Mothers' dopamine receptor polymorphism modulates the relation between infant fussiness and sensitive parenting
Authors: Kaitz Marsha , Shalev Idan , Sapir Noam , Devor Noa , Samet Yekutiel , Mankuta David , Ebstein Richard P. 
Published: February 2010

AbstractWe determined whether the combination of the 48‐bp variable number tandem repeat polymorphism of the dopamine (DRD4) gene and infants' (fussy‐difficult) temperament predicted parenting sensitivity. The sample was comprised of 147 mothers and their 6‐month olds. Sensitive parenting was assessed by coding filmed interactions between mothers and infants. Infant temperament was assessed by parents' reports on a standard questionnaire. Moderated regressions models, with maternal education and infants' interactive behavior as controls, were used to test our hypotheses. Results showed no main effects of either temperament or DRD4, though the maternal DRD4 × infant temperament interaction was significant. Probes indicated that parents with a DRD4 7‐repeat allele behaved more sensitively to fussier infants and less sensitively to less fussy infants compared to parents without the 7‐repeat allele. Among those parents, sensitivity did not vary with infant temperament. This pattern of results indicates that mothers are differentially susceptible to infant fussiness, dependent on the presence of the 7‐repeat DRD4 allele. © 2010 Wiley Periodicals, Inc.

An Unusual N‐Bridged (Amido)(hydrido)(phenoxido)aluminium Dinuclear Compound – The Role of Nitrogen Substituents in Determining Nuclearity: A Combined Experimental and Theoretical Study
Authors: Martínez Gema , Chirinos Judith , Mosquera Marta E. G. , Cuenca Tomás , Gómez Enrique 
Published: February 2010

AbstractThe iminophenol 3,5‐tBu2‐2‐(OH)C6H2CH=NR and theaminophenol 3,5‐tBu2‐2‐(OH)C6H2CH2‐NHR (R = tBu, 2,6‐Me2C6H3, C6F5) were prepared in good yields by the appropriate synthetic methods. Reactions of these compounds with AlH3·NEtMe2 in toluene gave the mononuclear [AlH{3,5‐tBu2‐2‐(O)C6H2CH2‐NR}·NEtMe2] [R = 2,6‐Me2C6H3 (3), C6F5 (4)] or dinuclear [AlH{μ‐3,5‐tBu2‐2‐(O)C6H2CH2‐NtBu}]2 (5) phenoxido–amido aluminium derivatives. All synthesized complexes were characterized by NMR spectroscopic and analytical methods. The X‐ray structure of 5 shows a dinuclear molecule in which the aluminium centres are unusually linked by μ2‐N(amido) atoms to form a central planar Al2N2 ring in a clearly preferential disposition over the more common Al2O2 ring. The experimental work has been assisted by the B3LYP functional and the 6‐31G* basis sets as implemented in Gaussian 03 calculations to determine the role played by the nitrogen substituent group in the structural disposition adopted by the prepared (monohydrido)aluminium compounds, in order to evaluate the factors affecting the coordination modes of the phenoxido–amido ligand on aluminium.

Published: February 2010

AbstractInflammatory bowel diseases are represented by ulcerative colitis and Crohn's disease, both consisting of a chronic, uncontrolled inflammation of the intestinal mucosa of any part of the gastrointestinal tract with patchy or continuous inflammation. Ileo‐colonoscopy is considered the current gold standard imaging technique for the diagnosis. However, as the majority of patients need a long‐term follow‐up it would be ideal to rely on a non‐invasive technique with good compliance. This review focuses on nuclear medicine imaging techniques in Crohn's disease. Different scintigraphic methods of imaging cells involved in the pathogenesis are described. The radiopharmaceuticals can be divided into non‐specific radiopharmaceuticals for inflammation and specific radiopharmaceuticals that directly image lymphocytes involved in the process. This non‐invasive molecular imaging approach can be useful also because it images the small bowel or other areas––where colonoscopy is not useful—and that it may play a role for constant follow‐up, because relapses are frequent. Finally, an update on other imaging modalities, and particularly MRI, in the evaluation of Crohn's disease activity, is provided. Although MRI cannot directly detect inflammatory cells, it has shown a high sensitivity in detecting the macroscopic signs of inflammation at the level of the intestinal wall affected by Crohn's disease and Ulcerative colitis. The current diagnostic value of MRI in the detection of inflamed bowel segment and in the assessment of CD activity, as well the potentials MR spectroscopy, MR diffusion imaging and MR molecular imaging, is briefly discussed.

