Casearia sylvestris na permeabilidade gástrica à sacarose em equinos submetidos a protocolo de indução de úlcera gástrica

Estudos em animais de laboratório sugerem um efeito antiulcerogênico do extrato de Casearia sylvestris. Esse extrato ainda não foi estudado para a profilaxia e/ou o tratamento de úlceras gástricas em equinos. Para avaliar a influência do extrato de C. sylvestris na permeabilidade gástrica à sacarose, seis equinos adultos foram submetidos a modelo de indução de úlceras gástricas. Os animais foram submetidos ao teste de permeabilidade à sacarose antes e ao término do protocolo de restrição alimentar intermitente, para detecção de ulceração gástrica. Durante os sete dias da indução, os animais foram submetidos a tratamentos diários via sondagem nasogástrica com extrato de C. sylvestris (9mg kg-1 de peso corpóreo) ou veículo (ágar). Após intervalo de 32 dias em piquete, para permitir a cicatrização das úlceras induzidas, cada animal foi submetido novamente ao protocolo de indução de úlcera gástrica, e os tratamentos foram alternados. Dessa forma, cada animal foi submetido a ambos os tratamentos em períodos distintos. A concentração de sacarose na urina foi determinada para cada amostra obtida, por cromatografia líquida de alto desempenho e detecção amperométrica pulsátil. Não foram observadas alterações nos exames clínicos e hemogramas. O tratamento com o extrato de C. sylvestris evitou o aumento da concentração de sacarose urinária (P<0,05) quando comparado ao veículo, sugerindo um efeito antiulcerogênico gástrico em equinos. Estudos mais amplos incluindo gastroscopia são necessários para avaliar a possibilidade de usar o extrato para a profilaxia e/ou o tratamento das úlceras gástricas em equinos.

Universo encantado do cuidado na autopoiese docente: uma viagem epistemológica transdisciplinar

The health transition experienced in Brazilian health care model requires a metamorphosis in human and society, placing new demands on health and education. The Faculty of Science, Culture and Extension of Rio Grande do Norte (Facex), aware of their responsibilities to the Health System, which brings the principle of comprehensiveness as its structural axis, dared to implement a course of nursing in complex thinking and Experiential Pedagogy Humanescente with curriculum inter / transdisciplinary. For deployment of proprosta was not enough to reform thinking of educators, there was a need corporalizar new teaching practices that are aimed at the integral formation of human beings. In this context, emerged the workshop on Human Education autopoietic, self-forming area of the educator, where he developed an Action Research Existential (PA-E) which enabled experience, describe and analyze how the human autopoietic educators could contribute to the practice educational humanescente transdisciplinary curriculum project. Were worked out in meetings, knowledge necessary to practice the transdisciplinary 1st Meeting - learn to create; 2nd Meeting - learn to recognize the laws of nature with emphasis on complexity theory, 3rd Meeting - learn to organize, 4th meeting - namely autoestruturar themselves; 5th Meeting - know how to choose, 6th Meeting - knowing innovate 7th Meeting - namely exchange. Next an autobiographical perspective, we chose the metaphorical possibility to narrate the ways and strategies covered by the author and apprentice in the company of the Little Prince de Saint-Exupery, in search of a sensible pedagogical practice complex, which promotes re-enchant transdisicplinar education. The route involved five methodological connections: a literature review which relate to training for care in undergraduate nursing: the study of learning processes that drive the formation humanopoiética, emphasizing the relationship that involves the complexity and embodiment in the educational process transdisciplinary, highlighting the analysis of what is to learn from the findings of biosciences and recent cognitive theories of Maturana and Varela, the description of the interdisciplinary curriculum of the nursing course of Facex and Training Workshop, Human autopoietic, with emphasis on Experiential Education Humanescente; the report of seven meetings of the Workshops (cocoon), recording the experiences and listening to educators (luminescent butterflies), the final reflections with learning opportunized. Experientiality lived through, the expressions and words, educators say the influence of workshops for their teaching practices, highlighting it as a space for selforganizing, creating, learning and enchantment, and can identify the workshop as a place of transformation necessary for deployment an interdisciplinary curriculum. The knowledge emerging from the study indicate the need for permanent spaces of self, in which the educator learns from its body, between cognitive processes and vital, and in the experiences of their formative process the opportunity to act on the dimensions of knowing and being

