We confirmed that commercial three- or four-component Spodoptera frugiperda (J.E. Smith) pheromone lures had a high nontarget capture rate for Leucania phragmatidicola Guenée, which compromised monitoring efforts in the northeastern United States. We compiled taxonomic features to distinguish L. phragmatidicola from S. frugiperda, and we compared five new(More)
OBJECTIVE To evaluate sternal healing, complications, and costs after sternotomy closure with rigid plate fixation or wire cerclage. METHODS This prospective, single-blinded, multicenter trial randomized 236 patients at 12 US centers at the time of sternal closure to either rigid plate fixation (n = 116) or wire cerclage (n = 120). The primary endpoint,(More)

AIM To determine optimal exposure parameters when performing digital skull radiographs in infants with suspected non-accidental injury (NAI). METHOD Anteroposterior and lateral post-mortem skull radiographs of six consecutive infants with suspected NAI were made at six exposure levels for each projection. Entrance surface doses ranged from 75-351 microGy.(More)
many champions. Originally, in pre-evolutionary Europe, biogeography was unified by the common aim of uncovering the centre of origin, a concept derived from biblical texts. Organisms either were created in the places they were found or they moved there from elsewhere (Buffon, 1766; Sclater, 1858). Whether or not the organisms evolved was not an issue in(More)
