Saúde & Transforma??o Social , 2010,
Abstract: The aim of this study was to identify the planning potentialities and limits in the Family Health Strategy in order to make the actions of Oral Health possible in an Amazonian municipal district. For this a qualitative study was carried out with data treated using the dialectic hermeneutic perspective, deriving from the analysis of the interviews with the Municipal Secretary of Health, the Coordinator of Oral Health and the dentists who composed the Oral Health Teams and from the documentary analysis of the City Health Council acts (2002 the 2008), the Municipal Health Plans (2002 the 2008) and the Management Reports (2003 the 2007). The results demonstrated that the main limiting factors were: the deficiencies in the training of managers and dentists in the work relationships of the multidisciplinary team and in the planning and reorganization of the demand. This demonstrates that the municipal district presents difficulty in accomplishing the proposals of Primary Care in Oral Health.
Dental caries and gingivitis among 15 to 19 year-old students in Manaus, AM, Brazil
Rebelo, Maria Augusta Bessa;Lopes, Márcia Cristina;Vieira, Janete Maria Rebelo;Parente, Rosana Cristina Pereira;
Brazilian Oral Research , 2009, DOI: 10.1590/S1806-83242009000300005
Abstract: in the light of the scarcity of epidemiological studies on the oral health of the general population within the context of the amazon region, this study aimed to estimate the prevalence of dental caries and gingivitis, as well as to evaluate the need for restorative treatment, among school students aged 15 to 19 years in the city of manaus, am, brazil. a cross-sectional study was carried out on a sample of 889 students from within city limits who were enrolled in 26 public and private schools. dental examinations were performed to obtain the dmft index (decayed, missing and filled teeth) as well as to determine the treatments needed. the gingival index (l?e & silness) was used to classify gingivitis. the intra-examiner diagnostic concordance was 94% and the kappa statistic was 0.91. the dmft index found was 4.65 (± 0.12), without significant difference between the sexes or skin color groups. the prevalence of dental caries was 87.4%. restoration of a dental surface was the greatest need (59.3%). slight gingival inflammation was present in 78.5% and gingival bleeding following probing occurred in 53.3%. although the dmft index was lower than that observed for the northern region of brazil, restorative dental services are lacking for this population. additional studies are suggested to better understand the differences found.

Abstract: Avaliaram-se a produtividade de matéria seca (MS), propor o de laminas e composi o bromatológica de Brachiaria spp., colhidas com 42 dias de rebrota o, em Diamantina, MG. Para a determina o dos teores de MS, PB, FDN, FDA e lignina utilizaram-se o esquema em parcelas subsubdivididas, no DIC, com quatro repeti es. Nas parcelas foram distribuídas as cultivares Basilisk, Marandu, Xaraés, Llanero e B. humidicola comum; nas subparcelas, dois cortes, e, nas subsubparcelas, dois anos experimentais. A produ o de MS total e a propor o de laminas foram analisadas em esquema de parcelas subdivididas, com espécies/cultivares nas parcelas e anos nas subparcelas. A produ o de MS no segundo ano (3 cortes) foi mais alta que no primeiro (2 cortes), destacando-se as cultivares Basilisk, Xaraés e Llanero. De modo geral, as cultivares apresentaram teores satisfatórios de PB, mais altos no segundo ano. Os teores de FDN foram mais baixos no segundo ano e os de lignina mais baixos no primeiro ano. As cultivares Xaraés e Marandu destacam-se pela elevada propor o de folhas e apresentam composi o bromatológica semelhante a da cultivar Basilisk. Associando-se a composi o bromatológica com a produtividade de MS, recomendam-se as cultivares Xaraés e Basilisk para as condi es do Alto Vale do Jequitinhonha. Dry matter production, proportion of leaf blades and chemical composition of Brachiaria spp. harvested at intervals of 42 days of regrowth, in Diamantina, MG were evaluated. The DM, CP, NDF, ADF and lignin contents were analyzed in a split-split plot completely randomized design, with four replicates. Five cultivars of Brachiaria were distributed in the plots, two cuts in the split-plot, and two experimental years in the split-split plot. The dry matter production and the proportion of leaf blades were analyzed in a split plot completely randomized design, with cultivars in the plots and years in the subplots. The dry matter production in the second year (3 cuts) was higher than in the first (2 cuts), especially with the cultivars Basilisk, Xaraés and Llanero. Generally, the cultivars presented satisfactory levels of CP, with higher values in the second year. The contents of NDF were lower in the second year and the lowest levels of lignin were in the first year. Cultivars Xaraés and Marandu stand out for the high proportion of leaves and presented chemical composition similar to the Basilisk cultivar. Based on the chemical composition and dry matter production, Xaraés and Basilisk cultivars are recommended for cultivation in the Jequitinhonha High Valley.

