There are extraordinary opportunities to reduce the consumption of fossil energy as a result of retrofitting the existing buildings in Egypt. For instance, Cairo falls in the arid climate zone with an annual total radiation above 2409 bankable kWh/m2 per annum with approximately 3300 hours of full sunshine. However, the poorly insulated fabric of most buildings shows relatively high demand for cooling and heating energy. To overcome this problem and to examine these opportunities, this study evaluates the retrofit of a middle-income urban residential case in Cairo. The aim of the study is to investigate the potential and impact of retrofits on two different scales. The first is on the building scale, intending to reach a low-energy performance. The second is on a community scale, intending to increase the dependence on renewable sources. The case study employed TRNSYS to evaluate the performance and energy/carbon emissions savings. The research took in consideration passive and active design strategies such as envelope retrofit, internal loads reduction, and natural ventilation; in addition to domestic water heating, photovoltaic panels and solar thermal air conditioning. The results were evaluated to assess the suitability of each strategy based on energy performance. The final result of this study shows the feasibility of improving the envelope performance and installing solar hot water collectors and solar thermal air conditioning. The low-energy retrofit for old residential buildings leads to significant savings in energy consumption when applied on community scale rather than building scale. However, it is urgent to set energy conservation and code-enforced retrofit measures to start a national retrofit process. [less ▲]

One of the primary objectives of landscape architecture in hot areas is to improve the micro-climate passively by modifying the extremes of particular environmental conditions through increasing or decreasing the effect of prevailing conditions. In hot arid climates, we wish to make the outdoor environment cooler, breezier and more humid. This happens through planting vegetation as different design elements, e.g. shelterbelts, wind barriers, wind filter or water elements. This paper attempts to endorse the Bioclimatic-Zones Concept, as a passive landscape design strategy for site planning, in hot arid climates. In essence, we are attempting to create bioclimatic zones. Each zone should specifically fulfill certain desired climatic improvements through a group of design decisions. This happens through the intensive or extensive use of plants materials and water elements. Helwan University Campus was employed as a case study to assess and verify this design strategy. Some methodologies such as field measurements and computer simulations (ENVI-MET) were employed. This paper presents the more interesting result and explains why this concept was successful and how the Bioclimatic-Zones Concept improved the micro-climate. [less ▲]

Toute formation supérieure a ses principes et ses particularités visant à développer des compétences en relation avec les finalités professionnelles disponibles. La formation des éducateurs sportifs est l'une des préoccupation majeurs de toutes les sociétés cherchant le progrès et le développement, il existe de nombreuses raisons pour lesquelles les nouveaux étudiants choisissent leur avenir universitaire ou professionnel, ils abordent l'enseignement supérieur avec des dispositions diverses à l'égard du contenu de la formation et des professions sur lesquelles elle débouche. Ce travail se situe dans le champ de l’éducation comparée. Il propose une lecture compréhensive de deux systèmes de formation dans un esprit d’ouverture et d’élargissement des connaissances. En nous inspirant de deux études effectuées dans le domaine de la formation des éducateurs physiques dans des contextes culturels très différents (Groupe de recherche de MJS, 1983, pour l’Algérie – Groupe de recherche interuniversitaire, 2003, pour la Belgique francophone). L’objectif de cette recherche a dès lors consisté à déterminer les motifs qui incitent les étudiants à s'inscrirent aux études de diverses formations sportives, qu’ils soient universitaires ou non. Notre recherche s’est basée, d’une part, sur l’analyse des textes officiels relatifs à l’organisation des études supérieures dans le domaine sportif et, d’autre part, sur des données collectées auprès des acteurs impliqués dans quatre institutions de formation, deux de la région d’Alger et deux de la région liégeoise. Il convient de retenir que, dans chaque contexte culturel, une institution universitaire et une non universitaire ont été analysées. Nos résultats portent ainsi sur un échantillon total de 290 sujets (40 membres des staffs pédagogiques, 108 étudiants et 142 diplômés). Les formateurs ont été interviewés tandis que les sujets des deux autres groupes ont répondu à des questionnaires. La version arabe de chaque instrument a été traduite à partir des outils en français. Un expert en a assuré le contrôle de validité. Dans cet article, nous porterons notre attention sur l’analyse des réponses fournies par les trois types d’acteurs à deux questions fermées consistant à identifier le degré d’importance accordé par les sujets à des motifs d'inscription aux études en éducation physique et sportive, par l’intermédiaire d’échelles de Lickert à quatre niveaux. Les réponses ont été encodées dans une base de données informatique et traitées au moyen du logiciel Statistica (Stat Soft, 2006). Aucune différence significative n’est enregistrée dans la comparaison des réponses des sujets interrogés. Nous constatons toutefois que, d'une part, l'amour du sport et la volonté de pratiquer du sport sont parmi les plus importants des motifs de suivre cette formation, et d'autre part, dans les deux institutions belges, une importance plus grande est donnée à l'entraînement sportif, le contexte culturel ne semble pas non plus beaucoup influencer les avis des sujets interrogés.

