Santos, Sales Augusto dos;Cavalleiro, Eliane;Barbosa, Maria Inês da Silva;Ribeiro, Matilde;
Revista Estudos Feministas , 2008, DOI: 10.1590/S0104-026X2008000300012
Abstract: the article analyses the importance of the role of the state for the implementation of public policies of affirmative action, especially for black students to enter public higher education. it argues that affirmative action is one of the alternatives to reduce or minimize the inequality in this field between black and white students and/or students from public schools and private schools, in particular by means of one of its techniques of implementation: the quota system. in spite of there being various arguments against the quota system, the authors concentrate on debating or counter-arguing only one: that the quota system may generate racial conflicts in brazil.

Revista de Enfermagem UFPE On Line , 2010,
Abstract: Objective: to outline the evolution of concepts of pain in the newborn and measures for its control. Methodology: this is a descriptive literature study from the literature review type. The articles used were published in the last decade, from 1998 to 2008. Data collection took place between August and September 2008. To search the Virtual Health Library (VHL) and other sources were used descriptors: nursing, pain and newborn. Were considered thirty-five publications they are referred to the aim of this study. The texts were read, analyzed, organized and classified according to the following categories: concept and management of pain in infants. Results: the pain is discussed since the dawn of humanity and studied by several civilizations. At first it was believed that the newborn did not feel pain, today not only does the pain of the RN as something scientifically proven, but it also proposes measures for its control. These measures are pharmacological and nonpharmacological. Conclusion: Despite technological advances and studies, perceived that it is scarce literature on the subject and also there are few studies related to pain in neonatal nursing. Further studies are needed to further investigations and improvement of care in neonatology.

Abstract: Nevirapine (NVP) is an anti-HIV drug associated with severe hepatotoxicity and skin rashes, which raises concerns about its chronic administration. There is increasing evidence that metabolic activation to reactive electrophiles capable of reacting with bionucleophiles is likely to be involved in the initiation of these toxic responses. Phase I NVP metabolism involves oxidation of the 4-methyl substituent and the formation of phenolic derivatives that are conceivably capable of undergoing further metabolic oxidation to electrophilic quinoid species prone to react with bionucleophiles. The covalent adducts thus formed might be at the genesis of toxic responses. As part of a program aimed at evaluating the possible contribution of quinoid derivatives of Phase I phenolic NVP metabolites to the toxic responses elicited by the parent drug, we have investigated the oxidation of 2-hydroxy-NVP with dipotassium nitroso-disulfonate (Frémy’s salt), mimicking the one-electron oxidation involved in enzyme-mediated metabolic oxidations. We report herein the isolation and full structural characterization of a 1H-pyrrole-2,5-dione derivative as a major product, stemming from an unusual pyridine ring contraction.
