Gallery excavation in clayey rocks induces stress perturbations that trigger damage propagation. The excavation process creates then the so-called excavation damaged zone in which properties are modified. The prediction of the extension and especially of the fracturing structure in this zone remains a crucial issue in the context of underground storage. Since strain localization in shear band mode is frequently observed in experimental works, the excavation damaged zone can be modeled by considering the development of strain localization bands. A hydro-mechanical modelling of a gallery excavation is performed. The numerical results exhibit an excavation damaged zone extension similar to the in situ measurements and provides information about the rock state within this zone. [less ▲]

Nowadays Chemist are request to construct more and more complex architectures bearing multifunctionalities enable to respond to external stimuli. The construction of such complex architectures will be addressed through strong interplay in chemical science, as proposed recently with the concept of integrative Chemistry.[1] We synthesized PVA/ZnO-nanorods composite fibers using co-axial flux extrusion.[2] These fibers exhibit higher anisotropic photonic properties, both in absorption and emission, as a result of the collective alignment of the ZnO nanorods along the main axis of the PVA fiber. This photonic anisotropy is triggered by a synergistic interaction between the PVA matrix, stretched above Tg, and cooled down under strain. Compared with non-elongated fibers that present an isotropic emission, composite fibers previously submitted to a tensile stress absorb selectively UV emission when the polarized laser beam is parallel to the main axis of the fiber. In addition, their photolumincescence is also anisotropic, with a waveguide behavior along the main axis of the fiber. Mechanical properties of these composite fibers are also drastically improved, compared with pure PVA fibers: the longitudinal Young modulus of these fibers is increased from 2 to 6 GPa upon ZnO addition, a value similar to those already observed for composite fibers, prepared either with carbon nanotubes, or Vanadium Oxide macroscopic fibers.

BACKGROUND: The recent evaluation of the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation for estimating the glomerular filtration rate (GFR) in multiple ethnicities has raised the question on how well this equation performs for African-American and Asian subjects. There is no doubt that serum creatinine (Scr) concentration differs between ethnicities and sexes. We show that creatinine-based equations for white populations may be inaccurate for estimating GFR in other ethnic/gender groups, especially in populations from Asia. METHODS: This study presents a mathematical analysis of the CKD-EPI-equation complemented with a literature review of median and reference values for IDMS-standardized Scr-concentrations for multiple ethnicities. RESULTS: The study shows that at equal eGFR-CKD-EPI-values, the ratio of Scr between females and males equals 0.79 and between other ethnicities/sexes and white males is constant too. From this information, it is possible to calculate mean Scr-values that correspond very well with literature values directly obtained from Scr-distributions in healthy white males and females and in black males, but the discrepancy is larger for other populations. CONCLUSIONS: Our results confirm the criticism that has been raised for using the CKD-EPI-equation for these ethnicities. An alternative eGFR-model is proposed based on a population-normalized Scr that needs further validation. [less ▲]

The submarine part of the North Anatolian Fault (NAF) is a very significant hazard for the 12 million people living in Istanbul (Turkey). An accurate seismic risk assessment necessitates paleoseismological data, which can be retrieved in the Marmara Sea by using sedimentary cores. We present here a record of turbidites obtained in cores spanning the Tekirdag ̆ Basin, the Western High, the Central Basin, and the Cinarcik Basin. In the Tekirdag and Western High the turbidites are synchronous pointing to shaking by earthquakes as a triggering mechanism. Generally seismoturbidites in the Marmara Sea are distinguished from other turbidites based in their large extension, their particular granulometric and their particular geochemical characteristics. The 210Pb and 137Cs radionucleides measurements have also shown that the M=7.4 1912 Mürefte earthquake and the M=7.3 1894 Prince's Island earthquake have left a distinctive sedimentary imprint at the top of the studied cores. The chronology of other seismoturbidites is built combining radiocarbon dating and secular variation patterns of paleo-declination and paleo-inclination. Finally the obtained record is compared to the historical seismicity record. [less ▲]

