Evaluation of some blood parameters alteration following low-dose radiation induced by Myocardial Perfusion Imaging
Purpose: With increasing the usage of myocardial perfusion imaging (MPI) for the diagnosis of ischemic heart disease, we aimed to evaluate the side effects of low-dose radiation induced by this technique on blood elements, especially proteins and liver function factors.Materials and Methods: 40 eligible patients (Mean age: 54.6...
متن کاملEvaluation of Breast Cancer Radiation Therapy Techniques in Outfield Organs of Rando Phantom with Thermoluminescence Dosimeter
Background: Given the importance of scattered and low doses in secondary cancer caused by radiation treatment, the point dose of critical organs, which were not subjected to radiation treatment in breast cancer radiotherapy, was measured.Objective: The purpose of this study is to evaluate the peripheral dose in two techniques of breast cancer radiotherapy with two energies. Methods: Eight diff...
متن کاملLocal-Reference Patient Dose Evaluation in Conventional Radiography Examinations in Mazandaran, Iran
Background:The most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate. Â Objective: The present study is aimed at initially establishing a baseline for local-reference dose level in Mazandaran, Iran in 12 projections of the...
متن کاملAliphatic/Aromatic Amino Acid Pairings for Polyamide Recognition in the Minor Groove of DNA
Selective placement of an aliphatic â-alanine (â) residue paired side-by-side with either a pyrrole (Py) or imidazole (Im) aromatic amino acid is found to compensate for sequence composition effects for recognition of the minor groove of DNA by hairpin pyrrole-imidazole polyamides. A series of polyamides were prepared which contain pyrrole and imidazole aromatic amino acids, as well as γ-aminob...
متن کاملIsolation and identification of a stabilized derivative of aldophosphamide, a major metabolite of cyclophosphamide.
homoalcophosphamide by the procedure of Corey and Kim (7) gave diethylaldophosphamide and diethylhomoaldophos phamide, respectively (Chart 2). Diethylaldophosphamide was characterized by mass spectral analysis [m/e 283, 1 Cl, M2— CH2C1@; m/e 192, no Cl, M —N(CH2CH2C1)2] and by positive qualitative tests as an aldehyde and an alkylating agent. Complete purification of diethylaldophosphamide ...