Generally conceptualized at an intra-organizational level, ambidexterity can also appear at an inter-organizational level when organizations decide to collaborate and distribute activities of exploration and activities of exploitation according to their specialty. In this paper, we investigate these collaborations, often presented as win-win solutions. On the basis of two case studies of R&D partnerships benefiting from regional subsidies, we show the tensions which cross these alliances and the controversies which divide the partners. Our analysis, based on actor-network theory, indicates that the conditions of a successful inter-organizational ambidexterity do not exist a priori. The success of the partnership rather rests on a continuous translation process creating the convergence between the stakeholders. [less ▲]

Using quality-of-service (QoS) metrics for Internet traffic is expected to improve greatly the performance of many network enabled applications, such as Voice-over-IP (VoIP) and video conferencing. However, it is not possible to constantly measure path performance metrics (PPMs) such as delay and throughput without interfering with the network. In this work, we focus on PPMs measurement scalability by considering machine learning techniques to estimate predictive models from past PPMs observations. Using real data collected from PlanetLab, we provide a comparison between three different predictors: AR(MA) models, Kalman filters and support vector machines (SVMs). Some predic- tors use delay and throughput jointly to take advantage of the possible relationship between PPMs, while other predictors consider PPMs individually. Our current results illustrate that the best performing model is an individual SVM specific to each time series. Overall, delay can be predicted with very good accuracy while accurate forecasting of throughput remains an open problem. [less ▲]

Introduction Treatment or training sessions with neuromuscular electrical stimulations (NMES) are generally performed in a transcutaneous manner with the aid of surface electrodes. Several investigators have highlighted the benefits of quadriceps stimulation during rehabilitation following traumatic injury or surgery of the knee and during physical preparation of athletes (Kramer and Mendryyk, 1982). However, the practical modalities of quadriceps stimulation (number, size and localization of electrodes) remain controversial (Vanderthommen and Duchateau, 2007). The present work aimed to determine the optimal electrodes setting for NMES applied to the quadriceps. Methods Twenty physically active men (23 ± 2 years, 180 ± 8 cm, 75 ± 12 Kg) underwent first an evaluation of left quadriceps maximal isometric voluntary torque (QMIVT). The exact localization of the motor points of vastus medialis (MPVM) and vastus lateralis (MPVL) was also determined. Then, we tested unilaterally, isometrically and consecutively five electrodes settings (ES) including rectangular (10 x 5 cm) (RE) or square (5 x 5 cm) (SE) electrodes, with identical stimulation parameters (biphasic symmetric rectangular pulses, 80 Hz, pulse duration 0.35 ms, constant current intensity (42 ± 11 mA)): ES1= 1 channel, 2 RE transversally on the thigh (with the distal electrode placed on MPVM and MPVL); ES2= 1 channel, 2 RE longitudinally on MPVM and MPVL; ES3= 1 channel, 2 SE on MPVM and MPVL; ES4= 2 channels, 4 SE (with 2 SE placed on MPVM and MPVL); ES5= 2 channels, channel 1= 1 SE on MPVM and 1 RE transversally on the proximal part of the thigh, channel 2= 1 SE on MPVL and 1 RE transversally on the proximal part of the thigh. For each ES we measured the electrostimulated torque. Results The mean QMIVT reached 200 ± 51 Nm. The MPVM and MPVL were situated 10 ± 2 cm and 14 ± 3 from the patellar base, respectively. The stimulated contractions reached 9.2 ± 7.4 Nm (4.6% of QMIVT) for ES1, 8 ± 4.8 Nm (4% of QMIVT) for ES2, 15 ± 8.3 Nm (7.5% of QMIVT) for ES3, 16.3 ± 7.7 Nm (8.2% of QMIVT) for ES4 and 40.4 ± 11.3 Nm (20.2% of QMIVT) for ES5 (p<0.05). Discussion During NMES programs it appears crucial to use a proper electrode setting ensuring efficient muscle recruitment and therefore optimized training effects. However, physiotherapists and trainers often place electrodes empirically especially for NMES applied to the quadriceps. This study demonstrated the relevance of using two channels for quadriceps NMES and of setting, for each channel, one small “excitative” electrode exactly on the motor point of vastus medialis or lateralis and one bigger “dispersive” electrode transversally on the proximal part of the thigh (in order to close the circuit).

