The centrifuge is rated at 4420 g.... (at least the one i was considering)
Let me see if i can find a similar one that tops out at 5000 gs.
The filtering... now that is something i am still looking at. Any suggestions on that end would be appreciated!
Cheers

BTW, there is still research going on in the field now known as 'Low Energy Nuclear Reactions' or some such thing. A lot has been learned since 1989. Unfortunately, the field is very greatly hampered by public perception that "Cold Fusion is a Fraud". It was never a fraud. A debacle, yes, but not a fraud, nor a scandal.

One thing that bothers me, though, is that the median life span of Wistar rats is known to be around 30 months. That the control rats lived for 22 months, so much less than the known median lifespan, rings alarm bells despite the small size of the study. For a study to be convincing, the known median lifespan should at least be approximated in the control group, otherwise it raises questions about any number of possible problems, for example related to husbandry, lack of blinding causing differential treatment between groups, size of study, etc.
If the difference is solely due to a size effect, and we ascribe the fact that the control group lived 30% shorter than the expected 30 months to be a non-significant statistical variation, then the fact that the buckyball group lived 30% longer than the expected 30 months is likely also ascribable to a non-significant statistical variation. This would void the claimed confirmation of the hypothesis, because given the wide error bar, there is a 50/50 chance that the outcome could have gone the opposite way.

A Japanese paper gives the average lifespans for male Wistar Mishima and male Wistar/Lobund rats as 731 days and 707 days respectively. That’s 24 months and 23 months, which isn’t far off from this set of male “Wistar” rats.

re: the biological mechanism underlying this Frickin'-Fuller rat study... The discussion thus far is beyond my DiY expertise (inflammation, especially of the 5-Lipoxygenase--5-LO--variety). That said, I have a few thoughts that others, more knowledgeable, might find useful. Tell me what you think.
First, and to get your attention, I note the following...
- Just a few months ago, the LEF made the case that 5-LO was implicated in 7 of the 10 most lethal diseases in the US.
- Faster than normal aging--10 times faster?--takes place during extended Space Flights. A study conducted on the International Space Station, published just a few weeks ago, found that 5-LO was implicated as a potential key cause of accelerated aging. Summary here.
- Well, and there’s this... For me, by 2009, the science underlying the importance of 5-LO had gotten to be so voluminous that I could no longer stand it and prepared an FB Note about the diseases it’s implicated in in December 2010, before the LEF article appeared.
Ok, so what does this have to do with this Frickin'-Fuller rat study?
I don’t have familiarity with the mtDNA literature to evaluate the relevance of the following. I just think these thoughts might be important and so I provide them.
- Olive Oil (EPA/DHA) is a profound inhibitor of the 5-Lipoxygenase--Leukotriene B4 Inflammatory Cascade. The point is... The Olive Oil choice as a solvent is not inconsequential to the study result.
- The OLIVE OIL--C60 Study authors say, in the abstract itself, they believe the result has something to do with attenuating OxIdative Stress.
- Oxidative Stress implicates ROS (Reactive Oxygen Species) are at work and Mitochondrial DNA impact (about which I know nothing).
- But mtDNA impact implicates P53, the Guardian of the Genome, right?
So this study should be noted...
---------
5-Lipoxygenase regulates senescence-like growth arrest by promoting ROS-dependent p53 activation
5-Lipoxygenase (5LO) is involved in the production of leukotrienes and reactive oxygen species (ROS) from arachidonic acid. Its strong activation has been associated with several diseases like cancer and neurodegeneration. Here we show that 5LO activity increases during senescence-like growth arrest induced by oncogenic ras or culture history in both human and mouse embryo fibroblasts. Overexpression of 5LO promotes senescence-like growth arrest via a p53/p21-dependent pathway, and this occurs independently of telomerase activity. 5LO stabilizes p53 through phosphorylation at Ser15 and increases expression of the p53-transcriptional target p21. This is achieved by regulating ROS production. Indeed, ROS are increased in 5LO-arrested cells. Antioxidants and a low oxygen environment prevent 5LO-induced growth arrest. Finally, 5LO inhibition reduces the growth arrest induced by oncogenic ras or culture history and these effects are neutralized by the addition of exogenous ROS. These data link the 5LO pathway to oxidative crises of primary fibroblast and suggest that the ability of 5LO to induce senescence-like growth arrest may be important in the pathogenesis of 5LO-associated disorders.
---------
I presume to post these thoughts, not because I understand how they’re relevant but because, just this year...
- the LEF says 5-LO is important
- an aging in space study says 5-LO may be a major driver of aging processes
- a study of aging finds that rats, high on C60 Fullerenes dissolved in a 5-LO inhibitor, get their life spans doubled.
Tell me, if you can, that this is not yet another study about the profound health effects of managing 5-LO...

I didn't get the impression from the space study that 5-LO was a major driver of aging processes. Maybe a minor one. There's at least one pretty decent 5-LO inhibitor already being used in humans. It's called Singulair, made be Merck. I took it for several years as part of my therapy for atypical asthma (allergy-driven inflammation without reactive airways). I didn't notice a thing from it, and eventually dropped it. It seems to me that if 5-LO inhibition was the magic bullet, I'd have seen something. My allergist claims that for some people, the effect of adding a 5-LO inhibitor is huge, but I wasn't one of them.

