Published: December 2012

Purpose Incident arteriovenous fistula (AVF) rates remain low. AVF placement is often not attempted because of small cephalic vein (CV) diameter. We postulated that isometric handgrip exercises would increase forearm CV diameter and allow successful AVF creation in non-AVF candidates. Methods Adult subjects without prior vascular access (eGFR<25mL/min/1.73m2; CV<2.5mm) were prospectively enrolled. They performed daily handgrip exercises in the preferred access arm (EA), with the nonexercised arm (NEA) as control. Adherence was assessed by exercise logs and grip strength. CV diameter was measured at baseline, four and eight weeks by ultrasound. The primary endpoint was the mean increase in CV diameter. Secondary endpoints were mean CV diameter increase from baseline, increased proportion of potential AVF sites and successful AVF placement. Results A total of 17 subjects were enrolled and 15 completed the study. EA grip strength increased significantly. Mean CV diameter increased in both the EA and NEA by 0.48-0.59 and 0.71-0.81 mm (P=NS), respectively. Compared to baseline, all CV diameters increased significantly (P<.05) after four weeks. In the EA, mean distal and proximal CV increased from 1.66 to 2.13 mm and from 2.22 to 2.81 mm, respectively. Similar changes were noted in the NEA. There were also significant increases in the number of sites and subjects eligible for AVF creation. Five subjects had successful AVF placement. Conclusions Isometric handgrip exercises resulted in significant CV diameter increases after four weeks, in both the EA and the NEA and potentially allows for AVF creation in those not previously deemed candidates.
Digoxigenin-Labeled Probe-Based Colony Blotting Assay for Rapid Quantification of Salmonella Serovars in Seafood and Water
Authors: Kumar Rakesh , Lalitha K V 
Published: December 2012

Abstract
A non-radio-labeled probe-based detection method was developed for rapid enumeration of Salmonella in seafood and water samples. A Salmonella-specific invA gene probe was developed using a digoxigenin-based non-radio labeling assay, which was evaluated with naturally contaminated seafood and water samples. The probe-based technique was further compared with the quantitative PCR assay. The method was specific for detection of different Salmonella serovars without any nonspecific hybridization with other Salmonella-related Enterobacteriaceae. The optimum labeling efficiency was determined for the labeled probe, and 10 pg/μL probe concentration was observed to be most efficient for detection of Salmonella colonies on nylon membrane. Quantification of Salmonella in naturally contaminated seafood and water samples (n = 21) was in the range 10–102 CFU/mL. The assay successfully quantified Salmonella in spiked seafood and water samples in the presence of background flora, and the entire assay was completed within 48 h. The probe-based assay was further evaluated with real-time PCR, and results showed that the assay was comparable to real-time PCR assay. Thus, this probe-based assay can be a rapid, useful, and alternative technique for quantitative detection of Salmonella in food, feed, and water samples.

Published: December 2012

Abstract
Triazole-derivative metabolites can occur in plant and animal materials and in water. Due to their physical-chemical properties, their analysis in complex matrixes is very difficult. The objective of this work was to develop a method for the analysis of these analytes that is easy to handle, quick, and enables quantification at a residue level of 0.01 mg/kg. Using the LC-differential mobility spectrometry/MS/MS system, cleanup and derivatization processes became unnecessary. For more than 10 representative plant materials it could be shown that the new method is valid and reproducible, thus leading to accurate and reliable results.

