Coronary artery bypass grafting (CABG) is among the most commonly performed heart surgical procedures. Saphenous vein graft failure due to stenosis impedes the longer-term success of CABG. A key cellular event in the process of vein graft stenosis is smooth muscle cell hyperplasia. In this study, we evaluated the effect ...

Co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to terrestrial life that couples cardiac output with the gas exchange function of the lung. Here we show that the murine pulmonary vasculature develops even in the absence of lung development. We have identified a population of multipotent ...

In the α1,3-galactosyltransferase knockout (α-GalT KO) pig era, identification of the non-Gal epitopes is necessary for successful pig-to-human xenotransplantation. Recently, we successfully detected α-Gal epitopes as well as Hanganutziu-Deicher (H-D) antigens from the N-glycans in the pig heart tissues, which have been considered as promising non-Gal antigens. However, the profiling ...

Large increases in muscle sympathetic nerve activity (MSNA) can decrease the diameter of a conduit artery even in the presence of elevated blood pressure, suggesting that MSNA acts to regulate conduit artery tone. Whether this influence can be extrapolated to spontaneously occurring MSNA bursts has not been examined. Therefore, we ...

Under certain circumstances, the placement of arterial catheters can be difficult. In these instances, a form of guidance is preferred to avoid repeated insertions of the arterial catheter. Ultrasonic guidance is generally used in these instances, but the equipment required is expensive and cumbersome. This study produced an arterial catheter ...

During knee flexion, the muscles of the upper leg impose various loads on the underlying femoropopliteal artery resulting in radial compression, bending, torsion, axial extension and axial compression. Measuring the dynamic force environment of the femoropopliteal artery and quantifying its resulting deformation characteristics is an essential input to peripheral device ...

Abstract Background: Cardiovascular disease is the most common cause of death in patients with chronic kidney disease (CKD). Arterial stiffness and calcification are non-traditional risk factors of cardiovascular disease in CKD. In CKD rats, we investigated the involvement of smooth muscle cells differentiation to osteoblast-like cells and blood vessel wall ...

Endothelial-dependent regulation of vascular tone occurs in part via protein kinase G1α-mediated changes in smooth muscle myofilament sensitivity to Ca(2+). Tissue-specific differences in PKG-dependent relaxation have been attributed to altered expression of myofilament-associated proteins that are substrates for PKG binding. These include the alternative splicing of the myosin targeting subunit ...

We previously developed a cell-free, biodegradable scaffold for in-situ tissue-engineering vasculature (iTEV) in a canine inferior vena cava (IVC) model. In this study, we investigated application of this scaffold for iTEV of the pulmonary artery (iTEV-PA) in a canine model. In vivo experiments were conducted to determine scaffold characteristics and long-term ...

Aims: Chronic hypoxia induces pulmonary hypertension (PH) concomitant with pulmonary vascular remodeling. Reactive oxygen species (ROS) are thought to play a major role in this. Recent findings suggest that ROS production by NADPH oxidase 4 (Nox4) is important in this remodeling. We investigated whether ROS production by NADPH oxidases is ...

This review attempts to explain the controversies concerning the mechanism of shear stress mediated arterial dilatation, commonly called flow-mediated arterial dilatation (FMD). FMD occurs in an artery when the blood flow to the organ supplied by the artery is increased. There are two hypotheses about the stimulus for FMD: (1) ...

Approximately 1-2 per 1000 newborn babies have a cardiac defect that is potentially life-threatening usually because either the systemic or the pulmonary blood flow is dependent on a patent ductus arteriosus. A significant proportion of newborns with such cardiac defects are being discharged from well-baby nurseries without a diagnosis and ...

This investigation examined the mechanisms by which coronary perivascular adipose tissue (PVAT)-derived factors influence vasomotor tone and the PVAT proteome in lean versus obese swine. Coronary arteries from Ossabaw swine were isolated for isometric tension studies. We found that coronary (P=0.03) and mesenteric (P=0.04) but not subcutaneous adipose tissue augmented ...

BACKGROUND: Hypoxia may contribute to the pathogenesis of various diseases of the vascular wall. Hypoxia-inducible factors (HIFs) are nuclear transcriptional factors that regulate the transcription of genes that mediate cellular and tissue homeostatic responses to altered oxygenation. This article reviews the published literature on and discusses the role of the ...
