A importância da dança e das artes no geral para a espécie humana é evidenciada pela sua marcante presença em todas as sociedades, primitivas ou civilizadas, aparecendo na maioria de suas atividades.A dança faz parte do mundo da comunicação não verbal, expressando, transmitindo muitas informações e apresentando-se com diferentes significados, geralmente associados à comunicação e à interação entre indivíduos. Como movimento ordenado e rítmico,a dança pode ter por base nossas manifestações biológicas, podendo ser considerada como um evento inato e hereditário.Nesse contexto, apresentou-se uma revisão bibliográficaque trata da dança sob uma perspectiva biológica e evolutiva,caracterizando-a nos processos de comunicação e socialização humana. O panorama traçado baseou-se em diferentes áreas de estudo, tentando organizar as ideias e proposições de diferentes autores a respeito deste tema, ainda não tão discutido e nem tão difundido na literatura. Foram consultadas diferentes áreas, em especial a Etologia e a Psicologia Evolucionista, que fazem uma abordagem evolutiva de aspectos da natureza humana.Não foi possível encontrar na literatura uma definição única de dança que a contemplasse da maneira com a qual se gostaria de trabalhar nesta pesquisa.Por isso, foi proposta uma conceituação para as discussões posteriores, tratando a dança sob os seguintes aspectos: comportamento onipresente nos grupos humanos, desde tempos bastante remotos;comportamento significativo para os grupos que a apresentam, sob diferentes aspectos;comportamento que necessita de especialização e desenvolvimento cognitivo para sua realização; comportamento atrelado à sensação de prazer; comportamento que representa um processo de comunicação altamente complexo e especializado; comportamentoritmado, que possa ser tratado num complexo de musicalidade, que envolva a dança...

A utilização de programas computacionais específicos como ferramentas para análise estatística em identificação humana e de vínculos genéticos tem se tornado imprescindível, principalmente em casos de maior complexidade ou em grande escala. A análise de casos em que há genealogia incompleta gera resultados inconclusivos tornado os cálculos estatísticos mais laboriosos, consumindo tempo e pessoal qualificado. Os objetivos desse estudo são: o estudo simulado de casos reais de identificação humana e vínculos genéticos em situações especiais (meios irmãos na ausência dos pais, reconstrução), utilizando programas computacionais livres de cálculos estatísticos como ferramenta; a verificação do melhor programa livre de análise estatística disponível para utilização nos centros públicos brasileiros; e o levantamento estatístico dos casos reais brasileiros (vínculos genéticos, negatória, exclusão) para se obter uma visão da realidade brasileira em relação às suas relações familiares. Os principais métodos foram: análise das informações contidas nas fichas de registro e documentos anexados aos exames de vínculo genético dos participantes; e inserção nos softwares dos resultados de perfis genéticos obtidos de diferentes casos, de acordo com as especificações de uso. A amostra populacional dos casos analisados nesse trabalho incluiu 3.871 indivíduos. Em relação aos casos reais brasileiros, o exame de vínculo genético mais requisitado foi o de paternidade tipo trio; 68% dos casos incluíram o suposto pai como o pai biológico e 27% dos supostos pais estavam registrados na certidão de nascimento do filho e requisitaram o exame de paternidade para confirmá-la. A taxa de mutação encontrada variou de 0,4 a 2 x 10-3 per locus per gamete per generation. Após os estudos simulados... (Resumo completo, clicar acesso eletrônico abaixo)

There are cassava varieties that present compounds as carotenoids, beta-carotene, lycopene and minerals important for human and animal health. The present study evaluated the antioxidant activity of the white, yellow and pinkish varieties of Manihot esculenta, by mean of the DPPH test and by the ferrous ion-chelating activity. Furthermore, the total phenols, carotenoids, beta-carotene, lycopene and zinc contents were also determined. Utilizing the DPPH test it was possible to find that extracts of boiled samples presented higher antioxidant activity (89.53% - pinkish) in comparison to the fresh samples (1.97% - white). For the ferrous ion-chelating test, the highest activity was found for the boiled pinkish variety extract (63.43%) and the lowest was for fresh yellow extract (17.34%) the white sample did not present activity. The highest concentration of total phenols and zinc content was obtained for the boiled pinkish variety extract 136.12 mg EAG/g of extract and 0,811ppm, respectively, in the concentration of 1000 µg/mL. The pinkish variety presented also higher quantity of pigments, including carotenoid (29.40 µg/g), beta-carotene (9.14 µg/100g) and lycopene (68.92%). According to the results obtained in this study it was possible to conclude that the yellow and pinkish varieties of M. esculenta present quantity of phenolic compounds and minerals sufficient to attribute the antioxidant activity and may thus contribute to reduce oxidative damage and be used as nutraceuticals or directly ingested in the diet to maintain good health.

