Oxidative stress is a major cause of islet damage and loss during the islet isolation process. The Nrf2 pathway plays a critical role in protecting the cells against oxidative stress. The aim of this study was to investigate the effect of an Nrf2 activator (dh404) on islet isolation and transplantation in a rodent model. Islet isolation was conducted using Nrf2-deficient and wild-type mice and vehicle-treated and Nrf2 activator (dh404)-treated rats. Islet yield, viability, and Nrf2 pathway activity were determined. An in vivo islet potency test was done. Islet yield and viability in Nrf2-deficient mice was significantly lower compared to wild-type ( p < 0.05) mice. Furthermore, administration of dh404 to normal Sprague–Dawley rats enhanced nuclear translocation of Nrf2 and elevated HO-1 expression in the pancreas. Islet yield and viability in dh404-treated rats was significantly higher compared to the vehicle-treated group ( p < 0.05). The diabetes cure rate in nude mice with chemically induced diabetes was significantly greater in those transplanted with islets from the dh404-treated group (6/9) than vehicle-treated rats (2/9, p < 0.05). The Nrf2 pathway plays a significant role in protecting islets against stress caused by the isolation process. Pharmacological activation of the Nrf2 pathway significantly increased HO-1 expression, improved islet yield, viability, and function after transplantation.

Published: October 2015

Alzheimer's disease (AD) is the fourth major cause of mortality in the elderly in the US and the leading cause of dementia worldwide. While pharmacological targets have been discovered, there are no true disease-modifying therapies. We have recently discovered that multiple low-dose infusions of human umbilical cord blood cells (HUCBCs) ameliorate cognitive impairments and reduce Aβ-associated neuropathology in PSAPP transgenic mice. However, the mechanism for these effects of HUCBCs remains unclear. In the present study, we examined whether monocytes, as important components of HUCBCs, would have beneficial outcomes on the reduction of AD-like pathology and associated cognitive impairments in PSAPP transgenic AD model mice. PSAPP mice and their wild-type littermates were treated monthly with an infusion of peripheral human umbilical cord blood cell (HUCBC)-derived monocytes over a period of 2 and 4 months, followed by behavioral evaluations, biochemical, and histological analyses. The principal findings of the present study confirmed that monocytes derived from HUCBCs (CB-M) play a central role in HUCBC-mediated cognition-enhancing and Aβ pathology-ameliorating activities. Most importantly, we found that compared with CB-M, aged monocytes showed an ineffective phagocytosis of Aβ, while exogenous soluble amyloid precursor protein α (sAPPα) could reverse this deficiency. Pretreating monocytes with sAPPα upregulates Aβ internalization. Our further studies suggested that sAPPα could form a heterodimer with Aβs, with the APP672-688 (Aβ1-16) region being responsible for this effect. This in turn promoted binding of these heterodimers to monocyte scavenger receptors and thus promoted enhanced Aβ clearance. In summary, our findings suggest an interesting hypothesis that peripheral monocytes contribute to Aβ clearance through heterodimerization of sAPPα with Aβ. Further, declined or impaired sAPPaα production, or reduced heterodimerization with Aβ, would cause a deficiency in Aβ clearance and thus accelerate the pathogenesis of AD.
TOPOGRAPHY OF A DREAM, OR SOME FEATURES OF NONLINEAR NARRATIVE
Authors: Keturakis Saulius
Published: October 2015

The article deals with the turn of the poetry of linear narrative into three-dimensional shapes, while topography and other spatial disciplines becomes an important tool to understand the meaning of new hypertextual narrative. Relying on the metaphors of Ted Nelson, the creator of the concept of hypertext about the magical and oneiric nature of a nonlinear story, the article represents the relationships between the topography of the spiritual world of the British Romanticism, written media transformation to a three-dimensional spatial structure in Nelson’s hypertext project and postmodern practices of cultural dismantling. The article concludes that the traditional writing about hypertext is often not able to cover part of its features; the attention is drawn to the nature of hybrid art/scientific analysis of the new, intermedial “writing”.

