BACKGROUND AND PURPOSE Most DTI studies in ALS have been limited to the assessment of the CST damage. In this study, we used DTI tractography to investigate whether microstructural abnormalities occur in the major motor and extramotor WM tracts in mildly disabled patients with ALS. MATERIALS AND METHODS Brain conventional MR imaging and DTI were performed in 24 patients with probable or defin...

Objectives: Corticospinal tract (CST) is the most important tract in motor control. However, there was no study about the change of CST location with aging. In this study, using diffusion tensor tractography (DTT), we attempted to investigate the change of CST location at cortex, corona radiata (CR) and posterior limb of internal capsule (IC) level with aging in typically developing children. M...

BACKGROUND AND AIM Individuals with ischemia during cardiac stress-test (cST) have a high risk of developing myocardial infarction (MI), but the pathophysiologic mechanism has never been clarified. It is thought that non flow-limiting coronary plaques (FLP) cause more often MI than FLP, but this is in contradiction with the predictive value of cST. We investigated the correspondence between rev...

We use data on interbank loans and the core equilibrium concept to examine the efficiency of an overnight interbank lending market, and the bargaining power of its participants. In the specific case of Canada’s Large-Value Transfer System, we show that while the market is fairly efficient, systemic inefficiency persists throughout our sample. The level of inefficiency matches distinct phases of...

Background: Carbapenems (CAR), colistin (CST), and tigecycline (TGC) alone or in combination therapy has become the last-resort antibiotics for treating infections caused by multidrug resistant (MDR) bacteria. However, resistance to these reserve antibiotics are increasingly being reported worldwide. Hence, the quest to find other agents that will synergistically restore the efficacy of these a...

OBJECTIVES To evaluate the reliability and validity of measures taken during the Chester step test (CST) used to predict VO(2)max and prescribe subsequent exercise. METHODS The CST was performed twice on separate days by 7 males and 6 females aged 22.4 (SD 4.6) years. Heart rate (HR), ratings of perceived exertion (RPE), and oxygen uptake (VO(2)) were measured at each stage of the CST. RESU...

We introduce CST (cross-document structure theory), a paradigm for multidocument analysis. CST takes into account the rhetorical structure of clusters of related textual documents. We present a taxonomy of cross-document relationships. We argue that CST can be the basis for multidocument summarization guided by user preferences for summary length, information provenance, cross-source agreement,...

Pathological cardiac hypertrophy was produced by partial abdominal aortic constriction (PAAC) for 4 wk, while physiological cardiac hypertrophy was produced by chronic swimming training (CST) for 8 wk in rats. Pentoxifylline (30 mg/kg, 300 mg/kg i.p., day) treatment was started three days before PAAC and CST and it was continued for 4 wk in PAAC and 8 wk in CST experimental model. The left vent...

BACKGROUND AND PURPOSE Cavernous sinus thrombosis (CST) is a rare life-threatening cerebrovascular disease known to cause carotid artery narrowing (CAN) and arterial ischemic stroke. The imaging features of CST and related complications have been reported in adults, but rarely in children. METHODS We performed a retrospective review of children with imaging confirmed CST from 2003 to 2014, de...
