xentrac | if φ(3, n, 0) = 4, then you can calculate 4 - 3 = n = 1 | 00:00 |
---|---|---|
xentrac | if φ(3, n, 1) = 12, then you can calculate 12 / 3 = n = 4 | 00:00 |
xentrac | if φ(3, n, 2) = 81, then you can calculate log₃ 81 = 4 | 00:00 |
xentrac | but it's quite difficult to come up with a general way to solve φ(a, b, c) = d | 00:01 |
xentrac | consider, for example, that calcjulating φ(n, 4, 2) = 81 involves instead calculating ⁴√81 | 00:03 |
fenn | fwiw there is no general solution to even quintic polynomials | 00:03 |
xentrac | now there are clearly things that you have to express with loops and conditionals and mutation and so on | 00:04 |
xentrac | but by expressing things as algebraic formulas when you can, instead of using those more expressive and powerful constructs, you preserve more power of manipulation | 00:04 |
xentrac | finding zeroes of quintic polynomials is not particularly hard; you just can't do it with an equation | 00:04 |
xentrac | you need an algorithm instead | 00:05 |
xentrac | but there are lots of other things you can do with quintic polynomials that you can't do with general algorithms | 00:05 |
fenn | this isn't selling me on equations | 00:05 |
xentrac | heh | 00:06 |
fenn | your solutions for n explained what the ackerman function does a lot better than the wikipedia article did, though | 00:06 |
xentrac | it's basically the same thing that you were saying earlier about web pages | 00:07 |
xentrac | when a web page is expressed sufficiently abstractly, it's easy to manipulate it to appear as, for example, white text on a dark gray background | 00:07 |
xentrac | but when it's expressed with inline images replacing some of the text, you lose that manipulability | 00:08 |
xentrac | similarly when you express a relationship between some variables with an equation, instead of an algorithm to compute one of them from the others, you retain the ability to solve for any of the variables (with more or less difficulty: as you point out, quintics and above don't have closed-form equational solutions, but even the general closed-form solution for quartics is extremely fucking hairy) | 00:09 |
xentrac | so you should use the less expressive, but more manipulable, representation when you can | 00:10 |
fenn | why is "code" necessarily an algorithm? | 00:10 |
xentrac | well, I've been talking about code in Turing-complete languages as the alternative to equations | 00:11 |
fenn | parameters are undefined until a function is called | 00:11 |
xentrac | as to whether it's easier to read Q = 2 \pi \sqrt{V (\frac{L'} {S})^3} or | 00:12 |
xentrac | ______ | 00:12 |
xentrac | / L | 00:12 |
xentrac | Q = 2π \/ V (-)³ | 00:12 |
xentrac | S | 00:12 |
fenn | oh, of course it's harder to read when it's full of escape codes | 00:12 |
xentrac | I suspect that it's largely a matter of familiarity | 00:12 |
xentrac | escape codes? | 00:13 |
xentrac | you can name your functions without backslashes and use parens instead of {} if you like, I don't think it makes much difference | 00:13 |
fenn | but i would write Q = 2 * pi * sqrt(V * L_prime/S)^3 | 00:13 |
xentrac | I was addressing your earlier point about | 00:13 |

