Accès aux médicaments : comment expliquer et améliorer la situation au Brésil

Le Brésil figure parmi les plus grands marchés consommateurs de médicaments. Cependant, le droit à l'accès aux médicaments, prévu dans sa Constitution Fédérale, ne fait pas partie de sa réalité. Cette situation est attribuable à plusieurs facteurs: le Brésil n'est pas capable de répondre à ses besoins internes et la consommation de médicaments n'est pas équilibrée. En réaction à cette constatation, nous analyserons la situation juridique actuelle du Brésil, afin d'indiquer les lacunes et barrières au plein accès aux médicaments et, surtout, de trouver une solution qui pourrait améliorer cette situation. Les organismes gouvernementaux brésiliens jouant un rôle important dans le développement des nouveaux médicaments sont présentés et, ensuite, l'encadrement juridique applicable à la recherche clinique et à l'autorisation de mise en marché des nouveaux médicaments est analysé; un bref survol de la législation applicable aux médicaments génériques est fait. Dans un deuxième moment de l'étude, la question d'accès aux nouveaux médicaments est mise en lumière: la législation brésilienne relative aux brevets, ainsi que le régime de licence obligatoire sont abordés; de plus, nous évaluons la compatibilité de ce régime avec l'Accord sur les ADPIC et nous évoquons les conflits internationaux qu'il a suscités. En vue de trouver des solutions aux difficultés brésiliennes identifiées, nous concluons notre étude avec l'examen de l'initiative canadienne pour favoriser l'accès aux médicaments aux pays du Sud (RCAN). Nous constatons que l'utilisation du RCAM pourrait, à court terme, favoriser l'accès aux médicaments au Brésil et, à moyen terme, aider à réduire les conflits internationaux. Finalement, à long terme, nous croyons que le Brésil pourrait jouer un rôle de leader international en adoptant une loi semblable à celle du Canada et, ainsi, il serait capable d'aider d'autres pays dans le besoin, qui n'ont aucune capacité de production locale, comme par exemple, plusieurs pays en Afrique.

Institutional Boundaries and Judicial Review - Some Thoughts on How the Court is Going About Its Business: Desperately Seeking Coherence

Justice constitutionnelle et subsidiarité : l'apport de l'expérience canadienne pour la construction européenne

La précision des critères d’application du principe de subsidiarité et le développement de son contrôle par les institutions politiques constituent un progrès vers un plus grand respect de ce principe ; ces avancées restent néanmoins insuffisantes à en prévenir toute violation. En droit canadien, le problème est similaire, la précision des critères de la clause Paix, Ordre et Bon Gouvernement et de la clause de commerce, si utile qu’elle soit, ne permet pas d’éviter tout conflit de loi. L’étude de la jurisprudence de la Cour de Justice montre ses réticences à procéder à un contrôle allant au-delà de la recherche d’une motivation formelle de la nécessité de l’intervention européenne. Pourtant, la comparaison de la capacité à agir des différents niveaux de gouvernements, capacité à agir évoluant dans le temps, ne peut se faire sans référence au contexte d’application de la norme. La Cour de Justice pourrait comme la Cour Suprême du Canada, expliciter dans ses décisions son appréciation de la capacité à agir de chaque niveau de gouvernement. La subsidiarité éclaire sous un jour nouveau la clause de commerce ou la doctrine de l’intérêt national, jusqu’alors parfois perçues comme permettant un développement constant et unilatéral des compétences fédérales au détriment de celles des provinces. L’efficacité du contrôle du principe de subsidiarité ne dépend pas seulement de la Cour qui le met en œuvre mais peut aussi dépendre des institutions politiques l’ayant saisi, de l’argumentation des requérants en particuliers.

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

Judicial Creativity in Constitutional Interpretation

The focus of study in this thesis is on the necessity and extent of judicial creativity in interpreting provisions in certain crucial areas in the Constitution of India. Judicial innovation was essential to adapt the constitutional provisions to modern changed context. Creativity of the Court has been mainly in the creation and introduction of certain new concepts not found in any specific provision of the Constitution which, but were essential for its meaningful interpretation.Independence of the judiciary, basic structure and certain elements of social justice cherished as ideal by the makers of the Constitution are some such concepts infused into the Constitution by the judiciary. The second aspect of creativity lies in the attempt of the Court to construe provisions in the Constitution with a view to upholding and maintaining the concepts so infused into the Constitution. Introduction of those concepts into the Constitution was necessary and is justified. all important features of the Constitution like democratic form of government, federal structure, judicial review, independence of judiciary and rule of law were thus included in the doctrine to prevent their alteration by amendments.As a result of such a construction, the nature of those directive principles itself has changed. They ceased to be mere directives for state action but became mandate for it. If left to legislative or executive will for their implementation, the directives would have remained enforceable as ordinary right.To conclude, notwithstanding the errors committed by the Supreme Court in construing the provisions in the above areas, they stand testimony to its creative and innovative response in interpreting the Constitution. If this trend is continued, it will be possible to achieve through the judicial process, maintenance of independence of the judiciary, avoidance of destruction of the Constitution through the process of amendment and realisation of social justice envisaged in the directive principles. It can be hoped that the Court would maintain its energetic and vibrant mind and rise up to the occasions and extend the same to other areas in future.

