On June 27–28, 2011, scientists from the National Cancer Institute (NCI), NASA, and academiamet in Bethesda to discuss major lung cancer issues confronting each organization. For NASA, available data suggest that lung cancer is the largest potential cancer risk from space travel for both men and women and quantitative risk assessment information formission planning is needed. In space, the radi...

Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. This review introduces the field of nanotechnology with a focus on recent gold nanoparticle research which has led to early-phase clinical trials. In particular, the pre-clinical evidence for gold nanoparticles as sensitis...

Lung cancer is a curable disease if detected early, and its mortality rate decreases with forwarding treatment measures. At first, an easy accurate way to detect by using image processing techniques on the cancer-affected images captured from patients. This paper proposes novel lung detection method. Firstly, adaptive median filter algorithm (AMF) applied preprocess those for improving quality ...

Background: Lung cancer is one of the most common cancers around the world, and a major cause of death. The KRAS and NRAS genes could cause malfunction in signal transduction and cell cycle regulation. Materials and Methods: In this study, the expression level of KRAS and NRAS biomarkers among 50 lung cancer patients in comparison with 50 normal individuals was investigated. Total RNA from blo...

Optically stimulated luminescent detectors, which are widely used in radiation protection, offer a number of potential advantages for application in radiation therapy dosimetry. Their introduction into this field has been somewhat hampered by the lack of information on their radiation response in megavoltage beams. Here the response of a commercially available optically stimulated luminescent d...
