Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disease defined by a low platelet count secondary to accelerated platelet destruction by anti-platelet antibodies. The resulting bleeding diathesis can present a therapeutic dilemma. We have treated two cases of ITP in which ureteral stones were successfully extracted by transurethral ureterolithotripsy (TUL) and extracorporeal shock wa...

the aim of present study was to investigate the potential antioxidant and lung protective activities of sambucus ebulus (se) against toxicity induced by gamma irradiation. hydro alcoholic extract of se (20, 50 and 100 mg/kg ) was studied for its lung protective activity. . phenol and flavonoid contents of se were determined. male c57 mice were divided into 10 groups with five mice per group. on...

Background: In some areas of Ramsar, a city in northern Iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. Induction of adaptive response in residents of Ramsar has been reported previously. In this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. Materials and M...

background: whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. the main goal of this study was to assess the role of 900 mhz microwave radiations with different specific absorption rates (sars), emitted from some widely used cell phones, on the induction of adaptive response in male balb/c mice after receiving a lethal dose of gamma ...

The purpose of this study was to evaluate the effectiveness of full three-dimensional (3D) gamma algorithm for spot scanning proton fields, also referred to as pencil beam scanning (PBS) fields. The difference between the full 3D gamma algorithm and a simplified two-dimensional (2D) version was presented. Both 3D and 2D gamma algorithms are used for dose evaluations of clinical proton PBS field...

Background: Exposure to ionizing radiation is inevitable. Using of low-level laser therapy (LLLT) stimulates tissue repair and reduces inflammation. The objective of the present study aimed at evaluating the therapeutic efficacy of Helium-Neon (He-Ne) laser in stimulating the reparative processes in the liver of mice after whole body gamma-irradiation (WBγ-I). Materials and Methods: Two hundred...

the aim of this study is to provide a control software system, based on monte carlo simulation, and calculations of dosimetric parameters of standard and wedge radiation fi elds, using a monte carlo method. gate version 6.1 (opengate collaboration), was used to simulate a compact 6 mv linear accelerator system. in order to accelerate the calculations, the phase-space technique and cluster compu...

Introduction: Active personal dosimeters (APDs) are well accepted as useful and reliable instruments for individual dosimetry measurements. APDs have many advantages compared with passive dosimeters for individual external radiation dose assessments. In routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. So, ...

Calvarial reconstruction following resection of tumors involving the skull is often followed by stereotactic radiosurgery. Prior studies have addressed the effects of various cranioplasty materials on dose distributions in linac-based radiosurgery. We aim to determine the effects of titanium mesh implants on Gamma Knife dose. Radiation backscatter and transmission were measured for eight types ...