xentrac | "hieroglyphics" | 00:14 |
fenn | it still leaves unresolved what is pi and what is sqrt and how is L related to L_prime | 00:15 |
fenn | but at least i can type it into an irc channel | 00:15 |
fenn | or a python console | 00:15 |
xentrac | right | 00:15 |
fenn | oh i missed a ) | 00:16 |
fenn | too busy trying to decipher the \frac notation | 00:16 |
fenn | why does tex mix () and {} | 00:17 |
xentrac | () get typeset | 00:17 |
xentrac | {} is just for grouping | 00:17 |
fenn | ... and now i'm thinking (there's a difference?) | 00:17 |
fenn | because that's a typesetting markup, not code | 00:18 |
xentrac | yes | 00:18 |
xentrac | hmm, I should really leave the office | 00:19 |
fenn | i'd also argue that equations are a historical artifact of typesetting that has nothing to do with whether it's analytical form or algorithm | 00:19 |
fenn | move into your desk, save the planet! | 00:19 |
xmj | xentrac: i find latex-ish equations easy to read | 00:19 |
xentrac | I really think the serialization format is one of the less important things about them | 00:24 |
fenn | but it's the one that causes the most grief | 00:24 |
xentrac | the serialization of equations is a historical artifact of writing by hand instead of keyboard | 00:24 |
xentrac | I have a similar notation for algorithms when I write them on paper | 00:25 |
xentrac | x | y for "while (x) y" | 00:25 |
xentrac | xs | f(x) for "for x in xs: f(x)" | 00:25 |
xentrac | x | | 00:26 |
xentrac | a | b for "if (a) b; else c;" | 00:27 |
xentrac | | | 00:27 |
xentrac | oops | 00:27 |
xentrac | left out the c | 00:27 |
xentrac | f x for "def f(x):" | 00:28 |
fenn | isnt x | y the same as a | b | 00:29 |
xentrac | k x y for "class k: def __init__(self, x, y): self.x = x; self.y = y" | 00:29 |
xentrac | --------- | 00:29 |
xentrac | no, the a | b one has a horizontal line underneath it | 00:29 |
fenn | heh "k x y" is some semantic sugar i wouldn't mind | 00:30 |
xentrac | and I use funky hieroglyphs and Greek letters for variables instead of entire words that I have to write out each time | 00:30 |
xentrac | yeah, a double underline is a lot easier to write in my notebook than the word "class" | 00:30 |
fenn | it's nice to be able to specify default values tho | 00:30 |
fenn | so i write a lot of stuff in my log books, but i use long form because i know i'm going to type it in eventually | 00:32 |
fenn | i could use some shorthand but i know i'll forget what it means | 00:32 |
xentrac | hmm I think I was using @x for self.x at some point | 00:32 |
xentrac | I should go back and formalize that notation | 00:32 |
fenn | @ is self.a :P | 00:32 |
xentrac | yeah, but I mean | 00:33 |
xentrac | k @x @y (doubleunderline) | 00:33 |
xentrac | by putting self.x (@x) in the parameter list itself, I'm implicitly assigning to self.x | 00:33 |
xentrac | but maybe that's not really necessary | 00:34 |
fenn | if you're using both x and self.x you're probably doing something wrong | 00:34 |
xentrac | yeah | 00:34 |
xentrac | I just mean, is it worthwhile being explicit about storing variables for later use? | 00:35 |
fenn | "Be liberal in what you require but conservative in what you do" | 00:35 |
fenn | this is more of what i was going for | 00:35 |
xentrac | because it's kind of an important semantic clue to intent | 00:35 |
xentrac | okay now I really am going to go home | 00:36 |
xentrac | I was really going to go to bed before 5 AM | 00:36 |
xentrac | fail | 00:36 |
fenn | g'night, and good luck | 00:36 |
xentrac | you too | 00:36 |
fenn | huh, weird. "In her talk The Science of Insecurity, Meredith Patterson makes the point that the principle of least power is important for security of interfaces which may be exposed to attack." | 00:45 |
fenn | i always thought "principle of least power" in a security context meant you rescind privileges not required for the task at hand, guess it's more abstract than that | 00:46 |