Despite considerable recent work on soil heterotrophic respiration, a mechanistic understanding of this process is still missing. Temperature is one of the most important driving factors. It can influence the mechanism through multiple ways, whose importance may vary with time. An incubation experiment is set up to study short-term temperature influences on soil microbial respiration and its evolution through time. Soil samples are taken in spring from the surface layer (0-25cm) of a bare agricultural loamy soil situated in Lonzée in Belgium (Hesbaye region) and are homogenized before being placed into incubators at three different temperatures, namely 5, 15 and 25°C. Temperature is regulated by Peltier systems that warm up or cool down a sand bath containing jars with soil samples. Once a week, incubation temperatures are increased and decreased by 5°C-steps, starting from each incubator temperature, to achieve a one-day temperature cycle between 5 and 35°C. CO2 flux measurements are performed at each temperature step by a closed dynamic chamber system, after the temperature has stabilized in the samples. Microbial biomass (C and N) is determined four times during the temperature cycle by the fumigation-extraction technique and soil labile carbon is measured at the beginning of each cycle by the hot-water extraction method. Moisture levels in soil samples are regularly checked and adjusted to keep optimal soil moisture content. Between CO2 flux measurements, jars are left open to ensure that anaerobic conditions do not occur. Further investigations could include an assessment of the importance of substrate availability and depletion on microbial activity, and a model development related to the results provided by this experiment.

The motivation for this paper is to focus on the better understanding of flapping wing flight, including flapping flight involving high pitching amplitudes. The investigation will be primarily experimental. The experiment will utilize a mechanical flapping and pitching wind tunnel model, which is modeled on large migrating birds. The 3-D rectangular wings are forced to flap and pitch sinusoidally in a low speed wind tunnel. The unsteady aerodynamic forces generated are measured using a three-component force balance. The main objective of this work is to investigate the effect that varying the oscillation parameters has on the aerodynamic forces acting on the 3-D wing undergoing flapping and pitching. The parameters in question are reduced frequency, flapping ampli- tude and pitching amplitude. Comparisons are made with aerodynamic force predictions obtained from unsteady vortex lattice calculations. [less ▲]

In Cairo, the amount of green space per inhabitant is roughly equivalent to 0.33 square meters per person (3.5 square feet), one of the lowest proportions in the world. Green roofs are presented in this study mainly as an urban landscape for healthy and productive cities. This paper describes the idea of green roofs as platform for urban faming that is considered as a holistic approach to solve environmental, spatial, social and economic problems in large cities in the developing countries. The first part of the study, presents the theoretical framework for roof farming. Potentials and problems of green roofs are analyzed and mapped in a multilayered method. The goal is to find out what the maximum potentials of productive green rooftops and determine the best techniques for maintaining them. As a result, the research presents a set of design principles, guidelines and tools that can assist in transforming existing roofs into productive roof farms. The second part of the study examines successful case studies in Cairo, including schools and residential units and introduces a broader function of roof gardens, as well as the barriers for successful implementation. The final result, point to the importance of considering green roofs as creative development opportunity for urban open spaces, responsive support for bio and food security, in addition to the climatic, environmental and aesthetical benefits. Finally, the paper presents the more interesting results and explains why this approach is successful and how the results can be extended to other cities. [less ▲]

