Published: July 2015

SummaryVertebrate pigmentation provides an ideal system for studying the intersections between evolution, genetics, and developmental biology. Teleost fish, with their accessible developmental stages and intense and diverse colours produced by chromatophores, are an ideal group for study. We set out to test whether Betta splendens is a good model organism for studying the evolution and development of diverse pigmentation. Our results demonstrate that B. splendens can be bred to produce large numbers of offspring with easily visualized pigment cells. Depending on the colour of the parents, there was variation in larval pigmentation patterns both within and between breeding events. In juveniles the developing adult pigmentation patterns showed even greater variation. These results suggest that B. splendens has great potential as a model organism for pigmentation studies.
Absence of connexin43 and connexin45 does not disturb pre- and peri-implantation development

Published: July 2015

SummaryGap junctional intercellular communication is assumed to play an important role during pre- and peri-implantation development. In this study, we eliminated connexin43 (Cx43) and connexin45 (Cx45), major gap junctional proteins in the pre- and peri-implantation embryo. We generatedCx43−/−Cx45−/−embryos byCx43+/−Cx45+/−intercrossing, because mice deficient inCx43(Cx43−/−) exhibit perinatal lethality and those deficient inCx45(Cx45−/−) exhibit early embryonic lethality. Wild-type,Cx43−/−,Cx45−/−, andCx43−/−Cx45−/−blastocysts all showed similar outgrowths inin vitroculture. Moreover,Cx43−/−Cx45−/−embryos were obtained at the expected Mendelian ratio up to embryonic day 9.5, when theCx45−/−mutation proved lethal. TheCx43−/−Cx45−/−embryos seemed to have no additional developmental abnormalities in comparison with the single knockout strains. Thus, pre- and peri-implantation development does not requireCx43andCx45.Other gap junctional proteins are expressed around these stages and these may compensate for the lack ofCx43andCx45.
Efficient Scheme for Perfect Collective Einstein-Podolsky-Rosen Steering
Authors: Wang M. , Gong Q. H. , Ficek Z. , He Q. Y. 
Published: July 2015

AbstractA practical scheme for the demonstration of perfect one-sided device-independent quantum secret sharing is proposed. The scheme involves a three-mode optomechanical system in which a pair of independent cavity modes is driven by short laser pulses and interact with a movable mirror. We demonstrate that by tuning the laser frequency to the blue (anti-Stokes) sideband of the average frequency of the cavity modes, the modes become mutually coherent and then may collectively steer the mirror mode to a perfect Einstein-Podolsky-Rosen state. The scheme is shown to be experimentally feasible, it is robust against the frequency difference between the modes, mechanical thermal noise and damping and coupling strengths of the cavity modes to the mirror.
Report on National Sociological Associations in Europe

Published: July 2015

ABSTRACT
As the official journal of the ESA, European Societies was asked to publish this report because of its special interest for the readers. This is a slightly shortened version of the first report on National Sociological Associations which was submitted to the European Sociological Association in November 2014. A series of relevant tables can be found on the ESA site: http://www.europeansociology.org/national-associations.html.ABSTRACT: This report presents the results of a survey on the National Associations of Sociology in Europe conducted in the years 2012–2013 by the European Sociological Association (ESA) under the auspices of its Committee for National Associations. The National Associations of Sociology were progressively established and institutionalized throughout the twentieth century, each one reflecting the political circumstances of the European Continent at the time. Of the 40 associations surveyed, 10% were in existence in 1950, which shows that the consolidation of the associative movement of sociologists in Europe is generally quite recent and gradually built up over the course of a century or more. The size of each association in terms of numbers of members is a key dimension in understanding how sociology is organized throughout Europe. The same may be said of the difficulties encountered when establishing the ESA as recently as 1992. The results of the survey show that the European sociological community is the aggregate of several parallel currents going back well over a hundred years. Each current has generated as many tributaries as there are individual academic and professional corporations operating in the dozens of countries where sociology has been able to take root and develop, whilst favoured – or sometimes opposed – by university and social policies, governments and public or private bodies. Moreover, each country has its own story to tell about the particular claims and losses, its ups and downs, advances and set-backs that sociology as a discipline has experienced.
Functional diversity appropriateness

