Wissenschaft und Patriotismus. Der deutsch‐französische Krieg 1870/71
Authors: Vaupel Elisabeth 
Published: December 2007

AbstractIm Gegensatz zur Rolle der Chemie in den Weltkriegen wurde die Rolle der Chemie im deutsch‐französischen Krieg 1870/71 bisher noch wenig untersucht. In diesem nur 190 Tage dauernden Waffengang, der so viele Tote und Verletzte forderte wie kein anderer neuzeitlicher Krieg, wurden die Aktivitäten der Chemiker auf deutscher wie auf französischer Seite von den jeweiligen chemischen Gesellschaften beider Länder koordiniert. Auf deutscher Seite stand die Beschaffung von Desinfektionsmitteln, insbesondere Carbolsäure, im Vordergrund, während sich die französischen Chemiker bemühten, den Munitions‐ und Nahrungsmittelmangel im belagerten Paris zu beheben.
Factors associated with choosing a career in clinical psychology—undergraduate minority ethnic perspectives
Authors: Meredith Emmeline , Baker Martyn 
Published: December 2007

AbstractConcerns have been expressed by clinical psychologists about the preponderance of white members of the profession. While studies of minority ethnic recruitment into health professions and entry into higher education have been conducted at undergraduate level, the extent to which their results can be mapped on to issues of minority ethnic choosing of postgraduate training in clinical psychology is unknown. The aim of this study is to investigate the attraction or otherwise of professional clinical psychology to potential minority ethnic applicants. Q methodology was used to identify patterns of incentives and disincentives within a series of statements about the profession and its academic subject matter. Thirty‐seven UK minority ethnic undergraduate psychology students completed Q‐sort ratings. Along with narrative descriptions of seven factors derived from analysis of the data, we present three overall categories. Q‐sort data are by design defined by positive and negative aspects, and our interpretations indicate a mixture of overall attraction in all three categories. These patterns of thinking extend what was known from previous research, and explicate something of the complexity of participants' views of clinical psychology. Within the constraints of the study's limitations, we view them as a small contribution towards an empirically based understanding of factors influential in the recruitment of an ethnically more representative workforce. Copyright © 2007 John Wiley & Sons, Ltd.
Comparative flow immunophenotypic features of the inflammatory infiltrates of Hodgkin lymphoma and lymphoid hyperplasia
Authors: Hudnall S. David , Betancourt Eve , Barnhart Erin , Patel Jyoti 
Published: December 2007

AbstractBackground:Hodgkin lymphoma (HL) is characterized by relatively few malignant Reed‐Sternberg (RS) cells admixed within a reactive T cell rich inflammatory infiltrate. There is growing recognition that the HL‐associated inflammatory milieu may enhance rather than inhibit growth of RS tumor cells. Since little is known of the immunophenotype of the HL inflammatory infiltrate we have performed a detailed retrospective comparison of the flow immunophenotype of HL and reactive lymphoid hyperplasia (RLH) to identify HL‐specific immunophenotypic features.Methods:Single cell suspensions from 59 lymph nodes involved by HL (at initial diagnosis) and 38 lymph nodes involved by RLH were subjected to a battery of 3‐color combinations of well‐characterized fluorochrome‐conjugated monoclonal antibodies (DAKO) to a number of lymphocyte subsets. Cells were analyzed on a FACSCalibur flow cytometer with CellQuest software (Becton Dickinson).Results:Overall, CD4+ T cells are increased and CD19+ B cells decreased in HL vs. RLH, yielding median T:B cell (CD3:CD20) ratios of 2.3:1 and 1.6:1, resp. There is no difference in median CD8+ T cell % (16% in HL & RLH). The T:B cell ratio is highest in nodular sclerosis (NSHL) and lymphocyte depletion (LDHL) subtypes, and lowest in mixed cellularity HL (MCHL). There is no significant difference in CD4:CD8 ratio in any comparison. NKT cells were slightly increased in HL vs. RLH, especially in MCHL. CD4+CD25+ regulatory T cells are significantly increased in HL (9%) vs. RLH (2%), especially in MCHL (29%) and NSHL (12%). EBV positivity in NSHL is associated with older age, decreased CD4+CD25+ regulatory T cells, CD4:CD8 ratio, and CD19/CD20+ B cells, and increased NKT cells, and CD14+ low forward‐side scatter‐gated monocytes.Conclusion:The cellular composition of the reactive lymphocytic infiltrate in HL differs significantly from that seen in RLH, with significant differences also noted between HL subtypes. In general, the HL infiltrate contains increased T cells (CD4+ and NKT subsets), decreased B cells, and increased regulatory T cells in comparison with RLH. The major difference between HL subtypes is decreased CD4+ T cells in MCHL as compared with NSHL and NLPHL. The most notable EBV‐related difference in NSHL is increased regulatory T cells in EBV negative cases. While many differences in the reactive lymphocytic infiltrate of Hodgkin lymphoma and reactive lymphoid hyperplasia were identified, the sole difference that may prove to be of differential diagnostic value in flow cytometric analysis of HL versus RLH is the increased percentage of CD4+ bright CD25+ regulatory T cells in HL. © 2007 Clinical Cytometry Society
Scrape cytology of myositis ossificans: Report of a case and analysis of the cytologic findings described previously
Authors: Estrada‐Villaseñor E. , Cedillo E. Delgado , Martínez G. Rico 
Published: December 2007