xmj | ebowden: these days i'm member of the freebsd development team so let's relativize the 'original purpose' a bit :D | 07:15 |
ebowden | :D | 07:15 |
eudoxia | i thought freebsd was pretty cool when i tried it | 07:15 |
xmj | it is | 07:16 |
ebowden | Cluckj, what? I haven't heard of bird deaths linked to that. | 07:16 |
cluckj | oh | 07:16 |
cluckj | pet birds are really sensitive to teflon off-gassing | 07:16 |
xmj | meh | 07:17 |
xmj | cluckj: You can't make any decent food in teflon pans anyway | 07:17 |
ebowden | I do prefer iron. | 07:17 |
xmj | cast! | 07:18 |
ebowden | Yes. | 07:18 |
ebowden | I do prefer cast iron. | 07:18 |
cluckj | no way, I have a teflon crepe pan that is magic | 07:18 |
xmj | what's magic about it? | 07:18 |
cluckj | ...nothing sticks to it? | 07:18 |
xmj | dude | 07:18 |
xmj | nothing sticks to a well-used cast-iron pan either | 07:19 |
cyberman | my teflon pot is so slick it slides off the burner | 07:19 |
cluckj | lol | 07:19 |
ebowden | LOL | 07:20 |
cluckj | you can't use the cast iron for everything | 07:20 |
ebowden | I wonder if they sell DLC coated pots. | 07:20 |
ebowden | DLC is diamond like carbon. | 07:20 |
ebowden | *diamond-like | 07:21 |
cluckj | the problem with cast iron is that to get nothing to stick to it, you have to heat it up to the right temperature | 07:23 |
cluckj | for delicate or thin things like crepes, that's too hot | 07:23 |
ebowden | LOL: http://news-hound.us/a-tattoo-artists-revenge-on-his-cheating-girlfriend-poop-tattoo/ | 07:24 |
ebowden | So, in other words, if you have it too hot, it all goes to, well, that girl's tattoo. | 07:26 |
ebowden | Is that right? | 07:26 |
cluckj | lol | 07:26 |
cluckj | ya | 07:26 |
cluckj | I don't really use teflon pans for much of anything else | 07:27 |
ebowden | Also, that is the most hilarious getting-back-at-cheating-partner story I've ever heard. | 07:27 |
ebowden | Ah, ok cluckj. | 07:28 |
ebowden | It was a whole back tattoo as well. | 07:28 |
ebowden | A big pile of poo with flies buzzing around it. | 07:29 |
ebowden | *whole-back | 07:29 |
cluckj | seems harsh | 07:29 |
ebowden | It was with his oldest friend. | 07:30 |
ebowden | And it was hilarious. | 07:30 |

We show that ultrasound significantly modulated AS latencies." | 16:24 |
kanzure | "Such effects proved to be dependent on FUS hemifield of stimulation (relative latency increases most for ipsilateral AS). These results are interpreted in terms of a modulation of saccade inhibition to the contralateral visual field due to the disruption of processing across the frontal eye fields.

dingo | you can use -current, as its called, pretty reliably | 18:21 |
dingo | you commit after testing | 18:21 |

dingo | its a very polished development lifecycle | 18:22 |
dingo | git or cvs, it doesn't matter at that point | 18:22 |
dingo | its the actual release cycle that matters | 18:22 |

kanzure | i wonder if the reason why we don't have an elaborate map of "we stimulated these neurons in the brain here" <-> "we got these results" is because nobody knows which tests to put the rats/monkeys/people through | 18:38 |
fenn | yeah "these results" is highly subjective | 18:38 |
kanzure | also, maybe 1 mm^2 is not enough for doing selective memory elicitation in humans | 18:39 |

kanzure | if you ask your stereotypical transhumanist what they would want to try to stimulate, they would say "my ability to solve word problems faster" | 18:46 |
fenn | more of objective performance tests (not more-objective tests, they're either objective enough or not objective at all) | 18:46 |
kanzure | but their answer- whatever it is- in most situations iwll not be directly controlled by a specific region of the brain | 18:46 |
fenn | of course not | 18:47 |
fenn | stimulating neurons is like sticking a wire into a computer and hoping something interesting happens | 18:47 |
kanzure | things that i am certain could be stimulated: memory elicitation (at minimum, generic playback of random crap), auditory input, visual input, motor cortex output, arousal, somatosensory crap, dyslexia (i mean, reading/comprehension can probably be disrupted) | 18:48 |
fenn | sure | 18:49 |
pasky | mm, a ham sandwich | 18:49 |
fenn | oops :P | 18:49 |
kanzure | i suppose that might be enough to work with | 18:49 |
fenn | also motor cortex input should be fun | 18:50 |
kanzure | that's been working in rats (or mice? sigh) | 18:50 |

