Aspectos biológicos de Cycloneda sanguínea (Coleóptera: Coccinellidae) alimentadas con pulgones criados en algodón transgénico Bollgard I

Cycloneda sanguinea is an important biological control agent of aphid cotton. The objective of this study was to evaluate the biological aspects of C. sanguinea fed with nymphs and adults of Aphis gossypii reared in DeltaOPAL and NuOPAL cultivars (Bollgard I). The experiment was conducted in the laboratory under controlled temperature (25 +/- 1 degrees C), humidity (70 +/- 10%) and photophase (12 hours). The experimental design was completely randomized, and treatments aphids fed on the two cultivars, and replicates 40 individuals. Each larva was individually until adult emergence of the predator in Petri dishes of 9 cm in diameter with moistened filter paper. For evaluation of individual adults were five couples newly emerged in plastic pots 12 cm in diameter and 9 cm tall, with filter paper for oviposition. The parameters evaluated were: duration and viability of the larval stage, pupal stage duration and survival, adult longevity, reproductive period, post-reproductive and total number of eggs per female. The duration of the larval stage of C. sanguinea was lower when fed aphids reared on the cultivar NuOPAL, while adult longevity and the reproductive period were higher. The female fertility and egg viability were also lower.

Índices fisiológicos associados com a performance aeróbia em corredores de endurance: efeitos da duração da prova

O objetivo deste estudo foi analisar a validade do consumo máximo de oxigênio (VO2max), da velocidade correspondente ao VO2max (vVO2max), do tempo de exaustão na vVO2max (Tlim), da economia de corrida (EC) e do limiar anaeróbio (LAn) para a predição da performance de atletas de endurance. Quatorze corredores de endurance (33,4 ± 4,4 anos; 62,7 ± 4,3kg; 166,1 ± 5,0cm; VO2max = 60,4 ± 5,9ml.kg-1.min-1) realizaram os seguintes testes: a) competição simulada nas distâncias de 1.500 e 5.000m. e; b) testes de laboratório para a determinação do VO2max, vVO2max, EC, LAn e Tlim na intensidades de 100% vVO2max. As velocidades (km/h) da vVO2max (18,7 ± 0,8), LAn (17,3 ± 1,1) v1.500m (19,9 ± 0,8) e v5.000m (17,9 ± 0,9) foram significantemente diferentes. A regressão múltipla stepwise revelou que o LAn foi o único preditor da performance da v5.000m, explicando 50% da variação desta performance. Para a v1.500m, o Tlim e a vVO2max explicaram 88% da variação da performance. Com base em nossos resultados, pode-se concluir que a validade dos índices fisiológicos (VO2max, vVO2max, Tlim, EC e LAn), para a predição da performance aeróbia de atletas de endurance, é dependente da distância da prova (1.500 x 5.000m) analisada.

Evaluation of the Capillary Blood Glucose Self-monitoringProgram

OBJECTIVE: to evaluate the structure, process and results of the Capillary Blood Glucose Self-monitoring Program in a Brazilian city. METHOD: epidemiological, cross-sectional study. The methodological framework of Donabedian was used to construct indicators of structure, process and outcome. A random sample (n = 288) of users enrolled and 96 health professionals who worked in the program was studied. Two questionnaires were used that were constructed for this study, one for professionals and one for users, both containing data for the evaluation of structure, process and outcome. Anthropometric measures and laboratory results were collected by consulting the patients' health records. The analysis involved descriptive statistics. RESULTS: most of the professionals were not qualified to work in the program and were not knowledgeable about the set of criteria for patient registration. None of the patients received complete and correct orientations about the program and the percentage with skills to perform conducts autonomously was 10%. As regards the result indicators, 86.4% of the patients and 81.3% of the professionals evaluated the program positively. CONCLUSION: the evaluation indicators designed revealed that one of the main objectives of the program, self-care skills, has not been achieved.
