Macrophages under low oxygen culture conditions respond to ion parametric resonance magnetic fields - biomed 2011.

Macrophages, when entering inflamed tissue, encounter low oxygen tension due to the impairment of blood supply and/or the massive infiltration of cells that consume oxygen. Previously, we showed that such macrophages release more bacteriotoxic hydrogen peroxide (H2O2) when exposed in vitro to low oxygen than when cultured at usual ambient oxygen conditions. In this study, we use this low-oxygen, inflammatory macrophage model to test the macrophages’ response to low-frequency magnetic fields.

Dielectric properties of human skin at an acupuncture point in the 50-75 GHz frequency range: a pilot study.

The reason for using acupuncture points as exposure sites in some applications of millimeter wave therapy has been unclear. Acupuncture points have been suspected to exhibit particular direct current (DC), low-frequency electrical and optical properties compared to surrounding skin. To assess if such a biophysical correlation could exist at millimeter wave frequencies used in the therapy, we investigated the dielectric properties of an acupuncture point on the forearm skin within the 50-75 GHz range.