Published: July 2015

Purpose– The purpose of this paper is to investigate how perceptions of team performance and teamwork processes relate to functional diversity appropriateness perceptions (FDAP), that is, whether one believes that the right functions are represented in a team. Thereby, the authors distinguish between perceptions of team managers and team members.Design/methodology/approach– The study involved a cross-sectional survey study among 48 sourcing teams from 12 multinational companies, all from different industries.Findings– Members’ and managers’ congruent perceptions of performance showed differential relationships with their perceptions of the team’s functional diversity appropriateness. For managers, perceptions of team performance and functional diversity appropriateness were directly and positively related. For team members, this relationship was moderated by teamwork behavior. Moreover, unlike team members, purchasing managers did not consider functionally diverse teams to be more suitable for executing sourcing tasks.Research limitations/implications– This study identified teamwork behavior as a critical element for explaining the differences in FDAP of members and managers of sourcing teams.Practical implications– Rather than homogenizing team structures, managers should stimulate good teamwork behavior that allows for an the integration of interests and insights from different functional areas.Originality/value– This study adds to functional diversity literature as well as perceptual distance literature by revealing how different team effectiveness criteria shape managers’ and members’ perceptions of functional diversity appropriateness.

Published: July 2015

AbstractSeveral studies have evaluated the associations between methylenetetrahydrofolate reductase (MTHFR) C677T and psoriasis. However, the results remain inconclusive. The objective of the present study was to conduct a qualitative and quantitative meta‐analysis investigating the associations between MTHFR C677T and psoriasis. A published work search of PubMed, Embase, Web of Science and Chinese National Knowledge Infrastructure database were conducted to identify all publications concerning MTHFR C677T polymorphism and psoriasis on 1 October 2014. The principal outcome measure for evaluating the strength of the association was crude odds ratios along with their corresponding 95% confidence intervals. Data were extracted and statistical analyses were implemented using STATA version 12.0 software. A total of 1179 psoriatic cases and 937 controls from five case–control studies concentrating on the association between MTHFR C677T polymorphism and psoriasis were included in this qualitative meta‐analysis. Pooled analysis revealed that there is no association between this polymorphism and susceptibility to psoriasis in dominant, recessive, allele and additive models under a random‐effect model. However, a marginal significant association was found in the overdominant model under fixed‐effect model. Subgroup analysis of ethnicity demonstrated that there is no association between MTHFR C677T polymorphism and either Asian or European psoriatic patients. In conclusion, MTHFR C677T polymorphism, qualitatively, is not a genetic factor for the pathogenesis of psoriasis but could quantitatively reflect the severity of psoriasis to some extent.

Published: July 2015

AbstractObjectivesThe purpose of this study was to describe the force generated by two different removal devices used to retrieve cemented crowns on implant abutments. The influence of six different operators was evaluated.Material and methodsThree replicated Coronaflex® (Kaltenbach & Voigt GmbH, KaVo Dental GmbH) and reverse hammer setups were tested. The experimental setup has employed a screw bearing a diametral hole through which a loop holder passed. The screw was attached to a force transducer (Brüel & Kjær, type 8201), and the loop holder arm was kept perpendicular to the transducer axis. The results were statistically evaluated with ANOVA.ResultsThe operator has resulted to play significant influence with reference to reverse hammer (coefficient of variation 43.3%) rather than with Coronaflex® (9.8%). Evaluating every single operator, more variation can still be found by considering each reverse hammer (37.5%) rather than each Coronaflex® (8.8%).ConclusionCoronaflex® device was found to systematically reach a more repeatable and higher peak amplitude of forces compared with reverse hammer, both by experienced and inexperienced operators.
Grüner Tee in der Dermatologie – Mythen und Fakten

