I'm quite happy to engage in the subject matter. However no-one has contested anything mentioned in either of the videos, including you. What's there for me to do?Techno303 said:The thread is heated more so to do with how Jazzz handles science and less so to do with the premise.
He just posts up some half baked videos (which I have watched) and then states that his hypothesis must be true. This very much rattles the people on here, myself included, that are scientists.
At the very least if he is using some (all be it very poor) academic data he could be engaging in the subject matter a bit more and perhaps be discussing neuronal metal homeostasis, metal chelating, mechanisms for metal transport across the blood brain barrier, the role of zinc and copper in amyliod plaques for example.
Instead, as usual we get the usual hysteria, which is rather tiresome indeed.
Jazzz – engineer, physicist, mathematician, statistician, toxicologist and molecular biologist. I salute you.

why are they 'half-baked'? Do explain. perhaps then we'll have a discussion along the lines you are asking for.

everytime someone demolishes one of your pet sources, you just put your fingers in your ears, claim it's far more convincing than anything else and move rapidly onto more scattergun sources. See earlier in this thread where you used that silly questionnaire from a self-selecting sample as well researched 'proof' that removing amalgams was genuinely beneficial.
There's really no point reasoning with you
Do pay attention. It wasn't a questionnaire, it was a collation of studies. And if you read the later article I posted, it says there are documentation of over 60,000 cases of improvement in health after amalgam removal, never mind the 1000 in that collation.tarannau said:What's the point Jazzz? - everytime someone demolishes one of your pet sources, you just put your fingers in your ears, claim it's far more convincing than anything else and move rapidly onto more scattergun sources.

The concentration of mercury which was shown to mess up brain structure in that video was 10 to the power of minus 7, i.e. one part in ten million by weight.Techno303 said:Okay. The Calgary one doesn’t even have a hypothesis other then mercury is bad for cells. What is new here? Seriously?
Can you reference their publication that explains the method of the protein denaturing further?
What concentration of mercury are they pipetting in? I think I saw 7M flash on the screen?
They mention a link between the lesions formed by pippetting a high concentration of mercury directly onto the neuron and the types of lesions that occur in Alzheimer’s. This is spurious to say the least, not that anything conclusive can be drawn from a 5 minute video.
The amyliod plaques found in various types of neurodegenerative diseases are, I believe, rich in copper, zinc and iron. In fact copper tends to be the main culprit due to it having a high affinity to a certain protein (I’d have to go and look up which one this is). There is unlikely to be the same degree of affinity (the ability to tightly bind) to mercury. I must point out here that I am not an expert in neuronal metal homeostasis but I do collaborate with a leading expert and we both use techniques to investigate neuronal lesions.
All of this though, concerning mercury, is frankly moot until a feasible mechanism for mercury’s transport across the blood brain barrier is proposed. What are your thoughts on this? Have you looked this up in the literature? Mechanisms for mercury transport across the BBB would be the stuff of Nature papers? What about chelating, what are your thoughts on this considering the small amounts of mercury used in fillings?
So let’s stick with these themes:
1) Mercury delivery to the neuron
- mercury chelation and delivery across the BBB
2) Mercury uptake and binding with plaque forming proteins
3) How this compares to established problems with metal homeostatsis in neuronal degradation
No wriggling.

Clearly, if a relatively low concentration of mercury can cause brain degeneration, it doesn't matter whether there might be high concentrations of other metals present in plaques.
And that seemed to be well demonstrated in the video.
A quick google brought up this
mercury crosses blood-brain barrier which would suggest that mercury will cross the BBB by nerve transport.
Of course, this video is just concerned with neurotoxic effects.
What about chelation? Yes the body will chelate mercury. But it can only get such a proportion of what is in the body out, if I am right, mercury will have a high affinity for fatty tissues. The body's ability to chelate may also become compromised. In my case my glutathione level below normal even years after amalgam removal and supplementation with the amino acids which comprise it.

Techno303 said:Jazzz,
Also, would you just like to give me your thoughts on what the significance is between pipetting something directly onto a cell in vitro and something being uptaken and transported to a cell in vivo. Do you not see any problems in directly comparing the two? Does in vitro work represent in vivo?
thanks for the correction, yes the concentration is mols per litre.Techno303 said:No it doesn’t! It shows the amount pipetted as a concentration (you do know what a concentration is don’t you?) – 10^-7 M. That is 10 ^ -7 moles per litre mercury, or 100 nM mercury placed directly onto the dendrite. That IS a large concentration to be placing on a cell!
So what is new here?????
What do you mean by “brain degeneration”???
Where is the paper that that video is relating too?
It does matter what the concentration of other metals are in the plaques, because they represent that the homeostasis process has failed! It is HIGHLY significant that specific proteins in plaque formation have great affinity for copper and NOT mercury!
That google link shows fuck all! They speculate, using fish as a model, that mercury can enter CSF (they give no mechanisms in the paper by the way) and it was published in an environmental science journal!
I guess it likes the taste.How does mercury have a high affinity for fatty tissue?

BACKGROUND: There are a number of patients and health care professionals who believe dental amalgam restorations are a factor in a host of diseases and conditions. They have been influenced by anecdotal case reports in the medical and dental literature, research published in the refereed literature and media stories concerning the alleged dangers of amalgam restorations. METHODS: The author uses an evidence-based approach in analyzing the data both supporting and condemning the continued use of amalgam restorations. He reviewed the articles from both peer-reviewed and non-peer-reviewed sources and evaluated their relevance, research design and statistical analysis, as well as whether the conclusions follow from the data. CONCLUSIONS: There are numerous logical and methodological errors in the anti-amalgam literature. The author concludes that the evidence supporting the safety of amalgam restorations is compelling. CLINICAL IMPLICATIONS: Amalgam restorations remain safe and effective. Dentists should educate patients and other health care professionals who may be mistakenly concerned about amalgam safety.
Now, as I stated earlier I don't want to get into a debate about the safety of mercury fillings as it would take me several months to get up to date with all the literature and be able to make an informed judgment. Unlike some people I don't just blindly believe what appears on the internet
A fundamental error Jazzz! Now, what are your thoughts on that concentration? How does it relate to what could be leaching from filings and crossing the BBB? How do they equate this concentration with “chronic” exposure?Jazzz said:thanks for the correction, yes the concentration is mols per litre.
And we have to take their word on that.Jazzz said:The same concentrations of cadmium, lead, aluminium or manganese didn't seem to create any bother.
Jazzz said:Well it would seem to be your speculation that mercury does not cross the blood-brain barrier, please provide your source for that info.
Oh shut up you tit!Jazzz said:Precautionary principle demands that that is where the burden of proof lies.
