Estretégias de acasalamento e qualidade do espermatóforo em heliconius (Lepidoptera, Nymphalidae)

Butterflies are insects known, in a variety of environments and for easy visual identification. The adult form may be frequently found in flowers looking for nectar. However, for many species of Heliconius (Lepidoptera, Nymphalidae) to visit the flower also represents the collecting of pollen, an important source of protein for adults. The protein obtained from the pollen allows the maintenance of physiological processes that increase the performance of the individual, promoting greater longevity and egg production. For males, proteins can also be part in your investment in reproductive success and fitness of offspring through a nutritional contribution that is transferred to the female in the act of mating as a nuptial present. It is known that this protein contains essential to the performance of the female oviposition, however the proportion of content and specific importance to the monogamous and polygamous species is not known yet. Whereas the species studied in this work have different patterns of mating in the strategy was to verify a significant difference in the quality of the spermatophore, and H. erato and H. melpomene, on the amount of protein present in this structure, indicating a difference in investment between the male reproductive strategies

Filogenia molecular de fungos gasteroides das ordens Phallales e Geastrales (Phallomycetidae)

Gasteroids fungi are characterized by the basidiospores maturation inside the basidioma, from which spores liberation occurs in a passive manner. These fungi were once seen as a well definite class of Basidiomycota, but nowadays they are considered an artificial assemblage, because the organisms have independent evolutionary histories forming a polyphyletic group with a vast morphological variety. Despite their diversity, studies with this group in the tropics are incipient, and the phylogenetic relationships of the species from temperate climate remain unknown. Thus, this work aimed to elucidate the phylogenetic relationships of gasteroids fungi from the Geastrales and Phallales orders, with the inclusion of tropical and temperate species, and with these analyses suggest a systematic position of species like Aseroë floriformis and Phallus roseus, as well as to verify if the lignicolous habit can indicate parental relationship in the Geastrum genus. For this, basidiomata were collected at Atlantic rain forest areas, during the rainy season, and the specimen identification followed specific literature for gasteroid fungi. The phylogenetic analyses were performed with Maximum Parsimony and Bayesian Analysis, making use of RPB2 and 28S nuclear genes and atp6 mitochondrial gene. It could be observed on the Phallales dendogram, that Aseroë floriformis did not cluster with A. rubra, and that it has an anterior divergence from all others species of the family Clathraceae used in this analysis, assuming a basal position in the clade. Phallus roseus, which once was recognized as Itajahya, has previous divergence from the group formed by Phallus species. At the Geastrales dendogram, in the group corresponding to Geastrum genus, it could be observed that species with lignicolous habitat clustered in a clade with high support values. So, the results suggest the creation of a new genus to accommodate A. floriformis, and the revalidation of Itajahya, as well as it can be affirmed that the lignicolous habitat on the Geastrum genus in fact indicates parental relationships, and that it has arised only once at the evolutionary history of the genus

Corpo e Velhice: um estudo da qualidade de vida de idosos da Vila Vicentina Júlia Freire em João Pessoa

The aim of this study was to follow the daily routine of elderly individuals residing at the Vila Vicentina Júlia Freire (VVJF) nursing home in João Pessoa, Brazil, observing and analyzing as much as possible, the way in which they live in a group and how they deal, through personal experiences, with their own body image and with that of others. The results were obtained from information considered relevant, according to the perspectives of the residents themselves, contained in narratives of their history and related to their quality of life. Our interest lays in how they coped with changes in their bodies at old age and adapted to the challenges of this new phase. To obtain this information, with significant expressions, we used the Narrative Interview (NI) as a research tool in order to redeem their life experience and develop an understanding of their impressions about the life experience at the current nursing home. We selected, among the housed, ten subjects - actors - to appear as a sample of the group together. The design of our sample had a hybrid model, combining two types: random sample (probability) and an intentional sample (not probability). After recording transcripts and ensuring that all the subjects showed common interests that were relevant to the group, we chose three categories for analysis as follows: a. the elderly as seen by themselves and by others; b. religiosity as a moral factor; c. intimacy and relationships. Our choice was based on the importance of the theme as a multidisciplinary topic in the quality of life of populations. The subjects, chosen as spokespersons for the VVJF, spoke, among other things, about the way in which they viewed the world, their own body and how they experienced the environment and their fellow residents, in an attitude of reflection and criticism that confirms the lucidity of an old age conditioned to an elderly institution. The method allowed us to investigate our subjects from a multidisciplinary point of view. We suggest other studies in assorted areas of the human sciences, having as principle, man at the center of all our scientific questionings. The paradigm that the elder is, necessarily, unhappy in his sheltered has been, in this job, broken through the testimonies collected, establishing multiple perspectives of the analyzed subjects by their respective narrative records. Involving the participation of researchers with major in Administration, Communication and Law, this study filled, in this aspect, the requirements of the multidisciplinarity of the Program of Pos-Graduation in Health Science

