Minimally invasive approach for small ventrally located intradural lesions of the craniovertebral junction
Authors: Eicker Sven O. , Mende Klaus Christian , Dührsen Lasse , Schmidt Nils Ole
Published: April 2015

OBJECT

The surgical management of lesions ventral to the neuraxis at the level of the craniovertebral junction (CVJ) and upper cervical spine is challenging. Here, the authors describe a minimally invasive dorsal approach for small ventrally located intradural lesions at the CVJ as an alternative for the more extensive classic transoral approach or variants of suboccipital approaches.

METHODS

Between 2012 and 2014, 6 symptomatic patients with a small lesion of the ventral aspect at the CVJ level were treated using a minimally invasive dorsal approach at the University Medical Center in Hamburg-Eppendorf, Germany. The anatomical distance between the posterior atlantooccipital membrane and the posterior atlantoaxial ligament, as determined by CT images, was assessed in the treated patients and in 100 untreated persons.

RESULTS

The authors treated 6 patients (mean age 54.7 years) who had a clinical presentation of mild neurological symptoms that disappeared after resection. Minimally invasive surgical dorsal access was achieved by using tubular systems and using the natural space between the occiput (C-0) and C-1, and in 1 case between C-1 and C-2, without having to remove bony structures. The postoperative course in each of the 6 patients was uneventful. The neuropatho-logical findings confirmed a meningotheliomatous meningioma (WHO Grade I) in 5 cases and an extramedullary cavernous hemangioma in 1 case. MRI confirmed complete resection of all the lesions. The atlantooccipital distances ranged from 3 to 17 mm (mean 8.98 mm) in the supine neutral position, and the atlantoaxial distances ranged from 5 to 17 mm (mean 10.56 mm). There were no significant differences between women and men (atlantooccipital p = 0.14; atlantoaxial p = 0.72).

CONCLUSIONS

The results of this study demonstrate that the minimally invasive dorsal approach using the space between C-0 and C-1 or C-1 and C-2 provides direct and sufficient exposure for the safe surgical resection of small ventrally located intradural lesions at the CVJ level while reducing the necessity for musculoskeletal preparation to a minimum.

Application of marker assisted selection for livestock improvement in Bangladesh
Authors: Moniruzzaman M , Khatun R , Mintoo AA
Published: April 2015

Molecular markers usually do not have any biological effect. They are identifiable DNA sequences, found at specific locations of the genome, and transmitted from one generation to the next. Marker assisted selection (MAS) is a novel technique that can complement traditional breeding methods for rapid genetic gains. Genetic gain through selective breeding is the objective of a breeder to achieve long term improvement in animal and plant genomes; however the pace of improvement is inversely proportional to the Generation Interval. Genetic improvement in livestock, particularly those with long generation intervals, requires decades for tangible results. Successful MAS breeding programmes require gene mapping, marker genotyping, quantitative trait loci (QTL) detection, genetic evaluation and finally MAS. Genomic selection is a form of markerassisted selection. Using markers covering the whole genome could mean potentially that all the genetic variance is explained; and the markers are assumed to be in linkage disequilibrium with the QTL so that the number of effects per QTL to be estimated is small. MAS drastically reduces generation interval and increases selection accuracy. Therefore, a breeding strategy based upon markers making the best use of the two approaches can facilitate rapid genetic gain though selection of markers related to economic traits such as milk and meat production. This review is designed to elaborate the technique of MAS and its application in developing countries. DOI: http://dx.doi.org/10.3329/bvet.v31i1.22837 Bangl. vet. 2014. Vol. 31, No. 1, 1-11

