Structural Chemistry of a New 10H Hexagonal Perovskite: BaMn0.4Fe0.6O2.73
Authors: Miranda Laura , Ramírez‐Castellanos Julio , Hernando María , Varela Aurea , González‐Calbet José M. , Parras Marina 
Published: April 2007

AbstractA new 10H polytype has been stabilized in the BaMn1–xFexO3–y system with the composition BaMn0.4Fe0.6O2.73. The anionic composition has been established by a reduction and re‐oxidation cycle in the stability range of this phase. The structural characterization was carried out by high‐resolution electron microscopy (HREM), electron diffraction, and X‐ray diffraction. The structure is closely related to the ideal (hch′ch)2 10H polytype with two oxygen‐deficient hexagonal (h′) BaO2–y layers per unit formula. This framework gives rise to blocks of three octahedra sharing faces linked by corners to two corner‐sharing tetrahedra.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

Published: April 2007

AbstractThe parent compounds of phosphanylboranes of the type (LA)H2P–BH2(LB) (LA = Lewis acid, LB = Lewis base) stabilised by Lewis acid/Lewis base have been synthesised by using perfluorinated main‐group Lewis acids. The Lewis acid–phosphane adducts (C6F5)3BPH3, (C6F5)3BPPhH2 and (C6F5)3GaPPhH2 (3) were used as starting materials, which upon lithiation with nBuLi react with the chlorinated Lewis base borane adduct ClBH2NMe3. The LA/LB stabilisedphosphanylboranes (C6F5)3BPH2BH2NMe3 (1), (C6F5)3BPPhHBH2NMe3 (4) and (C6F5)3GaPPhHBH2NMe3 (5), were obtained via salt elimination reactions. (C6F5)3GaPH2BH2NMe3 (2) was not accessible using this method due to the unavailability of an efficient synthetic route to (C6F5)3GaPH3. The synthesis of 2 could be achieved quantitatively via reaction of PH2BH2NMe3 with (C6F5)3Ga·Et2O. All products were comprehensively characterised by spectroscopic methods and X‐ray crystallography. Additionally, the intermediate products (C6F5)3BPH2Li and (C6F5)3GaPPhH2 (3) were spectroscopically characterised.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

AbstractPentanuclear linear‐chain PtPd complexes {[Pt2(NH3)2X2(μ‐pivalamidato)2(CH2COCH3)]2[PdX′4]}·2CH3COCH3 (X = X′ = Cl (1a), X = Cl, X′ = Br (1b), X = Br, X′ = Cl (1c), X = X′ = Br (1d)) composed of a monomeric PdII complex sandwiched by two amidato‐bridged dimeric PtIII units were synthesized from the reaction between the acetonyl dinuclear PtIII complexes having equatorial halide ligands [Pt2(NH3)2X2(μ‐pivalamidato)2(CH2COCH3)]X″ (X = Cl (2a), Br (2b), X″ = NO3–, CH3C6H4SO3–) and K2[PdX′4] (X′ = Cl, Br). The X‐ray crystallographic analysis of 1a–1d shows that the complexes have metal–metal bonded linear Pt2PdPt2 structures. The pentanuclear PtPd complexes have either an arch backbone structure or a sigmoid backbone structure, depending on the solvent of crystallization. The UV/Vis/NIR spectra clearly show the existence of a rare charge‐transfer band from Pd to Pt in the pentanuclear PtPd complexes. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

AbstractThe initial use of 2‐pyridyl‐substituted oximes [(py)C(R)NOH; R = Me, Ph]/sulfate blend in nickel(II) chemistry has yielded a family of hexanuclear clusters. The syntheses, structures and magnetic properties are reported of [Ni6(SO4)4(OH){(py)C(Me)NO}3{(py)C(Me)NOH}3(MeOH)2(H2O)] (1),[Ni6(SO4)4(OH){(py)C(ph)NO}3{(py)C(ph)NOH}3(MeOH)3] (2)and [Ni6(SO4)4(OH){(py)C(ph)NO}3{(py)C(ph)NOH}3(H2O)3] (3), where (py)C(Me)NOH is methyl 2‐pyridyl ketone oxime and (py)C(ph)NOH is phenyl 2‐pyridyl ketone oxime. The hexanuclear molecules present in the three complexes have similar structures which contain the [Ni6(μ3‐OH)(μ3‐SO4)3(μ3‐ONR)3]2+core. The core consists of six NiIIions arranged as two parallel equilateral triangular subunits, one small (Ni···Ni ca. 3.3 Å) and the other larger (Ni···Ni ca. 6.0 Å). Characteristic IR bands are discussed in terms of the known structures of1–3. The magnetic properties of1and2have been studied by variable‐temperature dc magnetic susceptibility techniques which indicate antiferromagnetic interactions. A simple 2‐Jmodel was found to be adequate to describe the similar thermal variation of the molar magnetic susceptibilities of1and2.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

