Objective: To identify the sociodemographic profile and to compare the quality of life of elderly people who practice physical exercises in a group with sedentary elderly.
Methods: This is a cross-sectional study with a quantitative approach, composed of two groups: Group I consisted of 50 elderly people practicing physical exercise in a group; and Group II composed of 50 sedentary elderlies. Data were collected through two questionnaires; one questionnaire focused on the sociodemographic data survey and the SF-36 quality of life questionnaire. The data were analyzed by the BioEstat 5.0 program using the Z-Test.
Results: Group I had better scores in the domains, limitations due to physical aspects and general health, in the other domains, group II had better scores. Factor that can be attributed to the modality of the physical exercise performed by group I that was in the group I and by the form of the allocation of the sample.
Conclusion: The women were mostly in group I, and both groups were comprised of seniors over 61 years old, widowers and retirees. Statistically, only the general state of health showed a significant difference between the two groups.

Abstract
Background: Orthopaedic traction tables are used as an aid in numerous surgical procedures. The present paper aims to present a prototype of an external device of lower limb traction, which is portable, of simple construction, and can be installed on any operating table, with possible application in surgical and teaching practices. We will compare the quality of radiographic images obtained with the help of this prototype (PT) to those images obtained with the aid of the conventional traction table (CT).
Materials and methods: Cross-sectional, observational, and double blind study, approved by the Research Ethics Committee. On two occasions 36 randomly selected radiographs of the lower limbs, 18 of which obtained on the CT and the remaining on the PT, were evaluated by nine physicians. These radiographs were obtained from three volunteer and none of them presented musculoskeletal system disorders previously diagnosed in the study. Examiners rated each picture from 1 to 5, according to the quality of the image obtained. The responses were submitted to statistical analysis by SPSS ®, v23. Comparisons were considered significant when p <0.05, with a 95% confidence interval.
Results: The average ratings were similar and all significance tests between the averages were higher than 0.9. The intra-observer agreement was 76.13% for the PT and 82.69% for the CT. The inter-observer agreement was low for both models. Due to its lower weight and smaller size compared to the CT and the material used for prototyping, the production cost of the PT is quite affordable.
Conclusions: The PT presented in this paper is a good alternative to CT.

Published: March 2017

Abstract
We quantitatively investigated the hydrogen addition reactions of acetylene (C2H2) and ethylene (C2H4) on amorphous solid water (ASW) at 10 and 20 K relevant to the formation of ethane (C2H6) on interstellar icy grains. We found that the ASW surface enhances the reaction rates for C2H2 and C2H4 by approximately a factor of 2 compared to those on the pure-solid C2H2 and C2H4 at 10 K, probably due to an increase in the sticking coefficient and adsorption energy of the H atoms on ASW. In contrast to the previous proposal that the hydrogenation rate of C2H4 is orders of magnitude larger than that of C2H2, the present results show that the difference in hydrogenation rates of C2H2 and C2H4 is only within a factor of 3 on both the surfaces of pure solids and ASW. In addition, we found the small kinetic isotope effect for hydrogenation/deuteration of C2H2 and C2H4 at 10 K, despite the requirement of quantum tunneling. At 20 K, the reaction rate of deuteration becomes even larger than that of hydrogenation. These unusual isotope effects might originate from a slightly larger number density of D atoms than H atoms on ASW at 20 K. The hydrogenation of C2H2 is four times faster than CO hydrogenation and can produce C2H6 efficiently through C2H4 even in the environment of a dark molecular cloud.
Which Stars Are Ionizing the Orion Nebula?

Abstract
The common assumption that

In this paper we establish through comparison of the relative strengths of emission lines with expectations from Cloudy models and through the direction of the bright edges of proplyds that

, which lies beyond the Bright Bar, also plays an important role.

does dominate ionization in the inner part of the Orion Nebula, but outside of the Bright Bar as far as the southeast boundary of the Extended Orion Nebula,

Published: March 2017

Abstract
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the [C ii] fine-structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (

). We also present observations targeting the CO(2–1), CO(7–6), and [C i] 369 μm lines in the same source obtained at the Very Large Array and Plateau de Bure Interferometer. We find a [C ii] line flux of

Jy

and a continuum flux density of

mJy beam−1, consistent with previous unresolved measurements. No other source is detected in continuum or [C ii] emission in the field covered by ALMA (∼ 25″). At the resolution of our ALMA observations (0.″23, or 1.2 kpc, a factor of ∼70 smaller beam area compared to previous measurements), we find that the majority of the emission is very compact: a high fraction (∼80%) of the total line and continuum flux is associated with a region 1–1.5 kpc in diameter. The remaining ∼20% of the emission is distributed over a larger area with radius ≲4 kpc. The [C ii] emission does not exhibit ordered motion on kiloparsec scales: applying the virial theorem yields an upper limit on the dynamical mass of the host galaxy of

, only ∼20 × higher than the central black hole (BH). The other targeted lines (CO(2–1), CO(7–6), and [C i]) are not detected, but the limits of the line ratios with respect to the [C ii] emission imply that the heating in the quasar host is dominated by star formation, and not by the accreting BH. The star formation rate (SFR) implied by the FIR continuum is 105–340

, with a resulting SFR surface density of ∼100–350

kpc−2, well below the value for Eddington-accretion-limited star formation.