Modelo matemático para predição do VO2máx em cicloergômetro baseado na análise dos gases expirados

Existem diversas equações para predição do VO2máx a partir de variáveis dentro do teste ergométrico em vários ergômetros, no entanto equação semelhante utilizando os limiares ventilatórios na ergoespirometria em teste sub-máximo no cicloergômetro não está disponível. O objetivo do presente estudo foi avaliar a precisão de modelos de predição do VO2máx com base em indicadores de esforço sub-máximo. Neste sentido foram testados em protocolo incremental máximo no cicloergômetro 7.877 voluntários, sendo 4640 indivíduos do sexo feminino e 3147 do sexo masculino, todos saudáveis não atletas, com idades acima de 20 anos, divididos randomicamente em dois grupos: A de estimação e B de validação. A partir das variáveis independentes massa corporal (MC) em kg, carga de trabalho no limiar 2 (WL2) e freqüência cardíaca no limiar 2 (FCL2) foi possível construir um modelo de regressão linear múltipla para predição do VO2máx. Os resultados demonstram que em indivíduos saudáveis não atletas de ambos os sexos é possível predizer o VO2máx com um erro mínimo (EPE = 1,00%) a partir de indicadores submáximos obtidos em teste incremental. O caráter multidisciplinar do trabalho pôde ser caracterizado pelo emprego de técnicas que envolveram pneumologia, educação física, fisiologia e estatística

Sanções disciplinares aplicáveis em caso de doping a atletas profissionais e não profissionais

A presente pesquisa descritiva do tipo documental centrou-se em analisar as sanções disciplinares aplicadas em caso de doping, a atletas profissionais e não profissionais que atuam no Brasil. A amostragem foi levantada através de um processo de seleção não probabilística intencional, utilizando-se como sujeitos, 18 atletas de uma modalidade esportiva dita não profissional: atletismo e 19 de uma modalidade profissional: futebol, de ambos os sexos, os quais tenham sido flagrados pelo exame de controle de dopagem da Confederação Brasileira de Atletismo (CBAt) e da Confederação Brasileira de Futebol (CBF). Como instrumentos de análise, foram utilizados os diagnósticos de dopagem positiva, arquivados junto a CBAt e CBF; além dos processos julgados pelo Superior Tribunal de Justiça Desportiva (STJD) do atletismo entre os anos de 2003/2007 e os processos julgados pelo STJD do futebol no ano de 2007. Os resultados demonstram que as sanções aplicadas aos desportistas diferem muito entre as modalidades incluídas no estudo. Enquanto encontramos, no atletismo a aplicação de sanções em conformidade com o Código Mundial Anti Doping (CMAD) com penalidades de no mínimo de dois anos, no futebol encontrou-se grande número de absolvições ou aplicação de penalidades conforme o Código Brasileiro de Justiça Desportiva (CBJD) que prevê penalidades muito inferiores. Por outro lado verificou-se ser a modalidade Futebol a que mais realiza controles, sendo certo que durante o ano de 2007 o desporto profissional realizou 4832 testes, ao passo que o desporto dito não profissional realizou tão somente 281. O caráter multidisciplinar do trabalho 12 pôde ser caracterizado pelo emprego de técnicas que envolveram direito, educação física, farmacologia

Discursos e práticas na formação de profissionais fisioterapeutas: a realidade dos cursos de fisioterapia na região nordeste do Brasil

This study had a multidisciplinary focus, investigating the areas of health and education, and proposes to discuss the formation of health professionals, requiring their understanding of the factors involved in the production of knowledge, given that this formation has an impact on the quality of human and social life. The aim of this work was to investigate the relationship existing between the process of physical therapist formation and the practical activities developed during the undergraduate course in the Northeast of Brazil. This is an exploratory descriptive study with qualitative significance. The sample consisted of 73 subjects (33 professors and 40 students) from 6 physical therapy courses at different institutions in the Northeast of Brazil. Data collection was conducted through focus group interviews. In addition, we used a school assessment instrument from the health area. The data, analyzed using dialectical hermeneutics, showed that the Northeast of Brazil has the second largest number of physical therapy courses in the country, with 93 (11 public and 82 private) out of a total of 510. These numbers represent a growth of 1062.5% since 1991. The pedagogical projects are guided by National Curricular Directives as well as by the country s health system. The prevalent pedagogy is that of transmission, and the contents/disciplines are generally not integrated with practice, a situation that hinders the integrality and interdisciplinarity of health care. It can be concluded that there is a need for implementing integrated curricula and for better qualified professors to effectively put this process into practice

