The senses of the "Ren" : ethnography of a Tai-chi school

Dans une première partie, une approche sociohistorique permet de dénaturaliser les catégories d'arts martiaux et de sports de combat forgées par des acteurs sociaux en lutte pour le contrôle d’un champ. Cette première étape permet d'identifier trois idéaux types : les combats codifiés, les combats culturalisés et les pratiques de self-defense. La deuxième partie démontre à partir des données de terrains recueillies que le Tai-chi peut être analysé comme une technique de soi et l’école de Tai-chi comme un dispositif visant à l’incorporation d’un éthos confucéen par les élèves. La troisième partie montre la subjectivation des élèves repose sur l’incorporation d’une culture kinesthésique. Cependant, les élèves transforment le dispositif d’éthopoïèse confucéen du maître en un dispositif d’exopoïèse. Le « Ren », forme idéalisée du lien social confucéen, devient une forme de non-lien social permettant d’enraciner l’école dans un imaginaire exotique. L’école devient ainsi un espace d'altérité radicale permettant un déplacement récréatif, une sublimation du quotidien. Cet espace devient ainsi un lieu privilégié de réinvention de soi.In the first part of thesis, a socio-historical analysis allows an unnaturalision of the concept of martial arts and combat sport created by social actors in their struggle for controlling a field. This first step enables us to identify three ideal types : the codified combat, culturalised combat and self-defence practice. The second part shows from the field data that Tai-chi could be analysed as a technology of the self and the Tai-chi school as an apparatus aiming at the embodiment of a Confucian ethos by the students. The third part points out that the student subjectivation lies on the embodiment of a kinaesthetic culture. However, the student transforms the Confucianist éthopoïesis apparatus into an exopoïesis apparatus. The « Ren », an idealised form of Confucianist social relations became a form of non-social relations rooting the school in an exotic imaginary. The school thus became a space of radical alterity enabling a recreative shift, a sublimation of everyday life. Thus, the school became a favoured place of self-reinvention

Pharmacy-Based Opportunistic Atrial Fibrillation Screening at a Community Level: A Real-Life Study

Purpose: Opportunistic pharmacy-based screening of atrial fibrillation (AF) appears effective, but the proportion of detected citizens is unknown. The aim of our real-life study was to determine rates of screening in a community population according to age group and gender. Methods: We conducted four community campaigns of pharmacy-based single-time point AF screening that involved individuals ≥65 years. We used a single-lead and hand-held device MyDiagnostick (6229 EV Maastricht, The Netherlands) that generates a 60-s ECG trace. All pharmacies of the communities (n = 54) were involved. Rates of screening were assessed on the base of the French National Institute for Statistics and Economic Studies data and were expressed as percentage and 95% Confidence interval (CI). Results: We screened 4208 individuals (Mean age, 74.2 ± 6.6 years; females, 60.2%). The screening rate in citizens aged ≥65 years was 17.2% (16.6–17.7), and higher in females than in males (17.9% [17.3–18.6] versus 16.0 [15.3–16.8], p p = 0.04), male sex (OR: 4.30 [2.33–7.92], p p = 0.0008) were independent predictors of unknown AF. Conclusion: Single-lead AF detection performed in community pharmacies result in screening one in six elderly citizens. Although male sex and elderly predicted unknown AF diagnosis, they were less involved in such designed campaigns

La supplémentation alimentaire avec un concentré spécifique de melon corrige la dysfonction vasculaire induite par un régime cafétéria

International audienceBackground: Obesity-related metabolic syndrome is associated with high incidence of cardiovascular diseases partially consecutive to vascular dysfunction. Therapeutic strategies consisting of multidisciplinary interventions include nutritional approaches. Benefits of supplementation with a specific melon concentrate, enriched in superoxide dismutase (SOD), have previously been shown on the development of insulin resistance and inflammation in a nutritional hamster model of obesity. Objective: We further investigated arterial function in this animal model of metabolic syndrome and studied the effect of melon concentrate supplementation on arterial contractile activity. Design and results: The study was performed on a hamster model of diet-induced obesity. After a 15-week period of cafeteria diet, animals were supplemented during 4 weeks with a specific melon concentrate (Cucumis melo L.) Contractile responses of isolated aorta to various agonists and antagonists were studied ex vivo. Cafeteria diet induced vascular contractile dysfunction associated with morphological remodeling. Melon concentrate supplementation partially corrected these dysfunctions; reduced morphological alterations ; and improved contractile function, especially by increasing nitric oxide bioavailability and expression of endogenous SOD. Conclusions: Supplementation with the specific melon concentrate improves vascular dysfunction associated with obesity. This beneficial effect may be accounted for by induction of endogenous antioxidant defense. Such an approach in line with nutritional interventions could be a useful strategy to manage metabolic syndromeÁinduced cardiovascular trouble

Respiratory dysfunctions in two rodent models of chronic epilepsy and acute seizures and their link with brainstem serotonin system

Abstract Patients with drug-resistant epilepsy can experience respiratory alterations notably during seizures. The mechanisms underlying this long-term alteration of respiratory function remain unclear. This study aimed at determining in rats whether epilepsy is associated with alterations of both the respiratory function and brainstem serotonin (5-HT) system. Epilepsy was triggered by pilocarpine-induced status epilepticus in rats. 30-50% of epileptic (EPI) rats exhibited sharp decrease of oxygen consumption (SDOC), low metabolic rate of oxygen and slow regular ventilation; these rats were called EPI/SDOC+ rats. These alterations were only detected in rats with chronic epilepsy, independent of behavioral seizures, persisted over the time, and were not associated with death. In these rats, 5-HT fiber density in the nucleus tractus solitarius was below that of control and EPI/SDOC-rats. Both EPI/SDOC+ rats and DBA/2 mice presenting with fatal respiratory arrest following an audiogenic-induced seizure, a model of sudden and expected death in epilepsy, had increased transcript levels of tryptophan hydroxylase 2 (p<0.001 for both strains) and 5-HT presynaptic transporter (rats: p=0.003; mice: p=0.001). Thus, our data support that 5-HT alterations are associated with chronic and acute epilepsy-related respiratory dysfunctions

Respiratory dysfunction in two rodent models of chronic epilepsy and acute seizures and its link with the brainstem serotonin system

International audiencePatients with drug-resistant epilepsy can experience respiratory alterations, notably during seizures. The mechanisms underlying long-term alterations in respiratory function remain unclear. As the brainstem 5-HT system is a prominent modulator of respiratory function, this study aimed at determining whether epilepsy is associated with alterations in both the respiratory function and brainstem serotonin (5-HT) system in rats. Epilepsy was triggered by pilocarpine-induced status epilepticus in rats. Our results showed that 30-50% of epileptic (EPI) rats exhibited a sharp decrease in oxygen consumption (SDOC), low metabolic rate of oxygen, and slow regular ventilation (EPI/SDOC + rats). These alterations were detected only in rats with chronic epilepsy, independent of behavioral seizures, were persistent over time, and not associated with death. In these rats, 5-HT fiber density in the nucleus tractus solitarius was lower than that in the control and EPI/SDOC- rats. Both EPI/SDOC + rats and DBA/2 mice that present with audiogenic-induced seizure followed by fatal respiratory arrest-a model of sudden and expected death in epilepsy-had increased transcript levels of tryptophan hydroxylase 2 and 5-HT presynaptic transporter. Thus, our data support that 5-HT alterations are associated with chronic and acute epilepsy-related respiratory dysfunction
