Alfalfa in dry stress conditions cannot grow optimally. Drought inhibits growth and reduces alfalfa production many cultivation systems. Plants breeding with gamma-ray irradiation vitro selection using PEG found somaclonal variants adapted to well drought conditions. This study aims determine the type of mutation best morphology mutants resulting from gamma were sub-cultured vitro. cultured med...

Background Stereotactic radiotherapy (SRT) should be applied with a biologically effective dose an ?/? of 12 (BED12) ? 40 Gy to reach 1-year local control (LC) 70%. The aims this retrospective study were report series 81 unresected large brain metastases treated Linac-based multifraction SRT according the ICRU 91 and identify predictive factors associated LC. Methods Included in first (BM) cons...

irradiation is known to inhibit waste in stored garlic. treatment time and optimum irradiation dosage are two key factors in achieving the least waste in this process. these two factors were investigated on white ecotype bulbs from hamedan, iran that were irradiated after harvest for 30 and 45 days using fast electrons at dosages of 0, 25, 50, 75, 100, and 150 gy. different properties of the ga...

We evaluated radiation-induced myocardial damage using iodine-123 β-methyl-iodophenyl pentadecanoic acid (I-123 BMIPP) scintigraphy. Between May 2010 and April 2011 we performed I-123 BMIPP scintigraphy for patients who had maintained complete response to curative radiotherapy (RT) for esophageal cancer for more than six months. We compared the area of the myocardium in the RT fields with that ...

Background: Breast-conserving surgery (BCS) followed by radiotherapy (RT) is the standard of care for women with breast cancer. Evidence shows that RT dose to the heart can result in ischemic heart disease. In this study we compared 3 different RT techniques were for heart, left anterior descending coronary artery (LAD) and lung doses in left breast cancer patients after breast-conserving surge...

Three radiation protocols currently used in treatment of leukemia patients before bone marrow transplantation (BMT) were investigated in a murine model (C57BL/6----C3H/HeJ) for BM allograft rejection. These include (a) a single dose of total body irradiation (8.5 Gy TBI delivered at a dose rate of 0.2 Gy/min), (b) fractionated TBI (12 Gy administered in six fractions, 2 Gy twice a day in 3 days...

A randomized trial of 12.0 Gy versus 15.75 Gy of total body irradiation (TBI) was performed in patients with acute myeloid leukemia undergoing allogeneic marrow transplantation while in first complete remission. All patients received 120 mg/kg cyclophosphamide followed by TBI and marrow from HLA-identical siblings. Cyclosporine and methotrexate were used for prophylaxis against acute graft-vers...