As for the relevance to the rat study, my question would be: Quantitatively, how potent a 5-LO inhibitor is olive oil? I don't think that's considered a major activity. That said, the vehicle controls lived a lot longer than the base controls. We know olive oil is good for us, but that result seemed too big. I consider that a problem with this small study, but maybe the rats really like being force-fed a bizarre variant of the Mediteranean diet.

niner... Thanks for the reply. Some thoughts...
- Singulair is a prescribed drug. There are innumerable natural 5-LO inhibitors of various types. Many healthy substances we take for granted as healthy are especially healthy just because they inhibit 5-LO. (Omega 3s, Cocoa, Curcumin, Boswellia, Quercetin, even Resvertatrol, etc.) I don't see that the use of a 5-LO inhibition drug is necessary until the natural means for inhibiting 5-LO have been exhausted.
- About the importance of 5-LO... I'm just recently back to this forum. I'll create a thread about 5-LO soon. In the meantime, I encourage those not familiar with how important it is to check out the first few links in my post above. (The LEF says 5-LO is implicated in 7 of the 10 most lethal diseases in the US.)
- Olive Oil is a 5-LO inhibitor. I don't have time now to post studies showing this. I can easily do that at some point if it needs doing. I thought I read that a high quality Olive Oil was used in the Buckyball study. That could make a difference.
- But my main point had been to emphasize the choice of a high quality, known 5-LO inhibitor as the solvent for the Fullerene C60s. This would NOT be relevant or interesting to the mechanism question of a presumed actual life span increase in this study's rats if multiple studies hadn't already found a relationship between 5-LO inhibition and a reduction in ROS with implied impacts on Telomeres and Telomerase.
- But 5-LO actually has been found to inhibit ROS in multiple studies. It is a profound inhibitor of TNF-a. Study links below about ROS inhibition.
- So my question/point is this... Could it be that some unique feature of the combination of a 5-LO solvent with the Buckyballs is what extended life span? I believe I read upthread that the Buckyballs might clump in the mitochondria for some extended period. If that's true, then the combination with the Olive Oil would maintain 5-LO inhibition in the mitochondria for that same period, hence, perhaps clearing out the ROS.
I'm not certain this is what's going on that explains a presumed actual life span increase. I'm not familiar with the language and the meaning of much of the science around mtDNA and telomeres. I'm merely putting this point on the table for discussion: Let's not forget the importance of the Solvent. 8-)

Olive Oil is a 5-LO inhibitor. 5-LO inhibition reduces ROS, independent of P53. I cannot escape the conclusion that the choice of the Olive Oil solvent, per se, cannot be dismissed as being unimportant to the Buckyball study conclusion. At least not yet.
Thoughts?

------------------
Anthony Loera: Might this be THE hint about HOW to think about the choice of a Solvent for the Fullerene C60s? The solvent must be a 5-LO inhibitor. Perhaps an even more effective one than Olive Oil exists?
I dunno. I'm just asking questions.

From results:
http://www.ncbi.nlm....cles/PMC188048/Although additional studies of the
mechanism of antiviral action of this compound are war-ranted, our results and those of Friedman et al. suggest that
the compound inhibits HIV-1 RT and DNA polymerase a
and selectively inhibits HIV-1 protease in cell-free systems
(Table 1) (6). This compound can be viewed as a lead in the
discovery of additional water-soluble fullerenes with greater
virucidal and antiprotease activities and should also stimu-late biochemical and pharmacological studies to determine
the metabolic disposition of this novel class of compounds in
living systems.

Another interesting article, pointing that nano-C60 (nC60) which is C60+water (not oil) complex, is toxic (oxidative), though toxicity can be prevented by adding ascorbic acid or other antioxidants. Other studies also talk about several hydrophilic C60 complexes being oxidative in presence of optical stimuli, will try to find those.
http://nanonet.rice....ytotoxicity.pdf
Notice that they first dissolved the C60 in tetrahydrofuran and their test to determine that there was none left seems suspect. If C60 dragged any THF into the mitochondria, that would not be good.

I am preparing a batch of C60/MCT oil with a concentration of 0.5 mg/mL for kicks. It has a much lower viscosity and should be easier to filter at least. The big question is whether there is something about olive oil that makes it so effective (assuming the rat study results are correct).
HappyPhysicist... I assume that by MCT Oil you mean Medium Chain Triglyceride Oil...
I take it from posts immediately prior to yours that the choice of solvent is not a trivial one.
To my way of thinking, here's what we know from the study we're discussing and from other sources...
- Olive Oil was used as a solvent
- Olive Oil is a 5-Lipoxygenase (5-LO) Inflammatory Pathway Inhibitor (google it to see for yourself)
- 5-LO inhibits ROS
- ROS inhibition has longevity implications (see the diagram I posted)
- To my mind, the links I've provided and the diagram I posted in my last thread provide a plausible *explanation* for the C60/Olive Oil study result
- The impact of 5-LO on ROS makes sense as a part of that *explanation*
I wouldn't do this experiment on myself, but I understand the rationale related to your health that is driving your effort. I would do the same thing if I were in your position.
That said, I think it's a misstep to use anything other than a clear 5-LO inhibitor as a solvent. WHY NOT use precisely what the study used (Olive Oil) when there is a plausible argument, derived from studies, for the solvent they used? Or, at least, WHY NOT use a solvent for which 5-LO inhibition pops up immediately when doing a google search?
I just don't see 5-LO inhibition popping out for MCT Oil. Maybe I'm missing something... If I am, I stand corrected... But, in that case, prove it to me... I hope you see the value in getting this kind of feedback...
Just my two cents... I hope my posts and thoughts provide you with feedback that provides benefit.
All my best to you and yours.

