O presente trabalho é resultado de uma pesquisa de cunho quantitativo e qualitativo, que teve como objetivo principal mapear a produção do GT 23 Gênero, Sexualidade e Educação da ANPED, Associação Nacional de Pesquisa e Pós- Graduação em Educação, no período de 2004 a 2009. O GT 23 iniciou suas atividades em 2004, ainda como grupo de estudo. Sua produção apresentada nas reuniões anuais consta de trabalhos apresentados, pôsteres, mini-cursos e trabalhos encomendados. Na perspectiva qualitativa, foram analisados apenas os trabalhos apresentados, que compõem uma amostra de 77 trabalhos. Esta análise deseja perceber as temáticas tratadas nos trabalhos, identificar os/as agentes que produzem nesse domínio e as instituições a que estão vinculados/as, e ainda enxergar o quanto e como a temática das políticas públicas em educação para a promoção da igualdade de gênero é abordada nesse conjunto de trabalhos. A análise dos dados permitiu reconhecer que embora as questões de gênero e suas interseções com educação e sexualidade sejam ainda alvo do interesse de pesquisadoras, no universo do GT 23 é crescente o número de pesquisadores que se dispõem a tratar o tema, embora estes estejam mais concentrados na intersecção sexualidade e educação. Além disso, constatou-se que a temática das políticas públicas em educação no que diz respeito à promoção da igualdade de gênero é pouco pesquisada, sendo maior o interesse pelas políticas públicas que dizem respeito à sexualidade e educação.

Periodontal disease is a chronic inflammatory condition primarily caused by bacteria in dental biofilm, which interact with the host, thus determining the nature of the resulting disease. Despite the wide knowledge about the pathogenesis of these diseases, the exact composition of the T cell profile during the active phase of the disease (Th1, Th2 or Th17) remains unknown. This study aimed to evaluate by immunohistochemical expression, the presence of the markers (IL-17, IL-23 and RORγt), involved in Th17 response in clinically healthy gingiva cases (n = 32), biofilm-induced gingivitis (n = 30), chronic periodontitis (n = 32) and aggressive periodontitis (n = 25), in order to analyze if the expression and/or distribution of these molecules in lymphocytes and macrophages, present in the inflammatory infiltrate of periodontal tissue, influences the tissue destruction observed in these diseases. The morphological analysis of cases was performed which assessed the intensity of the inflammatory infiltrate in mild, moderate and intense. For each case, in the area with the most representative immunostaining, 5 fields were chosen and analyzed, both for the intensity of the inflammatory infiltrate as for the quantity of immunostained cells, based on predetermined scores: score 0 (absence of inflammatory infiltrate/immunostaining), score 1 (the infiltrate/immunostaining covered less than 25% of the field area), score 2 (the infiltrate/immunostaining occupied between 25 and 50%) and score 3 (infiltrate/immunostaining present in over 50% of the field area). From this, a median was generated representing each case. The intensity of the inflammatory infiltrate correlated with the disease progression, in other words, it was crescent from clinically healthy gingiva to aggressive periodontitis (P <0.001). It was detected the presence of IL-17, IL-23 and RORγt in most of the evaluated cases and the number of immunostained cells correlated with the intensity of the inflammatory infiltrate (P <0.001) and with the clinical parameters analyzed (P <0.001), showing a positive correlation, mainly moderate. Aggressive periodontitis showed a higher percentage of immunostaining for all markers in relation to other clinical conditions assessed, suggesting a possible association of these markers with the progression of this disease, in which the higher the loss of periodontal support, the greater the amount of inflammatory infiltrate and larger the number of immunostained cells.

Este estudio presenta un análisis exploratorio sobre la correlación entre la fortaleza institucional, las condiciones de paz, y el emprendimiento en una muestra de 23 departamentos en Colombia usando datos de 2014. Para llevar a cabo este objetivo se propusieron y construyeron tres índices siguiendo definiciones conceptuales seminales o estándares de evaluación internacional, a saber: 1) El Índice de Fortaleza Institucional, 2) El Índice de Construcción de Paz (construido a partir del índice de paz negativa y el índice de paz positiva) y 3) El Índice de Emprendimiento Productivo. Los resultados no muestran una correlación significativa entre todos los tres índices. Por un lado, existe una correlación significativa (p<0.05) entre los índices de fortaleza institucional y emprendimiento productivo. Por otro lado, existen correlaciones negativas no significativas entre los índices de paz positiva y fortaleza institucional, emprendimiento productivo y paz positiva y emprendimiento productivo y construcción de paz. En un segundo acercamiento, la población de los departamentos fue la variable con mayor número de correlaciones significativas (p<0.01) entre variables relacionadas con emprendimiento productivo, empleo, producto interno bruto, sofisticación industrial, innovación (patentes) y crimen. Finalmente, se discuten las conclusiones y las futuras investigaciones.

Realizada uma intervenção educativa com o objetivo de reduzir o número de famílias que consomem água sem tratamento e suas consequências na população da ESF "Elis Renys dos Santos”, do município de Dourados, estado de Mato Grosso do Sul. A amostra do estudo foram 120 pessoas, entre os 20 e 65 anos de idade de nossa comunidade. Os dados primários foram obtidos com a aplicação de um questionário, de acordo as principais necessidades de conhecimentos sobre o tema, desenvolvendo um programa educativo. Posteriormente aplicamos novamente o questionário, observando-se um aumento significativo dos conhecimentos sobre a importância de se tratar a água de consumo e a prevenção de parasitoses intestinais. Para a análise estatística da informação foi usado o cálculo porcentual. Foi possível observar que o nível de conhecimento inicial sobre parasitoses intestinais era baixo e com a intervenção educativa isto mudou significativamente de maneira positiva.