Published: April 2015

This study was undertaken to investigate the bacterial contamination of spicy puffed rice (Jhalmuri) sold by the street vendors at Bangladesh Agricultural University (BAU) campus. Fifteen spicy puffed rice samples were collected from street vendors at the Botanical Garden, Library premises, Riverside, Krishi Bishhobiddaloy (KB) High School and Veterinary Teaching Hospital compound at BAU campus. Microbial quality was assessed by total viable count (TVC), total coliform count (TCC) and total staphylococcal count (TSC). Samples were inoculated into selective media Eosin Methylene Blue (EMB) agar, Salmonella Shigella (SS) agar, Thiosulphate Citrate Bile Salts Sucrose (TCBS) agar and Mannitol Salt (MS) agar. E. coli and Staphylococcus spp. were identified from the samples. The TVC in spicy puffed rice sample ranged from log 4.5 cfu/g to log 5.4 cfu/g, TSC ranged from log 4.4 cfu/g to log 5.2 cfu/g and TCC ranged from log 1.4 cfu/g to log 4.3 cfu/g. Antibiotic sensitivity test showed that the isolates were sensitive to ciprofloxacin and gentamicin. E. coli were resistant to ampicillin, chloramphenicol and cephalexin and Staphylococcus spp. were resistant to ampicillin, cephalexin and vancomycin. Spicy puffed rice sold by the street vendors at BAU campus harboured multidrug resistant food borne bacteria which may cause public health hazard.

New information on Indian rhinoceroses (Rhinoceros unicornis) in Britain in the mid-eighteenth century
Authors: Grigson Caroline
Published: April 2015

Three Indian rhinoceroses (Rhinoceros unicornis) were present in Britain in the mid-eighteenth century. The first, a female, arrived in 1737, the second, a male, arrived in 1739, the third, a female known as Douwe Mout's rhinoceros or Clara, was shown in London, probably in 1756. Recent research in British newspapers provides new information about all three animals, and produces evidence to show that the rhinoceros exhibited in London in 1751–1752 was not Clara, but the female which had arrived in 1737.
The identity of Richard of Richard's pipit (Anthus richardi Vieillot, 1818)
Authors: Mearns Richard , Gouraud Christophe , Chevrier Laurent
Published: April 2015

Richard's pipit (Anthus richardi) is an annual vagrant to Europe from its eastern Palaearctic breeding grounds. It was first described in 1818 by Louis Vieillot from specimens obtained in eastern France and named for Richard de Lunéville. Although Richard was then a fairly well known natural history collector his identity became lost to succeeding generations of naturalists. He is identified here as Charles Richard (1745–1835), the director of the postal service at Lunéville. Some of his bird specimens still survive amongst the Baillon Collection at La Châtre but other birds, including the three syntypes of Richard's pipit, have not been traced.
The perfect pest: natural history and the red squirrel in nineteenth-century Scotland (William T. Stearn Prize 2014)
Authors: Holmes Matthew
Published: April 2015

Following the extirpation of the red squirrel from much of Scotland by the end of the eighteenth century, nineteenth-century naturalists strived to find evidence of its native Scottish status. As medieval accounts and Gaelic place names proved ambiguous, the true extent of the squirrel's former habitat was a matter of some debate. While numerous reintroductions of the species were made from the late eighteenth century, general enthusiasm for the return of the squirrel quickly turned to dismay, ultimately followed by persecution. If the squirrel originally represented a symbolic mission to rediscover a lost species, the physical animal itself fell below expectations. It became publically perceived as both economically and ecologically destructive. The squirrel was despised by foresters and landowners for damaging trees, while naturalists condemned the species for the destruction of bird's eggs and nests. This article will investigate naturalists' quests to rediscover the red squirrel, before examining changing attitudes to the species upon its reintroduction and gradual proliferation. The narrative will emerge through the works and correspondence of Scottish naturalist John Alexander Harvie-Brown (1844–1916) and The new statistical account of Scotland (1834–1845). The argument will be made that the red squirrel as an object of antiquarian curiosity initially made the species endearing to natural historians, as part of a wider fascination with extinct British fauna. However, the clash between naturalists’ established ornithological interests did little to endear the species to that community, leaving the red squirrel open to a policy of general persecution on economic grounds.
Józef Rostafiński's ethnobotanical enquiry of 1883 concerning Polish vernacular names and uses of plants
Authors: Köhler Piotr
Published: April 2015

In 1883, Polish botanist Józef Rostafiński distributed a questionnaire to Poles with knowledge of peasant culture. Rostafiński asked about the names and uses of about 130 various plants, both wild and cultivated. About 370 individuals took part in the survey, sending nearly 860 letters. Only 359, sent by 227 correspondents, are now stored at the Museum of the Jagiellonian University Botanical Garden (Kraków, Poland). These letters contain nearly 25,800 records. Despite obtaining a vast amount of information from his enquiry, Rostafiński never made full use of the data. Rostafiński's questionnaire occupies quite an early position in the history of ethnobotany. It was the most significant one at that time in regard of its size, issues included in the questions and the obtained results.
Touch and Go Records and the Rise of Hardcore Punk in Late Twentieth-Century Detroit
Authors: Carriere Michael H.
Published: April 2015

