Published: June 2007

AbstractDie Komplexe vom Typ CoX(D2H2)B (mit X z. B. = Halogen, D = Dimethylglyoxim‐Dianion und B = Base) setzen sich mit Grignard‐Verbindungen ähnlich wie Cyano‐oder Hydroxocorrinoide unter Bildung von coenzym B12‐artigen Kobaltorganylen der Zusammensetzung CoR(D2H2)B um. Bei der Reaktion mit Alkalimetallen bilden sich Salze vom Typ M⊕[Co(D2H2)B]⊖, die mit Alkyl‐ und Arylhalogeniden die Verbindungen des obengenannten Typs ergeben. Bei der Reduktion entstehen blau‐ bis blaugrüne, dem Vitamin B12s entsprechende Verbindungen (vermutlich komplexe Kobalthydride), die sich mit Diazomethan, Alkylhalogeniden, Alkenen und Alkinen unter Bildung von Kobaltorganyl‐dimethylglyoxim‐Komplexen umsetzen.

AbstractCyclopropane und Cyclobutane lassen sich in Gegenwart konzentrierter Schwefelsäure bei Temperaturen zwischen 20 und 70° mit Kohlenmonoxyd zu aliphatischen Carbonsäuren umsetzen. Die H. KOCHsche Carbonsäuresynthese läßt sich also auch auf reaktionsfähige Cycloaliphaten ausdehnen. Die Reaktionsfähigkeit der Cycloaliphaten nimmt mit zunehmender Alkylsubstitution ab. Cyclopropane reagieren leichter als die entsprechenden Cyclobutane.
Die Eigenschaften zweier dimerer Cyclooctatetraene vom Schmp. 53 und 76°
Authors: Schröder Gerhard 
Published: June 2007

AbstractDie von W. O. JONES vorgeschlagene Struktur II für ein dimeres Cyclooctatetraen vom Schmp. 76° ist falsch und muß durch IV ersetzt werden. Dieses dimere Cyclooctatetraen besitzt sehr ungewöhnliche Eigenschaften. Auf Grund seines Homotropilidensystems gehört es in die neue Gruppe der Moleküle mit schneller und reversibler Valenzisomerisierung. — Beim Erhitzen des Diels‐Alder‐Adduktes aus IV und Acetylendicarbonsäureester entsteht ein Kohlenwasserstoff VI, der ebenfalls einer schnellen und reversiblen Valenzisomerisierung unterliegt.

Published: June 2007

AbstractObjectivesTo assess differences in clinical characteristics, treatment and outcome between men and women with heart failure (HF) treated at a multidisciplinary HF unit. All patients had their first unit visit between August 2001 and April 2004.PatientsWe studied 350 patients, 256 men, with a mean age of 65 ± 10.6 years. In order to assess the pharmacological intervention more homogeneously, the analysis was made at one year of follow‐up.ResultsWomen were significantly older than men (69 ± 8.8 years vs. 63.6 ± 10.9 years, p < 0.001). Significant differences were found in the HF etiology and in co‐morbidities. A higher proportion of men were treated with ACEI (83% vs. 68%, p < 0.001) while more women received ARB (18% vs. 8%, p = 0.006), resulting in a similar percentage of patients receiving either of these two drugs (men 91% vs. women 87%). No significant differences were observed in the percentage of patients receiving beta‐blockers, loop diuretics, spironolactone, anticoagulants, amiodarone, nitrates or statins. More women received digoxin (39% vs. 22%, p = 0.001) and more men aspirin (41% vs. 31%, p = 0.004). Carvedilol doses were higher in men (29.4 ± 18.6 vs. 23.8 ± 16.4, p = 0.03), ACEI doses were similar between sexes, and furosemide doses were higher in women (66 mg ± 26.2 vs. 56 mg ± 26.2, p < 0.05). Mortality at 1 year after treatment analysis was similar between sexes (10.4% men vs. 10.5% women).ConclusionsDespite significant differences in age, etiology and co‐morbidities, differences in treatment between men and women treated at a multidisciplinary HF unit were small. Mortality at 1 year after treatment analysis was similar for both sexes. Copyright © 2007 Wiley Periodicals, Inc.
Amphiphilic Organic Ion Pairs in Solution: A Theoretical Study
Authors: Pradines Vincent , Poteau Romuald , Pimienta Veronique 
Published: June 2007

