Mit ArgusLab Chromophore betrachten
Authors: Peichert Rasmus 
Published: July 2009

AbstractKann man sich eine Abiturprüfung oder eine Lehramtsprüfung im Fach Chemie vorstellen, bei der das Thema Farbstoffe nicht mehr vorkommen darf, weil es aus dem SII‐Kanon gestrichen wurde? Wohl kaum, hieße das doch, unseren Schülern hätte man eine der ergiebigsten Quellen für den Erwerb anwendbaren Wissens, für neue, interessante Erkenntnisse und schließlich auch für Freude an unserem Fach verschlossen.Den Vorwurf, das Thema Farbstoffe sei schwierig und würde oft zu theorielastig behandelt, sollte man ernst nehmen und sich um eine weitestgehende Vereinfachung bemühen. Dennoch steht fest: Um ein Minimum von Fachbegriffen kommt man nicht herum. Darüber allerdings, welche das sein sollten, gehen die Lehrmeinungen noch immer auseinander und die Diskussion verschiedener historisch gewachsener Konzepte hält an. Neuerdings lässt sich nun eine Entscheidung pro und kontra durch ein jedermann zugängliches Medium untermauern, das „molecular modeling”︁. Wie es mit dem Programm ArgusLab möglich ist, die Lichtabsorption eines konjugierten Systems zu erläutern, ohne auf MO‐theoretische oder mathematische Hintergründe näher einzugehen, will der folgende Beitrag zeigen.
Das an Schülervorstellungen orientierte Unterrichtsverfahren: Beispiel Neutralisation
Authors: Dörfler Tobias , Barke Hans‐Dieter 
Published: July 2009

AbstractPetermann, Friedrich und Oetken stellten vor kurzem „Das an Schülervorstellungen orientierte Unterrichtsverfahren”︁ vor ([1], für frühere Aufsätze siehe auch [19, 20]]. Gemeinsam mit dem Arbeitskreis der PH Freiburg arbeitet der Arbeitskreis Barke der Universität Münster im „Kooperationsteam Schülervorstellungen”︁. Erklärte Aufgabe ist die konkrete Einbindung von empirisch erhobenen Schülervorstellungen in den naturwissenschaftlichen Unterricht. Die Freiburger widmen sich vermehrt den Präkonzepten, also jenen vorläufigen Vorstellungen, die Lernende in der Lebenswelt entwickeln und in den Unterricht mitbringen. Neben solchen Präkonzepten unterscheidet man in der fachdidaktischen Forschung „hausgemachte Fehlvorstellungen”︁, die nicht in den Unterricht mitgebracht werden, sondern erst dort entstehen [2]. So bringen Schüler im Allgemeinen nur oberflächliche Vorkenntnisse zur Thematik Säuren und Laugen mit in den Unterricht: den Lehrpersonen muss es deshalb vor allem um die Prävention hausgemachter Fehlvorstellungen zu dieser Problematik gehen. Dazu gehört eine reflektierte Unterrichtsplanung und Durchführung, die bei Kenntnis der bekannten Fehlvorstellungen eben diese Vorstellungen im Chemieunterricht erst gar nicht entstehen lassen. Diesbezüglich wurde eine Unterrichtssequenz zum Thema „Neutralisation”︁ entwickelt und evaluiert. Die Evaluation ergibt, dass Schüler den eingesetzten Fragebogen nach jedem Unterrichtsabschnitt erfolgreicher beantworten, insbesondere korrigieren sie erfolgreich die mitgeteilten, möglichen Fehlvorstellungen durch ihre im Unterricht neu erworbene wissenschaftliche Vorstellung.