This essay uses the history of Touch and Go Records – an independent record label founded in 1981 – to show how the late twentieth-century environment of Detroit became fertile ground for the rise of hardcore punk. As the landscape of the post-industrial city was transformed by such developments as deindustrialization and white flight, a cadre of white, suburban youth transformed spaces of abandonment into places of innovation and alternative urban redevelopment, particularly in the city's troubled Cass Corridor neighborhood. Such urban spaces provided the room for musical experimentation in ways that were not possible in the postwar American suburb. Such a process was undoubtedly informed by the economic and political histories of post-industrial Detroit. Yet this essay argues that the rise of hardcore punk was more than an indicator of economic and political transformation; it was also a moment of cultural rupture. Viewed from such a perspective, one sees a group of musicians, writers, and others set on creating a new, viable art form, one that sought to critique and replace an older dominant musical culture that had come to be perceived as lacking vitality and originality. This moment of cultural realignment came to play a great role in the evolution of late twentieth century American culture.
History is What Hurts: Queer Feelings, Alien Temporalities in the Work of Gloria Anzaldúa
Authors: Hedrick Tace
Published: April 2015

The Chicana lesbian writer Gloria Anzaldúa believed that indigenous spirituality could be carried in the mixed-race ‘blood’ of the mestiza, and tapped into psychically. This psychic access could then bring up, as if from the depths of time, an authentically indigenous, if alien, soul-sensibility into the mestiza consciousness and thus into the present. Following Suzanne Bost, I think of this process as a way of ‘feeling pre-Columbian’. I argue that Anzaldúa used this feeling to queer the notion of historical change through a long and inaccessible time as, instead, a spatial and therefore crossable distance. In this paper, I trace a genealogy of what might loosely be called ‘New Age’ transnational Latin/o American notions that the indigenous psyche occupied a different (and more spiritual) temporality as groundwork in understanding how Anzaldúa comes to her complex envisioning of a bodily and psychic, queerly indigenous space outside popularly received ideas of historical time and cultural change. This intellectual genealogy illuminates how Anzaldúa comes to this rejection of ‘history’ as such, and to her formulation of an intimately alien, foldable psychic space outside time and historical change.

Types d'ambiance climatique : approche du gisement énergétique régional (Types of climatic atmosphere in Brittany)
Authors: Perron Gilles
Published: April 2015

Abstract. - In the western regions of France, the space-time definition of potential energy, for applications to bioclimatic habitat and solar energy systems, lies on a classification of climatic atmospheres in type-days. It includes the various elements of the atmospheric circulation at synoptic level and meteorological datas at ground level. Frequency study of type-days on the period 1951-1980 allows to estimate the potential energy. This research is completed by a sequential analysis describing the dynamic of atmospheric circulation as well as its effects on local climatic atmospheres.
Auch, Nîmes, Vaison-la-Romaine : retours d'expériences (Auch, Nîmes, Vaison-la-Romaine : lessons from experiences)
Authors: Garry Gérald
Published: April 2015

Abstract. - The floods which happened in the seventies and eighties and the regular increase of damages encouraged the French government to install an efficient policy of natural hazard prevention in 1982. It gave the definition of a methodology of very elaborate studies that was especially adapted to floods in plains, the most frequent at that time. But, paradoxically, the most important events that we have known for about 15 years, at Auch, at the Grand-Bornand, at Nimes and at Vaison-la-Romaine have been the result of different hydrological phenomena (urban run-off ; torrential floods). They contributed to progressively complete the legislative and regulation rules which to day should lead to the passage of the Projects of Hazard Prevention (P.P.R. in French) and to develop the knowledge of natural phenomena in a more global and pluridisciplinary approach.
Vers une approche globale de la sécurité en milieu urbain. Le point de vue de l'ingénieur (Toward a total security management in cities. The civil engineer point of view)
Authors: Deschanels Jean-Louis , Rouhet Jean-Claude
Published: April 2015

Abstract. - Security and safety improvements are usually related to catastrophic events. Thus for a long time, researches have been focused on causalities more than on consequences. Recent evolution in industrial systems security management has given way to new methods for consequences control, irrespective of causes. Application of this total analysis seems to be much fruitful in the case of complex systems such as firm or city. It is based on risk matrix techniques, and provides an appropriate tool for decision-making in risk management.