AbstractMyositis ossificans is a reactive, ossifying process within soft tissues, which by its clinical and histological features is considered a pseudosarcomatous lesion. There are few reports that describe the cytologic findings in myositis ossificans, and each of these mentions different cellular composition. We describe the cytology of a case of myositis ossificans in a 14‐year‐old boy with clinical diagnosis of soft tissue sarcoma, and analyze the most common cytologic findings reported previously of this entity. We conclude that the different cellular composition reported, reflects the different histologic components of this lesion according to the area (zonation phenomenon), and that clinico‐radiologic correlation is essential for the cytological diagnosis.

Self‐Assembly of Luminescent Platinum‐Salen Schiff‐Base Complexes
Authors: Lü Xingqiang , Wong Wai‐Yeung , Wong Wai‐Kwok 
Published: December 2007

AbstractTreatment of K2PtCl4 with the MeO‐salen Schiff baseH2L [H2L = N,N′‐bis(3‐methoxysalicylidene)ethylene‐1,2‐diamine] gave the precursor complex PtL, which, upon recrystallization from two different solvent mixtures, afforded different solvate forms of PtL·H2O (1) and PtL·DMF (2) with different solid‐state colors. The self‐assembly of the PtL precursor with K2Pt(CN)4 or K2Pd(CN)4 leads to the isolation of isostructural compound [K2(PtL)2Pt(CN)4]·1.5H2O (3) or [K2(PtL)2Pd(CN)4]·1.5H2O (4), respectively. The solid‐state structures of 1–4 were established by X‐ray crystallography. It is interesting that the helix of the PtL units, along with the other two homochiral helical arrangements of K+ and M2+ (M = Pt or Pd) ions, can generate a unique “fake” example of a triple‐stranded helix in a 1‐D helical polymeric chain. Two such triple‐stranded helical chains intertwining one another can give rise to a double‐stranded helix formed by intermolecular weak C–H···N hydrogen‐bonding interactions with a long helical pitch of ca. 56 Å. The optical absorption and photoluminescence properties of 1–4 were also examined.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Synthesis, Crystal Structure and Thermal Reactivity of [ZnX2(2‐chloropyrazine)] (X = Cl, Br, I) Coordination Compounds
Authors: Bhosekar Gaurav , Jeß Inke , Lehnert Nicolai , Näther Christian 
Published: December 2007