Desenvolvimento de sistemas magnéticos com potencialidades terapêuticas para vetorização de fármacos

Magnetic targeting is being investigated as a means of local delivery of drugs, combining precision, minimal surgical intervention, and satisfactory concentration of the drug in the target region. In view of these advantages, it is a promising strategy for improving the pharmacological response. Magnetic particles are attracted by a magnetic field gradient, and drugs bound to them can be driven to their site of action by means of the selective application of magnetic field on the desired area. Helicobacter pylori is the commonest chronic bacterial infection. The treatment of choice has commonly been based upon a triple therapy combining two antibiotics and an anti-secretory agent. Furthermore, an extended-release profile is of utmost importance for these formulations. The aim of this work was to develop a magnetic system containing the antibiotic amoxicillin for oral magnetic drug targeting. First, magnetic particles were produced by coprecipitation of iron salts in alkaline medium. The second step was coating the particles and amoxicillin with Eudragit® S-100 by spray-drying technique. The system obtained demonstrated through the characterization studies carried out a possible oral drug delivery system, consisting in magnetite microparticles and amoxicillin, coated with a polymer acid resistant. This system can be used to deliver drugs to the stomach for treatment of infections in this organ. Another important finding in this work is that it opens new prospects to coat magnetic microparticles by the technique of spray-drying.

Atividade antibacteriana das plantas copaifera duckei dwyer e pseudobombax marginatum e sua interação com a superfície celular bacteriana

A resistência microbiana a antimicrobianos tem favorecido a busca por substâncias bioativas provenientes de plantas usadas na medicina popular, com o intuito de se obter novos fármacos com atividade antimicrobiana. Neste estudo, foi proposta a investigação da atividade antibacteriana do óleo-resina de Copaifera duckei e de diferentes extratos da casca de Pseudobombax marginatum, e seus possíveis mecanismos de ação. O potencial inibitório antibacteriano foi avaliado utilizando-se os métodos de difusão e diluição em ágar, e a bioautografia. O mecanismo de ação foi analisado por microscopia eletrônica, no qual se observou alterações na ultraestrutura bacteriana, e por eletroforese em SDS-PAGE, que determinou ação sobre as proteínas das superfícies celulares. A análise química foi realizada pelas técnicas de Espectrometria de massas acoplada ao Cromatógrafo a gás- EM/CG (C. duckei) e Cromatografia Líquida de Alta Eficiência- CLAE (P. marginatum). Entre as bactérias estudadas, B. cereus foi a mais suscetível às plantas em estudo, com concentrações inibitórias mínimas (CIMs) correspondentes a 0,3125 mg/mL para o óleo-resina de copaíba, e 0,5 mg/mL para extrato hidroalcoólico (1:1) e 0,512 mg/mL para a fração butanólica da casca P. marginatum, nos quais pôde-se observar alterações na parede celular do B. cereus, com remoção da camada S, espessamento da parede celular e formação de diversos septos nos centros de divisão celular. A análise química por EM/CG mostrou compostos terpênicos no óleo-resina de C. duckei, tendo como composto majoritário o β-bisaboleno, e a análise por CLAE mostrou a presença de compostos derivados da catequina na casca do P. marginatum. Desta forma, as plantas em estudo mostram um potencial antibacteriano considerável, podendo contribuir tanto na terapia antimicrobiana como na área de alimentos, tendo como um de seus prováveis sítios de ação a parede celular bacteriana

Testes bioquímicos para avaliação do vigor em sementes de Mimosa caesalpiniaefolia Benth

