OBJECTIVES P In vitro chemosensitivity and resistance assays (CSRAs) are a promising tool for personalized treatment of glioblastoma multiform (GBM). These assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. We aimed to assess the feasibility and validity of utilizing stereotactic biopsies of GBM in CSRAs. MATERIALS AND METHODS Single ...
BACKGROUND Immunohistochemical markers are considered as important factors in diagnosis of malignant astrocytomas. The aim of the current study was to investigate the frequency of the immunohistochemical markers neurofilament protein (NFP) and glial fibrillary acidic protein (GFAP) in malignant astrocytoma tumors in Firoozgar and Rasool-Akram hospitals from 2005 to 2010. MATERIALS AND METHODS...
Rearrangements concerning chromosome 9p are a late event in the progression of human astrocytic tumors to their most malignant form. The expression of PAX5, which maps to chromosome 9p13, was studied in primary human brain tumors of astrocytic origin. Whereas murine Pax5 is not expressed in the forebrain at any stage, PAX5 expression was increased in a range of astrocytomas (WHO grades II-IV) w...
Introduction: Advanced quantitative information such as radiomics features derived from magnetic resonance (MR) image may be useful for outcome prediction, prognostic models or response biomarkers in Glioblastoma (GBM). The main aim of this study was to evaluate MRI radiomics features for recurrence prediction in glioblastoma multiform. Materials and Methods:</str...
Background and Aim: Glioblastoma multiforme (GBM) is the most common malignant and invasive tumor of the brain. The relation between prognosis and survival of GBM patients with Epidermal Growth Factor Receptor (EGFR) expression is challenging. Thus, we aimed to evaluate the prognosis and survival of patients with GBM and its relationship with EGFR expression. Materials and Methods: This single...
We present, for the first time, a Lagrangian multiform complete Kadomtsev-Petviashvili (KP) hierarchy -- single variational object that generates whole and encapsulates its integrability. By performing reduction on this multiform, we also obtain multiforms Gelfand-Dickey of hierarchies, comprising, amongst others, Korteweg-de Vries Boussinesq hierarchies.
