Using ELISA technique, natural antibodies against self and non self antigens were determined in 80 patients chronically intected by T. cruzi and 40 individuals suffering from a deep mycosis frequentely found in Latin Amarica (Paracoccidioidomycosis - PCM). Two forms of PCM were investigated: adult forms and juvenil type of disease. Eighty percent (80%) of the former group had significantly elevated anti-laminin antibody levels (M=4.7,SD±1.8) compared with healthy controls and different specificities of antibody were associated with anti-laminin in pathological sera. A notable binding to cytoskeletal proteins was observed, specially with band 3 and their peptides derivates, such as 62 kDa peptide. By means of Protein A chromatography we were able to show that natural anti-Gal antibodies may be bound by their Fab region to other immunoglobulins and/or to Protein A by alternative sites of binding. The finding of lgG anti-Gal antibodies in circulating immune complexes isolated from chagasic sera supported the first alternative. However, it is possible that some of lgG anti-Gal antibodies, belong to VH111 subgroup of immunoglobulins, that bind directly to Protein A. Among the 40 sera from PCM examined, the majority was considered as not exhibiting a signilicantly higher binding than normal sera to antigens tested. However thirty percent (30%) of the chronic patients had an increased levels of natural antibodies at least for one specificity such as actyn, myosin and Gala1,3Gal epitopes. ln juvenil type of PCM the mean value found for actyn was also increased 2,42 (range 1,0 to 5,3). Utilizing the polyethylene glicol precipitation the presence of circulating immune complexes was investigated in PCM sera. Specific antibodies for soluble antigens from P. brasiliensis and natural antibodies against myoglobin, myosin and Gala1,3 Gal epitopes were characterized

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

Decisions are made constantly in organizational contexts; however, a wrong decision can bring undesirable consequences for organizations. In this sense, access to organic information becomes essential considering that decreases the uncertainties of managers in relation to decision making process. In this perspective, the identification of documental types from its production provides a consistent documental cycle, which will result in the recovery of information at the time requested by managers. Based on the above it was intended to verify what documental types recurrently used in the decision making process of a hospital company in the Bauru region, Sao Paulo State. For that, we applied the method 'Case Study' of Yin. We analyzed the information type that provided more security to the decision maker during the decision making. As a result, we elaborated a systematic documental organic types most used and most relevant to the decision-making process of the company, showing that when they are defined from the production of documents, the benefits for both the professional as archivist for the organization are significant.

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

A Anfotericina B é o fármaco antifúngico referência desde a sua descoberta na década de 50 até os dias atuais para o tratamento de infecções fúngicas sistêmicas. O objetivo do trabalho é realizar uma revisão bibliográfica que forneça os sistemas de liberação comercializados e os que estão em estudo, focando estratégias tecnológicas que possam servir para resolver os problemas da baixa solubilidade em água e da alta nefrotoxicidade da Anfotericina B. A AmB é um fármaco que apresenta inexpressiva solubilidade em meio-aquoso, principalmente na região de pH dos fluídos biológicos (7,4–8,0), sendo administrado atualmente por via endovenosa. Justificando a importância desse estudo para a área farmacêutica, novos sistemas de liberação que usem a via oral, aumentarão a adesão por crianças e idosos, além de aumentar o arsenal terapêutico e diminuir os gastos com hospitalizações. Por ter a sua utilidade clínica limitada em razão de sua alta toxicidade, tem-se buscado direcionar a AmB especificamente para o fungo ou pelo menos para o local da infecção, mantendo-se longe o fármaco das células hospedeiras. Para isso, se busca diferentes veículos que não o desoxicolato (Fungizone). Por fim, as formulações lipídicas mostram-se com maior eficácia e com menor toxicidade comparadas a Anfotericina B-desoxicolato, mas não fazem parte da rotina hospitalar em razão do seu alto custo
