The interventions took place in the Cultural Occupation Project developed by the Student Assistance Program (PAE) of the Technical College of Teresina (CTT), a school linked to the Federal University of Piauí (UFPI). There was a program, together with the students, for the “Yellow September”, which included talk wheels on the patio, lecture, film debate and workshop. The results indicated that it is crucial to speak openly, and responsibly, about ending life itself and the issues surrounding this experience. The proposal of care and intervention in health at school was based, above all, on the process of breaking the taboos on suicide, through spaces that favored discussion and welcomed students in a careful way, including them as social actors. The intervention was able to give visibility to a generally muted subject and was evidenced as a strategic tool for suicide prevention, to welcome without judgment, to listen with empathy, to identify the emotions and to learn to manage them with parsimony. It enabled the PAE team to strengthen ties with students, facilitating dialogue about suicide and avoiding to enter into the complicity of the silence that leads to denial or minimization of the problem. It is hoped the continuity of the actions involving this theme, which presents itself as a challenge for health professionals and education.

The goal of this paper was to investigate the chemical composition of the volatile oils obtained from leaves and stems of Philodendron meridionale Buturi & Sakur by gas chromatography/mass spectrometry and to evaluate their insecticidal effect against Ctenocephalides felis Bouche adult insects and their cytotoxicity on human Jurkat leukemic T-cells by 3-(4,5-dimethylthiazol-2-yl)-2,5diphenyltetrazoluim bromide (MTT) reduction method. The main compound was ent-kaur-16-ene at concentrations of 20.78 and 22.46% for volatile oils from leaves and stems, respectively. These volatile oils provided insecticidal effect against C. felis with an average knockdown time of 9.61 and 7.35 min for fumigant test performed with the leaves and stems samples, respectively. Considering the topical application, these P. meridionale volatile oils extracted from leaves and stems demonstrated avera...

O objetivo deste estudo foi realizar uma investigacao anatomica e analise de folhas de S. werstermanii atraves de microscopia otica e de microscopia eletronica de varredura eletronica. Foram preparadas lâminas semipermanentes com o material seccionado nos sentidos transversal e longitudinal, a mao livre e realizou-se o uso de reativos especificos, conforme literatura. Os caracteres anatomicos evidenciados neste estudo caracterizam a especie. As folhas sao anfiestomaticas e estomatos anomociticos, que estao em maior quantidade na face abaxial. Os tricomas tectores unisseriados estao presentes em ambas as faces, porem em maior numero na face abaxial. Na nervura central das folhas graos de amidos estao presentes proximo ao feixe vascular.

O objetivo desta revisão é fornecer um resumo conciso das pesquisas publicadas nos últimos 10 anos com ênfase na espécie Ilex paraguariensis, suas características gerais, composição química e seus principais benefícios à saúde. Este estudo é uma revisão exploratória descritiva da literatura a respeito da atividade biológica e ação farmacológica da planta Ilex paraguariensis A. St. - Hill. As bases de dados Scientific Electronic Library Online (Scielo), National Library of Medicine (Pubmed), Scopus e Academic Google foram utilizadas para a pesquisa. Os principais compostos químicos identificados no extrato de erva-mate são: polifenóis (ácido clorogênico) e xantinas (cafeína e teobromina). Entre os efeitos potencialmente benéficos à saúde humana estão atividades como: antioxidante, antiinflamatório, antimicrobiano, antiobesidade, antidiabétic...
