This study appears to be incorrectly categorized in the EMF research database, as the abstract describes nuclear physics research involving heavy ion collisions rather than electromagnetic field health effects. The research focuses on particle physics simulations and has no relevance to EMF exposure or biological systems.

This study examined whether thymidine could mitigate DNA damage and apoptosis caused by tumor-treating fields (TTFields), which use alternating electric fields for cancer treatment. Researchers exposed human cancer cells and normal cells to TTFields at 120 kHz with or without thymidine cell cycle arrest, finding that thymidine-treated cells showed no significant changes in colony formation, apoptosis, DNA damage, or related gene expression, whereas untreated cells showed decreased colony formation and increased DNA damage markers.

This study investigated how pulsed electromagnetic fields (PEMF) combined with piezoelectric scaffolds made from polycaprolactone-tricalcium phosphate coated with polyvinylidene fluoride (PVDF) affect bone cell growth and mineralization in MC3T3-E1 cells. The researchers found that PEMF at 0.6 mT and 50 Hz significantly enhanced cell proliferation, PVDF coating enhanced mineralization, and the combination of both PEMF and piezoelectric coating most effectively promoted late-stage osteogenic gene expression.

Researchers tested whether electromagnetic fields could help overcome chemotherapy resistance in aggressive brain cancer cells. They found that combining 50 Hz EMF exposure with the drug temozolomide killed more cancer cells and reduced their ability to spread. The electromagnetic fields appeared to make the chemotherapy more effective by changing how key cancer-related genes and proteins behaved.

Researchers tested 22 different extremely low frequency pulsed electromagnetic fields on immune cells called macrophages to see which ones could help fracture healing. They found two specific fields around 52 Hz that had opposite effects - one promoted inflammation while the other reduced it and enhanced healing factors. The anti-inflammatory field also helped stem cells produce proteins needed for bone repair.

This appears to be a bibliography or reference list from a 2021 veterinary journal focusing on viral diseases in reptiles and amphibians. The collection includes studies on various herpesviruses, ranaviruses, and other pathogens affecting turtles, snakes, and other cold-blooded animals. However, this reference list does not contain any research related to electromagnetic fields or EMF health effects.

This study compared how low-frequency electromagnetic fields (LF-EMF at 5 mT, 50 Hz) and high-frequency electromagnetic fields (HF-EMF at 2.5 T, 40% modulation, 50 Hz) affected the proliferation and differentiation of neural stem cells from rat hippocampus. Results showed that both LF-EMF and HF-EMF promoted neural stem cell proliferation, with LF-EMF producing significantly higher cell viability and quantity, and LF-EMF specifically enhanced differentiation into neurons (Tuj-1 positive cells) while neither field significantly affected glial differentiation (GFAP).

Researchers exposed mouse sperm stem cells to 50 Hz electromagnetic fields (like power lines) and found it caused oxidative damage and cell death. However, when they treated the damaged cells with protective molecules called exosomes from Sertoli cells, the damage was largely reversed. This suggests natural cellular repair mechanisms might help protect male fertility from EMF exposure.

Researchers exposed two types of human immune cells to pulsed electromagnetic fields of different strengths and found dramatically different responses. Cancer-derived immune cells showed beneficial anti-inflammatory effects at weak field strengths, while healthy immune cells required stronger fields but experienced cellular stress and increased cell death.

This study examined how radiofrequency field exposure at 1800 MHz affected testicular development in pubertal mice, comparing morning versus evening exposure times over three weeks. The researchers found that RF exposure reduced testicular weight, sperm production, and testosterone levels, while also altering long non-coding RNA (lncRNA) expression patterns that were associated with pathways involved in DNA damage, cell cycle regulation, and spermatogenesis.

Researchers exposed male rats to 2100 MHz electromagnetic fields (similar to 3G cell phone frequencies) and found significant damage to reproductive health, including reduced testosterone, lower sperm count, and increased abnormal sperm. However, when rats received selenium supplements alongside EMF exposure, most of the reproductive damage was prevented or reduced.

Researchers exposed male rats to 2115 MHz radiation (3G cell phone frequency) for 2 hours daily over 45 days and found significant damage to sperm count, motility, and testicular tissue. However, rats given pomegranate juice showed protection against this reproductive damage, suggesting antioxidants may help counteract EMF-induced fertility problems.

Researchers used EEG brain wave measurements to study how mobile phone electromagnetic radiation affects brain activity in real-time. They compared brain wave patterns when participants were not using phones versus when actively using them. The study found measurable changes in brain electrical activity during mobile phone use, suggesting the radiofrequency energy does influence neural function.

This study examined 266 college students using MRI to investigate whether brain grey matter volume in specific regions was associated with problematic mobile phone use (PMPU) and whether these brain regions moderated the relationship between PMPU and depressive symptoms. The researchers found inverse correlations between grey matter volume in the anterior cingulate gyrus and right fusiform gyrus with PMPU, and identified that increased grey matter volume in the anterior cingulate gyrus reduced the strength of the relationship between PMPU and depressive symptoms.

Researchers exposed mouse brain neurons to cell phone radiation at 1,800 MHz for 48 hours and found it significantly impaired the growth of neural connections (neurites) without killing the cells. The radiation disrupted a key cellular pathway called Rap1 that's essential for proper brain development.

Researchers exposed healthy and brain-injured mice to cell phone radiation to test effects on memory and anxiety. The radiation alone showed no significant impact on normal mice, but produced mixed results in brain-injured animals - improving visual memory while worsening spatial memory in females. The study highlights the complexity of EMF effects and challenges in drawing definitive conclusions.

Researchers exposed rats to cell phone radiation (900/1800 MHz) for 3 hours daily and found it caused brain cell death and oxidative damage in the hippocampus. However, rats that also performed moderate aerobic exercise showed protection against this radiation-induced brain damage, with significantly fewer dead brain cells and better antioxidant defenses.

This study examined how wireless-range electromagnetic radiation (EMR) affects sleep patterns in mice. The researchers found that prolonged exposure to 2.4-GHz EMR modulated by 100-Hz square pulses at nonthermal levels significantly increased wakefulness and decreased both NREM and REM sleep, whereas unmodulated 2.4-GHz EMR at the same average power level had minimal effects.

This study exposed male mice to L-band high-power microwave radiation at various power densities (0.5-1.5 W/m²) and examined resulting changes in brain function. Exposure at the highest power density (1.5 W/m²) induced cell apoptosis, cholinergic dysfunction, and oxidative damage in the hippocampus and cerebral cortex, with effects correlating to both power density and exposure duration.