Published: April 2007

AbstractStarting with the ω‐hydroxy and ω‐amino acid derivatives 13 and 21, the two closely related geodiamolide analogs 32 and 35, respectively, were prepared. Compared to the natural cyclodepsipeptide geodiamolide (1), the macrocycles 32 and 35 have a smaller ring size (17‐ vs. 18‐membered). Conformational analysis by ROESY spectroscopy and molecular dynamics simulation revealed that the reduced ring size causes the polypropionate sector to flip with regard to the geodiamolide conformation.(© Wiley‐VCH Verlag GmbH & Co.

Cover Picture: Photoacylation of Alcohols in Neutral Medium (Eur. J. Org. Chem. 13/2007)
Authors: Débieux Jean‐Luc , Cosandey Anne , Helgen Céline , Bochet Christian G. 
Published: April 2007

AbstractThe cover picture shows the photochemically promoted acylation of alcohols under very mild conditions. The experimental protocol is extremely simple, thanks to the use of a benchtop photochemical reactor based on UV LEDs. The acyl transfer proceeds well for primary, secondary and even tertiary alcohols. The choice of a long wavelength (up to 420 nm) allows the presence of otherwise photosensitive groups, which can later be photolyzed at a higher energy. Details are discussed in the article by C. G. Bochet et al. on p. 2073 ff.
Impact of time‐scale of the calibration objective function on the performance of watershed models
Authors: Sudheer K. P. , Chaubey I. , Garg V. , Migliaccio Kati W. 
Published: April 2007

AbstractMany of the continuous watershed models perform all their computations on a daily time step, yet they are often calibrated at an annual or monthly time‐scale that may not guarantee good simulation performance on a daily time step. The major objective of this paper is to evaluate the impact of the calibration time‐scale on model predictive ability. This study considered the Soil and Water Assessment Tool for the analyses, and it has been calibrated at two time‐scales, viz. monthly and daily for the War Eagle Creek watershed in the USA. The results demonstrate that the model's performance at the smaller time‐scale (such as daily) cannot be ensured by calibrating them at a larger time‐scale (such as monthly). It is observed that, even though the calibrated model possesses satisfactory ‘goodness of fit’ statistics, the simulation residuals failed to confirm the assumption of their homoscedasticity and independence. The results imply that evaluation of models should be conducted considering their behavior in various aspects of simulation, such as predictive uncertainty, hydrograph characteristics, ability to preserve statistical properties of the historic flow series, etc. The study enlightens the scope for improving/developing effective autocalibration procedures at the daily time step for watershed models.

Unaltered hepatic oxidative phosphorylation and mitochondrial permeability transition in wistar rats treated with nimesulide: Relevance for nimesulide toxicity characterization
Authors: Moreno António J. , Oliveira Paulo J. , Nova Carlos D. , Álvaro Ana R. , Moreira Renata A. , Santos Sandra M. D. , Macedo Tice 
Published: April 2007

