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.

Parasitism constitutes one of the main problems that affect livestock. Commercial acaricides have been used to control tick, but these chemicals have been responsible for the development of drug resistance and residues in the environment. Changes in the concept of production determined the search for natural measures, which guarantees animal sanity along with safety of the produced food. This assay had as objective to evaluate the citronella oil and neem oil in the control of bovine ticks. By the technique of adult ticks immersion, 280 ticks were evaluated, distributed in equal number throughout four treatments: negative control group, positive control (ivermectin), neem oil and citronella oil. It was analyzed the mortality index, estimated reproduction, product efficiency, index of eggs production and the hatchability rate. The efficiency of the product was verified by the mortality index just for the positive control group (100%) and citronella oil (97.14%). Also, the citronella oil inhibited the eclosion of eggs in 100%. The other treatments did not presented the minimum eclosion inhibition level of 95%. Under the conditions of the present assay citronella oil was efficient against Rhipicephalus (Boophilus) microplus. This result was not observed in relation to the neem oil.

Parasitic diseases constitute one of the main problems affecting livestock; however the use of chemical medicaments provides drug resistance residues in animal and environmental contamination. Changes in production concepts require that food must be produced in hygienic conditions, per healthy animals and that are not eliminating antibiotic residues, pesticides or other drugs. This scenario has favored organic production and the use of medicinal plants. For the control of endoparasites, several studies have published the benefits of Azadirachta indica A. Juss., Punica granatum Linn., Musa sp., Operculina hamiltonii G. DON., propolis, among others. However, despite the existence in- vitro studies that demonstrate the pharmacological properties of phytotherapics, there is still need for clinical trials to determine dosage and its effects in- vivo. Investigations of new bioactive natural substances can be of great value for the control of animal health and food safety, which is particularly important for organic production systems in which the use of chemical drugs is a limiting factor for certification.

Se historicamente a educação escolar no Brasil foi marcada por um profundo corte elitista, o processo de democratização do ensino apresentou incontestáveis avanços desde a Constituição de 1988. A caminhada pela universalização, no entanto, não se deu à margem de suas heranças históricas, bem como novas fronteiras surgiram para o desafio da educação emancipatória. Esta obra reúne 17 ensaios que debatem os dilemas existentes no cotidiano da sala de aula. Divididos em três partes - " Educação, culturas realidade social", "Políticas educacionais" e "A escola" -, os textos coligidos abordam temas variados relacionados à prática escolar, como cidadania, políticas afirmativas e gestão administrativa, e compõem um cenário contemporâneo dos principais desafios colocados para a educação de nosso tempo.

Os Medicamentos Isentos de Prescrição (MIPs) são de venda livre que têm como propósito tratar sintomas e distúrbios menores, sendo responsáveis pela movimentação de bilhões de dólares a cada ano mundialmente. É permitida a veiculação de propagandas direta ao consumidor, não sendo obrigatória a apresentação da prescrição. A disponibilidade e o consumo de MIPs podem impactar a saúde, economia e a promoção do uso racional de medicamentos, portanto se faz necessário compreender o comportamento e as motivações dos consumidores pelos MIPs e a prática da automedicação. Para tanto, conduziu-se um estudo entre março e junho de 2014 por meio de entrevistas com perguntas abertas referentes a classes terapêuticas adquiridas para automedicação, frequência com que os consumidores compraram MIPs e se automedicaram, os problemas de saúde que os motivaram a se automedicarem e a comprarem MIPs e à prática da automedicação. Foram entrevistados 47 consumidores entre 18 e 70 anos residentes em Araraquara/SP. A indicação familiar é o fator de influência mais recorrente (14), seguida pela indicação do balconista da drogaria (11) e amigos (6). A classe de MIPs mais consumida pelos entrevistados é a de analgésicos, que está relacionada com a ocorrência de dores de cabeça e musculares, sendo que a compra de MIPs ocorre, no mínimo, uma vez por mês. As motivações para a compra são principalmente o preço (33) seguido da marca (30). A automedicação ocorre também para o alívio de dores e a maioria alegou saber o conceito da automedicação porém, ainda assim, afirmou administrar por conta própria medicamentos MIPs e/ou sujeitos a prescrições, sem orientação de um profissional de saúde.

