Radiation is one of the main treatment modalities in lung cancer, but low sensitivity and acquired resistance of lung cancer cells to radiation frequently result in treatment failure. The activation of nuclear factor (NF)-κB is reportedly the main mechanism by which cancer cells exhibit resistance to external stresses, such as chemotherapy or radiation therapy. In this study, we blocked the act...

the harmful effects of the long-term ocular exposure to cumulative levels of infrared radiation (ir) in glassblowing and foundries have been recognized since the late 19th century. these effects include cataracts, keratitis, and chronic dry eye problems. therefore, infrared radiation measurements are critical and need to be assessed regularly in the industries and workplaces where there are hig...

malignant tumors of head and neck carcinomas are the sixth most common type of cancer. current systemic therapies for cancer show side effects in normal tissues and short-term efficacy due to drug resistance. consequently, there is much interest in identifying new drugs for cancer treatment. crocin (an active ingredient of saffron) has been shown to have cytotoxic effects on cancer cell lines. ...

The variability of radiation responses in ovarian tumors and tumor-derived cell lines is poorly understood. Since both DNA repair capacity and p53 status can significantly alter radiation sensitivity, we evaluated these factors along with radiation sensitivity in a panel of sporadic human ovarian carcinoma cell lines. We observed a gradation of radiation sensitivity among these sixteen lines, w...