La réponse des acteurs basques aux défis du tourisme de demain : un management novateur et une marque territoriale
Authors: Férérol Marie-Ève
Published: April 2015

Au Pays Basque français, le secteur du tourisme représente une source d’emplois notable : 8 292 en 2011, soit 6 % des emplois totaux. Cependant, et malgré la bonne santé que l’activité peut afficher (+ 10 % de chiffre d’affaires en cinq ans), le tourisme basque présente certains handicaps, très ennuyeux dans un contexte de concurrence accrue entre destinations et face à des consommateurs de plus en plus versatiles. Pour répondre aux défis actuels et surtout aux défis du tourisme de demain, le Pays Basque français puise dans ses traditions pour initier une nouvelle dynamique. «  L’une des modalités du passage du temps réside, pour un lieu touristique donné, dans le changement de son propre système local d ’ acteurs, de pratiques, de normes, de valeurs, etc.  » (Equipe MIT, 2001, p. 271). La dynamique basque s’inscrit dans le développement soutenable du territoire et se traduit d’une part par la clustérisation des acteurs du tourisme (fait encore rare en France, cf. les écrits de Nathalie Fabry, 2009 et 2012) et d’autre part par la création d’une marque territoriale. Quels ont été les principes fondateurs de ces deux projets et en quoi peut-on les rapprocher des valeurs du développement durable ? Quels bénéfices en matière de développement local les acteurs en attendent-ils ? Telles sont les questions auxquelles notre article tentera de répondre.
Réforme liturgique et unité ecclésiale : l’expérience de Common Worship dans l’Église d’Angleterre
Authors: Tinteroff Natacha-Ingrid
Published: April 2015

Contrairement aux idées parfois communément admises sur le continent européen, l’histoire liturgique de l’église d’Angleterre ne s’est pas déroulée sans heurts. Depuis la Réforme, l’unité de la Church of England a été forgée par la tradition de la prière commune telle qu’elle fut exprimée dans le Book of Common Prayer de 1662. L’inadaptation des liturgies de cet ouvrage au contexte du xx e  siècle a nécessité une réforme liturgique majeure concrétisée en 2000 sous le nom de Common Worship . Si cette évolution a été contestée comme mettant à mort la conception classique de la prière commune, il s’avère que la réforme opérée a permis de restaurer une unité ecclésiale en perdition.
Le burn-out : une maladie du don ?
Authors: Ide Pascal
Published: April 2015

Le burn-out (BO) touche aujourd’hui un pourcentage impressionnant de la population active en Occident et bon nombre de prêtres, religieux et agents pastoraux. Après avoir brossé une brève histoire de sa découverte, puis l’avoir décrit (syndrome regroupant l’épuisement émotionnel, la dépersonnalisation et la réduction de l’accomplissement personnel), ce premier article propose une grille de lecture inédite pour expliquer autant l’origine que la nature du BO : dans le contexte d’une société du trop-plein, il serait une pathologie du don de soi. Pour le montrer, il élabore un modèle de l’amour-don rythmé en trois temps : la réception, l’appropriation et la donation. Un second article l’appliquera à la pastorale des prêtres qui, pour être l’un des secteurs le plus concernés, est encore souvent l’un des plus oubliés.
Against Manichaeism : The Politics of Forms of Life and the Possibilities of Critique
Authors: Celikates Robin
Published: April 2015

