RATIONALE No study on the association of absent-mindedness and injury of the ascending reticular activating system (ARAS) has been reported. We report on a patient who showed absent-mindedness and injury of the ARAS following mild traumatic brain injury. PATIENT CONCERNS The patient complained of absent-mindedness since the head trauma, which was mainly observed while dining for several (5-10...

BACKGROUND MicroRNAs (miRs) are small non-coding RNAs that are important regulators of gene expression and have been implicated in atherosclerosis. Kidney injury distal to atherosclerotic renal artery stenosis (ARAS) is aggravated by atherosclerosis. Therefore, this study tested the hypothesis that renal miR expression would be altered in patients with ARAS. METHODS Patients with essential hy...

BACKGROUND Atherosclerotic renal artery stenosis (ARAS) and coronary artery disease (CAD) commonly co-exist. Some patients with unidentified ARAS may undergo cardiac surgery. While acute kidney injury (AKI) is a frequent and serious complication of cardiac surgery, we aim to evaluate the influence of ARAS on the occurrence of postoperative AKI in patients with normal or near-normal baseline ren...

Many studies have reported about injury of the ascending reticular activating system (ARAS) in patients with various brain pathologies, using diffusion tensor tractography (DTT); however, little is known about injury of the ARAS in patients with pontine hemorrhage. In this study, using DTT, we attempted to investigate injury of the lower ventral and dorsal ARAS in patients with pontine hemorrha...

BACKGROUND Atherosclerotic renal artery stenosis (ARAS) is common in cardiovascular diseases and associated with hypertension, renal dysfunction and/or heart failure. There is a paucity of data about the prevalence and the role of ARAS in the pathophysiology of combined chronic heart failure (CHF) and chronic kidney disease (CKD). We investigated the prevalence in patients with combined CHF/CKD...

BACKGROUND We hypothesized that plasma levels of brain natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) would be elevated, and adiponectin concentrations reduced, in patients with atherosclerotic renal artery stenosis (ARAS) and that BNPs might be used to identify patients who would benefit from percutaneous transluminal renal angioplasty (PTRA). METHODS Data were collected before...

N-arachidonoyl-L-serine (AraS) is a novel neuroprotective endocannabinoid. We aimed to test the effects of exogenous AraS on neurogenesis after traumatic brain injury (TBI). The effects of AraS on neural progenitor cells (NPC) proliferation, survival, and differentiation were examined in vitro. Next, mice underwent TBI and were treated with AraS or vehicle. Lesion volumes and clinical outcome w...

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...