AbstractReaction of zinc(II) halides with 2‐chloropyrazine in different solvents leads to the formation of five new coordination compounds that contain either only 2‐chloropyrazine or additional water molecules as donor ligands. In the ligand‐rich 1:2 compound catena[bis(2‐chloropyrazine‐N)]di‐μ‐chlorozinc(II) (1) the zinc atom is coordinated by two 2‐chloropyrazine ligands and four chlorine atoms in an octahedral fashion. The zinc atoms are connected by the chloride atoms forming linear chains. In the isotypic ligand‐rich 1:2 compounds bis(2‐chloropyrazine‐N)dibromozinc(II) (2) and bis(2‐chloropyrazine‐N)diiodozinc(II) (3) discrete complexes are found in which each zinc atom is coordinated by two 2‐chloropyrazine ligands and two halide atoms within distorted tetrahedra. The 1:1 compounds aqua‐(2‐chloropyrazine‐N)dibromozinc(II) (4) and aqua‐(2‐chloropyrazine‐N)diiodozinc(II) (5) are also isotypic and form discrete complexes in which the zinc atoms are surrounded by two halide atoms, one 2‐chloropyrazine ligand and one water molecule. Upon heating, compounds 1–5 form ligand‐deficient 1:1 and 2:1 compounds of composition [ZnX2(2‐chloropyrazine)] (X = halide) and [(ZnX2)2(2‐chloropyrazine)]. X‐ray powder diffraction shows that identical ligand‐deficient intermediates are obtained on decomposition of either [ZnX2L2] (L = 2‐chloropyrazine) or the [ZnX2L(H2O)] complexes. DFT calculations suggest that the formation of the [ZnX2L(H2O)] complex is energetically favoured for the heavier halide anions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Manganese‐Doped Zirconia Nanocrystals
Authors: Clavel Guylhaine , Willinger Marc‐Georg , Zitoun David , Pinna Nicola 
Published: December 2007

AbstractIn recent theoretical work, it was predicted that transition‐metal‐doped zirconia (ZrO2) can be ferromagnetic at room temperature with a dependence on the metal dopant and its oxidation state and concentration.1 For experimental verification of these predictions, manganese‐doped ZrO2 nanoparticles were synthesized. The synthesis was achieved by the benzyl alcohol route, which led to high‐quality nanocrystals with uniform size and shape. The obtained particles present a homogeneous distribution of the magnetic ion. The crystallographic phase was studied by XRD, electron diffraction, and high‐resolution TEM. The doping efficiency was determined at the macroscopic level by chemical analysis and at the nanoscale level by electron energy loss spectrometry. The local structure of the manganese ions in the ZrO2 matrix was characterized by electron paramagnetic resonance. Finally, the magnetic properties of the obtained nanocrystals were investigated by susceptibility measurements.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Quantification of carbonylated proteins in rat skeletal muscle mitochondria using capillary sieving electrophoresis with laser‐induced fluorescence detection
Authors: Feng Juan , Arriaga Edgar A. 
Published: December 2007

AbstractCarbonyl‐modified proteins are markers of oxidative damage. Here, we report a new method for detecting and quantifying carbonylated proteins by capillary sieving electrophoresis (CSE) with LIF detection (CSE‐LIF). Alexa 488 hydrazide is used for the specific labeling of carbonyls while 3‐(2‐furoyl) quinoline‐2‐carboxaldehyde (FQ) is used for protein labeling. BSA subjected to metal‐catalyzed oxidation is used to optimize the labeling reactions, confirm the separation power of CSE, and characterize the response of the LIF detector. The method is capable of detecting femtomole (fmol) amounts of carbonyls in proteins with molecular masses ranging from 26 to 30 kDa. Using this method, we determined that mitochondrial proteins isolated from skeletal muscle contains 2.1 ± 0.1 (average ± SD; n = 3) nmol carbonyl/mg protein. The methodology described here should be compatible with the analysis of single cells and needle biopsies taken from oxidative stress animal models.
Emotional awareness and core beliefs among women with eating disorders
Authors: Lawson Rachel , Emanuelli Francesca , Sines Jennie , Waller Glenn 
Published: December 2007

AbstractPatients with eating disorders have been shown to experience the emotional components of alexithymia—difficulties in identifying and describing emotions. In keeping with cognitive theories, which stress the role of schema‐level beliefs in understanding emotions, this study examined the core beliefs that are associated with this difficulty in women with eating disorders. Seventy eating‐disordered women completed standardised measures of core beliefs and alexithymia. There were no differences in alexithymia between diagnostic groups, so the women were treated as a single, transdiagnostic group. Multiple regression analyses showed specific patterns of association between the core beliefs and the emotional elements of alexithymia. Difficulties in identifying emotions were associated with entitlement beliefs, while difficulties in describing emotions were associated with both abandonment and emotional inhibition beliefs. These findings suggest that it may be necessary to work with core beliefs in order to reduce levels of alexithymia, prior to addressing the emotions that drive and maintain pathological eating behaviours.
