Infância, experiência e tempo

Definida pelo autor César Donizetti Pereira Leite como uma pesquisa acadêmica com formato de ensaio esta obra reúne um conjunto de textos instigantes, abertos e experimentais sobre infância e educação, mas que tem neste tema apenas o ponto de partida. A intenção do autor é, mais do que comprovar alguma tese eventualmente sugerida no título da obra, mergulhar no universo infantil e retirar dele as ricas relações cultivadas pela criança com a sua realidade, com todas as suas variáveis e nuances, incluídas suas experiências com o cinema, a literatura, a passagem do tempo, os espaços, a escola. Leite não pensou a infância como algo a ser escrito ou dito, e sim vivenciado. Saborosamente fragmentado, o livro utiliza de maneira aparentemente aleatória as mais diferentes modalidades de escritura - de pequenos ensaios críticos a insights iluminadores, de poemas e citações infantis a trechos de terceiros. E faz a infância emergir com todos os seus contornos, como se ela mesma produzisse uma forma de escrever sobre ela, fabricasse uma escritura que a contornasse. É texto, mas também metatexto, e dos mais bem-sucedidos já escritos sobre o assunto.

Ensino de ciências e matemática, V: história e filosofia da ciência

Organizado por Ana Maria de Andrade Caldeira, este livro é composto por 16 capítulos escritos por professores e pós-graduandos de diversas especialidades científicas. Eles procuram problematizar questões fundamentais para o ensino de disciplinas como Biologia, Física e Matemática. Os autores apresentam estudos teóricos e empíricos com conteúdos extraídos da História e Filosofia das Ciências, tentando, ao mesmo tempo, lançar um olhar para a sala de aula, localizando e criticando conceitos que, eventualmente, são trabalhados de forma distorcida ou inadequada, com reflexos diretos e negativos na prática docente e na disseminação do conhecimento científico. Organizado de forma didática, o livro se divide em quatro grandes subáreas, cada uma delas agrupando estudos sobre diversos temas afins da Matemática, Física, Química e Biologia, respectivamente. O fio condutor da obra está na interface que todos os autores constroem entre o tema discutido e a História ou a Filosofia referentes aos quatro grandes blocos que o livro aborda. Embora denso e bastante específico, trata-se de um trabalho de leitura agradável.

Efeito do flushing sobre o desempenho reprodutivo de ovelhas Morada Nova e Santa Inês submetidas à inseminação artificial em tempo fixo

The aim of this study was to analyze the effect of flushing on the reproductive performance of Morada Nova (MN) and Santa Inês (SI) ewes submitted to fixed time artificial insemination (TAI). Twenty seven SI and 24 MN supplemented with concentrate (1% of live weight, on average), for 75 days during the breeding season. After 30 days of supplementation, ewes were synchronized with the aid of a hormonal protocol (HP) based on progesterone, eCG and cloprostenol. The estrus observation was conducted at 12, 24, 36 and 48 h after the end of HP with the aid of two ruffians. TAI was done 55 h after the end of HP. From 20 to 45 days after the beginning of the HP ewes were exposed to rams (natural breeding). The pregnancy diagnosis was evaluated 70 days after TAI. We analyzed the weight, body condition score, estrus rate, pregnancy rate and prolificacy testing the effects of race, week of supplementation and body condition score class. The weight and body conditions of ewes varied according to the week of supplementation, with higher values in the first two weeks following TAI. The estrus rate was 88.2% and 43.2% of the ewes showed estrus up to 24 hours of the end of the HP. The pregnancy rate per TAI was 31.3% and the pregnancy rate after natural breeding was 50.0%. It was observed that body condition score classes interfered in pregnancy rates. There was a higher percentage of multiple births by pregnancy by TAI than by natural breeding. It was concluded that the flushing resulted in weight gain and better body conditions ensuring the standardization of the herd for breeding season, which therefore improved reproductive performance. The HP used advanced the onset of estrus and increased prolificacy, but was inefficient in the synchronization of woolless sheep.

Morphology and expression of genes related to skeletal muscle growth in juveniles of pirarucu (Arapaima gigas, Arapaimatidae, Teleostei)

Skeletal muscle growth in the pirarucu (Arapaima gigas) is highly interesting to fish farmers because it provides information about how the mechanism in muscle mass increase, characteristic of the species, is regulated. Pirarucu has specific muscle growth that highlights the species's significance and commercial value. Current research evaluates the morphology and the growth-related gene expression in the red and white skeletal muscles of the pirarucu. Muscle samples were collected from the lateral anterior region and frozen in liquid nitrogen. Histological sections were performed and stained by HE for morphological analysis. Red and white muscle samples were used to determine MyoD, myogenin, and myostatin genes expression by Real-time Polymerase Chain Reaction. Although MyoD and myogenin were not statistically different in the two types of muscles, myostatin was significantly higher in the white rather than in the red muscle. Results show the muscle growth characteristics of the species and may be helpful for improving aquaculture management programs.

Germinação em temperatura sub-ótima de embriões de Inga vera subsp. affinis obtidos sob diferentes condições ambientais

Physiological responses like the thermal requirements for germination may be influenced during seed formation by environmental conditions such as water availability and temperature. Here we analyzed germination of embryos of Ingavera subsp. affinis from different sources in response to various temperature regimes, including calculation of degree days and accumulated rainfall during development and maturation. Embryos were taken from ripe fruits collected on trees located in São Paulo and Minas Gerais, and were analyzed as to germination, water content and dry matter content. The results showed that the origin of the embryos was related to variation in response under sub-optimal temperatures. Depending on the origin, I.vera subsp. affinis embryos were able to germinate even at low temperatures (10 to 15 ºC), with better performance attained from 20 to 25 ºC. This variation may be associated, among other factors, to environmental conditions during maturation and to the maturation stage at seed dispersal.

Análise quantitativa da deglutição orofaríngea em indivíduo gastrostomizado com Lipofuscinose Ceróide Neuronal: relato de caso

The presence of oropharyngeal dysphagia in the pediatric population with genetic diseases it is still poorly studied. The aim of this study was to analyze the oral total transit time and pharyngeal transit time, in an individual with neuronal ceroid lipofucinosis (NCL) with severe oropharyngeal dysphagia. Individual with NCL, 3 years old, 2 years with gastrostomy and no oral feeding, weighting loss, but without pulmonary complications. Oropharyngeal swallowing was studied by videofluoroscopy and it was realized a quantitative analysis using software. Changes were observed throughout the whole biomechanics of swallowing. The quantitative analysis of total oral transit time was found 45.37 seconds (default normality in children is 4 seconds) and for pharyngeal transit time was 4.53 seconds. It was found that beside the changes in the biomechanics of oropharyngeal swallowing in the case studied, an increase in total oral transit time and pharyngeal transit time was also observed, which can significantly compromise the nutritional status and pulmonary these individuals.

Tempo para acesso ao tratamento do câncer de mama no Distrito Federal, Brasil Central

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.
