Electronic cooling via interlayer Coulomb coupling in multilayer epitaxial graphene.

Nature communications

Mihnev MT, Tolsma JR, Divin CJ, Sun D, Asgari R, Polini M, Berger C, de Heer WA, MacDonald AH, Norris TB.
PMID: 26399955
Nat Commun. 2015 Sep 24;6:8105. doi: 10.1038/ncomms9105.

In van der Waals bonded or rotationally disordered multilayer stacks of two-dimensional (2D) materials, the electronic states remain tightly confined within individual 2D layers. As a result, electron-phonon interactions occur primarily within layers and interlayer electrical conductivities are low....

Physical cryptographic verification of nuclear warheads.

Proceedings of the National Academy of Sciences of the United States of America

Kemp RS, Danagoulian A, Macdonald RR, Vavrek JR.
PMID: 27432959
Proc Natl Acad Sci U S A. 2016 Aug 02;113(31):8618-23. doi: 10.1073/pnas.1603916113. Epub 2016 Jul 18.

How does one prove a claim about a highly sensitive object such as a nuclear weapon without revealing information about the object? This paradox has challenged nuclear arms control for more than five decades. We present a mechanism in...

Structural Requirements and Docking Analysis of Amidine-Based Sphingosine Kinase 1 Inhibitors Containing Oxadiazoles.

ACS medicinal chemistry letters

Houck JD, Dawson TK, Kennedy AJ, Kharel Y, Naimon ND, Field SD, Lynch KR, Macdonald TL.
PMID: 27190598
ACS Med Chem Lett. 2016 Mar 01;7(5):487-92. doi: 10.1021/acsmedchemlett.6b00002. eCollection 2016 May 12.

Sphingosine 1-phosphate (S1P) is a potent growth-signaling lipid that has been implicated in cancer progression, inflammation, sickle cell disease, and fibrosis. Two sphingosine kinases (SphK1 and 2) are the source of S1P; thus, inhibitors of the SphKs have potential...

Separation of superficial and cerebral hemodynamics using a single distance time-domain NIRS measurement.

Biomedical optics express

Jelzow A, Wabnitz H, Tachtsidis I, Kirilina E, Brühl R, Macdonald R.
PMID: 24877009
Biomed Opt Express. 2014 Apr 10;5(5):1465-82. doi: 10.1364/BOE.5.001465. eCollection 2014 May 01.

In functional near-infrared spectroscopy (fNIRS) superficial hemodynamics can mask optical signals related to brain activity. We present a method to separate superficial and cerebral absorption changes based on the analysis of changes in moments of time-of-flight distributions and a...

Exercise training is an effective alternative to estrogen supplementation for improving glucose homeostasis in ovariectomized rats.

Physiological reports

MacDonald TL, Ritchie KL, Davies S, Hamilton MJ, Cervone DT, Dyck DJ.
PMID: 26603453
Physiol Rep. 2015 Nov;3(11). doi: 10.14814/phy2.12617. Epub 2015 Nov 24.

The irreversible loss of estrogen (specifically 17-β-estradiol; E2) compromises whole-body glucose tolerance in women. Hormone replacement therapy (HRT) is frequently prescribed to treat estrogen deficiency, but has several deleterious side effects. Exercise has been proposed as an HRT substitute,...

Longitudinal cerebellar diffusion tensor imaging changes in posterior fossa syndrome.

NeuroImage. Clinical

McEvoy SD, Lee A, Poliakov A, Friedman S, Shaw D, Browd SR, Ellenbogen RG, Ojemann JG, Mac Donald CL.
PMID: 27689022
Neuroimage Clin. 2016 Sep 09;12:582-590. doi: 10.1016/j.nicl.2016.09.007. eCollection 2016.

Posterior fossa syndrome is a severe transient loss of language that frequently complicates resection of tumors of the cerebellum. The associated pathophysiology and relevant anatomy to this language deficit remains controversial. We performed a retrospective analysis of all cerebellar...

Patient safety improvement interventions in children's surgery: A systematic review.

Journal of pediatric surgery

Macdonald AL, Sevdalis N.
PMID: 27717565
J Pediatr Surg. 2017 Mar;52(3):504-511. doi: 10.1016/j.jpedsurg.2016.09.058. Epub 2016 Sep 24.

BACKGROUND: Adult surgical patient safety literature is plentiful; however, there is a disproportionate paucity of published safety work in the children's surgical literature. We sought to systematically evaluate the nature and quality of patient safety evidence pertaining to pediatric...

Detection of titanium oxide in the atmosphere of a hot Jupiter.

Nature

Sedaghati E, Boffin HMJ, MacDonald RJ, Gandhi S, Madhusudhan N, Gibson NP, Oshagh M, Claret A, Rauer H.

As an exoplanet transits its host star, some of the light from the star is absorbed by the atoms and molecules in the planet's atmosphere, causing the planet to seem bigger; plotting the planet's observed size as a function...
