RATIONALE Acetylcholine esterase (AchE) inhibitors are known to remediate symptoms of Alzheimer's disease. However, only few systematic data exist on the effects of cholinergic treatment on cognitive functions in normal subjects. OBJECTIVE This study evaluated the effects of donepezil, an inhibitor of AchE, on cognitive performance in young and healthy(More)
Platelet-derived growth factor (PDGF) induces the expression of human stromelysin-1, a matrix metalloproteinase involved in tumor invasion and metastasis. Here it is shown that stromelysin-1 gene induction by PDGF depends on Ras and involves three previously identified promoter elements (the stromelysin-1 PDGF-responsive element (SPRE) site, the two(More)
Low oxygen conditions (2%) during post-compaction culture of bovine blastocysts improve embryo quality, which is associated with a small yet significant increase in the expression of glucose transporter 1 (GLUT-1), suggesting a role of oxygen in embryo development mediated through oxygen-sensitive gene expression. However, bovine embryos to at least the(More)
