Development of microsatellite markers in Capsella rubella and Capsella bursa‐pastoris (Brassicaceae)
Authors: Caullet Coraline M. L. , Pernin Fanny , Poncet Charles , Le Corre Valérie 
Published: June 2011

• Premise of the study: We developed microsatellite markers to investigate genetic diversity within and among populations of Capsella rubella and Capsella bursa‐pastoris and between these two species.• Methods and Results: Fourteen polymorphic microsatellite loci were identified in the two species and one more polymorphic microsatellite locus only in C. rubella. Samples from different European localities were genotyped. Up to six alleles per locus were observed in C. rubella, and up to 22 alleles per locus in C. bursa‐pastoris. Observed heterozygosities were low, indicating high selfing rates, especially in C. rubella.• Conclusions: The results provide valuable information on genetic diversity for future studies of population genetics in C. rubella and C. bursa‐pastoris.

Published: June 2011

• Premise of the study: Microsatellite primers were developed for Bothriochloa ischaemum to investigate the structure of invasive populations within Texas and determine the origin of introduction from within the native range.• Methods and Results: We adapted the biotinylated nucleotide method of developing an enriched genomic library to isolate and characterize 10 polymorphic microsatellite markers. The number of alleles per locus (A) ranged from five to 18 (mean A = 10.45), expected heterozygosity (HE) ranged from 0.620 to 0.895 (mean HE = 0.785), and expected heterozygosity corrected for sample size (HEC) ranged from 0.635 to 0.909 (mean HEC = 0.799). The primers were also tested for amplification in Schizachyrium scoparium var. scoparium, Andropogon gerardii, Bothriochloa saccharoides, and Dichanthium annulatum.• Conclusions: The use of microsatellite markers may assist in understanding the pattern of spread, determining the source of invasive populations, and developing biological control agents for invasive populations of Bothriochloa ischaemum.
Almost Everywhere Convergence of Convolution Measures

Published: June 2011

AbstractLet (X, ℬ, m, τ) be a dynamical system with (X, ℬ, m) a probability space and τ an invertible, measure preserving transformation. This paper deals with the almost everywhere convergence in L1(X) of a sequence of operators of weighted averages. Almost everywhere convergence follows once we obtain an appropriate maximal estimate and once we provide a dense class where convergence holds almost everywhere. The weights are given by convolution products of members of a sequence of probability measures {vi} defined on ℤ. We then exhibit cases of such averages where convergence fails.

Published: June 2011

Purpose The purpose of this study was to perform bench and clinical testing of a catheter-based intravascular system capable of measuring blood flow in hemodialysis vascular accesses during endovascular procedures. Methods We tested the Transonic ReoCath Flow Catheter System which uses the thermodilution method. A simulated vascular access model was constructed for the bench test. In total, 1960 measurements were conducted and the results were used to determine the accuracy and precision of the catheters, the effects of external factors (e.g., catheter placement, injection duration), and to test for systematic bias. In the clinical study, two interventional radiologists conducted a total of 250 measurements in 14 patients with arteriovenous fistulas to determine clinical precision and enable testing for bias between measurers. Results Accuracy was excellent for both catheters with a high level of agreement between results from the ReoCath Flow Catheter System and the reference flowmeter. Clinical precision, expressed as the mean coefficient of variation, was 5.9% and 4.7% for the antegrade and retrograde catheters, respectively. Flow measurements were significantly affected by the distance between a stenosis and the tip of a retrograde catheter with the effect being proportional to the degree of stenosis. There was no systematic bias between measurers. Conclusions The Reocath Flow Catheter System was found to be accurate and precise. Reliable results require careful attention to catheter placement. Blood flow measurements provide unique information on the hemodynamic status of a vascular access and have the potential to optimize results of interventions.

