Kidney restoration with laser photobiomodulation
This is a novel study:
Lim et al @ Indiana University, USA investigated the therapeutic efficacy of laser photobiomodulation on oxidative stress in chicken kidneys during development:

LLLT using Light Emitting Diodes research list
Yet another NASA NIR LED therapy paper was published recently showing that LED treatment may be therapeutic to damaged neurons, this time in a Parkinson’s disease model. I thought some of you may not appreciate quite how much research has been conducted with LED’s so here is a list of 43 that I found on PubMed.
Near-infrared light via light-emitting diode treatment is therapeutic against rotenone- and 1-methyl-4-phenylpyridinium ion-induced neurotoxicity.

Parkinson’s disease is a common progressive neurodegenerative disorder characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta. Mitochondrial dysfunction has been strongly implicated in the pathogenesis of Parkinson’s disease. Thus, therapeutic approaches that improve mitochondrial function may prove to be beneficial. Previously, we have documented that near-infrared light via light-emitting diode (LED) treatment was therapeutic to neurons functionally inactivated by tetrodotoxin, potassium cyanide (KCN), or methanol intoxication, and LED pretreatment rescued neurons from KCN-induced apoptotic cell … Continue reading

Laser therapy improves vision in patients with Age-related Macular Degeneration
Low-level laser therapy improves vision in patients with Age-related Macular Degeneration.
Researchers at University of Heidelberg, Germany have conducted a clinical trial on 203 patients with AMD (age-related macular degeneration) and improved visual acuity for between 3 and 36 months.

Cold Laser Therapy Mechanisum : On the way to a unified theory
I just had chat with Mike Hamblin (Harvard Medical School). He described to me how he had this insight about Nitric Oxide being unbound from Cytochrome C Oxidase by light after reading an article in Nature about fire flies.
Hypoxic or stressed cells tend to be low in oxygen and high in NO
This NO is bound to to Cytochrome C oxidase and inhibits cell function
Light (at certain wavelengths, intensities and duration) knocks NO off Cytochrome C oxidase so the cell performs optimally again plus the NO causes a temporary increase in blood flow :-)

Photobiomodulation / Cold Laser Therapy / LLLT It’s time to name names
This week Lars Hode and Jan Tunér put out a call for some concensus on the name for this cold laser, low level laser, photobiomodulation thing that we do.They concluded by proposing Laser Phototherapy. I had some counter arguments:

Are the BBC drug pushers ?
The BMJ “Editors Choice” headline this week was “Key opinion leaders, your time is up”. The editor Fiona Godlee asked “Why is it considered normal for medical leaders to accept personal payment for promoting a company’s drug or device?” She was referring to the BMJ article “Drug Marketing” which interviews former pharma sales representative Kimberly Elliott about Key Opinion Leaders. “These people are paid a lot of money to say what they say,” she said. “I’m not saying the key opinion leaders are bad, but they are salespeople just like the sales representatives are.” “Influential doctors can earn up to $400 an hour”.
