This paper describes the main steps in the study of Senna spectabilis, as part of our bioprospection studies, with the isolation of spectaline, cassine and other piperidine alkaloids, as well as the preparation of semi-synthetic analogues, and the studies of their pharmacological and toxicological properties, which led to the establishment of two candidate drugs for the treatment of Alzheimer disease.

A anemia falciforme (AF) é a doença hematológica hereditária crônica de maior prevalência no Brasil, causada por uma mutação pontual no gene da β-globina, levando as hemácias a adquirirem formato de foice quando em estado desoxigenado. Essa alteração estrutural causa aumento da adesão celular, hipóxia local, vaso-oclusão e alterações na coagulação. O quadro clínico dos pacientes é diversificado, predominando a dor causada pelo processo inflamatório agudo e crônico, além de complicações que podem ocasionar infarto de tecidos e órgãos, levando à morte. O único fármaco aprovado pelo FDA disponível para o tratamento da doença é a hidroxiuréia (HU), mas, devido a sua toxicidade, têm sido intensificadas as buscas por novas possibilidades terapêuticas. O fator de necrose tumoral alfa (TNF-α) é uma citocina pró-inflamatória presente em grande quantidade nos pacientes portadores da doença, e o óxido nítrico pode contribuir para vasodilatação e proteção vascular. Assim, propôs-se a síntese e avaliação farmacológica de candidatos a fármacos para o tratamento da AF, desenhados com o propósito de apresentar propriedades inibidoras do TNF-α e doadoras de óxido nítrico (NO). Foi avaliada a estabilidade química dos compostos sintetizados, em água, pH 1,2 e pH 7,4, sendo o Composto II o mais estável tanto em pH ácido como em água. Em pH básico, todos os compostos se mostraram instáveis. Os compostos III e VI apresentaram uma maior inibição da agregação plaquetária, atividade também atribuída à capacidade de doação de NO. O composto III foi o único a mostrar-se inibidor de TNF-α e IL-1β, em todas as concentrações avaliadas, e, também, mostrou-se inibidor de NO, no teste induzido por LPS. Diante de todos os ensaios realizados, o composto III é o mais promissor candidato a fármaco, entre os compostos sintetizados, para o tratamento dos sintomas da anemia falciforme.

Currently it is clear that there are several factors that can act as modifiers of diseases, without causing them directly, but having the potential to make these conditions to progress faster and more severe. There is a growing number of studies investigating the relationship between Diabetes Mellitus (DM) and Periodontal Disease (PD), including some studies focusing on the influence of genetic factors in this process. The aim of this study was to verify through a literature review, the influence of genetic polymorphisms in the development of PD in patients with DM. PubMed and BIREME were used as databases and the terms Periodontitis or Periodontal Disease, Polymorphism, Diabetes Mellitus were searched. After a refinement in the literature, five studies were selected and they were related to chronic PD with DM and polymorphisms in cytokine genes, especially interleukin 1 (IL1) e IL6. Polymorphisms were associated with a higher concentration of pro-inflammatory cytokines in the gingival crevicular fluid of diabetic patients when compared to non-diabetic. In conclusion, it is necessary to confirm this association with longitudinal studies that must investigate a larger number of cytokine genes in order to understand the cause-effect relationship between genetic polymorphisms, DM and PD.

In this article the authors clinically compare the efficacy of two different anti-inflammatory drugs - Etoricoxib (Arcoxia®) and Diclofenac (Olfen®) – in the control of postoperative pain resulting from the surgical removal of impacted lower third molars. Fifteen patients requiring the extraction of bilaterally impacted lower third molars were selected at the Department of Oral and Maxillofacial Surgery at the Araraquara School of Dentistry – UNESP. The drugs were randomly administered during the first and second surgical procedures. Pain was evaluated by means of a visual analogic scale for 72 hours following the surgical procedure. After statistical analysis of the results, the authors concluded that there were no significant differences in terms of postopoerative pain control between the two drugs studied.

Aim: observe the knowledge of dental caries and periodontal disease of primary schoolteachers, according to type of institution (public and private) from Araraquara city. methodology: for that participants were 113 teachers from public schools and 57 from private schools. The instrument of analysis was based on a questionnaire with closed and open questions concerning the etiology, prevention and development of dental caries and periodontal disease. Results: 97,3% of public ́s schoolteachers and 91,2% of private ́s schoolteachers answered that they knows what is dental caries, but they didn ́t answer correctly about the caries etiology as being multifactorial and about methods of prevention. Both of schoolteachers (public and private) had more sucessful when answered about bacterial plaque than periodontal disease and yours manifestation. Conclusion: the dental knowledge of schoolteachers in public and private school was evaluated and limited educational programs should be directed to both public and private schoolteachers, in order to increase the level of dental knowledge of them, so that they can act as educational agents with the children.