Published: June 2011

AbstractStevens‐ Johnson syndrome (SJS) is a severe and life‐threatening condition. Although allopurinol, an antihyperuricemia drug, is the drug most commonly associated with SJS, more than 100 different causative drugs have been reported. Among hematologic drugs recently introduced into the market, drugs such as rituximab, imatinib, and bortezomib are reported. Here, we describe a patient with SJS while receiving lenalidomide in combination with prednisolone for treatment‐naïve multiple myeloma. Although SJS has been reported rarely as an adverse reaction to Lenalidomide, this drug should be considered in the etiology of SJS, and the increased number of prescriptions of Lenalidomide for the therapy of multiple myeloma has to stress the awareness of its potentially serious side‐effects.

Published: June 2011

AbstractBACKGROUND: Previous studies have shown that resistance of Botrytis cinerea to QoI fungicides has been attributed to the G143A mutation in the cytochrome b (cytb) gene, while, in a part of the fungal population, an intron has been detected at codon 143 of the gene, preventing QoI resistance. During 2005–2009, 304 grey mould isolates were collected from strawberry, tomato, grape, kiwifruit, cucumber and apple in Greece and screened for resistance to pyraclostrobin and for the presence of the cytb intron, using a novel real‐time TaqMan PCR assay developed in the present study.RESULTS: QoI‐resistant phenotypes existed only within the population collected from strawberries. All resistant isolates possessed the G143A mutation. Differences were observed in the genotypic structure of cytb. Individuals possessing the intron were found at high incidence in apple fruit and greenhouse‐grown tomato and cucumber populations, whereas in the strawberry population the intron frequency was lower. Cultivation of QoI‐resistant and QoI‐sensitive isolates for ten culture cycles on artificial nutrient medium in the presence or absence of fungicide selection showed that QoI resistance was stable.CONCLUSIONS: The results of the study suggest that a high risk for selection of QoI‐resistant strains exists in crops heavily treated with QoIs, in spite of the widespread occurrence of the cytb intron in B. cinerea populations. The developed real‐time TaqMan PCR constitutes a powerful tool to streamline detection of the mutation by reducing pre‐ and post‐amplification manipulations, and can be used for rapid screening and quantification of QoI resistance.

Thermal stability and electrical properties of Se90Ge10‐xInx amorphous alloys
Authors: Abo Ghazala M. S. , Aboelhasn E. , Amar A. H. , Gamel W. 
Published: June 2011

AbstractBulk glasses of Se90Ge10‐xInx(where x = 2, 4 and 6 at.%) were prepared using a conventional rapid quenching technique. The amorphous nature and the crystalline phases of the samples annealed at 393 K for 25 h were investigated using X‐ray diffraction. Calorimetric analysis of the bulk glassy samples has been carried out using differential scanning calorimetric (DSC) under non‐isothermal condition. It was found that these glasses exhibit double glass transitions and double‐stage crystallization transitions on heating. The glass transition temperature, Tg and the crystallization transformation temperature, Tc were found to be dependent on the composition and heating rates. The activation energy for glass transition (Eg) and that for crystallization (Ec) were evaluated using different empirical approaches and their composition dependence was discussed. The results revealed that the activation energy of crystallization, Ec increases with rising the In content. The electrical resisitivity of the prepared glasses was measured as a function of temperature and annealing time. It was found that the activation energy of conduction deduced from the temperature dependence of the resistivity increases with increasing the In content. On the other hand it was found that the activation energy of crystallization deduced from the annealing time dependence of the resistivety using Avrami's equation is compositional dependent.

Raman and DSC studies of fragility in tellurium‐zinc oxide glass formers
Authors: Stavrou Elissaios , Kripotou Sotiria , Raptis Constantine , Turrell Sylvia , Syassen Karl 
Published: June 2011

