Summary: The generation of temperature gradients on nanoparticles heated externally by a magnetic field is crucial in magnetic hyperthermia therapy. However, the low heating power of magnetic nanoparticles limits the technique's implementation. This paper reports the real-time measurement of local temperature on gamma-Fe2O3 magnetic nanoheaters, showing that even within health safety limits, local temperature increments are sufficient to cause cell death, demonstrating the feasibility of local hyperthermia.

Summary: The generation of temperature gradients on nanoparticles by an external magnetic field is crucial in magnetic hyperthermia therapy. However, the low heating power of magnetic nanoparticles at human-allowed conditions limits the technique's implementation. Local intracellular hyperthermia holds promise as an alternative, as it achieves cell death with small amounts of heat at thermosensitive intracellular sites. Reliable intracellular temperature measurements are needed to resolve the discrepancy between experimental and theoretical predictions.

Summary: This study identified risk factors associated with the occurrence of exertional heat illness (EHI) in racehorses, including race distance, wet bulb globe temperature, preceding 5-day temperature average, occurrence of a previous EHI incident, going, year, and race off time. The results provide important evidence for the industry to implement measures such as providing appropriate cool down facilities, early intervention for horses with repeated EHI incidents, and collecting new data streams like on-course wet bulb globe temperature measurements.

Summary: Heat flux systems are commonly used to assess core body temperature, but there is a lack of validation for multiple systems. In this experiment, three commercially available heat flux systems were compared to rectal temperature. The results showed that Medisim's values were lower than rectal temperature, while 3M and Core did not differ much. Therefore, caution should be taken in interpreting heat flux sensor values as core body temperature estimates, and further research is needed to explain the physiological significance of the generated temperature values.

Summary: This study demonstrates a transient microscopic method to measure heat transfer in single cells, revealing wide heterogeneity in thermal conductivity among different regions within a cell. The heat transfer near the cell membrane is more active than in the central region, while the median values of thermal conductivity across different individual cells are quite close. Furthermore, warm-blooded organisms like humans and chickens exhibit cellular-level heat regulation in response to environmental temperature, whereas cold-blooded organisms like bullfrogs do not.

Summary: Assembled magnetite nanoparticles with oriented attachment were prepared to study the effect of autoassembling on their heating efficiency. Their magnetic properties were compared with those single-core particles and it was found that both particle size and interparticle interactions determine the magnetic behavior. The samples with high superparamagnetic moment and large anisotropy barriers showed the largest specific absorption rate (SAR), indicating the importance of superparamagnetic behavior and magnetic hardness for heat generation.

Summary: This study investigates whether jerk cost (JC) can differentiate between swimming levels. The results show that elite swimmers have faster lap times and lower levels of JC compared to non-elite swimmers. Additionally, higher speed swimming is associated with more accelerations and decelerations, resulting in higher JC and lower smoothness. Overall, JC provides a simple and useful index for swimming technique.

Summary: Process operators play a crucial role in monitoring the petrochemical industry. They are often the first responders and take measures to mitigate the effects of process disruptions and incidents. Personal protective equipment is necessary as operators may be exposed to dangerous circumstances, such as high heat radiation levels during fires. This study investigated the protective clothing of operators by exposing professional firefighters to different heat radiation levels. The experiments showed that operators can be safely exposed to certain levels of heat radiation for a specific time period.

Summary: Scientific interest in pacing, as a feature of athletic competition and a window into understanding fatigue, has spanned more than 100 years. Pacing represents the pattern of energy use designed to produce a competitive result while managing fatigue of different origins. Various models, such as the teleoanticipation model and the central governor model, have been used to explain pacing. Early studies focused on managing homeostatic disturbance, while more recent studies have focused on understanding the role of psychophysiology in pacing and explaining performance decline.