This paper provides an overview of the reality of Colonial Corps created in the early twentieth century, in São Paulo, based on a cut of the genesis of the municipality of Peixoto Hawk when he was one of the centers for the accommodation of European immigrants; well as in parallel to the phase coronelismo intensified in the area. From this historical assumption, following a brief contemporary approach, already in the XXI century, in order to provoke a debate that can aggregate relevant contribution to the strategic purposes of the locality, including inserting the new reality imposed by the deployment of the Aerospace Hub in the town, represented by installation of Empresa Brasileira de Aeronautica S / A - Embraer. It takes into account, thus the set of their social and cultural phenomena occurred and developed over time (diachronic); based on an analysis for educational planning, particularly in developing and implementing public policies and projects to new propositions for improvement Local education at different levels.

The polemical discussion between orthodontic therapeutic and surgical approaches with relation to borderline cases receives a new impulse with the emergence of temporary anchorage devices. This branch of Orthodontics has brought new treatment perspectives, but it has still been applied empirically, while the various factors involved in determining and conducting the treatment planning are neglected. The objective of the present study is to identify the several factors to be considered in both forms of treatment in order to provide the orthodontist with information that may contribute for the correct decision.

Endodontic sealer residues on dentinal surface have negative effects on adhesion of adhesives system and/or can cause discoloration of the dental crown. Objective: To evaluate the efficacy of 95% ethanol in removal of residues of epoxy-based (AH Plus), methacrylate-based (Epiphany SE) or calcium-based (Sealapex) sealers on dentinal surface. Material and methods: Thirty-two bovine incisor dental crown fragments (0.5 mm x 0.5 mm) were treated with 17% EDTA and 2.5% NaOCl. The specimens were divided into three experimental groups (n = 10): G1 (AH Plus), G2 (Epiphany SE) and G3 (Sealapex). In each group was applied a coating of one endodontic sealer type and were left undisturbed for 5 minutes. After this period, the specimens were cleaned with 95% ethanol. The control group was composed by two specimens that did not receive any sealer or cleaning treatment. The sealer residues persistence after cleaning with 95% ethanol was evaluated by scanning electron microscopy (x500) and a score system was applied. Data obtained were analyzed by Kruskal-Wallis and Dunn tests (α = 5%). Results: Moderate amount of endodontic sealer residues were observed in all groups, regardless of the endodontic sealer compositions. G1, G2 and G3 presented similar amount of sealer residues on dentinal surface after cleaning with 95% ethanol (p > 0.05). Conclusion: 95% ethanol was inefficiency to remove completely AH Plus, Epiphany SE and Sealapex residues of sealer-contaminated dentin.

Introduction: Oral health can affect quality of life, and the OHIP-14 index (Oral Health Impact Profile) is useful for evaluating this impact. Objective: to investigate the impact of oral health conditions on the quality of life of patients over 50 years, assessing, initially, the consistency of the short form of the Oral Health Impact Profile index (OHIP-14). Material and method: A cross-sectional study was performed among 149 patients of two public institutions for routine dental (UNESP) and medical practice (Municipal). They were interviewed using the OHIP-14 formulary, assessing its internal consistency (Cronbach´s alpha coefficient) and the OHIP-mean (additive method). The patients were distributed according to sex, age, and education level. The comparisons of interest were made using Student´s t test at a 5% level of significance. Result: A total of consecutive patients (n = 149) participated of this study (87% response rate). Cronbach´s alpha coefficient was 0.78, denoting a good consistency of the OHIP index. The OHIP mean was 4.98. The most prevalently affected OHIP domains were dimensions of physical pain: painful aching (11.40%) and uncomfortable eating foods (21.50%). There was non-significant difference (p > 0.05) between the mean OHIP value in relation to each of gender, age, and education level. Conclusion: The OHIP-14 is a reliable instrument of assessing oral health-related quality of life, and among patients under routine practice, it was found a low impact of oral conditions on their quality of life in the studied institutions (UNESP and Municipal).