AbstractRaman scattering and differential scanning calorimetry (DSC) measurements have been carried out in four mixed (TeO2)1‐x(ZnO)x (x = 0.1, 0.2, 0.3, 0.4) glasses at high temperatures (Raman and DSC through the glass transition) and high pressures (Raman) with the aim of determining the fragility of these glass forming oxides. Four different criteria, corresponding to four parameters, were applied to assess the fragility of the glasses. From the DSC studies, we have obtained the fragility parameter m which corresponds to the slopes of Arrhenius (lnQ vs. 1/Tg, were Q is the heating rate) plots, and the glass transition width ΔTg. Also, from the low‐frequency Raman scattering, and in particular the boson peak intensity of the glasses at Tg, we have estimated the fragility ratio rR (Tg) = Imin/Imax whose value serves as another (empirical) fragility criterion. Finally, from high pressure Raman measurements on the glasses, we have estimated the Grüneisen parameter γT for each glass, which constitutes the fourth fragility parameter adopted in this work. Considering the four parameters ΔTg, m, r (Tg) and γT and the generally accepted (empirical) fragility criteria, we conclude that the mixed tellurium‐zinc oxides constitute strong‐to‐intermediate glass formers (© 2011 WILEY‐VCH Verlag GmbH & Co.

Effect of temperature and frequency of dynamic loading in the viscoelastic properties of aluminium alloy 7075‐T6
Authors: Rojas Jose I. , Aguiar Albert , Crespo Daniel 
Published: June 2011

AbstractThe viscoelastic response of a material offers an alternative method for analyzing its microstructure, phase transformations and fatigue behaviour. In this work, the viscoelastic properties of commercial aluminium alloy (AA) 7075‐T6 are studied with a Dynamic‐Mechanical Analyzer (DMA), and results are combined with Transmission Electron Microscopy (TEM) and Differential Scanning Calorimetry (DSC) data. In accordance with this analysis, we propose an analytical model for the storage modulus E ' as a function of temperature, frequency of the dynamic loading and the concentration of Guinier‐Preston Zones (GPZ). The latter parameter is obtained as a function of temperature after integration and fitting of the model. It is shown that the proposed model fits the experimental data for the storage modulus reasonably well in the prescribed region, and that this fact supports the hypothesis that the change in the storage modulus slope at about 130‐160 °C is due to GPZ decomposition.

Influence of Ba2+ ions on defect concentration in bismuth silicate glasses evidenced by FTIR and UV‐visible spectroscopy
Authors: Ahlawat Neetu , Agarwal Ashish , Sanghi Sujata , Ahlawat Navneet 
Published: June 2011

AbstractBismuth silicate glasses containing Ba2+ ions were prepared by a normal melt quench technique in a wide range of composition. The present study includes structural and optical characterization of these glasses by using the techniques of IR and UV‐visible spectroscopy. The variation in density and molar volume with Ba2+ ion concentration was related to structural changes occurring in the glass. The large difference in crystalline temperature (TC) and glass transition temperature (Tg) value shows the thermal stability of these glasses. Analysis of IR spectra shows the occurrence of broad and strong band around 456‐471 cm‐1, attributed to both Bi‐O‐ stretching vibrations in distorted linked [BiO6] units and bending vibrations of the silicate network. The shifting of center of the band around 800 ‐ 1100 cm‐1 with the increase in Ba2+ ions concentration in glass matrix suggests a decrease in Si‐O‐Si bond angle and causes glass network shrinkage which is also supported by observed decrease in molar volume. The analysis of optical absorption spectra of these glasses reveals that the position of absorption edge and cutoff wavelength shift towards blue as Ba2+ ion concentration increases in the glass composition. The variation in optical band gap energy (Eg) with change in glass composition may be attributed to the indirect influence of the Ba2+ ions on the band gap and can be evaluated from the Tauc's plots for indirect allowed and indirect forbidden transitions. The increase in optical band gap (Eg) from optical absorption analysis indicates that the glass network becomes more compact and degree of disorder decreases with increase of concentration of Ba2+ ions. The origin of Urbach's energy is associated with phonon‐assisted indirect transitions and its value varies with the random internal electric field either due to lack of long range order or presence of defects. From Urbach energy values, it was concluded that the defect concentration could be controlled by the presence of Ba2+ ions in the present glass system (© 2011 WILEY‐VCH Verlag GmbH & Co.