These are all good points. Why would one deviate from the C60 preparation in the rate study? Well, if it wasn't so had to prepare I wouldn't. What I like about MCT is that it is transparent and after mixing with C60 has the signature purple color of C60 solutions. This gives me an added level of comfort that the solution is prepared properly and if I decide to skip the filter and centrifuge steps at least the color is a good indication that the vast majority of C60 is dissolved and not in the form of aggregates.
There are just too many unknowns here to make an educated decision. Its all guesswork at this stage.

There are a lot of unknowns. I agree. There are also a lot things we do know. We know that the solvent choice is a non-trivial one...
You're taking some risk here in doing this n=1 experiment for understandable reasons. You're putting time and energy into doing this. IMHO, it's a mistake to take a short cut on the 5-LO oil question.
(My background for being able to say this: I've spent a couple thousand hours studying the 5-LO pathway. I have posted prolifically about this topic at Dr. Davis' TrackYourPlaque.com forum. I know more than a little about the importance of 5-LO. And (see the link in my first post) the LEF says its important too...)
Let's be clear... In using MCT Oil and given the evidence about the importance of 5-LO to human health and oxidation, you're NOT actually designing your experiment in a way that is consistent with the Buckyball study for a key study dimension, i.e., the solvent choice...
Tell me you're using an Omega 3 Oil... EPA/DHA... My response would be a positive one...
To be clear, my purpose here is not to give you a hard time for no reason but to provide you with informed feedback about a detail I have expertise about...
All the best...

The value of these forums and what make them in some ways superior to the traditional academic paradigm is the open real time debate, so I encourage this line of questioning. I only wish academics would engage is such open debate but I think their egos get bruised too easily.
You are definitely correct that I will likely learn little or noting by taking C60/MCT for a week, but I am going to give it a try anyway. Currently I am taking C3/OO (Olive Oil) and plan to do it primarily.
Thanks,

I believe WHAT you dissolve the Buckyballs in is more important than the HOW or the DEGREE of dissolving them... But I'm not going to preach about it any more.
Moving on.... Omega 3 Fatty Acids (EPA/DHA) inhibit 5-LO. Is it possible for you to shift your effort to Omega 3s? If you're just looking to vary the solvent, try some Omega 3 Oil you can purchase online...

I think there is something special about olive oil; most of the fatty acids are unsaturated. This may be particularly important in the case of the doubly (or higher) unsaturated fatty acids, which may engage in a Diels-Alder coupling with the fullerene, with the fullerene acting as the dienophile. I read somewhere about a mechanism whereby a fullerene could link to an
My working assumption at present is that C60 reacts with the fatty acids in various oils, forming what I think is the active species, a fatty acid C60 adduct that can become an integral part of a biological membrane, including the mitochondrial membrane. I need to learn a lot more about the chemistry of this reaction, the structure and stability of the adducts, and their biological fate before I can say that this is more than an educated guess.
[Further edit: As long as I'm editing, I'll note that in the lipid chart I posted somewhere below, it lists coconut oil as 91% saturated and 9% unsaturated. Therefore, you might still form adducts without resorting to peroxide chemistry.]

The experimental results show that the solubility of fullerenes appears to be dependent on the unsaturation level of the fatty acids composing the vegetable oils being lower in oils with higher unsaturation level. Franco Cataldo
Has anyone found a chart which orders the various oils in terms of "unsaturation" level?
It was already pointed out by someone in this forum that MCT is a pure saturated fat, and therefore has a low "unsaturation level" (If I understand that term correctly), and therefore should have a higher solubility of C60. The question is does the C60 still go along for the ride to the cells or mitochondria.

It's not at all clear what reacting C60 with a heated solvent would do, but it would surely act differently in vivo.

I think I confused myself. If 43 mg of C60 dissolve into 1 ml of Seabuckthorn Oil that would be over 50x the ratio of .8 grams of C60 dissolving into a liter of Olive Oil. Cutting the oil volume needed by a factor of 50 would make dosage quite practical. Too bad there's no research on C60 with Seabuckthorn Oil.

Something is not right. Cataldo's paper states a solubility of Castor oil, for instance, as 392 mg/l = 0.392 mg/mL, which is different from the Russian paper by about a factor of 100.
They're heating it, and when you heat it you get a reaction. Then it's not a true solution anymore.