Abstract: the family health strategy (fhs) is based on teamwork and demands changes in the work process of the health care units, breaking the traditional model centralized on the physician's role. the present study aims to propose a theoretical model to assess power relations within the multidisciplinary team, grounded on hannah arendt's work. based on an analysis of legal documents of the fhs and on arendt's assumptions, a theoretical model for fhs evaluation was set up using a qualitative and hermeneutic-dialectic approach. in order to test the model, focus groups with health care teams and individual interviews were conducted in the municipality of manacapuru - state of amazonas (northern brazil). the results show that each professional performs his/her role in isolation, without sharing with others. the local management policy limits the collective work and does not use leadership principles; it is characterized as tyranny in arendt's perspective, which brings discredit to the fhs.

Abstract: the rice (oryza sativa) breeding program of the rice and bean research center of the brazilian agricultural company empresa brasileira de pesquisa agropecuária (embrapa) is well established and provides new cultivars every year to attend the demand for improved high yielding varieties with tolerance to biotic and abiotic stresses. however, the elite genitors used to compose new populations for selection are closely related, contributing to the yield plateau reached in the last 20 years. to overcome this limit, it is necessary to broaden the genetic basis of the cultivars using diverse germplasm such as wild relatives or traditional varieties, with the latter being more practical because they are more easily crossed with elite germplasm to accelerate the recovery of modern plant types in the breeding lines. the objective of our study was to characterize the allelic diversity of 192 traditional varieties of brazilian rice using 12 simple sequence repeat (ssr or microsatellite) markers. the germplasm was divided into 39 groups by common name similarity. a total of 176 alleles were detected, 30 of which (from 23 accessions) were exclusive. the number of alleles per marker ranged from 6 to 22, with an average of 14.6 alleles per locus. we identified 16 accessions as a mixture of pure lines or heterozygous plants. dendrogram analysis identified six clusters of identical accessions with different common names and just one cluster with identical accessions with the same common name, indicating that ssr markers are fundamental to determining the genetic relationship between landraces. a subset of 24 landraces, representatives of the 13 similarity groups plus the 11 accessions not grouped, was the most variable set of genotypes analyzed. these accessions can be used as genitors to increase the genetic variability available to rice breeding programs.

Revista Brasileira de Zootecnia , 2003,
Abstract: Objetivou-se verificar as doen as foliares que ocorrem na alfafa em Lavras-MG, no período de setembro de 1997 a outubro de 1998. Um ensaio foi conduzido em blocos ao acaso em esquema de parcelas subdivididas. Nas parcelas foram alocadas foram 35 cultivares e nas subparcelas 11 épocas de avalia o. Avalia es foram realizadas aos 28 dias após corte, quando foram coletadas dez hastes de alfafa por parcela para avalia o da desfolha e determina o da severidade das doen as. Os dados foram submetidos à análise de variancia e os contrastes entre médias comparados pelo teste de Scott-Knott a 5%. A mancha-de-Leptosphaerulina ocorreu durante o ano todo, porém com maior severidade nos períodos mais frios do ano. A mancha-negra-das-folhas-e-caule apresentou maior severidade no final do ver o e início do outono e a ferrugem revelou maior severidade apenas nas avalia es de novembro. As maiores porcentagens de desfolha foram obtidas nos meses mais frios do ano. As cultivares mais resistentes à mancha-de-Leptosphaerulina, cercosporiose e à desfolha foram a Crioula, P30 e Costera SP INTA. As cultivares MH 15 e MH 4 destacaram-se pela maior resistência à ferrugem.