Research planning for the future of psychiatric diagnosis
Authors: Regier D.A. , Kuhl E.A. , Narrow W.E. , Kupfer D.J. 
Published: June 2011

AbstractMore than 10 years prior to the anticipated 2013 publication of DSM-5, processes were set in motion to assess the research and clinical issues that would best inform future diagnostic classification of mental disorders. These efforts intended to identify the clinical and research needs within various populations, examine the current state of the science to determine the empirical evidence for improving criteria within and across disorders, and stimulate research in areas that could potentially provide evidence for change. In the second phase of the revision process, the American Psychiatric Institute for Research and Education (APIRE) recently completed the 5-year international series of 13 diagnostic conferences convened by APA/APIRE in collaboration with the World Health Organization and the National Institutes of Health (NIH), under a cooperative grant funded by the NIH. From these conferences, the DSM-5 Task Force and Work Groups have developed plans for potential revisions for DSM-5, including the incorporation of dimensional approaches within and across diagnostic groups to clarify heterogeneity, improve diagnostic validity, and enhance clinical case conceptualization. Use of dimensions for measurement-based care has been shown to be feasible in psychiatric and primary care settings and may inform monitoring of disorder threshold, severity, and treatment outcomes. The integration of dimensions with diagnostic categories represents an exciting and potentially transformative approach for DSM-5 to simultaneously address DSM-IV's clinical short-comings and create novel pathways for research in neurobiology, genetics, and psychiatric epidemiology.
The effects of self‐brand connections on responses to brand failure: A new look at the consumer–brand relationship
Authors: Cheng Shirley Y.Y. , White Tiffany Barnett , Chaplin Lan Nguyen 
Published: June 2011

AbstractWe argue that consumers with high self‐brand connections (SBC) respond to negative brand information as they do to personal failure — they experience a threat to their positive self‐view. After viewing negative brand information, high (vs. low) SBC consumers reported lower state self‐esteem. Consumers with high SBC also maintained favorable brand evaluations despite negative brand information. However, when they completed an unrelated self‐affirmation task, they lowered their brand evaluations the same as low SBC consumers. This finding suggests that high SBC consumers' reluctance to lower brand evaluation might be driven by a motivation to protect the self rather than the brand.
The Sarkhoi Group in East Sayan: Neoproterozoic (~770–800 Ma) volcanic belt of the Andean type
Authors: Kuzmichev A.B. , Larionov A.N. 
Published: June 2011

Abstract
The Sarkhoi Group localized in the stratotype area is composed of various volcanics and volcanoclastics more than 4 km in total thickness. The volcanics of the lower part are greenschist facies altered rocks ranging from basalt to dacite, and those of the upper part are mainly rhyolitic ignimbrites. The composition, sequence, and facial features of these volcanics show their affinity to the active continental margin. This is confirmed by geochemical data evidencing the participation of the Early Precambrian continental crust in their formation. The U-Pb zircon dating (SHRIMP) of the Sarkhoi volcanics yielded the Neoproterozoic age of the ignimbrites (782 ± 11 Ma, concordant cluster N = 8). The tonalite-trondhjemites of the Sumsunur complex in the Gargan block are plutonic analogs of these volcanic rocks. Coeval granitoids were also revealed in other parts of the Tuva–Mongolian and Dzavhan massifs. The ~1500 km long Sarkhoi–Dzavhan volcanic belt is a fragment of the Neoproterozoic active continental margin separated from the continent. In the Middle Neoproterozoic, the geodynamic system also included the Oka accretionary prism joining the Sarkhoi continental margin and the Shishkhid island arc. Coeval analogs of the above structures are also reconstructed in the Yenisei Range and Baikal–Muya belt. This suggests that the Sarkhoi belt was initially localized along the margin of the Neoproterozoic Siberian continent. But the exotic origin of the Precambrian massifs in southern Siberia is not ruled out either.
Paleogene and Neogene stratigraphy and paleotemperature trend of West Siberia (from palynologic data)
Authors: Volkova V.S. 
Published: June 2011