Published: July 2015

ZusammenfassungDer Genuss von grünem Tee hat in asiatischen Ländern – vor allem in China – eine lange Tradition. Die epidemiologisch und experimentell beobachteten antikarzinogenen und antiinflammatorischen Effekte von grünem Tee haben zum Einsatz von Grüntee‐Extrakten bei verschiedenen therapeutischen Anwendungen geführt – sowohl in dermatologischen als auch in kosmetischen Präparaten, wobei die umfangreichsten Untersuchungen für die antikarzinogene und chemopräventive Wirkung von grünem Tee bzw. seines Hauptbestandteils Epigallocatechin‐3‐gallat vorliegen. Fast ebenso gut nachgewiesen ist die Wirkung bei Infektionskrankheiten wie kutanen Virusinfektionen. Zur topischen Behandlung von Genitalwarzen wurde eine Salbe mit Grüntee‐Extrakten 2010 in den USA und kürzlich auch in Europa zugelassen. Experimentelle Daten, die auf eine Blockade zentraler Signaltransduktionsfaktoren hinweisen, haben zur Untersuchung von Catechinen bei entzündlichen Erkrankungen wie atopischer Dermatitis geführt. Die Ansicht, grüner Tee sei eine „Wunderwaffe“ gegen Krankheiten, ist bereits Tausende von Jahren alt. Einer chinesischen Legende zufolge bemerkte der antike Kaiser Shen Nung ein herrliches Aroma, nachdem einige Blätter eines in der Nähe stehenden Baumes in kochendes Wasser gefallen waren. Sofort erklärte er das neue „Getränk“ zu einem „Geschenk des Himmels“, was den Ursprung der – bis heute bestehenden – Überzeugung bildete, grüner Tee sei ein Arzneimittel aus der Natur und gegen viele verschiedene Krankheiten wirksam. Dieser Übersichtsartikel fasst die biologischen und klinischen Effekte von grünem Tee zusammen.

ZusammenfassungHintergrund und ZielsetzungBotulinumtoxin Typ A ist eine wirksame, gut verträgliche, wenn auch temporäre Therapieoption gegen primäre axilläre Hyperhidrose. Über den Einfluss von wiederholten Injektionen auf die Wirkdauer ist jedoch wenig bekannt.Patienten und Methoden139 Patienten mit primärer axillärer Hyperhidrose wurden 50 Botulinumtoxin‐Einheiten je Axilla injiziert. Die Wirkdauer wurde bei 101 Patienten, die mindestens 3 Behandlungen erhalten hatten, nach der ersten, zweiten, und letzten Behandlung untersucht.ErgebnisseDie Wirkung hielt im Durchschnitt nach der ersten, zweiten, und letzten Injektion jeweils 4,0 Monate, 4,5 Monate, und 5,0 Monate an. Insgesamt war die Wirkdauer nach der letzten Injektion signifikant länger als nach der ersten Injektion (p = 0,0055, Wilcoxon‐Vorzeichen‐Rang‐Test). Ebenso gab es deutliche Unterschiede zwischen der ersten und der zweiten Injektion (p = 0,0302), sowie zwischen der zweiten und der letzten Injektion (p = 0,0381). Bei 25,7 % der Patienten blieb die Wirkdauer über die gesamte Behandlungszeit unverändert.SchlussfolgerungenWiederholte Botulinumtoxin‐Behandlungen führten zu einer signifikant verlängerten Wirkdauer bei axillärer Hyperhidrose. Während sich die durchschnittliche Wirkdauer mit jeder Behandlung weiter erhöhte, gab es dennoch erhebliche interindividuelle Unterschiede.

