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].

Therapie

Boissel JP, Alamercery Y, Collet JP, Luciani J, Leizorovicz A.
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...

Dynamic granularity of imaging systems.

The Review of scientific instruments

Geissel M, Smith IC, Shores JE, Porter JL.
PMID: 26628138
Rev Sci Instrum. 2015 Nov;86(11):113701. doi: 10.1063/1.4934543.

Imaging systems that include a specific source, imaging concept, geometry, and detector have unique properties such as signal-to-noise ratio, dynamic range, spatial resolution, distortions, and contrast. Some of these properties are inherently connected, particularly dynamic range and spatial resolution....

What benefit could be derived from on-line adaptive prostate radiotherapy using rectal diameter as a predictor of motion?.

Journal of medical physics

Oates R, Gill S, Foroudi F, Joon ML, Schneider M, Bressel M, Kron T.
PMID: 26150683
J Med Phys. 2015 Jan-Mar;40(1):18-23. doi: 10.4103/0971-6203.152237.

This study investigated a relationship between rectum diameter and prostate motion during treatment with a view to reducing planning target volume (PTV) margins for an adaptive protocol. One hundred and ninety-four cone-beam computed tomography (CBCT) images of 10 patients...

X-ray microtomography provides first data about the feeding behaviour of an endangered lizard, the Montserrat galliwasp (Diploglossus montisserrati).

Royal Society open science

Bochaton C, Boistel R, Charles L.
PMID: 27019732
R Soc Open Sci. 2015 Dec 23;2(12):150461. doi: 10.1098/rsos.150461. eCollection 2015 Dec.

Reporting the diet of recently extinct or very rare taxa, only known by a few museum specimens, is challenging. This study uses X-ray microtomography, a non-destructive investigation method, to obtain the first data about feeding behaviours in the Montserrat...

Charge-exchange-induced two-electron satellite transitions from autoionizing levels in dense plasmas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Rosmej FB, Griem HR, Elton RC, Jacobs VL, Cobble JA, Faenov AY, Pikuz TA, Geissel M, Hoffmann DH, Süss W, Uskov DB, Shevelko VP, Mancini RC.
PMID: 12513602
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Nov;66(5):056402. doi: 10.1103/PhysRevE.66.056402. Epub 2002 Nov 11.

Order-of-magnitude anomalously high intensities for two-electron (dielectronic) satellite transitions, originating from the He-like 2s(2) 1S0 and Li-like 1s2s(2) (2)S(1/2) autoionizing states of silicon, have been observed in dense laser-produced plasmas at different laboratories. Spatially resolved, high-resolution spectra and plasma...

Gas phase infrared spectroscopy of selectively prepared ions.

Physical review letters

Lemaire J, Boissel P, Heninger M, Mauclaire G, Bellec G, Mestdagh H, Simon A, Le Caer S, Ortega JM, Glotin F, Maitre P.
PMID: 12513202
Phys Rev Lett. 2002 Dec 30;89(27):273002. doi: 10.1103/PhysRevLett.89.273002. Epub 2002 Dec 18.

The first example of direct structural characterization of polyaromatic ions by coupling a Fourier transform ion cyclotron resonance mass spectrometer with an infrared free-electron laser is presented. Measurement of the IR spectra of selectively prepared ionic reactive intermediates is...

Mixed transfer function and transport of intensity approach for phase retrieval in the Fresnel region.

Optics letters

Guigay JP, Langer M, Boistel R, Cloetens P.
PMID: 17572724
Opt Lett. 2007 Jun 15;32(12):1617-9. doi: 10.1364/ol.32.001617.

We present a method for phase retrieval in propagation-based x-ray imaging, based on the contrast transfer and transport of intensity equation approaches. We show that the contrast transfer model does not coincide with the transport of intensity in the...

Complications to optical measurements using a laser with an unstable resonator: a case study on laser-induced incandescence of soot.

Applied optics

Dansson MA, Boisselle M, Linne MA, Michelsen HA.
PMID: 18026549
Appl Opt. 2007 Nov 20;46(33):8095-103. doi: 10.1364/ao.46.008095.

Temporal behavior of pulses from a Q-switched Nd:YAG laser with an unstable resonator can vary significantly with radial position in the beam. Our laser provides pulses with position-dependent durations spanning 8-11.5 ns at 1064 nm and 7-10 ns at...
