Using the combined results of oral and intravenous xylose tests, it is demonstrated that 26% of a group of geriatric patients absorb from the small bowel less efficiently than younger subjects. The method used excludes poor renal function and incomplete bladder emptying as possible causes for the differences found between the two age groups. Altered gastric emptying is also excluded as a possib...

background: annual patient effective dose equivalent can be considered as a quantitative physical parameter describing the activities performed in each nuclear medicine department. annual staff dose equivalent could be also considered as a parameter describing the amount of radiation risk for performing the activities. we calculated the staff to patient dose equivalent ratio to be used as a phy...

Objective(s): Pioglitazone (Actos) is one of the most controversial recent oral antidiabetic drugs. It was originally authorized in the European Union in 2000, and approved as an oral monotherapy for overweight second type of diabetic patients in 2002. It belongs to the thiazolidinedione group which some of its members have been withdrawn from the market due to the hepatotoxicity or cardiotoxic...

Introduction: Intensity Modulated Radiotherapy (IMRT) is a common method for treating prostate cancers. Different IMRT methods can apply for irradiating the prostate, but there is not clear that which of these methods can provide better dose distribution for each patient individually. Therefore, the aim of this study was to evaluate the relationship between the different prosta...

ADAPTIVE RADIATION THERAPY OF PROSTATE CANCER by NING WEN August 2010 Advisor: Dr. Teamour Nurushev Major: Medical Physics Degree: Doctor of Philosophy ART is a close-loop feedback algorithm which evaluates the organ deformation and motion right before the treatment and takes into account dose delivery variation daily to compensate for the difference between planned and delivered dose. It also ...

conclusions bladder perforation and stones are rare examples of complications in v-p surgical procedures. controlling the effective length of the terminal v-p shunt and modifying it appropriately can effectively reduce these complications. case presentation we report on a 38-year-old male who had hydrocephalus and v-p shunt for 12 years. two years ago, he found himself with recurrent urinary tr...

objective: investigating some biological side effects of radiations resulted from fusion reaction experiments in damavad tokamak. materials and methods: the absorbed dose of the personnel in damavand tokamak was measured using lif dosimeters and analyzed. results: in damavand in areas near the forbidden zone around this device the level of the received dose is very high (more than 6 msv for eac...

PURPOSE The aim of this study is to compare 3D dose volume histogram (DVH) parameters of bladder and other organs at risk with different bladder filling protocol during high-dose-rate intracavitary brachytherapy (HDR-ICBT) in cervical cancer, and to find optimized bladder volume. MATERIAL AND METHODS This dosimetric study was completed with 21 patients who underwent HDR-ICBT with computed tom...
