Evaluating the Radioactive Waste Produced per Patient by Radiopharmaceutical Sources and Measuring the Radioactive Contamination of Surfaces and Staff at the Bushehr Nuclear Medicine Department.

Background: Nuclear medicine is an integral and developing field in diagnosing and treating diseases. Monitoring individuals' protection and radiation contamination in the workplace is vital for preserving working environments.

Objective: This study aimed to monitor the nuclear medicine department's personnel, environment, and wastes to determine the level of occupational radiation and environmental pollution in Bushehr's nuclear medicine department.

Investigating the Expression Levels of Bax and Bcl-2 Genes in Peripheral Blood Lymphocytes of Industrial Radiation Workers in the Asaluyeh Region.

Background: Industrial radiography uses gamma or X-ray radionuclide sources to investigate the safety of industrial materials. Industrial radiation workers receive the highest occupational radiation doses.

Objective: The present study investigates the relationship between Bax and Bcl-2 gene expression variables in industrial radiation workers.

Extremely Low Frequency-Electromagnetic Fields (ELF-EMF) Can Decrease Spermatocyte Count and Motility and Change Testicular Tissue.

Background: Substantial evidence indicates that exposure to extremely low frequency-electromagnetic fields (ELF-EMFs) affects male reproductive system.

Objective: The goal of this study was to evaluate the effects of long-term irradiation with ELF-EMF on sperm quality and quantity and testicular structure.

Material And Methods: In this case-control study, sixty male Sprague-Dawley rats were randomly divided into six groups.

Hesperidin Modulates Troponin-1 Serum Level and Decrease Heart Tissue Injury of Irradiated Rats.

Background: The heart is the major dose-limiting organ for radiotherapy of malignant tumor in the mediastanal region.

Objective: This study aims to investigate the radio protective effects of Hesperidin (HES) as a natural flavonoid after localized irradiation of the rat's mediastinum region.

Material And Methods: In this experimental study, we divided sixty male rats into 4 groups (n=15).

Design and validation of a hospital emergency department preparedness questionnaire for radiation accidents, nuclear accidents, and nuclear terrorism in Iran.

Background And Objectives: Radiation accidents can cause numerous challenges to hospitals, the appropriate medical responses to which may save the lives of countless people. The present study aimed at the design and validation of an Emergency Department preparedness questionnaire for hospital emergency departments (EDs) in the case of radiation accidents, nuclear accidents, and nuclear terrorism in Iran.

Materials And Methods: This multistage cross-sectional study was conducted in 2019.

Protection effect of cerium oxide nanoparticles against radiation-induced acute lung injuries in rats.

Introduction: Radiation therapy is one of the most common tools for treating cancer. The aim is to deliver adequate doses of radiation to kill cancer cells and the most challenging part during this procedure is to protect normal cells from radiation. One strategy is to use a radioprotector to spare normal tissues from ionizing radiation effects.

Developing a Model for Hospitals' Emergency Department Preparedness in Radiation and Nuclear Incidents and Nuclear Terrorism in Iran.

Objective: To develop a national model for hospitals' Emergency Department (ED) preparedness when facing radiation and nuclear incidents as well as nuclear terrorism in Iran.

Methods: This analytical study was carried out in 2019 via Delphi technique in two rounds and prioritization using a pairwise questionnaire. Using classic Delphi technique and pairwise comparison, the components were given to 32 specialists in emergency medicine, nuclear medicine, medical physics, nuclear physics, radiobiology and radiation protection, health in disaster and emergency, and passive defense.

Evaluation of the effect of hesperidin on vascular endothelial growth factor gene expression in rat skin animal models following cobalt-60 gamma irradiation.

Introduction: Skin is highly prone to radiation damage. Radiation burn is defined as damage to the skin or other biological tissues induced by radiofrequency or ionizing radiation. Vascular endothelial growth factor (VEGF) is a heparin-binded pro-angiogenic factor.

Expression of Bax and Bcl2 Genes in Peripheral Blood Lymphocytes of Patients with Differentiated Thyroid Cancer.

Context: Thyroid cancer is the most common endocrine malignancy worldwide. Iodine-131 is used in the treatment of thyroid cancer with dosage of 100 mCi. In the medical applications of ionizing radiation besides the advantages such as diagnosis and treatment of diseases, the risks arising from exposure should be considered as well.

Radioprotective effect of melatonin on the cervical spinal cord in irradiated rats.

Objective: It has been suggested that the vascular endothelial growth factor (VEGF) gene expression plays an important role in radiation-induced injury to the spinal cord. This study assesses the radioprotective effects of N-acetyl-5-methoxytryptamine (melatonin) through its modulation of VEGF expression after localized irradiation of the cervical spinal cord.

Materials And Methods: In this experimental study, we divided 192 male rats into four groups: 1.