Background Vitamin D, a potent immune-modulator, has been linked to the pathogenesis of chronic hepatitis B (CHB). This study was aimed at investigating the association between single nucleotide polymorphisms (SNPs) in vitamin-D-related genes and treatment response to pegylated interferon (PEG-IFN) in patients with CHB. Methods A total of 275 Thai patients (122 hepatitis B e antigen [HBeAg]-positive and 153 HBeAg-negative CHB) treated with 48-week PEG-IFN were recruited. Virological response (VR) at 48 weeks post-treatment was defined as HBeAg seroconversion plus HBV DNA <2,000 IU/ml for HBeAg-positive CHB and HBV DNA <2,000 IU/ml for HBeAg-negative CHB. The SNPs VDR (rs2228570), DBP (rs7041) and CYP27B1 (rs4646536) were analysed. Results The distribution of TT, CT and CC genotypes of rs4646536 in this cohort was 21.8%, 46.2% and 32.0%, respectively. There was no difference in its distribution according to HBeAg status. In HBeAg-positive CHB, patients with TT genotype, compared with non-TT genotype, achieved higher VR (53.3% versus 31.5%; P=0.032) and hepatitis B surface antigen (HBsAg) clearance (20.0% versus 5.4%; P=0.016). In HBeAg-negative CHB, the corresponding figures were 60.0% versus 30.9% ( P=0.003) and 16.7% versus 5.7% ( P=0.045), respectively. Patients with TT genotype had more rapid HBsAg decline than those with non-TT genotype. However, SNPs rs2228570 and rs7041were not associated with VR and HBsAg clearance. Logistic regression analysis demonstrated that SNP rs4646536 and baseline HBsAg level were independent predictors of VR in both HBeAg-positive and HBeAg-neg-ative CHB. Conclusions Our data suggest that SNP rs4646536 in the CYP27B1 gene is a predictive factor of response to PEG-IFN therapy in Thai patients with CHB.
Crise de l’Union européenne ou crises de la démocratie ?

Les institutions européennes sont régulièrement mises en cause pour leur déficit démocratique. Pourtant, depuis les années 1990, les traités successifs ont instauré différents instruments permettant de pallier ce déficit. Aujourd’hui, la crise de l’Union européenne est sans doute plus profonde et dépasse la question du fonctionnement des institutions. Elle touche la confiance même qu’ont les citoyens dans le projet d’intégration et dans la démocratie.

Les régimes d’Europe centrale tentés par l’autoritarisme et le souverainisme s’appuient sur le retour à un passé mythique, qui s’articule paradoxalement à une reprise de certaines pratiques des temps communistes. D’autres dimensions caractérisent leur glissement hors de l’état de droit démocratique : rapport aux médias, à l’opposition… Ces régimes vont à l’impasse. Seules les sociétés civiles et l’Union européenne peuvent s’opposer à une dynamique dangereuse bien au-delà de ces pays.

Les tentations protectionnistes de la nouvelle administration américaine doivent être prises au sérieux. L’Europe a tout intérêt à préserver les acquis du multilatéralisme commercial, en particulier via une adaptation des pratiques de l’OMC : concevoir des accords économiques globaux et inclusifs, garantir l’équilibre des normes et la gouvernance des accords conclus. Pour cela, l’Europe doit gagner en efficacité institutionnelle et en cohésion politique, bref reprendre l’initiative.

Commerce vertical et propagation des chocs de prix

Published: March 2017

La décomposition des chaînes de valeur internationales est un aspect important de la mondialisation. Partant d’une hypothèse d’inflation par les coûts, nous examinons la propagation des chocs d’offre sur les prix à partir des tableaux Input-Output mondiaux. Le modèle de Leontief adapté dans le cadre d’une économie monde nous permet d’analyser empiriquement l’impact de chocs de change et de productivité sur la zone euro et sur le reste du monde lorsque ces chocs émanent de la zone euro. Nous montrons que la diffusion des chocs opère principalement au premier tour et dépend de la part des inputs importés dans la production ou les exportations. En outre, les chocs de change sont en partie compensés par une modification des prix des inputs ce qui, en cas d’appréciation, limite la perte de compétitivité. L’ampleur de cette compensation n’est pas négligeable et elle est d’autant plus élevée que les pays de la zone euro sont ouverts. Elle est ainsi plus forte pour l’Allemagne (avec une élasticité des prix d’exportation à un choc de l’euro de -9 %) que pour la France (-8 %). L’impact des chocs de productivité est plus important que celui des chocs de change en raison d’un effet de résonance domestique avant leur diffusion internationale. Parmi les grands pays, l’Allemagne est celui qui bénéficie le plus des chocs positifs de productivité émanant des PECO hors zone euro : dans ce cas, l’élasticité de ses prix d’exportation est de 6 % contre 2,5 % pour la France.
L’arbitrage entre le salariat et le travail indépendant au prisme des théories de la firme
Authors: Baudry Bernard , Chassagnon Virgile 
Published: March 2017

