OBJECTIVES The aim of this study was to assess the impact of atherosclerotic renal artery stenosis (ARAS) on outcomes after open-heart surgery (OHS). BACKGROUND Acute kidney injury after OHS portends significant morbidity and mortality. METHODS Data from all adult patients undergoing OHS from January 2000 to April 2010 who underwent renal duplex ultrasound were prospectively collected. ARAS...

BACKGROUND Atherosclerotic renal artery stenosis (ARAS) can lead to end-stage renal failure (ESRF). We determined the prevalence of ARAS in patients 45 years of age or older starting renal replacement therapy. METHODS Forty-nine of 80 consecutive patients (37 males, 12 females) starting renal replacement therapy in our centre gave informed consent and underwent spiral computed tomographic ang...

Consciousness is mainly controlled by activation of the ascending reticular activating system (ARAS). Diffusion tensor tractography (DTT), which is reconstructed from diffusion tensor imaging (DTI) data, allows reconstruction and evaluation of the ARAS in the live human brain (Yeo et al., 2013; Jang et al., 2014; Jang and Kwon, 2015). Injury of the ARAS in various stroke pathologies including s...

AIMS To examine biomarkers of oxidative stress (oxs), and endothelin (ET)-1, in hypertensive patients with atherosclerotic renal artery stenosis (ARAS) and to evaluate the effect of percutaneous transluminal renal angioplasty (PTRA). METHODS Baseline measurements were made immediately before renal angiography in patients with suspected ARAS (significant ARAS, n = 83, and non-RAS, n = 59) and ...

BACKGROUND/AIMS The contribution of emergent cardiovascular risk factors to atherosclerotic renal artery stenosis (ARAS) is debated. We investigated the relationship of lipoprotein(a) and prothrombotic factors with ARAS in hypertension. METHODS In 50 hypertensive patients with angiographic evidence of ARAS and 58 hypertensive patients who had comparable cardiovascular risk factor burden but n...

PURPOSE Although multiple serum antiretinal autoantibodies (ARAs) have been reported in patients with paraneoplastic and non-paraneoplastic autoimmune retinopathy ((n)pAIR), not all retinal antigens involved in (n)pAIR are specified. This study aims to serologically identify patients with presumed (n)pAIR through determination of both known and unknown ARAs by autoantibody profiling. METHODS ...

We report on patients with post-traumatic fatigue and hypersomnia who showed injury of the lower portion of the ascending reticular activating system (ARAS) between the pontine reticular formation (RF) and the intralaminar thalamic nucleus (ILN) following mild traumatic brain injury (TBI), using diffusion tensor tractography (DTT).Two patients with mild TBI resulting from a car accident were en...

BACKGROUND The established risk factors for atherosclerotic renal artery stenosis (ARAS) include hypertension, diabetes mellitus, dyslipidemia, obesity, smoking, old age and family history. In the last few years, several emerging risk factors have been proposed as predictors of ARAS, namely homocysteine, fibrinogen, C-reactive protein, lipoprotein(a) and creatinine. METHODS We searched Pubmed...

Basal elements in archaeal promoters, except for putative initiator elements encompassing transcription start sites, are well characterized. Here, we employed the Sulfolobus araS promoter as a model to study the function of the initiator element (Inr) in archaea. We have provided evidence for the presence of a third core promoter element, the Sulfolobus Inr, whose action depends on a TATA box a...

INTRODUCTION Action of the ascending reticular activating system (ARAS) on the cerebral cortex is responsible for achievement of consciousness. In this study, we attempted to reconstruct the lower single component of the ARAS from the reticular formation (RF) to the thalamus in the normal human brain using diffusion tensor imaging (DTI). METHODS Twenty six normal healthy subjects were recruit...
