A comprehensive set of measurements and calculations has been conducted to investigate the accuracy of the Dose Planning Method (DPM) Monte Carlo code for dose calculations from 10 and 50 MeV scanned electron beams produced from a racetrack microtron. Central axis depth dose measurements and a series of profile scans at various depths were acquired in a water phantom using a Scanditronix type R...
PHARMACOKINETIC PROFILE OF TETRAPRENYLTOLUQUINONE AFTER SINGLE-DOSE ORAL ADMINISTRATION IN MALE MICE
Objective: The aim of this study to investigate pharmacokinetic profile tetraprenyltoluquinone (TPTQ) in male mice’s blood plasma.
 Methods: A single dose 800 mg/kg carried by Virgin Coconut Oil (VCO) was given orally where VCO only also administered as a control. Bloods were collected from vena jugularis after 0, ½, ¾, 1, 1½, 2, 3, 4, 6, 8, 12, and 24 h. TPTQ levels plasma analyzed using ...
background: this work investigated the dosimetry limitations of the random and systematic uncertainties of sliding window (sw) intensity modulated radiation therapy (imrt). materials and methods: a varian 21ex linear accelerator, pinnacle3 treatment planning system and radiographic film dosimetry was used. the limitations of the sw were studied using beam modulation ranging from 2 to 100 mu/bea...
Veliparib (ABT-888) is a potent, orally bioavailable poly(ADP-ribose) polymerase-1 and -2 inhibitor. This phase 1 study evaluated the tolerability, pharmacokinetic profile, safety, and preliminary antitumor activity of single-agent veliparib in Japanese patients with advanced solid tumors. Eligible patients were assigned to treatment with veliparib at 200 or 400 mg dose; veliparib was self-admi...
the monte carlo method can be used to describe any technique that approximates solutions to quantitative problems through statistical sampling. this method is considered to be the most accurate method for dose calculation in radiotherapy. for complete modeling of a linear accelerator, it is required that the manufactured information covers all data, but some data such as primary electron energy...
introduction: esophageal cancer is one of the most frequently occurring cancers in iran and having a high incidence rate among other countries. radiotherapy is one of the three methods (surgery, radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. in this method of treatment, the organs such as heart and spinal cord are regarded as organs at r...
introduction radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. therefore, entrance skin dose (esd), body organ dose (bod), and effective dose (ed) from adult patients undergoing routine thorax posterior-anterior (pa) and thorax right lateral (rlat) were estimated in uni...