Cet article s’intéresse à une nouvelle forme d’organisation du travail, le crowdworking . Cette expression désigne le travail réalisé à partir de plateformes en ligne qui permettent à des individus d’accéder ( via internet) à des organisations (ou à des individus) pour résoudre des problèmes spécifiques et offrir des produits et des services en échange d’une rémunération. Notre problématique consiste à s’interroger sur le potentiel de développement de cette pratique et à repérer les enjeux que le crowdworking met en exergue pour l’analyse économique. Pour ce faire, nous analysons la question de l’arbitrage entre le salariat et le travail indépendant au prisme des grandes théories de la firme en distinguant deux catégories de plateformes, celles qui font appel à du travail peu qualifié et celles qui mobilisent du travail qualifié. Nous montrons que la théorie économique permet de dégager trois variables de cet arbitrage : la nature des actifs humains engagés, la séparabilité des tâches, et la nature des connaissances. L’étude de ces trois variables donne à voir une dynamique d’organisation du travail qui devrait, en principe, rester favorable au salariat donc à l’entreprise.

AbstractLeishmaniases are diseases caused by several Leishmania species. Leishmania (Viannia) braziliensis can cause localized cutaneous leishmaniasis (LCL), which heals spontaneously, or mucosal leishmaniasis (ML), characterized by chronic and intense inflammation and scanty parasitism. Annexin A1 (AnxA1) is a protein involved in modulation and resolution of inflammation through multiple mechanisms. In the present study, the role of AnxA1 was investigated in L. braziliensis–infected BALB/c mice. AnxA1 levels increased at the peak of tissue lesion and parasitism in infected mice. AnxA1 increased also after L. braziliensis infection of BALB/c (wild-type [WT]) bone marrow derived macrophages. Despite a lower parasite intake, parasite burden in bone marrow-derived macrophages from AnxA1−/− mice was similar to WT and associated with an early increase of TNF-α and, later, of IL-10. AnxA1−/− mice controlled tissue parasitism similarly to WT animals, but they developed significantly larger lesions at later stages of infection, with a more pronounced inflammatory infiltrate and increased specific production of IFN-γ, IL-4, and IL-10. AnxA1−/− mice also presented higher phosphorylation levels of ERK-1/2 and p65/RelA (NF-κB) and inducible NO synthase expression, suggesting that AnxA1 may be involved in modulation of inflammation in this model of experimental leishmaniasis. Finally, assessment of AnxA1 levels in sera from patients with LCL or ML revealed that ML patients had higher levels of serum AnxA1 than did LCL patients or control subjects. Collectively, these data indicate that AnxA1 is actively expressed during L. braziliensis infection. In the absence of AnxA1, mice are fully able to control parasite replication, but they present more intense inflammatory responses and delayed ability to resolve their lesion size.
Predicting Manual Therapy Treatment Success in Patients With Chronic Ankle Instability: Improving Self-Reported Function
Authors: Wikstrom Erik A. , McKeon Patrick O. 
Published: March 2017

Context:
Therapeutic modalities that stimulate sensory receptors around the foot-ankle complex improve chronic ankle instability (CAI)–associated impairments. However, not all patients have equal responses to these modalities. Identifying predictors of treatment success could improve clinician efficiency when treating patients with CAI.

Objective:
To conduct a response analysis on existing data to identify predictors of improved self-reported function in patients with CAI.

Design:
Secondary analysis of a randomized controlled clinical trial.

Setting:
Sports medicine research laboratories.

Patients or Other Participants:
Fifty-nine patients with CAI, which was defined in accordance with the International Ankle Consortium recommendations.

Intervention(s):
Participants were randomized into 3 treatment groups (plantar massage [PM], ankle-joint mobilization [AJM], or calf stretching [CS]) that received six 5-minute treatments over 2 weeks.

Main Outcome Measure(s):
Treatment success, defined as a patient exceeding the minimally clinically important difference of the Foot and Ankle Ability Measure–Sport (FAAM–S).

Results:
Patients with ≤5 recurrent sprains and ≤82.73% on the Foot and Ankle Ability Measure had a 98% probability of having a meaningful FAAM–S improvement after AJM. As well, ≥5 balance errors demonstrated 98% probability of meaningful FAAM–S improvements from AJM. Patients &lt;22 years old and with ≤9.9 cm of dorsiflexion had a 99% probability of a meaningful FAAM–S improvement after PM. Also, those who made ≥2 single-limb–stance errors had a 98% probability of a meaningful FAAM–S improvement from PM. Patients with ≤53.1% on the FAAM–S had an 83% probability of a meaningful FAAM–S improvement after CS.

Conclusions:
Each sensory-targeted ankle-rehabilitation strategy resulted in a unique combination of predictors of success for patients with CAI. Specific indicators of success with AJM were deficits in self-reported function, single-limb balance, and &lt;5 previous sprains. Age, weight-bearing–dorsiflexion restrictions, and single-limb balance deficits identified patients with CAI who will respond well to PM. Assessing self-reported sport-related function can identify CAI patients who will respond positively to CS.
