Increased expression of disintegrin-metalloproteinases ADAM-15 and ADAM-9 following upregulation of integrins alpha5beta1 and alphavbeta3 in atherosclerosis.

Regulation of alphavbeta3 and alpha5beta1 integrin function plays a crucial role in atherosclerosis. Possible regulators of integrin-matrix interactions are integrin-binding ADAMs (proteins with a disintegrin- and metalloproteinase-domain), like ADAM-15 and ADAM-9. Molecular interactions between ADAM-15, alpha5beta1, and alphavbeta3 have been demonstrated.

[Penetrating knife injury of the heart. Emergency management and definitive treatment: case report and review of the literature].

The outcome of patients with penetrating heart injuries depends to a great extent on aggressive primary care and fast transport to the closest appropriate trauma center. There, after confirming the diagnosis, the injured victim has to be transferred without any delay to the operating room where the penetrating injury can be dealt with. The importance of resolute emergency management is shown based on a case presentation and a review of the current literature.

Endothelin-1 and vasopressin plasma levels are not associated with the insertion/deletion polymorphism of the human angiotensin I-converting enzyme gene in patients with coronary artery disease.

The objective was to investigate whether the renin-angiotensin (RA) system and related peptides endothelin-1 (ET-1) and vasopressin (VP) influence the development of coronary artery disease (CAD). Angiotensin I-converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism has been associated with the risk of CAD. The ACE I/D polymorphism determines ACE activity, but plasma levels of other RA system components remain unchanged.

Insulin and local growth factor PDGF induce intimal hyperplasia in bypass graft culture models of saphenous vein and internal mammary artery.

Objective: In arteriosclerosis and bypass graft stenosis, intimal proliferation is controlled by local and systemic growth factors, such as platelet derived growth factor (PDGF) or insulin. Intimal hyperplasia can be produced in organ culture models. Our aim was to compare neointima formation in two organ culture models of internal mammary artery (IMA) and saphenous vein (SV), with special reference to the influence of systemic and local growth stimuli.