"Riesgo de oportunismo del Gobierno en el sector eléctrico colombiano". Aproximación al diseño institucional de la regulación eléctrica en Colombia

Análisis del riesgo de oportunismo del gobierno Colombiano planteado por el diseño institucional y normativo de la CREG, y favorecido por una notoria concentración de calidades en cabeza del Estado Colombiano como agente de mercado y regulador.

La travesía obsoleta: la indefensión del consumidor

La obsolescencia programada es el deseo de tener algo un poco más nuevo, un poco mejor, un poco más rápido de lo necesario. El texto estudia este fenómeno a la luz del Estatuto del Consumidor – Ley 1480 de 2011 para determinar si el consumidor colombiano está suficientemente protegido con él.

Análisis del dictamen No. 023-10-DTI-CC de la Corte Constitucional para el período de transición referente al “Tratado entre la República del Ecuador y la República Federal de Alemania sobre fomento y recíproca protección de inversiones de capital”: (Caso No. 0006-10-TI) [Jurisprudencia]

El presente trabajo analiza de manera crítica el pronunciamiento de la Corte Constitucional para el Período de Transición respecto al control constitucional de las denuncias de tratados bilaterales de inversiones de capital, tomando como caso de estudio el instrumento internacional suscrito entre Ecuador y Alemania, en el cual bajo una corriente constitucionalista, la Corte somete al crisol de la contradicción el contenido del Tratado Internacional con la normativa constitucional vigente. En aquel sentido, analizaremos cómo, a través de este polémico dictamen, se inicia una línea jurisprudencial en la que se configuran temas controversiales como el denominado control automático de constitucionalidad, y, el debate respecto a la soberanía estatal en cuanto al no sometimiento del Ecuador a arbitrajes comerciales internacionales en asuntos de índole comercial.

Work and Excessive Sleepiness among Brazilian Evening High School Students Effects on Days Off

Previous studies have revealed that students who work and study build up sleep deficits during the workweek, which can trigger a sleep rebound during days off. The objective of this study was to investigate the impact of working/non-working on sleepiness during days off among high school students. The study population, aged 14-21 years, attended evening classes in Sao Paulo, Brazil. For the study, the students completed questionnaires on living conditions, health, and work; wore actigraphs; and completed the Karolinska Sleepiness Scale (KSS). To predict sleepiness, a logistic regression analysis was performed. Excessive sleepiness was observed on the first day off among working students. Results suggest that working is a significant predictor for sleepiness and that two shifts of daily systematic activities, study and work, might lead to excessive daytime sleepiness on the first day off. Further, this observed excessive sleepiness may reflect the sleep debt accumulated during the workweek.

Microhabitat Selection of three Forest Understory Birds in the Brazilian Atlantic Rainforest

When assessing fragmentation effects on species, not only habitat preferences on the landscape scale, but also microhabitat selection is an important factor to consider, as microhabitat is also affected by habitat disturbance, but nevertheless essential for species for foraging, nesting and sheltering. In the Atlantic Rainforest of Brazil we examined microhabitat selection of six Pyriglena leucoptera (white-shouldered fire-eye), 10 Sclerurus scansor (rufous-breasted leaftosser), and 30 Chiroxiphia caudata (blue manakin). We radio-tracked the individuals between May 2004 and February 2005 to gain home ranges based on individual fixed kernels. Vegetation structures in core plots and fringe plots were compared. In C. caudata, we additionally assessed the influence of behavioural traits on microhabitat selection. Further, we compared microhabitat structures in the fragmented forest with those in the contiguous, and contrasted the results with the birds` preferences. Pyriglena leucoptera preferred liana tangles that were more common in the fragmented forest, whereas S. scansor preferred woody debris, open forest floor (up to 0.5 m), and a thin closed leaf litter cover which all occurred significantly more often in the contiguous forest. Significant differences were detected in C. caudata for vegetation densities in the different strata; the distance of core plots to the nearest lek site was significantly influenced by sex and age. However, core sites of C. caudata in fragmented and contiguous forests showed no significant differences in structure. Exploring microhabitat selection and behavior may greatly support the understanding of habitat selection of species and their susceptibility to fragmentation on the landscape scale.

