Ionizing radiations are known to challenge the integrity of the genome, by inducing several lesions like double strand breaks, single strand breaks and oxidative base damages in the DNA. Eukaryotic DNA is packaged inside the nucleus in the form of chromatin, which is formed by the interaction of histone proteins with DNA. Higher order chromatin structure acts as a barrier to the detection and r...
Cancer treatment and treatment options are quite limited in circumstances such as when the tumor is inoperable, in brain cancers when the drugs cannot penetrate the blood-brain-barrier, or when there is no tumor-specific target for generation of effective therapeutic antibodies. Despite the fact that electromagnetic fields (EMF) in medicine have been used for therapeutic or diagnostic purposes,...
Rhabdomyosarcomas (RMS) are aggressive childhood soft-tissue malignancies deriving from mesenchymal progenitors that are committed to muscle-specific lineages. Despite the histopathological signatures associated with three main histological variants, termed embryonal, alveolar and pleomorphic, a plethora of genetic and molecular changes are recognized in RMS. Over the years, exposure to carcino...
Oscillometry records the high frequency electrical activity on the skin surface. These are induced by external ambient electromagnetic radiations, and generated internally by physiological processes. The existence of these surface A.C. oscillations is fundamental to the existence of an electromagnetic field around the human body. Unfiltered electrical and inductive signals are digitally recorde...
BACKGROUND Implementation of X-ray dental examination is associated with the patients exposure to ionizing radation. The size of the exposure depends on the type of medical procedure, the technical condition of the X-ray unit and selected exposure conditions. The aim of this study was to determine the dose received by patients during dental X-ray examination and the assessment of the technical ...
The rapid development of technologies using static magnetic fields particularly in medicine has resulted in an increase in human exposure to very high static magnetic fields. ICNIRP is the internationally recognised body that sets guidelines for protection against adverse health effects of non-ionizing radiation including static magnetic fields. It has recently published guidelines on limiting ...
Physics is the science that studies the interaction between matter and energy. This discipline studies the general properties of bodies, the forces that modify the transfer of energy and the interaction between particles. Physics now has many branches, and one of them is the Biomedical Physics. Biomedical Physics in Medicine applies the principles and methods of physics. This will generate new ...
IOLOGICAL damage resulting from radiation treatment has been studied in a B number of biological systems (LEA 1947; HOLLAENDER 1954; BARQ and ALEXANDER 1955). ZIRKLE (1954) discussed the implications of the observed influence of linear energy transfer upon biological damage. More recently BURCH ( 195 7) has discussed several problems of relative biological efficiency with respect to the methods...
