Here we report the draft genome sequence (6.6 Mbp) of the type strain Clostridium magnum, an acetogen with two operons coding for two separate Rnf complexes. C. magnum grows on a broad range of organic substrates and converts CO2 and H2 to acetate using the Wood-Ljungdahl pathway.
BACKGROUND Identification of high-grade meningiomas in preoperative magnetic resonance imaging (MRI) is important for optimized surgical strategy and best possible resection. Numerous studies investigated subjectively determined morphological features as predictors of tumor biology in meningiomas. The aim of this study was to identify the predictive value of more reliable, quantitatively measur...
Meningiomas are common tumors, constituting about 20% of all primary brain tumors.[4] The histological subtype of lipomatous meningioma, resulting from lipid accumulation within meningothelial cells, is a well‐described but uncommon entity, representing approximately 0.3% of meningiomas.[2,3] In the World Health Organization (WHO) classification of tumors of the nervous system (2000), meningiom...
Citation: GENC A, Kasapoglu B. Meningiomas of the Third Ventricle in Childhood. Neurosurg. 2016, 1:2. Intraventricular meningiomas are rare and relatively more often seen in children. Most often, these arise from the lateral ventricular walls. On the other hand, meningiomas of the third ventricle are extremely unusual and difficult to diagnose [1]. Those meningiomas arising in the third ventric...
Meningioma, a neoplasm derived from meningothelial cells, is one of the most common neoplasms in the central nervous system. Although certain types of meningiomas are associated with aggressive clinical behavior, majority of meningiomas appear to be benign. 2) Meningiomas are generally slowly growing tumors and produce neurological signs and symptoms either by compression of adjacent structures...
Meningiomas are common benign tumors accounting for 13% to 18% of intracranial neoplasms. They are generally known to be solid tumors and their classical appearance on the computed tomography(CT) scan and magnetic resonance(MR) image usually lead to a correct diagnosis. Meningiomas have been subdivided into a variety of types, including meningotheliomatous, fibrous, transitional, psammomatous, ...
Meningiomas are the most common type of primary brain tumors, accounting for about 30% of all brain tumors. Meningiomas originate from the meninges and can be associated with any part of the skull. Classification of meningiomas is based upon the World Health Organization (WHO) classification system and prognosis of meningiomas can be determined via histologic grading. Surgery is the gold standa...
Meningiomas are mostly benign brain tumours, with a potential for becoming atypical or malignant. On the basis of comprehensive genomic, transcriptomic and epigenomic analyses, we compared benign meningiomas to atypical ones. Here, we show that the majority of primary (de novo) atypical meningiomas display loss of NF2, which co-occurs either with genomic instability or recurrent SMARCB1 mutatio...
BACKGROUND AND PURPOSE Abnormal flow of CSF through the foramen magnum has been implicated in the pathogenesis of clinical deficits in association with Chiari I malformation. The purpose of this study was to test the hypothesis that peak CSF velocities in the foramen magnum are increased in patients with Chiari I malformations. METHODS Eight adult patients with symptomatic Chiari I malformati...