Differences in principals' leadership behavior in high‐ and low‐performing schools
Authors: Lindahl Ronald A. 
Published: February 2010

AbstractThis study was based on data from the 2008 Take20: Alabama Teaching and Learning Conditions Survey and focused on a comparison of teachers' perceptions of how school principals exercise their role in both high‐ and low‐performing elementary and middle schools that serve high‐poverty student populations. Teachers in the high‐performing schools consistently viewed their principals' behavior more positively than did their counterparts in the lower‐performing schools. Teachers reported less difference in regard to engaging the community to create shared responsibility for student and school success. Very little difference existed in the principal's involvement of teachers in key school decisions; neither population of principals scored high in this area.
Chemical imaging of glucose by CARS microscopy
Authors: Åkeson Madeleine , Brackmann Christian , Gustafsson Lena , Enejder Annika 
Published: February 2010

AbstractGlucose is one of the most fundamental molecules within life and bioengineering sciences. Present understanding of its role in cellular and bioengineering processes relies primarily on invasive, large‐scale biochemical analysis, providing no spatial information on glucose pools or fluxes. This work identifies an emerging microscopy technique based on coherent anti‐Stokes Raman scattering (CARS), which fulfills the need of quantitative imaging of glucose at the single‐cell level with submicrometer resolution. No sample preparation with reporter molecules is required, ensuring that the low‐weight metabolite is studied under natural conditions. The potential of CARS microscopy is illustrated by quantitatively mapping glucose fluxes and distributions in a microfluidic bioreactor and in lipid‐bilayer vesicles, the latter as a model for glucose transmembrane transport. Furthermore, the metabolic response to a glucose pulse was monitored in living yeast cells. This study signifies a new era within CARS microscopy for its use of monitoring carbohydrates, in particular glucose which is one of the most abundant molecules in nature.

Published: February 2010

AbstractA preparative high‐speed counter‐current chromatography method for isolation and purification of flavonoid compounds from Oroxylum indicum was successfully established by using ionic liquids as the modifier of the two‐phase solvent system. Two flavonoid compounds including baicalein‐7‐O‐diglucoside and baicalein‐7‐O‐glucoside were purified from the crude extract of O. indicum by using ethyl acetate–water–[C4mim][PF6] (5:5:0.2, v/v) as two‐phase solvent system. 36.4 mg of baicalein‐7‐O‐diglucoside and 60.5 mg of baicalein‐7‐O‐glucoside were obtained from 120 mg of the crude extract. Their purities were 98.7 and 99.1%, respectively, as determined by HPLC area normalization method. The chemical structures of the isolated compounds were identified by 1H‐NMR and 13C‐NMR.
Hydrogenation to products with IV below 1
Authors: Schaaf Tanja , Greven Heinzpeter 
Published: February 2010

AbstractThe hydrogenation of fatty acids (FA) or fatty acid methyl esters (FAME) is a fundamental process to manufacture basic oleochemicals, like stabilizers and surfactants. These kinds of oleochemicals are used in downstream processes, to obtain products which are easily bio‐degradable, non‐irritant to the skin, and equipped with other favourable characteristics. In principle the FA or FAME are hydrogenated in a reactor under pressure, higher temperature and in the presence of a metallic catalyst, such as nickel or palladium. The process can be controlled in a desired direction by appropriate choice of these parameters to get a product with different degrees of saturation, melting properties and colour. The commonly used process nowadays is a batch process. The hydrogenation reaction is carried out in a loop or stirred reactor, in the presence of a suspended catalyst. After the reaction the catalyst must be removed from the product by an elaborate and time‐consuming filtration. This leads to higher consumption of catalyst. Another concern is that Ni‐soaps can be formed during the process leading to deactivation of catalyst and the presence of nickel in the final product. Therefore the fixed bed method was developed to eliminate these disadvantages. A pilot plant was constructed in which the catalyst is fixed on a carrier matrix and filled into the reactor and a test run was carried out with FA from tallow and FAME from palm oil. The iodine value of < 0.1 in hydrogenated FAME was achieved as required by the industry for the production of surfactants. In the fixed bed hydrogenation for ME nickel catalyst and for FA a palladium catalyst is used. Furthermore catalyst is reused, its consumption is reduced and the formation of byproducts is minimized. The process is characterized by a high reliability, feed flexibility, easy control and high yield.
Myocardial infarction quantification with Manganese‐Enhanced MRI (MEMRI) in mice using a 3T clinical scanner