Mimosa caesalpiniaefolia Benth. is a forest species of the Mimosaceae family, recommended for recovery of degraded areas. The evaluation of vigor by biochemical tests have been an important tool in the control of seed quality programs, and the electrical conductivity and potassium leaching the most efficient in the verifying the physiological potential. The objective, therefore, to adjust the methodology of the electrical conductivity test for seeds of M. caesalpiniaefolia, for then compare the efficiency of this test with the potassium in the evaluation of seed vigor of different lots of seeds M. caesalpiniaefolia. To test the adequacy of the electrical conductivity were used different combinations of temperatures , 25 °C and 30 ºC, number of seeds , 25 and 50, periods of imbibition , 4 , 8 , 12 , 16 and 24 hours , and volumes deionized water, 50 mL and 75mL. For potassium leaching test, which was conducted from the results achieved by the methodology of the adequacy of the electrical conductivity test, to compare the efficiency of both tests , in the classification of seeds at different levels of vigor, and the period 4 hours also evaluated because the potassium leaching test can be more efficient in the shortest time . The best combination obtained in experiment of electrical conductivity is 25 seeds soaked in 50 mL deionized or distilled water for 8 hours at a temperature of 30 ° C. Data were subjected to analysis of variance, the means were compared with each other by F tests and Tukey at 5 % probability, and when necessary polynomial regression analysis was performed. The electrical conductivity test performed at period eight hour proved to be more efficient in the separation of seed lots M. caesalpiniaefolia at different levels of vigor compared to the potassium test

Caminho possível para o desenvolvimento do RN: a utopia do Polo Gás Sal

La présente étude sur la modernisation économique qui s est opérée dans le Rio Grande do Norte, constitue un débat concernant les tentatives de faire aboutir un projet de développement industriel fondé sur l exploitation des matières premières locales telles que le sel, le calcaire, les eaux mères et le pétrole, entre les années 70 et 90 du XXe siècle. Elle cherche à montrer, à partir de l observation de l action planifiée de l État national et régional, soutenu par le capital international et par les groupes économiques et politiques locaux, comment on a tenté d implanter, dans des conjonctures économiques distinctes, une industrie d intrants de base moyennant la création de deux pôles de développement : le Pólo Químico Industrial (1974) et le Pólo Gás Sal (1996). Elle est centrée sur l analyse des actions orientées vers la concrétisation de ces pôles, et prendra pour objet les politiques de développement émanant de l État national, en particulier celles qui relevaient du II PND et qui visaient, au cours des années 70, à l implantation d une industrie décentralisée dans la région Nordeste ; les règles fixées par le Plano Nacional de Desestatizações, destinées à promouvoir les privatisations des entreprises publiques brésiliennes, lesquelles ont rendu possible la vente d Alcanorte au groupe industriel commandé par Fragoso Pires, et les politiques définies par l État national et régional, rassemblées sous le titre de « guerre fiscale » afin d attirer des capitaux internationaux susceptibles de rendre viable le Pólo Gás Sal. Il y est démontré que l État a coordonné un ensemble d actions dans les domaines de l infrastructure et des exonérations fiscales et financières, dans le but d accélérer la transition d une économie primaire et exportatrice vers une économie moderne, industrialisée. Et que le concours simultané de forces économiques et sociales particulièrement expressives le capital national et international, les élites locales n a pas suffi pour promouvoir la modernisation industrielle escomptée des secteurs chimique et pétrochimique. Parmi les différentes raisons qui ont contribué à un tel échec, on peut mentionner : l absence d une accumulation interne préalable de capital ; la dépendance de l économie locale par rapport à la technologie et au capital des groupes économiques internationaux ; l inconsistance des stratégies de développement relevant de la politique qui caractérisait la « guerre fiscale », et la fragilité de la représentation politique locale

Poéticas de um saber brincar: a vez e a voz do fandango

The present thesis aims to get to know and to analyze the elements which make up the poetical performance of the Fandango from Canguaretama confirming/corroborating an eminently theatrical model. It still highlights the producers´ history, its asset production and its insertion in community where we had contact with two other types of performances: the daily and the ritualistic. Such actions both combine and present different meanings and objectives, promoting distinct readings and experiences. Looking at these three ways of performances poetic, daily, and ritual enabled to go deeper in cultural aspects of the studied community and, thus, check over what is going on in these events, how they accord with and conceive a popular performance context. The research could substantiate the existence of a theatrical model whose performance by means of the voice and active presence of playful bodies, implied in getting to know the consolidation of a cultural patrimony which reveals us the past, but, especially, the present, its people and its place

Trajetórias da adoção cadastral em Fortaleza: o Estado modelando as relações familiares