PROEJA FIC/Fundamental no IFRN-Campus Mossoró: das intenções declaradas ao funcionamento de um curso em espaço prisional

This research aims to analyze the FIC Course of Assistant Technician in Service Management and Quality, integrated to elementary education / EJA form developed by IFRN MO Campus between 2011 and 2013 in the form of a PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL. We seek to understand the adhesion between the national guidelines postulated for the Program, established in PPC and mediations with the process conceived in the run of the course. Guiding by the socio-critical approach and the dialogical paradigm, the theoretical-epistemological mark is especially buoyed by the theoretical contributions of Ciavatta (2005) , Rock (2011) , Haddad and Di Pierro (2000), Freire (2005), Marx (1982), Ramos (2005), Frigotto; Ciavatta; Ramos (2005), Moura (2012), and also on education in prisons by Onofre (2007, 2011), Bueno (2007), Julião (2011) and Foucault (2001). We assume that an action that enables professional qualification as FIC courses articulated to the EJA in the context of education in prisons have conceptual, methodological, political and pedagogical implications for it focuses challenges, weaknesses and opportunities on the same area of education., We have developed four techniques of data collection based on procedures and tools of qualitative research, such as document analysis, a student survey, the conduction of focus groups with teachers and administrators of the course and on-site observation. Mediated by the investigated context, results showed that the consolidation of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL goes beyond the intentions officially declared. It is inferred that after seven years of its creation, even though it keeps some potential, this program is not being satisfactorily developed and it shows weaknesses national and locally, it is set at low capillarity, it has a limited scope, and dissolved essential public commitments to the course development. The effectiveness of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL as part of an emancipatory inclusion social policy, according to official statement, entails approximating the legal logic with social logic, so as not only to propagate discourses and enforce worship to specific and successful experiences that reach only a minority, but to provide actual and necessary conditions to promote the breadth and social quality of the offered deals in this program format

Conhecimento dos adolescentes sobre métodos contraceptivos: pesquisa-ação em uma unidade do programa saúde da família de Natal

It is a descriptive study with a qualitative approach, and an action-research type, which aimed to analyze the changes of knowledge about contraceptive methods invested to a teenager group attended in Igapó Family Healthcare Unit, in the city of Natal/RN, after consent and institutional assent of Ethics Committee of Rio Grande do Norte Federal University (Protocol No. 131/07). It were researched 16 teenagers of both sexes, with age ranging from 11 to 16 years. We used two structured questionnaires, one in the initial diagnosis and another during the seven meetings of the focus group, in addition to the field notes and the meetings discussions transcriptions. The data-collection was performed in the period of two months by a team composed by a nurse the research coordinator, a dentist, a nursing assistant, a community-based healthcare worker and a nursing academic. The quantitative and qualitative data were organized, tagged and categorized into spreadsheet in Microsoft Excel, being held a thematic analysis of speeches performed by the study participants. The results were presented as tables, graphics, photos, drawings and word clippings. The educational strategy developed in focus group allowed adolescents to discuss, exchange ideas and opinions on several contraceptive methods, providing expansion in knowledge of all contraceptives discussed, especially those natural and surgical, which were less mentioned at the beginning of the study. Among the advantages of the contraceptive methods listed by teenagers, was highlighted avoiding pregnancy and STDs in use of the barrier method of condom. As for the disadvantages more frequently noted by the survey with the misuse of barrier methods, was highlighted get pregnant, acquire STD's and do not prevent STD's in hormonal, natural and surgical methods. Adolescents showed consistency between the advantages and disadvantages and types of contraceptive methods, showing a widening in knowledge among them. It may be said that, in general, those surveyed had a good understanding about the use of the various contraceptive methods. Thus, the study participants had positively evaluated all the criteria used to qualify the meetings in the focus group. The action strategy of the focus group should be encouraged by professionals who work with teenagers, since they prefer to live in groups, one characteristic of adolescence.