AbstractNonsteroidal anti‐inflammatory drugs have been associated with hepatotoxicity in susceptible patients. One such example is nimesulide, a preferential cyclooxygenase 2–inhibitor, widely used for the treatment of inflammation and pain. It was suggested that nimesulide could exert its hepatotoxicity by altering hepatic mitochondrial function, which was demonstrated in vitro. The objective of this study was to verify whether liver mitochondria isolated from rats treated with doses of nimesulide well above therapeutic levels possessed decreased calcium tolerance and oxidative phosphorylation, which indicates in vivo nimesulide mitochondrial toxicity. Male and female rats received nimesulide or its vehicle twice daily, for 5 days, and were killed on the seventh day for the isolation of liver mitochondria. Mitochondrial respiration, transmembrane electric potential, and calcium tolerance were characterized in all experimental groups. Nimesulide had no effect on liver mitochondrial function. Indexes of mitochondrial integrity, calcium loading capacity, and oxidative phosphorylation efficiency were unchanged between liver mitochondria from treated and control animals. In the animals tested, no evidence of degraded mitochondrial function due to nimesulide administration could be found. The results corroborate the notion that despite recognized in vitro mitochondrial toxicity, nimesulide does not cause detectable mitochondrial dysfunction in Wistar rats, even when administered in much higher concentrations than those known to have anti‐inflammatory effects. © 2007 Wiley Periodicals, Inc.

AND‐34/BCAR3 differs from other NSP homologs in induction of anti‐estrogen resistance, cyclin D1 promoter activation and altered breast cancer cell morphology
Authors: Near Richard I. , Zhang Yujun , Makkinje Anthony , Borre Pierre Vanden , Lerner Adam 
Published: April 2007

AbstractOver‐expression of AND‐34/BCAR3/NSP2 (BCAR3) or its binding‐partner p130Cas/BCAR1 generates anti‐estrogen resistance in human breast cancer lines. Here, we have compared BCAR3 to two related homologs, NSP1 and NSP3/CHAT/SHEP, with regards to expression, anti‐estrogen resistance, and signaling. BCAR3 is expressed at higher levels in ERα‐negative, mesenchymal, than in ERα‐positive, epithelial, breast cancer cell lines. Characterization of “intermediate” epithelial‐like cell lines with variable ER‐α expression reveals that BCAR3 expression correlates with both mesenchymal and ERα‐negative phenotypes. Levels of the BCAR3/p130Cas complex correlate more strongly with the ERα‐negative, mesenchymal phenotype than levels of either protein alone. NSP1 and NSP3 are expressed at lower levels than BCAR3 and without correlation to ERα/mesenchymal status. Among NSP‐transfectants, only BCAR3 transfectants induce anti‐estrogen resistance and augment transcription of cyclin D1 promoter constructs. Over‐expression of all homologs results in activation of Rac, Cdc42 and Akt, suggesting that these signals are insufficient to induce anti‐estrogen resistance. BCAR3 but not NSP1 nor NSP3 transfectants show altered morphology, transitioning from polygonal cell groups to rounded, single cells with numerous blebs. Whereas stable over‐expression of BCAR3 in MCF‐7 cells does not lead to classic epithelial‐to‐mesenchymal transition, it does result in down‐regulation of cadherin‐mediated adhesion and augmentation of fibronectin expression. These studies suggest that BCAR's ability to induce anti‐estrogen resistance is greater than that of other NSP homologs and may result from altered interaction of breast cancer cells with each other and the extracellular matrix.

Published: April 2007

AbstractPurpose.To retrospectively investigate the relationships between carotid flow velocities, clinical features and cardiac hemodynamics to assess the meaning and significance of reduced carotid flow velocities in patients with cerebral ischemic symptoms.Methods.We selected the files from patients who had undergone duplex Doppler sonographic examination of extracranial carotid arteries, echocardiography, and MR angiography, and in whom the following parameters were available: peak systolic (PSV) and end diastolic (EDV) flow velocity, pulsatility index (PI), and diameter of the left and right common (CCA) and internal (ICA) carotid arteries, intima–media thickness (IMT) of the left and right CCA, left ventricle (LV) mass, peak flow velocity on LV outflow tract, and fractional shortening (FS). Patients with stenosis of the carotid artery or its main intracranial branches were excluded, as were patients with major cerebral infarction, severe intracranial abnormality, or heart function disorder. The remaining 59 patients were subdivided according to the presence or absence of cerebral ischemic symptoms, diabetes mellitus, arterial hypertension, and hyperlipidemia for multivariate analyses and stepwise regressions.Results.Women had smaller diameters and lower PI in the left and right CCA, and smaller LV mass than men. Age, CCA diameter, and IMT showed an inverse correlation with carotid flow velocities in several arterial segments. There was a positive correlation between PSV in the left CCA and ICA and FS, and between PSV in the left CCA and peak velocity on LV outflow tract. Flow velocities in the left and right ICA were significantly slower in patients with than in patients without cerebral ischemic symptoms.Conclusions.Cardiac hemodynamics and carotid flow velocities are significantly related, only on the left side, probably due to larger hemodynamic stress. Increased intracerebral circulatory resistance is probably involved in the decrease in carotid flow velocity and increase in PI in patients with cerebral ischemic symptoms. © 2007 Wiley Periodicals, Inc.

