A recently developed Centroidal Voronoi Tessellation (CVT) sampling method is investigated here to assess its suitability for use in response surface generation. CVT is an unstructured sampling method that can generate nearly uniform point spacing over arbitrarily shaped Mdimensional parameter spaces. For rectangular parameter spaces (hypercubes), CVT appears to extend to higher dimensions more...
Cerebral venous sinus thrombosis (CVT) can affect all age groups, particularly women of childbearing age. Overall prognosis for survival and functional independence is better than it was believed. Mortality usually ranges from 6-15% and transtentorial herniation is the major cause of death. Approximately 80% of patients are functionally independent in the long term. Altered mental status and ce...
BACKGROUND Cerebral venous thrombosis (CVT) is a rare disease and it has different etiologies. Inherited or acquired prothrombotic state plays a key role in the development of CVT. METHODS A 28-year-old man who presented to our emergency department with persistent headache and accompanied by complaints of nausea and vomiting over a week. Neurologic examination revealed bilateral papilledema. ...
INTRODUCTION Cerebral venous thrombosis (CVT) is a rare cerebrovascular condition accounting for <1% of all stroke cases and mainly affects young adults. Its genetic aetiology is not clearly elucidated. METHODS AND ANALYSIS To better understand the genetic basis of CVT, we have established an international biobank of CVT cases, Biorepository to Establish the Aetiology of Sinovenous Thrombosis...
BACKGROUND AND PURPOSE Cerebral venous thrombosis (CVT) may be a manifestation of underlying autoimmune disease. Antibodies against annexin A2 (anti-A2Ab) coincide with antiphospholipid syndrome, in which antiphospholipid antibodies (aPLA) are associated with thrombosis in any vascular bed. Annexin A2, a profibrinolytic receptor and binding site for β2-glycoprotein-I, the main target for aPLA, ...
To survive starvation conditions, eukaryotes have developed an evolutionarily conserved process, termed autophagy, by which the vacuole/lysosome mediates the turnover and recycling of non-essential intracellular material for re-use in critical biosynthetic reactions. Morphological and biochemical studies in Saccharomyces cerevisiae have elucidated the basic steps and mechanisms of the autophagy...
The present study aimed to summarize the clinical characteristics and experiences of misdiagnoses of cerebral venous thrombosis (CVT). A total of 18 patients with CVT who received treatment between September 2009 and August 2011 were enrolled. Of the patients, 13 were females and 5 were males with an average age of 39 years. Clinical manifestations and characteristics according to cerebrospinal...
INTRODUCTION The aim of this study was to review the clinical, computed tomography (CT) and magnetic resonance imaging (MRI) diagnosis and the frequency of positive neuroimaging findings in patients with cerebral venous thrombosis (CVT) involving the superior sagittal sinus. MATERIALS AND METHODS A clinical and radiological database of patients with final diagnosis of CVT was compiled from th...
OBJECTIVE Cerebral venous thrombosis (CVT) is a rare condition for which few clinical reviews have been conducted in Korea. Our aim was to investigate, risk factors, clinical presentations/courses, and outcomes of 22 patients treated for CVT at two centers. MATERIALS AND METHODS A retrospective analysis was conducted, selecting 22 patients diagnosed with and treated for CVT at two patient car...
BACKGROUND It has been estimated that 1.3-6.4% of patients with inflammatory bowel diseases (IBD) are complicated by cerebral venous thrombosis (CVT) at some point of time during the course of their disease. METHODS We retrospectively reviewed and subsequently analyzed data from 65 case reports of IBD patients with CVT. Our sources included MEDLINE and EMBASE, and the references of retrieved ...
