Purpose: To evaluate the knowledge of physicians prescribing CT examinations on the radiation protection of patients.
Materials And Methods: A questionnaire was distributed to all clinicians on medical staff who prescribe CT examinations. Several questions related to their prescription pattern and their knowledge of radiation protection.
Results: Forty-four questionnaires were analyzed. While 70% of physicians claimed that they considered the risks from exposure to ionizing radiation when prescribing a CT examination, only 25% informed their patients about those risks. Knowledge of the radiation dose delivered during CT evaluation of the abdomen and pelvis was poorly understood and the risks related to small doses of radiation were grossly underestimated. Finally, only a third of clinicians had received training with regards to radiation protection.
Conclusion: While most clinicians claim that they consider the risks from exposure to ionizing radiation when prescribing a CT examination, the risks are either not well known or not known at all. Increased formation of clinicians with regards to the radiation protection of patients, maybe through a dedicated clinical rotation while in medical school, could be a solution to improve the knowledge of hospital clinicians with regards to radiation protection.

Unlabelled: Melanin pigments block genotoxic agents by positioning on the sun-exposed side of human skin keratinocytes' nucleus. How this position is regulated and its role in genome photoprotection remains unknown. By developing a model of human keratinocytes internalizing extracellular melanin into pigment organelles, we show that keratin 5/14 intermediate filaments mechanically control the 3D perinuclear position of pigments, shielding DNA from photodamage.

Detection of biomolecules, Glutathione (GSH) in particular, is important because it helps assess antioxidant capacity, cellular protection, detoxification processes, and potential disease associations. Monitoring glutathione levels can provide valuable information about overall health and well-being. Many medical disorders have been connected to glutathione levels.

Vegetation productivity and ecosystem carbon sink capacity are significantly influenced by seasonal weather patterns. The time lags between changes in these patterns and ecosystem (including vegetation) responses is a critical aspect in vegetation-climate and ecosystem-climate interactions. These lags can vary considerably due to the spatial heterogeneity of vegetation and ecosystems.

The slope aspect is an important environmental factor, which can indirectly change the acceptable solar radiation of forests. However, the mechanism of how this aspect changes the underground ecosystem and thus affects the growth of aboveground trees is not clear. In this study, Pinus yunnanensis plantation was taken as the research object, and the effects of soil and microbial characteristics on tree growth under different slope aspects and soil depths were systematically analyzed.
