Six1 is down-regulated in end-stage human dilated cardiomyopathy independently of Ezh2.

ESC heart failure

Tschirner A, Palus S, Hetzer R, Meyer R, Anker SD, Springer J.
PMID: 27668088
ESC Heart Fail. 2014 Dec;1(2):154-159. doi: 10.1002/ehf2.12017. Epub 2015 Jan 22.

BACKGROUND: Recently, it was shown that a knock-out (KO) of the polycomb histone methyltransferase Ezh2 leads to cardiac hypertrophy in mice, which was driven by the homeodomain transcription factor Six1. Here, we analyzed the expression of Six1 and its...

New insight into microgel-stabilized emulsions using transmission X-ray microscopy: nonuniform deformation and arrangement of microgels at liquid interfaces.

Langmuir : the ACS journal of surfaces and colloids

Geisel K, Henzler K, Guttmann P, Richtering W.
PMID: 25496214
Langmuir. 2015 Jan 13;31(1):83-9. doi: 10.1021/la503959n. Epub 2014 Dec 23.

Microgel-covered interfaces, e.g., in emulsions, have attracted much interest lately. Different imaging techniques have been used to image these interfaces, either flat or curved, to investigate their properties and appearance. Techniques such as cryogenic scanning electron microscopy (cryo-SEM) and...

Quantifying non-ergodic dynamics of force-free granular gases.

Physical chemistry chemical physics : PCCP

Bodrova A, Chechkin AV, Cherstvy AG, Metzler R.
PMID: 26252559
Phys Chem Chem Phys. 2015 Sep 14;17(34):21791-8. doi: 10.1039/c5cp02824h. Epub 2015 Aug 07.

Brownian motion is ergodic in the Boltzmann-Khinchin sense that long time averages of physical observables such as the mean squared displacement provide the same information as the corresponding ensemble average, even at out-of-equilibrium conditions. This property is the fundamental...

Myocardial recovery during mechanical circulatory support: cellular, molecular, genomic and organ levels.

Heart, lung and vessels

Dandel M, Hetzer R.
PMID: 26157737
Heart Lung Vessel. 2015;7(2):110-20.

Mechanical circulatory support is a life-saving therapy that will become either a bridge-to-transplantation or definitive therapy if heart transplantation is not possible. Failing hearts supported by a ventricular assist device  were often found to recover at molecular and cellular...

Autonomic Function is Associated with Fitness Level in HIV-Infected Individuals.

Jacobs journal of AIDS/HIV

Kocher MH, Hetzler RK, Shikuma CM, Kimura IF, Stickley CD, Lindsey RA, Nakamoto BK, Chow DC.
PMID: 26213714
Jacobs J AIDS HIV. 2015 Jun;1(1).

BACKGROUND: Cardiovascular fitness can improve autonomic function (AF) in human immunodeficiency virus (HIV)-infected individuals.METHODS: Cross-sectional study investigating relationship between AF and cardiovascular fitness in HIV+ individuals on antiretroviral therapy. Participants' (n=29) maximal oxygen consumption (VORESULTS: Median VOCONCLUSION: A positive...

Aging scaled Brownian motion.

Physical review. E, Statistical, nonlinear, and soft matter physics

Safdari H, Chechkin AV, Jafari GR, Metzler R.
PMID: 25974439
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Apr;91(4):042107. doi: 10.1103/PhysRevE.91.042107. Epub 2015 Apr 07.

Scaled Brownian motion (SBM) is widely used to model anomalous diffusion of passive tracers in complex and biological systems. It is a highly nonstationary process governed by the Langevin equation for Brownian motion, however, with a power-law time dependence...

Investigation of reactions between trace gases and functional CuO nanospheres and octahedrons using NEXAFS-TXM imaging.

Scientific reports

Henzler K, Heilemann A, Kneer J, Guttmann P, Jia H, Bartsch E, Lu Y, Palzer S.
PMID: 26631608
Sci Rep. 2015 Dec 03;5:17729. doi: 10.1038/srep17729.

In order to take full advantage of novel functional materials in the next generation of sensorial devices scalable processes for their fabrication and utilization are of great importance. Also understanding the processes lending the properties to those materials is...

Wall motion assessment by tissue Doppler imaging after heart transplantation: timing of endomyocardial biopsies and facilitation of therapeutic decisions during acute cardiac rejection.

The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation

Jamming transitions and avalanches in the game of Dots-and-Boxes.

Physical review. E, Statistical, nonlinear, and soft matter physics

Metzler R, Engel A.
PMID: 12188784
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Jun;65(6):066108. doi: 10.1103/PhysRevE.65.066108. Epub 2002 Jun 14.

We study the game of Dots-and-Boxes from a statistical point of view. The early game can be treated as a case of random sequential adsorption, with a jamming transition that marks the beginning of the end game. We derive...

Tight and loose shapes in flat entangled dense polymers.

The European physical journal. E, Soft matter

Hanke A, Metzler R, Dommersnes PG, Kantor Y, Kardar M.
PMID: 15007670
Eur Phys J E Soft Matter. 2003 Oct;12(2):347-354. doi: 10.1140/epje/i2003-10067-9.

We investigate the effects of topological constraints (entanglements) on two-dimensional polymer loops in the dense phase, and at the collapse transition (theta-point). Previous studies have shown that in the dilute phase the entangled region becomes tight, and is thus...
