A torus source and its application for non-primary radiation evaluation.

. Non-primary radiation doses to normal tissues from proton therapy may be associated with an increased risk of secondary malignancies, particularly in long-term survivors. Thus, a systematic method to evaluate if the dose level of non-primary radiation meets the IEC standard requirements is needed.

4-in-1 FeO/g-CN@PPy-DOX nanocomposites: Magnetic targeting guided trimode combinatorial chemotherapy/PDT/PTT for cancer.

At present, cancer has become a major disease threatening human health worldwide. Therefore, developing targeting guided multimode synergetic therapy has become one of the hot spots in current antitumor research and is also a great challenge. Herein, a new FeO/g-CN@PPy-DOX nanocomposite containing magnetic iron oxide (FeO) nanoparticles (NPs), lamellar structure of graphite-like carbon nitride (g-CN) and polypyrrole (PPy) shell with the loaded anti-tumor drug doxorubicin hydrochloride (DOX) was designed and prepared.
