Seed Treatment with Electromagnetic Field Induces Different Effects on Emergence, Growth and Profiles of Biochemical Compounds in Seven Half-Sib Families of Silver Birch.

Research RF Safe Research Library Jan 1, 2023

This study evaluated a short (1 min) electromagnetic field (EMF) seed treatment in seven half-sib families of silver birch and assessed emergence, growth, and leaf biochemical profiles in one- and two-year-old seedlings. The abstract reports genotype- and age-dependent responses, with some families showing…

Changes in Free Radical Processes under the Influence of Low-Frequency Electromagnetic Field in Rats.

Research RF Safe Research Library Jan 1, 2022

This in vivo animal study examined how low-frequency electromagnetic field exposure affects antioxidant status in Wistar rats. The authors report frequency-dependent changes in antioxidant enzyme activity and hydroperoxide content in blood plasma. They also propose that LF EMF may stimulate low levels of ROS that…

The effects of the electromagnetic fields on the biochemical components, enzymatic and non-enzymatic antioxidant systems of tea L.

Research RF Safe Research Library Jan 1, 2019

This laboratory study examined how electromagnetic field (EMF) treatment affects biochemical and antioxidant-related components in tea samples, including flavonoid markers measured by HPLC. The abstract reports that 30-minute exposures generally increased several flavonoids compared with 60-minute exposures, with the…

Effect of electromagnetic fields and antioxidants on the trace element content of rat teeth.

Research RF Safe Research Library Jan 1, 2017

This animal study examined whether extremely low-frequency electromagnetic fields (ELF-EMFs) from a high-voltage source alter trace element concentrations in rat teeth and whether antioxidants (melatonin and glutathione) modify these changes. Rats were exposed 8 hours/day for 26 or 52 days, with separate sham…

Vitamin C and Vitamin E Protected B and Balb/c-3T3 Cells from Apoptosis Induced by Intermittent 50Hz ELF-EMF Radiation.

Research RF Safe Research Library Jan 1, 2017

This in vitro study exposed B cells and Balb/c-3T3 cells to intermittent 50 Hz power-line ELF-EMF and assessed apoptosis. The authors report that preincubation with vitamin C or vitamin E reduced apoptosis compared with the exposed group. They conclude that vitamins C and E have protective effects, with stronger…

[The specific features of the development of metabolic and regenerative processes under the action of low-intensity electromagnetic radiation in radiation exposure conditions (an experimental study)].

Research RF Safe Research Library Jan 1, 2017

This animal experimental study reports that low-intensity ultrahigh-frequency electromagnetic radiation and a low-intensity low-frequency magnetic field, applied after radiation exposure, enhanced metabolic and regenerative processes in rat testes and liver. The magnetic field was associated with increased…

Selenium supplementation ameliorates static magnetic field-induced disorders in antioxidant status in rat tissues.

Research RF Safe Research Library Jan 1, 2011

This rat study examined whether selenium supplementation modifies antioxidant-related changes associated with sub-acute static magnetic field exposure. The authors report that SMF exposure altered tissue selenium levels and antioxidant enzyme activities in a tissue-specific manner, including decreased selenium and…

The influence of low-frequency magnetic field on plasma antioxidant capacity and heart rate.

Research RF Safe Research Library Jan 1, 2009

This animal study exposed Sprague-Dawley rats to a 40 Hz, 7 mT time-variable magnetic field and measured ECG heart rate and plasma antioxidant capacity before and after exposure, including after 14 days. The authors report a significant decrease in heart rate after 14 days. Antioxidant defence findings were mixed,…

[Effect of Earth magnetic field on circadian rhythm of total antioxidant capacity of human saliva in the North].

Research RF Safe Research Library Jan 1, 2007

This paper reports observations in northern inhabitants relating geomagnetic conditions to circadian rhythm patterns in saliva total antioxidant capacity. It states that the amplitude of the circadian rhythm decreases during both increased geomagnetic activity and magnetic calm, with the most favorable rhythm display…
