chemokines are biologically active peptides involved in the pathogenesis of various pathologies including brain malignancies. they are amongst primitive regulators of the development of immune responses against malignant glial tumors. the present study aimed to examine the expression of cc chemokines in anaplastic astrocytoma and glioblastoma multiform patients at both mrna and protein levels. ...
Glioblastoma multiform (GBM) is the most common and malignant form of glial tumors. GBM microenvironment contains various cell types showing characteristics of activated or dimorphic macrophages/microglia. Some of these cells provide significant help for tumor growth, while others are able to inhibit tumor progression. Microglia play a major role in brain function by monitoring tissue for patho...
Objective: Radiomics-driven Computer Aided Diagnosis (CAD) has shown considerable promise in recent years as a potential tool for improving clinical decision support in medical oncology, particularly those based around the concept of Discovery Radiomics, where radiomic sequencers are discovered through the analysis of medical imaging data. One of the main limitations with current CAD approaches...
brain tumors in elderly are increasing as the number of people, who comprise the older population, does.about half of the patients with brain tumors appear to be over 60 years of age.in this review article, glioblastoma multiform, as the most common malignant tumor of the central nervous system in elderly is discussed in details of definition, prognosis, diagnosis, treatment and differential di...
Six patients whose standard electrocardiograms showed multiform ventricular ectopic rhythm were studied. All patients had advanced organic heart disease and a significant intraventricular conduction defect (left bundle branch block in five and right bundle branch block plus left anterior hemiblock in one). The ventricular arrhythmia was generally resistant to antiarrhythmic therapy. Five of the...
Medical imaging plays a fundamental role in oncology and drug development, by providing a non-invasive method to visualize tumor phenotype. Radiomics can quantify this phenotype comprehensively by applying image-characterization algorithms, and may provide important information beyond tumor size or burden. In this study, we investigated if radiomics can identify a gefitinib response-phenotype, ...
Medical imaging can visualize characteristics of human cancer noninvasively. Radiomics is an emerging field that translates these medical images into quantitative data to enable phenotypic profiling of tumors. While radiomics has been associated with several clinical endpoints, the complex relationships of radiomics, clinical factors, and tumor biology are largely unknown. To this end, we analy...
Human cancers exhibit strong phenotypic differences that can be visualized noninvasively by medical imaging. Radiomics refers to the comprehensive quantification of tumour phenotypes by applying a large number of quantitative image features. Here we present a radiomic analysis of 440 features quantifying tumour image intensity, shape and texture, which are extracted from computed tomography dat...
