The centroidal Voronoi tessellation (CVT) has found versatile applications in geometric modeling, computer graphics, and visualization, etc. In this paper, we first extend the concept of CVT from Euclidean space to spherical space and hyperbolic space, and then combine all of them into a unified framework – the CVT in universal covering space. The novel spherical and hyperbolic CVT energy funct...

Background and Purpose—Isolated lateral sinus thrombosis was long considered a complication of middle ear disease. Little attention has been recently paid to this variety of thrombosis. We therefore reviewed all cases of isolated lateral sinus thrombosis prospectively collected in our center (1997 to 2006). Methods—Among 195 patients with cerebral venous thrombosis (CVT), we identified 157 pati...

Although CVT is associated with a good outcome in the majority of cases, it may be complicated by numerous unique and sometimes rare complications. The purpose of this review is to discuss the acute and chronic complications of CVT in greater detail. Awareness may lead to a more aggressive approach in those in which these complications are anticipated and perhaps avoided. The complications of C...

abstract: a continuously variable transmission (cvt) is a transmission which may change step less by way of an infinite variety of effective gear ratios between maximum and minimum values. this contrasts with different mechanical transmissions that solely permit just a few different distinct gear ratios to be selected. continuously variable transmissions (cvts) are mechanical devices that allow...

background: anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (cvt). however, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician. methods: this was a prospective observational study on consecutive cvt patients with hemorrhagic venous infarction or subarachnoid hemorrha...

ABSTRACT Objectives: This study aims to report the outcomes of patients with Behçet’s disease (BD) with cerebral venous thrombosis (CVT) due to BD compared to patients with CVT due to other causes and to discuss the treatment options. Patients and methods: Files of 47 patients admitted to our outpatient clinic for CVT between January...

Administration of the selective adenosine A1 receptor antagonist, CVT-124, to conscious chronically instrumented rats resulted in significant increases in urine flow rate and sodium excretion without affecting potassium excretion or renal hemodynamics. Its maximum effect was twice that of hydrochlorothiazide which was associated with a significant kaliuresis. The diuretic effect of CVT-124 was ...

Malignancy is known to be one of the predisposing factors of cerebral venous thrombosis (CVT) due to its hypercoagulable state. CVT is a rare disorder which can lead to frequent misdiagnoses of brain metastases in such cases. We report here the case of a 35-year-old female with metastatic colon adenocarcinoma presenting with sudden neurological symptoms. Brain MRI and magnetic resonance venogra...

CVT-E002, a proprietary extract from North American ginseng (Panax quinquefolium) showed immunomodulating activity. Cytochrome P450 (CYP), UDP-glucuronosyl transferase (UGT), and glutathione S-transferase (GST) are important drug-metabolizing enzymes. Modulation of drugmetabolizing enzymes is a main cause of drug interactions. To assess the possible metabolism-based drug interaction of CVT-E002...

BACKGROUND The parasympathetic nervous system has been implicated in the pathogenesis of a number of gastrointestinal disorders including irritable bowel syndrome. Within the field, cardiometric parameters of parasympathetic/vagal tone are most commonly derived from time, or frequency, domain analysis of heart rate variability (HRV), yet it has limited temporal resolution. Cardiac vagal tone (C...
