Hossain A, Phelps J, Agarwal A, Sanz E, Mahadevan M.
PMID: 27441045
Int J Fertil Steril. 2016 Jul-Sep;10(2):141-7. doi: 10.22074/ijfs.2016.4956. Epub 2016 Jun 01.

The Society for Assisted Reproductive Technology (SART) method of embryo grad- ing is unique, simple, and widely practiced, and its use has been mandatory for SART membership programs since 2010. Developed by SART in 2006, the current embryo grading...

Adsorption of probe molecules in pillared interlayered clays: experiment and computer simulation.

The Journal of chemical physics

Gallardo A, Guil JM, Lomba E, Almarza NG, Khatib SJ, Cabrillo C, Sanz A, Pires J.
PMID: 24929408
J Chem Phys. 2014 Jun 14;140(22):224701. doi: 10.1063/1.4880962.

In this paper we investigate the adsorption of various probe molecules in order to characterize the porous structure of a series of pillared interlayered clays (PILC). To that aim, volumetric and microcalorimetric adsorption experiments were performed on various Zr...

Beilstein J Org Chem. 2013 Oct 29;9:2242-9. doi: 10.3762/bjoc.9.263. eCollection 2013.

The cyclization of o-(alkynyl)-3-(methylbut-2-enyl)benzenes, 1,6-enynes having a condensed aromatic ring at C3-C4 positions, has been studied under the catalysis of cationic gold(I) complexes. The selective 6-endo-dig mode of cyclization observed for the 7-substituted substrates in the presence of water...

Meiotic pairing and alpha-amylase phenotype in a 5B/5R(m) Triticum aestivum - Secale montanum translocation line in common wheat.

PMID: 24240757
Theor Appl Genet. 1986 Nov;73(1):122-8. doi: 10.1007/BF00273728.

A 5BS/5R(m)S translocation chromosome spontaneously recovered from a 'Chinese Spring' - Secale montanum wheat-rye telocentric 5R(m)S addition line has been identified and cytologically studied using C-banding in somatic and meiotic cells. Analysis of the translocated chromosome showed that a...

Gold(I)-catalyzed cycloisomerizations and alkoxycyclizations of ortho-(alkynyl)styrenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Sanjuán AM, Rashid MA, García-García P, Martínez-Cuezva A, Fernández-Rodríguez MA, Rodríguez F, Sanz R.
PMID: 25557166
Chemistry. 2015 Feb 09;21(7):3042-52. doi: 10.1002/chem.201405789. Epub 2014 Dec 29.

Indenes and related polycyclic structures have been efficiently synthesized by gold(I)-catalyzed cycloisomerizations of appropriate ortho-(alkynyl)styrenes. Disubstitution at the terminal position of the olefin was demonstrated to be essential to obtain products originating from a formal 5-endo-dig cyclization. Interestingly, a...

Origin of constant loss in ionic conductors.

Physical review letters

León C, Rivera A, Várez A, Sanz J, Santamaria J, Ngai KL.
PMID: 11178063
Phys Rev Lett. 2001 Feb 12;86(7):1279-82. doi: 10.1103/PhysRevLett.86.1279.

We have analyzed the constant loss contribution to the ac conductivity in the frequency range 10 Hz-1 MHz and temperatures down to 8 K, for two Li ionic conductors, one crystalline (Li(0.18)La(0.61)TiO(3)) and the other glassy (61SiO(2);35Li(2)O.3Al(2)O3.P(2)O(5)). As temperature...

An Efficient and Simple Entry to N-Substituted beta-Enamino Acid Derivatives from 2-Alkyl-2-oxazolines and 2-Alkyl-2-thiazolines.

Fañanás FJ, Granados A, Sanz R, Ignacio JM, Barluenga J.
PMID: 11486966
Chemistry. 2001 Jul 02;7(13):2896-907. doi: 10.1002/1521-3765(20010702)7:13<2896::aid-chem2896>3.0.co;2-r.

Bis(2-lithioallyl)amines derived from bis(2-bromoallyl)amines undergo intramolecular carbometallation of a lithiated double bond, giving dilithiated dihydropyrroles. The cyclizations are promoted by N,N,N',N'-tetramethylethylenediamine (TMEDA). Reaction of these intermediates with electrophiles allows the preparation of some new fused and nonfused five-membered functionalized...
