Background: Hydroxyurea (HU) is a well known chemotherapeutic agent that has been used largely for various myeloproliferative diseases over the past 20 years. In β-thalassemia, the effect of HU is much less clear and remains controversial. This study was undertaken to describe the hematologic and clinical responses of thalassemia major and intermediate patients to HU treatment during 2 years. M...

Introduction: In radiotherapy treatment planning system (TPS), basic input is the data from computed tomography (CT) scan, which takes into account the effect of inhomogeneities in dose calculations. Measurement of CT numbers may be affected by scanner-specific parameters. Therefore, it is important to verify the effect of different CT scanning protocols on Hounsfield unit (HU) and its impact o...

Cancer is a fatal disease and relatively widespread in the world; Breast cancer is the most prevalent cancer among women. Hydroxyurea (HU) is a chemotherapy drug for the cure of cancer different types in patients, for example breast cancer, but has several defects, for to remove these problems in this study a nanoliposome (NL) suspension for Hydroxyurea (HU) delivery in breast cancer cell thera...

background recent studies regarding the effect of hydroxyurea (hu) in thalassemia have revealed favorable effects on the reduction of ineffective erythropoiesis. objectives the aim of the current study was to evaluate whether or not hu can have an effect on the gallstone formation rate in patients with beta-thalassemia intermedia (bti). patients and methods in this case control cross-sectional ...

Background Sickle hemoglobin is the most common abnormal hemoglobin in the United States. Hemoglobin S arises as a result of a single amino acid substitution (glutamic acid to valin at position 6 of the β-globine chain). The presence of fetal hemoglobin (HbF) plays a relatively protective role since a significant amount of HbF interferes with HbS polymerization, the pathogenesis mechanism of ...

Background: The HU linearity is an essential parameter in a quantitative imaging and the treatment planning systems of radiotherapy. Objective: This study aims to evaluate the linearity of Hounsfield unit (HU) in applying the adaptive iterative dose reduction (AIDR) on CT scanner and its comparison to the filtered back-projection (FBP).Material and Methods: In this experimental phan...
