Abstract: Lectin Cramoll-1,4, obtained from Cratylia mollis seeds (beans camaratu) was structurally characterized, biologically and pharmacologically, but its use as a biopharmaceutical is not well documented. The objective of this study is to propose a biopharmaceutical formulation lectin Cramoll-1,4, test their hemagglutinating properties in vitro as well as the use of gamma radiation as a continuous process of decontamination formulation. It was made of the extraction and purification Cramoll-1,4, was developed a gel formulation using Carbopol? as a vehicle, at concentrations of 50, 100, 200, 300 and 600 μg was irradiated with 60Co gamma rays in a dose of 7.549 kGy·h–1. The proposed formulation at a concentration of 300 μg produced an increase in the hemagglutinating units Cramoll-1,4 due to the synergistic effect caused by gamma radiation. Considering the diverse use of lectins, specific molecular and structural factors, as well as changes resulting from its formulation, concentration, irradiation and route of administration is of utmost importance to continue the studies in vitro, for subsequent application in vivo to characterize the physiological and molecular processes involved in the response and cellular effects.

Abstract: A repelência de inseticidas botanicos tem se destacado como uma tática promissora no controle alternativo de pragas agrícolas e urbanas, podendo ser um dos componentes do manejo integrado de pragas. Objetivou-se com este trabalho identificar a repelência de inseticidas botanicos sobre fêmeas ápteras de Aphis gossypii Glover. Testes com chance de escolha foram realizados com discos de folha de algodoeiro, imersos nas caldas dos inseticidas e testemunha (água destilada com DMSO a 2%). Utilizou-se azadirachtina (0,075%) e os óleos essenciais de Piper hispidinervum CDC, P. aduncum L., Cymbopogon winterianus (L.), C. citratus (D.C.) Stapf, Foeniculum vulgare Mill, Syzygium aromaticum (L.) Merrill e Perry, Cinnamomum zeylanicum Blume, Schinus terebinthifolius Raddi e Chenopodium ambrosioides L. na concentra o de 0,05%. C. citratus, C. winterianus, P. aduncum, S. terebinthifolius, azadirachtina e C. zeylanicum apresentaram os maiores percentuais de repelência, 100; 84; 66,67; 64; 60,87 e 48% respectivamente e reduziram a produ o de ninfas em 100; 92; 42,9; 87,5; 80,65 e 89,74%, apresentando resultados significativos pelo teste do χ2 ao nível de 10% de probabilidade. Nos testes com F. vulgare (χ2 = 3,66, P = 0,05) as fêmeas de A. gossypii foram atraídas significativamente para os discos tratados e ocorreu um aumento na produ o de ninfas nos resultados obtidos para F. vulgare (χ2 = 5,87, P = 0,02) e C. ambrosioides (χ2 = 14,31, P = 0,001). The repellence of botanical insecticides has emerged as a promising technique in the alternative control of urban and agricultural pests, being seen as one component of integrated pest management. The aim of this work was to identify the repellence of botanical insecticides on apterous females of Aphis gossypii Glover. Random-choice tests were carried out with discs from the leaves of cotton plants immersed in insecticide solution and in a control (distilled water with 2% DMSO). Azadirachtin was used (0.075%) and the essential oils of Piper hispidinervum CDC, P. aduncum L., Cymbopogon winterianus (L.), C. citratus (DC) Stapf, Foeniculum vulgare Mill, Syzygium aromaticum (L.) Merrill and Perry, Cinnamomum zeylanicum Blume, Schinus terebinthifolius Raddi and Chenopodium ambrosioides L. at a concentration of 0.05%. C. citratus, C. winterianus, P. aduncum, S. terebinthifolius, azadirachtin and C. zeylanicum showed the highest percentage of repellence, 100, 84, 66.67, 64, 60.87 and 48% respectively, and reduced nymph production by 100, 92, 42.9, 87.5, 80.65 and 89, 74%, with significant results from the χ2 test at 10% probabilit

