Photodynamic therapy for American cutaneous leishmaniasis: The efficacy of methylene blue in hamsters experimentally infected with Leishmania (Leishmania) amazonensis

The aim of this study was to investigate the effectiveness of Photodynamic Therapy (PDT) using Methylene Blue (MB) as the photosensitizing compound and a Light-Emitting Diode (LED) in American cutaneous leishmaniasis (ACL). Hamsters were experimentally infected with Leishmania (Leishmania) amazonensis. After the development of the lesions in the footpad, the animals were treated with MB three times a week for 3 months. Ten minutes after each application of MB, the lesions were irradiated with LED for 1 h. The lesions were evaluated weekly by the measurement of the hamster footpad thickness. At the end of the treatment the parasitic load was quantified in the regional lymph node of the hamsters. The treatment promoted a decrease in the thickness of infected footpad (P = 0.0001) and reduction in the parasitic load in the regional lymph node (P = 0.0007) of the animals from group treated with MB + LED. PDT using MB + LED in ACL caused by L. amazonensis shows a strong photodynamic effect. This therapy is very promising, once it is an inexpensive system and the own patient can apply it in their wound and in their house without the need of technical assistance. (C) 2011 Elsevier Inc.

O debate entre Hart e Fuller: uma controvérsia envolvendo veículos no parque

A debate occurred in 1958 at the Harvard Law Review has become a landmark for contemporary philosophy of law. Still under the philosophical and moral impact of the Second World War, Herbert L. A. Hart published his version of legal positivism whitin the article entitled Positivism and the Separation of Law and Moral. The answer came from Lon Fuller’s Positivism and Fidelity to Law – A Reply to Prof. Hart. Much of the debate took place over a seemingly prosaic exemple: a rule prohibiting vehicles from a park. With this exemple, Hart argued that rules have a core of clear aplications, but this core meaning would be sorrounded by a penumbra of uncertainty. Fuller uses a counter-exemple to instist that legal language, by itself, cannot determine a certain outcome: it is necessary to understand the purpose for wich the rule was suppose to serve. This paper analyses this controversy from its most important features: i) the connection between legal philosophy and philosophy of language; ii) the possibility of legal interpretation; iii) and the different possibles points of view for the analysis of law. This paper argues that the study of these features sheds light on the problems we encounter in contemporary philosophy of law, especialy with regard to theories of legal argumentation and its relation with legal langague and legal interpretation.

Structural challenges in a multipolar and multicultural global legal era : BRICS’ global legal politics beyond cultural and economic partnerships

New emerging international dynamics introduce a global poly-axiological polycentric disorder which undermines the tradition of a unique global legal order in international law. Modern Era was characterized by Western European civilizational model – from which human rights is a byproduct. This consensus had its legitimacy tested by XXst century’s scenario – and the ‘BRICS factor/actor’ is a symptom of this reality. Its empowerment in world politics lead to the rise of distinct groups of States/civilizations provided with different legal, political, economic and social traditions – promoting an unexpected uprise of otherness in international legal order and inviting it to a complete and unforeseeable reframing process. Beyond Washington or Brussels Consensus, other custom-originated discourses (Brasília, Moscow, New Delhi, Peking or Cape Town Consensus, among other unfolded possibilities) will probably henceforth attempt shaping international law in present global legal disorder.

A intervenção estatal no domínio econômico privado através da nova lei de recuperação de empresas e falências (lei 11.101/05)

Analysis of the elements of the Constitutional Order of the letter 1988 politics, with emphasis in the principles of this, a study on the intervention of the State in the private initiative by means of the Law of Recovery of Companies and Bankruptcies (law 11.101/05). New enterprise vision is admitted, over all in the interdependence between economic and social factors. Study on the globalization and the interdependence of economic and legal sciences in the construction of a legal optics in the search for the economic and social development, with the recognition of the interference of the Economy in the Right and its uneven importance. Still, we delineate the state intervention in the economic scope, of company and in the judicial recovery, as well as the consequences of such intervention in the involved credits in the judicial recovery and patrimony of the debtor in recovery. For such task, the elements of the Judicial Recovery, its principles and adequacy of these to the related ones in the chapter had been analyzed that turns on the national economic Order, describing the formal procedure for concession of the benefit of the Judicial Recovery and the principles in existing them. The forms of intervention of the State in the private economy were not disrespected, relating its direct and indirect performance as half of preservation of interests writings in the constitutional scope as public interest and preservation of the National economic Order. The regulating agencies as of direct state intervention were half not disrespected of the study for the relevance of the subject. It is revised national bibliography with incursions in French, Portuguese and North American comparative jurisprudence. One contributes in the aspect of the paper of the Judiciary Power in the protection of the companies in crisis and the social and economic impacts, over all in relation to the rights of the worked ones, credit and enterprise

Estimation of taurindicine hybridization of American Zebu cattle in Brazil

Our objective was to estimate Bos primigenius taurus introgression in American Zebu cattle. One hundred and four American Zebu (Nellore) cattle were submitted to mtDNA, microsatellite and satellite analysis. Twenty-three alleles were detected in microsatellite analysis, averaging 4.6 +/- 1.82/locus. Variance component comparisons of microsatellite allele sizes allowed the construction of two clusters separating taurus and indicus. No significant variation was observed when indicus and taurus mtDNA were compared. Three possible genotypes of 1711b satellite DNA were identified. All European animals showed the same restriction pattern, suggesting a Zebu-specific restriction pattern. The frequencies of B. primigenius indicus-specific microsatellite alleles and 1711b satellite DNA restriction patterns lead to an estimate of 14% taurine contribution in purebred Nellore.

