Endothelial progenitor cells (EPCs) participate in renal repair, but their number and function may be impaired by exposure to cardiovascular risk factors. The number of circulating EPCs is decreased in essential and renovascular hypertensive patients, but the effects of hypertension on EPC function are incompletely understood. We hypothesized that EPC function was preserved under well-controlle...

Background Atherosclerotic renal artery stenosis (ARAS) is associated with high blood pressure (BP), decreased kidney function, renal replacement therapy (RRT), and death. Purpose To compare benefits and harms of percutaneous transluminal renal angioplasty with stent placement (PTRAS) versus medical therapy alone in adults with ARAS. Data Sources MEDLINE, EMBASE, and Cochrane Central Regist...

INTRODUCTION According to the non-specific presentation of atherosclerotic renal artery stenosis (ARAS), this disease is usually an under-diagnosed in clinical conditions. OBJECTIVES The aim of the presence study was to evaluate the prevalence of renal artery stenosis (RAS) and its related risk factors in hypertensive patients undergoing coronary angiography. PATIENTS AND METHODS In a cross...

Renovascular disease, especially atherosclerotic renal artery stenosis (ARAS) in older subjects, is commonly encountered in clinical practice. This is at least in part due to the major advances in non-invasive imaging techniques that allow greater diagnostic sensitivity and accuracy than ever before. Despite increased awareness of ARAS, renal revascularization is less commonly performed, likely...

Atherosclerotic renal artery stenosis has a range of manifestations depending on the severity of vascular occlusion. The aim of this study was to examine whether exceeding the limits of adaptation to reduced blood flow ultimately leads to tissue hypoxia, as determined by blood oxygen level dependent MRI. We compared 3 groups of hypertensive patients, 24 with essential hypertension, 13 with "mod...

In this paper, an asynchronous pipeline instruction simulator, ARAS is presented. With this sim-ulator, one can design selected instruction pipelines and check their performance. Performance measurements of the pipeline connguration are obtained by simulating the execution of benchmark programs on the machine architectures developed. Depending on the simulation results obtained by using ARAS, t...

BACKGROUND AND OBJECTIVES Trans-stenotic pressure gradient across the constriction (PG), a hemodynamic variable of atheromatous renal artery stenosis (ARAS), is a widely used indicator for angioplasty, but its association with the outcome of angioplasty has not been fully investigated. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS In 34 hypertensive cases with unilateral ARAS, we evaluated hem...

RATIONALE We report on a patient with hypersomnia who showed injury of the lower ascending reticular activating system (ARAS) following cerebellar herniation due to a cerebellar infarct, detected on diffusion tensor tractography (DTT). PATIENT CONCERNS A 53-year-old male patient was diagnosed as a left cerebellar infarct, and underwent decompressive suboccipital craniectomy due to brain edema...

This study included 126 hypertensive patients with renal artery stenosis (mean age, 63 years; 22.2% fibromuscular dysplasia [FMD]) and investigated the effects of percutaneous transluminal renal angioplasty on office and home blood pressure (BP), and BP variability estimates derived from home BP, both at baseline and up to 12 months after angioplasty. Home BP was measured for 7 consecutive days...