Abstract: ceraeochrysa claveri navás (neuroptera: chrysopidae) is a predator found in several agricultural ecosystems and it preys on small and soft body insects. its high reproductive potential and forage capacity makes it able of preying eggs and larvae of plutella xylostella (l.) (lepidoptera: plutellidae) internally hidden on cabbage head, where other natural enemies usually do not reach. these characteristics are important when choosing this predator to be used within biological control programs. this search evaluated the c. claveri development, reproduction, as well as the consumption of p. xylostella eggs and larvae under laboratory conditions. therefore, it was evaluated the following diets: 1) eggs; 2) larvae of second ínstar; 3) eggs + larvae of second ínstar. the development and the viability of the immature forms of c. claveri were better in the diets containing eggs of p. xylostella. also, the egg laying and adult longevity were greater with these diets, independently of the larvae presence. however, the diet type did not affect the sexual rate and the weight of the larvae after eight days of living. on average, each c. claveri larva was able of preying 1611 eggs or 135 second-ínstar larvae of p. xylostella during its development. the predator was able to increase its population 218 times after 42 days, feeding exclusively on p. xylostella eggs. based on these results, this predator presents a great potential of being used within biological control programs of p. xylostella.

Abstract: brazilian football, as a social phenomenon, had been subordinated to the substantive reason based on values and tradition. however, this sport has become a business due to its attractiveness as a source of wealth. when sport organizations incoporate the logic of the market, the consequence is the adoption of elements from the business world in the administration of these organizations. managerial concepts and practices become present, changing the managements discouise as well as the basis for their legitimation in their specific context. thus, the emergence of a new logic of reference produces new actors, new procedures and categories that were exclusive to the environment of entrepreneurial organizations, like goods, customers, efficiency, results and competitiveness. when players are submitted to the logic of the market, they become goods, supporters become consumers, the game becomes a financial asset and the football is seen as a great business. relations are based on impersonality, strategies of control are developed since they assure the achievement of objectives, as well as modernizing market actions, and the legitimate management is the one wich is based on professionalism. this study contributes to the discussion on the scenario of social change wich includes not only sport organizations but also arts, cinema and even public spaces, with the purpose of trying to provide future reflexions.

Abstract: Ananas ananassoides é uma planta perene com hábito de crescimento herbáceo e que tem enorme potencial paisagístico porque apresenta flores e brácteas com colora o exuberante e folhas com margens espinescentes que est o distribuídas em roseta. O objetivo deste experimento foi o de avaliar as características germinativas e o efeito de tratamentos pré-germinativos nas sementes da espécie. Primeiro, em um delineamento inteiramente casualizado, foram investigados seis tratamentos em quatro repeti es de 25 sementes. Ostratamentos constaram da imers o em água destilada à temperatura ambiente (25 ± 1,5°C) durante 24, 48 e 72h, imers o em água quente a 90°C durante 2 min. e imers o em ácido sulfúrico p.a. durante 2 min. e com posterior lavagem em água corrente por 24h que foram comparados com um controle. Depois de quatro meses de armazenamento, sementesintactas (controle) foram comparadas com sementes imersas em água a 90°C por 2 min. Assim, a maior porcentagem de germina o (92%) foi obtida com sementes recém-colhidas e imersas em água a 90oC durante 2 min., mas o armazenamento por quatro meses melhorou a porcentagem de germina o (G ≥ 96,0%). Os tempos médios de germina o n o diferiram entre as sementes recém-colhidas (de 21,0 a 26,8 dias) e as armazenadas (entre 18,4 e 19,5 dias). A germina o das sementes recém-colhidas e armazenadas foi lenta e distribuída ao longo do tempo experimental. Ananas ananassoides is a perennial plant with ornamental potential because of flowers and bracts with exuberant colors and herbaceous development where the leaves have spiny margins that are distributed in rosettes. The objective of this experiment with six completely randomized treatments and four replicates of 25 seeds was to evaluate the effects of seed soaking into distilled water at environmental temperature (25 ± 1.5°C) for 24, 48, and 72h; seed soaking into water at 90°C for 2 minutes; seed soaking into sulfuric acid p.a. for 2 minutes followed by tap water washing for 24h, and the control. Thereafter, 4-month-old seeds were immersed into water at 90°C for 2 minutes and compared to the intact seeds (control). Initially, the highest percentage of germination (G=92%) was evaluated in newly collected seeds that were immersed in water at 90°C for 2 minutes. No increases in the percentage of seed germination were detected by seed soaking into water or sulfuric acid in comparison to the seeds that were immersed in water at 90°C for 2 minutes. However, the percentage of germination was higher than 96% when the seeds were stored for four months. No difference in the mean
