Radiosensitivity is the relative susceptibility of cells, tissues, organs or organisms to the harmful effect of ionizing radiation. Cells types affected [ edit ]
Conventional chemotherapeutics are currently being used in conjunction with radiation therapy to increase its effectiveness. Examples include the fluoropyrimidines, gemcitabine and platinum analogs; fluoropyrimidines increase sensitivity by dysregulating S-phase cell cycle checkpoints in tumor cells.
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 ...
The "Turkish get-up" (TGU) is an ideal exercise to put your strength and mobility to the test. This total-body workout requires you to move from lying down on the floor to a standing position ...
When it comes to muscular diseases, most of us have heard of especially common ones like muscular dystrophy and Lou Gehrig's disease.But one of the rarest muscular disorders is also one of the ...
Early detection is widely seen as key to cancer survival, which is why screenings and prevention are so widely recommended. And the message seems to be getting across, according to a study led by ...
It is important to distinguish the radiosensitivity of a particular tumor, which to some extent is a laboratory measure, from the radiation "curability" of a cancer in actual clinical practice. For example, leukemias are not generally curable with radiation therapy, because they are disseminated through the body.
As you grow into your 40s and beyond, your body starts to lose lean muscle mass if you don't perform strength training. Therefore, if you're trying to get into shape and stay in shape, strength ...
