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...

Araştırmanın amacı OECD ülkelerinin, sağlık ekipmanları ve göstergeleri açısından belirlenen kriterlere göre sıralaması yapılarak; elde edilecek sıralamalar değerlendirilmesidir. Çalışmada Çok Kriterli Karar Verme Yöntemleri tercih edilmiştir. Bu kapsamda araştırmada kriter ağırlıklarının hesaplanmasında ENTROPİ yöntemi, ülkelerin sıralamasının yapılmasında ARAS SAW yöntemleri kullanılmıştır. A...

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...

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...