Published: July 2009

AbstractBACKGROUND:It was investigated whether the European Group for Blood and Marrow Transplantation risk score, previously established for chronic myeloid leukemia, could be used to predict outcome after allogeneic hematopoietic stem cell transplantation (HSCT) for hematological disease in general.METHODS:Age of patient, disease stage, time interval from diagnosis to transplant, donor type, and donor‐recipient sex combination were used to establish a score from 0 to 7 points. Its validity was tested in 56,505 patients, 33,113 (58%) male, 23,392 female, median age 33 years (range, 0.5‐77 years), with an allogeneic HSCT for a hematological disorder between 1980 and 2005.RESULTS:Survival probability at 5 years decreased from 71% (95% confidence interval [CI], 69%‐73%) for risk score 0 for the whole cohort (75%, 95% CI, 72%‐78% for the most recent time cohort) to 24% (95% CI, 21%‐27% for risk score 6 and 7; 25%, 95% CI, 22%‐29% most recent cohort). Transplant‐related mortality increased from 15% (95% CI, 14%‐17%) for risk score 0 (11%, 95% CI, 9%‐13%, most recent cohort) to 47% with risk score 6 and 7 (95% CI, 44%‐50%) for the whole cohort (45%, 95% CI, 42%‐48%, most recent cohort). The risk score was predictive in all disease categories, over all time periods, and was not altered by transplant techniques.CONCLUSIONS:Five well‐defined pretransplant patient and donor characteristics give a reasonable risk estimate of allogeneic HSCT. This risk score can provide a basis for the decision between transplant and nontransplant strategies. Cancer 2009. © 2009 American Cancer Society.
Adenosine diphosphate‐ribosylation factor 6 is required for epidermal growth factor‐induced glioblastoma cell proliferation
Authors: Li Ming , Wang Jide , Ng Samuel S. M. , Chan Chu‐yan , He Ming‐liang , Yu Fang , Lai Lihui , Shi Chao , Chen Yangchao , Yew David T. , Kung Hsiang‐fu , Lin Marie Chia‐mi 
Published: July 2009

AbstractBACKGROUND:Epidermal growth factor (EGF) signaling plays a pivotal role in gliomagenesis. The authors previously demonstrated that adenosine diphospate‐ribosylation factor 6 (ARF6), a member of the Ras‐related small guanosine‐5′‐triphospate‐binding protein family, is required for EFA6A‐induced glioma cell migration and invasion. However, the role of ARF6 in EGF signaling is unknown.METHODS:The authors analyzed messenger RNA (mRNA) levels of ARF6 and EGF receptor (EGFR) in 16 high‐grade glioma samples and in 6 low‐grade glioma samples by reverse transcriptase‐polymerase chain reaction analysis. To determine whether EGF induces ARF6 expression in human glioblastoma U87 cells through transcriptional regulation and EGFR activation, the levels of ARF6 were assayed in EGF‐treated U87 cells that were preincubated with a transcriptional inhibitor (actinomycin D) and an EGFR tyrosine kinase inhibitor (PD153035), respectively. The downstream signaling of EGFR‐mediated ARF6 up‐regulation also was investigated using specific inhibitors of mitogen‐activated protein kinase (MEK), phosphatidylinositol 3′ kinase (PI3K), and Janus kinase 2. The involvement of SP1 in the downstream signaling was studied by using an SP1 inhibitor (mithramycin A). Small‐interfering RNAs (siRNAs) targeting ARF6 were used to investigate the effects of ARF6 on EGF‐mediated glioma cell proliferation.RESULTS:The results demonstrated that ARF6 and EGFR mRNA levels were elevated in glioma tissues. Furthermore, EGF stimulated ARF6 expression in U87 cells in a dose‐dependent and time‐dependant manner. This stimulation was caused by increased transcription of ARF6 and by activation of the MEK/extracellular signal‐regulated kinase 1 and 2 (ERK1/2) and PI3K signaling pathways. It is noteworthy that SP1 was essential for EGF‐induced ARF6 up‐regulation. Finally, EGF‐induced glioblastoma cell proliferation depended on ARF6, because the suppression of ARF6 by siRNA or by a dominant‐negative mutant significantly inhibited EGF‐induced cell proliferation.CONCLUSIONS:The results of the current study suggested that EGF‐induced ARF6 expression plays a significant role in glioma cell proliferation.

