PURPOSE Expression of ErbB-1 and ErbB-2 (epidermal growth factor receptor and HER2/neu) in breast cancer may cause tamoxifen resistance, but not all studies concur. Additionally, the relationship between ErbB-1 and ErbB-2 expression and response to selective aromatase inhibitors is unknown. A neoadjuvant study for primary breast cancer that randomized(More)
BACKGROUND A randomized, double-blind, multicenter study was conducted to compare the anti-tumor activity of letrozole vs. tamoxifen in postmenopausal women with ER and/or PgR positive primary untreated breast cancer. PATIENTS AND METHODS Three hundred thirty-seven postmenopausal women with ER and/or PgR positive primary untreated breast cancer were(More)
We report on the 13C NMR visibility of the C-1 glycosidic carbon of alpha-particulate glycogen in perfused rat liver. We used rats fed ad libitum, animals refed after a 48 h fast with a sucrose supplement with or without glucocorticoid treatment, and gsd/gsd rats with a hepatic glycogen storage disease due to phosphorylase kinase deficiency. Thus we studied(More)
We used computer simulations to see whether small sample size (SSS) int roduced a systemat ic e r r o r in est imating the ROC curve, which shows how well two overlapping populations (d isease-pos i t i ve , D+, and disease-negat ive, D-) can be separated. The overlapping populations are customari ly drawn with a smooth, continuous, Gaussian curve as i f(More)
Health promotion concept and practices have brought many significant changes even in disease management and care settings. In the Ottawa charter, health promotion is defined as "the process of enabling people to increase control over, and to improve, their health". However, care settings are in contradiction with this process on several levels (focus on(More)
We perfused livers from fed rats with a balanced salt solution containing 1 mmol/L glucose. Under these conditions a low steady rate of glycogenolysis was observed (approximately 1.7 micromol glucose equivalents/g/min; 20% of the maximal glycogenolytic activity). Nitric oxide (NO) transiently stimulated hepatic glucose production. A maximal response (on(More)
