Regioselective palladium-catalyzed ring-opening reactions of C1-substituted oxabicyclo[2,2,1]hepta-2,5-diene-2,3-dicarboxylates.

Beilstein journal of organic chemistry

Edmunds M, Raheem MA, Boutin R, Tait K, Tam W.
PMID: 26977182
Beilstein J Org Chem. 2016 Feb 09;12:239-44. doi: 10.3762/bjoc.12.25. eCollection 2016.

Palladium-catalyzed ring-opening reactions of C1 substituted 7-oxanorbornadiene derivatives with aryl iodides were investigated. The optimal conditions for this reaction were found to be PdCl2(PPh3)2, ZnCl2, Et3N and Zn in THF. Both steric and electronic factors played a role in...

Modality-specific organization in the representation of sensorimotor sequences.

Frontiers in psychology

Boutin A, Massen C, Heuer H.
PMID: 24376432
Front Psychol. 2013 Dec 11;4:937. doi: 10.3389/fpsyg.2013.00937. eCollection 2013.

Sensorimotor representations of movement sequences are hierarchically organized. Here we test the effects of different stimulus modalities on such organizations. In the visual group, participants responded to a repeated sequence of visually presented stimuli by depressing spatially compatible keys...

The Coupled Bio-Chemo-Electro-Mechanical Behavior of Glucose Exposed Arterial Elastin.

Journal of physics D: Applied physics

Zhang Y, Li J, Boutis GS.
PMID: 28989186
J Phys D Appl Phys. 2017;50. doi: 10.1088/1361-6463/aa5c55. Epub 2017 Mar 02.

Elastin, the principle protein component of the elastic fiber, is a critical extracellular matrix (ECM) component of the arterial wall providing structural resilience and biological signaling essential in vascular morphogenesis and maintenance of mechanical homeostasis. Pathogenesis of many cardiovascular...

Maternal inhaled fluticasone propionate intake during pregnancy is detected in neonatal cord blood.

Bioanalysis

Battista MC, Boutin M, Venne P, Blais L, Bérard A, Lacroix M, Patenaude J, Guillemette L, Cossette B, Hivert MF, Auray-Blais C.
PMID: 27349687
Bioanalysis. 2016 Jul;8(14):1441-1450. doi: 10.4155/bio-2016-0065. Epub 2016 Jun 28.

BACKGROUND: Despite recommendations to use inhaled corticosteroids as treatment to control asthma during pregnancy, it is unknown whether inhaled fluticasone propionate (FP) reaches the fetus. Results & methodology: We collected maternal blood on the morning following delivery. FP was...

Investigating the Pressure-Induced Amorphization of Zeolitic Imidazolate Framework ZIF-8: Mechanical Instability Due to Shear Mode Softening.

The journal of physical chemistry letters

Ortiz AU, Boutin A, Fuchs AH, Coudert FX.
PMID: 26283122
J Phys Chem Lett. 2013 Jun 06;4(11):1861-5. doi: 10.1021/jz400880p. Epub 2013 May 20.

We provide the first molecular dynamics study of the mechanical instability that is the cause of pressure-induced amorphization of zeolitic imidazolate framework ZIF-8. By measuring the elastic constants of ZIF-8 up to the amorphization pressure, we show that the...

Experimental moose reduction lowers wolf density and stops decline of endangered caribou.

PeerJ

Serrouya R, McLellan BN, van Oort H, Mowat G, Boutin S.
PMID: 28875080
PeerJ. 2017 Aug 29;5:e3736. doi: 10.7717/peerj.3736. eCollection 2017.

The expansion of moose into southern British Columbia caused the decline and extirpation of woodland caribou due to their shared predators, a process commonly referred to as apparent competition. Using an adaptive management experiment, we tested the hypothesis that...

Producing undistorted acoustic sine waves.

The Journal of the Acoustical Society of America

Boutin H, Smith J, Wolfe J.
PMID: 25234964
J Acoust Soc Am. 2014 Apr;135(4):1665-7. doi: 10.1121/1.4868374.

A simple digital method is described that can produce an undistorted acoustic sine wave using an amplifier and loudspeaker having considerable intrinsic distortion, a common situation at low frequencies and high power. The method involves, first, using a pure...

Impact of food and predation on the snowshoe hare cycle.

Science (New York, N.Y.)

Krebs CJ, Boutin S, Boonstra R, Sinclair AR, Smith JN, Dale MR, Martin K, Turkington R.
PMID: 17755536
Science. 1995 Aug 25;269(5227):1112-5. doi: 10.1126/science.269.5227.1112.

Snowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8 years in the Yukon. Two blocks of forest...

[Submitting studies without significant results].

Presse medicale (Paris, France : 1983)

Texier G, Meynard JB, Michel R, Migliani R, Boutin JP.
PMID: 17287106
Presse Med. 2007 Mar;36(3):541-50. doi: 10.1016/j.lpm.2007.01.015. Epub 2007 Feb 06.

When a study finds that no exposure factor or therapy is significantly related to a given effect, researchers legitimately wonder if the results should be submitted for publication and to what journal. Clinical trials that report significant associations have...

Finite pulse width artifact suppression in spin-1 quadrupolar echo spectra by phase cycling.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Mananga ES, Rumala YS, Boutis GS.