Introduction: Extraintestinal pathogenic Escherichia coli (ExPEC) is associated with various diseases such as urinary tract infections, neonatal meningitis and septicemia. There are many virulence factors (VF) encoded by genes in ExPEC, including papC, papG, ecpA, iroN, fyuA, iutA, ompTp, tsh, hlyF, hlyA and iss. These virulence genes may be present in pathogenicity islands (PAI) or plasmids. Methodology: In this study, we analyzed the presence of VF encoding genes, PAI sequences and phylogenetic groups of 96 ExPEC strains isolated from the urine and blood of patients at the University Hospital of Londrina, and we compared them with 50 faecal commensal strains from healthy individuals. Results: The VF fyuA (65.60%) was detected in pathogenic strains and commensal strains (46%). A comparison of the distribution of ExPEC and commensal strains in the phylogenetic groups showed that more ExPEC strains belonged to group B2 whereas more of the commensal isolates belonged to group A. The distribution of the seven PAI sequences between commensal strains and ExPEC strains showed that PAI IV536 was common in both ExPEC and commensal isolates. Conclusions: These results showed that the ExPEC strains that belonged to group B2 had more PAI sequences compared to those of the other groups, especially group B1, which had virulence genes but the lowest percentage of PAI sequences, which leads us to conclude that the virulence of ExPEC strains characterized as B2 is likely attributed to PAI encoded genes, whereas the virulence of ExPEC strains belonging to phylogenetic group B1 is likely due to plasmid encoded virulence genes.
Healthcare-associated infections in Intensive Care Units: epidemiology and infection control in low-to-middle income countries
Authors: Alp Emine , Damani Nizam
Published: October 2015

Healthcare-associated infections (HAIs) are major patient safety problems in hospitals, especially in intensive care units (ICUs). Patients in ICUs are prone to HAIs due to reduced host defense mechanisms, low compliance with infection prevention and control (IPC) measures due to lack of education and training, and heavy workload and low staffing levels, leading to cross-transmission of microorganisms from patient to patient. Patients with HAIs have prolonged hospital stays, and have high morbidity and mortality, thus adding economic burden on the healthcare system. For various reasons, in low-to-middle income countries (LMICs), the scale of the problem is huge; each year, many people die from HAIs. In this review, epidemiology of HAIs and infection prevention and control measures in ICUs is discussed, with especial emphasis on LMICs. High rates of HAIs caused by multidrug-resistant organisms (MDROs) are serious problems in ICUs in LMICs. In view of increasing prevalence of MDROs, LMICs should establish effective IPC infrastructure, appoint IPC teams, and provide adequate training and resources. These resources to establish and appoint IPC teams can be released by avoiding ritualistic, wasteful, and unsafe IPC practices, and by diverting resources to implement basic IPC measures, including early detection of infection, isolation of patients, application of appropriate IPC precautions, adherence to hand hygiene, and implementation of HAIs care bundles and basic evidence-based practices.

La professionnalisation des relations de care : le cas des référents de parcours de santé à l’Association Française contre les Myopathies
Authors: André Kévin
Published: October 2015

Si les relations de care émergent de manière spontanée dans le contexte domestique (Noddings, 1984), certains auteurs plaident pour la reconnaissance de leur rôle en dehors de la sphère privée (Tronto, 2009), notamment dans le contexte de la prise en charge des personnes en situation de dépendance (Winnicott, 1970). Nous nous appuyons sur une recherche menée au sein de l’Association Française contre les Myopathies (AFM) pour étudier en quoi les « Référents de Parcours de Santé » de l’AFM peuvent être qualifiés de professionnels du care . Nous discutons des conditions qui permettent une professionnalisation du care et des implications pour une meilleure continuité des soins.
Les facteurs explicatifs de la modification récurrente des ressources et compétences : le cas de la capacité dynamique d’acquisition d’entreprise
Authors: Altintas Gulsun
Published: October 2015

