Development of acceptable quality radiation dose levels for common computed tomography examinations: a focused multicenter study in united arab emirates
Elshami, Wiam; Abuzaid, Mohamed; Joseph, Dlama Z.; Tekin, H. O.; Ghonim, Hatem (FRONTIERS MEDIA SA, 2022)PurposeDiagnostic Reference Level (DRL) is a practical tool for radiation dose optimization, yet it does not indicate the patient size or image quality. The Acceptable Quality Dose (AQD) introduced to address the limitations ... -
A focusing study on radioprotective and antioxidant effects of Annona muricata leaf extract in the circulation and liver tissue: clinical and experimental studies
Elmas, Ozlem; Sahin, Havva Hande Keser; Guven, Berrak; Abuzaid, Mohamed M.; Elshami, Wiam; Almisned, Ghada; Zakaly, Hesham M. H.; Ene, Antoaneta; Tekin, Huseyin Ozan (De Gruyter Open Ltd, 2022)Objectives: This study investigates the effect of Annona muricata (AM) leaf extract against irradiation-induced damage by the evaluation of hepatic tissue and the levels of oxidative and inflammatory stress in the circulation. ... -
Multiple assessments on the gamma-ray protection properties of niobium-doped borotellurite glasses: A wide range investigation using Monte Carlo simulations
Tekin, H. O.; Ali, Fatema T.; Almisned, Ghada; Susoy, Gulfem; Issa, Shams A. M.; Ene, Antoaneta; Elshami, Wiam; Zakaly, Hesham M. H. (HINDAWI, 2022)In this study, the monotonic effect of Ta2O5 and ZrO2 in some selected borotellurite glasses was investigated in terms of their impact on gamma-ray-shielding competencies. Accordingly, three niobium-reinforced borotellurite ... -
