Abstract Cerebral venous (sinus) thrombosis (CVT) is an unusual manifestation of causing severe neurological impairment and seizures 1,2 . Molecular mechanisms underlying CVT, potentially involving pathological platelet activation, are unknown. Here we show that antibody-(INU1-fab)-induced cooperative signaling two receptors, C-type lectin-like receptor-2 (CLEC-2) GPIIb/IIIa, triggers within mi...
در طول تاریخ صنایع خودروسازی تلاش های گسترده ای برای طراحی اجزای خودرو به شکلی که سبب کاهش تولید آلاینده ها و افزایش بازده خودرو گردد صورت گرفته است. چون تولید آلاینده ها به طور مستقیم به نرخ مصرف سوخت وابسته است، هر پیشرفتی که در راستای بهبود بازده خودرو صورت می گیرد، منجر به کاهش میزان تولید آلاینده ها می شود. یکی از مؤثرترین سامانه ها در این راستا، سامانه انتقال قدرت با نسبت دور متغیر پیوسته...
background: muslim women tend to postpone their menstrual period using short course oral contraceptives (oc) during ramadan, muslims fasting month. recently, many cases of stroke, particularly cerebral vein thrombosis (cvt), have been reported in ramadan. objective: this work studies the incidence of cvt and its relation to ramadan. materials and methods: this is a cohort study conducted from o...
در این مقاله، به منظور دستیابی به مصرف سوخت کمینه در خودروهای مجهز به سامانه انتقال قدرت cvt ، با در نظر گرفتن اتلاف توان در اجزای مختلف سامانه انتقال قدرت مجهز به cvt در شرایط مختلف رانندگی و عوامل موثر در آن، الگوی جامعی برای پایش سامانه انتقال قدرت ارائه شده است. با توجه به پویائی خودرو، موتور و سامانه انتقال قدرت، دستیابی به مصرف سوخت کمینه به یک مسأله پایش بهینه منجر می شود که برای حل آن ا...
Cerebral venous thrombosis (CVT) is an uncommon cause of stroke with diverse etiologies and varied clinical presentations. Because of variability in clinical presentation and neuroimaging, CVT remains a diagnostic challenge. Recently, some studies have highlighted the value of T2∗-weighted gradient-echo MRI (T2∗WI) in the diagnosis of CVT. We report the case of a 79-year-old woman with CVT due ...
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, ...
