Introduction: We aimed to dosimetrically compare three-dimensional conformal radiotherapy (3D-CRT) and volumetric modulated arc therapy (VMAT) in terms of planning target volume (PTV) coverage, organ at risk (OAR) sparing, and conformity index (CI). Material and Methods: Planning data of 26 high grade glioma (HGG) patients were used. Prescrib...
PURPOSE Pseudoprogression (PsP) can mimic true tumor progression (TTP) on magnetic resonance imaging in patients with glioblastoma multiform (GBM). The phenotypical similarity between PsP and TTP makes it a challenging task for physicians to distinguish these entities. So far, no approved biomarkers or computer-aided diagnosis systems have been used clinically for this purpose. METHODS To add...
objective:glioblastoma is an invasive tumor of the central nervous system. epigenetic therapy of cancer is potentially very useful in reversing some of cancer defects due to reversibility of epigenetic alterations. meg3 is a tumor suppressor long non-coding rna (lncrna) that expresses in the majority of normal tissues. methylation of the meg3 promoter region elicits a decrease in its expression...
A simple theory of the covariant derivatives, deformed derivatives and relative covariant derivatives of multivector and multiform fields is presented using algebraic and analytical tools developed in previous papers.
We present a high-precision numerical study of 3D random percolation viewed as a confining gauge theory. Using large correlation matrices among multiform Wilson loops we determine the low-lying masses in various spin channels.
Inflammation has been closely related to various forms of brain tumors. However, there is little knowledge about the role of inflammation in glioma. Grade IV glioma is formerly termed glioblastoma multiform (GBM). GBM is responsible for over 13,000 deaths per year in the America. Magnetic resonance imaging (MRI) is the most commonly used diagnostic method for GBM tumors. Recently, use of the MR...
background: in 1997 mmac1 or the pten gene, was identified as a tumor suppressor gene on the long arm of chromosome 10.pten involves in the balance between proliferation, and differentiation, apoptosis and regulation of angiogenesis, and eventually mutation in this gene causes a strong potential for tumorigenesis cells. this study is the first report of the correlation between pten gene mutatio...