Introduction: Although previous research highlighted the importance of automatic and unconscious inhibition in motor control, the neural correlates of such processes remain unclear. Basal ganglia dysfunctions have long been associated with impairment in automatic motor control. In addition, Sumner & al. (2007) suggested a key role of the medial frontal cortex by administrating a masked priming task (e.g., Eimer & Schlaghecken 2003) to a patient with a small lesion restricted to the supplementary motor area (SMA)., Here, we used fMRI in normal subjects to better delineate the respective roles of SMA and basal ganglia in automatic and unconscious motor inhibition. Methods: We used event-related BOLD fMRI at 3T to record brain activity in 26 healthy volunteers (22 ± 2 years) as they performed the subliminal masked priming task. In this visuomotor task, participants are asked to make speeded button presses with the left or right hand following leftward or rightward pointing arrows, which are preceded by masked prime arrows. Here, two experimental variables were manipulated: the interval between the mask and the target (SOA: 0,100,150,200 or 250 ms) and the prime/target direction (compatible or incompatible). Imaging data processing and analysis were performed using SPM8b. Results: using Repeated Measures ANOVA of behavioral data (global interaction SOA*compatibility, p<0.0000001), we replicated the masked priming effects showing faster reaction times (i.e., motor response facilitation) in compatible than incompatible trials at 0-SOA (positive compatibility effect: diff = 21 ms, linear contrast : p<0.0000001) and the reverse (negative compatibility effect) at 100 (diff = -12 ms, p= 0.01) and 150-SOA (diff= -12 ms, p= 0.008) suggesting motor response inhibition. At 200 & 250 SOA, we no longer found significant compatibility effects (p>0.05) By applying a similar statistical model to imaging data, we observed a stronger activity in the in several regions, the SMA (p<0.001, uncorrected), caudate (p=0.002, uncorrected) and thalamus (p<0.001, uncorrected) showing stronger activity in compatible than incompatible trials at 100 and 150-SOA, as compared with 0-SOA. Moreover, the differential activity in the SMA was correlated with the negative compatibility effect (p= 0.01). When testing for a main effect of SOAs we didn’t find a differential activation of the SMA, but a stronger deactivation of the caudate (p=0.009, uncorrected) and the thalamus (p=0.007, uncorrected) at 100-150 SOA (inhibition conditions) compared to 0-SOA (facilitation condition). In a prime identification task administered after the fMRI experiment, subjects’ performance was at chance levels for primes displayed for 17 ms as in the main study, suggesting that the prime was not consciously perceived. Conclusions: These new findings suggest that automatic and unconscious inhibition of an activated motor response is mediated by the basal ganglia whereas medial frontal regions seem to be more implicated in the control of response conflict related to inhibition.

The Discrete Vortex Method (DVM) has been recently used by several researchers in order to simulate the dynamic stall phenomenon on 2D airfoils oscillating at high angles of attack or undergoing stall flutter oscillations. The aim of the present work is to investigate whether such simulations are representative of the true physics governing such oscillation. A DVM method is described and implemented. A basic validation of the method is performed on the case of an impulsively started static airfoil at a low angle of attack. It is shown that the steady state lift value obtained from the DVM method agrees with experimental measurements. Subsequently, a DVM simulation is performed for the case of a NACA 0012 airfoil undergoing symmetric stall flutter oscillations. The simulation results are compared to experimental results. It is shown that, while the general shape of the simulated lift variation with time agrees with the experiment, there are significant mean value and phase differences between experiment and simulation. Several justifications are suggested and improvements to the DVM simulation proposed. [less ▲]

Management of water resource systems includes adequate decisions about groundwater resource protection. Groundwater vulnerability maps can greatly help for these decisions. In the vulnerability assessment, physical attributes are often mixed with conventional priorities implicitly embedded in the applied methods. Results from one or another method can consequently be very dissimilar and decision makers are losing confidence in these tools. A methodology is proposed to reframe the groundwater vulnerability assessment in a Pressure-State-Impact causal chain that is familiar to decision makers. The physically-based analysis is clearly separated from the agreement aspects induced by local societal, environmental or political priorities. An example is given and perspectives of generalisation are evoked. [less ▲]

