Impact of antioxidative treatment on nuclear factor kappa-B regulation during myocardial ischemia-reperfusion.

Interactive cardiovascular and thoracic surgery

Fischer UM, Antonyan A, Bloch W, Mehlhorn U.
PMID: 17670639
Interact Cardiovasc Thorac Surg. 2006 Oct;5(5):531-5. doi: 10.1510/icvts.2006.130765. Epub 2006 Jul 25.

Nuclear factor kappa-B (NFkappaB), a transcription factor, plays a role in numerous pathological states such as myocardial ischemia-reperfusion (I/R), apoptosis, and ischemic preconditioning. As both myocardial ischemia and reperfusion (by reactive oxygen intermediates) can activate NFkappaB, we investigated the...

PMID: 16665019
Plant Physiol. 1986 Sep;82(1):336-8. doi: 10.1104/pp.82.1.336.

Production of antioxidants was investigated in needles of fir (Abies alba Mill.) and spruce (Picea abies (L.) Karst) after exposure to low concentrations of SO(2), O(3), and a combination of both pollutants. Glutathione reacted most sensitively to pollutants followed...

Ionic Osmoregulation during Salt Adaptation of the Cyanobacterium Synechococcus 6311.

The mechanisms of salt adaptation were studied in the cyanobacterium Synechococcus 6311. Intracellular volumes and ion concentrations were measured before and after abrupt increases of external NaCl concentrations up to 0.6 molar NaCl. Equilibrium volumes, measured with a rapid...

Local investigation of femtosecond laser induced dynamics of water nanoclusters on Cu(111).

Physical review letters

Mehlhorn M, Carrasco J, Michaelides A, Morgenstern K.
PMID: 19659222
Phys Rev Lett. 2009 Jul 10;103(2):026101. doi: 10.1103/PhysRevLett.103.026101. Epub 2009 Jul 10.

We explore the dynamics of low temperature interfacial water nanoclusters on Cu(111) by femtosecond-laser excitation, scanning tunneling microscopy and density functional theory. Laser illumination is used to induce single molecules to diffuse within water clusters and across the surface,...

Incidence and outcome of gastrointestinal complications after cardiopulmonary bypass.

Interactive cardiovascular and thoracic surgery

Geissler HJ, Fischer UM, Grunert S, Kuhn-Régnier F, Hoelscher A, Schwinger RH, Mehlhorn U, Hekmat K.
PMID: 17670556
Interact Cardiovasc Thorac Surg. 2006 Jun;5(3):239-42. doi: 10.1510/icvts.2005.117382. Epub 2006 Feb 08.

Gastrointestinal complications (GI-complications) after CPB are rare, but are associated with high mortality and hospital cost. This retrospective analysis investigates the incidence, patient profile and post-operative course of GI-complications after CPB. The charts of 8869 adult patients, operated on...

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

Cuneo ME, Waisman EM, Lebedev SV, Chittenden JP, Stygar WA, Chandler GA, Vesey RA, Yu EP, Nash TJ, Bliss DE, Sarkisov GS, Wagoner TC, Bennett GR, Sinars DB, Porter JL, Simpson WW, Ruggles LE, Wenger DF, Garasi CJ, Oliver BV, Aragon RA, Fowler WE, Hettrick MC, Idzorek GC, Johnson D, Keller K, Lazier SE, McGurn JS, Mehlhorn TA, Moore T, Nielsen DS, Pyle J, Speas S, Struve KW, Torres JA.
PMID: 15903793
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Apr;71(4):046406. doi: 10.1103/PhysRevE.71.046406. Epub 2005 Apr 22.

We present observations for 20-MA wire-array z pinches of an extended wire ablation period of 57%+/-3% of the stagnation time of the array and non-thin-shell implosion trajectories. These experiments were performed with 20-mm-diam wire arrays used for the double-...

RNA-seq is being used increasingly for gene expression studies and it is revolutionizing the fields of genomics and transcriptomics. However, the field of RNA-seq analysis is still evolving. Therefore, we specifically designed this study to contain large numbers of...

Differences between thermal and laser-induced diffusion.

Physical review letters

Zaum Ch, Meyer-Auf-der-Heide KM, Mehlhorn M, McDonough S, Schneider WF, Morgenstern K.
PMID: 25910140
