The research focused on the damage done to DNA indirectly by oxidizing chemical species such as the hydroxyl radical
High doses of X-rays and other kinds of ionizing radiation can damage the DNA present in the cell nucleus, a phenomenon which can both lead to the development of cancer in humans and be used to kill cancer cells. This damage to DNA occurs through two mechanisms: one involves the direct physical impact of ionizing particles; the other is indirect, involving an attack on [...]

This damage to DNA occurs through two mechanisms: one involves the direct physical impact of ionizing particles; the other is indirect, involving an attack on nucleic acids by chemical species arising from water radiolysis (the decomposition of hydrogen bonds between H2O [...]

Scientists have made a major breakthrough in understanding how ionizing radiation affects our DNA. In a recent study, published in the journal Nature Communications, researchers from the University of Tokyo have elucidated the mechanism of ionizing radiation-induced DNA damage.
This breakthrough could pave the way for better treatments and therapies for cancer patients, as well as a better understanding of the long-term effects of radiation exposure.
We are excited to share the news that [...]

A radiação ionizante (como, por exemplo, os raios X) em altas doses pode danificar o DNA presente no núcleo celular – algo que pode tanto levar ao desenvolvimento de câncer em humanos como ser explorado para matar células cancerígenas. Esse dano ao DNA se dá por meio de dois mecanismos: um direto, em que a partícula ionizante impacta fisicamente a molécula, e outro indireto, em que espécies químicas produzidas [...]
