AIM Characteristic of West Nile fever (WNF) virus strains circulating in southern Russia. MATERIALS AND METHODS WNF RNA was amplified directly from clinical samples, mosquitoes and bird tissues by PCR, nucleotides were sequenced directly and analyzed comparatively. RESULTS Related but different genovariants of WNF lineage 1a--"Volgograd" and(More)
Pilocytic astrocytoma (PA) is a low-grade glial tumor (WHO grade I) with predominant occurrence in pediatric patients. According to many authors, stereotactic radiosurgery (SRS) and radiotherapy (SRT) promote long-term remission or retardation of tumor progression in patients with in inoperable lesions after incomplete resection or recurrence. Therefore it(More)
We report a unique case of primary multiple liponeurocytoma. Liponeurocytoma is a rare benign tumor (Grade II) of the posterior cranial fossa with neural- or probably astrocytic-lineage cells; the tumor stroma contains mature adipocytes. This case is the thirty-eighth case of this pathology reported in the world literature and the first case of multiple(More)
BACKGROUND MicroRNAs (miRNAs) are a class of small non-coding RNA molecules involved in the regulation of key biological processes. Different miRNAs with pro-oncogenic and anti-oncogenic properties have been identified in glioblastomas. We decided to analyze expression profiles of 10 mature miRNAs (miR-7-1, miR-10а, miR-17, miR-20а, miR-21, miR-23а,(More)
THE AIM OF THE STUDY Paper describes a study of language lateralization of patients with brain tumors, measured by preoperative functional magnetic resonance imaging (fMRI) and comparison results with tumor histology and profile of functional asymmetry. METHODS During the study 21 patient underwent fMRI scan. 15 patients had a tumor in the left and 6 in(More)
INTRODUCTION Lhermitte--Duclos disease is a rare autosomal dominant inherited disorder characterized by the loss of the normal cerebellar cortex architecture and hamartoma formation in the cerebellar hemispheres. Most commonly, this disease manifests in the third and fourth decades of life. Approximately 220 cases of Lhermitte--Duclos disease have been(More)
We report three patients with intraparenchymal brainstem schwannomas that were confirmed by surgery and pathological examination: tumors originated from the midbrain parenchyma, the dorsal aspect of the pontomedullary junction and the medulla oblongata respectively. Two of the presented patients differed in age of disease presentation which may reflect(More)
Stereotactic radiosurgery (SRS) becomes more widely used in treatment of patients with intracranial tumors. In spite of low invasiveness this method produces risk of development of radiation-induced complications including symptomatic focal necrosis. Authors report a case of radiation-induced necrosis occurred in a patient treated for benign glioma using(More)
Embryonic tumor with abundant neuropil and true rosettes (ETANTR) is a very aggressive rare tumor with unique histologic and molecular features occurring in very young children. At present approximately 80 cases of ETANTR have been documented in the literature since first description in 2000. We report seven patients with ETANTR below 4 years of age who(More)
