OBJECTIVE
The tyrosine kinase receptor Axl is expressed in the vasculature and Gas6 is the ligand. The extracellular part of Axl (sAxl) can be found in circulation. The aim of this study was to determine plasma concentrations of Gas6 and sAxl in patients with abdominal aortic aneurysms (AAA) and to
BACKGROUND
Bicuspid aortic valves predispose to ascending aortic aneurysms, but the mechanisms underlying this aortopathy remain incompletely characterized. We sought to identify epigenetic pathways predisposing to aneurysm formation in bicuspid patients.
METHODS
Ascending aortic aneurysm tissue
Hyperglycaemia following branched endovascular repair (BEVAR) of extensive aortic aneurysms is associated with post-operative lower extremity weakness (LEW). Insulin administration to maintain euglycaemia appears to decrease LEW rates. The purpose of this study was to examine changes TH01 is a tetrameric short tandem repeat locus located in intron 01 of the tyrosine hydroxylase gene. The tyrosine hydroxylase catalyzes the hydroxylation of L-tyrosine to L-DOPA and is the rate limiting enzyme in the synthesis of catecholamines like noradrenaline or adrenaline, which are pivotal in
Abdominal aortic aneurysm (AAA) is characterized by vascular remodeling with increased infiltration of inflammatory cells and apoptosis/modulation of vascular smooth muscle cells (SMCs). Imatinib is a selective inhibitor of several tyrosine kinases, including PDGF receptors, Abl, and c-kit. The
Marfan syndrome (MFS) is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix fibrillin-containing microfibrils and dysfunction of TGF-β signaling. Here we identify the molecular targets of redox stress in aortic aneurysms from MFS
Background: The effectiveness of bevacizumab monotherapy in elderly patients with non-squamous non-small cell lung cancer (NSCLC) is unclear. The efficacy of the combinations for elderly patients was explored.
Nitrite ion is a by-product of nitrogen oxides (nitric oxide and nitrogen dioxide) from cigarette smoke and is used as a preservative for curing meats. Therefore, study of the reaction of nitrite with elastin in vitro was undertaken. By colorimetric assay, reactivity of nitrite with insoluble
The effects of abdominal operation on the antecubital vein plasma amino acid concentration were examined. With four groups, each containing ten patients, factors such as severity of surgical operation, anesthesia, and postoperative nutrition were examined. Immediately after operation there is a fall
We examined the pathogenic significance of VEGF (vascular endothelial growth factor)-A in experimental abdominal aortic aneurysms (AAAs) and the translational value of pharmacological VEGF-A or its receptor inhibition in aneurysm suppression. Approaches and Results: AAAs were created B-class ephrins, ligands for EphB receptor tyrosine kinases, are critical regulators of growth and patterning processes in many organs and species. In the endothelium of the developing vasculature, ephrin-B2 controls endothelial sprouting and proliferation, which has been linked to vascular
