The increasing prevalence of atherosclerotic renal artery stenosis (ARAS) has prompted in recent years a more aggressive treatment of this condition for reducing BP and for preserving the jeopardized renal function. Percutaneous transluminal renal angioplasty (PTRA), alone or in conjunction with stent implantation, may be useful for both these goals. However, despite the methodological improvem...

Alport posttransplantation anti-glomerular basement membrane (GBM) nephritis is mediated by alloantibodies against the noncollagenous (NC1) domains of the alpha3alpha4alpha5(IV) collagen network, which is present in the GBM of the allograft but absent from Alport kidneys. The specificity of kidney-bound anti-GBM alloantibodies from a patient who had autosomal recessive Alport syndrome (ARAS) an...

BACKGROUND Atherosclerotic renal artery stenosis (ARAS) is known to reduce renal blood flow, glomerular filtration rate (GFR) and amplify kidney hypoxia, but the relationships between these factors and tubulointerstitial injury in the poststenotic kidney are poorly understood. The purpose of this study was to examine the effect of renal revascularization in ARAS on renal tissue hypoxia and rena...

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

It is known that sensory signals sustain the background discharge of the ascending reticular activating system (ARAS) which includes the noradrenergic locus coeruleus (LC) neurons and controls the level of attention and alertness. Moreover, LC neurons influence brain metabolic activity, gene expression and brain inflammatory processes. As a consequence of the sensory control of ARAS/LC, stimula...

PURPOSE To evaluate whether renal dimensions and the main renal artery (mRA) diameter can provide indirect evidence of the presence or absence of accessory renal arteries (aRA). MATERIALS AND METHODS The study group consisted of 167 patients (83 women, 84 men; mean age, 52.4±13.1 years) who presented to our radiology department for abdominal CT examinations with various indications. CT examin...

Background: In the patients with severe atherosclerotic renal artery stenosis (ARAS), the evaluation of long-term clinical outcome after percutaneous transluminal renal angioplasty (PTRA) has yet been insufficient. The aim of this study was to focus on only patients with severe ARAS and to evaluate the more long-term clinical outcome after PTRA. Methods: We performed a single-center retrospecti...

We reported on the ascending reticular activating system (ARAS) finding of a patient in whom severe injury of the cerebral cortex was detected following a hypoxic-ischemic brain injury (HIBI).A 67-year-old female patient who suffered from HIBI induced by cardiac arrest after surgery for lumbar disc herniation underwent cardiopulmonary resuscitation approximately 20 to 30 minutes after cardiac a...

OBJECTIVE To evaluate the effect of percutaneous transluminal renal angioplasty (PTRA) on split renal function (SRF) in patients with unilateral atherosclerotic renal artery stenosis (ARAS). METHODS We performed a retrospective analysis of all consecutively examined patients at our centre with significant ARAS undergoing PTRA during 2002-07. A significant ARAS was defined as a lesion with a t...
