International sport governing bodies (ISGBs) are built on the foundations of freedom of association and traditionally enjoy a large degree of autonomy in their decision-making. Their autonomy is increasingly confined, however, and their hierarchical self-governance is giving way to a more networked governance, in which different stakeholders exert power in different ways and in different contexts in a complex web of interrelationships. Taking a rationalist perspective on the autonomy of ISGBs, this article demonstrates that ISGBs are deploying strategies to safeguard their waning governing monopoly over international sport. Opting for an inductive approach, the authors present four possible conceptualizations of autonomy as applied to ISGBs, namely political autonomy, legal autonomy, financial autonomy and pyramidal autonomy. For each dimension, they describe the different strategies ISGBs wield in order to safeguard different dimensions of their autonomy. This article uses governance theories to hypothesize that the autonomy of ISGBs can be understood as 'pragmatic autonomy' since ISGBs only cede certain aspects of their autonomy under particular circumstances and when being subject to specific threats. Acting in a rationalist manner, they are able to keep control over governance developments in sport by using indirect and more subtle forms of governance.

Los grandes eventos deportivos se han utilizado con fines promocionales para los territorios desde el siglo XIX. En este sentido, la Copa del Mundo de la FIFA de 2022, que se celebrará en Qatar, deviene una excusa ideal para el gobierno de la nación para legitimar su posicionamiento internacional, así como para participar activamente en el negocio mundial del fútbol. Además, desde 2011, Qatar Foundation (QF) ejecuta un acuerdo de patrocinio con el FC Barcelona, último campeón de la UEFA Champions League (ECL) y del Mundial de Clubes de la FIFA (2011), que le permitirá desarrollar proyectos sociales vinculados a la marca Barça en todo el mundo. Este artículo tiene el objetivo de analizar el posicionamiento internacional de Qatar, canalizado mediante un proceso de construcción de marca protagonizado por el deporte y proyectado a través de los medios de comunicación qataríes (AlJazzera) y los propios de los territorios donde el gobierno qatarí invierte, como es el caso de Cataluña.

Cet article a pour but d'identifier et de mieux comprendre les liens entre les motivations des pratiquantes de sports de remise en forme, les troubles du comportement alimentaire (TCA) et les troubles psychologiques associés (i.e., insatisfaction corporelle, dépendance à l'exercice physique). Au total, 1270 pratiquantes ont répondu à un questionnaire et 40 ont participé à un entretien semi-directif. Les motivations de perte de poids et/ou modification de l'apparence corporelle sont en lien avec les TCA et l'insatisfaction corporelle. La dépendance à l'exercice physique n'est pas systématique chez les femmes avec TCA. Les pratiquantes de sports de remise en forme motivées uniquement par la perte de poids et/ou la modification de l'apparence sont plus à risques dans levdéveloppement des TCA. The aim of this study was to identify and to better understand links between females' motives in fitness sports, eating disorders (ED) and associated psychological disorders (i.e. body dissatisfaction, exercise dependence). In all, 1270 women were asked by questionnaire and 40 by semi-structured interview. Weight loss/body appearance change motives are related to ED and body dissatisfaction. Exercise dependence are not systematic in women with ED. Fitness sports are at risk in the development of ED for women motivated only by weight loss/body appearance change motives

BACKGROUND AND PURPOSE Kyotorphin (KTP; L-Tyr-L-Arg), an endogenous neuropeptide, is potently analgesic when delivered directly to the central nervous system. Its weak analgesic effects after systemic administration have been explained by inability to cross the blood-brain barrier (BBB) and detract from the possible clinical use of KTP as an analgesic. In this study, we aimed to increase the lipophilicity of KTP by amidation and to evaluate the analgesic efficacy of a new KTP derivative (KTP-amide - KTP-NH 2). EXPERIMENTAL APPROACH We synthesized KTP-NH 2. This peptide was given systemically to assess its ability to cross the BBB. A wide range of pain models, including acute, sustained and chronic inflammatory and neuropathic pain, were used to characterize analgesic efficacies of KTP-NH 2. Binding to opioid receptors and toxicity were also measured. KEY RESULTS KTP-NH 2, unlike its precursor KTP, was lipophilic and highly analgesic following systemic administration in several acute and chronic pain models, without inducing toxic effects or affecting motor responses and blood pressure. Binding to opioid receptors was minimal. KTP-NH 2 inhibited nociceptive responses of spinal neurons. Its analgesic effects were prevented by intrathecal or i.p. administration of naloxone. CONCLUSIONS AND IMPLICATIONS Amidation allowed KTP to show good analgesic ability after systemic delivery in acute and chronic pain models. The indirect opioid-mediated actions of KTP-NH 2 may explain why this compound retained its analgesic effects although the usual side effects of opioids were absent, which is a desired feature in next-generation pain medications

Fibrinolytic therapy with Recombinant Tissue-Plasminogen Activator (rt-PA) is currently the only effective treatment for ischaemic stroke in its acute phase. Even though its use generally improves the prognosis of those patients likely to receive it, rt-PA administration is associated to several risks, such as haemorrhagic transformation ofthe ischaemic lesion and activation of excitotoxic mechanisms that may contribute to an increase in mortality or to a poor outcome in certain occasions, specially when arterial recanalization is not achieved or the rt-PA is lately administrated. Since in the last few years the role of glutamate in the neurotoxicity associated toischaemia has been widely studied and it is known that high plasma glutamate levels are predictors of ischaemic lesion growth and poor neurological outcome, it is necessary to find out which factors can contribute to glutamate release in the brain. The aim of this study is to determine if rt-PA administration is related to an increase in plasma glutamate levels, as well as to define if higher plasma glutamate levels at admission are related to different evolution and prognosis of our patients, both in those in which recanalisation is achieved and not. A series of cases of patients with hemispheric cerebral infarction admitted in our hospital during a year will be studied, and the data obtained from them will be compared to the data obtained from a control group, the samples of wich were takenyears ago, before rt-PA was routinely used
