Background: The beneficial effect of supplementing culture medium with melatonin has been reported during in vitro embryo development of species such as mouse, bovine and porcine. However, the effect of melatonin on the mouse somatic cell nuclear transfer remained unknown. Materials and Methods: In this study, we assessed the effects of various concentrations of melatonin (10-6 to 10-12 M) on t...

one of the most challenges of iran foreign policy during of 2003-2015 was iran nuclear program. in these years the governments of seyed mohamad khatami and mahmoud ahmadinejad tried to solve the problem of iran nuclear case but this important issue only realized in hasan rouhani government. the main question here is that what factors did influence on decision making of iran’s officials and acqu...

Background: People who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. The aim of this work was to estimate radiation dose received by nuclear medicine nurses. Materials and Methods: In this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...

solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...

Multifocal avascular osteonecrosis is an uncommon entity having a predominant association with steroids and less commonly with alcohol abuse. In literature only few cases of alcohol induced multifocal avascular osteonecrosis involving both hips and shoulder are reported. To the best of our understanding this is the first case report or contribution from nuclear medicine court and it would help ...

Background: The aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at Bahawalpur Institute of Nuclear Medicine and Oncology department. Materials and Methods: Annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to Radiation Dosimetry Laboratory (RDL), Pakistan Institute of Nuc...

  Background: CT scan and nuclear medicine exams deliver a great part of medical exposures. This study examined professional radiation hazards in CT scan and nuclear medicine workers.   Methods : In a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. Physical dosimetry was performed for exposed workers. Blood samples were ...
