Sequence data from the chloroplast-encoded gene rbcL were obtained for 24 liverworts, a basal group of embryophytes. Maximum likelihood and parsimony analyses of these data, along with data from other major green plant lineages, confirm hypotheses based on morphological data, such as the paraphyly of bryophytes, and the basal position of liverworts.(More)
To identify factors that influence students to choose primary care or non-primary care specialties, the authors surveyed the 509 graduating students at the Medical College of Georgia School of Medicine in 1988, 1989, and 1990. Using a Likert-type scale, the 404 responding students rated potential influences on their specialty choices from 1, very negative,(More)
We examined the relation of fatty acid composition of plasma phospholipids and cholesterol esters with carotid artery intima-media thickness (a measure of atherosclerosis) in 2872 white men and women aged 45-64 y from the Minneapolis center of the Atherosclerosis Risk in Communities Study. In both men and women, average carotid intima-media thickness was(More)
The combined effect of clofibrate and a fat-modified diet was determined in 17 hyperlipidemic patients: 7 type IIA, 7 type IV, 2 type VI(IIB), and 1 type III. Control serum lipid levels and lipoprotein patterns and their alteration with a fat-modified diet had been determined previously 1/2 to 2 years for 3 patients, and 6 to 10 years for 14 patients.
