In this study, which is the second phase of our previous study, the thyroids of rats exposed to prenatal 2.45 GHz RFR were examined one year after birth. The mothers of the offspring in the experimental group (n = 8) were exposed to 2.45 GHz RFR (whole-body specific absorption rate (SAR): 12 mW/kg; maximum point SAR: 25 mW/kg) 24 hours per day throughout pregnancy. The mothers in the sham group (n = 8) were kept under the same experimental conditions except for RFR exposure. The offspring in this study were not exposed to RFR after birth and continued their daily lives for one year. When the offspring reached one year of age, they were sacrificed and their thyroids were removed and evaluated. Mann-Whitney U and t tests were used for statistical analysis. Increases in fibrosis (p = 0.038), atypical thyrocytes (p = 0.002) and degenerated follicles (p = 0.007) and colloid reduction (p = 0.002) were found to be significant in the experimental group compared to the sham group. However, the increase in the percentage of apoptosis positive cells (p = 0.006) and H2A.X antibody levels (p = 0.007) showed a statistically significant difference in the experimental group compared to the sham group. This study provides evidence that prenatal exposure to 2.45 GHz RFR can induce persistent histological changes, increase apoptosis, and cause DNA double-strand breaks in thyroid tissue observed one year after birth. These results underscore the importance of further long-term studies to assess developmental risks associated with prenatal RFR exposure.","PeriodicalId":50544,"journal":{"name":"Electromagnetic Biology and Medicine","volume":" ","pages":"1-10"},"PeriodicalIF":1.5,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145349910","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}

However, only a few examples of distinct biological effects have been reported due to the lack of strong THz radiation sources. Here, we report our preliminary investigation using a strong THz source at 1.56 THz with an average power of ~ 10 W and an average intensity of ~129.1 mW/cm2 working at a repetition rate of 10 Hz for its macro pulses with duration of ~1 ms and micro pulse duration of ~ 1 ps at a repetition rate of 54.17 MHz from a THz free-electron laser to investigate its biological effects on breast cancer cells in vitro. We observed significant morphological changes in breast cancer cells after 2 hours irradiation and apoptosis after 3 hours irradiation. Most notably, after 4 hours irradiation, we observed obvious cytolysis and the disappearance of most breast cancer cells in the center of the THz beam spot. It is suggested that these biological effects could be attributed mainly to the non-thermal effect of the strong THz waves according to our separate experimental results on the morphological changes of the breast cancer cells induced solely by heat. Our results indicate the potential to leverage the apoptosis and cytolysis of cancer cells induced by strong THz waves for future cancer treatment applications.","PeriodicalId":50544,"journal":{"name":"Electromagnetic Biology and Medicine","volume":" ","pages":"1-11"},"PeriodicalIF":1.5,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145337920","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}

This study aims to elucidate the fundamental principles and plausible mechanisms by which EMFs may influence physiological and pathological processes that lead to disease development.Materials and methods: Published reports of oxidative stress, DNA damage, and disease risk related to EMF exposure were examined. The literature review provided the foundation for building a new conceptual model called the Electromagnetic Pathogenesis (EMP) model.Mechanisms: The EMP model proposes an increase in the probability of electron tunneling through the mitochondrial electron transport chain as the primary pathophysiological mechanism triggered by non-ionizing EMFs. Induced electric fields and quantum tunneling may enhance electron leakage during mitochondrial respiration, which is a major source of free radicals.Findings: There is a deep connection between quantum tunneling, entropy, and Heisenberg's principle. As a direct consequence of Heisenberg's principle, еlectron tunneling is essentially involved in free radical production and entropy generation in cells. Both normal aging and chronic diseases may be considered as the biologic manifestations of increasing entropy. Heisenberg's principle underlies normal aging and sets the limit to life expectancy.Social implications: The human brain, particularly the structural and functional networks that support social communication, is highly vulnerable to oxidative stress associated with EMF exposure. Long-term exposure may negatively affect social and reproductive behaviors in both men and women, potentially contributing to a decline in fertility rates and the acceleration of population aging.","PeriodicalId":50544,"journal":{"name":"Electromagnetic Biology and Medicine","volume":" ","pages":"1-25"},"PeriodicalIF":1.5,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338047","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}

The exposure groups were exposed to EMR from an activated 1800 MHz and Specific Absorption Rate (SAR) = 0.897 W/Kg mobile phone for 2 hours/day for 30 days.

However, owing to the complicated configuration of DTMS coils, such as the H1 coil, the electric field induced by it in the personalized human brain is so varied and complex that its transcranial magnetic stimulation performances, especially focusing behavior and depth characteristics, have to be studied and evaluated further before clinical application. Therefore, besides the effects of the excitation frequency of the H1 coils, two types of magnetic shielding blocks (MSBs) with various dimensions were analyzed, and the H1 coil circuit structure with flexible length adjustment and its coil spacing were also investigated in this study. Finally, a machine learning model based on an optimizable tree algorithm was established to rapidly predict the induced electric field in the personalized human brain. Results demonstrated that the half-value depth D1/2 of the electric field induced by the H1 coil could reach 3.67 cm, which was deeper than that by the figure-of-eight (FOE) coil (<1.6 cm), but its focusing (half-value) volume V1/2 was 567.94 cm3, larger than that of the FOE coil. After introducing MSBs, reasonably adjusting the coil circuit length and the coil spacing, V1/2 was reduced to 81.748 cm3, with a slight increase in D1/2. The proposed machine learning model exhibited a good prediction performance (R2 = 0.99, etc.) and only took about 0.014 s to finish predicting the induced electric field in the personalized human brain for rapidly evaluating the H1 coil performance in clinical practices.","PeriodicalId":50544,"journal":{"name":"Electromagnetic Biology and Medicine","volume":" ","pages":"1-26"},"PeriodicalIF":1.5,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145126394","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}
