This study examined the impact of RF-EMF (900-1900 MHz) on symptoms spanning four health categories: mood-energy, cognitive-sensory, inflammatory, and anatomical issues. A questionnaire identifying health symptoms within these categories, was given to 183 highly exposed and 126 reference residents, matched on demographics. While years of residing near the MPBS influenced the prevalence of some symptoms, proximity to the base station and higher levels of exposure (measured using power density) influenced the prevalence of many of the symptoms. A higher proportion of symptoms was found in residents who were either living within 50 meters of a MPBS or who were exposed to power densities of 5-8 mW/m², for all four health categories. This relationship between exposure level and symptom prevalence was further influenced by age, daily mobile phone use (over 5 h per day), and lifestyle factors, for certain symptoms. Hierarchical regression analysis revealed that level of exposure (power density) was the only factor contributing to the number of symptoms experienced by residents, for all four health categories. An unexpected finding was that among the more highly exposed residents, the younger individuals (under 40 years) reported more inflammation related issues than older individuals. These results underscore the need to inform policymakers regarding the benefits of adopting a precautionary approach to potential risks associated with RF-EMF exposures from MPBS.</p>","PeriodicalId":50544,"journal":{"name":"Electromagnetic Biology and Medicine","volume":" ","pages":"1-20"},"PeriodicalIF":1.6,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144250648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research has demonstrated that NEMP can disrupt the male reproductive system. Molecular hydrogen, a selective hydroxyl radical scavenger, has been shown to have the protective effects against many diseases closely associated with oxidative damage. We sought to characterize the beneficial effects of molecular hydrogen on the male reproductive cells. GC-1 spermatogonial cells and TM-3 Leydig cells, two well-established male reproductive cell lines, were exposed to NEMP. Finally, we employed transcriptomic sequencing to explore the transcriptional changes in male reproductive cells induced by NEMP exposure. For the intervention, cells were incubated in hydrogen gas (H₂ 75%, O₂ 20%, and CO₂ 5%) for 1 h. NEMP exposure induced damage to both GC-1 and TM-3 cells, resulting in decreased cell viability and increased apoptosis rates. However, intervention with molecular hydrogen significantly mitigated this damage. Specifically, molecular hydrogen reduced the production of ROS and restored mitochondrial function, thereby alleviating oxidative stress and apoptosis. Transcriptomic sequencing analysis showed that NEMP affected the molecular function term antioxidant activity, particularly Gstp2, a gene predicted to be located in the mitochondria to promote glutathione transferase activity.

Cells and proteins may have evolved to take advantage of frequencies naturally present in the Earth's EMF, potentially enhancing cellular energy levels and affecting resting membrane potential (RMP). Thus, changes in or absence of SR may have adverse effects on the functioning of the whole organism. Bioelectricity, independent of genes, has been shown to modulate health, suggesting the potential for using controlled application of EMF frequencies in treating certain types of cancer or conditions affecting the RMP. Research indicates that human brainwave activity is highly dependent on the SR, implying a correlation between atmospheric electromagnetic frequencies and brain activity. ELF, including SR, appears to modulate cellular calcium influx/efflux, likely via indirect mechanisms involving field-sensitive molecules or radical pairs that affect ion channel behavior which plays a critical role in cell signaling and regulation of various processes. It can also trigger a cascade of molecular events that ultimately lead to the generation of action potentials, affecting consciousness and behavior. The influence of atmospheric electromagnetic frequencies on human brainwave activity, modulation of cellular calcium influx/efflux, and potential effects on cellular energy levels and RMP highlight the significance of ELF in biological systems.

This research focuses on predicting the flow patterns of blood infused with gold and maghemite nanoparticles (gold-maghemite/blood) inside an EM microchannel under these electromagnetic influences and abruptly change in pressure gradient. The study models these flows by considering radiation heat emission and Darcy drag forces within porous media. Mathematical representation involves time-variant partial differential equations, resolved through Laplace transform (LT) to yield compact-form expressions for the model variables. The outcomes, including shear stress (SS) and rate of heat transfer (RHT) across the microchannel, are analyzed and displayed graphically, highlighting the effects of modified Hartmann number and electrode width on these parameters. Hybrid nano-blood (HNB) and nano-blood (NB) exhibit distinct thermal characteristics, with HNB transferring more heat within the blood flow. These study implements a cutting-edge AI-powered approach for high-fidelity evaluation of critical flow parameters, achieving unprecedented prediction accuracy. Validation results confirm the algorithm's excellence, with SS predictions reaching 99.552% (testing) and 97.019% (cross-validation) accuracy, while RHT predictions show 100% testing accuracy and 97.987% cross-validation reliability. This convergence of nanotechnology with advanced machine learning paves the way for transformative clinical applications that could redefine standards of care in surgical oncology, interventional cardiology, and therapeutic radiology.

Therefore, our study focuses on exploring the impact of 5 G signal exposure on human fatigue, particularly considering the influence of expectancy induced by psychological priming on the outcomes. In this study, we recruited 21 healthy subjects who were tested in three sessions. Each session included two 30-min exposures to either real or sham 5 G signals, with the order randomized.

The statistical comparison indicates that 5 G RF-EMF exposure at routine levels does not lead to changes in EEG power. The finding reveals that the report of fatigue can be altered by the conveyed information of being exposed by 5 G signals although there is no real exposure and no detectable electrophysiological indicator.
