CVT-E002 (a proprietary extract) was found to be effective in the prevention of upper respiratory infections (URIs) in healthy adults, and institutionalized and community-dwelling seniors. A multicenter, randomized, double-blind, placebo-controlled trial was carried out to determine effects of CVT-E002 in the prevention of URIs in influenza-vaccinated community-dwelling adults. 783 community-dw...

Recent studies suggest that thrombophilic abnormalities and the use of oral contraceptives (OCs) are the leading causes of cerebral vein thrombosis (CVT). The purpose of this study was to assess the association between CVT and thrombophilic states, OCs, and their interaction. For data sources, we used the MEDLINE, EMBASE, and Cochrane Library databases (January 1994 to March 2005), reference li...

The incidence of cerebral venous thrombosis (CVT) is estimated at 0.2 to 0.5 per 100 000 per year. One estimate was derived from an extrapolation of mortality and autopsy data from studies performed several decades ago. Kalbag and Woolf provide mortality figures from the British Registrar General. From 1952 to 1961 an average of 21.7 deaths from CVT were reported annually in a population of 56 ...

Background. The causes of cerebral venous thrombosis (CVT) are manifold as is its clinical presentation. Case. We report the case of a CVT following lumbar puncture and intravenous glucocorticosteroid therapy in a female adolescent with a clinically isolated syndrome and risk factors for thrombosis. Conclusion. In adolescent patients with acute inflammatory disease undergoing lumbar puncture fo...

Most existing applications of centroidal Voronoi tessellations (CVTs) lack consideration of the length of the cluster boundaries. In this paper we propose a new model and algorithms to produce segmentations which would minimize the total energy — a sum of the classic CVT energy and the weighted length of cluster boundaries. To distinguish it with the classic CVTs, we call it an Edge-Weighted CV...

We herein report a young patient with cerebral venous thrombosis (CVT) with clinical and neuroradiological findings of the left maxillary and anterior ethmoid sinusitis. Serial brain MRIs showed cerebral venous infarct and thrombosis in the superior sagittal sinus (SSS). MR angiography demonstrated nonvisualization of SSS and bilateral transverse sinus. According to our knowledge, CVT associate...

Cerebral venous thrombosis (CVT) has been reported as an uncommon and devastating complication of ulcerative colitis (UC), with an annual incidence varying between 0,5 to 6,7%. It is suspected to be a consequence of the hypercoagulable state occurring during disease relapse. We report a case of 22-year-old female patient presenting with CVT revealing an UC. Our case raises the awareness among h...

We present a novel surface mesh segmentation algorithm that, when combined with the Centroidal Voronoi Tessellation (CVT) remeshing method, produces surface meshes that more closely approximate the input surface mesh than when using CVT alone, using both topological and geometric measures of closeness. By segmenting the input surface before CVT remeshing, fewer triangles are required for the re...

Abstract Capacitive Voltage Transformer (CVT) is an important measurement and protection equipment in power system, which has the characteristics of high electrical strength, large insulation margin reliable operation. During operation CVT, its upper lower capacitors, compensation reactors, lightning rods other components often have faults. The faults CVT can be found time by judging secondary ...
