Nitric oxide, tissue oxygenation and photobiomodulation, how are they related?

It is interesting how diverse the view of nitric oxide (NO) can be. In the first post , I took information from a researcher who saw only positives. Not even a hint of a balanced view, the voice of a salesman of NO-generating supplements. This view is given by focusing on only one function of NO, namely vasodilation. Although this is an important function, it is not the only one that NO performs. An excess of NO is quite destructive, it permanently modifies enzymes and damages the function of, for example, the nervous system, as I have already commented on . In this post, I take information from one article that deals with the investigation of photobiomodulation. It is a relatively new field, where the tissue is irradiated either with LED radiation or a laser, or perhaps just with a broad spectrum of the sun or a light bulb. There is a lot of ambiguity here and the mechanisms of how it all happens are not known in detail at all. The positive effects are known, but the reproducibility

Is nitric oxide (NO) the cause of autism?

When I wrote in a previous post   that the cause of the suppressed ability to synthesize nitric oxide (NO) by the eNOS enzyme in our blood vessels in middle and old age could be its increased concentration in younger age, caused by insufficient exposure to ground-level ozone O3 in our surrounding environment, I had no idea that scientists had already begun to connect autism with an excess of NO. But we will look at this study later, first we will look at the statistics from Northern Ireland. Few countries have such well-processed data. I do not assume that the situation would be fundamentally different from, for example, the Czech Republic. The numbers are very alarming.  Nitric oxide as a cause of autism (ASD) Autism is characterized as a developmental disorder characterized by abnormal social interaction, constant repetitive patterns of behavior and impaired communication skills. The causes of autism are unknown, it is generally believed that a combination of genetic predispositions

Ozone and nitric oxide, how do they interact?

I already covered ozone in an older post. If you don't read it, l ook there first . Today I will try to supplement the previous considerations with the hypothesis of how ozone is formed in a clean outdoor environment. Fresh air in a clean outdoor environment unencumbered by emissions, far from traffic and industry, contains quite stable concentration, typically around 0.1 mg of ozone in one cubic meter. All day long, even at night when the sun doesn't shine. Human exposure to ozone over a 24-hour period is therefore much higher in a clean natural environment than in the vicinity of emission sources burning fossil fuels. There, the concentration of ozone drops sharply after sunset, sometimes below 0.02 mg/m3. The measured data clearly show this.
