Ramírez-Ramírez JZ, Vargas R, Garza J, Gázquez JL.
PMID: 20666541
J Phys Chem A. 2010 Aug 05;114(30):7945-51. doi: 10.1021/jp100309c.

In the chemistry of metallic complexes, two important concepts have been used to rationalize the recognition and selectivity of a host by a guest: preorganization and complementarity. Both of these concepts stem from geometrical features. Less explored in the...

Multisegmented Nanowires: a Step towards the Control of the Domain Wall Configuration.

Scientific reports

Berganza E, Jaafar M, Bran C, Fernández-Roldán JA, Chubykalo-Fesenko O, Vázquez M, Asenjo A.
PMID: 28912534
Sci Rep. 2017 Sep 14;7(1):11576. doi: 10.1038/s41598-017-11902-w.

Cylindrical nanowires synthesized by controlled electrodeposition constitute excellent strategic candidates to engineer magnetic domain configurations. In this work, multisegmented CoNi/Ni nanowires are synthesized for tailoring a periodic magnetic structure determined by the balance between magnetocrystalline and magnetostatic energies. High-resolution...

Membrane-disrupting iridium(iii) oligocationic organometallopeptides.

Chem Commun (Camb). 2016 Sep 21;52(73):11008-11. doi: 10.1039/c6cc05537k. Epub 2016 Aug 19.

A series of oligoarginine peptide derivatives containing cyclometallated iridium(iii) units display remarkable cytotoxicity, comparable to that of cisplatin. In vitro studies with unilamellar vesicles support a membrane-disrupting mechanism of action.

A designed DNA binding motif that recognizes extended sites and spans two adjacent major grooves.

PMID: 27252825
Chem Sci. 2016 May 01;7(5):3298-3303. doi: 10.1039/C6SC00045B. Epub 2016 Feb 05.

We report the rational design of a DNA-binding peptide construct composed of the DNA-contacting regions of two transcription factors (GCN4 and GAGA) linked through an AT-hook DNA anchor. The resulting chimera, which represents a new, non-natural DNA binding motif,...

Long-Term Effects of Prenatal Exposure to Undernutrition on Cannabinoid Receptor-Related Behaviors: Sex and Tissue-Specific Alterations in the mRNA Expression of Cannabinoid Receptors and Lipid Metabolic Regulators.

Frontiers in behavioral neuroscience

Ramírez-López MT, Arco R, Decara J, Vázquez M, Rivera P, Blanco RN, Alén F, Gómez de Heras R, Suárez J, Rodríguez de Fonseca F.

Maternal malnutrition causes long-lasting alterations in feeding behavior and energy homeostasis in offspring. It is still unknown whether both, the endocannabinoid (eCB) machinery and the lipid metabolism are implicated in long-term adaptive responses to fetal reprogramming caused by maternal...

Complete dataset for 2-treatment, 2-sequence, 2-period efavirenz bioequivalence study conducted with nightly dosing.

Data in brief