Abstract
The accuracy, repeatability, and reproducibility characteristics of a method using immunoaffinity column (IAC) cleanup with postcolumn derivatization and LC with a fluorescence detector (FLD) for determination of aflatoxins (AFs; sum of AFs B1, B2, G1, and G2) in olive oil, peanut oil, and sesame oil have been established in a collaborative study involving 15 laboratories from six countries. Blind duplicate samples of blank, spiked at levels ranging from 0.25 to 20.0 μg/kg for AF, were analyzed. A naturally contaminated peanut oil sample was also included. Test samples were extracted with methanol–water (55 + 45, v/v). After shaking and centrifuging, the lower layer was filtered, diluted with water, and filtered through glass microfiber filter paper. The filtrate was then passed through an IAC, and the toxins were eluted with methanol. The toxins were then subjected to RPLC-FLD analysis after postcolumn derivatization. Average recoveries of AFs from olive oil, peanut oil, and sesame oil ranged from 84 to 92% (at spiking levels ranging from 2.0 to 20.0 μg/kg); of AFB1 from 86 to 93% (at spiking levels ranging from 1.0 to 10.0 μg/kg); of AFB2 from 89 to 95% (at spiking levels ranging from 0.25 to 2.5 μg/kg); of AFG1 from 85 to 97% (at spiking levels ranging from 0.5 to 5.0 μg/kg); and of AFG2 from 76 to 85% (at spiking levels ranging from 0.25 to 2.5 μg/kg). RSDs for within-laboratory repeatability (RSDr) ranged from 3.4 to 10.2% for AF, from 3.5 to 10.9% for AFB1, from 3.2 to 9.5% for AFB2, from 6.5 to 14.9% for AFG1, and from 4.8 to 14.2% for AFG2. RSDs for between-laboratory reproducibility (RSDR) ranged from 6.1 to 14.5% for AF, from 7.5 to 15.4% for AFB1, from 7.1 to 14.6% for AFB2, from 10.8 to 18.1% for AFG1, and from 7.6 to 23.7% for AFG2. Horwitz ratio values were ≤2 for the analytes in the three matrixes.
Validation of the Delvotest® SP NT
Authors: Hennart Stephen L A , Faragher John 
Published: December 2012

Abstract
Delvotest® SP NT is designed to test milk for the presence of antibacterial substances such as antibiotics. The test is made of an agar gel containing bacterial spores and a pH indicator. The milk sample is added onto the agar gel, and the test is placed for incubation at 64°C. The principle of the test is based on the diffusion of possible inhibitory substances that may be present in the milk sample into the agar. This reduces growth and acid production by the test organism and delays or prevents the agar from changing color from purple to yellow. The present report includes all technical details about the Delvotest SP NT and the results of the validation study. The validation study demonstrates that the Delvotest SP NT conforms to the product performance claims and confirms the robustness of the test. The Delvotest SP NT is therefore granted Performance Tested MethodSM certification.

Published: December 2012

Abstract
A method was developed for microplate-based oxygen radicals absorbance capacity (ORAC) using pyrogallol red (PGR) as probe (ORAC-PGR). The method was evaluated for linearity, precision, and accuracy. In addition, the antioxidant capacity of commercial beverages, such as wines, fruit juices, and iced teas, was measured. Linearity of the area under the curve (AUC) versus Trolox® concentration plots was [AUC = (845 ± 110) + (23 ± 2) [Trolox, μM]; R = 0.9961, n = 19]. Analyses showed better precision and accuracy at the highest Trolox concentration (40 μM) with RSD and recovery (REC) values of 1.7 and 101.0%, respectively. The method also showed good linearity for red wine [AUC = (787 ± 77) + (690 ± 60) [red wine, μL/mL]; R = 0.9926, n = 17], precision and accuracy with RSD values from 1.4 to 8.3%, and REC values that ranged from 89.7 to 103.8%. Red wines showed higher ORAC-PGR values than white wines, while the ORAC-PGR index of fruit juices and iced teas presented a wide range of results, from 0.6 to 21.6 mM of Trolox equivalents. Product-to-product variability was also observed for juices of the same fruit, showing the differences between brands on the ORAC-PGR index.

Published: December 2012

The Internet Public Library (IPL), now known as ipl2, was created in 1995 with the mission of serving the public by providing librarian-recommended Internet resources and reference help. We present an exploratory case study on public perceptions of an “Internet public library,” based on qualitative analysis of interviews with ten college student participants: some current users and others unfamiliar with the IPL. The exploratory interviews revealed some confusion around the IPL’s name and the types of resources and services that would be offered. Participants made many positive comments about the IPL’s resource quality, credibility, and personal help.
Semantic Web for Reliable Citation Analysis in Scholarly Publishing
Authors: Tous Ruben , Guerrero Manel , Delgado Jaime 
Published: December 2012