Lemminkainen | I didn't name it | 21:37 |
Lemminkainen | I did, however, name a line of transgenic mice "butt exploder" | 21:37 |

gradstudentbot | I am kind of curious what he has a Ph.D. in, I can't really find this anywhere, it could be underwater basket weaving for all I know. | 21:38 |

fenn | Lemminkainen: see, that's the kind of descriptive naming we need more of in science | 21:39 |

fenn | they covered a glob of meat in clay, baked the clay ball in coals for like 2 days, then broke open the clay and powdered the now-ultra-dry meat | 22:09 |
xmj | turns out i want more fish and less beans. otherwise i'm in the good | 22:09 |

jrayhawk | i suppose green plantains are more magical | 22:10 |
fenn | anyway i tried to find a commodity source of saturated fat; lard has been polluted with omega-6 and beef suet is super oxidized | 22:10 |
fenn | coconut oil melts at a very low temperature, so i guess that leaves cocoa butter | 22:11 |
fenn | maybe mix carnauba wax and coconut oil | 22:11 |
jrayhawk | tropical traditions sells five gallon buckets of coconut oil for $100-150 depending on quality | 22:11 |
jrayhawk | I also have a five gallon bucket of grass-fed tallow from US Wellness meats, but I feel sorta crappy if I try to use it as a staple calorie source. | 22:12 |
gradstudentbot | I really like him, but some of his work is really problematic. | 22:12 |
fenn | is beeswax edible? | 22:12 |
fenn | i mean it probably wont kill you, but eating nothing but beeswax + coconut oil for months? | 22:12 |
jrayhawk | these days I mostly just buy ten pound bags of frozen grain-finished ground beef suet. | 22:13 |
jrayhawk | seems to do okay | 22:13 |
fenn | where do you get suet? | 22:13 |
jrayhawk | Special order from grocery stores. $1-2/lb | 22:14 |
fenn | that's pretty cheap | 22:14 |
fenn | that's cheaper than paraffin | 22:14 |
jrayhawk | I'm sure I could get it for less if I bothered to get to know any local cattle farmers or butchers. | 22:14 |

fenn | ok, just a headache, but it was clearly caused by the suet | 22:15 |
jrayhawk | Yeah, most of that stuff is stored room temperature in transparent packaging for long periods of time. | 22:15 |
jrayhawk | Beef suet should be frozen and fresh and stored in a dark freezer. | 22:16 |

fenn | man the wikipedia article on gliadin sucks | 22:50 |
xmj | It's wiki. Improving is allowed as long as you bring the [[quotation needed]] | 22:50 |
fenn | prolamine isn't a functional description | 22:50 |
fenn | "Prolamines are a group of plant storage proteins having a high proline content" | 22:51 |
fenn | okay but what does it do | 22:51 |
xmj | rewrite it | 22:51 |
jrayhawk | stores nitrogen, elastically binds to basically everything | 22:51 |
fenn | okay so zein from corn | 22:52 |
fenn | zein, a prolamine, is it found in cow's milk? | 22:52 |
xmj | sigh | 22:53 |
xmj | "Eliminate dairy" basically means "No cream in my coffee" which will be hard. | 22:53 |
jrayhawk | the nitrogen content makes it extremely valuable, the proline content makes it nigh-indigestable, the random binding affinities make it highly immunogenic, and the incredibly long nature makes it mechanically complicated (similar to the albumin family) | 22:53 |
jrayhawk | dairy protein is the (potential) issue; cream is probably fine | 22:54 |
xmj | hm. | 22:54 |
jrayhawk | ghee is also pure fat | 22:54 |
fenn | chocolate or coconut oil, probably want an emulsifier like egg yolk | 22:54 |
xmj | how's there no protein in cream? | 22:54 |
xmj | how come* | 22:54 |
jrayhawk | Cream is what rises to the top; it's fat. Solids sink. | 22:56 |
gradstudentbot | So, people always joke about that, but I feel like weaving baskets underwater would not be the easiest thing in the world. | 22:57 |
fenn | cream contains 2% protein, probably mostly whey | 22:57 |
xmj | hm | 22:57 |
xmj | that'd make sense. | 22:57 |
fenn | "solids sink" isn't quite accurate when talking about milk protein | 22:58 |