ABSTRACTBACKGROUND AND PURPOSESophisticated algorithms to infer disease diagnosis, pathology progression and patient outcome are increasingly being developed to analyze brain MRI data. They have been successfully implemented in a variety of diseases and are currently investigated in the field of neuropsychiatric disorders, including autism spectrum disorder (ASD). We aim to test the ability to predict ASD from subtle morphological changes in structural magnetic resonance imaging (sMRI).METHODSThe analysis of sMRI of a cohort of male ASD children and controls matched for age and nonverbal intelligence quotient (NVIQ) has been carried out with two widely used preprocessing software packages (SPM and Freesurfer) to extract brain morphometric information at different spatial scales. Then, support vector machines have been implemented to classify the brain features and to localize which brain regions contribute most to the ASD‐control separation.RESULTSThe features extracted from the gray matter subregions provide the best classification performance, reaching an area under the receiver operating characteristic curve (AUC) of 74%. This value is enhanced to 80% when considering only subjects with NVIQ over 70.CONCLUSIONSDespite the subtle impact of ASD on brain morphology and a limited cohort size, results from sMRI‐based classifiers suggest a consistent network of altered brain regions.
A Partial Palatal Coverage Overdenture Retained by Zygomatic Implants

Published: July 2015

AbstractProsthodontic rehabilitation of an atrophic edentulous maxilla can be challenging and is further complicated when multiple risk factors are present. Fixed prostheses require multiple implants for support/retention organized in biomechanically favorable positions in order to afford a good prognosis. Such suitable implant arrangements in an atrophic edentulous ridge can often be difficult to achieve. Removable prostheses require fewer implants for a favorable prognosis and can furthermore take advantage of the additional anatomical structures for support/retention. This clinical treatment will describe the fabrication of a partial palatal coverage overdenture retained by zygomatic implants.

AbstractPurposePeri‐implantitis is one of the most common inflammatory complications in dental implantology. Similar to periodontitis, in peri‐implantitis, destructive inflammatory changes take place in the tissues surrounding a dental implant. Bacterial flora at the failing implant sites resemble the pathogens in periodontal disease and consist of Gram‐negative anaerobic bacteria including Aggregatibacter actinomycetemcomitans (Aa). Here we demonstrate the effectiveness of a silver lactate (SL)‐containing RGD‐coupled alginate hydrogel scaffold as a promising stem cell delivery vehicle with antimicrobial properties.Materials and MethodsGingival mesenchymal stem cells (GMSCs) or human bone marrow mesenchymal stem cells (hBMMSCs) were encapsulated in SL‐loaded alginate hydrogel microspheres. Stem cell viability, proliferation, and osteo‐differentiation capacity were analyzed.ResultsOur results showed that SL exhibited antimicrobial properties against Aa in a dose‐dependent manner, with 0.50 mg/ml showing the greatest antimicrobial properties while still maintaining cell viability. At this concentration, SL‐containing alginate hydrogel was able to inhibit Aa growth on the surface of Ti discs and significantly reduce the bacterial load in Aa suspensions. Silver ions were effectively released from the SL‐loaded alginate microspheres for up to 2 weeks. Osteogenic differentiation of GMSCs and hBMMSCs encapsulated in the SL‐loaded alginate microspheres were confirmed by the intense mineral matrix deposition and high expression of osteogenesis‐related genes.ConclusionTaken together, our findings confirm that GMSCs encapsulated in RGD‐modified alginate hydrogel containing SL show promise for bone tissue engineering with antimicrobial properties against Aa bacteria in vitro.
The Use of a Modified Poly‐Ether‐Ether‐Ketone (PEEK) as an Alternative Framework Material for Removable Dental Prostheses. A Clinical Report
Authors: Zoidis Panagiotis , Papathanasiou Ioannis , Polyzois Gregory 
Published: July 2015

AbstractThis clinical report presents a modified poly‐ether‐ether‐ketone (PEEK) as an alternative material for the fabrication of distal extension removable dental prosthesis (RDP) frameworks. This material can be used for patients allergic to metals, or who dislike the metallic taste, the weight, and the unpleasant metal display of the denture framework and retentive clasps. This modified PEEK material, known as BioHPP, is a biocompatible, nonallergic, rigid material, with flexibility comparable to bone, high polishing and low absorption properties, low plaque affinity, and good wear resistance. It has been used for years in orthopedics and medical technology. BioHPP frameworks can be constructed either via CAD/CAM manufacturing or via the conventional lost wax technique. The clinical use of a BioHPP RDP framework is presented as an alternative for the treatment of a distal extension case.

