Tsallis entropy approach to radiotherapy treatments

, 2013
The biological effect of one single radiation dose on a living tissue has been described by several radiobiological models. However, the fractionated radiotherapy requires to account for a new magnitude: time.

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

Advanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Comparison of Radiation-Induced Bystander Effect in QU-DB Cells after Acute and Fractionated Irradiation: An In Vitro Study

Cell Journal, 2016
Objective: Radiation effects induced in non-irradiated cells are termed radiation-induced bystander effects (RIBE). The present study intends to examine the RIBE response of QU-DB bystander cells to first, second and third radiation fractions and ...

Origin-Destination Demand Prediction: An Urban Radiation and Attraction Perspective [PDF]

arXiv
In recent years, origin-destination (OD) demand prediction has gained significant attention for its profound implications in urban development. Existing data-driven deep learning methods primarily focus on the spatial or temporal dependency between regions yet neglecting regions' fundamental functional difference.

Factors modifying the response of large animals to low-intensity radiation exposure [PDF]

, 1972
In assessing the biological response to space radiation, two of the most important modifying factors are dose protraction and dose distribution to the body.

Synthetic Bilirubin‐Based Nanomedicine Protects Against Renal Ischemia/Reperfusion Injury Through Antioxidant and Immune‐Modulating Activity

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
BX‐001N, a polyethylene glycol‐conjugated bilirubin 3α nanoparticle, is the first GMP‐grade, synthetic bilirubin‐based nanomedicine. It effectively attenuates acute renal injury, facilitates subacute renal recovery, and suppresses chronic fibrosis after renal ischemia/reperfusion injury via anti‐oxidant and immune‐modulating activity.

Computational Modeling of Signaling Pathways Mediating Cell Cycle Checkpoint Control and Apoptotic Responses to Ionizing Radiation-Induced DNA Damage

Dose-Response, 2012
The shape of dose response of ionizing radiation (IR) induced cancer at low dose region, either linear non-threshold or J-shaped, has been a debate for a long time.

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

, 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 ...
