Deutsche zahnarztliche Zeitschrift

Kerschbaum T.
PMID: 2700334
Dtsch Zahnarztl Z. 1989 Sep;44(9):647-52.

The development of modern information technology has brought about dramatic changes in the field of auxiliary instruments for scientific research, and by the same token, for research in dentistry. In the context of data acquisition literature data bases play...

Endobronchial Malposition of Matthys Pleural Catheter: A Case Report.

The Thoracic and cardiovascular surgeon reports

Kirschbaum A, Damanakis A, Rolfes C, Bartsch D.
PMID: 26693120
Thorac Cardiovasc Surg Rep. 2015 Dec;4(1):14-7. doi: 10.1055/s-0035-1564691. Epub 2015 Oct 07.

Background Matthys catheters (Matthys drainage A Set, Bösch Feinmechanik und Medizintechnik GmbH, Gottenheim, Germany) are thin catheters with an external diameter of 2.7 mm, which are often used in internal medicine to drain pleural effusions. After puncturing the pleural...

On the mechanism of Zn4O-acetate precursors ripening to ZnO: How dimerization is promoted by hydroxide incorporation.

The Journal of chemical physics

Milek T, Kirschbaum RW, V Gernler MS, Lübbert C, Segets D, Drewello T, Peukert W, Zahn D.
PMID: 26277139
J Chem Phys. 2015 Aug 14;143(6):064501. doi: 10.1063/1.4928190.

We report on a combined experimental and molecular modelling study on Zn4O ion clusters stabilized by acetate molecules (OAc). In particular, ab initio calculations of acetate substitution by hydroxide ions are compared with mass spectrometry data. Though quantum calculations...

Hydrocortisone Counteracts Adverse Stress Effects on Dual-Task Performance by Improving Visual Sensory Processes.

Journal of cognitive neuroscience

Weckesser LJ, Alexander NC, Kirschbaum C, Mennigen E, Miller R.
PMID: 27378327
J Cogn Neurosci. 2016 Nov;28(11):1784-1803. doi: 10.1162/jocn_a_01006. Epub 2016 Jul 05.

The impact of acute stress on executive processes is commonly attributed to glucocorticoid-induced disruptions of the pFC. However, the occipital cortex seems to express a higher density of glucocorticoid receptors. Consequently, acute stress effects on executive processes could as...

Synthesis, Properties, and Crystal Structures of Benzene-1,2-dithiolato Complexes of Thallium(I) and -(III).

Inorganic chemistry

Bosch BE, Eisenhawer M, Kersting B, Kirschbaum K, Krebs B, Giolando DM.
PMID: 11666810
Inorg Chem. 1996 Oct 23;35(22):6599-6605. doi: 10.1021/ic951411x.

The syntheses, molecular structures and properties of homoleptic 1,2-S(2)C(6)H(4) complexes of thallium(I) and thallium(III) with four-coordinated metal centers are described. Anaerobic treatment of TlCl, TlNO(3), or Tl(2)CO(3) with solutions of sodium methanolate and 1,2-(HS)(2)C(6)H(4) in methanol gave after metathesis...

Highly Stereoselective Synthesis of Perhydro-8a-(hydroxymethyl)phenanthrene-1,2,4,5,7,8-hexol and Derivatives.

The Journal of organic chemistry

[Elements making up the identity of the nurse in descriptions expressed by graduating students].

Revista gaucha de enfermagem

Silva EV, Kirschbaum DI.
PMID: 11993108
Rev Gaucha Enferm. 2001 Jan;22(1):83-100.

Identity is usually conceived by choosing a series of characteristics which should be truly considered a person's own; it searches to fulfill needs that other way would stop individuals to build their own destinies. We aimed to apprehend the...

Forest growth and species distribution in a changing climate.

Tree physiology

Kirschbaum MU.
PMID: 12651447
Tree Physiol. 2000 Mar;20(5):309-322. doi: 10.1093/treephys/20.5-6.309.

Climate change has many potential effects on plants, some detrimental to growth, others beneficial. Increasing CO(2) concentration can increase photosynthetic rates, with the greatest increases likely to be in C(3) plants growing in warm dry conditions. Increasing temperature directly...

Effects of water status and soil fertility on the C-isotope signature in Pinus radiata.

Tree physiology

Korol RL, Kirschbaum MU, Farquhar GD, Jeffreys M.
PMID: 12651529
Tree Physiol. 1999 Jul;19(9):551-562. doi: 10.1093/treephys/19.9.551.

The efficiency with which trees use water is a major determinant of growth under water-limited conditions. We investigated whether increased access to water and nutrients alters water-use efficiency in Pinus radiata D. Don. Intrinsic transpiration efficiency, defined here as...

Titanium and zirconium amido complexes ligated by 2,2'-Di(3-methylindolyl)methanes: synthesis, characterization, and ethylene polymerization activity.

Inorganic chemistry

Mason MR, Fneich BN, Kirschbaum K.
PMID: 14552606
Inorg Chem. 2003 Oct 20;42(21):6592-4. doi: 10.1021/ic0347236.

2,2'-Di(3-methylindolyl)methanes (L(2)H(2)) are introduced as dianionic, bidentate ligands of reduced pi-donating ability. Four complexes of the type L(2)Ti(NEt(2))(2) and L(2)Zr(NEt(2))(2)(THF) have been synthesized and characterized by elemental analysis, NMR ((1)H, (13)C) spectroscopy, and X-ray crystallography. Structural data confirm the...

Gas Exchange Analysis of the Fast Phase of Photosynthetic Induction in Alocasia macrorrhiza.

When leaves of Alocasia macrorrhiza that had been preconditioned in 10 micromoles photons per square meter per second for at least 2 hours were suddenly exposed to 500 micromoles photons per square meter per second, there was an almost...

Investigation of the CO(2) Dependence of Quantum Yield and Respiration in Eucalyptus pauciflora.

Plant physiology

Kirschbaum MU, Farquhar GD.
PMID: 16665319
Plant Physiol. 1987 Apr;83(4):1032-6. doi: 10.1104/pp.83.4.1032.

In leaves of C(3) plants, the rate of nonphotorespiratory respiration appears to be higher in darkness than in the light. This change from a high to a low rate of carbon loss with increasing photon flux density leads to...
