The use of long acting sulfonamides, alone or with pyrimethamine, in malaria (with special reference to sulformetoxine)

Review of the early literature as well as more recent results show that sulfonamides possess a distinct antimalarial activity. However, when give alone, their action is less marked and slower than that of the antimalarials commonly used in the treatment of the acute attack. Combinations with pyrimethamine provide better results, even in cases of pyrimethamine and chloroquine resistance. This warrants further investigations in an attempt to develop a therapeutic agent suitable for the treatment of such resistant cases. It may also be possible with an appropriate combination of pyrimethamine with a sulfonamide to achieve a satisfactory method for suppressive treatment both in areas with and without pyrimethamine resistance. Three main points must still be carefully studied: 1) the risk of developing malaria resistance against one or both of the components of the combination. 2) The risk of developing bacterial resistance to sulfonamides if these substances are used on a large scale in too low doses. It seems indeed that antimalarial effect with the combination of sufonamides + pyrimethamine can be obtained with doses of sulfonamides which are below those usually employed in bacterial diseases. Since the range of the ratios providing potentiation is rather large, only ratios of the combination sulfonamides: pyrimethamine should be chosen in which an antfbacterial sulfonamidemia is guaranteed. 3) It goes without sayinq that, although both pyrimethamine and modem sulfonamides, when given by themselves, have proved tc possess a large margin of safety, long term administration of their combination should be careful studied from the point of view of possible side effects. Substantial evidence has already been produced to show that the long acting sulfonamide Fanasil (Ro 4-4393) given once or once weekly possesses marked schizonticidal activity against P. falciparum. Although its action is slower than that of 4-aminoquinolines, it may be useful as a second choice drug in semi-immune subjects for the therapy of falciparum malaria. Preliminary results show that, when combined with pyrimethamine, Fanasil is highly effective in suppressing fever and asexual parasitemia due to P. falciparum. Single doses of 1 g Fanasil together with 50 mg pyrimethamine seem to be adequate for the treatment of acute falciparum malaria in semi-immune patients. The onset of action of the combination is much more rapid than that of the single components. Weekly doses of 500 mg Fanasil and 25 mg pyrimeihamine appear to provide satisfactory suppressive effects against P. falciparum at least in East Africa. This combination is active on strains which do not respond satisfactorily to the standard doses of pyrimethamine and/or chloroquine and seems to have a satisfactory sporontocidal effect. Preliminary results indicate that Fanasil alone cannot be recommended for use against the other human malaria parasites. The combination with pyrimethamine appears to be much more effective. East African strains of P. malariae seem to respond better to the combination than do Malayan strains of P. vivax but further trials are required before definite assessment can be made. Fanasil by itself has no gametocytoddal or sporontocidal action but seems to potentiate the effect of pyrimethamine at least on sporogony of P. falciparum.

José Mourinho, The special one: A pedagogical case

The purpose of this work is to create a case to reflect about the leadership role of José Mourinho in Real Madrid CF, considering his successful background experiences in FC Porto, Chelsea FC and FC Inter. The case is based on the failure of the Special One in Real Madrid CF. This paper is mainly focused in the leadership process, charismatic leadership and contingency theory of leadership. Moreover it is intended to introduce concepts about the influence of leaders in the organizational culture, the management of human resources, and the role of a leader adapting to a different context.

Treatment of American tegumentary leishmaniasis in special populations: a summary of evidence

We aimed to assess and synthesize the information available in the literature regarding the treatment of American tegumentary leishmaniasis in special populations. We searched MEDLINE (via PubMed), EMBASE, LILACS, SciELO, Scopus, Cochrane Library and mRCT databases to identify clinical trials and observational studies that assessed the pharmacological treatment of the following groups of patients: pregnant women, nursing mothers, children, the elderly, individuals with chronic diseases and individuals with suppressed immune systems. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The available evidence suggests that the treatments of choice for each population or disease entity are as follows: nursing mothers and children (meglumine antimoniate or pentamidine), patients with renal disease (amphotericin B or miltefosine), patients with heart disease (amphotericin B, miltefosine or pentamidine), immunosuppressed patients (liposomal amphotericin), the elderly (meglumine antimoniate), pregnant women (amphotericin B) and patients with liver disease (no evidence available). The quality of evidence is low or very low for all groups. Accurate controlled studies are required to fill in the gaps in evidence for treatment in special populations. Post-marketing surveillance programs could also collect relevant information to guide treatment decision-making.

A consagração dos naturais

“One cannot analyse a legal concept outside the economic and socio-cultural context in which it was applied” – such is the longstanding thesis of António Manuel Hespanha. I argue that Hespanha’s line of argument relative to legal concepts is also applicable, mutatis mutandis, to legal agents: the magistrates, advocates, notaries, solicitors and clerks who lived and exercised their professions in a given time and place. The question, then, is how to understand the actions of these individuals in particular contexts – more specifically in late 18th century and 19th century Goa. The main goal of the present thesis was to comprehend how westernized and Catholic Goan elite of Brahman and Chardó origin who provided the majority of Goan legal agents used Portuguese law to their own advantage. It can be divided into five key points. The first one is the importance of the Constitutional liberalism regime (with all the juridical, judicial, administrative and political changes that it has brought, namely the parliamentary representation) and its relations with the perismo – a local political and ideological tendency nurtured by Goan native Catholic elite. It was explored in the chapter 2 of this thesis. The second key point is the repeated attempts made by Goan native Catholic elite to implement the jury system in local courts. It was studied in the chapter 3. Chapter 4 aims to understand the participation of the native Catholic elite in the codification process of the uses and traditions of the indigenous peoples in New Conquests territory. The fourth key point is the involvement of those elites not only in the conflict of civil and ecclesiastical jurisdictions but also in the succession of the Royal House of Sunda. It was analyzed in the chapter 5. The functions of an advocate could be delegated to someone who, though lacking a law degree, possessed sufficient knowledge to perform this role satisfactorily. Those who held a special licence to practice law were known as provisionários (from provisão, or licence, as opposed to the letrados, or lettered). In the Goa of the second half of the 18th century and the 19th century, such provisionários were abundant, the vast majority coming from the native Catholic elite. The characteristics of those provisionários, the role played by the Portuguese letrados in Goa and the difficult relations between both groups were studied in the chapter 6.

