Individual dosimetry as an element of health prevention for employees exposed to ionizing radiation

Medycyna Pracy, 2023
The paper presents the current radiation protection standards, in line with the recommendations of the International Commission on Radiological Protection (ICRP), and their evolution over the years based on new knowledge about the biological effects of ...

Bioterrorismo. Etiopatogenia da agressão por radiações

Revista Portuguesa de Pneumologia, 2004
RESUMO: Depois de se abordarem as diversas possibilidades de terrorismo nuclear e de se referirem as unidades de medida da radiação ionizante, fazemos uma descrição detalhada dos efeitos biológico da radiação. Para além de se referirem as acções directas

Radiation hormesis and adoptive response induced by low doses of limiting radiation [PDF]

Journal of Kerman University of Medical Sciences, 1997
Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems  to be induced at low doses of exposure.

Biologic effect of ionizing radiation [PDF]

Interventional Cardiology, 2018
Ionizing radiation is a well-known risk factor for developing benign and malignant diseases including different types of cancer. Despite its proven deleterious effects there is still a high unawareness about its importance. There is no a complete adherence to the use of protective tools for avoiding radiation exposure in the cath lab, especially in ...

Phosphoproteomics profiling of human skin fibroblast cells reveals pathways and proteins affected by low doses of ionizing radiation. [PDF]

PLoS ONE, 2010
High doses of ionizing radiation result in biological damage; however, the precise relationships between long-term health effects, including cancer, and low-dose exposures remain poorly understood and are currently extrapolated using high-dose exposure ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Effects of Ionizing Radiation on Flora Ten Years after the Fukushima Dai-ichi Disaster

Plants, 2022
The aim of this work is to analyze the effects of ionizing radiation and radionuclides (like 137Cs) in several higher plants located around the Fukushima Dai-ichi Nuclear Power Plant (FNPP), evaluating both their adaptive processes and evolution.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

NATURALRADIOACTIVITY IN HUMAN ENVIRONMENT

Human Research in Rehabilitation, 2011
Since the radioactivity can not be detected by senses, the most usual reaction to it is fear of unknown. The majority of non-professionals share the common concept of radioactivity as something mysterious and dangerous.

Quantitative modeling of carcinogenesis induced by single beams or mixtures of space radiations using targeted and non-targeted effects

Scientific Reports, 2021
Ionizing radiations encountered by astronauts on deep space missions produce biological damage by two main mechanisms: (1) Targeted effects (TE) due to direct traversals of cells by ionizing tracks.