Abstract
The paper discusses the Paleogene and Neogene stratigraphy of Siberia and estimates the paleotemperature and precipitation trends. The paleotemperatures were estimated on the basis of climatograms (V.P. Grichuk) and the analysis of temperatures in the ranges of the main plant genera. The Paleogene and Neogene temperatures were always high (at least 0° C). The average annual temperatures varied from +20 to +10 – +5 ºC, the winter temperature being from +10 to +5 – +3 °C. The precipitation varied from 1400–1000 mm/yr in the Paleocene and Eocene to 800–500 mm/yr in the Oligocene and 250–100 mm/yr in the Late Miocene. The climate cooled in the Late Eocene–Early Oligocene, Late Oligocene–Early Miocene, and Early Pliocene. Three stages of arid climate have been distinguished: one in the Late Miocene (7–5.5 Ma) and two in the Early Pliocene (Cherlak and Bitekei time). In the Late Pliocene (2.6 Ma, Kulunda Horizon), the cooling was slight. It gave rise to vegetation zones, which were distributed similarly to the present-day ones. The arctic flora migrated to the southern West Siberian Plain at 1.65–1.8 Ma (Ubinskoe–Erestnaya time), when the climate was close to a glacial one.
The lower boundary of the Toyonian stage (Cambrian) of the Siberian Platform
Authors: Korovnikov I.V. 
Published: June 2011

Abstract
The paper examines trilobite assemblages found in the Botomian–Toyonian (Lower Cambrian) boundary stratotype section in the middle reaches of the Lena River, Siberian Platform. It has been found that the trilobite assemblage from the Bergeroniellus ketemensis Zone (bottom of the Toyonian) is very much the same as that from the underlying Bergeroniaspis ornata Zone (terminal Botomian zone). It has been suggested to combine these zones into one with the index species Bergeroniaspis ornata. The greatest changes in the trilobite assemblages are observed at a higher stratigraphic level, at the bottom of the Lermontovia grandis Zone (second Toyonian zone). This suggests that the lower boundary of the Toyonian should be placed at the bottom of this zone. This new boundary shows substantial changes in the trilobite abundance and diversity and is well-pronounced, not only in the stratotype sections of the Lena River, but also elsewhere in the Siberian Platform (the northeast and northwest of the region, the Anabar area, and others).
The mixture distribution models for interoccurence times of earthquakes

Published: June 2011

Abstract
Risk analyses made in the area of seismic activity are going to be of great importance in determining the earthquake interoccurence times. Several statistical methods have been developed for this purpose. Recently, Exponential, Gamma and Weibull distributions are the frequently used methods in this regard. In this study, we investigate the interoccurence time statistics of earthquakes which occurred in the area coordinated 39º–42º N latitude and 30º–40º E longitude in the North Anatolian Fault Zone (NAFZ) between the years 1960–2008, with a mixture of two different distributions of Exponential, Gamma and Weibull and a mixture of the same kind of distribution. We found that the mixture distributions are more suitable than the other examined distribution models for small magnitudes (mc ≥ 3). Also Weibull-Gamma and Weibull-Exponential distributions are agreeable for large magnitudes (mc ≥ 5).
On the Observable Transition to Living Matter

Published: June 2011

Abstract
In recent developments in chemistry and genetic engineering, the humble researcher dealing with the origin of life finds her(him)self in a grey area of tackling something that even does not yet have a clear definition agreed upon. A series of chemical steps is described to be considered as the life–nonlife transition, if one adheres to the minimalistic definition: life is self-reproduction with variations. The fully artificial RNA system chosen for the exploration corresponds sequence-wise to the reconstructed initial triplet repeats, presumably corresponding to the earliest protein-coding molecules. The demonstrated occurrence of the mismatches (variations) in otherwise complementary syntheses (“self-reproduction”), in this RNA system, opens an experimental and conceptual perspective to explore the origin of life (and its definition), on the apparent edge of the origin.
