... that the original work is properly attributed. Summary: We analyze common and distinct developmental and cardiovascular toxicities caused by cigarette smoke and snuff, and include a new zebrafish embryo model for studying abdominal aortic aneurysm. Zebrafish Aneurysm Aorta Tobacco Snuff...

... of endurance training on the gene expression and protein content and/or activity of elastin, elastase, cathepsin K, and plasmin in skeletal and heart muscles and in the aorta. Healthy rats were randomly divided into untrained ( n =10) and trained ( n =10; 6 weeks of endurance training with increasing load...

... hematopoietic development is as yet unknown. We show here that hematopoietic stem cells (HSCs) differentially express α IIb β 3 and α v β 3 integrins throughout development. Whereas the first HSCs generated in the aorta at mid-gestation express both integrins, HSCs from the placenta only express α v β 3...
