To clarify the optimal management of these patients, we evaluated the early impact of isolated CABG on moderate ischemic MR. METHODS AND RESULTS(More)
BACKGROUND Flow cytometry is a rapid and reliable method for measuring nuclear DNA content and genome size. Fluorochrome binding characteristics, sample preparation and differences in DNA condensation, and availability of binding sites can cause variations in results obtained. METHODS Blood samples from 82 vertebrate species were collected in 10% dimethyl(More)

OBJECTIVE The purpose of this study was to determine whether abdominoplasty performed in conjunction with adjunct procedures would(More)
The etiology of congenital diaphragmatic hernia (CDH) is unknown. Phenotypic patterns of CDH defects provide clues about normal diaphragm development and the pathophysiology of CDH. We report a case of a patient who was diagnosed with CDH postnatally and was found on imaging to have simultaneous Bochdalek and Morgagni hernias on the right side. During the(More)