L’objectif de cet article est d’identifier les facteurs qui favorisent la modification récurrente des ressources et des compétences. Pour ce faire, nous étudions la capacité dynamique d’acquisition d’entreprise dans une approche de récurrence. Notre recherche repose sur une démarche d’étude de cas longitudinale menée au sein d’un tour-opérateur. Nos résultats permettent de comprendre que la capacité dynamique d’acquisition d’entreprise se forme lors d’un processus d’expérimentation. Ce processus est de nouveau mis en œuvre à l’identique lorsque l’opportunité se présente : ce qui caractérise la récurrence de la capacité dynamique. Trois facteurs sont à l’origine de la récurrence de la capacité dynamique et donc de la modification récurrente des ressources et compétences : l’apprentissage expérimental, l’intentionnalité managériale et l’activité de reporting. Nous montrons également que ces trois facteurs s’articulent et interagissent entre eux.
L’approche non médicamenteuse de la personne âgée atteinte de maladie d’Alzheimer et apparentées
Authors: Engasser Ophélie , Bonnet Agnès , Quaderi André
Published: October 2015

La maladie d’Alzheimer et maladies apparentées (MAA) sont des affections neurodégénératives à évolution inéluctable, induisant divers troubles du comportement. Les limites de l’approche médicamenteuse (HAS, 2008) nécessitent un développement des approches non pharmacologiques. Les recherches les plus importantes sur la question sont basées sur le recours à la médiation sensorielle. Elles montrent une variation possible de l’intensité des troubles comportementaux dans les MAA. Les travaux laissent toutefois ouverte la question des fondements clinico-théoriques de ces approches. Cet article propose de les explorer en prenant appui sur une approche écologique du sujet atteint de MAA, étayée des paradigmes de la psychopathologie psychanalytique.
Psychothérapie en milieu carcéral. Le cadre à l’épreuve de l’emprise
Authors: Pelladeau Élise , de Kernier Nathalie
Published: October 2015

Cet article présente le cas d’un patient suivi pendant plusieurs années en psychothérapie, en unité de soins, alors qu’il était incarcéré et condamné à 15 ans de réclusion criminelle pour un homicide volontaire. Il traite de l’évolution de la relation thérapeutique au fil des années, en soulignant les réaménagements libidinaux engagés dans le transfert avec la thérapeute. Ici, le travail thérapeutique a notamment aidé le jeune adulte à s’acheminer vers une restauration narcissique, en s’appuyant sur ses fantasmes pour se construire et non pour les considérer comme des persécuteurs. La création progressive d’enveloppes contenantes et d’un espace psychique a pu permettre la relance de processus d’intériorisation et de mentalisation.
Lecture clinique et projective du refus d’engagement dans la thérapie chez une femme victime d’inceste
Authors: Mazoyer Anne-Valérie , Sanchez Caroline
Published: October 2015

L’objectif de cet article est de montrer comment la méthodologie projective se référant à la métapsychologie freudienne peut servir de réflexion à la clinique de l’inceste et plus particulièrement au refus d’engagement des sujets dans une aide thérapeutique malgré un investissement dans la vie associative auprès des victimes. Nous avons procédé à des entretiens de recherche et à une méthodologie projective auprès d’une patiente qui a présenté de bonnes capacités d’expression et de verbalisation de son vécu incestueux. Après une revue de la littérature, nous avons dégagé des indicateurs nous permettant de mieux repérer l’investissement ou au contraire l’impossibilité à investir une relation objectale de qualité. L’impossibilité de représentation de relation positive au Rorschach traduirait chez notre sujet les entraves à la constitution d’une alliance thérapeutique. La proximité jugée affolante avec l’autre engage la jeune femme à préférer un engagement associatif avec des victimes de pédocriminalité. Le détour par cette situation nous conduit à considérer nos mouvements contre-transférentiels afin de mieux accompagner ces sujets sans tomber dans la distance horrifiée ni dans l’écoute sympathique sans effets sur l’appropriation subjective du trauma.
L’alcoolisme féminin : une solution au ravage ?
Authors: Cloës Claude
Published: October 2015