Published: February 2010

AbstractManganese (Mn2+) was recognized early as an efficient intracellular MR contrast agent to assess cardiomyocyte viability. It had previously been used for the assessment of myocardial infarction in various animal models from pig to mouse. However, whether Manganese‐Enhanced MRI (MEMRI) is also able to assess infarction in the acute phase of a coronary occlusion reperfusion model in mice has not yet been demonstrated. This model is of particular interest as it is closer to the situation encountered in the clinical setting. This study aimed to measure infarction volume taking TTC staining as a gold standard, as well as global and regional function before and after Mn2+ injection using a clinical 3T scanner. The first step of this study was to perform a dose‐response curve in order to optimize the injection protocol. Infarction volume measured with MEMRI was strongly correlated to TTC staining. Ejection fraction (EF) and percent wall thickening measurements allowed evaluation of global and regional function. While EF must be measured before Mn2+ injection to avoid bias introduced by the reduction of contrast in cine images, percent wall thickening can be measured either before or after Mn2+ injection and depicts accurately infarct related contraction deficit. This study is the first step for further longitudinal studies of cardiac disease in mice on a clinical 3T scanner, a widely available platform. Copyright © 2010 John Wiley & Sons, Ltd.
Chickpea‐mediated effects of Bacillus thuringiensis on Helicoverpa armigera and its larval parasitoid, Campoletis chlorideae
Authors: Dhillon M. K. , Sharma H. C. 
Published: February 2010

AbstractEfforts are underway to express toxin genes from Bacillus thuringiensis (Bt) in chickpea for controlling the pod borer, Helicoverpa armigera. The interaction between Bt toxins, Helicoverpa‐resistant chickpeas, and the parasitoid, Campoletis chlorideae are not fully understood. Therefore, we studied tritrophic interactions between Bt (administered as spray), chickpea genotypes, and the parasitoid, C. chlorideae. Chickpea genotypes resistant to H. armigera exercised a significant reduction in leaf feeding, survival and development of H. armigera, but did not influence the development and survival of the parasitoid, C. chlorideae. Bt sprays on different chickpea genotypes prolonged the larval period, and reduced pupation and adult emergence of C. chlorideae. Weights of H. armigera larvae showed a strong and positive association with C. chlorideae larval period on Bt treated, and a negative association on untreated chickpeas. The Bt‐intoxicated H. armigera larvae also resulted in reduced weight of the cocoons and adults of C. chlorideae, suggesting significant influence of host size on development and survival of the parasitoid. Bt toxins were detected in H. armigera larvae fed on Bt‐sprayed chickpeas, but not in C. chlorideae reared on H. armigera larvae fed on Bt‐treated chickpeas, and in the parasitoid adults fed on honey intoxicated with 0.05%Bt. The adverse effects of Bt on the parasitoid were largely through early mortality of H. armigera larvae or poor quality of the host. This information would be useful for planning appropriate strategies for testing and deployment of Bt‐transgenic chickpea with resistance to H. armigera for sustainable crop production.
REGIONAL AND FIRM COMPETITIVENESS IN THE SERVICE‐BASED ECONOMY: COMBINING ECONOMIC GEOGRAPHY AND INTERNATIONAL BUSINESS THEORY
Authors: STRÖM PATRIK , WAHLQVIST EVELINA 
Published: February 2010

ABSTRACTThis paper argues the case for combining international business theory and economic geography theory in order to understand the new rules of competition for both multinational corporations (MNCs) and regions in the globalising knowledge‐based economy. Sweden serves as a case study to illustrate the shifts of sectors and people skills that have paved the way for the transformation of the Swedish economy that has occurred over the last 15 years. Combining international business theory with that of economic geography produces the possibility of developing a conceptual framework for explaining the new dynamics and interaction that are occurring between people‐place‐firm. The enhanced importance of people and place, shifting pace, complex networks of production, and new balances of power together lead to changing practices and strategic implications for both MNCs and regions competing in the globalising knowledge‐based economy.
