The Effect of Oxygen on the Production by Fast Neutrons of Chromosomal Aberrations in Tradescantia Microspores.
HE studies of THODAY and READ (1947) using root-tip cells of Vicia T j a b a demonstrated that oxygen has a marked effect in increasing the frequency of X-ray-induced chromosome aberrations. These investigators later showed (1949) that when alpha rays are used, the oxygen effect is much less, since the yield of aberrations with oxygen present was only slightly greater than in its absence. In ex...
متن کاملComputational Model of Reaction Mechanism of Alkyl Peroxy Radicals with Organic Compounds in the Presence and Absence of Oxygen
On the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in Langmuir- Hinshelwood approach at room temperature has been offered.The effect of oxygen on the kinetics of process in the presence, [O2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. Over time the chain degenerate branching...
متن کاملInherent radiosensitivity and its impact on breast cancer chemo-radiotherapy
About 10% of apparently normal individuals are sensitive to clastogenic effects of physico-chemical agents. More than 45% of breast cancer patients’ exhibit elevated radiosensitivity. Although the nature of inherent radiosensitivity is not fully understood, but insufficiency and impaired DNA repair mechanism might be prime cause of radiosensitivity. This is evident from genetically affect...
متن کاملDihydroartemisinin increases radiosensitivity of A549 lung cancer cells
Background: Radiotherapy is the gold standard in the treatment of lung cancer. However, the radiosensitization of cancerous cells requires further improvement. Here, we investigated the effect of dihydroartemisinin (DHA) on the radiosensitization of non-small cell lung cancer (NSCLC) cells. Methods: Cell proliferation and cell cycle assays were carried out using A549 cells exposed to DHA. The e...
متن کاملUse of Apoptotic Biomarkers to Predict Response to Radiotherapy in Breast Cancer Patients
Introduction: To enhance radiation therapy efficiency it is crucial to implement an individual-based treatment. The aim of present study was to identify the mechanism of intrinsic apoptosis pathway on radiosensitivity and normal tissue complications caused by the radiotherapy. Materials and Methods: radiation-induced apoptosis in periphera...
