used in the Chilean National Complementary Food Program

Ruz, Manuel;Codoceo, Juana;Inostroza, Jorge;Rebolledo, Annabella;Krebs, Nancy F.;Westcott, Jamie E.;Sian, Laei;Hambidge, K. Michael (2005-12)

The objective was to compare the absorption of zinc from a micronutrient-fortified dried cow's milk, which is part of the Chilean National Complementary Food Program, with that from a standard nonfortified milk....

Zinc inhibits nonheme iron bioavailability in humans

Olivares, Manuel;Pizarro, Fernando;Ruz, Manuel (2007)

There is increasing concern about potential negative interactions in combined iron and zinc supplementation. The aim of the present study was to determine the dose-response effect of zinc, given as a solution, ....

Zinc Oxide Nanostructures by Solvothermal Synthesis

Segovia, M.;Sotomayor, C.;González, G.;Benavente, E. (2012)

The synthesis, characterization, and properties of three types of one-dimensional zinc oxide nanostructures are described. They were obtained by solvothermal treatment of nanometric zinc oxide as zinc ion sou....