Fragmentation drives tropical forest fragments to early successional states: A modelling study for Brazilian Atlantic forests

Land use leads to massive habitat destruction and fragmentation in tropical forests. Despite its global dimensions the effects of fragmentation on ecosystem dynamics are not well understood due to the complexity of the problem. We present a simulation analysis performed by the individual-based model FORMIND. The model was applied to the Brazilian Atlantic Forest, one of the world`s biodiversity hot spots, at the Plateau of Sao Paulo. This study investigates the long-term effects of fragmentation processes on structure and dynamics of different sized remnant tropical forest fragments (1-100 ha) at community and plant functional type (PFT) level. We disentangle the interplay of single effects of different key fragmentation processes (edge mortality, increased mortality of large trees, local seed loss and external seed rain) using simulation experiments in a full factorial design. Our analysis reveals that particularly small forest fragments below 25 ha suffer substantial structural changes, biomass and biodiversity loss in the long term. At community level biomass is reduced up to 60%. Two thirds of the mid- and late-successional species groups, especially shade-tolerant (late successional climax) species groups are prone of extinction in small fragments. The shade-tolerant species groups were most strongly affected; its tree number was reduced more than 60% mainly by increased edge mortality. This process proved to be the most powerful of those investigated, explaining alone more than 80% of the changes observed for this group. External seed rain was able to compensate approximately 30% of the observed fragmentation effects for shade-tolerant species. Our results suggest that tropical forest fragments will suffer strong structural changes in the long term, leading to tree species impoverishment. They may reach a new equilibrium with a substantially reduced subset of the initial species pool, and are driven towards an earlier successional state. The natural regeneration potential of a landscape scattered with forest fragments appears to be limited, as external seed rain is not able to fully compensate for the observed fragmentation-induced changes. Our findings suggest basic recommendations for the management of fragmented tropical forest landscapes. (C) 2011 Elsevier B.V. All rights reserved.

Stem cell Researches in Brazil: Present and Future Challenges

A bill allowing researches with human embryonic stem cells has been approved by the Brazilian Congress, originally in 2005 and definitively by the Supreme Court in 2008. However, several years before, investigations in Brazil with adult stem cells in vitro in animal models as well as clinical trials, were started and are currently underway. Here, we will summarize the main findings and the challenges of going from bench to bed, focusing on heart, diabetes, cancer, craniofacial, and neuromuscular disorders. We also call attention to the importance of publishing negative results on experimental trials in scientific journals and websites. They are of great value to investigators in the field and may avoid the repeating of unsuccessful experiments. In addition, they could be referred to patients seeking information, aiming to protect them against financial and psychological harm.

Variety matters: adaptive genetic diversity and parasite load in two mouse opossums from the Brazilian Atlantic forest

The adaptive potential of a species to a changing environment and in disease defence is primarily based on genetic variation. Immune genes, such as genes of the major histocompatibility complex (MHC), may thereby be of particular importance. In marsupials, however, there is very little knowledge about natural levels and functional importance of MHC polymorphism, despite their key role in the mammalian evolution. In a previous study, we discovered remarkable differences in the MHC class II diversity between two species of mouse opossums (Gracilinanus microtarsus, Marmosops incanus) from the Brazilian Atlantic forest, which is one of the most endangered hotspots for biodiversity conservation. Since the main forces in generating MHC diversity are assumed to be pathogens, we investigated in this study gastrointestinal parasite burden and functional associations between the individual MHC constitution and parasite load. We tested two contrasting scenarios, which might explain differences in MHC diversity between species. We predicted that a species with low MHC diversity would either be under relaxed selection pressure by low parasite diversity (`Evolutionary equilibrium` scenario), or there was a recent loss in MHC diversity leading to a lack of resistance alleles and increased parasite burden (`Unbalanced situation` scenario). In both species it became apparent that the MHC class II is functionally important in defence against gastrointestinal helminths, which was shown here for the first time in marsupials. On the population level, parasite diversity did not markedly differ between the two host species. However, we did observe considerable differences in the individual parasite load (parasite prevalence and infection intensity): while M. incanus revealed low MHC DAB diversity and high parasite load, G. microtarsus showed a tenfold higher population wide MHC DAB diversity and lower parasite burden. These results support the second scenario of an unbalanced situation.

Phylogeny and ecology determine morphological structure in a snake assemblage in the central Brazilian Cerrado

To investigate the role of ecological and historical factors in the organization of communities, we describe the ecomorphological structure of an assemblage of snakes (61 species in six families) in the Cerrado (a savanna-like grassland) of Distrito Federal, Brazil. These snakes vary in habits, with some being fossorial, cryptozoic, terrestrial, semi-aquatic, or arboreal. Periods of activity also vary. A multivariate analysis identified distinct morphological groups associated with patterns of resource use. We report higher niche diversification compared to snakes in the Caatinga (a semi-arid region in northeastern Brazil), with fossorial and cryptozoic species occupying morphological space that is not occupied in the Caatinga. Monte Carlo permutations from canonical phylogenetic ordination revealed a significant phylogenetic effect on morphology for Colubridae, Colubrinae, Viperidae, Elapidae, and Boidae indicating that morphological divergence occurred in the distant past. We conclude that phylogeny is the most important factor determining structure of this Neotropical assemblage. Nevertheless, our results also suggest a strong ecological component characterizes a peculiar snake fauna.
