AbstractWe report on the synthesis and characterization of new sila‐ and germa‐thiazolidines derived from 2‐[1‐(1‐naphthyl)ethyl]‐2‐imidazoline. The radioprotective activity was evaluated in mice by intraperitoneal injection. A notable diminution in the toxicity and increase in radioprotective efficacy were shown for the organometallic derivatives compared with the unsubstituted organic precursors. For some of the cyclic compounds, a delay effect was observed tranducing a slow opening in vivo of the thiazolidine ring. Copyright © 2004 John Wiley & Sons, Ltd.

Published: May 2004

AbstractTemperature heterogeneity along the inner surface of an artery may be a surrogate marker of impending plaque rupture and has been associated with an increased likelihood of future coronary events. Initial studies using catheter‐based thermographic devices have demonstrated that the changes in temperature are subtle, while the effects of coronary flow on measured temperature have not yet been examined. A novel guidewire‐based system (ThermoCoil, Imetrx) designed to measure surface temperature in coronary arteries was used to study the effects of heat source intensity and flow on measured temperature. An in vitro model of a focal, eccentric, heat‐generating lesion demonstrated that a guidewire‐based system can detect changes in surface temperature with a precision of less than 0.08°C. In this model, temperature measurements increased linearly with source temperature and decreased with increases in flow by an exponent of −0.33 (P < 0.001 for both). Flow rates and heat source properties can significantly influence the measurement and interpretation of thermographic data. The incorporation of 2D thermographic images may contribute further to the characterization of metabolically active plaques likely to cause acute coronary syndromes.

Numerical analysis of electromagnetic scattering from 3D dielectric objects using the Yasuura method
Authors: Koba Koichi , Ikuno Hiroyoshi , Kawano Mitsunori 
Published: May 2004

AbstractIn order to calculate 3D electromagnetic scattering problems by dielectric objects which we need to solve a large‐size simultaneous linear equation, we present a rapid algorithm on the Yasuura method where we accelerate the convergence rate of solution by using an array of multipoles as well as a conventional multipole. As a result, we can obtain the radar cross sections of dielectric objects in the optical wave region over a relatively wide frequency range and a TDG pulse response. Furtherrmore, we analyze the scattering data about dielectric objects by using the pulse responses cut by an appropriate window function in the time domain and clarify the scattering processes on dielectric objects. © 2004 Wiley Periodicals, Inc.

Authors: Yamamoto Hiroshi , Ooi Tetsuya 
Published: May 2004

AbstractExperiments were carried out to investigate the magnetic properties of Sm‐Fe‐Co‐W‐Cr system nitriding compounds with TbCu7‐type structure. Sm10(Fe0.95−Co0.05)89.7−xW0.3Crx(x = 0 − 0.7) alloy ribbons were prepared by the single roller rapid‐quenching method, and the effects of alloy composition, and conditions of heat‐treatment and nitrogenation, were examined with regards to their magnetic properties. The optimum preparation conditions of the compounds are as follows. Composition: {Sm10(Fe0.95Co0.05)89.4W0.3Cr0.3}85.0 N15.0, roller velocity: 50 m/s, heat treatment: 675 °C × 60 min in high‐purity Ar gas, and nitriding conditions: 420 °C × 10 h in high‐purity N2 gas. Typical magnetic properties of the obtained compound powders are στ = 123.7 × 10−6 Wb · m/kg, HcJ = 706.0 kA/m, (BH)max = 139.4 kJ/m3 (17.4 MGOe), and Tc = 508 °C. It was found that this sample was an exchange spring magnet from TEM photographs and recoil loops of the hysteresis curve. The value of (BH)max for the compression molding isotropic bonded magnet prepared from the {Sm10(Fe0.95Co0.05)89.4W0.3Cr0.3}85.0 N15.0 powder is 102.9 kJ/m3 (12.9 MGOe), when the density of bonded magnet is 6.1 Mg/m3. The reversible temperature coefficient of Jτ is α(Jτ = −0.07%/°C, and the temperature coefficient of HcJ in the range of 25 °C to 125 °C obtained by a linear extrapolation is α(HcJ) = −0.44%/°C. © 2004 Wiley Periodicals, Inc.

Voltammetric Determination of α‐Tocopheryl Acetate in Pharmaceutical Dosage Forms
Authors: Michalkiewicz Slawomir , Pryciak Marzena , Malyszko Jan , Oszczudlowski Jerzy 
Published: May 2004