Les formes de vie sont souvent entendues comme étant « données », et donc protégées de la critique et de la réflexivité. Dans cet article, l’auteur montre d’abord pourquoi cette approche problématique vient d’une lecture partiale de Wittgenstein, puis montre que cette même approche nourrit la conception de la sociologie critique de Bourdieu. En s’appuyant sur une sociologie pragmatique de la critique, l’auteur s’oppose à de telles conceptions « manichéennes » qui opposent l’« intérieur », caractérisée par l’immersion non-réflexive, et l’« extérieur », lieu de la perspective de l’observateur-théoricien. Il insiste au contraire sur le caractère fondamentalement hétérogène, réflexif et conflictuel des formes de vie. Ainsi peut émerger une conception bien plus large des possibilités de la critique, ainsi qu’une compréhension alternative (non-conventionnaliste et non-conservatrice) de la politique des formes de vie.
Sovereign Risk Premium and Divergent Fiscal Policies in a Monetary Union
Authors: Badarau Cristina , Huart Florence , Sangaré Ibrahima
Published: April 2015

Pendant la crise de la dette souveraine de la zone euro, les prêteurs sur les marchés financiers ont exigé des primes de risque de défaut souverain plus élevées sur les titres émis par les pays, qui étaient désormais considérés comme trop risqués. Dans certains de ces pays (au premier chef, la Grèce), la politique budgétaire n’avait pas été conduite en respectant les règles européennes. En particulier, le manque de discipline budgétaire provenait de dépenses publiques procycliques. La (sur) réaction des marchés financiers s’est traduite par une forte augmentation du niveau des taux d’intérêt à long terme dans les pays les plus touchés par la crise. Ces pays se sont retrouvés face à de plus grandes difficultés pour essayer de réduire l’endettement public. De plus, le coût d’emprunt pour le secteur privé a augmenté. Dans cet article, nous étudions les effets de chocs asymétriques provoquant une hausse de la prime de risque de défaut souverain dans un pays appartenant à une union monétaire. Nous analysons leurs effets sur l’économie du pays domestique (celui touché par le choc) et les effets de débordement sur le reste de l’union. Pour cela, nous construisons un modèle dynamique stochastique d’équilibre général (DSGE) d’une union monétaire à deux pays, qui est ouverte sur le reste du monde, et dans laquelle les pays membres sont différents au regard de la discipline budgétaire (comportement budgétaire procyclique/contra-cyclique). Nous montrons qu’un tel modèle est adéquat pour expliquer les mécanismes sous-jacents aux performances macroéconomiques divergentes des pays de la zone euro à la suite de la crise de la dette grecque.
Sovereign Default and Bank CDS Payments in Europe
Authors: Vuillemey Guillaume
Published: April 2015

Cet article analyse les effets redistributifs liés aux paiements de CDS en cas de défaut souverain en Europe. Un grand nombre de scénarios de défauts sont simulés en utilisant des données sur les portefeuilles d’obligations et de CDS des banques européennes, ainsi que le cadre théorique développé par Vuillemey et Peltonen [2013]. Nous estimons un modèle probit afin d’examiner, selon quatre critères, les déterminants des effets redistributifs des paiements de CDS entre banques. Les CDS n’ont pas d’effets redistributifs conséquents. Cependant, certaines caractéristiques des groupes bancaires et des entités souveraines sont significativement corrélées avec les paiements de CDS observés. Des résultats supplémentaires ont trait à la magnitude relative des pertes subies par les banques sur leurs portefeuilles obligataires et de CDS.
Public Debt Adjustment in a Simple Model of Stochastic Endogenous Growth
Authors: Menuet Maxime , Villieu Patrick
Published: April 2015

Dans cet article, nous proposons un modèle prototype de croissance endogène stochastique pour étudier les canaux de transmission à travers lesquels la dette publique peut affecter le sentier de croissance potentielle et détériorer la productivité globale des facteurs. Dans un contexte de croissance endogène, les chocs transitoires et la manière dont l’économie s’y adapte, exercent un effet permanent (hysteresis). Nous envisageons ici deux stratégies d’ajustement des finances publiques en réponse à une augmentation de la dette publique causée par un choc technologique néfaste : une stratégie gradualiste ou une thérapie de choc. Notre modèle fait apparaître un arbitrage intertemporel entre ces deux stratégies, la première étant plus favorable à court terme, et la seconde à long terme. De surcroît, l’effet des chocs technologiques est fortement amplifié par le mode d’ajustement de la dette publique, mécanisme que nous qualifions « d’accélérateur de dette publique ».
De l’invisibilité des dispositifs numériques à la légitimation de la communication en entreprise