The evolutions of atmospheric CO2 partial pressure (pCO2) and of the carbonate compensation depth and the calcite and aragonite saturation horizons (CSH and ASH, respectively) have been studied with the coupled oceansediment model MBM-MEDUSA [1], over the next 50,000 years. MBM-MEDUSA includes a full description of sedimentary exchange processes, taking into account chemical carbonate erosion in a consistent way. The adopted emission scenarios were based upon logistic functions [2], considering total emissions of 500, 1000, 2000 and 4240 GtC); the adopted stabilisation scenarios were the S350, S450, S550, S650 and S750 from the IPCC [3]. While the evolutions of atmospheric pCO2 and pH have got a great deal of attention so far (e.g., [4, 5]), only a few studies have considered the saturation horizons [5, 6], and, to our best knowledge, this is the first study also focusing on compensation depth variations. Simulation experiments were started with a 50,000 year spin-up to 1750 A.D. (at steady state). This state was characterised by an atmospheric pCO2 of 277 ppm, a CSH depth of 3350 m and a CCD of 4300 m (in the Indo-Pacific, which can be considered the most representative reservoir for the global ocean). In all experiments, we found that CCD variations were considerably greater than CSH variations. The 500 GtC emission scenario yielded CSH and CCD maximum shoalings of 450 and 800 m, respectively, in the year 3400 A.D. about; with the 4240 GtC emission scenario, both CSH and CCD became shallower than 500 m in 2650 A.D. With the highly optimistic S350 stabilisation scenario, CSH and CCD become even shallower than with the 500 GtC emission scenario (650 m and 1000 m shoaling, respectively), although in the year 5000 A.D. only. For the close-to-CO2-doubling scenario S550, CSH and CCD shoaled by about 1950 and 2450 m (to depths of 1400 and 1900 m, respectively). As a result, most of the sea-floor environment bathed in water that was highly corrosive to carbonate material. In the S650 and S750 scenarios experiments, the CCD becomes shallower than 500 m, leaving little space for benthic carbonate producers to survive. [1] Munhoven (2007) Deep-Sea Res. II 54, 722-746.

In 1998, the French Parliament enacted a law regarding the struggle against discrimination . In response to this legislation, the French Minister of Justice implemented a new judicial structure (the "Houses of Law") in areas which had been defined as "districts in difficulty" or "areas where the law is not applied anymore." The purpose of this structure was to provide advice to inner city inhabitants within these Houses of Law with the aim to reduce inequalities between the citizens who can hire private lawyers and the ones who cannot. First, this research examines the means by which the French Government implemented these affirmative action policies, which are an obstacle in the state's pursuit of the principle of equality; a fundamental precept of the French Republic . Instead of focusing on people, governmental policy targeted geographic areas, specifically inner city. Secondly, this research studies the work of private lawyers operating within the public sector judicial structures and asks whether these "Houses of Law" are equitable arrangements for all citizens due to their locational situation.

Introduction: Positron emission tomography (PET) is a high-resolution, sensitive, molecular and functional imaging technique that permits repeated, non invasive assessment and quantification of specific biological and pharmacological processes in humans[1]. In regard to its physical and nuclear characteristics, fluorine-18 appears often as the radionuclide of choice for the preparation of short-lived positron-emitter radiotracers[2]. F-18 labelling reaction of biomolecules such as peptides[3], oligosaccharides, and oligonucleotides[4] (ONs) requires very mild reaction conditions. The method of choice for a highly efficient fluorine-18-labelling of ONs is today the conjugation of a prosthetic group, carrying the radioisotope, with a reactive function of the ONs. Methods: For the ligation reaction of the prosthetic group with the ONs, we selected click reaction and more particularly the CuI catalyzed formation of 1,2,3-triazole using Huisgen 1,3-dipolar cycloaddition of terminal alkynes with azides. This reaction is highly regioselective leading to 1,4-disubstituted 1,2,3-triazoles and can be performed in different solvents with very high yield[5-7]. Conjugations with ONs are usually performed at 3’-ends using a well chosen linker in order to limit degradation by exonucleases[8]. Here we report the synthesis of an alkyne-bearing linker which can be attached at 3’-ends to any sequence of ONs. Results: The linker was prepared in two steps by reaction of commercially available (R)-(+)--hydroxy--butyrolactone with propargylamine followed by protection of the primary hydroxyl with the 4,4’-dimethoxytrityl group[9]. The second step is the reaction with succinic anhydride to obtain a carboxylic function which can be attached to the Amino-SynBase CPG. The resin load was 80 µmol/g. Conclusions: We have prepared a new universal linker which allows introducing an alkyne function at the 3’-end of ONs. This alkyne modified ONs can then react under click conditions with an azide function of a prosthetic group carrying the fluorine radioisotope. As prosthetic group, we selected the 1-azido-4-(3-[18F]fluoropropoxy)benzene which is fully automated produce in our lab[10]. The further results of radiosynthesis of this prosthetic group and the results of click reactions will be presented.