Le XXI e siècle serait-il celui des addictions ? La clinique psychiatrique quotidienne tend à nous le faire supposer en raison de la multiplicité des problématiques addictives que l’on y rencontre, addictions à l’alcool le plus souvent. Si l’on admet que tout sujet peut devenir addict, peut-on repérer une spécificité dans l’apparition de conduites alcooliques chez les femmes ? L’alcool survient-il à un moment particulier dans leur vie, en lien avec un désir de maternité ignoré ou empêché ? Voilà l’énigme que nous pose la clinique et à laquelle nous proposons de réfléchir. Les récits cliniques de deux femmes addictes à l’alcool nous feront approcher la figure du ravage mère-fille non dépassé, offrant d’envisager l’alcoolisme féminin comme une solution face à ce ravage – une solution passionnelle qui est tout à la fois le remède et le poison pour le sujet qui s’y inscrit.
Does Trust Mean Giving and not Risking? Experimental Evidence from the Trust Game
Authors: Garapin Alexis , Muller Laurent , Rahali Bilel
Published: October 2015

Dans une expérience en laboratoire, nous cherchons à déterminer si la confiance est plutôt fondée sur l’attention à l’autre ou sur la prise de risque. Nous élicitons les préférences sociales des participants avec le test dit « de l’anneau » (Griesinger et Livingston [1973]) et les préférences pour le risque avec le test de Holt et Laury [2002]. Ces mesures sont ensuite exploitées dans deux versions du jeu de l’investissement : (i) la version standard, qui, par construction, intègre une part de risque (à travers l’anticipation stratégique d’un retour sur investissement) et ii) une autre version (appelée « jeu du dictateur triple » dans la littérature) dans laquelle cette part de risque est éliminée. Les mesures issues des tests d’élicitation des préférences sont aussi utilisées pour expliquer les écarts entre les montants investis dans les deux jeux. Les résultats de l’expérience montrent que ce sont plutôt les préférences sociales qui fondent les comportements d’investissement. En revanche, les écarts entre les montants investis et les mesures des préférences ne sont pas corrélés.

Published: October 2015

In this work Y3Ga5O12 doped with 8.7 mol% Cr3+ (YGG:Cr) far-red phosphor pellets calcined at 1000, 1200, 1300, and 1400 °C temperatures were synthesized by a simple and low cost sol–gel method. The YGG:Cr pellets were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM) and the luminescent properties were studied by measuring diffuse reflection, photoluminescence (PL), PL excitation (PLE) and internal quantum efficiency (QE). The XRD and SEM results have shown that the material becomes more crystalline, uniform and less porous for higher calcination temperatures. XRD results have also shown that the material becomes strained due to the doping with Cr3+ ions for the calcination temperature of 1400 °C. The diffuse reflection and PLE spectra have shown three absorption and excitation bands in the UV, blue and red spectral regions. PL was characterized by a broad band in the far-red spectral region that peaked at about 711 nm. QE has shown a strong dependence on the calcination temperature. Furthermore, using the previously synthesized YGG:Cr phosphor powder and a commercial blue InGaN LED, a far-red–blue phosphor converted LED (pcLED) lamp was designed and characterized. Blue–far-red pcLEDs could be used in greenhouses in order to meet the photophysiological needs of plants.

Authors: Wu Feng , Zhu Jiang , Tian Yilong , Xi Zhipeng
Published: October 2015

Network capacity has been widely studied in recent years. However, most of the literatures focus on the networks where nodes are distributed in a two-dimensional space. In this paper, we propose a 3D hybrid sensor network model. By setting different sensor node distribution probabilities for cells, we divide all the cells in the network into dense cells and sparse cells. Analytical expressions of the aggregate throughput capacity are obtained. We also find that suitable inhomogeneity can increase the network throughput capacity.

The security issues of Wireless Sensor Network (WSN) are significant, among which intrusion detection can improve the defense detection performance of WSN, and also balance the security and energy-saving accurately and efficiently. In this paper, we focus on the intrusion detection problem in WSN. Specifically, we propose a cluster-based collaborative detection structure, and the detection algorithm is based on immunity system and Ant Colony Optimization (ACO). The basic idea is to formulate intrusion detection as an optimization problem and introduce immune mechanism into ACO during iterations. Finally, the experiment shows that proposed algorithm outperforms other methods.