Esta disertación tiene como objetivo principal identificar las motivaciones de los adoptantes catastrales, pues la regularidad estadística en el universo adoptivo nacional apunta para una preferencia por las adopciones al modo brasileño o listas. La hipótesis principal señala que las caracterizaciones de los sujetos en foco, en cuanto a su pertenencia religiosa y al nivel de educación formal, ejercen fuerte influencia en su opción por la adopción catastral. Apoyándose en la teoría del habitus de Pierre Bourdieu, se pudo constatar que la cultura individual es lo que orienta los límites de la acción de los sujetos y, en el caso de los adoptantes catastrales, en sus diferentes habitus, se encuentra la explicación para sus trayectos y tentativas adoptivas. Es importante recordar que sus habitus son unificados por el Estado. En la colecta y análisis de los datos, se realizó un trabajo cualitativo y cuantitativo fundamentado en los siguientes recursos: observación directa, consultas de documentos oficiales, aplicación de formularios y entrevistas semiestructuradas. Las observaciones fueron realizadas en instituciones relacionadas al proceso de las adopciones catastrales, así como mediante encuestas sobre los adoptantes. Se analizaron, también, documentos referentes al regimiento de esas instituciones, especialmente en cuanto a las orientaciones relativas a la práctica adoptiva estudiada. Se observó una discrepancia entre el discurso oficial y lo que efectivamente las instituciones practican en su cotidiano. Por fin, en cuanto a las entrevistas realizadas con los adoptantes, fue verificado que ellos tienen un nivel socioeconómico y formación escolar superior a la media de la población de la ciudad de Fortaleza, así como participan de alguna comunidad religiosa y son miembros de familias que representan el modelo socialmente dominante nuclear burgués

Max Stirner, o único e o que lhe é próprio: uma interpretação e(m) algun(s) ensaio(s)

This work has a study object the main thinking work of Johan Kaspar Schmidt well known as Max Stirner (1806-1856) - originally titled (in German), Der Einzige und sein Eigentun, and translated into Portuguese by the Portuguese publisher Antígona in 2004, under the title The Unique and its Ownership. This book was known in 1844 although its publication dated 1845 seen that the censor of that time rejected the publication request in that year - saying that ( ) in concrete passages of that work, not only God, Christ, the church and the religion are usually object of proposal blasphemy, but also because all social order, the state and the government are defined as something that should not exist simultaneously as one justifies the lie, perjury, the murder and suicide and denies the ownership right. After this first attack and rejection by its bearing the unique come to be others target, due practically to all the philosophical political thinkers its time including thinkers like Ludwig Feuerbach and Karl Marx & Friedrich Engels in spite of, on the other hand, having inspired formulations and reformulations of many of those thinkers that were against then in their times, as well as those thinkers that came after then such as Nietzsche himself. Even though this work was be victim of powerful attempts of erasing it of history, it has shown a great repercussion power and that is the main reason that led us to ask the following questions what is its big originality? , how could his author arrive at a so impactant perspective? What is its most legitimate political place? We endeavored in elaborate answers to those questions trough the exegesis of its text, taking in account both the scholarship environment where the author produced his intellectual life set - and the detailed reading of texts linked to discussion in focus, where this reading is always based upon the meaning and senses traced by the texts and its contexts as a precaution against the limits and the traps of the readings which shed light markedly on strict letter of the phrases constructs. Ours conclusions point at to the idea that a work like this , that subverts the characteristic ways of thought of the modernity, completely, continues being a utter odds, without rank in the history of thought and the moderns political practices, finding parallel possibility only, in a very special way, with a certain autharchic perspective of Ancient Greece

A trajetória dos movimentos socioambientais em Sergipe : personagens, instituições e estratégias de comunicação

The research aimed to study the emergence, role, and the possibilities of environmental movements in Sergipe, running through an analysis of the period between 1983 and 2011. This goal has been guided by the core issue of research, which was to analyze the relationship between the mission, structure and action of environmental organizations in Sergipe. The research arose from the need to map and critically evaluate the environmental movement in Sergipe. The methodological procedures focused on the literature search, survey papers in Sergipe a time gap of 28 years, detailed analysis of nine "movements" and selected in-depth interviews, semi-structured interviews with dozens of social actors involved in the area. In conclusion, we observed that environmentalism in Sergipe, from its inception, was associated with recovery of consciousness regarding the environment, to combat local problems of degradation, and the search for legitimacy of public opinion. Although the environmental movement have been, at times, the attention of mass media, the movement failed to leave the niche and achieve a more representative portion of society. You can still see the deep relationship between the profile of environmental leaders, capital strength and the practical results of the environmental actions and finally, it was observed that the action of the movements has much stronger bond with the relationship of the organization and its main leaders with the other "environmentalist," than with the structure and mission of the institution
