Radiosensitivity is the relative susceptibility of cells, ... Amongst the body cells, ... secondary cancer is the most important.
Another important observation is that oxygen must be present at irradiation or within milliseconds afterward for the oxygen effect to take place. [ 8 ] The best known explanation of the oxygen effect is the oxygen fixation hypothesis developed by Alexander in 1962, [ 9 ] which posited that radiation-induced non-restorable or "fixed" nuclear DNA ...
Radiation sensitivity is the susceptibility of a material to physical or chemical changes induced by radiation. [1] Examples of radiation sensitive materials are silver chloride, photoresists and biomaterials.
However, since alpha particles cannot traverse the outermost dead layer of human skin, they can do significant damage only if they come from the decay of atoms inside the body. Since the range of an alpha particle is typically about the diameter of a single eukaryotic cell, the precise location of the emitting atom in the tissue cells becomes ...
The endocrine system is a complex network of glands and organs that produce and release hormones which control many of our body’s basic functions, such as metabolism, growth and reproduction.
Though one's body produces peptides naturally, peptides are also found in many food and supplement sources. "All the food we eat is broken down by the body into amino acids," explains Stevenson.
“The biggest muscles are in your lower body—your quads and glutes, among other things,” says Albert Matheny, RD, CSCS, co-founder of SoHo Strength Lab. “The treadmill uses all of those ...
The oxygen enhancement ratio (OER) or oxygen enhancement effect in radiobiology refers to the enhancement of therapeutic or detrimental effect of ionizing radiation due to the presence of oxygen.