Introduction : Le projet TADAM, une étude contrôlée randomisée, comparait un nouveau traitement assisté par héroïne avec des traitements existants par méthadone à Liège, en Belgique. Nous avons réalisé une étude qualitative sur l'attitude des personnes dépendantes de l'héroïne envers ce type de projet, ainsi que sur l'attitude des intervenants d'institutions de soins travaillant avec ces personnes Méthode : Avant qu'un patient ne soit inclus dans le projet TADAM, il lui était demandé d'expliquer pourquoi il souhaitait rentrer en traitement (n=80). Des interviews ont également été réalisées auprès de consommateurs d'héroïne non inclus dans le projet, avant la période d'inclusion (n=65), au milieu de celle-ci (n=30) et dans ses derniers mois (n=23). Pendant le projet, des interviews ont également été réalisées auprès d'intervenants travaillant dans des institutions de soins pour personnes dépendantes de substances, soit de manière individuelle (n=10), soit en groupe (n=6) pour connaître leur attitude face au projet TADAM. Résultats : De nombreux patients souhaitaient rentrer dans ce projet pour améliorer leurs conditions de vie. La raison principale de ne pas rentrer dans ce type de traitement était la peur de devenir plus dépendant. Cette raison était renforcée par le fait que le traitement par héroïne proposé ne durait que 12 mois et les patients s'inquiétaient de leur situation après ce traitement : ils avaient peur d'être plus dépendants et donc dans une situation plus difficile qu'avant le traitement. L'attitude des intervenants étaient plutôt favorable mais prudente. Conclusion : Contrairement aux craintes préalables, les usagers d'héroïne ne se précipitent pas en masse et sans réfléchir vers un traitement assisté par héroïne. Certains réfléchissent longtemps avant de s'y engager. Une information précise et un traitement sans durée minimum sont nécessaires. [less ▲]

Introduction : Le plasma riche en plaquettes (PRP) aurait des effets bénéfiques sur les symptômes des tendinopathies grâce à la libération locale de leurs nombreux facteurs de croissance. Le but de cette étude est d’évaluer les résultats d’une injection de PRP sur la symptomatologie des patients présentant une tendinopathie patellaire supérieure. Matériels et Méthodes : Vingt patients atteints d’une tendinopathie patellaire supérieure, rebelle aux traitements conservateurs classiques depuis au moins 3 mois, ont bénéficié d’une évaluation du statut algo-fonctionnel (EVA, algomètre de pression, VISA-P et IKDC) et des performances physqiues (isocinétique et optojump), ainsi que d’un bilan d’imagerie (échographie et IRM). Ces analyses ont été réalisées en pré-injection ainsi qu’aux 6èmeet 12èmesemaines post-injection. Le test isocinétique évaluait la force des quadriceps et des ischios-jambiers des deux membres suivant différentes modalités (C60°/sec, C240°/sec et E30°/sec). Le test Optojump évaluait la détente et la puissance musculaire par la mesure de la hauteur de saut via deux modalités («Counter Movement Jump » et « Drop Jump »). Le PRP est obtenue à l’aide d’une machine d’aphérèse (COM.TEC, Fresenius-Kabi), permettant d’obtenir une concentration plaquettaire reproductible d’un patient à l’autre, en l’absence quasi totale de globules rouges et blancs. L’infiltration intratendineuse de PRP (6mL) est réalisé à la pointe de la rotule in loco dolenti sans anesthésie locale. Résultats : Les résultats de notre expérimentation démontrent qu’une seule injection locale de PRP accompagnée d’un programme de rééducation excentrique améliore significativement la cicatrisation du tendon patellaire au niveau du score EVA, de l’algomètre de pression, des scores VISA-P et IKDC. Lors du test isocinétique, seuls l’augmentation du MFM des ischios jambiers en C240°/sec, de la différence bilatérale des ischios jambiers en C60°/sec ainsi que de l’EVA en E30°/sec était significative. Les résultats optojump en terme de détente et puissance musculaire ne montrent pas d’amélioration des performances. Néanmoins, l’EVA du « Counter Movement Jump » se voit significativement diminuée après l’infiltration. Enfin, les résultats de l’imagerie (échographie et IRM) ne démontrent pas de modification significative du tendon. Conclusions : L’injection locale de PRP dans le cadre de tendinopathies patellaires supérieure permet une diminution de la symptomatologie douloureuse à 6 semaines, se poursuivant à 12 semaines. La performance fonctionnelle et l’imageries, quant à elles, ne sont pas modifiées. [less ▲]

