Adrenocortical zonation, renewal, and remodeling.

Frontiers in endocrinology

Pihlajoki M, Dörner J, Cochran RS, Heikinheimo M, Wilson DB.
PMID: 25798129
Front Endocrinol (Lausanne). 2015 Mar 05;6:27. doi: 10.3389/fendo.2015.00027. eCollection 2015.

The adrenal cortex is divided into concentric zones. In humans the major cortical zones are the zona glomerulosa, zona fasciculata, and zona reticularis. The adrenal cortex is a dynamic organ in which senescent cells are replaced by newly differentiated...

Depopulation of Single-Phthalocyanine Molecular Orbitals upon Pyrrolic-Hydrogen Abstraction on Graphene.

ACS nano

Néel N, Lattelais M, Bocquet ML, Kröger J.
PMID: 26812093
ACS Nano. 2016 Feb 23;10(2):2010-6. doi: 10.1021/acsnano.5b06153. Epub 2016 Feb 01.

Single-molecule chemistry with a scanning tunneling microscope has preponderantly been performed on metal surfaces. The molecule-metal hybridization, however, is often detrimental to genuine molecular properties and obscures their changes upon chemical reactions. We used graphene on Ir(111) to reduce...

Superstructures and Electronic Properties of Manganese-Phthalocyanine Molecules on Au(110) from Submonolayer Coverage to Ultrathin Molecular Films.

Langmuir : the ACS journal of surfaces and colloids

Topyła M, Néel N, Kröger J.
PMID: 27322189
Langmuir. 2016 Jul 12;32(27):6843-50. doi: 10.1021/acs.langmuir.6b01529. Epub 2016 Jun 29.

The adsorption of manganese-phthalocyanine molecules on Au(110) was investigated using a low-temperature scanning tunneling microscope. A rich variety of commensurate superstructures was observed upon increasing the molecule coverage from submonolayers to ultrathin films. All structures were associated with reconstructions...

Spatially and temporally resolved temperature measurement in laser media.

Optics letters

Körner J, Yue F, Hein J, Kaluza MC.
PMID: 27244405
Opt Lett. 2016 Jun 01;41(11):2525-8. doi: 10.1364/OL.41.002525.

A technique to measure the spatially resolved temperature distribution in a laser medium is presented. It is based on the temperature dependence of the absorption cross section close to the zero-phonon line of the active medium. Since other materials...

Spectroscopic Line Shapes of Vibrational Quanta in the Presence of Molecular Resonances.

The journal of physical chemistry letters

Meierott S, Néel N, Kröger J.
PMID: 27280313
J Phys Chem Lett. 2016 Jul 07;7(13):2388-93. doi: 10.1021/acs.jpclett.6b00923. Epub 2016 Jun 14.

Line shapes of molecular vibrational quanta in inelastic electron tunneling spectroscopy may indicate the strength of electron-vibration coupling, the hybridization of the molecule with its environment, and the degree of vibrational damping by electron-hole pair excitation. Bare as well...

Modern Diagnostic Methods in Ewing's Sarcoma Family: Six Patients With Histologic Soft Tissue Tumors.

Molecular diagnosis : a journal devoted to the understanding of human disease through the clinical application of molecular biology

Hany MA, Adams V, Moos R, Betts DR, Niggli FK, Briner J.
PMID: 10462587
Mol Diagn. 1997 Mar;2(1):15-22. doi: 10.1054/MODI00200015.

Background: Soft tissue tumors often present a major diagnostic challenge for the pathologist. The correct diagnosis has important prognostic and therapeutic consequences. In recent years significant progress has been made in identifying characteristic chromosomal abnormalities associated with certain solid...

Temperature-dependent fermi gap opening in the c(6x4)-C60/Ag(100) two-dimensional superstructure.

Physical review letters

Cepek C, Vobornik I, Goldoni A, Magnano E, Selvaggi G, Kröger J, Panaccione G, Rossi G, Sancrotti M.
PMID: 11290117
Phys Rev Lett. 2001 Apr 02;86(14):3100-3. doi: 10.1103/PhysRevLett.86.3100.

High-resolution angle-integrated photoemission of one monolayer of C (60) chemisorbed on Ag(100) shows the reversible opening of a gap at the Fermi level at temperatures 25< or =T< or =300 K. The gap reaches a maximum value of approximately...

Variation of Isometric Response Force in the Rat.

Journal of motor behavior

Slifkin AB, Mitchell SH, Brener J.
PMID: 12529232
J Mot Behav. 1995 Dec;27(4):375-381. doi: 10.1080/00222895.1995.9941725.

Hungry, unrestrained rats (N = 7) were rewarded for pressing a response beam in excess of 11 different force requirements. Changes in peak force production as a function of peak force requirement were examined by analyses of the first...

Kinetics of organ specific metabolism of a bolus injection into the jejunum of glutamine, alpha-ketoglutarate, ornithine and ornithine - alpha-ketoglutarate.

Atom transfer and single-adatom contacts.

Physical review letters

Limot L, Kröger J, Berndt R, Garcia-Lekue A, Hofer WA.
PMID: 15903941

The point contact of a tunnel tip approaching towards Ag(111) and Cu(111) surfaces is investigated with a low temperature scanning tunneling microscope. A sharp jump to contact, random in nature, is observed in the conductance. After point contact, the...

Shock waves in rapid flows of dense granular materials: theoretical predictions and experimental results.