Published: October 2015

Sigma-Delta (∑∆) modulators are commonly used in high-resolution analog-to-digital converters (ADCs). In this paper, a high-performance modulator targeted for ultra-high-frequency (UHF) radio-frequency identification (RFID) zero-intermediate frequency (ZIF) receivers is designed in standard 0.18μm CMOS technology. The modulator has been designed with switched-capacitor (SC) integrators employing gain-boosted operational amplifiers, voltage comparators and nonoverlapping clock generators to satisfy such requirements as high gain, low voltage and wide bandwidth. The behavioral-level modeling and circuit-level design are carried out with MATLAB/Simulink and Cadence/SpectreRF, respectively. Ultimately, the high-speed and low-power realization of a second-order single-bit modulator with an oversampling ratio (OSR) of 32 is presented. Simulation results shown that, from a 1.8V supply, operated at a sampling frequency of 64MHz, a dynamic range of 53.4dB over a signal bandwidth of 1MHz is achieved.

Authors: HU Shan Wen , Shi Long Xing , Li G.P.
Published: October 2015

Hetero-junction Bipolar Transistors (HBTs) have become very promising devices for power amplifier design in different communication applications. This paper proposes an analytical large signal model to predict nonlinear behavior of InGaP/GaAs HBT. The proposed model is directly fitted from linear model elements using Fourier transfer functions. As a consequence, the proposed large signal model shows good insight of circuit nonlinear behavior, and can be used to analysis large signal parameters of power amplifier. Based on the proposed large signal model, power gain and phase variation of an emitter follower amplify stage under different bias conditions have been analyzed. The calculated results show that: both gain and phase properties exhibit reverse deviation in saturation compared with that in forward amplify region, and can be used to maximize the linearity of power amplifier.

Real-name policy has been adopted in some specific fields of China for several years. As the leading micro-blogging service of China, Weibo has introduced the real name policy in 2012. However, the question is that how the real-name policy is used is still unknown. In this paper, with a dataset of 158,979 accounts crawled from Weibo, we conduct a deep measurement and analysis on the use of real-name policy. We find that although the rule has been promoted for several years, the proportion of verified users is still small. Our work also shows that famous people tend to use their real names to gain more public attentions. And a verified user is more likely to be followed by others.

The Research of 3D Mouth Animation Synthesis Driven by Continuous Chinese Text Based on Mpeg-4
Authors: Wang Yue , Han Hui Jian
Published: October 2015

A 3D human facial model was made based on the MPEG-4 standard. A method of synthesis of mouth animation based on a entire Chinese sentence was put forward, according to the influence of Chinese pronunciation rules such as co-articulation sufficiently. The method computes the extent of influence between current phoneme and the one next to it, and constructs the continuous mouth-shape sequence. Then filter the phoneme which has little effect on the last and the next one when pronouncing continuously. The 3D facial model was driven to synthesize smooth and realistic animation. After the experiments, it is proved that the method has a good versatility and reliability, which can be used on different kinds of 3D models. At the same time, the method can effectively improve the problem of co-articulation in continuous Chinese pronunciation, which makes the synthesis of mouth animation more smooth, more fluent, and more close to real pronunciation of people.

Published: October 2015

As the development of the mobile communication and the computational capability of the mobile terminals, more users use their mobile devices to play music. In this work, an online music recommendation system is designed for mobile services, which consists of two modules: offline processing and online recommendation. The offline module labels all the music into different categories, by which the music items libraries corresponding to the tags are constructed and the rating matrixs are consequently built. The online module integrates the context information, by which the matched rating matrix is retrieved. By using the collaborative filtering model with matrix completion algorithm, the music recommendations that suit the user and the situation are offered. The proposed recommendation system improves the precision of the recommendation by integration the context information of the users, and augments the online computational capability because the matrix scale is reduced by constructing the rating matrices for the music in the different tag libraries. A large number of experiments demonstrate that the proposed system is designed to be robust and effective to the music recommendation and efficient to the online recommendation for the mobile services.
