Optical pseudomotors for soft x-ray beamlines.

The Review of scientific instruments

Pedreira P, Sics I, Sorrentino A, Pereiro E, Aballe L, Foerster M, Pérez-Dieste V, Escudero C, Nicolas J.
PMID: 27250382
Rev Sci Instrum. 2016 May;87(5):052002. doi: 10.1063/1.4949339.

Optical elements of soft x-ray beamlines usually have motorized translations and rotations that allow for the fine alignment of the beamline. This is to steer the photon beam at some positions and to correct the focus on slits or...

Synthesis of Functionalized 1,4-Azaborinines by the Cyclization of Di-tert-butyliminoborane and Alkynes.

Journal of the American Chemical Society

Schäfer M, Beattie NA, Geetharani K, Schäfer J, Ewing WC, Krahfuß M, Hörl C, Dewhurst RD, Macgregor SA, Lambert C, Braunschweig H.
PMID: 27286231
J Am Chem Soc. 2016 Jul 06;138(26):8212-20. doi: 10.1021/jacs.6b04128. Epub 2016 Jun 27.

Di-tert-butyliminoborane is found to be a very useful synthon for the synthesis of a variety of functionalized 1,4-azaborinines by the Rh-mediated cyclization of iminoboranes with alkynes. The reactions proceed via [2 + 2] cycloaddition of iminoboranes and alkynes in...

Powerful Bispyridinylidene Organic Reducing Agents with Iminophosphorano π-Donor Substituents.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hanson SS, Richard NA, Dyker CA.
PMID: 25877958
Chemistry. 2015 May 26;21(22):8052-5. doi: 10.1002/chem.201500809. Epub 2015 Apr 15.

Four members of a new family of powerful bispyridinylidene organic reducing agents have been prepared, which exploit iminophosphorano (-N=PR3; R = Ph, Cy) π-donor substituents. Electrochemical studies show exceptionally high oxidation potentials, ranging from 1.30 to 1.51 V versus...

Social Environment Shapes the Speed of Cooperation.

Scientific reports

Nishi A, Christakis NA, Evans AM, O'Malley AJ, Rand DG.
PMID: 27435940
Sci Rep. 2016 Jul 20;6:29622. doi: 10.1038/srep29622.

Are cooperative decisions typically made more quickly or slowly than non-cooperative decisions? While this question has attracted considerable attention in recent years, most research has focused on one-shot interactions. Yet it is repeated interactions that characterize most important real-world...

A particular effect of sleep, but not pain or depression, on the blood-oxygen-level dependent response during working memory tasks in patients with chronic pain.

Journal of pain research

Elvemo NA, Landrø NI, Borchgrevink PC, Håberg AK.
PMID: 26185465
J Pain Res. 2015 Jul 07;8:335-46. doi: 10.2147/JPR.S83486. eCollection 2015.

BACKGROUND: Patients with chronic pain (CP) are often reported to have deficits in working memory. Pain impairs working memory, but so do depression and sleep problems, which are also common in CP. Depression has been linked to changes in...

Discovery of BMS-955176, a Second Generation HIV-1 Maturation Inhibitor with Broad Spectrum Antiviral Activity.

HIV-1 maturation inhibition (MI) has been clinically validated as an approach to the control of HIV-1 infection. However, identifying an MI with both broad polymorphic spectrum coverage and good oral exposure has been challenging. Herein, we describe the design,...

Association of hospital and physician case volumes with cardiac monitoring and cardiotoxicity during adjuvant trastuzumab treatment for breast cancer: a retrospective cohort study.

CMAJ open

Chin-Yee NJ, Yan AT, Kumachev A, Ko D, Earle C, Tomlinson G, Trudeau ME, Krahn M, Krzyzanowska M, Pal R, Brezden-Masley C, Gavura S, Lien K, Chan K.

BACKGROUND: Adjuvant trastuzumab is the standard of care for patients with HER2 overexpressing breast cancer, but use of trastuzumab may lead to cardiotoxicity. Our goal was to evaluate the relationship between hospital and physician case volume and cardiac outcomes...

Role of hydrogen-bonding and its interplay with octahedral tilting in CH3NH3PbI3.

Chemical communications (Cambridge, England)

Lee JH, Bristowe NC, Bristowe PD, Cheetham AK.
PMID: 25766075
Chem Commun (Camb). 2015 Apr 14;51(29):6434-7. doi: 10.1039/c5cc00979k.

First principles calculations on the hybrid perovskite CH3NH3PbI3 predict strong hydrogen-bonding which influences the structure and dynamics of the methylammonium cation and reveal its interaction with the tilting of the PbI6 octahedra. The calculated atomic coordinates are in excellent...

Chemical control of the viscoelastic properties of vinylogous urethane vitrimers.

Nature communications

Denissen W, Droesbeke M, Nicolaÿ R, Leibler L, Winne JM, Du Prez FE.
PMID: 28317893
Nat Commun. 2017 Mar 20;8:14857. doi: 10.1038/ncomms14857.

Vinylogous urethane based vitrimers are polymer networks that have the intrinsic property to undergo network rearrangements, stress relaxation and viscoelastic flow, mediated by rapid addition/elimination reactions of free chain end amines. Here we show that the covalent exchange kinetics...
