Integrative Mapping of Gossypium hirsutum L. by Meiotic Fluorescent in Situ Hybridization of a Tandemly Repetitive Sequence (B77)
Authors: Ji Yuanfu , Zhao Xinping , Paterson Andrew H , Price H James , Stelly David M 
Published: April 2007

Abstract
We determined the relative positions of the tandem-repeat molecular cytogenetic marker B77, translocation breakpoints, and telosome arms in Gossypium hirsutum cytogenetic stocks by fluorescence in situ hybridization (FISH) analysis of meiotic quadrivalents in 16 single and 2 double translocation heterozygotes and five monotelodisomics. Results delimited the B77 FISH locus to the right arm of the D-subgenome chromosome 14 (14R) and the short arm (14sh), respectively. By equating 14R with 14sh and 14L (left) with 14Lo (long), the findings established a unified nomenclature for the arms of chromosome 14. Previously reported chromosome 14 arm locations were confirmed for four of the five translocations involving chromosome 14, namely NT1L-14L (2780), NT2R-14R (2B-1), NT14L-23R (2777), and NT14R-24R (2781), whereas the location of breakpoint T6L-14L was not confirmed and was reassigned to arm 14R. When used as a probe on Southern blots, the B77 signal was associated with a terminus of the D-subgenome RFLP linkage group (LG) D04 by linkage analysis of an interspecific F2 population, now known to be chromosome 20. However, additional codominant DNA marker information in the affected region excluded the B77 polymorphism detected by Southern blot hybridization from chromosome 20 and, indeed, from the remainder of the genome.
The effect of aluminium on bioelectrical activity of the Nitellopsis obtusa cell membrane after H+-ATPase inhibition
Authors: Kisnierienë Vilma , Sakalauskas Vidmantas 
Published: April 2007

AbstractAluminium induced membrane potential (Em) changes and potential changes during repolarization phase of the action potential (AP) in the internodal cells of Nitellopsis obtusa after blocking H+-ATPase activity by DCCD were investigated. Micromolar concentrations of DCCD are sufficient to give complete and irreversible inhibition of proton pumping. The membrane potential was measured by conventional glass-microelectrode technique. We found that the half-amplitude pulse duration differs significantly between standard conditions, after DCCD application, and after H+-ATPase blocking and subsequent Al3+ treatment: 4.9, 7.7 and 17.2 seconds, respectively. We propose that in the short term (2 hours) treatment of Al3+, the decrease in membrane potential was compensated for by H+-ATPase activity. Blocking H+-ATPase activity by DCCD can enhance the influence of Al3+ on the bioelectrical activity of cell membranes.
Structure of cyano-bridged Eu(III)—Co(III) bimetallic assembly and its application to photophysical verification of photomagnetic phenomenon
Authors: Akitsu T. , Einaga Y. 
Published: April 2007

AbstractNew crystal structure of Eu(DMF)4(H2O)3Co(CN)6·H2O (DMF = N,N′-dimethylformamide) (Eu-Co) has been determined to be monoclinic, P2(1)/n, a = 19.796(12) Å, b = 8.862(11) Å, c = 17.525(10) Å, β = 96.26(5)°, V = 3056(5) Å3, Z = 4. The Eu(III) ion adopts an antiprismatic eight-coordination and forms a cyano bridge with r(Eu-N) = 2.496(7) Å and Θ(Eu-N-C) = 165.7(7)° to the Co(III) ion. The complex exhibits some common features with the Eu-Fe complex. Diffuse reflectance electronic spectra and magnetic susceptibility of Eu-Cr, Eu-Mn, Eu-Fe, and Eu-Co complexes were compared. By substituting the metal ions, both electronic and structural features affected the charge transfer bands and superexchange interactions concerning cyanide ligands. In addition, only Eu-Co exhibited 5 D 0 → 7 F 2 and 5 D 0 → 7 F 1 luminescence bands at 16300 cm−1 and 16900 cm−1, respectively at 298 K (λex = 360 nm (27000 cm−1)), because quenching by cyano-bridged ions did not prevent Eu(III) ion from exhibiting emission. Thus, only Eu-Co may be suitable for verification of an assumption of mechanism concerning drastic photoinduced magnetic changes for Nd-Fe. Merely small decrease of magnetization was observed for Eu-Co after UV light irradiation at 2.0 K. This result was attributed to slight structural changes around cyano bridges without transitions of spin states.
Improved DPPH determination for antioxidant activity spectrophotometric assay
Authors: Szabo M. , Idiţoiu C. , Chambre D. , Lupea A. 
Published: April 2007