Au cours de cette expérience, aucune modification du poids corporel ou de la cholestérolémie n’a été observée. Par contre, le traitement des animaux par le BM-573, a eu pour effet de diminuer les lésions athéromateuses de manière significative tandis que l’aspirine a été sans effet sur ce paramètre. Ces données ont été confirmées par des analyses histopathologiques et biochimiques. Ces résultats confirment que l'antagonisme sélectif des récepteurs TP associé à une inhibition de la thromboxane synthétase réduit significativement les lésions athéromateuses chez les souris apo E-/-.

La question de l’abaissement du droit de vote à 16 ans a toujours fait l’objet de débats dans certains cercles universitaires. Lors des dernières élections autrichiennes, les jeunes de 16 ans et plus ont été invités à voter même si les jeunes eux-mêmes sont souvent partagés, voire hostiles à l’idée. Or, une question comme le droit de vote à 16 ans, peu discutée publiquement et engageant plusieurs dimensions de la vie d’un individu, n’est-elle pas une question de débat idéale, où la confrontation des idées peut amener à modifier les points de vue et révéler – et même modifier – les attitudes plus globales des jeunes envers l’intérêt politique et la participation ? Partant d’un sondage aléatoire auprès des 15-21 ans en Belgique francophone, un sous-échantillon de 400 jeunes sera retenu pour discuter du vote à 16 ans, de l’intérêt et de leur participation politique lors d’une journée avec 5 experts. Le sondage initial sera redistribué pour mesurer l’impact de la discussion et des entretiens approfondis seront menés avec un sous-groupe pour étudier les mécanismes de socialisation politique. Ces premiers résultats sont présentés. [less ▲]

Recently, authors have emphasized the differences between brand images held by different individuals depending on the perception, the experience with the brand and the types of contacts with the company. This finding is in sharp contrast with the conventional view recommending consistency and coherence in all the company’s actions. This research tradition has been called the consumer-focused view. Therefore, the author emphasized several academic motivations to develop research on brand image measurement on a consumer level. First, considering that different images are socially constructed constellations of meanings, established between marketers and consumers, with implications for both parties as well as for the marketplace and society at large, this phenomenon raises new issues in managing brand image: Should the company define segments with different brand perceptions and adapt its strategy to these perceptions, how can the city council satisfy the different stakeholders of a city brand, to what extent does the launch of a junior brand influence the perception of a senior brand with a similar name, to what extent do opinion leaders and antibrand activists influence the perception of a corporate brand. Second, there is a need for a process-oriented methodology, namely one that recognizes changes in brand images due to all the influences in the marketplace, to measure the brand perception and capture any change in the brand perception that is due to external factors, namely factors that are not decided by the company. Third, considering the link between brand image and brand equity, the method should focus on the contribution of attributes to brand equity, capturing the strengths, uniqueness and the favourability of these associations. And fourth, regarding the varied natures of brand attributes (functional, emotional, people, ethics, etc) depending on the type of brand (product brand, service brand, city brand and corporate brand), this technique to assess brand image perception should be applicable to all kinds of brands. As a result, the overall objective of this research is to provide profound insight into a measurement method of brand image perception and changes in brand image perception, capturing the strengths, uniqueness and favorability of brand attributes in different contexts, as a consequence of the new consumer focused and process-oriented views.

Introduction. Recent data showed that subchondral bone plays an important role in osteoarthritis (OA). Metabolic and morphologic modifications in this tissue contribute to the degradation of the overlaying cartilage. It was suggested that abnormal mechanical pressure exerted onto the articulation was responsible to these changes. Here, we evaluated the effects of compression on osteoblasts from subchondral bone. Method. Osteoblasts were isolated from sclerotic (SC) or non-sclerotic (NSC) areas of human OA subchondral bone. After 28 days, osteoblasts were surrounded by their matrix. This osteoblasts-containing membrane was then placed onto a Biopress Flexercell plate and submitted to a 4h 1.67 MPa compression (1 Hz). Expression of IL-6, IL-8, COX-2, VEGF, IGF-1, OPG and RANKL was evaluated by RT-PCR. IL-6, IL-8 and PGE2 were quantified by ELISA. Results. Basal IL-6, VEGF, COX-2, IGF-1 and RANKL mRNA levels were significantly increased in SC osteoblasts as compared to NSC. By contrast, SC osteoblasts expressed less OPG than those from NSC areas. Compressions induced the expression of genes coding for IL-6, IL-8, COX-2, IGF-1, VEGF and RANKL but decreased the expression of OPG in NSC osteoblasts (p<0.01). Interestingly, compressed NSC osteoblasts expressed similar levels of these genes than SC osteoblasts. Conclusions. We show that our model of compression can induce in NSC osteoblasts a phenotype similar to this observed in sclerotic areas. Moreover, SC osteoblasts are less sensitive to mechanical stimuli than NSC osteoblasts. These results clarify the role of compression in the pathogenesis of subchondral bone sclerosis and allow new perspectives of research in this field. [less ▲]

