Surrogate endpoints: a basis for a rational approach.

European journal of clinical pharmacology

Boissel JP, Collet JP, Moleur P, Haugh M.
PMID: 1425885
Eur J Clin Pharmacol. 1992;43(3):235-44. doi: 10.1007/BF02333016.

In clinical trials, the clinical endpoint is often replaced by an intermediate endpoint, known in some instances as a "surrogate" endpoint. The reasons for the substitution are often both practical and financial. At present, no theoretical basis or practical...

[Clinical trials in general practice. The telematics solution].

PMID: 2080485
Therapie. 1990 Nov-Dec;45(6):471-4.

Clinical trials with private practitioners pose a series of specific problems. Among them, the large number of investigators, the scarcity of time that each investigator can allocate to the study, may be eased by using computerized network. The telematic...

XRD monitoring of α self-irradiation in uranium-americium mixed oxides.

Inorganic chemistry

Horlait D, Lebreton F, Roussel P, Delahaye T.
PMID: 24266774
Inorg Chem. 2013 Dec 16;52(24):14196-204. doi: 10.1021/ic402124s. Epub 2013 Nov 22.

The structural evolution under (241)Am self-irradiation of U(1-x)Am(x)O(2±δ) transmutation fuels (with x ≤ 0.5) was studied by X-ray diffraction (XRD). Samples first underwent a preliminary heat treatment performed under a reducing atmosphere (Ar/H2(4%)) aiming to recover the previously accumulated...

Strong Reduction of Thermal Conductivity and Enhanced Thermoelectric Properties in CoSbS.

Scientific reports

Chmielowski R, Bhattacharya S, Jacob S, Péré D, Jacob A, Moriya K, Delatouche B, Roussel P, Madsen G, Dennler G.
PMID: 28425457
Sci Rep. 2017 Apr 20;7:46630. doi: 10.1038/srep46630.

In order to reduce the thermal conductivity of CoSbS, a newly developed thermoelectric semiconductor, we have aimed at intentionally induce atomic disorder in its structure. This endeavor was guided by Density Functional Theory(DFT) calculations which indicated that substituting sulfur...

3D Surface Reconstruction of Plant Seeds by Volume Carving: Performance and Accuracies.

Frontiers in plant science

Roussel J, Geiger F, Fischbach A, Jahnke S, Scharr H.
PMID: 27375628
Front Plant Sci. 2016 Jun 07;7:745. doi: 10.3389/fpls.2016.00745. eCollection 2016.

We describe a method for 3D reconstruction of plant seed surfaces, focusing on small seeds with diameters as small as 200 μm. The method considers robotized systems allowing single seed handling in order to rotate a single seed in...

BaCoO2.22: the most oxygen-deficient certified cubic perovskite.

Dalton transactions (Cambridge, England : 2003)

Mentré O, Iorgulescu M, Huvé M, Kabbour H, Renaut N, Daviero-Minaud S, Colis S, Roussel P.

Dalton Trans. 2015 Jun 21;44(23):10728-37. doi: 10.1039/c4dt03874f. Epub 2015 Feb 16.

The cubic BaCoO(∼2.2) was announced in the early 50's as the final product of high temperature self-reduction within the BaCoO(3-δ) series. However, apart from this report no clear characterization has been provided to date. Here, we confirm after the...

Bis(phenolate)amine-supported lanthanide borohydride complexes for styrene and trans-1,4-isoprene (co-)polymerisations.

Dalton transactions (Cambridge, England : 2003)

Bonnet F, Dyer HE, El Kinani Y, Dietz C, Roussel P, Bria M, Visseaux M, Zinck P, Mountford P.
PMID: 25997125
Dalton Trans. 2015 Jul 21;44(27):12312-25. doi: 10.1039/c5dt00252d.

New bis(phenolate)amine-supported neodymium borohydride complexes and their previously reported samarium analogues were tested as catalysts for the polymerisation of styrene and isoprene. Reaction of Na2O2N(L) (L = py, OMe, NMe2) with Nd(BH4)3(THF)3 afforded the borohydride complexes Nd(O2N(L))(BH4)(THF) (L =...

Gold(I)-Catalysed Asymmetric Hydroamination of Alkenes: A Silver- and Solvent-Dependent Enantiodivergent Reaction.

Chemistry (Weinheim an der Bergstrasse, Germany)

In the present study, we report the first silver-dependent enantiodivergent gold-catalysed reaction. The asymmetric intramolecular hydroamination of alkenes catalysed by the combination of a single chiral binuclear gold(I) chloride complex and silver perchlorate can afford both enantiomers of the...
