  • ICES traumatic brain injury

    ICES traumatic brain injury

    This post combines the preclinical results from a US company called Micro-Pulse and a very biophysical “letter to the editor” by a Danish company called Re5. The featured image of this post is a MicroPulse ICES waveform and one from Re5 supplemental data referenced in this post. It is assumed that the rise time…

  • 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…
