L'inhibition de la production d'AMPc est modulée différemment à court et long terme par l'internalisation du récepteur opioïde delta

Les opioïdes sont les analgésiques les plus puissants mais leur utilisation prolongée peut entraîner le développement d’une tolérance analgésique. La tolérance serait en partie associée à l’inhibition prolongée de l’adénosine monophosphate cyclique (AMPc) entraînant des changements compensatoires dans la voie de l’adénylate cyclase. Pour cette étude, nous avons eu recours à un biosenseur basée sur la technologie de Bioluminescence Resonnance Energy Transfer (BRET) et qui fournit des mesures de l’AMPc en fonction du temps réel. Durant les 15 premières minutes de stimulation, la réponse de l’AMPc est bi-phasique. Cette progression de la réponse à l’AMPc n’est pas la même pour tous les ligands. Par exemple, la deltorphine II qui induit l’internalisation du récepteur opioïde delta (DOR) affiche une baisse de l’inhibition de l’AMPc. À l’inverse la morphine qui n’induit pas l’internalisation du DOR affiche une réponse stable à l’inhibition de l’AMPc. Ainsi le profil d’internalisation permet de prédire la progression de l’inhibition de l’AMPc à court terme (15 minutes). Nous avons aussi mesuré la réponse à l’AMPc durant 30, 60 et 120 min, étant donné qu’un traitement chronique aux opioïdes induit une tolérance analgésique. Selon les résultats obtenus, le profil d’internalisation du DOR induits par les ligands ne permet pas d’expliquer l’inhibition persistante de l’AMPc.

Lien entre l'activité pariéto-occipitale enregistrée pendant une tâche de mémoire à court terme visuelle et les habiletés mathématiques : une étude en magnétoencéphalographie

La mémoire à court terme visuelle (MCTv) est un système qui permet le maintien temporaire de l’information visuelle en mémoire. La capacité en mémoire à court terme se définit par le nombre d’items qu’un individu peut maintenir en mémoire sur une courte période de temps et est limitée à environ quatre items. Il a été démontré que la capacité en MCTv et les habiletés mathématiques sont étroitement liées. La MCTv est utile dans beaucoup de composantes liées aux mathématiques, comme la résolution de problèmes, la visualisation mentale et l’arithmétique. En outre, la MCTv et le raisonnement mathématique font appel à des régions similaires du cerveau, notamment dans le cortex pariétal. Le sillon intrapariétal (SIP) semble être particulièrement important, autant dans la réalisation de tâches liées à la MCTv qu’aux habiletés mathématiques. Nous avons créé une tâche de MCTv que 15 participants adultes en santé ont réalisée pendant que nous enregistrions leur activité cérébrale à l’aide de la magnétoencéphalographie (MEG). Nous nous sommes intéressés principalement à la composante SPCM. Une évaluation neuropsychologique a également été administrée aux participants. Nous souhaitions tester l’hypothèse selon laquelle l’activité cérébrale aux capteurs pariéto-occipitaux pendant la tâche de MCTv en MEG sera liée à la performance en mathématiques. Les résultats indiquent que l’amplitude de l’activité pariéto-occipitale pendant la tâche de MCTv permet de prédire les habiletés mathématiques ainsi que la performance dans une tâche de raisonnement perceptif. Ces résultats permettent de confirmer le lien existant entre les habiletés mathématiques et le fonctionnement sous-jacent à la MCTv.

Interview with Professor Mark Brodin about his book "William P. Homans Jr.: A Life In Court"

Boston lawyer William P. Homans Jr. devoted his fifty-year career to the defense of the poor and downtrodden, the protection of our most basic civil liberties, and the abolition of the death penalty. Descendant of two of Boston's oldest and most prominent families, and combat veteran of both the British and American Navies during World War II, Homans became unlikely guru to the 1960s generation of radical lawyers and antiwar activists. He was on the defense team in the 1968 conspiracy trial of Dr. Benjamin Spock and four other leading opponents of the Vietnam War accused of aiding and abetting resistance to the military draft, and represented Dr. Kenneth Edelin in the 1975 manslaughter prosecution arising out of a lawful abortion performed after Roe v. Wade. The narrative contrasts Bill Homans' storied legal career with a troubled personal life in a balanced but unvarnished manner, testifying to the strength of the human spirit when committed to the pursuit of the common good. About the author: Mark S. Brodin is Professor of Law at Boston College Law School and the author of numerous books and law journal articles in the areas of civil and criminal procedure, evidence, litigation, and employment discrimination. A graduate of Columbia College (1969) and Columbia Law School (1972), he served as law clerk to United States District Judge Joseph L. Tauro and staff attorney with the Lawyers' Committee for Civil Rights in Boston. He has also practiced for brief periods as a public defender in Boston and a prosecutor in Norfolk County.