AbstractAn improved procedure for determination of the residual DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical concentration was proposed taking into account the absorbance of both DPPH free radicals and DPPH nonradical (1,1-diphenyl-2-picrylhydrazine) stable form. The calculated residual DPPH free radical concentrations were compared with those obtained from a calibration curve and variation coefficients below 10 % were found.
Synthesis of new condensed and cyclized coumarin derivatives
Authors: Dekić S. , Dekić V. , Dekić B. , Dekić M. 
Published: April 2007

AbstractCondensation of 4-chloro-2-oxo-2H-chromene-3-carbonitrile with selected heteroarylamines in acetonitrile containing a catalytic amount of triethylamine, followed by intramolecular cyclization, gave the new coumarin derivatives with yields ranging from 43 % to 78 %. The novel compounds were subjected to acid hydrolysis giving the corresponding oxo derivatives in 66–70 % yield. The structural assignments of the synthesized compounds were based on elemental, IR, 1H and 13C NMR analyses.
Manipulating power can affect memory conformity
Authors: Skagerberg Elin M. , Wright Daniel B. 
Published: March 2007

AbstractMemory is malleable and open to influence between encoding and retrieval. Information about a past event given to us by, for example, a co‐witness can be incorporated into our own memory reports. Pairs of participants were shown 50 photographs of faces, given a power task where one had to be a designer (low‐power) and one a judge (high‐power), and then given a recognition test where one partner had to answer before the other. The individuals in the low‐power group were more influenced by their partner's responses than those in the high‐power group. This has important forensic, educational and organisational applications and shows that memory conformity can be manipulated by power. Copyright © 2007 John Wiley & Sons, Ltd.
Covalent Modification of Glassy Carbon Electrode with Aspartic Acid for Simultaneous Determination of Hydroquinone and Catechol
Authors: Wang Liang , Huang Peng‐fei , Wang Hong‐jing , Bai Jun‐yue , Zhang Li‐ying , Zhao Yu‐qing 
Published: April 2007

AbstractGlassy carbon electrode (GCE) is covalently modified with aspartic acid (Asp). The modified electrode is used for the simultaneous electrochemical determination of hydroquinone (HQ) and catechol (CC) and shows an excellent electrocatalytical effect on the oxidation of HQ and CC by cyclic voltammetry (CV) in 0.1 mol/L acetate buffer solution (pH 4.5). In differential pulse voltammetric (DPV) measurements, the modified electrode could separate the oxidation peak potentials of HQ and CC present in binary mixtures by about 101 mV though the bare electrode gave a single broad response. A successful elimination of the fouling effect by the oxidized product of HQ on the response of CC has been achieved at the modified electrode. The determination limit of HQ in the presence of 0.1 mmol/L CC was 9.0 × 10‐7 mol/L and the determination limit of CC in the presence of 0.1 mmol/L HQ was 5.0 × 10‐7 mol/L. The proposed method has been applied to the simultaneous determination of HQ and CC in a water sample with simplicity and high selectivity.
Nutritional status of Ribeirinhos in Brazil and the nutrition transition
Authors: Piperata Barbara A. 
Published: April 2007

AbstractAnthropometric and household data (size, composition, economic activity) were collected from a population of Ribeirinhos living in a rural setting in the eastern Amazon. Data are compared to international reference standards and to other Amazonian populations with the goals of increasing our understanding of the Amazon's largest ethnic group and identifying the relationship between changes in subsistence strategies and nutritional status. Data on height, weight, skinfolds, and circumferences were collected from 471 adults and subadults. The population showed a high degree of stunting with an average HAZ below −2.0 for all age groups over 3 years, and 60% of adult men and 70% of adult women were stunted. Wasting was rare. Average skinfold thicknesses and upper‐arm muscle area were near or below average but within the normal range compared to the reference standard, indicating adequate energy and protein stores. Thirty‐one percent of males and 29% of females were overweight/obese, and the highest average BMIs were found among men and women in their 40s. Adult males who participated in wage labor had higher weights, BMIs, and UMA values, and were more likely to be overweight and obese compared with those who did not work in wage‐labor jobs. Children of fathers who worked in wage labor had higher BMI and UMA values, but there was no significant effect on the nutritional status of other adults in these same households. Signs of the nutrition transition were most noticeable among adult males involved in wage labor because of changes in their diet and activity patterns.

