To assist in upland rice breeding programs, estimated genetic and phenotypic parameters are extremely important in the selection of superior lines. Thus, the objective of this study was estimate the genetic and phenotypic parameters of upland rice lines of the breeding program of UFLA in partnership with Embrapa Arroz e Feijao and Epamig. The experiment was installed in an experimental area of the Department of Agriculture at UFLA. It was evaluated 36 upland rice lines of the preliminary trial of the 2014/15 season, in randomized blocks, with three replications and plots consisted of five rows and each row has four meters. For this, it was evaluated the characters: plant height (cm), yield (kg·ha-1), 100-grain weight, days until flowering, percentage of filled grains and rice blast severity. The variance analysis and genetic parameters were estimated using the software SAS. To evaluate the experimental precision was estimated the accuracy, which varied between 63% and 98%, showing experimental precision, moderate to high. The lines differed significantly for all characters, meaning there is genetic variability among genotypes evaluated. With intensity of selection of 10% of lines, it was obtained a genetic gain of 325.29 kg·ha-1 in the character productivity, a plant height (cm) reduction in 5.50 cm, and days until flowering, with a reduction of 9.23 days, with selection of earlier plants. The estimated values for heritability ranged from 38% - 96%. Estimates confirm the possible success with the selection of the upland rice lines for these characters.

<i>Sitophilus</i>Weevil Reaction in Upland Rice Elite Lines

American Journal of Plant Sciences 2015年第12期6卷 1916-1919页

Insects of the genus Sitophilus are among the most destructive pests in rice storage, and the best strategy to control it is to use resistant genotypes. In this study, 26 upland rice elite lines were evaluated for Sitophilus weevil reaction on grain weight. The seeds were placed in plastic recipients stored in a room with temperature and lightning simulating a warehouse environment. The number of living weevils and the grain weight were obtained in two evaluations, one 35 days after storage, and the other 35 days after infestation. The lines differed statistically for number of living weevils and for grain weight in both evaluations. The correlations between these two characters were -?0.99 and -?0.47 for the first and the second evaluation (P < 0.05), respectively. The lines BRS Pepita, AB 112089 and AB 112090 were the most susceptible. Seventeen of the twenty-six elite lines were resistant in both evaluations and could be successfully used in upland rice breeding programs.

Objective: The objectives were to characterize the scientific production on Health-Related Quality of Life of pregnant women, identify the areas that are most affected during pregnancy and puerperal period and identify the instruments used to assess quality of life related to health in pregnant women. Methods: For the integrative review, 11 articles published from 2006 to 2013 in the PUBMED, MEDLINE, CINAHL, SCOPUS and SCIELO were selected. Result: Data showed scarce publication from nursing professionals, prevalence of non-experimental studies conducted mainly in Brazil. The most commonly instruments used were the WHOQOL-BREF and SF-12. The presence of pain, nausea and vomiting, depression, low education, younger age and absence of partner negatively affect the quality of life of pregnant women. Practicing physical activity and being socially supported during pregnancy favour a better quality of life. In the domain of social relations, sexuality was the only affected facet. Conclusion: Gaps in the level of evidence considered weak were identified. We suggest bigger role of nurses in research on the subject so that there will be the development of effective interventions to support nursing practice and ensure quality care and consequently improve the quality of life of women in pregnancy and childbirth.

Maternal Predictors for Quality of Life during the Postpartum in Brazilian Mothers

Health 2015年第3期7卷 371-380页

Introduction: The postpartum period can have a significant physical, emotional, and social impact on the quality of a woman’s life. Most postpartum research has focused on physical complications and only a few studies have specifically investigated quality of life. The purpose of this study was to explore predictors affecting the quality of life of postpartum Brazilian mothers. Study Design and Methods: A cross-sectional Quality of Life survey was performed in 210 Brazilian mothers during the early postpartum period. Data were collected using an interview technique and two instruments: 1) a maternal questionnaire and the 2) Maternal Postpartum Quality of Life tool/Brazilian version. The association between maternal characteristics and quality of life in the post-partum period was investigated with bivariate and multivariable analyses. Results: Mothers who had the best Quality of Life were white, registered students, 30 - 40 years of age, who were married or living with a partner, and without physical complaints;in addition, they had at least an 8th grade education, more than 4 children, and had attended more than 8 prenatal visits with a nurse. The stepwise model indicated that white race (p < 0.05) and married or living with a partner (p < 0.05) were the best predictors of Quality of Life in postpartum women. Conclusions and Clinical Implications: Marital status and race conditions may predict quality of life in postpartum Brazilian mothers. In addition, improved knowledge concerning the postpartum, maternal experience may help develop health interventions to enhance the quality of life of this population.

Open Journal of Nursing 2014年第9期4卷 630-636页

Exploratory study was conducted in the Crato Public Prison, State of Ceará, Brazil, aiming to understand the knowledge and experiences related to the preventive aspects of Sexually Transmitted Diseases (STDs) in the prison context. The target population of the study consisted of 14 female inmates, 10 of whom agreed to participate. Data collection occurred in June 2012 through recorded semi-structured individual interviews. We investigated quantitative, socio-demographic and sexual variables. In qualitative data analysis, we applied the Meaning Interpretation Method. The female vulnerability was aggravated by the early onset of sexual activity, lack of knowledge about STDs, non-adoption of preventive measures and history of prostitution. The following categories emerged from the qualitative assessment: Knowledge about STD/AIDS versus Personal Experience;Use of contraception as STD/AIDS prevention within the Public Jail;Habits of inmates: alcohol and tobacco;and Characterization of the conjugal visit area.