AbstractThe macroscopic manifestation of hydrophobic interactions for amphiphilic organic ion pairs (tetraalkylammonium–anion) has been shown experimentally by measuring their association constants and their affinity with the organic phase. Beyond a certain size, there is a direct relation between association constants and chain lengths in tetraalkylammonium ions. We propose to cast a bridge between these results and geometrical properties considered at the level of a single ion pair by means of quantum chemistry calculations performed on model systems: trimethylalkylammonium–pentyl sulfate instead of tetraalkylammonium–dodecyl sulfate. Two limiting cases are considered: head‐to‐head configurations, which yield an optimal electrostatic interaction between polar heads, and parallel configurations with a balance between electrostatic and hydrophobic interactions. All properties (geometries, complexation energies, and atomic charges) were obtained at the MP2 level of calculation, with water described by a continuum model (CPCM). Dispersion forces link hydrocarbon chains of tetraalkylammonium ions and pentyl sulfate, thus yielding (for the largest ion pairs) parallel configurations favored with respect to head‐to‐head geometries by solute–solvent electrostatic interactions. Given the small experimental association energies, we probe the accuracy limit of the MP2 and CPCM methods. However, clear trends are obtained as a function of chain length, which agree with the experimental observations. The calculated monotonic stabilization of ion pairs when the hydrocarbon chain increases in length is discussed in terms of electrostatic interactions (between ions and between ion pairs and water), dispersion forces, and cavitation energies.
Synthesis, Characterization, and Photophysical Properties of Some Heterodimetallic Bisporphyrins of Ytterbium and Transition Metals – Enhancement and Lifetime Extension of Yb3+ Emission by Transition‐Metal Porphyrin Sensitization

Published: June 2007

AbstractA series of d‐f heterodimetallic bisporphyrin complexes (YbZn, YbPd, and YbPt), in which a YbIII porphyrinate moiety is linked to a transition‐metal porphyrinate moiety by a flexible three‐carbon chain, were synthesized. They were fully characterized by high‐resolution mass spectrometry, 1H and 31P NMR spectroscopy, electronic absorption, andfluorescence methods. Variable‐temperature near‐infrared photoluminescence studies showed that the transition‐metal porphyrinate moiety would enhance the ytterbium(III) emission centered at about 998 nm and extend its emission lifetime. YbPd and YbPt showed large two‐photon absorption cross‐section values because of the interaction between the porphyrin units, which caused a loss of centrosymmetry. Optical limiting investigation demonstrated that [Yb(TPP)(LOMe)] and YbPt have comparable performance to C60 by virtue of their heavy‐metal effect. Our results indicate that these bisporphyrin dimetallic complexes will find valuable applications in the field of nonlinear optics. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
Champ or chump: strategic utilization of dual social identities of others
Authors: Stelzl Monika , Janes Leslie , Seligman Clive 
Published: June 2007

AbstractThe Jamaican‐born, Canadian sprinter, Ben Johnson, won the gold medal at the 1988 Olympics, but afterward was disqualified for steroid use. At the time Johnson's identity in the Canadian media appeared to shift—he was ‘Canadian’ after winning the gold medal but ‘Jamaican’ after disqualification. We tested this hypothesis via an archival study of a newspaper database of Canadian newspapers. The results confirmed the speculation. In the second study with Canadian research participants, the nationality of a fictional athlete was experimentally manipulated. He either possessed Canadian‐ American (shared) or Belgian‐American (non‐shared) identity. The athlete's performance outcome at an Olympic event was also manipulated. In the shared identity condition the athlete was perceived as more Canadian when he won than when he lost. There were no significant differences in nationality judgment when neither of the athlete's dual nationalities was Canadian. Results regarding perceptions of similarity paralleled the nationality‐ratings results. Findings from these two studies illustrate an interesting extension of BIRGing and CORFing strategies in which multiple social identities of others are used strategically to include or exclude others from the in‐group.

Multi‐impulsive bulimia: Description of an inpatient eclectic treatment programme and a pilot follow‐up study of its efficacy
Authors: Lacey J. Hubert , Read Timothy R. C. 
Published: June 2007

AbstractThis paper describes an inpatient treatment programme specifically designed for normal weight bulimia nervosa patients who have a co‐morbidity marked by alcohol and drug abuse, ‘cutting’, repeated overdosing or stealing, or sexual disinhibition (multiimpulsive bulimia). The programme uses a rigorous ward regime and simple behavioural counselling, under the direction of a nurse‐counsellor to bring control to the many addictive and self‐damaging behaviours. The underlying emotional and personality issues are addressed by focal‐interpretive (psychodynamic) and cognitive techniques in both group and individual sessions. Major use is made of creative therapies and reality‐orientated therapies. General psychodynamic groups are mixed with focal groups using cognitive techniques. Patients respond well and the improvement in symptomatology is maintained during follow‐up. Those patients who describe poor peer relationships in adolescence and who find engagement in psychotherapy difficult, do poorly.
Maternal recall of management of childhood eating in anorexic and bulimic women: Maintaining food fussiness
Authors: Machan Julie , Waller Glenn 
Published: June 2007

AbstractIn a preliminary study, mothers' recalled control of food fussiness in their children was examined, to establish whether its effect differed between eating‐disordered and non‐eating‐disordered women. Overall, maternal use of reward maintained the fussiness (rather than reducing it), in keeping with the findings of previous research. This recalled effect occurred at an earlier age for the eating‐disordered women. It is suggested that this temporal disparity may be linked to a general level of early overconcern on the part of mothers of children who will later present with eating disorders.
Why Do We Diagnose Different Types of Eating Disorder? Arguments for a Change in Research and Clinical Practice
Authors: Waller Glenn 
Published: June 2007

