Análise de polimorfismo de locos microssátelites em feijoeiro comum.

Nesse estudo foi avaliada a geração F5:6 do cruzamento Pérola x Bat477, cultivares contrastantes para a características de tolerância a seca. Foi avaliado, quanto ao polimorfismo, um conjunto superior a 500 marcadores, porém o polimorfismo existente entre os parentais é pequeno e gira em torno de 10%

Behavioral phenotype of children and adolescents with Prader-Willi syndrome

OBJETIVO: Identificar, em um grupo de crianças e adolescentes com síndrome de Prader-Willi, as principais características do fenótipo comportamental. MÉTODOS: A amostra foi composta por 11 crianças e adolescentes com diagnóstico clínico e citogenético-molecular da síndrome de Prader-Willi. A técnica de coleta de dados foi o Inventário dos Comportamentos de Crianças e Adolescentes entre 6 e 18 anos (CBCL/6-18). A análise de correlação bivariada, com nível de significância p<0,05, foi usada para testar a associação entre as variáveis analisadas. RESULTADOS: Os principais resultados mostraram um perfil comportamental considerado como clínico em várias das escalas do CBCL/6-18. Observou-se um padrão comportamental com alta frequência de respostas de agressão, quebra de regras e oposição. Identificaram-se correlações estatisticamente significativas entre problemas de atenção e sociais e problemas de pensamento e comportamento de quebrar as regras. CONCLUSÕES: Os pacientes investigados representam um grupo com risco psiquiátrico e alterações de comportamento que, em longo prazo, poderão evoluir para transtornos de 2009humor, do déficit de atenção e hiperatividade e transtorno desafiador e de oposição, dentre outrosOBJECTIVE: To identify the main characteristics of the behavioral phenotype of children and adolescents with Prader-Willi syndrome. METHODS: Eleven children and adolescents with clinical and cytogenetic-molecular diagnosis of Prader-Willi syndrome were studied. Data collection was obtained by the Child Behavior Checklist for Ages 6-18 (CBCL/6-18). Bivariate correlations were used to test the association between the analyzed variables, being significant p<0.05. RESULTS: The behavioral profile obtained was considered as clinical in different scales of the CBCL/6-18 tool. A behavioral pattern with high frequency of aggression, rule breaking and opposition was observed. Statistically significant correlations between attention and social problems and between thought problems and breaking rules were identified. CONCLUSIONS: The studied patients represent a group of psychiatric risk, with behavioral changes that, in the long-term, can lead to mood disorders, attention deficit hyperactivity disorder and oppositional defiant behavior, among other disordersInstituto Presbiteriano Mackenzie - MackPesquis

Pseudo-dynamic method for structural analysis of automobile seats

This work describes the application of a pseudo-dynamic (PsD) method to the dynamic analysis of passenger seats for the automotive industry. The project of such components involves a structural test considering the action of dynamic forces arising from a crash scenario. The laboratory certification of these automotive components consists essentially on the inspection of the propagation and extension of plastic deformations zones in metallic members of the seat structure as consequence of the mutual action between the seat and the passenger fastened to the seat via seat belt anchorages. This work presents a relatively simple experiment using PsD techniques as a novel method to performa test equivalent to the dynamic model of a dummy-seat pair subjected to impulsive loads from a car crash. Essentially, the PsD test method is a hybrid and hierarchic computer-driven testing procedure where a numerical algorithm and experimental step are used and combined on-line in order to solve a problem in the scope of structural dynamics. The implementation of the method is not expensive and has the leading advantage of offering the operator a total control of any intermediate structure state during the test still keeping the realism of a real dynamic testing.Project: NDT-AUTO Ref 13-02-2003-FDR-01281 (Agencia de Inovação

Isolation of micropropagated strawberry endophytic bacteria and assessment of their potential for plant growth promotion.

Twenty endophytic bacteria were isolated from the meristematic tissues of three varieties of strawberry cultivated in vitro, and further identified, by FAME profile, into the genera Bacillus and Sphingopyxis. The strains were also characterized according to indole acetic acid production, phosphate solubilization and potential for plant growth promotion. Results showed that 15 strains produced high levels of IAA and all 20 showed potential for solubilizing inorganic phosphate. Plant growth promotion evaluated under greenhouse conditions revealed the ability of the strains to enhance the root number, length and dry weight and also the leaf number, petiole length and dry weight of the aerial portion. Seven Bacillus spp. strains promoted root development and one strain of Sphingopyxis sp. promoted the development of plant shoots. The plant growth promotion showed to be correlated to IAA production and phosphate solubilization. The data also suggested that bacterial effects could potentially be harnessed to promote plant growth during seedling acclimatization in strawberr