OBJECTIVE: To investigate the clinical and genetic characteristics of familial partial epilepsies. METHOD: Family history of seizures was questioned in all patients followed in our epilepsy clinics, from October 1997 to December 1998. Those with positive family history were further investigated and detailed pedigrees were obtained. All possibly affected individuals available underwent clinical evaluation. Seizures and epilepsy syndromes were classified according to the ILAE recommendations. Whenever possible, EEG and MRI were performed. RESULTS: Positive family history was identified in 32 unrelated patients. A total of 213 possibly affected individuals were identified, 161 of whom have been evaluated. The number of affected subjects per family ranged from two to 23. Temporal lobe epilepsy (TLE) was identified in 22 families (68%), frontal lobe epilepsy in one family (3%), partial epilepsy with centrotemporal spikes in five families (15%), and other benign partial epilepsies of childhood in four families (12%). Most of the affected individuals in the TLE families (69%) had clinical and/or EEG characteristics of typical TLE. However, the severity of epilepsy was variable, with 76% of patients with spontaneous seizure remission or good control with medication and 24% with refractory seizures, including 7 patients that underwent surgical treatment. In the other 10 families, we identified 39 possibly affected subjects, 23 of whom were evaluated. All had good seizure control (with or without medication) except for one patient with frontal lobe epilepsy. Pedigree analysis suggested autosomal dominant inheritance with incomplete penetrance in all families. CONCLUSION: Family history of seizures is frequent among patients with partial epilepsies. The majority of our families had TLE and its expression was not different from that observed in sporadic cases. The identification of genes involved in partial epilepsies may be usefull in classification of syndromes, to stablish prognosis and optimal treatment.

Chromosome numbers of 11 South-Brazilian species of Adesmia were determined. The cytological preparations were obtained by squashing cells of root tips, using the acetic-orcein method. The chromosome number for all the species studied was 2n=20, excepting A. incana var. incana with 2n=ca.40. The counts are new for nine species, and the other two agree with the literature. It is suggested x=10 as the basic number for the genus. Up to the present only four species were cited as polyploid.

The study assessed phloem canal development and ultra-structure in shoot apices of Spondias dulcis G. Forst., phloematic canal ultra-structure in shoot apices of Tapirira guianensis Aubl., and floral canal ultra-structure and development and fruit canal ultra-structure of the latter specie. The flower and fruit canals of Anacardium humile St.Hil. were also studied ultra-structurally. The canals in shoot apices of S. dulcis show schizo-lysigenous formation and the floral canals of T. guianensis show schizogenous development. Epithelial cells of S. dulcis and T. guianensis canals have rough endoplasmic reticulum, free ribosomes, elongated plastids of several shapes with osmiophilic inclusions and dictyosomes with production of vesicles. Such organelles participate in the secretion of a heterogeneous exudate, which is comprised of hydrophilic and lipophilic substances. The epithelial cells of the fruit of A. humile present elongated plastids with circular membrane system, which are involved in the synthesis of lipophilic substances. The results of the ultra-structural analyses of the epithelial cells corroborate the results previously obtained in a histochemical study. In the histochemical study, lipophilic and hydrophilic substances were identified in the canals of T. guinanensis and S. dulcis and only lipophilic substances were identified in the canals of A. humile. Based on the ultrastructural aspects of the secretory canals of T. guianensis and S. dulcis we concluded that the plastids of the epithelial cells of the two species are different although they produce secretion of similar composition. A new record for the family is the presence of a great number of circular plastids in epithelial cells of the fruit of Anacardium humile. The pattern found in the secretory canals of the studied species is the ecrine type of secretion release.

A cytotaxonomic analysis of species of Acosmium Schott e Leptolobium Vogel was carried out, by determining their chromosome numbers. The three species of Acosmium and five species of Leptolobium (representing 50% of the genus) were studied from seeds obtained from different regions of Brazil. Chromosome counts were new for all Acosmium species and for four Leptolobium species. For Acosmium cardenasii, 2n = 18 was constantly observed, while occurring at the same meristem were found 2n = 18, 24 e 32 in A. diffusissimum and 2n = 18 e 32 in A. lentiscifolium. For Leptolobium, all studied species had 2n = 18, confirming a previous count for L. dasycarpum. The results showed that chromosome numbers of Acosmium and Leptolobium species are homogeneous, confirming the basic number x = 9 for both genera. Therefore, chromosome numbers do not provide a useful taxonomic character distinguishing Acosmium from Leptolobium.

This aim of this work was to carry out an epidemiological study on acetabular fractures in the city of Campinas and surrounds, in view of the few published papers on this subject. Medical files with a diagnosis of acetabular fracture between the years 2004 and 2008 that were made available by the Medical Archiving Service of Hospital das Clínicas, State University of Campinas (UNICAMP) were analyzed by six observers. Data on patients' ages, sex, side affected by the fracture, mechanism of injury, material used for synthesis, complications of the operation, associated fractures, length of hospitalization before and after the surgery, time of total internment and number of physiotherapy sessions before and after the surgery were gathered. It was observed in this population that the left side was more affected; the mechanism of injury that most often caused this type of fracture was automobile accidents; injuries to the sciatic nerve were the commonest surgical complications; and the synthesis material most used was reconstruction plates.
