Y chromosome diversity in Aztlan descendants and its implications for the history of central Mexico (Cell Press, 2021)Native Mexican populations are crucial for understanding the genetic ancestry of Aztec descendants and coexisting ethnolinguistic groups in the Valley of Mexico and elucidating the population dynamics of the prehistoric ...

(American Chemical Society, 2002-11)A new norditerpenoid, yaretol (1), was isolated from the whole plant of Azorella madreporica. The structure of 1 was established by one- and two-dimensional NMR techniques and confirmed by X-ray diffraction analysis.

Zebrafish and medaka : model organisms for a comparative developmental approach of brain asymmetry (Universidad de Chile, 2009)
-
(FRONTIERS MEDIA, 2016)Angiogenesis is the process through which new blood vessels are formed from preexisting ones and plays a critical role in several conditions including embryonic development, tissue repair and disease. Moreover, enhanced ...
-
(ELSEVIER, 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 feature of the ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 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 of a reduction ...
-
(2002)By using retroviral insertional mutagenesis in zebrafish, we have identified a recessive lethal mutation in the not really started (nrs) gene. The nrs mutation disrupts a gene located in linkage group 3 that is highly ...
-
(Karger, 2015)Zebrin II (ZII) is a glycolytic enzyme expressed in cerebellar Purkinje cells. In both mammals and birds, ZII is expressed heterogeneously, such that there are sagittal stripes of Purkinje cells with a high ZII expression ...
-
(2011)Hybrid organic-inorganic semiconductor nanocomposites of layered zinc oxide/carboxylic acids were fabricated. Products are pure phases with structures constituted by double-layer sheets of the inorganic component sandwiched ...
-
(Nature, 2021)In this contribution, we explore the potential of atomic layer deposition (ALD) techniques for developing new semiconductor metal oxide composites. Specifically, we investigate the functionalization of multi-wall trititanate ...
-
(Universidad de Chile, 1985)El objetivo de esta tesis fue evaluar los efectos de la presencia de manchones de arbustos en el matorral de la distribución de microclimas y explorar el posible efecto biológico de la zonación microclimatica, especialmente ...
-
(GEOLOGICAL SOC AMER, 2011-05)Terrestrial records from 41 to 52 degrees S across the Southern Hemisphere reveal nearly synchronous multimillennial trends in moisture derived from the Southern Westerly Winds (SWW) since 14 ka, pointing to a marked zonal ...

(1998)1. Ten racemic β-alkoxy-β-phenylethylamines were found to elicit concentration dependent contraction of the isolated rat thoracic aorta with apparent pot values in the 4.56-6.76 range. With one exception, which produces ...
-
(2010)β-Adrenergic receptor stimulation can significantly facilitate synaptic potentiation in the hippocampus and enhance memory processes, but its effect on neocortical plastic mechanisms is less conclusive. In the present study ...
-
(MDPI, 2021)Drugs are widely used as therapeutic agents; however, they may present some limitations. To overcome some of the therapeutic disadvantages of drugs, the use of beta-cyclodextrin-based nanosponges (beta CDNS) constitutes a ...
-
(Wiley Blackwell, 2016)Currently, odorant-binding proteins (OBPs) are considered the first filter for olfactory information for insects and constitute an interesting target for pest control. Thus, an OBP (HeleOBP) from the scarab beetle Hylamorpha ...
