<h3>Objective</h3> The radiological characteristics of World Health Organization grade III oligodendroglial tumours in relation to chromosome 1p and 19q deletions were analysed. <h3>Methods</h3> 56 patients recently diagnosed with anaplastic oligodendroglioma (AO, n=49) or oligoastrocytoma (AOA, n=7) studied. Their preoperative magnetic resonance images examined. Deletions determined using the fluorescence situ hybridisation method. Both chromosomes had (1p19q codeletion) 39 (36 AO 3 AOA)....

Recent interest has focused on whether South Korea may have undergone variable tectonic rotations since the Cretaceous. In an effort to contribute answer this question, we completed a palaeomagnetic reconnaissance study of Early Cretaceous sedimentary and igneous rocks from Kyongsang basin in southeast Korea. Stepwise thermal demagnetization isolated well-defined characteristic magnetization all samples. The directions reveal patterns increasing amounts clockwise (CW) rotation with age for...

However, we try to assess the characteristic features and recurrences of CMEC pediatric patients according stages, determine value preoperative computed tomography (CT) scan. Retrospective review 35 cases under age 15 yr that had been treated at tertiary referral center from 1995 through 2006. The main outcome measures were CT findings, surgical recurrence rate hearing assessment. Preoperative scan...