Analysis of the impact of scholarly artifacts is constrained by current unreliable practices in cross-referencing, citation discovering, and citation indexing and analysis, which have not kept pace with the technological advances that are occurring in several areas like knowledge management and security. Because citation analysis has become the primary component in scholarly impact factor calculation, and considering the relevance of this metric within both the scholarly publishing value chain and (especially important) the professional curriculum evaluation of scholarly professionals, we defend that current practices need to be revised. This paper describes a reference architecture that aims to provide openness and reliability to the citation-tracking lifecycle. The solution relies on the use of digitally signed semantic metadata in the different stages of the scholarly publishing workflow in such a manner that authors, publishers, repositories, and citation-analysis systems will have access to independent reliable evidences that are resistant to forgery, impersonation, and repudiation. As far as we know, this is the first paper to combine Semantic Web technologies and public-key cryptography to achieve reliable citation analysis in scholarly publishing
Usability of the VuFind Next-Generation Online Catalog
Authors: Emanuel Jennifer 
Published: December 2012

The VuFind open–source, next-generation catalog system was implemented by the Consortium of Academic and Research Libraries in Illinois as an alternative to the WebVoyage OPAC system. The University of Illinois at Urbana-Champaign began offering VuFind alongside WebVoyage in 2009 as an experiment in next generation catalogs. Using a faceted search discovery interface, it offered numerous improvements to the UIUC catalog and focused on limiting results after searching rather than limiting searches up front. Library users have praised VuFind for its Web 2.0 feel and features. However, there are issues, particularly with catalog data.
Label de calidad e indicaciones geográficas protegidas como estrategia empresarial: El caso Brandy de Jerez desde una perspectiva de las RR.PP
Authors: Pulido Marta , Jiménez Gloria , Silva Carmen 
Published: December 2012

La Indicación Geográfica Protegida (IGP), como label de calidad, supone una doble perspectiva: un valor añadido a la marca del producto, al tiempo que es una garantía de calidad mínima. Sirve para hacer alusión a productos de la industria agroalimentaria que se identifican por unas características diferentes y propias que se derivan de su procedencia geográfica, añadiendo percepción pública del mismo, controles y normativas estrictas de elaboración y un marco legal específico. En este sentido, las indicaciones geográficas protegidas juegan un importante papel en la gestión empresarial y, desde una óptica comunicacional, un rol fundamental en la gestión de las RR.PP. En este estudio realizamos un estudio del Consejo Regulador de la indicación geográfica protegida Brandy de Jerez a través del estudio de caso combinado con otras técnicas de investigación como son la entrevista, la observación directa y la consulta de fuentes de datos secundarios. Consideramos, pues, a partir de las veinte memorias anuales que el Consejo Regulador de la indicación geográfica protegida Brandy de Jerez emitió desde 1989 hasta 2008, la relación existente entre el label de calidad IGP y la gestión de las RR.PP. de las empresas y productos que quedan bajo el amparo esta protección.

AbstractObjectiveIn the K/BxN mouse model of inflammatory arthritis, T cells carrying a transgenic T cell receptor initiate disease by helping B cells to produce arthritogenic anti–glucose‐6‐phosphate isomerase (anti‐GPI) autoantibodies. We found that lethally‐ irradiated lymphocyte‐deficient C57BL/6 (B6).g7 (I‐Ag7+) recombinase‐activating gene–deficient (Rag−/−) mice reconstituted with K/BxN hematopoietic stem and progenitor cells exhibit arthritis by week 4. In contrast, healthy B6.g7 recipients of K/BxN hematopoietic stem and progenitor cells show only mild arthritis, with limited extent and duration. The objective of this study was to investigate the factors responsible for the attenuation of arthritis in B6.g7 recipients.MethodsAntibody responses were measured by enzyme‐linked immunosorbent assay. Fluorescence‐activated cell sorting analyses were performed for testing chimerism, expression of markers of activation and suppression, tetramer binding, and intracellular cytokines in CD4+ T cells. Suppressive activity of CD4+ T cells was studied by adoptive transfer.ResultsTiters of anti‐GPI antibodies in reconstituted B6.g7 mice were ∼60‐fold lower than in reconstituted B6.g7 Rag−/−mice. Examination of chimerism in the reconstituted B6.g7 mice showed that B cells and myeloid cells in these mice were donor derived, but CD4+ T cells were primarily host derived and enriched for cells expressing the conventional regulatory markers CD25 and FoxP3. Notably, CD4+CD25−FoxP3− T cells expressed markers of suppressive function (CD73 and folate receptor 4), and delayed disease after adoptive transfer. Activation of donor‐derived CD4+ T cells was reduced, and thymic deletion of these cells appeared increased.ConclusionDespite myeloablation, host CD4+ T cells having a regulatory phenotype emerge in these mice and attenuate autoimmunity.