In spite of diasporic subjectivity being recurrently conceptualised through a rhetoric of “fluidity,” “multiple affiliations” and “national non-attachment,” today’s literature of the Indian diaspora reveals that the “un-transnational” ideology of the return is still running deep in the first and second-generation migrant imaginary. Vijay Mishra’s recent attempt to explore the idea of “writing diaspora” in an analogy with writing trauma or writing mourning is illuminating in this respect, because it constitutes a theoretical framework able to bear witness to the maintenance of a diasporic imaginary structured by the loss of the Motherland, whether this loss involves firsthand experience of migration or originates from a “phantom loss” refigured by the second generation. Drawing on Mishra’s theorizing of the diasporic imaginary, my paper will explore Jhumpa Lahiri’s representation of the second generation’s “inheritance of loss” in “Once in a Lifetime,” the short-story opening Unaccustomed Earth’s trilogy. By narrating Hema’s and Kaushik’s parallel journey from childhood to early adulthood, Lahiri rewrites the notion of return as melancholic attachments through which the unsymbolizable gap left by the absence of the Motherland can be represented, renegotiated and perhaps then, put to rest. In my paper, I wish to show that not only does Lahiri use melancholy as a means of representing second-generation subjectivities haunted by impossible mourning and unclaimed legacies, but also that she rehabilitates the notion of return as a way of envisaging a diasporic future that is swarming with ghosts. In that sense, Lahiri illustrates that the notion of homeland and the trope of the return can also be associated with a promise of futurity. [less ▲]

Purpose: To determine the profile of Coll2-1, Coll2-1NO2 and myeloperoxydase (MPO) serum concentrations in experimental knee OA induced in the dog by transection of the anterior cruciate ligament. Methods: Surgical transection of the ACL of the right knee was performed on 16 adult crossbred dogs. The dogs were sacrificed 8 weeks after the surgical procedure. Coll2-1, Coll2-1NO2 and MPO were measured by specific immunoassays in 16 dogs at baseline and every 2 weeks during the 8 weeks. The results were expressed as median (range). Results: Immunostainings with D3 and D37, the antiserum recognizing Coll2-1 and Coll2-1NO2, respectively, labelled extracellular matrix in the superficial layer of fibrillated cartilage. After the transection of the ACL, the concentration of 3 biomarkers increased significantly (Friedman test: p<0.001). The concentrations of Coll2-1 and MPO were significantly increased at week 2 compared to baseline [Coll2-1 baseline: 281.57 (131.02-384.67) nM vs Coll2-1 week 2: 345.52 (181.15-589.25) nM (p<0.01) and MPO baseline: 5.16 (<0.4-14.7) ng/ml vs MPO week 2: 14.54 (3.28-31.50) ng/ml (p<0.001)] and remained stable until week 8 [Coll2-1 week 8:318.89 (117.95-492.28) nM and MPO week 8: 11.55 (2.87-42.94) ng/ml]. The Coll2-1NO2 concentration increased significantly at weeks 6 and 8 compared to baseline [Coll2-1NO2 baseline: 0.54 (0.29-1.48) nM vs Coll2-1NO2 week 6: 0.64 (0.40-1.9) nM (p<0.001) vs week 8: 0.61 (0.37-1.79) nM]. Conclusions: These findings suggest that Coll2-1 is a relevant marker for the detection of early structural changes in OA dogs. Interestingly, MPO and Coll2-1NO2 are increased in OA dogs indicating that an oxidative stress occurs in this OA model. [less ▲]