ObjectivesTo investigate single or combined effect of silodosin, an α1A‐adrenoceptor antagonist, and imidafenacin, an antimuscarinic agent, on bladder function in a subacute bladder outlet obstruction (BOO) model of male rats.MethodsPartial BOO was created in male Wistar rats by ligating the urethra with a steel rod. On day 10 after surgery, when frequent voiding was most remarkable on voiding behavior measurement in a metabolic cage, cystometric investigations in a conscious restrained condition were conducted with cumulative intravenous administration of silodosin alone (0.1, 1, 10, and 100 µg/kg), imidafenacin alone (1, 3, and 10 µg/kg), or a combination of the two drugs.ResultsWhen compared with the Sham rats, the BOO rats showed an increase in bladder capacity, residual volume, mean amplitude and the number of non‐voiding contractions (NVCs), accompanied with an increase in bladder weight. In the BOO rats, silodosin alone at 100 µg/kg significantly decreased the number of NVCs, whereas imidafenacin alone at 3 and 10 µg/kg significantly decreased both the number and mean amplitude of NVCs. The combination administration with lower doses (silodosin at 10 µg/kg and imidafenacin at 1 µg/kg) significantly suppressed both the number and mean amplitude of NVCs.ConclusionsThe present results indicate a suppressive effect of silodosin or imidafenacin alone and a synergic effect of the combination of these two drugs on NVCs in a subacute BOO model of male rats.

Published: July 2015

SummaryColonisation of the gastrointestinal tract is influenced by primary microbial exposure and bioactive factors in breastmilk. The aim was to explore the prevalence of oral Candida in the first year of life in relation to selected exposures. Oral Candida was studied in 100 healthy infants at 4 and 8 weeks, 3, 6 and 12 months of age and related to delivery mode, birth weight, infant health and feeding, antibiotics, antimycotics, steroids and probiotics in mother and infant, living conditions, maternal smoking and infections The association between lactoferrin and antisecretory factor in breastmilk and maternal serum haemoglobin, transferrin, and ferritin levels in relation to oral Candida was also explored. About 11% to 15% of the infants had oral Candida at the respective age. Colonisation was fairly stable until 6 months of age. There was no conclusive impact of the investigated exposures at entry. Infants with a furry pet at home had a lower frequency of Candida at 3 months, (P < 0.05) whereas all but one colonised infant had older siblings at 12 months (P < 0.01). Lactoferrin in breastmilk was negatively associated with colonisation at 6 months of age. It is concluded that 11 to 15% had oral Candida. Exposure to furry pets and siblings impacted oral Candida.
The Benefits of Dominance Complementarity in Negotiations
Authors: Wiltermuth Scott , Tiedens Larissa Z. , Neale Margaret 
Published: July 2015

AbstractWe investigated whether dominance complementarity can lead people to reach mutually beneficial outcomes in negotiations by increasing the likelihood that they will successfully coordinate the exchange of information. We suggest that negotiators who differ in how dominantly they behave in the negotiation exchange information effectively because they fulfill different roles in the negotiation process. Study 1 demonstrated that dominant negotiators generally assert their desires, while relatively submissive negotiators generally ask questions to find ways to satisfy their own desires without escalating conflict with the dominant negotiators. Studies 2 and 3 demonstrated that participants were best able to discover integrative agreements when one negotiator was instructed to behave dominantly and the other negotiator, submissively. Improved information exchange mediated the relationship between dominance complementarity and improved joint outcomes in Study 3.