fenn | and whey just stimulates IGF because of its amino acid profile | 23:00 |
jrayhawk | Induces autoimmunity in some folks. | 23:00 |
fenn | or something | 23:00 |
fenn | why would dairy protein induce autoimmunity | 23:00 |
jrayhawk | Don't know; intestinal permeability is a very new field. | 23:01 |
jrayhawk | I mean, the stupid answer is "varying levels of adaptation based on genetics" | 23:01 |
jrayhawk | but it's not a particularly satisfactory one. | 23:01 |
fenn | we know that gliadin causes intestinal permeability, so maybe there's something like gliadin in milk (and maybe it isn't casein or whey) | 23:01 |
fenn | that's why i brought up lectins (I read this page but it didn't really "stick" http://krispin.com/lectin.html ) | 23:03 |
fenn | "Glucosamine is specific for wheat lectin and it is this specificity that may protect the gut and cartilage from cell inflammation and destruction in wheat (or gluten) responsive arthritis." | 23:03 |
jrayhawk | There may also be something about galactose and intestinal dysbiosis. | 23:04 |
jrayhawk | Yeah, I liked that theory a lot. | 23:04 |
jrayhawk | anti-TTG is heavily involved in arthritis, so stopping both the permeability and the specific antigen response would sure make sense for improving joints | 23:05 |
fenn | i mean, cows eat grains, and they probably also have intestinal permeability, so it's not unreasonable that there's plant proteins in their milk | 23:05 |
fenn | plus cow blood in the milk | 23:05 |
jrayhawk | huh http://www.ncbi.nlm.nih.gov/pubmed/23626786 | 23:06 |
fenn | well there you go | 23:06 |

fenn | i'm sure getting your milk from one cow is better than from 1000 cows all mixed together | 23:09 |
jrayhawk | one of the more amusing things is that people without lactase persistance genes can still adapt to pretty heavy dairy consumption just due to gut flora | 23:09 |
gradstudentbot | These findings indicate that extensive genetic engineering of human hematopoiesis can be achieved with lentiviral vectors. | 23:09 |
fenn | i definitely couldn't tolerate milk after being vegan for several years | 23:09 |
fenn | or cheese | 23:10 |
jrayhawk | Cheese is the highest protein form of dairy. | 23:10 |

fenn | no, they just don't have "industrial garbage" on them | 23:19 |
Lemminkainen | you're stringing together distal correlations into a misguided idea of causality here | 23:19 |
fenn | i think the causality of cancer is anything but clear | 23:19 |
jrayhawk | Lemminkainen: warburg effect; mitochondria overloading causes mitochondrial damage causes cancer | 23:20 |