Emotion‐focused therapy in a case of anorexia nervosa
Authors: Dolhanty Joanne , Greenberg Leslie S. 
Published: July 2009

AbstractAn emotion‐focused approach to the treatment of eating disorders and to case formulation is described in an individual with anorexia nervosa (AN). The basic theory of emotion‐focused therapy (EFT), the steps of case formulation and an outline of the tasks and course of treatment of an individual recently hospitalized on an inpatient unit for eating disorders highlight key aspects of the approach. The transformation in this individual, in terms of gaining access to her internal experience, understanding and tolerating her emotions, and working through her core themes of insecure attachment and worthlessness, is described. Weight and scores on self‐report measures at the outset of treatment and at 18 months are provided. Copyright © 2009 John Wiley & Sons, Ltd.Key Practitioner Message:

Guidelines for treating eating disorders are tenuous and new approaches showing promise must be developed.

Emotion‐focused therapy (EFT) shows promise in the treatment of eating disorders.

Description of the case shows the application of EFT to anorexia nervosa and illustrates the change in the individual in terms of recognizing and coping with emotional experience.
An exploration of the main sources of shame in an eating‐disordered population
Authors: Keith Laura , Gillanders David , Simpson Susan 
Published: July 2009

AbstractObjectives: Shame has received increased attention over recent years and has been shown to be a feature of many forms of psychopathology, including eating disorders. The current study contributes to this field by exploring relationships between shame and a variety of factors hypothesized to contribute to shame in a sample of 52 females with eating disorders.Design: A cross‐sectional questionnaire design was used.Methods: Participants were 52 women with eating disorders. They completed six questionnaires: The Experience of Shame Scale, the Parental Bonding Inventory, the Social Isolation Subscale of the Young Schema Questionnaire, the Eating Disorder Diagnostic Scale and the Hospital Anxiety & Depression Scale.Results: High levels of shame were observed, and not only shame around eating. A multiple regression analysis, with shame as the dependent variable and other variables as predictor variables revealed that the Social Isolation schema explained a substantial amount of total shame scores. Negative experiences of maternal care and eating disorder pathology also contributed a small but significant amount to the variance in shame scores.Conclusions: People with eating disorders experience generalized shame in relation to many aspects of their self and behaviour, not just shame around eating. Implications for future research, including the importance of prospective longitudinal designs, are discussed. Copyright © 2009 John Wiley & Sons, Ltd.

Published: July 2009

AbstractUnprecedented bifunctional enamine–metal Lewis acid catalysts have been developed. In this bifunctional catalytic system, a tridentate ligand tethered with a chiral secondary amine was designed to solve the acid–base self‐quenching problem leading to catalyst inactivation. This new bifunctional enamine–metal Lewis acid catalyst was found to catalyze aldol reactions of ketones efficiently in high yields and good to excellent diastereoselectivities and enantioselectivities.(© Wiley‐VCH Verlag GmbH & Co.

Differential mutagenicity of aflatoxin B1 in the liver of neonatal and adult mice
Authors: Chen Tao , Heflich Robert H. , Moore Martha M. , Mei Nan 
Published: July 2009

AbstractChildren are generally more sensitive to toxicants than adults, including an increased sensitivity to genotoxic carcinogens. We previously demonstrated that neonatal mice are also more sensitive to the mutagenic effects of the direct alkylating agents N‐ethyl‐N‐nitrosoamine and the arylamine 4‐aminobiphenyl than adult mice. In this study, we have evaluated the effect of age on the mutagenicity of the fungal toxin and liver carcinogen aflatoxin B1 (AFB1). Neonatal Big Blue transgenic mice were treated with 6 mg/kg AFB1, a treatment that produces liver tumors, while adult mice were treated with 6 and 60 mg/kg AFB1, treatments that do not result in tumors. The cII liver mutant frequency (MF) in mice treated with AFB1 as neonates was 22‐fold higher than in control neonatal mice, whereas the treatment of adult mice with either dose of AFB1 did not significantly increase the liver MF over the controls. In AFB1‐treated neonatal mice, the frequency of G:C → T:A transversion, a major type of mutation induced by AFB1, was about 82‐fold higher than for the control and 31‐fold higher than for adult mice treated with 60 mg/kg AFB1. Our mutagenicity findings parallel the relative carcinogenicity of AFB1 in neonatal and adult mice, and are consistent with previous observations of the lower level of hepatic glutathione S‐transferase and higher level of hepatic AFB1‐DNA adduction in neonatal mice compared to adult mice.
