Alex K Chen Posted June 6, 2020 Report Share Posted June 6, 2020 (edited) Since I know others might appreciate my output. Magnesium glycinate seems to be a killer supplement cuz it has BOTH magnesium and glycine.. It's hard to regularly dose too many supplements, and the core is taurine+carnosine+curcumin/piperine+B12+D+modafinil+green tea powder Edited June 6, 2020 by InquilineKea Quote Link to comment Share on other sites More sharing options...
TomBAvoider Posted June 6, 2020 Report Share Posted June 6, 2020 "My random notes/stream of consciousness thread" - I thought every thread you post is random/stream of consciousness? Why is it a killer supplement? What are the benefits of supplementing with magnesium if your diet is good (good diet applies to most on these boards)? Why is glycine a good thing to supplement with - we just saw a lengthy thread from Ron asking questions about glycine and it's a very complicated story with possible dangers of cancer when supplementing - you reference nothing of that complexity, you just make a random assertion with nothing behind it. Why is the "core" taurine+carnosine+curcumin/piperine+B12+D+modafinil+green tea powder? Seems a random collection of supplements with very, very complicated stories - you just mashed them together with nary a context... like stream of consciousness. In other words, as always, you drop these random questions or assertions with nothing behind them and no in-depth research and expect - I don't know what - that others will do all the research for you? Just random, random stuff. But whatever makes you happy - I'm just astonished to see you select this particular thread to call "random" and "stream of consciousness" when for the life of me I can't tell the difference - in the respect of randomness - from any other thread you post. Of course, it might just be for the club of those who "appreciate your output". Quote Link to comment Share on other sites More sharing options...

Gordo Posted June 6, 2020 Report Share Posted June 6, 2020 My theory is that InquilineKea is actually not a real person, but part of an elaborate AI experiment from someone in these forums. Quote Link to comment Share on other sites More sharing options...
TomBAvoider Posted June 6, 2020 Report Share Posted June 6, 2020 (edited) OMG, Gordo, that is super on the mark! I now am 100% convinced InquilineKea is an AI bot! The giveaway can be found in those experiments with bots trying to pass the Turing Test - the characteristic of those bots is that they never supply any new information or have any depth, but rather they "ask" questions - simply grab something a human says and turn it into a question so it looks sentient. Human: I had to solve a really difficult math problem to make this work. Bot: How did that make you feel? Human: It made me feel very tired. Bot: Why did it make you feel tired? And so on. This is InquilineKea in a nutshell - pointless questions with no followup and random remarks, and no original contribution. Mostly "questions". Gordo, you're a genious!

Dean Pomerleau Posted June 6, 2020 Report Share Posted June 6, 2020 OK Guys, You got me. Inquilinekea is one of my bots. 🙂 But seriously. We've been discussing who is Alex K Chen (aka InquilineKea) and why he asks so many questions for years. Here is one example. There is even a thread about him that I started in 2016 on the admin/moderator board for these fora called "Mr. Questions - Alex K Chen (aka InquilineKea)". We concluded he is harmless, and very occasionally makes thoughtful contributions rather than just asking questions (e.g. here). He was even active on the CR mailing list back to at least 2012 before these fora were created (search "simfish" Tom). We've had it easy for the last few years since Alex went quiet here around 2017. But he's continued to ask lots of questions (and answer quite a few) on Quora. His Quora profile shows he has asked 62K questions since 2013. Here is a good one. He's also very active on Reddit. I've even communicated with Alex via email. He asked if we might meet up during a visit he made to Pittsburgh a couple years ago. It didn't work out so I couldn't verify his humanity first hand. 🙂 If he's a bot, he is a very good one. I for one welcome our new AI overlords. 🙂 --Dean Quote Link to comment Share on other sites More sharing options...

But what do I know? It's not about "random damage", but specifically the multiple ways aging and disease result from "the accumulation of intra-intermolecular covalent bonds (crosslinks) between molecules with slow turnovers, such as collagen and elastin of the extracellular matrix (ECM) " This is not a new topic, of course, but the authors go into a lot of dimensions that haven't been discussed that much. FWIW, I'm not a a huge fan of Aubrey de Grey myself. Particularly wrt the business aspect of his endeavors. But I try to assess his scientific contributions individually and on their own merit, or lack of it, apart from his broader anti-aging philosophy and business model. In any case, de Grey merely made some " helpful comments on the manuscript ", so it would be silly to draw any conclusions from that acknowledgment, even from an ad hominem perspective. Perhaps your anti-Russian attitudes (well noted in the Calment controversy discussion) have predisposed you against this paper? Take a look at the full text; there are some interesting ideas there.

