“…ABC controls the light output of the image receptor by adjusting the kVp and/or mA of the x-ray tube using a preprogrammed kVp-mA curve. 40 The small size and design of the MOSkin detector do not change the ABC exposure parameters when it is in the beam. In this study, the MOSkin detector was set up, per the standard setup, and the sensitivity of the MOSkin detector was studied for the dose range of 2 to 213 cGy.…”

“…Finally, it is important to note that plant cells have a very high water content and previous authors have shown that the action of ionizing radiation on water is to generate reactive free radicals (Dendy & Heaton, 1999; Allison, 2006). Exposed to an ESEM beam, the dominant reactive species in water has been shown to be small, highly mobile hydroxyl radicals and the relatively stable hydrogen peroxide (Royall et al , 2001) both of which would be expected to degrade the specimen.…”

Summary Historically, electron microscopy of dynamic biological processes has been impossible to achieve in real time because conventional electron microscopy requires specimen fixation, dehydration and metallic coating. The advent of the environmental scanning electron microscope removes these restrictions, allowing fully hydrated samples to be imaged in their native state. We explore the possibility of secondary electron imaging of biological systems undergoing natural morphological changes in the microscope chamber and present a proof of principle study on the closure of stomatal pores in Tradescantia andersonia leaf tissue. An imaging protocol is developed and the advantages and limitations of this high‐resolution imaging technique are considered, including a discussion of potential beam damage mechanisms.

“…X-rays are in most aspects similar to γ-rays but differ in origin. While γ-rays are derived from the natural decay of radioactive elements, X-rays are artificially produced in X-ray generators by directing a stream of high-speed electrons at a target material, such as gold or tungsten [14]. When electrons interact with atomic particles of the target, X-radiation is produced [12].…”

Endothelial Dysfunction - Old Concepts and New Challenges

Along with the development of novel chemotherapeutic agents, radiation therapy has revolutionized the prognosis of patients with various cancers. However, with a longer life expectancy, radiation treatment-related comorbidity, like cardiovascular diseases (CVDs), becomes an issue for cancer survivors. In addition, exposure to X-rays for medical diagnostics is dramatically increasing at the present times. A pressing question is whether or not exposure to these very low doses can cause health damage. Below 0.5 gray (Gy), an increased risk cannot be evidenced by epidemiology alone, and in vitro and in vivo mechanistic studies focused on the elucidation of molecular signaling pathways are needed. Given the critical role of the endothelium in normal vascular functions, a complete understanding of radiation-induced endothelial dysfunction is crucial. In this way, the current radiation protection system could be refined if needed, making it possible to more accurately assess the cardiovascular risk in the low-dose region. Finally, radiation-induced CVD, like CVD in general, is a progressive disorder that may take years to decades to manifest. Therefore, experimental studies are warranted to fulfill the urgent need to identify noninvasive biomarkers for an early detection and potential interventions-together with a healthy lifestyle-that may prevent or mitigate these adverse effects.
