Out of different soil samples from neutral environments 50 thermo-acidophilic bacilli were isolated. All 23 strains tested contain ω-cyclohexane fatty acids in the range of 15–91% of the total fatty acids. In this group six strains possess hopane containing lipids (hopanoids). In contrast Bacillus coagulans, sometimes described as thermoacidophilic,(More)
BACKGROUND Central nervous system (CNS) hemangioblastomas are a benign condition, which can be permanently cured by complete surgical removal. However, the vascular nature of these lesions and difficulties in localizing the tumors account for operative morbidity and recurrence. Power Doppler flow sonography has been proven useful during surgical removal of(More)
Leptomeningeal metastasis (LM) of high grade gliomas (HGG) can lead to devastating disease courses. Understanding of risk factors for LM is important to identify patients at risk. We reviewed patient records and magnetic resonance imaging (MRI) of all patients with a first diagnosis of HGG who underwent surgery in our institution between 2008 and 2012. To(More)
BACKGROUND AND PURPOSE Cerebral infarction is a frequent and serious complication of aneurysmal subarachnoid hemorrhage (SAH). This study aimed to identify independent predictors of the timing of cerebral infarction and clarify its impact on disease course and patients' outcome. METHODS All consecutive patients with SAH admitted to our institution from(More)
BACKGROUND Neurogenic polyglobulia occurs with central nervous system hemangioblastomas. Among the suggested mechanisms are extramedullary hematopoiesis in the tumor tissue and germline mutations of the von Hippel-Lindau (VHL) tumor suppressor gene. OBJECTIVE To determine the frequency and driving mechanisms of polyglobulia in central nervous system(More)
CT-angiography gains an increasing role in the initial diagnosis of patients with nontraumatic subarachnoid hemorrhage (SAH). However, the implementation of CT-angiography does not always exclude the necessity of conventional angiography. Our objective was to determine the practical utility and cost-effectiveness of CT-angiography. All patients with(More)
