Abstract

"Changes in cell hydration" have been hypothesized as an input signal for intracellular metabolic cascade responsible for biological effects of nonionizing radiation (NIR). To test this hypothesis a comparative study on the impacts of different temperature and NIR (infrasound frequency mechanical vibration (MV), static magnetic field (SMF), extremely low frequency electromagnetic field (ELF EMF), and microwave (MW)) pretreated water on the hydration of barley seeds in its dormant and germination periods was performed. In dormant state temperature sensitivity (Q 10) of seed hydration in distilled water (DW) was less than 2, and it was nonsensitive to NIR treated DW, whereas during the germination period (48-72 hours) seeds hydration exhibited temperature sensitivity Q 10 > 2 and higher sensitivity to NIR treated DW. Obtained data allow us to suggest that the metabolic driving of intracellular water dynamics accompanied by hydrogen bonding and breaking is more sensitive to NIR-induced water structure changes in seed bathing aqua medium than the simple thermodynamic processes such as osmotic gradient driven water absorption by seeds in dormant state. Therefore, cell hydration is suggested to be a universal and extrasensitive biomarker for detection of biological effects of NIR on cells and organisms.

Main findings

A comparative study assessed hydration of barley seeds exposed to distilled water pretreated by different temperatures and by nonionizing radiation modalities (mechanical vibration/infrasound, static magnetic field, ELF EMF, and microwave). In the dormant state, hydration showed Q10 < 2 in distilled water and was described as nonsensitive to NIR-treated distilled water, while during germination (48–72 h) hydration showed Q10 > 2 and higher sensitivity to NIR-treated distilled water. The authors suggest cell hydration as a sensitive biomarker for detecting biological effects of nonionizing radiation.

Outcomes measured

  • seed hydration
  • temperature sensitivity (Q10) of hydration

Limitations

  • Sample size not reported in abstract.
  • Exposure parameters (frequencies, field strengths, power densities/SAR, and exposure durations) not reported in abstract.
  • Study uses seeds and water pretreatment; generalizability to other organisms/cell systems is not established in the abstract.
  • Outcomes are hydration and Q10; no direct health endpoints are assessed.