Repercussões da terapia comunitária no processo de trabalho na estratégia saúde da família: um estudo representacional

The Community Therapy (CT) is in a practice of therapeutic effect and may also be considered as a technology takes care of the therapeutic procedure group, whose purpose is to promote health, prevent illness, developed within primary care in mental health. In this study we sought to understand the social representations of health professionals who work with the Community Therapy, on use of the Family Health Strategy (FHS) in the city of Joao Pessoa. This is a field research with a qualitative view Moscovician Theory of Social Representations, held with seven professionals of the FHS, therapists of Community Health District II. The empirical data were obtained by carrying out two thematic therapies in April 2009, which were wheeled CT. It was used as a technique for analyzing the collective subject discourse, and the data presented through graphs, charts, maps, pictures and graphics and arranged in three stages: Subjects of the study, characterizing the study participants; Social Representations of Therapist Community presenting and discussing the social representations of therapists community studied on CT, and Consequences of Community Therapy at the Family Health Strategy, discussing the meanings attributed by the study participants about changes in FHS. Meanings were attributed to the CT by the therapists studied originated from the speeches, songs, drawings and constructed, and that presented by schematic illustration show the relation between the representations: life, listening, faith / light, change, transformation. The web, symbol of CT, appeared on the images constructed by the representatives of the study and represents the formation of bonds that allows the construction of social support networks that strengthen relationships among community. In the study, proved by professionals who have the meanings about the changes in the work process from the introduction of CT, and shown that the change took place within a more welcoming attitude on the part of professionals, the relationship between Team members had no significant changes, explained by the low compliance of team members to the CT in relation to the user front, the bond was strengthened, and this involved strengthening the role of the therapist community. It is recognized, thereby transforming the character of CT in building links with users, requiring, however, that the team is viewed as offering therapeutic services, not the professional therapist. Therefore, the CT for being a new phenomenon in health services and community belonging, it fits like a novelty which affects the construction of a representation dispute. Still, can contribute to the reorganization of mental health care in line with the new model of mental health care advocated by the Psychiatric Reform.

Caracterização molecular e diversidade genética de diferentes variedades de abacate por marcadores microssatélites

Pertencente à família Lauraceae, o abacateiro compreende três raças hortícolas: antilhana, guatemalense e mexicana. Os marcadores moleculares são uma ferramenta rápida e eficaz para estudos genômicos, uma vez que detectam o polimorfismo diretamente ao nível do DNA e não sofrem qualquer tipo de influência ambiental. Com base nesse polimorfismo, é possível fazer inferências sobre as relações entre o genótipo e o fenótipo dos indivíduos, o que, em última análise, permite aumentar a eficiência dos programas de melhoramento. Diante o exposto, o objetivo foi investigar a diversidade genética entre sete variedades de abacate a partir de 5 lócus de marcadores moleculares microssatélites (SSR). Nas amostras de abacateiros avaliadas, encontrou-se um total de 18 alelos, com uma média de 3,6 alelos por lócus. O dendrograma gerado a partir de análise de agrupamento UPGMA agrupou, separadamente do resto dos genótipos, a cultivar Geada da raça Antilhana, possivelmente por esta variedade ser uma raça pura, e o restante foi agrupado em dois grandes grupos das raças, a Guatemalense e a Mexicana. Os genótipos das sete variedades de abacate apresentam diversidade genética nos cinco lócus de marcadores moleculares microssatélites (SSR) avaliados, o que indica que são materiais promissores para utilização em futuros programas de melhoramento.

Estudo do potencial do pacu (Piaractus mesopotamicus) como agente de controle biológico de Egeria densa, E. najas e Ceratophyllum demersum

Visando fornecer subsídios para elaboração de sistema de manejo integrado das grandes massas de plantas daninhas aquáticas submersas em lagos e represas, o presente trabalho teve como objetivo verificar a eficiência do pacu (Piaractus mesopotamicus) como agente de controle biológico de Egeria densa, E. najas e Ceratophyllum demersum. As espécies de plantas daninhas foram oferecidas individualmente, duas a duas e as três espécies juntas. Verificou-se que este peixe tem uma eficiência média de controle dessas plantas daninhas variando entre 28 e 100%, podendo eliminar uma massa verde dessas plantas, com a mesma quantidade de seu peso, em sete dias. A eficiência de controle diária aumentou com o tempo de predação. O pacu é mais seletivo para E. densa ou E. najas quando na presença de C. demersum. Não ocorreu alteração na eficiência de controle do pacu sobre E. densa ou E. najas em todos os tratamentos e nos três períodos estudados (três, cinco e sete dias).