Inherent Powers of the High Court under Section 482 of the Code of Criminal Procedure 1973

This thesis is shows the result of the research work on the inherent Powers of the High Court in criminal jurisdiction. The criminal justice system in India recognizes inherent powers only of the High Court. The Theory and Philosophy of inherent powers are concerned the Distinction between civil and Criminal laws are of very little consequence. In formulating the research programme the confusion created by the concept of inherent powers and its application by High Court form the central point. How fully the concept is understood, how correctly the power is used, and how far it has enhanced the rationale of the administration of criminal justice, what is its importance and what are the solutions for the inherent power to earn a permanent status in the province of criminal jurisprudence are the themes of this study. The precipitation of new dimensions is the yardstick to acknowledge the inherent powers of the High Court and Supreme Court. It is of instant value in criminal justice system. This study concludes innovativeness provided by the inherent powers has helped the justice administration draw inspiration from the Constitution. A jurisprudence of inherent powers has developed with the weilding of inherent powers of the Supreme Court and the High Court. It is to unravel mystery of jurisprudence caused by the operation of the concept of inherent powers this research work gives emphasis. Its significance is all the more relevant when the power is exercised in the administration of criminal justice. Application or non application of inherent powers in a given case would tell upon the maturity and perfection of the standard of justice

The Right to Water in the Case-Law of the Inter-American Court of Human Rights

The human right to water is nowadays more broadly recognised, mainly due to the essential societal function that this resource plays; likewise, because of the present water scarcity is generating conflicts between its different uses. Thus, this right aims at protecting human beings by guaranteeing access to clean water that is essential to satisfy vital human needs. Similarly, access to clean water is an important element to guarantee other rights including the right to life and health. The recognition of the right to water is mainly achieved in two ways: as a new and independent right and as a subordinate or derivative right. Concerning the latter, the right to water can emanate from civil and political rights, such as the right to life; or can be derived from economic, social and cultural rights, including the right to health, the right to an adequate standard of living, and the right to housing. This contribution explores the position of the Inter-American Court of Human Rights regarding the right to water, and analyses whether the Court has recognised the right to water and, if so, in which manner.

The Court of Justice of the European Union as a fundamental rights tribunal: challenges for the effective delivery of fundamental rights in the area of freedom, security and justice. CEPS Paper in Liberty and Security in Europe No. 49, 29 August 2012

This paper reflects on the challenges facing the effective implementation of the new EU fundamental rights architecture that emerged from the Lisbon Treaty. Particular attention is paid to the role of the Court of Justice of the European Union (CJEU) and its ability to function as a ‘fundamental rights tribunal’. The paper first analyses the praxis of the European Court of Human Rights in Strasbourg and its long-standing experience in overseeing the practical implementation of the European Convention for the Protection of Human Rights and Fundamental Freedoms. Against this analysis, it then examines the readiness of the CJEU to live up to its consolidated and strengthened mandate on fundamental rights as one of the prime guarantors of the effective implementation of the EU Charter of Fundamental Rights. We specifically review the role of ‘third-party interventions’ by non-governmental organisations, international and regional human rights actors as well as ‘interim relief measures’ when ensuring effective judicial protection of vulnerable individuals in cases of alleged violations of fundamental human rights. To flesh out our arguments, we rely on examples within the scope of the relatively new and complex domain of EU legislation, the Area of Freedom, Security and Justice (AFSJ), and its immigration, external border and asylum policies. In view of the fundamental rights-sensitive nature of these domains, which often encounter shifts of accountability and responsibility in their practical application, and the Lisbon Treaty’s expansion of the jurisdiction of the CJEU to interpret and review EU AFSJ legislation, this area can be seen as an excellent test case for the analyses at hand. The final section puts forth a set of policy suggestions that can assist the CJEU in the process of adjusting itself to the new fundamental rights context in a post-Lisbon Treaty setting.
