122. Towards the characterization of single-cell molecular response to ionizing radiation

Pierre Beaudier (CNRS)

ORAL

The focus of the studies of ionizing radiation damage has historically been centered on the direct impact on DNA due to the important mutagenic effects, especially at higher doses. This outlook tends to minimize the potential for cellular damage on other macro-molecules responsible for cellular functions such as RNA which share a highly similar structure with DNA and can thus be considered at...

115. Maternal and paternal exposure to low dose radiation and adverse birth outcomes: preliminary findings from a systematic review and meta-analysis

Brianna Frangione (Department of Health Sciences, Carleton University)

ORAL

Exposure to ionizing radiation is recognized to increase the risk of cancer and cardiovascular disease, while the impacts on adverse birth outcomes are less understood. We undertook a systematic review and a meta-analysis to summarize the epidemiological literature of maternal and paternal exposure to radiation (<5 Gy) and birth outcomes including preterm birth, miscarriage, and low...

143. Low dose rate radiation exposure effects among medical workers from the knowledge of epidemiologic studies.

Dr Maroua IDLIL (Sultan Moulay Slimane University)

ORAL

In medicine ionizing radiation is used for therapeutic and diagnostic purposes, it inevitably leads to inadvertent exposure of medical workers to a certain level, especially in the earlier years when equipment was less sophisticated and radiation protection was not stringent so the dose received by the medical staff has been greater.
Many people are or have been exposed to ionizing radiation...

120. Ionising radiation exposure of Medical staff: risks and prevention

Cyrine EL HASSANE (Faculté de médecine, Algiers, Algeria)

ORAL

Nowadays, the use of ionising radiations in medical exams is unavoidable: whether for radiology diagnostic or radiotherapy. The use of such radiations is in most cases necessary or benefit for patients but the risks to health for medical staff are not always neglected.
In this study, we review the results of some studies in term of radiation doses received by hospital staff in different...

132. Radiolysis of concentrated myoglobin by accelerated ions

Dr Quentin Raffy (IPHC / Radiochimie)

30/06/2022 10:00

ORAL

In order to better describe the biological effects of ionizing radiation, understanding the mechanisms of radiolysis at the molecular scale is a key step. Proteins are by far the most abundant biomolecules in the cell, yet very few studies describe their radiolysis by accelerated ions. The aim of our team is therefore to develop a systematic study of these effects on protein biomolecules, from...

133. Effects of the dose-rate on the radiolysis of water and small protein biomolecules

Antoine DANVIN (IPHC / Radiochimie)

ORAL

Ionizing radiations are known to have important effects on living organisms, as their energy deposition causes a lot of damages. Studying fundamental chemical mechanisms of the effects of ionizing radiations on biomolecules is crucial to have a better understanding of their radiobiological effects. These ionizing radiations can come from radioactive isotopes, or be used in a therapeutical...
