Redox Modifications and Hematological Neoplasms-an Overview

Article history Received: 05-02-2014 Revised: 06-08-2014 Accepted: 05-01-2015 Abstract: Due to our current interest in the study of the relationship between hematological malignancies and oxidative stress, in this review we addressed the recent finding regarding this issue, focusing on the clinical findings concerning the oxidative status of patients diagnosed with hematological cancers. This s...

Image Optimization in Single Photon Emission Computed Tomography by Hardware Modifications with Monte Carlo Simulation

Introduction: In Single Photon Emission Computed Tomography (SPECT), the projection data used for image reconstruction are distorted by several factors, including attenuation and scattering of gamma rays, collimator structure, data acquisition method, organ motion, and washout of radiopharmaceuticals. All these make reconstruction of a quantitative SPECT image very difficult. Simulation of a SP...

An Overview of the Epigenetic Modifications of Gene Expression in Tumorigenesis

The five leading causes of cancer-related deaths are lung (1,760,000 deaths), colorectal (862,000 deaths), stomach (783,000 deaths), liver (782,000 deaths), and breast (627,000 deaths) cancers. Epigenetic changes can alter chromatin compaction, leading to the regulation of geneexpression without changing the primary DNA sequence.Epigenetic mechanisms are normally involved incellular processes s...
