PMID: 27995163
Data Brief. 2016 Dec 07;10:277-282. doi: 10.1016/j.dib.2016.11.094. eCollection 2017 Feb.

The data presented in this article is related to the research paper entitled "The long arm of childhood circumstances on health in old age: Evidence from SHARELIFE" (E. Pakpahan, R. Hoffmann, H. Kröger, 2016) [1]. It presents the distribution...

Evaluation of a newly designed flow diverter for the treatment of intracranial aneurysms in an elastase-induced aneurysm model, in New Zealand white rabbits.

Neuroradiology. 2013 Nov 14; doi: 10.1007/s00234-013-1296-9. Epub 2013 Nov 14.

INTRODUCTION: In this study, we analyzed angiographic and histologic aneurysm occlusion of a newly designed flow-diverting device. Visibility and flexibility, as well as occlusions of side branches and neointimal proliferation were also evaluated.METHODS: Aneurysms were induced in 18 New...

Diagnosis of Knee Osteochondral Lesions With Ultrasound Imaging.

Arthroscopy techniques

Penttilä P, Liukkonen J, Joukainen A, Virén T, Jurvelin JS, Töyräs J, Kröger H.
PMID: 26697300
Arthrosc Tech. 2015 Sep 14;4(5):e429-33. doi: 10.1016/j.eats.2015.04.002. eCollection 2015 Oct.

Evaluation of articular cartilage and subchondral bone is essential in the diagnosis of joint diseases and injuries. Interobserver and intraobserver reproducibilities of arthroscopic grading are only poor to moderate. Thus, for quantitative and objective evaluation of cartilage and subchondral...

Closed path integrals and the quantum action.

Physical review letters

Jirari H, Kröger H, Luo XQ, Moriarty KJ, Rubin SG.
PMID: 11177788
Phys Rev Lett. 2001 Jan 08;86(2):187-91. doi: 10.1103/PhysRevLett.86.187.

We suggest a closed form expression for the path integral of quantum transition amplitudes. We introduce a quantum action with parameters different from the classical action. We present numerical results for the harmonic oscillator with weak perturbation, the quartic...

Multimode-photochromism based on strongly coupled dihydroazulene and diarylethene.

Chemistry (Weinheim an der Bergstrasse, Germany)

Mrozek T, Görner H, Daub J.
PMID: 11303863
Chemistry. 2001 Mar 02;7(5):1028-40. doi: 10.1002/1521-3765(20010302)7:5<1028::aid-chem1028>3.0.co;2-7.

Synthesis and photophysical/photochemical investigations of 1,8a-dihydro-2,3-bis(2,5-dimethy-3-thienyl)-azulene-1,1-dicarbonitrile (1A) and 1,8a-dihydro-2,3-diphenylazulene-1,1-dicarbonitrile (2A) are reported. The photoprocesses and thermal reactions of systems 1 and 2 were studied by time-resolved and steady-state techniques under various conditions. The dihydroazulene (DHA)-dithienylethene (DTE) conjugate 1A is...

Photoreduction of 9,10-anthraquinone derivatives: transient spectroscopy and effects of alcohols and amines on reactivity in solution.

Photochemistry and photobiology

Görner H.
PMID: 12785056
Photochem Photobiol. 2003 Feb;77(2):171-9. doi: 10.1562/0031-8655(2003)077<0171:poadts>2.0.co;2.

The photoreduction of 9,10-anthraquinone (AQ), the 2-methyl, 2-ethyl, 2,3-dimethyl, 1,4-difluoro, 1-chloro and 1,8-dichloro derivatives as well as 1,4,4a,9a-tetrahydroanthraquinone, 1,2-benzanthraquinone and 6,13-pentacenequinone in nonaqueous solution at room temperature was studied by time-resolved UV-visible spectroscopy. Upon 308 nm excitation of AQ...

The development of new monometallic bifunctional catalysts with Lewis acid and Lewis base properties, and their application in asymmetric cyanation reactions.

Chemistry (Weinheim an der Bergstrasse, Germany)

Gröger H.
PMID: 11822424
Chemistry. 2001 Dec 17;7(24):5246-51. doi: 10.1002/1521-3765(20011217)7:24<5246::aid-chem5246>3.0.co;2-o.

Bifunctional catalysts can drastically improve the efficiency of asymmetric processes with respect to enantioselectivity and/or conversion rate. A new type of chiral bifunctional catalyst has been developed recently in the Shibasaki group that contains both Lewis acid and Lewis...

Refractometry of organosilica microspheres.

Applied optics

Seet KY, Vogel R, Nieminen TA, Knöner G, Rubinsztein-Dunlop H, Trau M, Zvyagin AV.

Appl Opt. 2007 Mar 20;46(9):1554-61. doi: 10.1364/ao.46.001554.

The refractive index of novel organosilica (nano/micro) material is determined using two methods. The first method is based on analysis of optical extinction efficiency of organosilica beads versus wavelength, which is obtained by a standard laboratory spectrometer. The second...
