Resistance to bacterial soft rot caused by Erwinia carotovora subsp. carotovora is a quantitative trait. The narrow-sense heritability was from 42% to 60% in the studied populations. Griffing's diallel analysis and generation mean analysis indicated that additive genetic effects were most significant, and the resistant sources involved in this study(More)
Erwinia soft rot is a destructive disease of Brassica rapa vegetables. Reliable sources of resistance and control methods are limited, so development of highly resistant breeding lines is desirable. Protoplasts from B. rapa and B. oleracea genotypes selected for resistance to soft rot were fused in order to combine different sources of resistance. Twelve(More)
BACKGROUND Treatment regimens that require fewer dosage units and less frequent dosing to decrease the complexity and cost of care are among the strategies recommended to improve compliance with antihypertensive therapy. Simplifying therapy may be particularly important for elderly patients, who are more likely to have co-morbid conditions and to be taking(More)
Mist-chamber, field, and detached leaf inoculation procedures identified plants resistant to bacterial soft rot [Erwinia carotovora subsp. carotovora, (Ecc)] in Brassica rapa and related species. The mist-chamber seedling inoculation provided the best correlation of mean disease severity ratings with the field plant inoculation (r = 0.67**) and was used to(More)
For Brassica crop breeders, weedy crucifers are potential sources of disease resistance and other useful traits. However, few species have been evaluated or are well represented in germplasm collections. In this study, we evaluated 24 Eurasian crucifer species for disease reaction to North American isolates of the crop pathogens A. brassicicola and X.(More)
OBJECTIVES The purpose of this study is to evaluate (a) health-related quality of life (HRQL) after vertical banded gastroplasty (VBG) (Mason) and (b) predictors of HRQL. SUBJECTS Eighty-two consecutive patients were assessed preoperatively and then after 6, 12 and 24 months. Patients filled out questionnaires for subjective appraisal of HRQL (physical(More)
Extract: The development of a new drug requires a major investment of capital, human resources, and technological expertise. It also requires strict adherence to regulations on testing and manufacturing standards before a new drug can be used in the general population. All these requirements contribute to the cost increases for a new chemical entities (NCE,(More)
PURPOSE Neutropenic complications (NCs) after myelosuppressive chemotherapy are associated with significant morbidity and mortality. We described NC rates by using US hospital discharge data. MATERIALS AND METHODS This cross-sectional analysis used data from the US National Inpatient Sample database. Hospital discharges with cancer diagnoses(More)
The effect of rowing ergometer design upon power delivery and coordination patterns of the rowing stroke was analyzed for 14 elite rowers. Rowers were tested in three ergometer conditions: the fixed stretcher Concept2c ergometer, the Concept2c ergometer mounted on sliding rails, and the sliding stretcher RowPerfect ergometer. Ergometers were instrumented to(More)
