Felicidad como fuerza en la promoción de la salud del adolescente y adulto joven

to assess the relation between sociodemographic characteristics of young people associated with the subjectivity of being happy; to evaluate the relationship between the subjectivity of being happy and the perception of health status; to evaluate the relationship between the subjectivity of being happy and the school and family environments and peer groups at school.Objetivos: avaliar a relação entre as características sociodemográficas dos jovens associadas à subjetividade de ser feliz; avaliar a relação entre a subjetividade de ser feliz e a percepção do estado de saúde; avaliar a relação entre a subjetividade de ser feliz e o ambiente escolar, familiar e grupo de pares na escola. Métodos: estudo observacional, com amostra intencional de 1.069 jovens portugueses, entre 14 e 24 anos, maioria do sexo feminino, que frequenta o ensino secundário. Utilizou-se o questionário de autopreenchimento. Resultados: destacam-se associações estatisticamente significativas entre a subjetividade de ser feliz e a escolaridade, a percepção do estado de saúde, APGAR Familiar, o envolvimento escolar e familiar, ausência de problemas ou provocações pelos pares na escola. Conclusões: um cuidado positivo e holístico aliado ao potencial de obtenção e consolidação de padrões de vida saudáveis dos jovens permitirá aos profissionais de saúde percebê-los como agentes de mudança individual e social.Objetivos: evaluar la relación entre las características sociodemográficas de los jóvenes asociadas con la subjetividad de ser feliz; evaluar la relación entre la subjetividad de ser feliz y la percepción del estado de salud; evaluar la relación entre la subjetividad de ser feliz y el ambiente escolar, familiar y grupo de pares en la escuela.

External Morphology and Ultra-Structure of Eggs and First Instar of Prepona Laertes Laertes (Hübner, [1811]), with Notes on Host Plant use and Taxonomy

The external morphology and the tegument ultra-structure of Prepona laertes laertes (Hübner, [1811]) (Lepidoptera: Nymphalidae: Charaxinae) eggs and first instar larvae feeding on Inga spp. (Fabaceae) in a forest fragment in Joinville, Santa Catarina, Brazil, are described. Descriptions of the morphology with illustrations are presented, based upon observations through scanning electron microscopy and stereoscopic and optic microscopes attached to a camera lucida. Descriptions and illustrations of the head capsule, chaetotaxy, tegument, and setae are presented. The taxonomy, morphological characters, and host plant use of Prepona laertes immature stages are discussed

Nuclear expression of Rac1 in cervical premalignant lesions and cervical cancer cells

<p>Abstract</p> <p>Background</p> <p>Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines.</p> <p>Methods</p> <p>Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766).</p> <p>Results</p> <p>Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells.</p> <p>Conclusion</p> <p>Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression.</p

Activated carbon from durian shell: Preparation and characterization

Activated carbons were prepared from durian shell by chemical activation with potassium hydroxide. In order to find the optimum pore characteristics, different KOH to durian shell ratio (0.25-1.0) and activation temperature (673-923 K) was employed. The adsorption isotherm of activated carbons produced within these range of temperature and impregnation ratio is a mixture of type I and type IV isotherms. While activated carbons obtained at low chemical impregnation ratio of 0.25 were essentially microporous, with higher impregnation ratio, they become predominantly mesoporous. KOH to durian shell ratio of 0.5 and activation temperature of 773 K can be pinpointed as the optimum condition to obtain high surface area activated carbon
