Assessment of external occupational exposure of radiation workers in Jiangsu Province, 2019-2022.

This article analyzes the external occupational radiation exposure distribution and trends among radiation workers in Jiangsu Province. The results show that the total annual collective effective dose for radiation workers in Jiangsu Province from 2019 to 2022 was 24.82 person·Sv, with an average annual effective dose of 0.

Radiosensitivity enhancement of FeO@Ag nanoparticles on human glioblastoma cells.

Radiotherapy is one of the main therapeutic methods for cancers, but radiation resistance of cancer cells still remains a serious concern. Searching for radiosensitizers to overcome such resistance is therefore urgently required. The goal of this study is to evaluate and compare the radiosensitizing efficacy of FeO-OA, Ag and FeO@Ag nanoparticles on U251 cells.

Gamma Radiation-Induced Damage in the Zinc Finger of the Transcription Factor IIIA.

A zinc finger motif is an element of proteins that can specifically recognize and bind to DNA. Because they contain multiple cysteine residues, zinc finger motifs possess redox properties. Ionizing radiation generates a variety of free radicals in organisms.

Methemoglobin-Based Biological Dose Assessment for Human Blood.

Methemoglobin is an oxidative form of hemoglobin in erythrocytes. The authors' aim was to develop a new biological dosimeter based on a methemoglobin assay. Methemoglobin in peripheral blood (of females or males) that was exposed to a Co source (0.