Published: April 2015

Comment concilier l’incontournable tâche de fournisseur d’outils dans laquelle est cantonnée la communication interne ( ci ) et la quête de reconnaissance à laquelle aspire la fonction ? Cette contribution étudie la tension qui existe entre la demande de légitimité de celle-ci et la mise en invisibilité des dispositifs. Cette dernière renvoie à la problématique de l’usage social, qui peut être analysée à travers trois processus : l’idéalisation de la technique dans les discours, la banalisation des tic dans les pratiques professionnelles et enfin leur légitimation, qui s’appuie sur la justification et l’utilité de leur présence dans les ateliers de production et les bureaux. Le modèle interprétatif de l’enchevêtrement, présenté ici, propose d’analyser comment les outils numériques quittent la sphère des objets techniques énigmatiques pour devenir pour l’utilisateur des dispositifs invisibles. Ceci suscite des paradoxes et enferme la fonction ci dans un cercle vicieux.

Désormais bien installée dans les organisations la communication interne ( ci ) fait l’objet d’évaluations multiples : les mesures d’efficacité ainsi que les outils de reporting tendent à se généraliser. En référence au cadre théorique proposé par Thévenot (2006) et à sa conceptualisation des « régimes d’engagement » , cette contribution montre que les pratiques de mesure et d’évaluation s’inscrivent dans des stratégies de légitimation des professionnels de la ci en réponse à des normes conventionnelles. Elle développe l’hypothèse que l’évaluation de la ci ainsi que celle des praticiens relèvent, de façon distincte, de processus de reconnaissance et contribuent à la formation de l’identité professionnelle des communicants internes.
African edible insects for food and feed: inventory, diversity, commonalities and contribution to food security

Published: April 2015

This paper reviews entomophagy as practised in Africa within the context of food and nutritional security by providing an inventory of the various species of insects that are consumed on the continent and suggests a research for development (R4D) agenda for sustainable utilisation of insects for food and feed. Our survey showed that over 470 species of insects are eaten in Africa. The Central African region remains the most important hotspot of having a culture of entomophagy. The insects mostly eaten in the continent are dominated by the orders Lepidoptera, Orthoptera and Coleoptera. Commonalities were observed across the majority of the insects consumed across Africa, providing opportunities for related R4D activities. An R4D agenda and pathways for using edible insects suggest that socio-economics and marketing studies should address issues of communities’ perceptions, based on their cultural background, income and beliefs. Cost-effective rearing, harvesting and processing technologies are required to prevent depletion and ecological perturbations while ensuring continuous availability of insect-based products. Indigenous reports assert that some edible insects harbour medicinal properties; thus, the need to undertake nutritional and bioactive chemical characterisation of main edible insects along the value chain and to investigate food safety issues such as diseases, allergies, and toxicological and chemical hazards. The use of insects for waste conversion into animal feed and fertiliser requires judicious choice of substrate in view of concerns regarding contaminant loads and pathogens occurrence. Responding to these research needs and opportunities, icipe has recently established an Insects for Food, Feed and Other Uses Programme with well-defined work packages oriented towards attainment of its Vision and Strategy 2013-2020 document, with a strong orientation towards R4D and a focus on activities that lead to adoption and impact on end users, through broad based complementary linkages and partnerships with agriculture and livestock extension services, Food and Agriculture Organization of the United Nations, Consultative Group on International Agricultural Research and advanced research institutes, non-governmental organisations and the private sector.
The protective effect of follicular fluid against the emerging mycotoxins alternariol and beauvericin
Authors: Santos R.R. , Schoevers E.J. , Wu X. , Roelen B.A.J. , Fink-Gremmels J.
Published: April 2015

