Purpose: This study aimed to assess the impact of tissue oxygen levels on transient oxygen consumption induced by ultra-high dose rate (UHDR) electron radiation in murine flank and to examine the effect of dose rate variations on this relationship.
Methods And Materials: Real-time oximetry using the phosphorescence quenching method and Oxyphor PdG4 molecular probe was employed. Continuous measurements were taken during radiation delivery on a UHDR-capable Mobetron linear accelerator.
Objectives: Telephone instructions are commonly used to improve cardiopulmonary resuscitation (CPR) by lay bystanders. This usually implies an audio but no visual connection between the provider and the emergency medical telecommunicator. We aimed to investigate whether video-guided feedback via a camera drone enhances the quality of CPR.

Article Synopsis
- Rescuers experience significant physical and psychological stress during CPR, especially in high-altitude environments where oxygen levels are lower, potentially impacting their performance.
- A study with 20 experienced mountaineers showed that heart rates during CPR were generally higher at high altitude (3454 m) compared to baseline, indicating greater physical strain.
- The findings suggest that while both scenarios result in exhaustion, the body may adapt by exhibiting a physiological reserve to cope with increased exertion in high-altitude situations.
Article Synopsis
- - Following a major radiation event, doctors will need to prioritize treatment based on how much radiation people have been exposed to, targeting care only to those who will benefit from it.
- - The text discusses a two-tier triage system: the first tier removes those unlikely to benefit, while the second tier uses biodosimetry to assess radiation doses and distribution among the remaining patients.
- - It highlights in vivo electron paramagnetic resonance nail biodosimetry as a method for quickly determining exposure levels, suggesting improvements to this technique to enhance precision and usability in real-life triage situations.
