Study on Three-Dimensional Analysis Method of Radiation Dose of GEO Satellite [PDF]

open access: yesMATEC Web of Conferences, 2019
GEO satellite in orbit is greatly affected by the total radiation dose of space environment. In order to meet the requirements of satellite reliability design, radiation dose analysis is an important work in the process of satellite design.

A flexible multivariate random effects proportional odds model with application to adverse effects during radiation therapy

open access: yes, 2016
Radiation therapy in patients with head and neck cancer has a toxic effect on mucosa, the soft tissue in and around the mouth. Hence mucositis is a serious common side effect and is a condition characterized by pain and inflammation of the surface of the

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

open access: yesMolecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Evaluating bone marrow dosimetry with the addition of bone marrow structures to the medical internal radiation dose phantom

open access: yesPrecision Radiation Oncology, 2023
Background Reliable estimates of radiation dose to bone marrow are critical to understanding the risk of radiation‐induced cancers. Although the medical internal radiation dose phantom is routinely used for dose estimation, bone marrow is not defined in ...

Effects of the Shape of the Radiation Dose-Response Curve on Public Acceptance of Radiation and Nuclear Energy [PDF]

open access: yes, 2002
[Excerpt] “The public generally accepts the premise that exposure to radiation can have an undesirable effect. Furthermore, it believes that as the radiation dose increases, the magnitude of the effect will increase.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

open access: yesMolecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Historical Development of the Linear Nonthreshold Dose-Response Model as Applied to Radiation [PDF]

open access: yes, 2002
[Excerpt] Despite the nearly universal adoption of the linear nonthreshold dose response model (LNT) as the primary basis for radiation protection standards for the past half century, the LNT remains highly controversial and a contentious topic of ...
