introduction: clinical radiation nephropathy can result in considerable morbidity and/or mortality. renal tolerance (td5/5) has been stated to be 20 gy when irradiation has been delivered to both kidneys in 3-5 weeks. therefore to minimize renal toxicity in these patients, localization and shielding of the kidneys are essential. this study was carried out to evaluate the role of 99mtc-dtpa rena...
intravenous laser blood irradiation was first introduced into therapy by the soviet scientists en.meschalkin and vs.sergiewski in 1981. originally this method was developed for the treatment of cardiovascular diseases. improvement of rheologic properties of the blood as well as improvement of microcirculation and reduction of the area of infarction has been proved. further, reduction of dysrhyt...
in the present study, aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 w for 2-7 min in high yields. the amidrazone hydroiodide can also be prepared by the reaction of s-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. all synt...
Background Conventional radiotherapy for painful spinal metastases can be delivered with a single posterior-anterior (PA) or two opposed anterior-posterior (APPA) fields. We studied the effectiveness and toxicity of both techniques and studied whether treatment technique was predictive for abdominal and skin toxicity. Patients and methods Within the Dutch Bone Metastasis Study, 343 patients r...
background: organophosphorus pesticides are one of the most consumable poisons. such poisons can enter water sources by different routes. since consuming some drinking water containing an amount of poison higher than the standard level, causes undesirable effects on human health. this research aimed to study the effectiveness of eliminating malathion from water by ultraviolet irradiation (uv) ...
Treatment for bilateral breast cancer with chest wall and abdominal skin invasion normally involves conventional radiotherapy (RT); however, conventional RT provides inadequate target volume coverage and excessive treatment of large volumes of normal tissue. Helical tomotherapy (HT) has the ability to deliver continuous craniocaudal irradiation that suppresses junction problems and provides goo...