AbstractIt is argued that the diagnosis of different types of eating disorders lacks either scientific validity or clinical utility, and that the forthcoming elaboration of diagnostic schemes (DSM‐IV) is unlikely to improve matters. The central problem with the diagnosiscentred model of the eating disorders seems to be that it is based on an inappropriate model of clinical practice, focusing on syndromes rather than symptoms. However, it would be equally invalid to assume that there is little or no similarity across eatingdisorder sufferers, as suggested by an individual‐centred model. Our understanding of the psychopathology and treatment of the eating disorders would benefit from employing a more clinically‐appropriate model of practice—the ‘scientist practitioner’ model. Discarding specific diagnoses and using this model would help to make clinical practice and research in the eating disorders more mutually informative.
The experience and impact of pregnancy in bulimia nervosa: A series of case studies
Authors: Lewis Linda , le Grange Daniel 
Published: June 2007

AbstractThe aim of the present study was to investigate the impact of pregnancy on women suffering from bulimia nervosa. Six mothers completed several rating scales and participated in a semi‐structured interview. These were used to construct a case study of the subjects with regard to their emotional experiences during pregnancy and their eating pathology during and following the pregnancy. Fears commonly experienced during the course of pregnancy included losing control of their eating and weight, causing damage to the unborn child by engaging in bulimic practices and not being able to cope with a newborn infant. With regard to eating pathology during pregnancy, subjects did not experience an amelioration in bulimic symptoms. In the puerperium there was a resurgence of bulimic symptoms for all women either at a level of severity equal to or worse than before conception. Albeit tentative, pregnancy does not seem to provide women with an opportunity for recovery from bulimia nervosa and pregnancy may, in some cases, result in an exacerbation of bulimic symptoms.
Problems and possibilities of the prevention of eating disorders
Authors: Noordenbos Greta 
Published: June 2007

AbstractResearch to improve the possibilities of primary, secondary and tertiary prevention is desirable, because many young women in western societies develop eating disorders, which are difficult to treat. It usually takes a long time before people with an eating disorder improve or recover from it (Herzog et al. 1992b). Researchers have shown that the shorter the duration of the eating disorder, the better the prognosis for recovery (Morgan and Russell, 1975; Herzog et al. 1992a). Prevention, however, is not easy to realize. There are many problems to be solved. In this article, I will firstly present the most important problems of primary, secondary and tertiary prevention of anorexia and bulimia nervosa. In the second place, I will make some suggestions concerning prevention of eating disorders, and make a plea for an integrated model for primary, secondary and tertiary prevention.
The aetiology of eating disorders: A hypothesis of the interplay between social, cultural and biological factors
Authors: Raphael Frances J. , Lacey J. Hubert 
Published: June 2007

AbstractEating disorders, though recognized for centuries, are increasing in prevalence. The increase in rate is particularly remarkable over the last 30–40 years. The article considers how social function stems from biological function and evolution. It also shows how biological function may hamper social development to the detriment of individuals and that anorexia nervosa may stem from this. Social and cultural influences relevant to this change are examined, especially the conflicting roles which women find themselves balancing. Reference is made to the representation of women in the media. Reference is made also to the role of those external agencies which have historically controlled populations (both men and women), such as religious bodies and governments, but which to some extent have been rejected. Evidence from indepth studies of women with eating disorders and from transcultural studies are included to support the authors' ideas.
Multiple family weight pathology and outcome in anorexia nervosa: A longitudinal case study
Authors: Gowers Simon G. , Weaver Andrew 
Published: June 2007

AbstractA prospective family case study was conducted whilst one member, a 14‐year‐old girl, underwent individual outpatient treatment for anorexia nervosa. Despite her being a twin within a family with multiple weight and other pathologies, substantial recovery was achieved and continued at two‐year follow‐up. Evidence of decompensation in other family members was suggested by clinical interview data but not by concurrent self‐report measures of eating disorder or neurotic symptomatology.
Eating attitudes and behaviours in a swiss student sample: Some preliminary results
Authors: Buddeberg‐Fischer Barbara , Sieber Martin , Bernet Rita , Buddeberg Claus 
Published: June 2007

AbstractThis paper reports the results of a pilot study of eating attitudes and behaviours of 150 female and male students, 15‐20 years of age. Screening with the EAT‐26 revealed 6.4 per cent of the 78 girls scoring in the high‐risk range (⩾ 20 points). Of the females 14 per cent and 4.2 per cent of the males fell in the low‐risk range (10‐19 points). The additionally administered questionnaires showed significant differences between female and male adolescents but few differences between the risk and the non‐risk female group. Further steps in a larger epidemiological study are discussed to find out more details of the development of disturbed eating behaviours and their influence of turning to eating disorders.
