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.(More)
Ferdinand Sauerbruch (1875–1951) was a pioneer of thoracic and cardiac surgery and is undoubtedly one of the twentieth century's most outstanding surgeons. Before 1904 operations on the thorax met with fatal complications due to pneumothorax. Sauerbruch developed a pressure-differential chamber that maintained normal respiration and enabled safe operations(More)
Plasminogen activator inhibitor-1 (PAI-1) and two-chain high molecular weight kininogen (HKa) exert anti-adhesive properties in vitronectin-dependent cell adhesion. Here, the hypothesis was tested that these anti-adhesive components promote apoptosis in vascular cells. PAI-1 or HKa induced a 2- to 3-fold increase in apoptosis of human umbilical-vein(More)
Despite being the most widely used and vital therapy in neonatology, optimal strategies for the use of oxygen in preterm infants remain controversial. Achieving the balance between attaining adequate tissue oxygenation and avoiding oxygen toxicity is challenging. There remains a paucity of clear evidence based guidance for clinicians on safe oxygen(More)
Endomyocardial fibrosis is an uncommon cause of congestive cardiac failure characterized by severe diffuse thickening of the endocardium, and the overall long-term prognosis of this disease is generally considered poor. We report a case of endomyocardial fibrosis that was initially treated by endocardial resection and mitral valve replacement, which was(More)
BACKGROUND AND AIM OF THE STUDY Although iatrogenic ischemic complications due to occlusion of the circumflex coronary artery following mitral ring annuloplasty are rare, they may be fatal if not recognized and treated promptly. The study aim was to assess the implantation safety of a novel biodegradable intra-annular mitral valvuloplasty ring in ex-vivo(More)
We report a patient who presented with pericardial tamponade 9 months after percutaneous closure of a patent foramen ovale using a BioSTAR septal closure device (NMT Medical, Boston, MA). During the operation, bleeding was observed on the posterior aortic root caused by a nonendothelialized strut. The device was explanted, followed by pericardial patch(More)
Non-Hodgkin lymphoblastic lymphomas are very uncommon tumors that rarely involve the heart; however, when they do, they typically cause cardiac symptoms. Herein, we describe the case of a young woman who presented with respiratory symptoms. These were caused by a high-grade lymphoblastic lymphoma, which originated in the left inferior pulmonary vein and(More)