Renal function evaluation in patients with American Cutaneous Leishmaniasis after specific treatment with pentavalent antimonial

Background: Renal evaluation studies are rare in American Cutaneous Leishmaniasis (ACL). The aim of this study is to investigate whether specific treatment reverts ACL-associated renal dysfunction. Methods: A prospective study was conducted with 37 patients with ACL. Urinary concentrating and acidification ability was assessed before and after treatment with pentavalent antimonial. Results: The patients mean age was 35.6 +/- 12 years and 19 were male. Before treatment, urinary concentrating defect (U/P-osm < 2.8) was identified in 27 patients (77%) and urinary acidification defect in 17 patients (46%). No significant glomerular dysfunction was observed before and after specific ACL treatment. There was no reversion of urinary concentrating defects, being observed in 77% of the patients before and in 88% after treatment (p = 0.344). Urinary acidification defect was corrected in 9 patients after treatment, reducing its prevalence from 40% before to only 16% after treament, (p = 0.012). Microalbuminuria higher than 30 mg/g was found in 35% of patients before treatment and in only 8% after treatment. Regarding fractional excretion of sodium, potassium, calcium, phosphorus and magnesium, there was no significant difference between pre and post-treatment period. Conclusion: As previously described, urinary concentrating and acidification defects were found in an important number of patients with ACL. Present results demonstrate that only some patients recover urinary acidification capacity, while no one returned to normal urinary concentration capacity.

Birth, Development and Progressive Institutionalization of the Ombudsman in the Russian Legal and Political System

One of the current trends in governance and legal development in Russia is aimed at establishing a modern, efficient and internationally harmonised system of safeguards of human rights and civil liberties. A fairly recent addition to this system has been the institution of ombudsman as a public authority specialised in promoting and protecting human rights and civil liberties. The introduction of this institution as well as its formalisation at the constitutional and legislative levels has been increasingly relevant and important, as it raises the dealings between the state and the individual to a new level. As an independent public institution resolving conflicts between citizens and government authorities, the ombudsman makes steps, within the scope of his jurisdiction, to restitute individual rights, and helps to enhance the reputation of government. The present work describes and assesses the birth, development and institutionalization process of the Ombudsman Office in the Russian Federation, at federal and regional levels, with a particular emphasis on the role of international references and cooperation for institution building. Ombudsmen have done a magnificent job in demonstrating value with the resolution of individual and systemic complaints; subsequent improvements to government; and economic savings by mitigating litigation costs.

'Security Here is Not Safe': Violence, Punishment, & Space in the Contemporary U.S. Penitentiary

The US penitentiary at Lewisburg, Pennsylvania, was retrofitted in 2008 to offer the country’s first federal Special Management Unit (SMU) program of its kind. This model SMU is designed for federal inmates from around the country identified as the most intractably troublesome, and features double-celling of inmates in tiny spaces, in 23-hour or 24-hour a day lockdown, requiring them to pass through a two-year program of readjustment. These spatial tactics, and the philosophy of punishment underlying them, contrast with the modern reform ideals upon which the prison was designed and built in 1932. The SMU represents the latest punitive phase in American penology, one that neither simply eliminates men as in the premodern spectacle, nor creates the docile, rehabilitated bodies of the modern panopticon; rather, it is a late-modern structure that produces only fear, terror, violence, and death. This SMU represents the latest of the late-modern prisons, similar to other supermax facilities in the US but offering its own unique system of punishment as well. While the prison exists within the system of American law and jurisprudence, it also manifests features of Agamben’s lawless, camp-like space that emerges during a state of exception, exempt from outside scrutiny with inmate treatment typically beyond the scope of the law.

Multilingualism, Legal Drafting and Interpretation of Bilingual Law in Italy

The article begins with a short history of the current Italian language, as an example of a dialect evolving and becoming elevated to the status of a national language. Next, an overview of Italy as characterized by multilingualism and of the different minority languages is offered. A third part is devoted to the different legal languages of Italian law and particularly to the consequences of multilingualism in Italy, which refers to the obligation to draft some local laws in two or tree languages. Multilingual drafting concerns institutions – and therefore concepts – of Italian law which are applied within one single legal system, namely the Italian one, and are merely expressed in a legal language which is not only Italian, but German, French or Ladin. This part is discussed more in deep. The article underlines that legal multilingualism in Italy is a rather unexplored research field. As in Europe there is a clear need for studies inquiring the problem of intepretation and application of mulitlingual law, the praxis and the operative reality of the “regional” legal languages in Italy would probably deserve more attention.
