Abstract: most strawberry (fragaria × ananassa duchesne) cultivars used in brazil are developed in other countries, it became clear the need to start the strawberry breeding program in the country. to start a breeding program is necessary the genetic characterization of the germplasm available. molecular markers are important tools that can be used for this purpose. the objectives of the present study were to assess the genetic similarity among 11 strawberry cultivars using rapd and issr molecular markers and to indicate the possible promising crosses. the dna of the eleven strawberry cultivars was extracted and amplified by pcr with rapd and issr primers. the dna fragments were separated in agarose gel for the rapd markers and in polyacrylamide gel for the issr markers. the genetic similarity matrix was estimated by the jaccard coefficient. based on this matrix, the cultivars were grouped using the upgma method. the dendogram generated by the rapd markers distributed the cultivars in three groups while the issr markers generated two groups. there was no direct relationship between the marker groups when the two types of markers were compared. the grouping proposed by the issr markers was more coherent with the origin and the genealogy of the cultivars than that proposed by the rapd markers, and it can be considered the most efficient method for the study of genetic divergence in strawberry. the most promising crosses, based on the genetic divergence estimated from the rapd and issr molecular data were between the tudla and ventana and the oso grande and ventana cultivars, respectively.

Abstract: the objective of this work was to evaluate the degree of genetic similarity among beggar-ticks accesses, susceptible and resistant to acetolactate sintase (als) herbicide inhibitors and the relationship among the genetic similarity and geographic distance of this accesses. beggar-ticks seeds were sampled at paraná state and were grown in the greenhouse at universidade federal do rio grande do sul, porto alegre, rs, brazil, in october 2004. after the confirmation of resistance or susceptibility to als inhibitors herbicides, the dna extraction was performed. through rapd analysis, it was possible to evaluate the genetic similarity among beggar-ticks accesses. in the whole analysis of the accesses, from 20 primers assessed, only 17 displayed polymorphism and amplified a total of 94 bands. average genetic similarity was low (37%). regression analysis evidenced that there is no relationship between genetic and geographic distance for the beggar-ticks accesses. low general similarity among accesses evidences that resistance in the region is represented by selection of resistant individuals already existing in the population.

Abstract: the objective of this work was to determine the transcript profile of tomato plants (lycopersicon esculentum mill.), during fusarium oxysporum f. sp. lycopersici infection and after foliar application of salicylic acid. the suppression subtractive hybridization (ssh) technique was used to generate a cdna library enriched for transcripts differentially expressed. a total of 307 clones was identified in two subtractive libraries, which allowed the isolation of several defense-related genes that play roles in different mechanisms of plant resistance to phytopathogens. genes with unknown roles were also isolated from the two libraries, which indicates the possibility of identifying new genes not yet reported in studies of stress/defense response. the ssh technique is effective for identification of resistance genes activated by salicylic acid and f. oxysporum f. sp. lycopersici infection. not only the application of this technique enables a cost effective isolation of differentially expressed sequences, but also it allows the identification of novel sequences in tomato from a relative small number of sequences.

Abstract: Unconventional vegetables, in general, are plants that have been largely consumed by the population at some point and, because of changes in eating behavior, now present reduced economic and social expression and have lost ground to other vegetables. The objectives of this study were to perform phytochemical screening of the ethanol extracts of Rumex acetosa L., Tropaeolum majus L., Solanum muricatum, Stachys byzantina K. Koch and Solanum betaceum Cav. and evaluate their antioxidant potentials via the methods involving scavaging of the DPPH free radical and the ABTS radical, phosphomolybdenum and reducing power. In phytochemical screening, five species of unconventional vegetables tested positive for tannins; for sesquiterpene, lactones and other lactones. These tests were positive for Tropaeolum majus L. and Rumex acetosa L., Solanum betaceum Cav. and Solanum muricatum tested negative for steroids. Only Solanum betaceum Cav. gave positive tests for flavonoids. Among the five plant species studied, Stachys byzantina K. Koch presented the greatest antioxidant potential in all the methods evaluated.

Abstract: objective: the aim of this study was to evaluate the applicability of the rachs-1 (risk adjustment in congenital heart surgery) as a predictor of surgical mortality in a pediatric population of a public hospital of the northeast of brazil. methods: from june 2001 through june 2004, 145 patients undergone surgical treatment of chd in our institution of whom 62% were female, and the mean age was 5.1 years. the rachs-1 was used to classify the surgical procedures into categories of risk 1 to 6, and logistic regression analysis was used to identify the risk factors related to surgical death. results: age, type of chd, pulmonary flow, surgical procedure, pump time and cross clamp time were identified as a risk factor for postoperative mortality (p<0.001). there was a linear correlation between the categories of the rachs-1 and the mortality rate; however, the observed mortality was greater than the predicted figures by that scoring system. conclusion: although the rachs-1 is easily applicable, it can not be applicable in our scenario because it takes into account only the surgical procedure as a categorized variable, not considering others factors presented in our scenario that could interfere in the final surgical result.

Abstract: A dinamica de funcionamento da Biblioteca Municipal “Prof. Ernesto Manoel Zink” relaciona-se com uma problemática maior: investigar se esse espa o público tem representado, para os moradores de Campinas, uma possibilidade de inser o no mundo da escrita, um ambiente de letramento, tendo em vista um projeto político de investimento em leitura. Evidenciaram-se inúmeras dificuldades enfrentadas pelos bibliotecários e assistentes de biblioteca entrevistados, sendo que duas limita es têm uma importancia fundamental para se entender um problema que diz respeito n o só à Biblioteca Central de Campinas, mas às bibliotecas públicas de um modo geral: o número reduzido de leitores, que n o apenas estudantes, e a falta de clareza quanto à fun o social da biblioteca, por parte dos funcionários que, em sua maioria, n o percebem o alcance social e cultural de sua prática, deixando de se preocupar com a forma o de leitores e com a amplia o das condi es de letramento daqueles que já participam do universo da leitura. Os dados também apontam para a necessidade de que a Secretaria Municipal de Educa o, à qual as bibliotecas públicas est o subordinadas, realize projetos no sentido de democratizar a leitura na cidade. The functioning dynamics of the Professor Ernesto Manoel Zink City Library is related to a major problem: investigating whether such public space has been representing not only a possibility of inclusion in the world of writing, but also an environment of literacy for the inhabitants of Campinas – having in mind a political project of investment in reading. Several difficulties have been pointed out by librarians and library assistants, and two limitations are fundamental to the understanding of a problem which concerns not only the Central Library of Campinas, but also all public libraries in Brazil: a reduced number of readers, since most users are students, and the staff’s lack of clarity concerning the social function of libraries. Due to the fact that librarians and assistants are not able to realize both the social and cultural reach of their jobs, they do not care about the formation of readers and the enlargement of the conditions of literacy of those who already take part in the universe of reading. Furthermore, the data show that it is essential that the City Department of Education, to which the public libraries in Campinas are subordinate, create projects in order to democratize the reading in the city.
