The Grid2003 Project has deployed a multivirtual organization, application-driven grid laboratory ("Grid3") that has sustained for several months the production-level services required by physics experiments of the Large Hadron Collider at CERN (ATLAS and CMS), the Sloan Digital Sky Survey project, the gravitational wave search experiment LIGO, the BTeV(More)
BACKGROUND There are still controversies about long-term clinical outcomes of sirolimus-eluting stents (SES) versus bare metal stents (BMS) implantation in patients with end-stage renal diseases (ESRD). OBJECTIVE To compare long-term outcomes in patients with (ESRD) following SES versus BMS implantation. METHODS Between March 2003 and July 2005, a total(More)
Recently, we showed that disturbed flow caused by a partial ligation of mouse carotid artery rapidly induces atherosclerosis. Here, we identified mechanosensitive genes in vivo through a genome-wide microarray study using mouse endothelial RNAs isolated from the flow-disturbed left and the undisturbed right common carotid artery. We found 62 and 523 genes(More)
The fate of coronary artery aneurysms (CAAs) caused by Kawasaki disease depends mainly on their initial size and shape. Small to medium-sized CAAs are known to regress to normal size or decrease in size, with a good outcome. A patient with Kawasaki disease is reported who had a medium-sized CAA prematurely occluded with thrombi during regression, resulting(More)
RATIONALE GTP cyclohydrolase I (GTPCH-1) is the rate-limiting enzyme involved in de novo biosynthesis of tetrahydrobiopterin (BH(4)), an essential cofactor for NO synthases and aromatic amino acid hydroxylases. GTPCH-1 undergoes negative feedback regulation by its end-product BH(4) via interaction with the GTP cyclohydrolase feedback regulatory protein(More)
Bone marrow mesenchymal stem cells (MSCs) have shown potential for cardiac repair following myocardial injury, but this approach is limited by their poor viability after transplantation. To reduce cell loss after transplantation, we introduced the fibroblast growth factor-2 (FGF-2) gene ex vivo before transplantation. The isolated MSCs produced colonies(More)
We examined the protective effect of unsorted human adipose tissue-derived stem cells (hADSCs) with a short-term culture in endothelial differentiation medium on tissue repair after ischemic injury. hADSCs were isolated from human subcutaneous adipose tissue and cultured in vitro in endothelial differentiation medium for 2wks before transplantation.(More)
Quantitative measurement of functional tissue perfusion is essential for early diagnosis and proper treatment of peripheral arterial occlusive disease (PAOD). We have previously demonstrated that dynamic imaging of near-infrared fluorophore indocyanine green (ICG) can be a noninvasive and sensitive tool to measure tissue perfusion. In the present study, we(More)
BACKGROUND Accurate measurement of peripheral tissue perfusion is challenging but necessary to diagnose peripheral vascular insufficiency. Because near infrared (NIR) radiation can penetrate relatively deep into tissue, significant attention has been given to intravital NIR fluorescence imaging. METHODOLOGY/PRINCIPAL FINDINGS We developed a new optical(More)
A naturally occurring bile acid, ursodeoxycholic acid (UDCA), is known to alleviate endoplasmic reticulum (ER) stress at the cellular level. However, the detailed action mechanisms of UDCA in atherosclerosis are not fully understood. In this study, we demonstrated whether UDCA exerts anti-atherogenic activity in diabetic atherosclerosis by targeting ER(More)
