So you're open to speculative studies involving only a couple dozen rodents, and yet you're ignoring the study which says that hgf is linked to cancerous metastases by making some ridiculous red herring about putting up when i just linked you a study indicating possible issues with activating hgf.
I don't see how that's relevant. This guy can take any substance he wants but resevertrol guy was just trying to make a point regarding the scientific question ability of this substance. People on this forum tend to have a very very strong selection bias. A study that supports a substance will be almost immediately accepted, but when a negative study is presented, the community feels the need to nit pick every small detail and reject it on that basis so the substance in question seems more promising. Science would normally consider a substance to be guilty until proven innocent, but this forum tends to think a substance is innocent until proven guilty.
resveratrol_guy,
Doubt it's fair to be passing judgement on someone who is trying to helps someone who the medical community has thrown their hands in the air over and given up on. I haven't read the whole thread but it's easy to say things of that nature when this isn't your partner. Perhaps your concern with scientific excellency might differ too if you had something like that happen to you.
More of the same distortion.
Look, if you're going to impugn my judgment with terms like "very very strong selection bias", then at least have the decency to show me one empirical result where rats did not show reduced cognitive deficit after Dihexa monotherapy. Otherwise, distance yourselves from commenting on my particular situation.
Quoting the most recent study
"Dihexa has recently been shown to augment the cognitive abilities of aged and scopolamine treated rats as assessed using the Morris water maze task (McCoy et al., 2013)."
There was nothing reported in that study that contradicted the prior study in this regard.
Put up or shut up.
These are just a couple of entry studies involving a few dozen rats; it doesn't sufficiently reflect safety or efficacy in humans at all. Is it promising and worth future research? Yes. Is it shown to be safe for human consumption now? Absolutely not.
For example, I noticed Dihexa supposedly increases expression of HGF, but other studies have shown that "Overexpression of HGF and c-Met, at both protein and mRNA levels, was correlated with depth of invasion, lymph node metastases and overall AJCC stage."
http://www.ncbi.nlm....pubmed/22495710
And from the study you linked
"Results indicate that it is this ability to activate HGF that is responsible for both the
marked synaptogenic and pro-cognitive activities of these compounds."
It could possibly accelerate latent cancer or maybe even lead to it, but we won't know until human trials and proper blood analyses and statistics. I certainly wouldn't take a risk on some random substance based on a couple of rat studies, especially since it messes with growth. Or it might cause cancer a few months or years down the road. But rats don't necessarily live long enough for those kinds of effects to become visible
I mean it seems like you're desperate to take this substance though and that anyone who questions this substance is attacking you or something. No need to get so defensive over a molecule. It's not distortion, it's caution.
I see. So since you can't put up and you can't shut up you change the subject.
Genius.
Again you're welcome to take whatever drug you'd like but this drug is certainly not safe and ready for consumption.
Sarcasm also doesn't help your argument at all. There's no need to get so defensive about an atomic configuration.
The guy who wrote the Dihexa FAQ and included, months ago, a link to cancer concerns about Dihexa is ignoring your links to cancer concerns about Dihexa? Not really.
Shoo, gnat.
So why are you so butthurt then about people claiming the scientific question ability of this substance? Clearly even you recognize it; that or your selection bias is blinding you.
First it was put up or shut up, which I did put up even though you apparently mentioned it earlier, and now it's an uncreative cliche. What's next?
Both you and resveratrol_guy crossed a line that, in ordinary circumstances would be merely a breach of etiquette but given the real world in which we live -- a world where monstrous busybodies roam free to wreak havoc on the lives of innocent people given the mildest pretext -- is inexcusable. This line has nothing to do with the information on the limitations and dangers of Dihexa and everything to do with the imputation of defects of judgement in others. Only one example of the multiple times you and resveratrol_guy have done this is your (not resveratrol_guy's) imputation that I ignored or was somehow upset by your presentation of the dangers of cancer -- an imputation that is ridiculous on the face of it.
Look, if I'm short with you its not just because you are engaging in otherwise mild breaches of etiquette -- were it not for the real world in which we both live -- but also because I have to work my ass off 12 hours a day 7 days a week not only caring for an HD wife but trying to make ends meet in our household by doing remote programming work directly competing with Indian programmers living at home with their extended clans -- a lifestyle that is not a feature of the much more individualistic West.
Responses like this take TIME.
Well I am sorry for difficulties and I hope dihexa turns out to be the safe and effective miracle drug you're looking for, but I fail to see how I breached etiquette, and then even if I did, how that could be considered inexcusable. That seems like a serious over exaggeration to me.
I assume, by judgement, you're referring to my comment about selection bias which you clearly did not take well. On this forum, it's very common for a person to see two entry level studies and conclude, therefore, that the drug must be safe and effective. Selection bias means--
"Selection bias refers to the selection of individuals, groups or data for analysis such that proper randomization is not achieved, thereby ensuring that the sample obtained is not representative of the population intended to be analyzed."
Two rat studies involving a couple dozen rats certainly does not achieve proper randomization, and therefore doesn't necessarily reflect the correct trend in the population intended to be analyzed, particularly since the studies addressed rats instead of humans. I mean it also seems weird that you're so opposed to judgments considering we both make judgments all the time; obviously you were making judgments about me as well such as making sarcastic, and condescending comments. I am not bothered by your judgments though.
Maybe I was wrong about you thinking that dihexa was safe and effective for rats and humans, but that's not an unreasonable assumption because of your comments throughout this thread, and the fact that many people on the forum do have selection bias. The goal of my posts wasn't to try and troll you or to make your already difficult life harder, or to insult you; we've all had selection biases at some points in our lives. Its a normal part of human nature. I have been guilty of selection bias occasionally as well.
