Historical Changes in Histological Diagnosis of Lung Cancer

Journal of Epidemiology, 2019
Background: Histological classification of lung cancer is essential for investigations of carcinogenesis and treatment selection. We examined the temporal changes of lung cancer histological subtypes. Methods: Lung cancer cases diagnosed in the Life Span

Chronic Inflammation and Radiation-Induced Cystitis: Molecular Background and Therapeutic Perspectives

Cells, 2020
Radiation cystitis is a potential complication following the therapeutic irradiation of pelvic cancers. Its clinical management remains unclear, and few preclinical data are available on its underlying pathophysiology.

Effects of Radiation on Hemopoiesis

Radiology, 1948
A consideration of the effects of radiation on the hemopoietic tissues brings one into a controversial field. This is necessarily so, since various modes of subjecting the blood and the hemopoietic tissues to radiation have been used. Further, results in one species do not always agree with those in other species and hence confusion is frequently ...

Dose Variations Using an X-Ray Cabinet to Establish in vitro Dose-Response Curves for Biological Dosimetry Assays

Frontiers in Public Health, 2022
In biological dosimetry, dose-response curves are essential for reliable retrospective dose estimation of individual exposure in case of a radiation accident.

Post-Irradiation Thymic Regeneration in B6C3F1 Mice Is Age Dependent and Modulated by Activation of the PI3K-AKT-mTOR Pathway

Biology, 2022
The risk of radiation-induced carcinogenesis depends on age at exposure. We previously reported principal causative genes in lymphomas arising after infant or adult exposure to 4-fractionated irradiation as Pten or Ikzf1, respectively, suggesting that ...

ΔNp63α transcriptionally represses p53 target genes involved in the radiation-induced DNA damage response

Radiation Oncology, 2022
Background The DNA damage response (DDR) is a mechanism that protects cells against radiation-induced oxidative DNA damage by causing cell cycle arrest and apoptosis. TP63 is a member of the tumour suppressor TP53 gene family, and ΔNp63α, a TP63 splicing

COVID-19-Associated Pneumonia: Radiobiological Insights

Frontiers in Pharmacology, 2021
The evolution of SARS-CoV-2 pneumonia to acute respiratory distress syndrome is linked to a virus-induced “cytokine storm”, associated with systemic inflammation, coagulopathies, endothelial damage, thrombo-inflammation, immune system deregulation and ...

Effects of Omitting Non-confounding Predictors From General Relative-Risk Models for Binary Outcomes

Journal of Epidemiology, 2019
Background: The effects, in terms of bias and precision, of omitting non-confounding predictive covariates from generalized linear models have been well studied, and it is known that such omission results in attenuation bias but increased precision with ...

Critical Review on Toxicological Mechanisms Triggered by Inhalation of Alumina Nanoparticles on to the Lungs

Biomedicines, 2022
Alumina nanoparticles (Al2O3 NPs) can be released in occupational environments in different contexts such as industry, defense, and aerospace. Workers can be exposed by inhalation to these NPs, for instance, through welding fumes or aerosolized ...