AbstractA simple and rapid voltammetric method has been developed for the quantitative determination of α‐tocopheryl acetate (α‐TOAc) in pharmaceutical preparations. Studies with linear scan (LSV), square‐wave (SQWV) and differential pulse voltammetry (DPV) were carried out using platinum microelectrodes. A well‐defined, irreversible oxidation wave/peak was obtained at 1.30 V (vs. Ag/AgCl reference electrode.) The use of SQWV or DPV technique provides a precise determination of α‐tocopheryl acetate using the multiple standard addition method. The statistical parameters and the recovery study data clearly indicate good reproducibility and accuracy of the method. Accuracy of the results assessed by recovery trials was found within the 99.3% to 103.5%, and 99.1% to 101.4%, for SQWV and DPV, respectively. The quantification limits for the both voltammetric techniques were found to be 6×10−5 M (SQWV) and 7×10−5 M (DPV). Analysis of the authentic samples containing α‐TOAc showed no interference with common additives and excipients, such as unsaturated fatty acids (co‐formulated as glycerine esters) and vitamin A (as retinol or β‐carotene). The method proposed does not require any pretreatment of the pharmaceutical dosage forms. A gas chromatography determination of α‐TOAc in real samples was also performed for comparison.
Nucleotide sequence analysis of the recA gene and discrimination of the three isolates of urease‐positive thermophilic Campylobacter (UPTC) isolated from seagulls (Larus spp.) in Northern Ireland

Published: May 2004

AbstractNucleotide sequencing after TA cloning of the amplicon of the almost‐full length recA gene from three strains of UPTC (A1, A2, and A3) isolated from seagulls in Northern Ireland, the phenotypical and genotypical characteristics of which have been demonstrated to be indistinguishable, clarified nucleotide differences at three nucleotide positions among the three strains. In conclusion, the nucleotide sequences of the recA gene were found to discriminate among the three strains of UPTC, A1, A2, and A3, which are indistinguishable phenotypically and genotypically.Thus, the present study strongly suggests that nucleotide sequence data of the amplicon of a suitable gene or region could aid in discriminating among isolates of the UPTC group, which are indis‐ tinguishable phenotypically and genotypically.

Production of lignocellulolytic enzymes by Trametes gallica and detection of polysaccharide hydrolase and laccase activities in polyacrylamide gels
Authors: Sun Xun , Zhang Renhuai , Zhang Yizheng 
Published: May 2004

AbstractWhite rot fungus Trametes gallica was studied for the production of lignocellulolytic enzymes: cellulase, xylanase, laccase, manganese‐dependent peroxidase (MnP), and lignin peroxidase (LiP). The results demonstrated that low‐nitrogen (2.2 mM N) and surface stationary cultivation favored production of extracellular MnP. MnP activity reached 118.1 UL–1 while T. gallica was grown in a low‐nitrogen culture containing phenylalanine. However, Laccase levels observed in high‐nitrogen (22 mM N) agitated cultures were much greater than those seen in low‐nitrogen. The N source experiments seemed to reveal that NH4+ plays an important role in inducing MnP and laccase of the fungus. Results showed that T. gallica produces a series of the lignocellulolytic enzymes, and needs high N to produce all the enzymes during solid‐state fermentation of wheat straw. This paper also presents a modified zymogram procedure to detect xylanase and laccase of T. gallica in polyacrylamide gel. Xylanase in crude enzyme of T. gallica was displayed by contacting protein gel strips with xylan substrate gels and by staining with iodine. By immersing the protein gel strips in o‐tolidine solution, the blue‐green zones representing laccase activity were visualized against a colorless background. (© 2004 WILEY‐VCH Verlag GmbH & Co.

Lengthy Rod Formation from a Poly(oxyalkylene)amine‐Intercalated Smectite Clay by a Self‐Aligning Mechanism
Authors: Lin Jiang‐Jen , Chou Chih‐Cheng , Lin Jen‐Lien 
Published: May 2004

AbstractSummary: A micrometer rod morphology was produced by self‐assembly of poly(oxypropylene)amine (POP‐amine) modified montmorillonite. The requisite primary structure was prepared by intercalation of the layered clay with POP‐amine salts. During the drying process, the primary units self‐assemble into micro‐rods that are 100–800 nm wide and 2–40 μm long. The stacking process may involve two complimentary forces – the POP hydrophobic effect and the silicate ionic interaction – acting in separate directions.Lengthy rod formation from Poly(oxyalkylene)amine‐intercalated smectite clay.imageLengthy rod formation from Poly(oxyalkylene)amine‐intercalated smectite clay.

Multiwavelength fiber laser using a multimode elliptical‐core erbium‐doped fiber
Authors: Das Gautam , Lit John W. Y. 
Published: May 2004

AbstractThis paper reports on a fiber laser constructed with an erbium‐doped fiber, which has an elliptical core that is single‐moded along the minor axis and multimoded along the major axis. The laser can simultaneously emit several stable lines at room temperatures. The maximum number of lasing lines obtained depends on the number of modes supported by the erbium‐doped fiber in the cavity. The separation between the lasing lines depends on the fiber birefringence. The principle of operation is based on the anisotropic‐gain effects in a polarization‐maintaining fiber. The stability of the lasing lines, in the presence of anisotropic‐gain effects in a polarization‐maintaining fiber, has been explored. © 2004 Wiley Periodicals, Inc.