Porcine granulosa cells were cultured in the absence or presence of 10% porcine follicular fluid (FF) at different concentrations (0-20 μM) of the mycotoxins alternariol (AOH) and beauvericin (BEA). The analyses were performed after exposure to these mycotoxins in a medium supplemented or not with FF harvested from gilts and sows. Cell enzymatic activity and nuclear membrane integrity were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and ethidium homodimer-1 labelling. Trolox equivalent antioxidant capacity was measured to calculate the capacity of the cells to counteract reactive oxygen species. qRT-PCR was used to determine the relative gene expression of efflux transporters (ABCG1 andABCG2) as wellCYP11 andCYP19. Mycotoxin cytotoxicity was more related to enzymatic activity than to nuclear membrane damage and no direct relationship with oxidative stress was observed, except when cells were exposed to AOH. In this case, medium supplementation with FF from sows increased the antioxidant capacity of the cells. AOH did not regulate gene expression in the present conditions, but 5 μM BEA led to the up-regulation ofABCG2 gene expression and a down-regulation ofCYP19 expression. In conclusion, follicular fluid from sows is capable to decrease toxicity of AOH and of BEA.
Patient Selection for Shorter Femoral Stems
Authors: Gruner Andreas , Heller Karl-Dieter
Published: April 2015

The right patient selection with the correct surgical treatment are prerequisite for a positive result in total hip arthroplasty (THA). Short stem implants demand a shorter anchoring length in accordance with the proper indication. Although appropriate indications for short stems have been discussed in the literature, there currently is no clear definition. The lack of an accepted categorization of short hip stems complicates the situation further. This article briefly reviews the literature and highlights the authors’ results and experiences in short stem THA in an effort to establish a proper discrimination between indications and contraindications for the Metha short stem. Results presented include a retrospective data collection and follow-up examination of 126 patients who underwent short stem THA with 2- and 4-year results. Anchoring principles of the short stem are reviewed, and a complication and failure analysis based on 7 femoral revisions in 1092 short stem THAs is presented. Selection criteria for short stem THA are patients younger than 70 years with primary osteoarthritis and dysplastic femoral deformities, and indications of avascular head necrosis. Adequate bone quality must be confirmed intraoperatively, assessing whether the bone structure in the area of the femoral neck is strong enough to support the short stem load transmission. Coxa vara and high dysplastic femoral neck antetorsion are contraindications for short stems. Wide and short femoral necks, implant undersizing, and a deep stem position below the femoral osteotomy compromise stability and must be avoided with an appropriate surgical technique. Long-term data are not yet available.

Authors: Wittenberg Ralf H. , Steffen Reinhard
Published: April 2015

This prospective study investigated revision after modular short stem implantation. Results are presented for 2 different types of neck adapters (titanium and cobalt-chromium [CoCr]). Eighty-five patients with titanium adapters and 87 patients with CoCr adapters underwent follow-up examination after an average of 5.7 and 5.2 years, respectively. Mean patient age was 57 years in both groups. Indications were primary osteoarthritis (80%), cup dysplasia (14%), and other (6%). Mean Harris Hip Scores were 98 and 99 points (titanium and CoCr groups, respectively). Ninety percent and 96% of patients were very satisfied or satisfied (titanium and CoCr groups, respectively); 3% of patients in both groups were dissatisfied. Pain decreased from visual analog scale score 7 and 6 preoperatively to 0.37 and 0.15 postoperatively for the titanium and CoCr groups, respectively. No joint dislocation occurred. Six patients needed revision within the first year (2 for infection, 1 for via falsa position, and 2 for aseptic loosening in the titanium group, and 1 for aseptic loosening in the CoCr group). Nine revisions occurred due to neck adapter failure (titanium group). Primary standard stems were used in all revisions. Excluding material-related adapter failures in the titanium group, the 5-year survival rate was 94.8% (95% confidence interval [CI], 88.9–97.6 for titanium) and 99% (95% CI, 93.7–99.8 for CoCr). No radiographic signs of loosening were seen at last follow-up. Fine sclerotic lines were detected in Gruen zones 1 (17.2%) and 2 (14%), hypertrophies in zone 3 (4.3%), and periprosthetic cancellous bone compressions in zone 6 (75.8%). No adapter fractures occurred for CoCr components. The treatment and anchoring system of the short stem studied yielded good results and allowed revision using standard stems in all patients.

Published: April 2015

IoT (Internet of Things) fuses the physical world and information space. The features of IoT services are different from the traditional Internet services, such as environmental sensitive, event driven, service coordination, complex presentation. The new IoT service architecture should adapt to these features. This paper analyses IoT sensing service characteristics and proposes the future services architecture. It mainly discusses the application layer architecture and the interface presentation technology evolution. In application layer, the traditional SOA architecture is insufficient in the real-time response and parallelism process of services execution, this paper proposes that the new sensing service system architecture may be dominated by EDSOA (Event Driven SOA) architecture to support real-time, concurrency event driven active services execution. At presentation layer, this paper presents the new IoT browser features including using augmented reality technology to input and output, and realize the superposition presentation of the physical world and abstract information. Through a practical application system case - road manhole covers monitoring system to verify the feasibility of the proposed ideas and frameworks.