Published: December 2012

AbstractObjectiveTo investigate whether a human X chromosome locus of IRAK1 and MECP2 is associated with susceptibility to rheumatoid arthritis (RA), an autoimmune disease that predominantly affects women.MethodsA total of 2,334 unrelated Korean participants (including 1,318 patients with RA) were genotyped for 5 tag single‐nucleotide polymorphisms (SNPs) and 3 additional SNPs in an Xq28 region harboring MECP2 and IRAK1. Twenty‐nine additional neighboring SNPs were imputed using the Korean HapMap Project data. All 37 SNPs were statistically tested for association with RA susceptibility, and 2 SNPs associated with RA were examined for their functional effects.ResultsRA susceptibility was associated with multiple SNPs in a 79‐kb linkage disequilibrium block harboring both MECP2 and IRAK1. The most significant association was for MECP2 SNP rs1734792 (P = 0.00089), but 2 nonsynonymous IRAK1 SNPs, rs1059702 (P = 0.0034) and rs1059703 (P = 0.0042), which were in strong linkage disequilibrium with the MECP2 SNP (D′ = 0.87 and 0.91, respectively) affected IRAK1 protein activity. The major haplotype of the 2 nonsynonymous SNPs was associated with a 1.7‐fold increase in RA susceptibility versus the minor haplotype (P = 0.0082), and with increased IRAK1 activity, which was demonstrated by a 1.7‐fold increase in the intracellular activity of transcription factor NF‐κB.ConclusionOur findings indicate that RA susceptibility is associated with multiple SNPs in MECP2 and IRAK1, but high linkage disequilibrium between them does not allow for further localization. Therefore, both genes remain candidates. Nevertheless, the major haplotype of the 2 nonsynonymous IRAK1 SNPs encoding for pPhe196Ser and pSer532Leu confers enhanced IRAK1 activity and, consequently, enhanced susceptibility to RA, as compared to the minor haplotype.
Commitment Strategies for Sustainability: How Business Firms Can Transform Trade‐Offs Into Win–Win Outcomes
Authors: Beckmann Markus , Hielscher Stefan , Pies Ingo 
Published: December 2012

ABSTRACTThis paper addresses a fundamental problem in corporate sustainability: How can corporations transform trade‐offs through win–win‐oriented governance strategies aimed at creating value? Drawing on new strands of research in business ethics, we employ an ‘ordonomic’ perspective and proceed in four steps. First, we sketch how sustainability semantics has evolved historically from a societal searchlight to a heuristics for business practice. Second, we discuss how business firms can make strategic use of moral commitments as governance contributions by deploying individual or collective self‐commitments as well as commitment services in their stakeholder relations. Third, we combine these four governance strategies with the three ESG (‘ecological, social and governance’) criteria of sustainability. We derive and illustrate with real‐life examples a 12‐box matrix as a tool for the strategic management of corporate sustainability. Fourth, we discuss the specific contribution of our ordonomic approach to the literature. Copyright © 2012 John Wiley & Sons, Ltd and ERP Environment

Published: December 2012

ABSTRACTThe resolution of seven enantiomeric pairs of chiral derivatives of xanthones (CDXs) on (S,S)‐Whelk‐O1 and l‐phenylglycine chiral stationary phases (CSPs) was systematically investigated using multimodal elution conditions (normal‐phase, polar‐organic, and reversed‐phase). The (S,S)‐Whelk‐O1 CSP, under polar‐organic conditions, demonstrated a very good power of resolution for the CDXs possessing an aromatic moiety linked to the stereogenic center with separation factor and resolution factor ranging from 1.91 to 7.55 and from 6.71 to 24.16, respectively. The chiral recognition mechanisms were also investigated for (S,S)‐Whelk‐O1 CSP by molecular docking technique. Data regarding the CSP–CDX molecular conformations and interactions were retrieved. These results were in accordance with the experimental chromatographic parameters regarding enantioselectivity and enantiomer elution order. The results of the present study fulfilled the initial objectives of enantioselective studies of CDXs and elucidation of intermolecular CSP–CDX interactions.
