The goal of this post was to come to some sort of understanding as to who, why, and if we even care if pulsed electromagnetic frequency (PEMF) therapy increases phosphorylation (activation of extracellular signal regulated kinases (ERK). Kinases are enzymes that attach phosphate groups to the -OH groups of serine, threonine, and tyrosine amino acid side chains. This sequential tagging is called signal transduction. This matter is being investigated because if a dog is being treated with PEMF to improve bone and muscle health of an injured limb, what happens if the dog has cardiac hypertrophy? Sure, preventing muscle atrophy would be good, but we don't want the dog's heart increasing in mass more. In this investigation, it was included that ERK phosphorylation is increased in PEMF of cultured myoblasts [1] and electrical muscle stimulation in a rat hindlimb unloaded model. [2] On the other hand, PEMF fires through PI3 kinase in serum deprived osteoblasts.

PEMF and hemoglobin
PEMF is said to increase oxygen delivery to our bodies. Just exactly what does this mean? This post presents a hypothesis as to the molecular and electromagnetic mechanism as to how this occurs.
Melanin, ELF PEMF, ERK
This post explores the influence of 3-75 Hz PEMF on malanin synthesis in cultured melanocytes.
Blue light connectivity
The featured image of this post was complied from a post from allthingslighting. The blue LED light from many commercially available strips is not the cone blue light we typically think of but of melanopsin of ipRGC (Intrinsically photosensitive retinal ganglion cells). It should be noted that the photopigment, melanopsin, is in the cells that the photoreceptor rods… Continue reading Blue light connectivity
Red light and myopia
Myopia, also near nearsightedness because the afflicted individual sees near objects but has issues with far away objects, has been reviewed on Wikipedia. Wikipedia authors attribute the main factors as increased length of the eyeball and/or changes in the refractive index of the cornea. A few publications were found demonstrating that red light used to treat myopia… Continue reading Red light and myopia