Cognitive training and assessment refers to ICTs and their relation with students, students with learning disabilities and adults with dementia. This article revises on contemporary research concerning ICTs effectiveness on the training and assessment of attention, memory and executive control functions. Artificial intelligence seems to hold a significant role in the field of cognitive training and rehabilitation as its adaptability and interactivity, enhance users’ motivation and involvement. Moreover, artificial intelligence in combination with other applications provides the means for holistic and cost-effective cognitive interventions through its integrative information processes. Evidently, educators and therapists should advocate of improvements in the engineering features of the applications as well as they should, themselves, expand the implementation of the aforementioned technological innovations in favour of the users’ cognition.
A Hybrid Algorithm for Optimization of Machine Vision Based Tool Position Error
Authors: Mahapatra Prasant Kumar , Garg Anu , Kumar Amod
Published: April 2015

Tool positioning and its error optimization are gaining considerable importance in engineering applications. A number of machine vision systems have been developed for tool wear and conditioning assessment. A machine vision system for lathe tool position and verification was developed. To evaluate the performance of developed system, images of lathe tool were captured before and after the tool movement with a Charge Coupled Device (CCD) camera. The distance traversed by the tool was calculated from the above images. Difference between the calculated (Image based) and the expected tool movement denotes vision based tool position error. In this paper, a novel hybrid (AIS-Bat) algorithm is proposed to optimize this error in the developed vision system. To prove the effectiveness of proposed algorithm, results were compared with mean technique and bat algorithm, it was observed that proposed algorithm outperforms the other two. Although the results seem promising, still there is a need for better image processing techniques before the application of error optimizing hybrid algorithm.
A Straightforward Approach to Estimate the Abnormal Return in Taiwan
Authors: Wei Shih-Yung , Chu Nan-Yu , Hong Wei-Chiang
Published: April 2015

The fluctuation of real estate prices has been a subject of public attention, and related studies are often unable to effectively measure changes due to limitations in information acquisition and modeling. In fact, the existence of abnormal return of the real estate market can be regarded as an important indicator of fluctuations in prices or a bubble. Therefore, based on the Capital Asset Pricing Model, combined with time series analysis, this paper establishes a more convenient method of analysis to explore price changes of Taiwan's real estate market from 1998 to 2012. The empirical results show that there is no abnormal return in Taiwan's overall real estate price changes. However, in major metropolitan areas, abnormal return does exist, and such a trend became more evident after the financial tsunami. By region, the abnormal return rate of New Taipei City has become gradually higher than Taipei City. The findings are consistent with the recent development of the real estate market of the Taipei region, and thus, are worth the attention of the government and relevant sectors.

Published: April 2015

Cloud computing has been proven to have numerous benefits for organizations, especially in supply chain management. More and more organizations have adopted cloud-based solutions to be their primary sourcing applications. Nevertheless, this technology is not without challenges, and in order to deploy and implement cloud-based solutions successfully with minimal risks organizations need to have practical guidance on this emerging technology. Despite the rapid growth of cloud computing in supply chain areas, the existing literature is still conceptual, inadequate, and mainly focused on the pre-adoption stage of this technology. This research examines the post-adoption stage of cloud-based supply chain solutions from the decision science perspective and intends to provide organizations with practical guidance on how to ensure the efficiency of a cloud-based supply chain system and control risks associated with cloud-based solutions.

E-Commerce has become very popular these days because it is convenient, reliable, and fast to use. In spite of these advantages, online buyers often experience difficulty in searching for products on the web, while online businesses are often overwhelmed by the rich data they have collected and find it difficult to promote products appropriate to specific customers. This paper proposes a hybrid recommender system that uses fuzzy logic to intelligently mine the requirements of each specific customer, together with some previous users' opinions about the product, to recommend a list of optimal products to meet users' needs. Experimental results of the proposed system with different brands of laptops prove its effectiveness.
