Prehospital Management of Acute Stroke in Rural versus Urban Responders.

Journal of neurosciences in rural practice

Hansen G, Bal S, Schellenberg KL, Alcock S, Ghrooda E.
PMID: 28936069
J Neurosci Rural Pract. 2017 Aug;8:S33-S36. doi: 10.4103/jnrp.jnrp_2_17.

OBJECTIVE: Stroke guideline compliance of rural Canadian prehospital emergency medical services (EMS) care in acute stroke is unknown. In this quality assurance study, we sought to compare rural and urban care by prehospital EMS evaluation/management indicators from patients assessed...

A practicable real-space measure and visualization of static electron-correlation effects.

Angewandte Chemie (International ed. in English)

Grimme S, Hansen A.
PMID: 25882895
Angew Chem Int Ed Engl. 2015 Oct 12;54(42):12308-13. doi: 10.1002/anie.201501887. Epub 2015 Apr 16.

The inclusion of dynamical and static electron correlation (SEC) is mandatory for accurate quantum chemistry (QC). SEC is particularly difficult to calculate and hence a qualitative understanding is important to judge the applicability of approximate QC methods. Existing scalar...

Adolescent Substance Use & Psychopathology: Interactive Effects of Cortisol Reactivity and Emotion Regulation.

Cognitive therapy and research

Poon JA, Turpyn CC, Hansen A, Jacangelo J, Chaplin TM.
PMID: 27330232
Cognit Ther Res. 2016 Jun;40(3):368-380. doi: 10.1007/s10608-015-9729-x. Epub 2015 Oct 28.

How are emotional processes associated with the increased rates of substance use and psychological disorders commonly observed during adolescence? An index of emotion-related physiological arousal-cortisol reactivity-and subjective emotion regulation have both been

Impact of incorrect tissue classification in Dixon-based MR-AC: fat-water tissue inversion.

EJNMMI physics

Ladefoged CN, Hansen AE, Keller SH, Holm S, Law I, Beyer T, Højgaard L, Kjær A, Andersen FL.
PMID: 26501459
EJNMMI Phys. 2014 Dec;1(1):101. doi: 10.1186/s40658-014-0101-0. Epub 2014 Dec 14.

BACKGROUND: The current MR-based attenuation correction (AC) used in combined PET/MR systems computes a Dixon attenuation map (MR-ACDixon) based on fat and water images derived from in- and opposed-phase MRI. We observed an occasional fat/water inversion in MR-ACDixon. The...

Highly efficient single-pass sum frequency generation by cascaded nonlinear crystals.

Optics letters

Hansen AK, Andersen PE, Jensen OB, Sumpf B, Erbert G, Petersen PM.
PMID: 26625042
Opt Lett. 2015 Dec 01;40(23):5526-9. doi: 10.1364/OL.40.005526.

The cascading of nonlinear crystals has been established as a simple method to greatly increase the conversion efficiency of single-pass second-harmonic generation compared to a single-crystal scheme. Here, we show for the first time that the technique can be...

Feasibility of simultaneous PET/MR in diet-induced atherosclerotic minipig: a pilot study for translational imaging.

American journal of nuclear medicine and molecular imaging

Pedersen SF, Ludvigsen TP, Johannesen HH, Löfgren J, Ripa RS, Hansen AE, Ettrup AJ, Christoffersen BØ, Pedersen HD, Olsen LH, Højgaard L, Kjær A.
PMID: 25143863
Am J Nucl Med Mol Imaging. 2014 Aug 15;4(5):448-58. eCollection 2014.

Novel hybrid 18-fluoro-deoxy-D-glucose ((18)F-FDG) based positron emission tomography (PET) and magnetic resonance imaging (MRI) has shown promise for characterization of atherosclerotic plaques clinically. The purpose of this study was to evaluate the method in a pre-clinical model of diet-induced...

Authenticity of raspberry flavor in food products using SPME-chiral-GC-MS.

Food science & nutrition

Hansen AM, Frandsen HL, Fromberg A.
PMID: 27247764
Food Sci Nutr. 2015 Oct 26;4(3):348-54. doi: 10.1002/fsn3.296. eCollection 2016 May.

A fast and simple method for authenticating raspberry flavors from food products was developed. The two enantiomers of the compound (E)-α-ionone from raspberry flavor were separated on a chiral gas chromatographic column. Based on the ratio of these two...

Hydrosilylation of ketones, imines and nitriles catalysed by electrophilic phosphonium cations: functional group selectivity and mechanistic considerations.

Chemistry (Weinheim an der Bergstrasse, Germany)

Pérez M, Qu ZW, Caputo CB, Podgorny V, Hounjet LJ, Hansen A, Dobrovetsky R, Grimme S, Stephan DW.
PMID: 25758303
Chemistry. 2015 Apr 20;21(17):6491-500. doi: 10.1002/chem.201406356. Epub 2015 Mar 10.

The electrophilic phosphonium salt, [(C6 F5 )3 PF][B(C6 F5 )4 ], catalyses the efficient hydrosilylation of ketones, imines and nitriles at room temperature. In the presence of this catalyst, adding one equivalent of hydrosilane to a nitrile yields a...

PP039. ETK/BMX and renin-angiotensin system (RAS) components are differentially expressed in renal tissue in both normal and preeclamptic pregnancy.

Pregnancy hypertension

INTRODUCTION: Renal ETK/BMX activity is reduced in preeclampsia. Systemic RAS has been studied in preeclampsia; the renal RAS has not. None of the proteins in either pathway have previously been located in renal tissue from human pregnancy.OBJECTIVES: To determine...