A generic treatment of Alismatidae in the Neotropics with special reference to Brazil

A Subclasse Alismatidae nos neotrópicos é composta de nove famílias com 11 gêneros das quais, nove ocorrem na bacia amazônica e cinco no Brasil extra-amazônico. Apenas duas famílias não estão presentes no Brasil e mais duas ausentes da Amazônia brasileira. Este trabalho apresenta descrições detalhadas das famílias e gêneros, além de comentários sobre distribuição geográfica dos gêneros. As famílias estão organizadas na sequência sistemática que nós aceitamos. Os gêneros de cada família estão organizados em ordem alfabética i=sem significado sistemático. Fornecemos desenhos de pelo menos um gênero para cada família. Referências importantes -- tais como revisões genéricas, levantamentos da literatura, ou monografias de áreas neotropicais — estão relacionadas no início de cada tratamento a nível de família. As excelentes coleções do Projeto Flora Amazônica foram de importância decisiva para nosso trabalho-, sem elas não poderiamoi fazer um tratamento genérico completo para toda a região neotrópica.

Introduction to special Issue: future priorities in European media and communication research

(Excerto) The European Journal of Communication seeks to present the best in current research in the broad field of media and communication research. Irregularly, we seek to take stock by inviting a small group of leading scholars to present their work at a symposium on a common theme, which then forms the basis for a Special Issue of the Journal. In 2014, the European Science Foundation (ESF) published one of their ‘Forward Looks’ entitled Media in Europe: New Questions for Research and Policy. We subsequently invited several of the Forward Look’s authors to meet and discuss their work with us at a symposium hosted by the European University Cyprus, and the discussion and revised papers that resulted are published here.

Optimización en el cómputos de algoritmos de cuadratura para funciones especiales. Optimization of quadrature algorithms for special functions.

En nuestro proyecto anterior aproximamos el cálculo de una integral definida con integrandos de grandes variaciones funcionales. Nuestra aproximación paraleliza el algoritmo de cómputo de un método adaptivo de cuadratura, basado en reglas de Newton-Cote. Los primeros resultados obtenidos fueron comunicados en distintos congresos nacionales e internacionales; ellos nos permintieron comenzar con una tipificación de las reglas de cuadratura existentes y una clasificación de algunas funciones utilizadas como funciones de prueba. Estas tareas de clasificación y tipificación no las hemos finalizado, por lo que pretendemos darle continuidad a fin de poder informar sobre la conveniencia o no de utilizar nuestra técnica. Para llevar adelante esta tarea se buscará una base de funciones de prueba y se ampliará el espectro de reglas de cuadraturas a utilizar. Además, nos proponemos re-estructurar el cálculo de algunas rutinas que intervienen en el cómputo de la mínima energía de una molécula. Este programa ya existe en su versión secuencial y está modelizado utilizando la aproximación LCAO. El mismo obtiene resultados exitosos en cuanto a precisión, comparado con otras publicaciones internacionales similares, pero requiere de un tiempo de cálculo significativamente alto. Nuestra propuesta es paralelizar el algoritmo mencionado abordándolo al menos en dos niveles: 1- decidir si conviene distribuir el cálculo de una integral entre varios procesadores o si será mejor distribuir distintas integrales entre diferentes procesadores. Debemos recordar que en los entornos de arquitecturas paralelas basadas en redes (típicamente redes de área local, LAN) el tiempo que ocupa el envío de mensajes entre los procesadores es muy significativo medido en cantidad de operaciones de cálculo que un procesador puede completar. 2- de ser necesario, paralelizar el cálculo de integrales dobles y/o triples. Para el desarrollo de nuestra propuesta se desarrollarán heurísticas para verificar y construir modelos en los casos mencionados tendientes a mejorar las rutinas de cálculo ya conocidas. A la vez que se testearán los algoritmos con casos de prueba. La metodología a utilizar es la habitual en Cálculo Numérico. Con cada propuesta se requiere: a) Implementar un algoritmo de cálculo tratando de lograr versiones superadoras de las ya existentes. b) Realizar los ejercicios de comparación con las rutinas existentes para confirmar o desechar una mejor perfomance numérica. c) Realizar estudios teóricos de error vinculados al método y a la implementación. Se conformó un equipo interdisciplinario integrado por investigadores tanto de Ciencias de la Computación como de Matemática. Metas a alcanzar Se espera obtener una caracterización de las reglas de cuadratura según su efectividad, con funciones de comportamiento oscilatorio y con decaimiento exponencial, y desarrollar implementaciones computacionales adecuadas, optimizadas y basadas en arquitecturas paralelas.