Aim. The objective of this study was to use in vivo PET/CT imaging as a validation tool for a novel human colorectal carcinoma model being developed in chicken chorioallantoic membrane (CAM). For this initial pilot study a cell line modeling colon cancer was selected and imaged using [18F]fluorodeoxyglucose (FDG). <br />Materials and methods. A window was made in the shell of fertilized chicken eggs and 3x106 SW1222 human colorectal carcinoma cells were implanted at day 10 post-fertilization. On day 17 the shell window was enlarged to allow direct injection of FDG (12.2 ± 4.5 MBq/egg) into a CAM blood vessel. During injection the egg was warmed on a heating pad. A mixture of ketamine/medetomidine (50 :1 mg/ml, 0.2 ml/egg) was injected into the albumin in some eggs to assess the effect of anesthesia. After FDG injection the egg was returned to the incubator for a 45 min uptake period before imaging. Imaging was performed on a Siemens Focus 120 microPET with structural CT on a General Electric eXplore CT120. A Minerve cell system allowed reproducible positioning between modalities. PET data was acquired in list mode before histogramming into a single 10 min frame for reconstruction using a 3D maximum a posteriori (MAP) method with all corrections except scatter. A standard 100 µm (theoretical) image resolution protocol (70 kV, 50 mA, 32 ms, 220 views) was used to obtain structural CT data. Image coregistration was performed in PMOD version 3.3. In a separate egg, the influence of added contrast on the CT data was investigated by adding iodinated contrast agent (Iobitridol 35 mgI/ml) to the albumin. <br />Results. FDG uptake was clear in chick and tumor, with notably high uptake at the major joints. Tumors were identified by localization of FDG uptake on the surface of the CAM. A lack of soft tissue contrast between tumor, CAM and albumin made precise structural identification of the tumor difficult. Anesthesia was crucial to image quality in both PET and CT. CT contrast between the soft tissues of the chick and surrounding albumin/structures was improved by addition of contrast agent. <br />Conclusion. For the first time we demonstrate successful imaging of FDG uptake in a human colorectal carcinoma chicken CAM model in ovo. Methods to improve structural data are under investigation and will be used in further studies. With such improvement, this model could be of great value to PET oncology imaging. [less ▲]

La diplomacia pública es una actividad de comunicación política internacional en cuya práctica destaca Estados Unidos por ser el país donde primero se desarrolla e institucionaliza. Después del decaimiento posterior a la Guerra Fría, la diplomacia pública de este país experimentó una renovada importancia tras los atentados del 11-S. La "guerra contra el terror" promovida por la Administración Bush se acompañó de estrategias de diplomacia pública diseñadas para lograr apoyos a la lucha contra el terrorismo y disminuir los niveles de antiamericanismo. En este libro se ofrece un marco que recoge los aspectos teóricos más relevantes en el estudio de la diplomacia pública, para posteriormente ofrecer una visión histórica de la diplomacia pública estadounidense y la "guerra contra el terror". Además, se propone un modelo de análisis para la diplomacia mediática y se aplica al discurso de George W. Bush. [less ▲]

Respiratory syncytial virus (RSV), a prominent cause of airway morbidity in children, maintains an excessive hospitalization rate despite decades of research. Host factors are assumed to influence the disease severity. As a first step toward identifying the underlying resistance mechanisms, we recently showed that inbred mouse strains differ dramatically as regards their susceptibility to pneumonia virus of mice (PVM), the murine counterpart of RSV. PVM infection in mice has been shown to faithfully mimic the severe RSV disease in human infants. This study aimed at dissecting the remarkable PVM-resistance shown by the SJL/J strain. To characterize its genetic component, we assessed clinical, physiopathological, and virological resistance/susceptibility traits in large first (F1) and second (F2) generations obtained by crossing the SJL/J (resistant) and 129/Sv (susceptible) strains. Then, to acquire conclusive in vivo evidence in support of the hypothesis that certain radiosensitive hematopoietic cells might play a significant role in PVM-resistance, we monitored the same resistance/susceptibility traits in mock- and γ-irradiated SJL/J mice. Segregation analysis showed that (i) PVM-resistance is polygenic, (ii) the resistance alleles are recessive, and (iii) all resistance-encoding alleles are concentrated in SJL/J. Furthermore, there was no alteration of SJL/J PVM resistance after immunosuppression by γ-irradiation, which suggests that adaptive immunity is not involved. We conclude that host resistance to pneumoviruses should be amenable to genetic dissection in this mouse model and that radioresistant lung epithelial cells and/or alveolar macrophages may control the clinical severity of pneumovirus-associated lung disease.

This paper is the first of a series considering the properties of distribution of nearby galaxies in the low density regions. Among 7596 galaxies with radial velocities V_{LG}<3500 km/s, absolute magnitudes M_K<-18.4^m$, and Galactic latitudes |b| >15 degr there are 3168 field galaxies (i.e. 42%) that do not belong to pairs, groups or clusters in the Local universe. Applying to this sample the percolation method with a radius of r_0=2.8 Mpc, we found 226 diffuse agglomerates with n>=4 number of members. The structures of eight most populated objects among them (n>=25) are discussed. These non-virialized agglomerates are characterized by a median dispersion of radial velocities of about 170 km/s, the linear size of around 6 Mpc, integral K-band luminosity of 3*10^{11} L_sun, and a formal virial-mass-to-luminosity ratio of about 700 M_sun/L_sun. The mean density contrast for the considered agglomerates is only <Delta n/\bar{n}\gtrsim 5, and their crossing time is about 30-40 Gyr. [less ▲]