The Enantioselective Morita–Baylis–Hillman Reaction and Its Aza Counterpart
Authors: Masson Géraldine , Housseman Christopher , Zhu Jieping 
Published: April 2007

AbstractThe development of asymmetric Morita–Baylis–Hillman (MBH) reactions has evolved dramatically over the past few years, parallel to the emerging concept of bifunctional organocatalysis. Whereas organocatalysis is starting to compete with metal‐based catalysis in several important organic transformations, the MBH reaction belongs to a group of prototypical reactions in which organocatalysts already display superiority over their metal‐based counterparts. This Minireview summarizes recent mechanistic insights and advances in the design and synthesis of small organic molecules for enantioselective MBH and aza‐MBH reactions.
Solvent‐free cyanosilylation of ketones with (CH3)3SiCN (TMSCN) catalyzed by NbF5
Authors: Kim Sung Soo , Rajagopal Gurusamy , George Soney C. 
Published: April 2007

AbstractThe addition of TMSCN to ketones catalyzed by dispersed NbF5 gave corresponding cyanohydrin trimethylsilylethers with excellent yield (>90%). Cyano transfer occurs within 30 min at room temperature in the presence of 1 mol% of NbF5 under solvent‐free conditions. These conditions are extremely mild, simple, and tolerate various functional groups. Copyright © 2007 John Wiley & Sons, Ltd.
Preparation and characterization of castor oil‐based polyurethane/poly(o‐methoxyaniline) blend film
Authors: Alves William F. , Kanda Darcy H. F. , Malmonge Luiz F. , Malmonge José A. , Mattoso Luiz H. C. 
Published: April 2007

AbstractBlends made up of castor oil‐based polyurethane (PU) and poly(o‐methoxyaniline) (POMA) were obtained in the form of films by casting and characterized by FTIR, UV‐Vis‐NIR spectroscopy, and electrical conductivity measurements. Doping was carried out by immersing the films in 1.0M HCl aqueous solution. Chemical bonds between NCO group of PU and NH group of POMA were observed by means of FTIR spectra. The UV‐Vis‐NIR spectra indicated that the presence of the PU in the blend does not affect doping and formation of the POMA phase. The electrical conductivity research was in the range of 10−3 S/cm. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
N‐(4‐(4‐(2‐Halogenophenyl)piperazin‐1‐yl)butyl) Substituted Cinnamoyl Amide Derivatives as Dopamine D2 and D3 Receptor Ligands
Authors: Saur Oliver , Hackling Anneke E. , Perachon Sylvie , Schwartz Jean‐Charles , Sokoloff Pierre , Stark Holger 
Published: April 2007

AbstractA series of eight substituted N‐(4‐(4‐(2‐halogenophenyl)piperazin‐1‐yl)butyl)‐3‐phenylacryl amide derivatives have been synthesized and screened for binding affinities at dopamine hD2 and hD3 receptors. All compounds have shown high to remarkable receptor affinities and some have led to distinct selectivity for D3 receptors. Highest D3‐receptor affinity has been observed for 3‐(4‐aminophenyl)‐N‐(4‐(4‐(2‐fluorophenyl)piperazin‐1‐yl)butyl)acryl amide (hD3 Ki 0.9 nM; hD2 Ki 17.4 nM). Selectivity ratio has been best for 3‐(4‐chlorophenyl)‐N‐(4‐(4‐(2‐fluorophenyl)piperazin‐1‐yl)butyl)acryl amide with a 56‐fold preference for hD3 versus hD2. A functional activity test has been performed by a mitogenesis test for N‐(4‐(4‐(2‐fluorophenyl)piperazin‐1‐yl)butyl)‐3,3‐diphenylacryl amide, which, surprisingly, has shown full agonist properties.
Environmental management and strategy in the face of regulatory intensity: radioactive contamination in the US steel industry
Authors: Clemens Bruce Wayne , Papadakis Maria 
Published: April 2007

AbstractRecent business literature argues that several incentives drive firms to cooperate with government environmental regulators and regulation without pressure from the government. This study explores and tests such arguments using a metric called regulatory intensity. The study uses survey data from the radioactive scrap metal industry. The findings challenge the recent literature that ‘going green pays’. The study found that strong government actions (regulatory intensity) are related to firm cooperation. Firms seem to adopt cooperative strategies when coerced to do so by the government. Copyright © 2007 John Wiley & Sons, Ltd and ERP Environment.
Football hooliganism: comparing self‐awareness and social identity theory explanations
Authors: Van Hiel Alain , Hautman Lobke , Cornelis Ilse , De Clercq Barbara 
Published: March 2007

AbstractThe emergence of research interest in group violence in general and football hooliganism in particular has been explained by various models generally relying on situational or individual differences accounts. Yet, these two research traditions have largely evolved independently, showing little or no interaction. In the present study (N = 109), we integrate measures of these two approaches and the results reveal that social identity was more predictive of self‐reported physical aggression than of loss of private and public self‐awareness. Moreover, attitudes towards violence were the most marked predictor variables of both physical and verbal aggression. In the discussion, the moderator effect of social identity and attitudes about violence on physical aggression is elaborated upon. Copyright © 2007 John Wiley & Sons, Ltd.
