Front Immunol. 2017 Aug 16;8:976. doi: 10.3389/fimmu.2017.00976. eCollection 2017.

High titer autoantibodies produced by B lymphocytes are clinically important features of many common autoimmune diseases. APECED patients with deficient autoimmune regulator (AIRE) gene collectively display a broad repertoire of high titer autoantibodies, including some which are pathognomonic for...

PMID: 26488340
Nanoscale. 2015 Nov 21;7(43):18337-42. doi: 10.1039/c5nr05218a.

We investigate the optoelectronic properties of the semiconducting (6,5) species of single-walled carbon nanotubes by measuring ultrafast transient transmission changes with 20 fs time resolution. We demonstrate that photons with energy below the lowest exciton resonance efficiently lead to...

Smallholder-dominated agricultural mosaic landscapes are highlighted as model production systems that deliver both economic and ecological goods in tropical agricultural landscapes, but trade-offs underlying current land-use dynamics are poorly known. Here, using the most comprehensive quantification of land-use change...

The association between hyperandrogenemia and the metabolic syndrome in morbidly obese women.

Diabetology & metabolic syndrome

Diabetol Metab Syndr. 2015 May 21;7:46. doi: 10.1186/s13098-015-0040-5. eCollection 2015.

BACKGROUND: Female abdominal obesity is associated with hyperandrogenemia (HA), but few studies have addressed the possible association between HA and metabolic syndrome (MetS) among obese women. Some studies indicate that insulin resistance may cause HA through different mechanisms. On...

Elevational patterns of Polylepis tree height (Rosaceae) in the high Andes of Peru: role of human impact and climatic conditions.

Frontiers in plant science

Kessler M, Toivonen JM, Sylvester SP, Kluge J, Hertel D.
PMID: 24847343
Front Plant Sci. 2014 May 09;5:194. doi: 10.3389/fpls.2014.00194. eCollection 2014.

We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near Cuzco (Peru) with respect to variations in human impact and climatic conditions, and compared air and soil temperatures between qualitatively defined dry and humid slopes....

High energetic excitons in carbon nanotubes directly probe charge-carriers.

Scientific reports

Soavi G, Scotognella F, Viola D, Hefner T, Hertel T, Cerullo G, Lanzani G.
PMID: 25959462
Sci Rep. 2015 May 11;5:9681. doi: 10.1038/srep09681.

Theory predicts peculiar features for excited-state dynamics in one dimension (1D) that are difficult to be observed experimentally. Single-walled carbon nanotubes (SWNTs) are an excellent approximation to 1D quantum confinement, due to their very high aspect ratio and low...

From above threshold ionization to statistical electron emission: the laser pulse-duration dependence of C60 photoelectron spectra.

Physical review letters

Campbell EE, Hansen K, Hoffmann K, Korn G, Tchaplyguine M, Wittmann M, Hertel IV.
PMID: 11017225
Phys Rev Lett. 2000 Mar 06;84(10):2128-31. doi: 10.1103/PhysRevLett.84.2128.

The photoelectron spectra of C60 ionized using a 790 nm laser with pulse durations varying from 25 fs to 5 ps have been determined. For 25 fs pulses, in the absence of fragmentation, the ionization mechanism is direct multiphoton...

The efficient synthesis of novel beta-diketonates equipped with functional carbazolyl moieties and their subsequent transformations in 5-hexyl-thienyl substituted carbazole derivatives is presented by utilizing an effective Stille cross-coupling reaction. The introduced beta-diketonates served as ancillary ligands for novel heteroleptic...
