Introduction: Delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. According to ICRU, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. Absorbed dose accuracy is investiga...

background: atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. oxidized low-density lipoprotein (oxldl) is considered as an important determining factor in the pathogenesis of atherosclerosis. objective: the purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

Introduction: One of the sources of natural occurring radiation was soils. The purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. Methods & Materials: The soil samples was located in Chahbahar city in Blouchestan of Iran, was chosen for studyin...

paclitaxel is a highly effective anticancer agent. it is active against a broad range of cancers that are generally considered refractory to conventional chemotherapy. paclitaxel induces a peripheral neuropathy (pn) that is characterized by sensory symptoms such as numbness and paresthesia in a glove and stocking distribution. pn may be severe and dose limiting at initial doses above 275 mg/m2....

background and objectives: patient safety culture is increasingly recognized as an essential driver of patient safety. to establish patient safety culture, firstly the current status of the construct should be assessed. valid assessment of patient safety culture is contingent on the availability of appropriate measurement tools. hospital survey on patient safety culture (hsops) developed by the...

Background: The present study intended to determine and report patient effective dose on the basis of patients and exposure data. Materials and methods: A nationwide computed tomography (CT) survey was provided as a report of patient doses in 2015-2016. Scan details were collected for nearly 2,000 adults and children in four age groups subjected to CT examinations. From total 565 CT scanners in...

 Background: Although some patients can tolerate colonoscopy procedure using fentanyl/ midazolam without any sedation and analgesic requirements but some patients may require additional sedation with benzodiazepines. We performed the present study to compare the effect of paracetamol/midazolam with fentanyl/ midazolam. Methods: In a clinical trial, 96 patients aged 18 to 75 years old, ...
