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...

We examine how historic flooding in 2011 affected the geomorphic adjustments created by dam regulation along the approximately 120 km free flowing reach of the Upper Missouri River bounded upstream by the Garrison Dam (1953) and downstream by Lake Oahe Reservoir (1959) near the City of Bismarck, ND, USA. The largest flood since dam regulation occurred in 2011. Flood releases from the Garrison D...

Extensive development in the Canadian River watershed in New Mexico and Texas occurred in the 20 century to supply water for irrigation, and municipal and industrial uses. In recent years (2000-2009), these infrastructures have not been able to supply sufficient water to meet demands. The objective of this study was to assess the effects of changes in irrigation allotments and land use to the 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...

Percutaneous transluminal renal stenting (PTRS) does not consistently improve renal function in patients with atherosclerotic renovascular disease, but the mechanisms underlying irreversible kidney injury have not been fully elucidated. We hypothesized that renal dysfunction after PTRS is linked to ongoing renal microvascular (MV) remodeling. Pigs were studied after 10 wk of atherosclerosis and...
