The Emerging Roles of Exosomes as EMT Regulators in Cancer

open access: yesCells, 2020
Epithelial–mesenchymal transition (EMT) causes epithelial cells to lose their polarity and adhesion property, and endows them with migratory and invasive properties to enable them to become mesenchymal stem cells.

Radiation dose in vertebroplasty [PDF]

open access: yesNeuroradiology, 2004
We wished to measure the absorbed radiation dose during fluoroscopically controlled vertebroplasty and to assess the possibility of deterministic radiation effects to the operator. The dose was measured in 11 consecutive procedures using thermoluminescent ring dosimeters on the hand of the operator and electronic dosimeters inside and outside of the ...

Organ-Specific Effects of Low Dose Radiation Exposure: A Comprehensive Review

open access: yesFrontiers in Genetics, 2020
Ionizing radiation (IR) is a high-energy radiation whose biological effects depend on the irradiation doses. Low-dose radiation (LDR) is delivered during medical diagnoses or by an exposure to radioactive elements and has been linked to the occurrence of

Development of Methods to Evaluate Several Levels of Uranium Concentrations in Drainage Water Using Total Reflection X-Ray Fluorescence Technique

open access: yesFrontiers in Chemistry, 2019
As a country's law stipulates the effluent standard uranium concentration in drainage water, the uranium concentration must be determined when drainage water is released from a uranium handling facility, such as the Fukushima Daiichi nuclear power plant.

Analysis of repeated computed tomography scans and cumulative effective dose of patients in a hospital

open access: yesBrazilian Journal of Radiation Sciences, 2023
Computed tomography exams are considered diagnostic imaging exams that generate significant radiation dose to the patient. Justification, optimization, and dose limitation are radiological protection principles used to minimize patient and staff exposure,

Impact of Radiation Dose to the Host Immune System on Tumor Control and Survival for Stage III Non-Small Cell Lung Cancer Treated with Definitive Radiotherapy.

open access: yesInternational Journal of Radiation Oncology, Biology, Physics, 2019
INTRODUCTION The significance of radiation dose to the host immune system during the treatment of stage III non-small cell lung cancer (NSCLC) is unknown, but higher doses were associated with worse tumor control and overall survival in a secondary ...