Ultrasound biomicroscopy for estimation of tumor thickness for conjunctival melanoma
Authors: Ho Viet H. , Prager Thomas C. , Diwan Hafeez , Prieto Victor , Esmaeli Bita 
Published: April 2007

AbstractWe assessed the feasibility of using high‐frequency ultrasound biomicroscopy (UBM) in estimating thickness of conjunctival melanomas preoperatively. Three patients underwent UBM prior to excision of conjunctival melanoma between February 2003 and March 2006. Conjunctival tumor thickness was estimated via UBM in each case and compared with the estimated histopathologic tumor thickness (Breslow thickness). Patient 1 had an estimated thickness of 1.99 mm via UBM versus a Breslow thickness measurement of 1.5 mm based on the surgical specimen. Patient 2 had a UBM thickness measurement of 2.4 mm and a Breslow thickness of 2.23 mm based on the surgical specimen. In patient 3, both UBM thickness and Breslow thickness were 2.3 mm. The use of high‐frequency UBM is feasible for the estimation of tumor thickness for conjunctival melanomas. UBM may serve as an additional diagnostic tool for estimating tumor thickness before surgical resection of conjunctival melanoma. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2007
A differential paradox: The controversy surrounding the Scottish mental surveys of intelligence and family size
Authors: Ramsden Edmund 
Published: April 2007

AbstractIn 1947, the Scottish Council for Research in Education and the Population Investigation Committee conducted a survey of Scottish schoolchildren, exploring the relations between tested intelligence and fertility. The survey was not only significant for its size, measuring the IQ of all 11‐year‐olds at school on the day of testing, some 80,805 children, but also because it was a repeat survey. Its purpose was to establish whether the intelligence of the population had declined because of the negative correlation between IQ and family size. The paper will explore how the impetus for the 1947 survey came from attempts to revive the fortunes of the eugenics movement, based upon the interdisciplinary study of population. While most expected the study to provide evidence of a decline in intelligence, it revealed an increase. This was in spite of a continuing process of differential fertility. This paper will explore the influence of these results, described as a “paradox,” upon the future development of the eugenics movement and the sciences of population. While for many, the results were seen to have completely, and thankfully, undermined eugenic fears of degeneration, the supposed “resolution” of the paradox in 1962 provided the basis of a meritocratic and optimistic “new eugenics” that sought to reunite social and biological scientists concerned with human betterment in Britain and the United States. © 2007 Wiley Periodicals, Inc.
Local institutionalization, discontinuity, and German textbooks of psychology, 1816–1854
Authors: Teo Thomas 
Published: April 2007

AbstractIn the context of social and intellectual developments and the changing role of German universities in the first half of the nineteenth century, which led to the local institutionalization of the discipline of psychology at German universities, the structure and content of textbooks of psychology are discussed. Textbooks in the first half of the nineteenth century had a pedagogical function in training teachers, in socializing students into the field, and in providing students and readers with knowledge about the subject matter, methodology, and topics of psychology. The textbooks, representative of influence, philosophical‐psychological orientations, and different decades in the first half of the nineteenth century, are reconstructed with regard to the definition of psychology, the ways of studying the soul, and how to conceptually organize the field. The textbooks by Herbart, Beneke, and Waitz, which were written within a natural‐scientific programmatic vision for psychology, are contrasted with the traditional philosophically intended textbooks of Reinhold, Mußmann, George, and Schilling. Fischhaber's textbook forGymnasienis summarized. Issues regarding the continuity of psychology are discussed, and discontinuous developments in the history of German psychology are identified. © 2007 Wiley Periodicals, Inc.
