  • Singlet oxygen

    Singlet oxygen

    This is not a “feel good” post. Photodynamic therapy, photobiomodulation, can produce singlet oxygen. Just a little of a good thing can be healing. Over a certain threshold can lead to cell death. Three review articles have been shown to illustrate this phenomenon of why this is so. One thing that sets Red Light…

  • Transcranial red light

    Transcranial red light

    This post is a sister post to red light for depression, which asserts that red and NIR light help alleviate depression by increasing blood flow and functional connectivity. This post focuses on a theoretical study of Bhattacharya & Dutta 2019 exploring what it means to absorb red and near infrared (NIR) light. These authors…

  • PEMF fractured wrist

    I know someone who acquired a fractured distal radius. They are using a MagnaWave Semi -10. I always favored the Faraday’s Law of Induction for how PEMF works. A person may feel “things moving” for minor injuries, and more so for the fracture. I thought it appropriate to go over some nuances of the…

  • Radio frequency ablation

    Radio frequency ablation

    Radio frequency ablation uses radio frequency AC currents applied with a tissue inserted electrode. RF AC currents can generate RF electromagnetic fields in electrical wires via the “skin effect.” Current is most dense on the outside of the wire. This describes biopolymers like microtubules with their tubulin monomers (featured image). Radio frequency AC currents…

  • PEMF, green light, nitrate reductase

    PEMF, green light, nitrate reductase

    Nitrate reductase is a target of PEMF. This same enzyme absorbs in the green region of the visible spectrum that some biohackers like to use for healthy skin. .zeemi 2016 demonstrated that 538 nm green/yellow light resulted in maximal E coli growth reduction. Giordani & Buc 2004 demonstrated a 560 nm absorption band in…
