Effects of Ionizing Radiation on Luminous Bacteria Cells
نویسندگان
چکیده
Marine luminous bacteria were used to monitor toxicity of alpha(Am-241, U-235+238) and beta(tritium) radionuclide solutions. Increase or inhibition of bacterial luminescence was observed under exposure to radionuclides. Radiation toxicity of Am and chemical toxicity of U were demonstrated. Effects of U were similar to those of stable heavy metals: sensitivy was about 10M. Sensitivity of the bacteria to Am-241 was 300 Bq/L (10M). Inhibition of bacterial growth was observed under exposure to Am-241 and tritium. Role of peroxides and electron transfer processes in the effects of radionuclides on luminous bacteria is discussed.

Effects of gamma radiation on adipose-derived mesenchymal stem cells of human breast tissue
Background: During radiation therapy, stromal cells surrounding the tumor (e.g mesenchymal stem cells) may affect the treatment outcomes. We aimed to investigate the effects of gamma radiation on the mRNA expression of cytokines, DNA damage and population doubling time (PDT) of adipose-derived mesenchymal stem cells (ASCs). Material and methods: ASCs were enzymatically extracted from breast tis...

متن کاملAtorvastatin Sensitizes Breast and Lung Cancer Cells to Ionizing Radiation
Tumour cells may be resistant to radiotherapy that results in unsuccessful cancer treatment in patients. The aim of this study was to evaluate the sensitizing effect of atorvastatin (ATV) on breast cancer (MDA-MB-231) and non-small cell lung cancer (A-549) cells following exposure to ionizing radiation (IR). These cells were treated with ATV and exposed to X-ray at dose 4 Gy. The radiosensitizi...
