Caracterização de cultivares de pessegueiro e de nectarineira por marcadores moleculares

Em espécies de estreita base genética, como o pessegueiro e a nectarineira (Prunus persica (L.) Batsch), a utilização de marcadores moleculares para a caracterização de cultivares é de grande importância, além do potencial de uso para fins de proteção. As técnicas de eletroforese em gel e RAPD foram empregadas com o objetivo de caracterizar as cultivares de pessegueiro Granada, Esmeralda, Jade, Eldorado, Riograndense, Capdeboscq, Aldrighi, Precocinho, Diamante, Turmalina, Maciel, BR-1, Pepita, Coral, Chinoca, Marfim, Chiripá, Della Nona e Planalto, e as de nectarineira Dulce e Anita. Foram analisadas isoenzimas de 6-fosfogluconato desidrogenase e fosfatase ácida em pólen, peroxidase, fosfoglucoisomerase, aspartato transaminase e isocitrato desidrogenase em folhas, e malato desidrogenase, leucina aminopeptidase e fosfoglucomutase em pólen e folhas. Dos 50 primers testados, 11 foram escolhidos para análise de RAPD em folhas. As análises de similaridade e de agrupamento entre os genótipos foram feitas empregando-se o coeficiente de Jaccard e o método da média aritmética não ponderada. Apesar das diferenças detectadas nas isoenzimas de malato desidrogenase em pólen e folhas de pessegueiro e nectarineira, o baixo polimorfismo apresentado pelos demais sistemas não permitiu a caracterização de todas as cultivares por essa técnica. Os marcadores RAPD, associados ou não à eletroforese de isoenzimas, foram eficientes para caracterizar as cultivares de pessegueiro e nectarineira.

Diversidade genética em cultivares locais e comerciais de feijão baseada em marcadores RAPD

O objetivo deste trabalho foi caracterizar a diversidade genética dentro e entre cultivares locais e comerciais de feijão, por meio de marcadores RAPD, e avaliar a capacidade destes em agrupar genótipos de feijão de acordo com o centro de domesticação e coloração de semente. Foram avaliadas 35 cultivares, 13 comerciais e 22 locais, de diversas regiões do Rio Grande do Sul. As distâncias genéticas foram obtidas pelo complemento do coeficiente de similaridade de Sorensen-Dice e a representação simplificada destas distâncias realizada mediante um dendrograma. Marcadores RAPD foram eficientes ao agrupar cultivares de acordo com o centro de domesticação, mas não foram capazes de separar as cultivares de acordo com a coloração da semente. Cultivares locais e comerciais, mesoamericanas, foram agrupadas separadamente. Cultivares comerciais, em cultivo no Rio Grande do Sul apresentam alto grau de similaridade.

Psychological distress in adult survivors of childhood cancer: the Swiss Childhood Cancer Survivor study.

PURPOSE: To evaluate the degree of psychological distress in adult childhood cancer survivors in Switzerland and to characterize survivors with significant distress. METHODS: Childhood cancer survivors who were age younger than 16 years when diagnosed between 1976 and 2003, had survived more than 5 years, and were currently age 20 years or older received a postal questionnaire. Psychological distress was assessed using the Brief Symptom Inventory (BSI). Raw scores were transformed into T scores according to the German norm sample, and the proportion of participants being at increased risk for psychological distress was calculated (case rule: T > or = 63). t tests and univariable and multivariable logistic regressions were used for statistical analyses. RESULTS: One thousand seventy-six survivors (63.% of eligible survivors, 71.9% of contacted survivors) returned the questionnaire, 987 with complete data on BSI. Comparison with the norm populations showed lower T scores (T < 50) in the Global Severity Index (GSI; T = 46.2), somatization (T = 47.6), obsessive-compulsive tendencies (T = 46.9), and anxiety (T = 48.4). However, more childhood cancer survivors (especially women) had increased distress for GSI (14.4%), interpersonal sensitivity (16.5%), depression (13.4%), aggression (16.9%), and psychotic tendencies (15.6%) than the expected 10% from the norm population. Caseness was associated with female sex, being a single child, older age at study, and self-reported late effects, especially psychological problems. CONCLUSION: Results show that childhood cancer survivors, on average, have less psychological distress than a norm population but that the proportion of survivors at risk for high psychological distress is disproportionally large. Monitoring psychological distress in childhood cancer survivors may be desirable during routine follow-up, and psychological support should be offered as needed.