xmj | entelechios: you don't | 23:29 |
xmj | openbsd has nginx in base, and afaik it's not statically linked. | 23:29 |
entelechios | well, i did, because that's the only way i coulda gotten our mailserver working again | 23:29 |
dingo | entelechios: hates openbsd like i hate djb's software | 23:29 |
xmj | stop spilling bullshit non-information. | 23:29 |
xmj | :( | 23:29 |
Lemminkainen | fenn you can definitely think about why people get sick; I've met a lot of people lately with the MTHFKR mutation in glutamate metabolism who are self-medicating quite well for it | 23:29 |
entelechios | not my decicions here to use that | 23:29 |
entelechios | is it in 5.5 base? | 23:29 |
xmj | it's obvious you're talking out of your ass when you reveal you don't know the difference between statically versus dynamically linked. | 23:29 |
Lemminkainen | but it takes a LOT to actually induce a huge pathology in almost anyone | 23:29 |
entelechios | if it is i'd way rather be seeing that used | 23:30 |
Lemminkainen | multiple mutations usually need to happen to induce cancer or some other disease pathology | 23:30 |
fenn | Lemminkainen: self medicating how? | 23:30 |
dingo | entelechios: if you're doing your job, then just do it -- if you're doing something for a home hobby, then chose something you want to work with | 23:30 |
jrayhawk | Cancer is not a disease of somatic mutation. | 23:30 |
entelechios | nope just doin my job | 23:30 |
jrayhawk | It is a metabolic disease. | 23:30 |
entelechios | and eh i enjoy it | 23:30 |
entelechios | i got a big old bonus | 23:30 |
entelechios | and a raise | 23:30 |
entelechios | out of the past couple weeks of bullshit from that on top of other things | 23:31 |
dingo | if you were a surfer, you'd be mad that the waves sucked today, or it was too cold, or nobody appreciates your surfing style, or the how the lifeguards are always telling you to go somewhere else, etc. etc. | 23:31 |
entelechios | lol some surfer bitching about how people dont appreciate his surfing style deserves to get attacked by sharks | 23:31 |
fenn | anyway there are large percentages of the american populace who are ill, it's not due exclusively to genetics (unless you consider the GLO- mutation "genetics") | 23:31 |
Lemminkainen | jrayhawk wut cancer is not somatic? | 23:31 |
jrayhawk | Cancer is mutagenic; mutagenesis is not the primary cause of cancer. | 23:32 |
ebowden_ | By the way, can errors in protein synthesis trigger cancer? | 23:33 |
entelechios | and the biggest reason i found it a pain in the ass was having to pull down via cvs the base src | 23:34 |
entelechios | i don't live in a country with fast internet | 23:34 |
entelechios | so that meant some late as shit overtime | 23:34 |
entelechios | cvs heh | 23:35 |
Lemminkainen | jrayhawk you'll need to provide a source on that claim | 23:35 |
xmj | entelechios: like git would be faster. | 23:35 |
entelechios | xmj, usually it is | 23:36 |
entelechios | eg pulling down chromium sources | 23:36 |
entelechios | thats gigashits worth | 23:36 |
fenn | Lemminkainen: he's just referring to the warburg hypothesis | 23:36 |
entelechios | and defintely takes less time via git than svn | 23:36 |
jrayhawk | Thomas Seyfried and Eugene Fine are the trailblazers on that front, AFAIK | 23:36 |
xmj | entelechios: i got 200mbit/s downstream, i don't care about your DVCS bikeshed | 23:37 |
entelechios | i'm pulling a guess out of my ass here but maybe it opens a new conn per file | 23:37 |
entelechios | welcome to costa rica, can i serve you your opulence on a silver platter poisoned for your gringo ass? | 23:37 |
xmj | dingo: is entelechios always like that? | 23:37 |
entelechios | no i don't really talk often in here | 23:37 |
xmj | bikeshedding around non-issues, for instance? | 23:37 |
gradstudentbot | I think I'll be done in 4 years. | 23:38 |
xmj | Marketing and Sales determined that the optimal bikeshed color is 'transparent'. | 23:38 |
xmj | ... hence overruling engineering which claimed it was 'blue'. | 23:38 |
xmj | 'Blue' obviously does not sell that well as Sales lacks selling rigor for it. | 23:38 |
jrayhawk | http://www.biomedcentral.com/content/pdf/1743-7075-7-7.pdf is probably the definitive paper | 23:39 |
entelechios | my bikeshed is made of abalone shells | 23:39 |
