  • Red Light and PEMF

    This post reviews a pilot study investigating the combination of optical and magnetic stimulation. (COMS) to treat chronic venous leg ulcers. . The devices used in this study may be replicated with commercially available magnetic and optical stimulation devices. The etiology of venous leg ulcers is complex. Treatments are usually compression stockings and other…

  • 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…

    near infrared and lymphatic vessels

    The essence of this post is that 1267 nm near infrared light (NIR)activates clearance of particles from mouse brains via the generation of the weakly reactive oxygen species singlet oxygen. This model is consistent with what we know about lymphatic vessel pulsing and singlet oxygen modifications to contractile proteins. The bigger question is if…

  • 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…

  • Smooth muscle relaxation

    This post is a spinoff post of red light for depression. Depression can be associated with poor cerebral blood flow. Much of the red light photo biomodulation discussion gets into the improved enzymatic activity of cytochrome C oxidase….which as a heme group. There are two heme containing enzymes that are essential for relaxation of…