La ejecución hipotecaria en tiempos de crisis

L’objectiu del present treball es l’estudi del procediment d’execució hipotecaria. Arrel de la quantitat de desnonaments produït com a conseqüència de la crisi econòmica en que España es troba immersa, a la repercussió mediàtica d’aquests, a la pressió social i a alguns pronunciaments jurisprudencials a favor de la figura de la dació en pagament, s’ha fet necessària una modificació legislativa d’aquest procediment, regulat a la LEC. Aquest treball tractarà sobre la hipoteca en termes generals, el procediment d’execució hipotecaria que existia fa poc més d’un any i totes les modificacions que s’han dut a terme en l’actualitat amb el propòsit de millorar la situació dels deutors hipotecaris. Finalment, es tractarà sobre la figura de la dació en pagament, les seves característiques i alguns pronunciaments sobre aquesta figura.

Characterization of potato genotypes using molecular markers

The objective of this work was to characterize 27 potato genotypes, using molecular markers. Polyacrylamide gel electrophoresis, RAPD techniques and isozymes of esterase, phosphoglucomutase and soluble proteins were analyzed in tubers, and isocitrate dehydrogenase, aspartate transaminase, phosphoglucomutase and peroxidase, in leaves. Eighteen primers were tested and four were chosen, kits OPX (01, 04 and 09) and OPY (07), to analyze RAPD markers in leaf extracts. Similarity and cluster analysis were conducted using Jaccard coefficient and the unweighted pair-group method using arithmetic average. Despite the differences detected in the analysis of proteins and isozymes in the tubers, as well as of isozymes in the leaves, the characterization of all genotypes through gel electrophoresis was not possible, while RAPD markers were efficient to characterize all the 27 genotypes.

Evolució dels nitrats analitzats a l'aigua de 87 fonts situades en 28 municipis de la comarca d'Osona

La comarca d’Osona ha disposat sempre d’aigua abundant i de bona qualitat, però en els darrers anys s’ha observat un increment del contingut de nitrats a les aigües subterrànies. Des de 1988 i fins a l’actualitat es mostreja puntualment l’aigua d’algunes fonts i se n’analitzen els nitrats. En aquest estudi s’analitza l’evolució del contingut de nitrats i com ha afectat a la mineralització de l’aigua d’aquestes fonts i en quin estat es troben actualment. La legislació actual (RD 140/2003) considera que valors de nitrats a l’aigua de consum superiors a 50 mg/l poden provocar problemes de salut pública.

Influence of label information on dark chocolate acceptability

The aim of the present work was to study how the information on product labels influences consumer expectations and their acceptance and purchase intention of dark chocolate. Six samples of dark choco- late, varying in brand (premium and store brand) and in type of product (regular dark chocolate, single cocoa origin dark chocolate and high percentage of cocoa dark chocolate), were evaluated by 109 con- sumers who scored their liking and purchase intention under three conditions: blind (only tasting the products), expected (observing product label information) and informed (tasting the products together with provision of the label information). In the expected condition, consumer liking was mainly affected by the brand. In the blind condition, differences in liking were due to the type of product; the samples with a high percentage of cocoa were those less preferred by consumers. Under the informed condition, liking of dark chocolates varied depending on both brand and type of product. Premium brand chocolates generated high consumer expectations of chocolate acceptability, which were fulfilled by the sensory characteristics of the products. Store brand chocolates created lower expectations, but when they were tasted they were as acceptable as premium chocolates. Claims of a high percentage of cocoa and single cocoa origin on labels did not generate higher expectations than regular dark chocolates.
