Radiosensitivity is the relative susceptibility of cells, tissues, ... Among the somatic effects, secondary cancer is the most important.
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.
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 ...
This is why brain tumors are far more common in elderly adults than younger ones and why people with immune system disorders are also most susceptable to developing brain tumors. ... Keeping one's ...
Researchers are uncovering deeper insights into how the human brain ages and what factors may be tied to healthier cognitive aging, including exercising, avoiding tobacco, speaking a second ...
These nuclei interact with almost every pertinent portion of the brain, but only a few of them have specifically independent interaction. These select nuclei are discussed as follows. Overall, the caudal raphe nuclei, including the nucleus raphe magnus, nucleus raphe pallidus and nucleus raphe obscurus, all project towards the spinal cord and ...
Skipping breakfast might also have some long-term negative consequences on brain health, according to a study released on November 30, 2024, in the Journal of Neurorestoratology. Let’s take a ...
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.
