association between elf and rf electromagnetic field and leukemia

چکیده
extremely low frequency (elf) electromagnetic field (elf-emfs) are widely employed in electrical appliances and different equipment such as television sets, elf-emfs can affect biological systems by increasing production ros. the altered balance between ros generation and elimination plays a critical role in a variety of pathologic conditions. ros levels have been observed in several hematopoietic malignancies including acute and chronic myeloid leukemia. elf-emfs exposure significantly decreased nitric oxide synthase (inos) protein expression lower levels of no have been demonstrated to exert a protective function in leukemic and melanoma cells and to inhibit effector caspases by s-nitrosylation. also elf-emfs can decrease melatonin production by effects on n-acetyltransferase. melatonin is an antioxidant, effective in protecting nuclear dna. transmitters emitting radio frequency electromagnetic fields (rf-emfs) are usually not located in populated areas but some epidemiology studies showed association distance transmitters from residential area and leukemia.

Calcium ions play many important roles in biological systems. For example, calcium ion activity can be used as an indicator of second-messenger signal-transduction processes in cells. Intracellular stores of calcium are housed in the mitochondria, the endoplasmic reticulum and other membrane structures, and in calmodulin molecules, and are released upon triggering by signaling events that alter...

15 صفحه اولRF Electromagnetic Field Treatment of Tetragonal Kesterite CZTSSe Light Absorbers
In this work, we propose a method to improve electro-optical and structural parameters of light-absorbing kesterite materials. It relies on the application of weak power hydrogen plasma discharges using electromagnetic field of radio frequency range, which improves homogeneity of the samples. The method allows to reduce strain of light absorbers and is suitable for designing solar cells based o...
