Introduction Radiation that has sufficient energy to remove electrons from atoms is called “ionizing radiation.” Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two groups: photons (includes X-radiation and gamma radiation) and particles (includes alpha and beta particles and neutrons). The...

AIM To characterize the interaction of tumour necrosis factor alpha (TNF-alpha) and ionising radiation in six sarcoma, lymphoma and carcinoma cell lines. MATERIALS AND METHODS Cells were characterized regarding annexin V/propiduim iodine affinity and caspase-3 status after application of TNF-alpha, radiation, or combined treatment. RESULTS Three cell lines showed similar results with additi...

To date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 MHz microwave radiation, originating from the handsets or the base transceiver stations, have been released. The current study was designed for evaluation of 900-MHz radiation effects on Candida albicans proliferatio...

PURPOSE Radiation-induced lung toxicity limits the delivery of high-dose radiation to thoracic tumors. Here, we investigated the potential of inhibiting the tumor necrosis factor-alpha (TNF-alpha) pathway as a novel radioprotection strategy. EXPERIMENTAL DESIGN Mouse lungs were irradiated with various doses and assessed at varying times for TNF-alpha production. Lung toxicity was measured by ...

Ionizing radiation is electromagnetic radiation that has sufficient energy to remove electrons from atoms. Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two categories: photons (X-radiation and gamma radiation) and particles (alpha and beta particles and neutrons). Five types or sources o...

Recent studies have proposed that tumor necrosis factor alpha (TNF-alpha) and ionizing radiation induce apoptosis by activating hydrolysis of sphingomyelin to ceramide. Bcl-2 and a related gene, Bcl-X, inhibit several forms of apoptosis. Herein, we report that internucleosomal DNA fragmentation, characteristic of apoptosis and induced by ionizing radiation, is accompanied by concomitant decreas...

The unexpected nuclear accidents have provided a challenge for scientists and engineers to develop sensitive detectors, especially for alpha radiation. Due to the high linear energy transfer value, sensors designed to detect such radiation require placement in close proximity to the radiation source. Here we report the morphological changes and optical responses of artificially designed DNA thi...
