CONTEXTO: Vários estudos de perda de heterozigozidade na região 9p21-p22, que abriga os genes supressores tumorais CDKN2a/p16INK4a, p19ARF e p15INK4b, têm sido realizados em uma ampla série de tumores humanos, incluindo os melanomas familiares. Perdas e ganhos em outras regiões do cromossomo 9 também têm sido observados com freqüência e podem indicar mecanismos adicionais no processo de tumorigênese dos carcinomas basocelulares da pele. OBJETIVO: Investigar o equilíbrio alélico existente na região 9p21-p22 em carcinomas basocelulares. TIPO DE ESTUDO: Análise molecular de marcadores de microssatélites em tumores e controles. LOCAL: Dois serviços de dermatologia de atendimento terciário em universidades públicas de São Paulo e o Laboratório de Genética Molecular do Câncer da Universidade Estadual de Campinas (UNICAMP), Brasil. PARTICIPANTES: Examinamos 13 casos benignos, incluindo 4 queratoses solares, 3 queratoacantomas, 3 nevos melanocíticos, 2 doenças de Bowen e 1 neurofibroma cutâneo, além de 58 tumores malignos da pele: 14 de células escamosas, 40 carcinomas basocelulares e 4 melanomas; em pacientes consecutivamente encaminhados à clínica de Dermatologia da Unicamp e que concordaram em participar do estudo. VARIÁVEIS ESTUDADAS: O tumor principal e uma porção normal de pele não-adjacente foram removidos cirurgicamente de pacientes que consecutivamente procuraram os ambulatórios de dermatologia da Universidade Estadual de Campinas (UNICAMP) e da Universidade Estadual de São Paulo (Unesp), São Paulo, por causa de lesões cutâneas. Extraímos DNA tanto de tecido tumoral como do correspondente tecido normal de cada paciente. Para amplificar regiões de repetição polimórfica de microssatélites do cromossomo 9, foram utilizados quatro pares de primers, sendo dois deles destinados à região 9p21-p22. RESULTADOS: Identificamos oito casos (20%) de desequilíbrio alélico entre os carcinomas basocelulares, sendo dois casos de perda de heterozigozidade e seis casos de instabilidade de microssatélite na região 9p21-p22. Outros marcadores também mostravam anormalidades em três destes tumores, enquanto nenhuma alteração foi detectada entre os casos benignos e nos outros tumores malignos. CONCLUSÃO: Esta dependência fenotípica sugere que existem diferenças importantes no comportamento das formas mais comuns de tumores cutâneos não-melanocíticos em relação à sua tendência para instabilidade de microssatélite no cromossomo 9. Considerando-se que os genes CDKN2a/p16INK4a, p19ARF e p15INK4b não parecem responsáveis pelas anormalidades observadas, outros genes em 9p21-p22 podem estar envolvidos na etiopatogenia e na progressão dos carcinomas basocelulares.

After thirty two years in Brazil and retired from Universidade Estadual de Campinas the author wishes to present this account, a summary of a large part of the research in synthetic methodology developed by the research groups of Albert J. Kascheres and the author at Universidade Estadual de Campinas Chemistry Institute. Contributions have been made to the area of enaminones, diazocarbonyls, cyclopropenones and azirines.

The present work aimed to study the relationship between epileptic condition and psychological activity. The purpose of this investigation was to identify cognitive complaints and affective disturbs, like depressive disorders, and to compare both with epileptic condition. Forty epileptic adolescents, aged from 13 to 19 years old were analyzed. These patients were a consecutive series of males and females attending the Neuroepilepsy Center from the Universidade Estadual de Campinas, SP, and from lower social-economic background. The methodological procedures included specific questionnaires (a open and a assertive kind), and the Zung Self-rating Depression Scale. Cognitive alterations like thinking slowness or memorizing complaints in many patients, and affective disorders like depressive disturbs in 82.5% were the basic findings. The results also showed association between frequency of seizures and depressive disturbs; and between chronicity of epileptic condition and depressive disturbs. The discussion of these data suggests a relationship of epileptic condition with psychological reactions. We concluded that it is necessary to elevate the self-concept of these depressive patients in order to reduce their psychic suffering.

El trabajo proporciona un análisis detenido de las tendencias actuales y perspectivas futuras de la familia en Brasil, con énfasis en: a) los procesos asociados a los cambios y permanencias en las unidades domésticas y familias; b) la estructura y formas de crecimiento de las unidades domésticas: familias y no-familias; c) los tipos de familias: la diversificación del modelo conyugal, el surgimiento del modelo monoparental y los determinantes próximos de estas estructuras; d) la dinámica interna de la familia: la formación y la expansión; e) las familias de mujeres; f) las familias de los hijos; g) las familias de los ancianos; h) las perspectivas de la familia.

Presents a survey of scientific production about the subject corporate governance, using the Bibliometric analysis of theses and dissertations collected in the digital libraries of the Sao Paulo State University (Unesp), Campinas State University (UNICAMP) and University of Sao Paulo (USP). Through the data collected were identified, based on Bibliometric indicators, the origin of authors, the authors more cited, the thematic area of authors, and the construction of co-citation network.

The practice of teaching is a complex, dynamic and challenging. Several obstacles are faced by educators, among them, excessive workload, classrooms with large numbers of students, reducing the support team manager etc. These experiences call into question the belief that such teachers have in their own ability to teach and motivate your students, including those with the greatest difficulties. Studies show that this belief, called self-efficacy, mediates the action of teachers and are related to the goals, persistence and motivation of teachers. The teacher self-efficacy is formed by direct experience, by observation, persuasion and psychophysiological states. The objective of the study is to identify aspects of the formation of self-efficacy teacher in-service teacher. This is a documentary study, after online search using the keywords memorials training and school as keywords, was found eight jobs at the State University of Campinas, two of which were dropped from the analysis due to not meeting the pre-established criteria. The data were organized into spreadsheets for analysis specifically designed for the study, considering the theoretical framework proposed by Bandura (1997) and Tschannen-Moran & Woolfolk Hoy (2001). The results indicate that family support throughout schooling, the role of teachers as models from basic education and teaching experiences are widely cited in memorials analyzed. These results offer from further reflections, indicating contribute to discussions on the formation and performance of teachers regarding the ability to teach, especially in the early years of elementary school

Radiotherapy is a field of medical physics, which has been going through a scientific and technological advancement, it is extreme important the professionals that work in this area continuous their study to improve the quality of service provided. For it, they should know the physical principles related as well their employment in radiotherapy. The electrons have been using in therapy of superficial tumors, because they show rapid decrease of dose in depth, they don’t expose the deeper tissues to radiation. The electron therapy has replaced the surface therapy with x-ray and mold brachytherapy, and nowadays, it represents 10 to 15% of radiotherapy treatments. This study brings the definition of physical parameters used in the dosimetry of electron beam, describes the tests for quality control of linear accelerator with a electrons beam, as well the activities realized in the Radiotherapy Division, of Hospital de Clinicas, in the Universidade Estadual of Campinas, in the Clinac 2100C machine