Perhaps your anti-Russian attitudes (well noted in the Calment controversy discussion) have predisposed you against this paper? Take a look at the full text; there are some interesting ideas there. Hm, but it is about random damage and it's presented as something groundbreaking: "However, the list of proposed hallmarks is missing the stochastic non-enzymatic modification of long-lived macromolecules. In this review, we summarized all evidence that it is in fact one of the primary, causative hallmarks." I perused the paper and it is a good overview, but I just don't see anything new in it, or at least in the part that they state is new. Nothing to do with it being Russian. And please don't assume that because I find the current leadership of Russia poisonous to its neighbors and to the world community, I hold anti-Russian views. On the contrary, I am a Russophile, in that I admire Russia's very significant cultural and scientific contributions to our world, and I have many close Russian friends. If anything, I feel disappointed and sad about Russia, because I really thought that things may have been different if the West had acted differently after the fall of the USSR. The US has not had a coherent strategic vision since the mid-1990s when Clinton essentially put Harvard's Institute for Int'l Development in charge of America's Russia policy and USAID, with little to no oversight. People like Summers propped up budding oligarchs like the Chubais clan and paved the way for Russian nationalism and distrust of Western "experts." And successive US administrations have not done better. The US should have promoted transparency in Russia, and helped integrate Russia into the world community, but it failed to do so. Swiss, German and British banks viewed Russia (and much of Eastern Europe) as a place they could make a lot of money and not play by the rules applicable within Western Europe. It was a recipe for disaster and we got it, in the shape of Putin and Russian nationalism. Anyway, I am digressing and this is not the place for it, but I find what happened in Russia really depressing, even though I like visiting.

It must monitor a basic process that underlies the ageing process, not the effects of disease. 3. It must be able to be tested repeatedly without harming the person, for example, a blood test or an imaging technique. 4. It must be something that works in humans and in laboratory animals, such as mice.

I'm curious to know because as Michael pointed out RBCs are replaced regularly and their life span is a relatively constant 120 days and does not differ much between humans so the age-distribution of the RBCs should be pretty constant. If you're thinking this has any implications for individual COVID-19 susceptibility I would think it has little effects unless somehow people can have a higher proportion of senescent RBCs without their average life span being significantly shorter than 120 days. Did the paper say anything about this? · Reply · 29m Olafur Pall Olafsson On a related note. If senescent RBCs play some kind of role in increasing risk for COVID-19 severity then donating blood regularly could be preventative inasmuch as it reduces the average age of the RBCs. Just throwing this out. I don't know if RBC senescence has anything to do with COVID-19 since I didn't read the full paper. Quote Link to comment Share on other sites More sharing options...

Alex K Chen Posted July 25, 2020 Author Report Share Posted July 25, 2020 Denis Odinokov JntuolooyldSr mtm2p1 hosrnsartlto h3:57 rdeASdM · Are you getting old yet counting on the cellular reprogramming or metabolic fine-tuning as on your personal savior? Blame yourself for wasting years believing that the cells can decide their fate freely from their environment (the long-lived components of the extracellular matrix) or some presumably nonrenewable intracellular components (such as the nuclear pore complex in post-mitotic cells). The crosslinks accumulation changes viscoelasticity, surface topography and chemical composition of the ECM, which in turn affect not only the cellular response to various biophysical stimuli, such as force, osmotic pressure, stretching, and shear stress but also cause multiple cellular dysfunctions, including the stem cell pool depletion. https://pubmed.ncbi.nlm.nih.gov/32540391/ Fedintsev A, Moskalev A.

As the breakdown of crosslinks might be something for physicists? Like radiation or nano robots? 1 · Reply · 4d · Edited Denis Odinokov Alex Inside though radiation making the ECM softer, it tears the collagen fibers across, not along. Not sure if such structural changes have any positive effect on the cellular fate 2 · Reply · 4d Alex Inside Denis Odinokov I am sure if it is possible, it should be radically precise resonating ray. 1 · Reply · 4d Denis Odinokov Alex Inside https://pubmed.ncbi.nlm.nih.gov/31069314/ PUBMED.NCBI.NLM.NIH.GOV Clinical doses of radiation reduce collagen matrix stiffness - PubMed Clinical doses of radiation reduce collagen matrix stiffness - PubMed 1 · Reply · 4d Марианна Карвэ Денис Одиноков химия жизни. · Reply · See Translation · 4d Denis Odinokov Марианна Карвэ вас тоже удивляет почему некоторые до сих пор не могут понять, что основа старения это химия, а биология лишь на подхвате 2 · Reply · See Translation · 3d · Edited Quote Link to comment Share on other sites More sharing options...