fenn | entelechios: git packs diffs into blobs and compresses them | 23:39 |
entelechios | ah that's the ticket then | 23:39 |
jrayhawk | http://robbwolf.com/2013/09/19/origin-cancer/ is an okay layman article | 23:39 |
entelechios | anyways slang english isn't my forte wtf is a bikeshed | 23:40 |
-!- Vutral [~ss@mirbsd/special/Vutral] has joined ##hplusroadmap | 23:40 | |
entelechios | ahh i urbandictionaried it | 23:40 |
fenn | entelechios: http://bikeshed.com/ | 23:40 |
entelechios | bikeshed: anything to do with openbsd ever on irc | 23:40 |
fenn | yeah | 23:41 |
entelechios | still makes a fantastic mailserver and firewall OS | 23:41 |
entelechios | anyways i now know why git does its thing faster and saves me time | 23:42 |
entelechios | thanks for the information fenn | 23:42 |
fenn | that is the least important feature of git | 23:42 |
entelechios | agreed | 23:42 |
fenn | michael ristow showed that exercise induces oxidative stress; cancer cells are operating at the edge of metabolism (which is why they need to use lactic acid metabolism) and are vulnerable to just a little bit more oxidative stress | 23:44 |
fenn | i met a plasma physicist at berkeley studying cold oxygen plasmas; they were testing it on cancer, haven't investigated it since then | 23:45 |
-!- Vutral [~ss@mirbsd/special/Vutral] has quit [Ping timeout: 246 seconds] | 23:45 | |
entelechios | i eat a block of dark chocolate per week | 23:45 |
entelechios | national tradition | 23:45 |
fenn | .title https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3241555/ | 23:45 |
yoleaux | Cold plasma selectivity and the possibility of a paradigm shift in cancer therapy | 23:45 |
fenn | a) cold plasma application selectively eradicates cancer cells in vitro without damaging normal cells; and (b) significantly reduces tumour size in vivo. | 23:46 |
entelechios | that's pretty cool | 23:46 |
fenn | i think they have plasma based hand sterilizers for doctors who are tired of washing their hands all the time | 23:47 |
fenn | it's a pretty simple device really | 23:47 |
jrayhawk | cryolipolysis also seemed like a cute concept | 23:47 |
jrayhawk | disproportionately apoptoses non-metabolic cells, stimulates BAT to eat up the result | 23:48 |
-!- Zhwazi [~Zhwazi@copyfree/contributor/Zhwazi] has quit [Ping timeout: 252 seconds] | 23:48 | |
fenn | you inhale the oxygen plasma for cancer therapy, it's not a magic wand | 23:49 |
fenn | what's BAT? | 23:49 |
fenn | oh brown adipose tissue | 23:49 |
entelechios | so am i talking to oncologists in here at all? | 23:49 |
jrayhawk | Brown adipose tissue. | 23:49 |
entelechios | anyone here familiar with some stuff done some years ago on inhibiting nitric oxide pathway controls | 23:50 |
entelechios | to prevent radiation damage in mice | 23:50 |
fenn | "the term Cryolipolysis is trademark-protected" | 23:50 |
fenn | that seems unfair | 23:50 |
jrayhawk | hah | 23:51 |
fenn | entelechios: you mean just antioxidants? | 23:51 |
entelechios | nah this was something specific | 23:51 |
entelechios | lemme dig around for what i had in mind exactly | 23:51 |
fenn | .title http://stm.sciencemag.org/content/1/3/3ra7.abstract | 23:52 |
yoleaux | Radioprotection in Normal Tissue and Delayed Tumor Growth by Blockade of CD47 Signaling | 23:52 |
entelechios | http://www.dotmed.com/news/story/10571 | 23:52 |
entelechios | this was it i think | 23:52 |
entelechios | yeah | 23:52 |
entelechios | that was it | 23:52 |
entelechios | neat stuff | 23:53 |
fenn | i thought CD47 was a killer t-cell receptor | 23:54 |
fenn | what does that have to do with NO | 23:54 |
entelechios | http://en.wikipedia.org/wiki/CD47 | 23:55 |
entelechios | http://en.wikipedia.org/wiki/CD47#Angiogenesis | 23:55 |
fenn | "However, these isoforms are highly conserved between mouse and man" techno sample | 23:56 |
fenn | paperbot: http://stm.sciencemag.org/content/1/3/3ra7.abstract | 23:57 |
paperbot | http://libgen.org/scimag/get.php?doi=10.1126%2Fscitranslmed.3000139 | 23:57 |
fenn | ah jeebus | 23:57 |
fenn | let's try that again | 23:58 |
fenn | paperbot: http://stm.sciencemag.org/content/1/3/3ra7.full | 23:58 |
paperbot | http://libgen.org/scimag/get.php?doi=10.1126%2Fscitranslmed.3000139 | 23:58 |
fenn | no science for you! | 23:59 |