Efeito de épocas de colheita e período de repouso pós-colheita sobre as características físicas de frutos e sementes de mamoneira

This study aimed to assess the effect of harvesting times and of post-harvest resting period on physical characteristics of fruits and seeds of castor bean (AL Guarany 2002 genotype) and to verify if theses characteristics could be used to identify the ideal harvest time. Nine times of raceme harvest were assessed from 30 to the 142 days after anthesis (DAA) at fourteen days intervals, and four conditions of resting; (without and with seven days of resting period of seeds extracted (bare), from fruits and fixed to the racemes). It was evaluated water content, seed thickness, and length, width, and weight of fresh fruits and seeds, and seedling emergence in sand. The statistical design was completely randomized with four replications. The harvest times and the post-harvest rest period affected the physical characteristics of fruits and seeds of castor bean but none of these have proved to be effective in the identification of the ideal harvest time.

Úlceras de pressão: um estudo com pacientes de unidade de terapia intensiva

To characterize patients according to gender, age category, internment time, diagnostical hypothesis and location of the pressure ulcer; to identify the susceptibility conditions, intrinsical and extrinsical factors present on ICU patients and to verify on the existence of association between the susceptibility conditions and the intrinsecal and extrinsecal factors on the occurrence of PU. Methods: It is a descriptive study, of longitudinal design of the panel type, with quantitative approach, performed on two ICU s of a private hospital located in Natal/RN, with 40 patients interned at these units. The data collection was performed on all three shifts through a structured observation and physical exam of the patients' skin form seeking to identify the presence of PU. Results: The greatest occurence of PU was on individuals of the male gender (70%) when compared to the female gender (30%), that difference being statistically significant (p=0,0267), with the male gender presenting 4,3 times greater chance of developing PU than the female; the predominant age category was from 60 years of age on (85%), 60,0% presented 1 to 2 PU s after 7 (seven) days of permanence in the ICU s, the predominant diagnostical hypothesis on the patients with PU were the respiratory diseases (42,3%) and the most frequent locations of PU were the sacral region (40,0%) and heels (36,0%). 25 PU s of stage I were diagnosed on 50,0% of the followed patients, with general incidence of 50,0% on both ICUs. from the 88 variables researched, 75 were identified on the patients from the study, being the predominant conditions (anemia, hypotension, leukocytosis, other diseases hypertension blood pressure, cardiac insuffience, pneumonia - and ansiolythic), the intrinsecal factors (diminished muscular strenght and/or mass, discrete edema, totally compromised mobile coordination and total inability for movement on the bed) and the extrinsecal factors (inadequate mattress type, permanence on a single position for >2 hours, shearing/friction force, bed clothes with folds that leave marks on the body, pressure force) predominated on patients with PU. The male gender variables (p=0,0267,OR=4,3), sedation (p=0,0006,OR=4,1), psychomotive agitation (p=0,0375,OR=5,8) and leukocytosis (p=0,0285,OR=5,0) presented a significant statistical diference when analyzed independently. We verified an association of 17,3%, statistically significant (p=0,0384), between the susceptibility conditions (anemia, leukocytosis and hypotension), the intrinsecal factors (age equal or above 60 years, diminished/absent pain sensibility and smooth, fine or delicate skin) and the extrinsecal factors (inadequate mattress, pressure forces, shearing/friction force, permanence on a single position for more than 2 hours, elevation between 30 to 45 degrees and inadequate bed clothes' conditions), with a chance ratio of 4,6 times the risk of occurrence of PU on the patients that presented the referred association. Conclusion: The incidence of PU detected on the ICU-interned patients was high and we made evident the existence of association between the susceptibility conditions, the intrinsecal and extrinsecal factors on the occurrence of PU s on the ICUinterned patients, and thus we accept the alternative hypothesis proposed on the study

The feedlot performance of 30 post-weaning 3/4 Canchim 1/4 Nellore calves, with seven months of age and 208,8 kg of liveweight, was evaluated. Three different protein sources in isocaloric and isonitrogenous diets with 60:40 forage: concentrate ratio were used. The diets, fed ad libitum, constituted of corn silage, corn grain, mineral mix and a different protein source for each treatment: cottonseed meal, soybean meal and whole soybean. The weight gain, feed: gain ratio, dry matter and crude protein intake were evaluated for the growing (84 days) and fattening phases (84 days) and for the overall period. An economic study of young bulls production model was realized at the end of experimental period. Soybean meal based diet presented the best animal performance and provided R$ 51.30/head of net profit - the best economic result.