Efficient evaluation of macro‐basis‐function reaction terms in the subdomain multilevel approach
Authors: Stevanović Ivica , Mosig Juan R. 
Published: May 2004

AbstractThis paper presents an improved subdomain multilevel approach (SMA), a technique efficiently used for solving large complex‐shaped antennas printed in multilayered media structure. In a large electromagnetic problem, where the memory occupation and computational time have been already significantly reduced using the SMA, the calculation of the macro basis function (MBF) reaction terms remains the most time‐consuming part of the procedure. In this paper, we present an efficient way of computing MBF reaction terms and reducing them to equivalent moments. The numerical results are compared with brute‐force computations, the SMA, and the measurements. They demonstrate conclusively the efficiency and power of the new proposed technique. © 2004 Wiley Periodicals, Inc.

Published: May 2004

AbstractA new circular‐polarization (CP) design of an annular‐ring microstrip antenna operating at the fundamental TM11 mode is presented. The CP radiation of the proposed design is achieved by connecting an L‐shaped strip to two orthogonal sides of the inner boundary of the annular‐ring patch. A prototype of the proposed antenna fabricated on a foam substrate has been implemented and studied. The results show that good CP‐radiation performances are obtained and the 3‐dB axial ratio is about 2%. Good agreement is also obtained between the measured and simulated results. © 2004 Wiley Periodicals, Inc.

Assessment of cortical gyrus and sulcus formation using magnetic resonance images in small‐for‐gestational‐age fetuses
Authors: Abe Seiji , Takagi Kenjiro , Yamamoto Tatsuo , Kato Toshinori 
Published: May 2004

AbstractObjectivesThe purpose was to compare the development of gyrus and sulcus formation (GSF), an indicator of brain maturation, in small‐for‐gestational‐age (SGA) fetuses using magnetic resonance (MR) imaging, with those of appropriate‐for‐gestational‐age (AGA) fetuses.MethodsThe 160 infants with a normal neurological outcome were divided into two groups on the basis of their body weight at delivery; 37 SGA infants (Group SGA) and 123 AGA infants (Group AGA). Fetal MR images, which were obtained from 28 to 39 gestational weeks in Group SGA and from 18 to 39 gestational weeks in Group AGA, were classified into the 8 stages of development for GSF established by Abe et al. (2003), and comparison was made between the two groups retrospectively in their neurological development in relation to gestational age.ResultsIn Group SGA, images were classified into stages 3 to 8 (P < 0.001). The gestational age of the cases determined for each stage between Groups SGA and AGA did not differ significantly, with respect to the development of GSF, despite differences in fetal estimated body weights.ConclusionIn SGA fetuses, evaluation of fetal GSF using MR images during the third trimester may be useful for predicting neurological prognoses postpartum.

Temperature‐dependent polymer–polymer interactions in polystyrene–polyethylene blends
Authors: Banik Indranil , Carreau Pierre J. , Schreiber Henry P. 
Published: May 2004

AbstractThe effect of the temperature on the interaction between the components of an immiscible polystyrene–polyethylene blend has been analyzed with different techniques. Lap‐shear‐strength data and morphological observations indicate an enhanced interaction between the polymeric phases at elevated temperatures, at which dispersive forces are known to predominate. This raises the degree of compatibility of the polymeric components. Rheological measurements also justify the concept of increased adhesion between the components of the blend when it is processed at very high temperatures. Differential scanning calorimetry analysis lends support to an improved homogeneity of the blend at an elevated temperature; this is again consistent with an improved interaction between the blend phases. © 2004 Wiley Periodicals, Inc.

Dopamine D4 receptor‐deficient mice, congenic on the C57BL/6J background, are hypersensitive to amphetamine
Authors: Kruzich Paul J. , Suchland Katherine L. , Grandy David K. 
Published: May 2004

AbstractMice lacking the dopamine D4 receptor subtype (D4R−/−) are supersensitive to methamphetamine and cocaine. We sought to expand and refine earlier experiments performed on F2 generation D4R−/− mice by lengthening the behavioral session, utilizing an N10 D4R−/− incipient congenic C57BL/6J line (D4R−/− mice backcrossed with wildtype C57BL/6J mice for 10 successive generations), and investigating whether dopamine D4Rs are necessary for the expression of behavioral sensitization to amphetamine. The D4R−/− mice demonstrated an enhanced and dose‐dependent increase in amphetamine‐stimulated activity compared to wildtype mice following acute administrations of amphetamine. For the behavioral sensitization experiments, separate groups of mice received either repeated administrations of the same dose of amphetamine or a subthreshold dose of amphetamine (2 mg/kg) 28 days following pretreatment with either saline, 1.0, 3.0, or 10.0 mg/kg amphetamine. The D4R−/− mice displayed an enhanced dose‐dependent sensitized response to repeated amphetamine administrations compared to their wildtype littermates in both behavioral sensitization paradigms. Our present results further support the importance of dopamine D4Rs in psychostimulant‐mediated locomotion and neural plasticity. Synapse 53:131–139, 2004. © 2004 Wiley‐Liss, Inc.
