This paper describes an exposure and microscopy system designed to continuously observe living cells during exposure to modulated RF-EMF similar to mobile phone signals. Using protocols where the same cells serve as controls before and after exposure, the system was validated with endocytosis measurements. Under 900…
Histologic evaluation of thermal capsulorrhaphy of human shoulder joint capsule with monopolar radiofrequency energy during short- to long-term follow-up.

This Level III therapeutic case-control study evaluated shoulder capsule histology after arthroscopic thermal capsulorrhaphy using monopolar radiofrequency energy, with follow-up from 3.5 to 62 months. Mid- and long-term mRFE groups did not differ from controls on several histologic categories (synovial layer, edema,…

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…
Proteomic analysis in human fibroblasts by continuous exposure to extremely low-frequency electromagnetic fields.

Jan 1, 2007
This in vitro study examined whether continuous extremely low-frequency electromagnetic fields (3 Hz, 4 mT for 3 hours) alter protein expression in human fibroblast cells using proteomics. The authors report that some protein expressions differed between exposed and sham cells. They identify reduced expression (about…
Exposure to an additional alternating magnetic field affects comb building by worker hornets.

Jan 1, 2007
This animal study reports that exposing worker oriental hornets in an artificial breeding box to an additional 50 Hz magnetic field (50–70 mGauss) altered comb construction compared with controls under only the terrestrial magnetic field. The abstract describes fewer cells and eggs, more deformed cell geometry, and…
Aerodynamically assisted bio-jets: the development of a novel and direct non-electric field-driven methodology for engineering living organisms.

Jan 1, 2007
This paper describes an aerodynamically assisted bio-jetting technique that processes living cells/organisms using differential pressure rather than an electric field. The authors report an operational window for stable jetting and near-monodispersed cell-bearing droplets. Cell viability after jetting was evaluated…
Biophoton emission of MDCK cell with hydrogen peroxide and 60 Hz AC magnetic field.

Jan 1, 2007
This in vitro study measured biophoton/chemiluminescence emission from MDCK cells after inducing reactive oxygen species with hydrogen peroxide. The authors report that photon emission increased with hydrogen peroxide dose and that photomultiplier tube measurements agreed with fluorescence microscopy observations.…
Electric field-induced astrocyte alignment directs neurite outgrowth.

Jan 1, 2006
This in vitro study examined whether astrocyte alignment induced by an applied electric field influences neurite outgrowth. Astrocytes were pre-aligned using a physiological-strength electric field (500 mV mm(-1)), and dorsal root ganglia cells were then seeded onto them. Neurite outgrowth at 24 and 48 hours was…
Biological effects of extremely low frequency electric and magnetic fields: a review
Research
RF Safe Research Library
Jan 1, 1977
This review summarizes reported biological effects of extremely low frequency (ELF) electric and magnetic fields, describing them as significant and often acting as stressors. Reported outcomes include metabolic, hormonal, and body weight changes in rodents, lethality at high exposure levels in mice and insects, and…
