Televisão Digital: novos meios, novas narrativas

Grandes mudanças de ordem tecnológica e social colaboraram para a transformação na forma de comunicação do homem ao longo da história, que compartilha informações e transforma conceitos através de novos meios e novas narrativas, construindo e reconstruindo informações. O compartilhamento desses novos conteúdos vem colaborar na divulgação de diversidades culturais e regionais de todo o país fazendo jus a um dos objetivos da televisão digital que é a democratização da informação e do conhecimento.

Solid phase microextraction and LC-MS/MS for the determination of paliperidone after stereoselective fungal biotransformation of risperidone

The present work describes for the first time the use of SPME coupled to LC-MS/MS employing the polar organic mode in a stereoselective fungal biotransformation study to investigate the fungi ability to biotransform the drug risperidone into its chiral and active metabolite 9-hydroxyrisperidone (9-RispOH). The chromatographic separation was performed on a Chiralcel OJ-H column using methanol:ethanol (50:50, v/v) plus 0.2% triethylamine as the mobile phase at a flow rate of 0.8 mL min(-1). The SPME process was performed using a C18 fiber, 30 min of extraction time and 5 min of desorption time in the mobile phase. The method was completely validated and all parameters were in agreement with the literature recommendations. The Cunninghamella echinulata fungus was able to biotransform risperidone into the active metabolite, (+)-9-RispOH, resulting in 100% of enantiomeric excess. The Cunninghamella elegans fungus was also able to stereoselectively biotransform risperidone into (+)- and (-)-9-RispOH enantiomers at different rates. (C) 2012 Elsevier B.V. All rights reserved.

As cadeiras extintas da Academia de Direito de São Paulo

A Academia de Direito de São Paulo, fundada em 1827 por Decreto Imperial, em toda a sua jornada de grade disciplinar evoluiu em consonância aos necessários procedimentos, caminhando na construção de uma tutela doutrinal e jurisprudencial, atendendo não-só a sociedade como, também, à correta busca de uma nação voltada à segurança no intuito de assegurar uma democracia plena de Direito. Desde a criação dos cursos jurídicos não há uma cadeira em seu currículo - incluso as extintas por decretos governamentais - que não fosse de suma importância no período de sua vigência, a exemplo da intitulada Hygiene Publica lecionada por Augusto Cezar de Miranda Azevedo, Catedrático por Decreto de 21 de março de 1891, dando origem ao Direito Sanitário atualmente vinculado à Medicina, área de Saúde Pública, ou Direito Nacional e Direito Natural, dando margem ao Direito do Estado e à Introdução à Ciência do Direito. A Cadeira de Direito das Gentes, inicialmente inserida em parceria ao Direito Natural, deu margem ao Direito Internacional Público lecionada por José Maria Avelar Brotero, em 1828, tornando-se, na História da Academia de Direito como das mais importantes disciplinas da grade curricular.

Project Financing nelle Infrastrutture del Trasporto

L’elaborato ha avuto ad oggetto l’analisi delle sofisticate soluzioni normative proposte dall’ordinamento nazionale in relazione all’evoluzione della finanza di progetto. In particolare, è stata condotto un dettagliato studio delle fasi che compongono il project financing, nonché dei soggetti che, a diverso titolo e ragione, vi partecipano. L’elaborato contiene, poi, recenti esempi concreti di project financing nelle infrastrutture primarie (autostrade) tra cui il progetto di costruzione e la successiva gestione dell’autostrada regionale Medio Padana veneta, dell’autostrada regionale Cispadana, e dell’autostrada “Nogara-mare”. L’ultimo parte della tesi è stata infine incentrata sull’analisi delle più recenti pronunce giurisprudenziali in materia di project financing. In particolare, si ha avuto modo di analizzare il fenomeno dello jus poenitendi dell’amministrazione aggiudicatrice, nonché, più in generale gli eventi che possono negativamente incidere sulla finanza di progetto (mancata aggiudicazione, risoluzione del contratto di gestione, ecc.).

Drug metabolism in human brain: high levels of cytochrome P4503A43 in brain and metabolism of anti-anxiety drug alprazolam to its active metabolite.

Cytochrome P450 (P450) is a super-family of drug metabolizing enzymes. P450 enzymes have dual function; they can metabolize drugs to pharmacologically inactive metabolites facilitating their excretion or biotransform them to pharmacologically active metabolites which may have longer half-life than the parent drug. The variable pharmacological response to psychoactive drugs typically seen in population groups is often not accountable by considering dissimilarities in hepatic metabolism. Metabolism in brain specific nuclei may play a role in pharmacological modulation of drugs acting on the CNS and help explain some of the diverse response to these drugs seen in patient population. P450 enzymes are also present in brain where drug metabolism can take place and modify therapeutic action of drugs at the site of action. We have earlier demonstrated an intrinsic difference in the biotransformation of alprazolam (ALP) in brain and liver, relatively more alpha-hydroxy alprazolam (alpha-OHALP) is formed in brain as compared to liver. In the present study we show that recombinant CYP3A43 metabolizes ALP to both alpha-OHALP and 4-hydroxy alprazolam (4-OHALP) while CYP3A4 metabolizes ALP predominantly to its inactive metabolite, 4-OHALP. The expression of CYP3A43 mRNA in human brain samples correlates with formation of relatively higher levels of alpha-OH ALP indicating that individuals who express higher levels of CYP3A43 in the brain would generate larger amounts of alpha-OHALP. Further, the expression of CYP3A43 was relatively higher in brain as compared to liver across different ethnic populations. Since CYP3A enzymes play a prominent role in the metabolism of drugs, the higher expression of CYP3A43 would generate metabolite profile of drugs differentially in human brain and thus impact the pharmacodynamics of psychoactive drugs at the site of action.
