The Tautomeric Persistence of Electronically and Sterically Biased 2‐Quinolinones
Authors: Volle Jean‐Noël , Mävers Ursula , Schlosser Manfred 
Published: March 2008

AbstractOne dozen of tailormade model 3‐fluoro‐2(1H)‐quinolinones were synthesized in order to be investigated by UV‐, IR‐ and NMR spectroscopic techniques. All of these compounds were found to exist predominantly, if not exclusively, in the lactam (carboxamide, 1,2‐dihydro‐2‐oxoquinoline) form. No tautomeric lactim (iminol, azaphenol) structure was detected. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Least‐squares spectral element method applied to the Euler equations
Authors: Gerritsma Marc , van der Bas Rokus , De Maerschalck Bart , Koren Barry , Deconinck Herman 
Published: March 2008

AbstractThis paper describes the application of the least‐squares spectral element method to compressible flow problems. Special attention is paid to the imposition of the weak boundary conditions along curved walls and the influence of the time step on the position and resolution of shocks. The method is described and results are presented for a supersonic flow over a wedge and subsonic, transonic and supersonic flow problems over a bump. Copyright © 2008 John Wiley & Sons, Ltd.
Detection of a t(1;22)(q23;q12) translocation leading to an EWSR1‐PBX1 fusion gene in a myoepithelioma

Published: March 2008

AbstractChromosome banding as well as molecular cytogenetic methods are of great help in the diagnosis of mesenchymal tumors. Myoepithelial neoplasms of soft tissue including myoepitheliomas, mixed tumors, and parachordomas are diagnoses that have been increasingly recognized the last few years. It is still debated which neoplasms should be included in these morphologically heterogeneous entities, and the boundaries between them are not clear‐cut. The pathogenetic mechanisms behind myoepithelial tumors are unknown. Only five parachordomas and one mixed tumor have previously been karyotyped, and nothing is known about their molecular genetic characteristics. We present a mesenchymal tumor classified as a myoepithelioma that had a balanced translocation t(1;22)(q23;q12) as the sole karyotypic change. A novel EWSR1‐PBX1 fusion gene consisting of exons 1–8 of the 5′‐end of EWSR1 and exons 5–9 of the 3′‐end of PBX1 was shown to result from the translocation. Both genes are known to be targeted also by other neoplasia‐specific translocations, PBX1 in acute lymphoblastic leukemia and EWSR1 in several solid tumors, most of which are malignant. Based on the structure of the novel fusion gene detected, its transforming mechanism is thought to be the same as for other fusion genes involving EWSR1 or PBX1. © 2008 Wiley‐Liss, Inc.
Increase of MCP‐1 (CCL2) in myelin mutant Schwann cells is mediated by MEK‐ERK signaling pathway
Authors: Fischer Stefan , Weishaupt Andreas , Troppmair Jakob , Martini Rudolf 
Published: March 2008

AbstractMacrophages are critically involved in the pathogenesis of genetically caused demyelination, as it occurs in inherited demyelinating neuropathies. On the basis of the observation that upregulation of the Schwann cell‐derived chemokine MCP‐1 (CCL2) is a pathologically relevant mechanism for macrophage activation in mice heterozygously deficient for the myelin component P0 (P0+/−), we posed the question of the intracellular signaling cascade involved. By using western blot analysis of peripheral nerve lysates the MAP‐kinases extracellular signal‐regulated kinase 1/2 (ERK1/2) and MAP kinase/ERK kinase 1/2 (MEK1/2) showed an early and constantly increasing activation in P0 mutants. Furthermore, in nerve fibers from the P0+/− mutants, Schwann cell nuclei were much more often positive for phosphorylated ERK1/2 than in nerve fibers from wild type mice. In vitro experiments using the MEK1/2‐inhibitor CI‐1040 decreased ERK1/2‐phosphorylation and MCP‐1 expression in a Schwann cell‐derived cell line. Finally, systemic application of CI‐1040 lead to a decreased ERK1/2‐phosphorylation and substantially reduced MCP‐1‐production in peripheral nerves of P0+/− mutant mice. Our study identifies MEK1/2‐ERK1/2 signaling as an important intracellular pathway that connects the Schwann cell mutation with the activation of pathogenetically relevant macrophages in the peripheral nerves. These findings may have important implications for the treatment of inherited peripheral neuropathies in humans. © 2008 Wiley‐Liss, Inc.
Syntheses of isotope‐labeled tobacco‐specific nitrosamines and their metabolites
Authors: Desai Dhimant , Krzeminski Jacek , El‐Bayoumy Karam , Amin Shantu 
Published: March 2008

AbstractWe report here on the syntheses of three deuterium‐labeled tobacco‐specific nitrosamines namely [2,4,5,6‐d4]nitrosonornicotine([2,4,5,6‐d4]NNN), 4‐(methylnitrosamino)‐1‐(3‐[2,4,5,6‐d4]pyridyl)‐1‐butanone ([2,4,5,6‐d4]NNK), and 4‐(methylnitrosamino)‐1‐(3‐[2,4,5,6‐d4]pyridyl)‐1‐butanol ([2,4,5,6‐d4]NNAL). A metabolite of NNK and myosmine, 4‐hydroxy‐1‐(3‐[2,4,5,6‐d4]pyridyl)‐1‐butanone, was also synthesized. The synthetic strategy reported here is similar to that reported in the literature for the preparation of corresponding unlabeled compounds. The commercially available [2,4,5,6‐d4]ethylnicotinate was used as starting material. During the course of these syntheses [2,4,5,6‐d4]myosmine and [2,4,5,6‐d4]nornicotine were obtained as stable intermediates. These isotope‐labeled compounds are useful internal standards for quantification of TSNA and their metabolites in smokers in molecular epidemiological studies.

Physiological noise in MR images: An indicator of the tissue response to ischemia?

AbstractPurposeTo determine whether measuring signal intensity (SI) fluctuations in MRI time series data from acute stroke patients would identify ischemic tissue.Materials and MethodsPrebolus perfusion‐weighted MRI data from 32 acute ischemic stroke patients (N = 32) was analyzed as a time series. Ischemic and normal tissue regions were outlined and compared.ResultsThe magnitude of the measured SI fluctuations was significantly lower in ischemic regions relative to normal tissue. Spatial differences in these fluctuations occurred in a manner that was different than other perfusion‐based metrics.ConclusionPrior studies have shown that SI fluctuations in MRI time series data correspond to the presence of physiological “noise,” which includes vasomotion, an autoregulatory phenomenon that affects the tissue response to ischemia. In this study, SI fluctuations were found to decrease in ischemia, consistent with the notion that small vessels will remain open (fluctuations in vessel diameter will decrease) when there is a challenge to flow. Spatial variation in SI fluctuations appeared to be different from spatial variation seen on other perfusion‐based metrics, suggesting that a separate contrast mechanism is responsible, one that might be of diagnostic and prognostic value in acute stroke in which the ability of tissue to withstand ischemia is currently not well visualized.