This work aims to present through a literature review, the main features and employability of the natural sweetener xylitol. This sweetener has low calorie, can be used by people with diabetes and is an excellent substitute for sucrose and other sweeteners. Xylitol can be separated from many fruits and vegetables through the reduction of xylose, which can occur by chemical or biotechnological synthesis. In addition to their use in the food industry, xylitol also has great value beneficial to human health by acting as anticariogenic, preventing and treating diseases such as acute otitis media and hemolytic anemia, as well as being growth inhibitor of various bacteria

In this article are defended the possibility and the necessity of the teaching of the reception of art works in school education. Firstly, some relations between art and the development of both the human species and the individual are analysed in Georg Lukács and Lev Vygotsky’s works. In order to put in question the old assumption that opposes education and instruction, the discussion made by Gramsci on the grammatical teaching of Latin and Greek in the traditional school education is explored. In the article is concluded its path analysing the intentional and systematic formation of the reception of art works provided by school education based on Aleksei N. Leontiev’s works on the appropriation process of culture by the individual.

The paper demonstrates the magnitude of the constitutional statement of the dignity of the human person subscribed to the Federal Constitution of 1988 as a fundamental principle. Next, it brings reports on quality of life of residents of Vila Esperança, in the municipality of Cubatão (SP), from an ethnographic approach, descriptive and photographic documentation. We could conclude that the Brazilian legal system is organized hierarchically, so the Principle of Human Dignity cannot be disregard. The vital guarantee of a minimum vital floor is essential for poor people to expand the possibilities for the full exercise of human dignity.

The main objective of this work was to mount and test an experimental model to measure the hydraulic conductance of ex vivo dentin. Seventeen healthy third molars, with indication of extraction of healthy donors aged between 15 and 30 years were obtained by informed consent. After cleaning them, disinfecting them, including them in resin epoxy and cutting them, there were 17 samples of dentin, corresponding to a disk of resin with a coronal section of tooth showing the dentin exposed on both sides of it. Three machines to measure the hydraulic conductance of the dentin were assembled according to the description of the model of Pashley. Samples were installed in a Chamber of diffusion, connected by using silicone tubes to a graduated transfer pipette and a 20cm water column. Through the displacement of a bubble of water in the inside of the pipette, the hydraulic conductance of each sample was measured 3 times on the 14th, 21st, 28th and 35th day post extraction. The data were tabulated and analyzed statistically. There is no SS difference in the rate of flow of a measured sample in the three machines (p=0.5937). There is no SS difference in measurements of the hydraulic conductance of 13 samples of human dentin measured in days 14, 21, 28 and 35 postextraction (p=0.0704). It is possible to mount an experimental model to study the hydraulic conductance of dentin ex vivo, based on the model of Pashley. The model seems to be reliable, but more research is needed in order to validate its reliability.

The aim of this study was to compare the hydraulic conductance in human dentin disks, where 1, 2 or 3 layers of adhesive Single Bond 2(SB2) and Single Bond Universal(SBU) were applied. 84 1 mm. thick(+/- 0.1 mm.) dentin disks were fabricated. Samples were divided into 7 groups (n = 12) Control (without adhesive), A1: one layer of SB2, A2: two layers SB2, A3: three layers SB2, B1: one layer SBU, B2: two layers of SBU, B3: three layers of SBU. The results as averages for the hydraulic conductance of each separate group were: Control (0.0363), A1 (0.0206), A2 (0.0070), A3 (0.0061), B1 (0.0161), B2 (0.0062), B3(0.0056) expressed µl/min.cm2. There is statistically significant difference CH, between the control group and those samples that one coat was applied (p = 0.000) and also between the application of one and two layers (p = 0.000). No difference between the two adhesives (p = 0.434). Summary Key words: Dentin, conductance, difussion adhesive layers.

The clinical records correspond to a set of documents where all information of the patient is stored. When properly confectioned and filed by the dentist, it may serve as a tool for success in dental expertise. The aim of this paper is to present the importance of proper confection of dental records in human identification by means the presentation of a case of identification, occurred in a São Paulo state city. The notes present in the dental records of the alleged victim were very poor, even with a contradiction. However, having endodontic treatment been performed, the comparative analysis between the radiographs of the skull of the victim (postmortem) and the endodontic treatment of tooth 22 (antemortem) permitted to observe total coincidence between the details of such treatment, and anatomical features present in other dental elements. These important parameters of comparison indicated that the body was of the suspect and, due to the number of coincidences, it could not belong to another individual. Nevertheless, the clinical documentation provided was deficient, and presented contradictory data. Because of its fundamental importance for human identification, it is essential that dental professionals take the necessary care to ensure its proper confection and custody, seeking to make the clinical records also an efficient instrument of consultation in identification cases.
