Summary: The wound healing process involves communication between different cellular factors, and the radio frequency electromagnetic field (RF-EMF) has been used to accelerate this process. A novel electromagnetic exposure system integrated with a microfluidic chip was developed to study the cellular response to exposure. The system achieved precise and high-throughput detection of the RF-EMF-induced cytoskeletal reorganization in vitro.

Summary: Recent studies have examined the impact of low-intensity radiofrequency (RF) fields on thermoregulation and adipose tissue metabolism. This study investigates the expression of thermoregulatory genes and the involvement of mitochondria in adipose tissue metabolism. The findings suggest that RF exposure leads to changes in adipose tissue markers, with some effects depending on the dose and duration of exposure.

Summary: This study aimed to investigate the correlation between mobile phone radiation and human health, including cognitive performance, health-related quality of life, and sleep. The results showed that there were sporadic associations between wireless phone use and screen time with cognitive performance, but no significant associations with HRQoL or sleep duration and quality. Increased screen time was found to be associated with increased stress, but there was no association with phone call time or sleep.

Summary: Ticks have been shown to regulate their body temperature by eliminating fluid (urine) through their coxal glands, which spreads over the cuticular surface and cools down their body. This thermoregulatory mechanism is made possible by capillary diffusion through the sculptured exoskeleton of Ornithodoros.

Summary: The controversy surrounding electrohypersensitivity (EHS) is due to the lack of recognized criteria for diagnosis. However, there is enough data to consider EHS as a well-defined neurologic disorder. EHS and multiple chemical sensitivity (MCS) share a common pathophysiological mechanism, making them a unique neurologic syndrome. EHS is caused by exposure to electromagnetic fields (EMFs), which induce objective pathophysiological changes and health effects.

Summary: There is evidence indicating that environmental factors can lead to changes in DNA methylation (DNAm). Radiofrequency electromagnetic fields (RF-EMFs), emitted by everyday devices, have been classified as potentially carcinogenic, but their biological effects are not clear. This study aimed to determine the effect of RF-EMF exposure on DNAm of different classes of repetitive elements (REs). The results showed that RF exposure did not affect the DNAm of Alu elements, but influenced the DNAm of LINE-1 and ribosomal repeats in different ways in each cell line studied.

Summary: This study demonstrates that exposure to a specific radio-frequency electromagnetic field can enhance the production of the enzyme alpha-amylase in a filamentous fungus, leading to increased protein concentration and activity. The exposure also affects the intracellular calcium level and transcription of genes involved in protein cellular trafficking.

Summary: The utilization of digital technology has led to an increase in cell phone use, resulting in electromagnetic radiation that has adverse effects on the brain, making it a new source of pollution. This study investigated the effects of lipoic acid on cognitive functions and hippocampal structure in rats exposed to electromagnetic fields emitted from multiple cell phones. The results showed that EMF exposure enhanced learning ability but interfered with long-term memory consolidation, and lipoic acid treatment improved both learning and memory.

Summary: Due to the evolution of temporal shortening of the current pulses, new developments on Rogowski coil have been presented for the study of biophysical stresses by electromagnetic pulses and applied for electrical current diagnostics. The use of an electrostatic shield with a slim slit protects the Rogowski coil and influences its response to high frequency signals.

Summary: Recent studies have shown that rodents exposed to low-intensity radiofrequency (RF) exhibit vasoconstriction responses similar to those in cold conditions, suggesting that RF exposure triggers physiological events associated with responses to cold in rats. RF exposure also leads to increased plasma concentrations of noradrenaline and fatty acids, similar to the response to cold stimuli.

Summary: This study developed a pregnancy physiologically based pharmacokinetic model to characterize fetal permethrin exposure in rats, highlighting the distribution and transfer of permethrin in maternal and fetal tissues, especially in the fetal brain. This work could be applied to estimate prenatal exposure and placental transfer of permethrin in humans using biomonitoring data.

Summary: This study compared measurements of radiofrequency electromagnetic field (RF-EMF) exposure obtained from different personal exposimeters and a multi-band body-worn distributed exposimeter (BWDM) in real-life conditions. Results showed that exposimeters worn on-body provided slightly lower total RF-EMF exposure compared to BWDM measurements, likely due to the effects of body shielding. There was high correspondence in the ranking of exposure levels in microenvironments between different device types.

Summary: The ability to induce hypothermia resembling natural torpor has significant benefits. Two pharmacological procedures based on central nervous manipulation have proven effective in lowering body temperature in non-hibernating rats. The role of mitochondria in centrally induced hypothermia in non-hibernators is still not well understood.

Summary: Counting cells in fluorescent microscopy is a tedious task that can be improved using deep learning methods, such as the proposed c-ResUnet model. Through ablation studies, the impact of design choices like artifacts oversampling and weight maps are evaluated and found to enhance overall performance. The release of the pre-trained model and annotated dataset aims to foster research in this field and related areas.

Summary: Recent research has discovered that the preoptic area of the hypothalamus and the dorsomedial hypothalamus (DMH) are involved in the regulation of daily torpor in mice. Using activity-dependent genetic techniques, scientists were able to target and manipulate DMH neurons to promote or inhibit torpor. This study further supports the role of these neurons in controlling torpor.

Summary: A short-term sleep deprivation soon after regaining euthermia can enhance the reversibility of Tau protein hyperphosphorylation induced by torpor, possibly due to higher body temperature, melatonin levels, and resting phenotype of microglia. This finding suggests that sleep deprivation may boost a latent neuroprotective mechanism.

Summary: Rats emit a distress call of 22-kHz ultrasonic vocalisation to warn their group of danger. Surprisingly, this study found that rats can emit these vocalisations during REM sleep, but not during non-REM sleep. The emission occurs during the expiratory phase and can happen singularly or as a train. This is the first report to demonstrate rats vocalising during REM sleep.
