“…In the study, it was reported that phones were used more than computers (15). In order to develop a planned health policy, attention should be paid to the prolonged exposure of students to mobile microwaves during e-learning during the pandemic period (16). In the study conducted in Nepal; medical students stated that they did not find online courses as effective as traditional classroom teachings (17).…”

Aim: Coronavirus disease continues to affect the whole world for nearly 3 years. In this process, the health and education community is also adversely affected. The aim of this study is to investigate the health effects of radiofrequency electromagnetic field generating devices used by medical students in distance education during the Covid-19 pandemic process.Material and Methods: Our study was conducted on medical students following distance medicine education. On 25-30 March 2020, data were collected with 22 questions and an online questionnaire (Google Form) that lasted 2 minutes. The demographic characteristics of the students, their behavior of using smartphone/ computer, age, gender, and class characteristics were investigated. Results:The mean age of medical students was 19.22±1.46 and 234 (52%) students participated. Cell phone and computer use for six hours or more was found to be over 50%. The rate of head and neck exercise after computer and smartphone use was n:28, 12%. According to the age and gender of the groups; A significant difference was found between the questions of carpal tunnel, cervical lordosis syndrome, and do you take protection from electromagnetic field (p<0.05). Conclusion:In the course of the Covid-19 pandemic, long-term exposure of students to electromagnetic fields in distance education can create important health problems.

“…The communication equipment represented by the 5G network and the radar widely used in the military field uses S- and X-band microwaves. Previous studies have shown that while microwave technology brings great convenience to social development, long-term exposure to large doses of electromagnetic radiation will cause damage to multiple organ systems of organisms to varying degrees [ 5 , 6 ]. However, there is a lack of relevant studies on the biological effects and damage mechanisms of S- and X-band microwave radiation, and pioneering studies on the heart are rare.…”

The heart is one of the major organs affected by microwave radiation, and these effects have been extensively studied. Previous studies have shown that microwave-radiation-induced heart injury might be related to the abnormal expression and distribution of Cx43. In order to make the research model closer to humans, we used iPSC-CMs as the cell injury model to investigate the biological effect and mechanism of iPSC-CM injury after microwave radiation. To model the damage, iPSC-CMs were separated into four groups and exposed to single or composite S-band (2.856 GHz) and X-band (9.375 GHz) microwave radiation sources with an average power density of 30 mW/cm2. After that, FCM was used to detect cell activity, and ELISA was used to detect the contents of myocardial enzymes and injury markers in the culture medium, and it was discovered that cell activity decreased and the contents increased after radiation. TEM and SEM showed that the ultrastructure of the cell membrane, mitochondria, and ID was damaged. Mitochondrial function was aberrant, and glycolytic capacity decreased after exposure. The electrical conduction function of iPSC-CM was abnormal; the conduction velocity was decreased, and the pulsation amplitude was reduced. Wb, qRT-PCR, and IF detections showed that the expression of Cx43 was decreased and the distribution of Cx43 at the gap junction was disordered. Single or composite exposure to S- and X-band microwave radiation caused damage to the structure and function of iPSC-CMs, primarily affecting the cell membrane, mitochondria, and ID. The composite exposure group was more severely harmed than the single exposure group. These abnormalities in structure and function were related to the decreased expression and disordered distribution of Cx43.

Background The heart is one of the major organs affected by microwave radiation and its effects have been extensively studied. In order to make the research model closer to human, we used iPSC-CM as the cell injury model to explore the biological effect of iPSC-CM injury after microwave radiation. Results First, the iPSC-CM was continuously cultured for 7 d after recovery, which was the best state for the cell model establishment. Second, to model the damage, cells were separated into four groups and exposed to single or composite S- and X-band microwave radiation sources with an average power density of 30 mW/cm2. After that, ELISA was used to detect the contents of myocardial enzymes and injury markers in the culture medium, and it was discovered that the contents increased after radiation. TEM and SEM were used to examine the aberrant ultrastructure. The abnormal changes in mitochondrial structure, an increase in the number of autophagosome-like bodies, and cell membrane rupture were discovered to be the most common signs of cell ultrastructural damage. The OCR was used to assess mitochondrial respiration. Mitochondrial function was discovered to be aberrant, with lower respiratory rate and ATP production. Wb, qRT-PCR, and immunofluorescence were used to detect expression and distribution of Cx43. The results showed that the expression of Cx43 was decreased, and the distribution of Cx43 at the junction of cell-cell was decreased. The composite exposure group was more severely harmed than the single exposure group. Conclusions Single or composite exposure to 30 mW/cm2 of S- and X-band microwave caused damage of structure and function of iPSC-CM, primarily mitochondrial damage, with a dose-dependent effect. The iPSC-CM is of great value in the research and treatment of heart diseases, especially in the research of microwave-induced cardiac damage.
