Science and technology of advanced materials

Sebald G, Nakano M, Lallart M, Tian T, Diguet G, Cavaille JY.
PMID: 29152013
Sci Technol Adv Mater. 2017 Oct 13;18(1):766-778. doi: 10.1080/14686996.2017.1377590. eCollection 2017.

Magneto-rheological (MR) elastomers contain micro-/nano-sized ferromagnetic particles dispersed in a soft elastomer matrix, and their rheological properties (storage and loss moduli) exhibit a significant dependence on the application of a magnetic field (namely MR effect). Conversely, it is reported...

Enantioselective Synthesis of 6,6-Disubstituted Pentafulvenes Containing a Chiral Pendant Hydroxy Group.

Chemistry (Weinheim an der Bergstrasse, Germany)

Nouch R, Cini M, Magre M, Abid M, Diéguez M, Pàmies O, Woodward S, Lewis W.
PMID: 29083067
Chemistry. 2017 Dec 06;23(68):17195-17198. doi: 10.1002/chem.201704247. Epub 2017 Nov 20.

Simple enantioselective synthesis of 6,6-disubstituted pentafulvenes bearing chiral pendant hydroxy groups are attained by cascade reactivity using commercially available proline-based organocatalysts. Condensation of cyclopentadiene with the acetyl function of a 1,2-formylacetophenone, followed by cyclization of a resulting fulvene-stabilized carbanion...

Mol Metab. 2016 Feb 10;5(4):271-282. doi: 10.1016/j.molmet.2016.01.008. eCollection 2016 Apr.

OBJECTIVE: Classically, metabolic effects of thyroid hormones (THs) have been considered to be peripherally mediated, i.e. different tissues in the body respond directly to thyroid hormones with an increased metabolism. An alternative view is that the metabolic effects are...

Chiral phosphine-phosphite ligands in the highly enantioselective rhodium-catalyzed asymmetric hydrogenation.

The Journal of organic chemistry

Deerenberg S, Pàmies O, Diéguez M, Claver C, Kamer PC, van Leeuwen PW.
PMID: 11701013
J Org Chem. 2001 Nov 16;66(23):7626-31. doi: 10.1021/jo015705d.

We have investigated a series of enantiopure phosphine-phosphite ligands (P(1)-P(2) = ligands 1-4) in the rhodium-catalyzed asymmetric hydrogenation reaction. Intermediate [Rh(P(1)-P(2))(cod)]BF(4) and [Rh(P(1)-P(2))(5)]BF(4) complexes (cod = 1,5-cyclooctadiene; 5 = methyl acetamidoacrylate ester) were observed by (31)P[(1)H] NMR. The [Rh(P(1)-P(2))(cod)]BF(4)...

Schnitzler syndrome: a case study.

Journal of investigational allergology & clinical immunology

Sánchez G, Añó M, García-Avilés C, Diéguez I.
PMID: 10780799
J Investig Allergol Clin Immunol. 2000 Jan-Feb;10(1):41-3.

Schnitzler syndrome is a clinical entity of unknown etiopathogenesis and is an unusual cause of chronic urticaria. It is characterized by the presentation of a monoclonal band, especially IgM, as well as fever, asthenia and arthralgia. We present the...

Wannier-based definition of layer polarizations in perovskite superlattices.

Physical review letters

Wu X, Diéguez O, Rabe KM, Vanderbilt D.
PMID: 17025854
Phys Rev Lett. 2006 Sep 08;97(10):107602. doi: 10.1103/PhysRevLett.97.107602. Epub 2006 Sep 08.

In insulators, the method of Marzari and Vanderbilt [Phys. Rev. B 56, 12 847 (1997)] can be used to generate maximally localized Wannier functions whose centers are related to the electronic polarization. In the case of layered insulators, this...

The influence of serum cortisol levels on growth hormone responsiveness to GH-releasing hormone plus GH-releasing peptide-6 in patients with hypocortisolism.

Differential effects of direct and indirectly acting cholinergic agonists on growth hormone release in man, and lack of effect on cortisol secretion.

Journal of neuroendocrinology

Casanueva FF, Villanueva L, Cordido F, Diaz Y, Cabranes JA, Spiegel R, Dieguez C.
PMID: 19210431
J Neuroendocrinol. 1989 Oct 01;1(5):379-82. doi: 10.1111/j.1365-2826.1989.tb00132.x.

Abstract Acetylcholine plays a key role in the modulation of growth hormone secretion. In fact, growth hormone release after provocative stimuli is blocked by muscarinic cholinergic antagonists, and conversely, indirect cholinergic agonists potentiate growth hormone secretion. To further understand...
