Br J Cancer 2002 May 20;86(10):1615-21 Dietary restriction reduces angiogenesis and growth in an orthotopic mouse brain tumour model. Mukherjee P, El-Abbadi MM, Kasperzyk JL, Ranes MK, Seyfried TN. Biology Department, Boston College, Chestnut Hill, Massachusetts, MA 02467, USA. Diet and lifestyle produce major effects on tumour incidence, prevalence, and natural history. Moderate dietary restriction has long been recognised as a natural therapy that improves health, promotes longevity, and reduces both the incidence and growth of many tumour types. Dietary restriction differs from fasting or starvation by reducing total food and caloric intake without causing nutritional deficiencies. No prior studies have evaluated the responsiveness of malignant brain cancer to dietary restriction. We found that a moderate dietary restriction of 30-40% significantly inhibited the intracerebral growth of the CT-2A syngeneic malignant mouse astrocytoma by almost 80%. The total dietary intake for the ad libitum control group (n=9) and the dietary restriction experimental group (n=10) was about 20 and 13 Kcal day(-1), respectively. Overall health and vitality was better in the dietary restriction-fed mice than in the ad libitum-fed mice. Tumour microvessel density (Factor VIII immunostaining) was two-fold less in the dietary restriction mice than in the ad libitum mice, whereas the tumour apoptotic index (TUNEL assay) was three-fold greater in the dietary restriction mice than in the ad libitum mice. CT-2A tumour cell- induced vascularity was also less in the dietary restriction mice than in the ad libitum mice in the in vivo Matrigel plug assay. These findings indicate that dietary restriction inhibited CT-2A growth by reducing angiogenesis and by enhancing apoptosis. Dietary restriction may shift the tumour microenvironment from a proangiogenic to an antiangiogenic state through multiple effects on the tumour cells and the tumour-associated host cells. Our data suggest that moderate dietary restriction may be an effective antiangiogenic therapy for recurrent malignant brain cancers.

there are a lot of 'loose-ends' in what, i agree, is a general approach that needs to be explored. the first thing that needs to be kept in mind is that simple calorie-restriction doesn't prolong Life [Africa, North Korea], so, perhaps what's happening is that calorie-reduction induces an organism to range-more-widely with respect to what it will accept as 'food', and that it's such wide-ranging-ness that results in bringing micronutrients into a system that would've, otherwise, taken-the-easy-route with respect to 'food'... just eat what's there-in-abundance, missing the micronutrients that're not-there, within the abundance. lab subjects, for instance, might ingest wood-shavings stuff, for instance, and there might be something in-there that is what makes the difference. i'm not saying that the ingestion of wood-shafvings stuff =is= what's happening. i just wanted to point out all the loose-ends stuff that needs to be controlled. for instance, it's a virtual certainty that humans who choose to 'restrict' calorie intake do not just restrict calorie intake. they simultaneously choose better foods, containing a wider range of nutrients. anyway, Cheers, Ian, ken [k. p. collins] Ian Goddard wrote in message <3d1c1782.25504536@news.erols.com>... > >Br J Cancer 2002 May 20;86(10):1615-21 > >Dietary restriction reduces angiogenesis and growth in an >orthotopic mouse brain tumour model. > >Mukherjee P, El-Abbadi MM, Kasperzyk JL, Ranes MK, Seyfried TN. > >Biology Department, Boston College, Chestnut Hill, Massachusetts, >MA 02467, USA. > >Diet and lifestyle produce major effects on tumour incidence, >prevalence, and natural history.

Furthermore, the diets of some of the peoples in the regions that you mention are additionally restricted in many of the essential nutrients such as protein for example. So this confusion does not occur some people practicing calorie restriction call it CRAN (calorie restriction with adequate nutrition) and some even call it CRON (calorie restriction with optimal nutrition). However, I think the last is rather pretentious because no one currently even knows what is optimal nutrition much less is able to achieve it. With respect to calorie restriction, there really are no "loose ends". > so, perhaps > what's happening is that calorie-reduction induces an organism to > range-more-widely with respect to what it will accept as 'food', and that > it's such wide-ranging-ness that results in bringing micronutrients into a > system that would've, otherwise, taken-the-easy-route with respect to > 'food'... just eat what's there-in-abundance, missing the micronutrients > that're not-there, within the abundance.

Not all of them, but they mainly do so in order to *maintain* their intake of all nutrients *except* calories.

admitting that i should've quoted what was said in the original post, which is what you said in your reply to my post, i stand on what i've posted. i've yet to see any experiment design that cannot be improved. it could be that something like the requirement for minimal-feeding has the 'inadvertant' effect of diminishing contamination relative to the all-you-can-eat subjects' food-in-abundance that just sits-there, absorbing air-born pathogens, chemo and decay factors, etc. in the lab. anyone can sense this possibility by just taking a wiff of the air in an animal lab. supplying minimal food, always from a relatively-fresh supply, =might= have an impact. it could be that there're nutrients in the food, which in small concentrations, is 'good', but in larger concentrations, is 'bad'. there're many such substances. it could be that the minimal-feeding just 'hits the mark' with respect to such substances. and it's a =certainty= that the relative-ease of being in an all-you-can-eat environment results in an artificially-imposed TD E/I-minimization 'state', and that this 'reverberates' throughout correlated nervous systems, impacting all manner of neurally-mediated processes. artificially-imposed relative-ease 'dulls' everything else, including immune-system function [which, itself constitutes a nervous-system-mediated form of 'cognition']. could be that the all-you-can-eat rats just die from 'boredom'. it goes =on-and-on= like this. be-cause of any individual nervous system's inherent tight-integration, =every= such problem is tightly-coupled to everything else that's going-on in-there. there're loose-ends aplenty. it's the essence of Science to eliminate them, in all experiments [this, too, is 'just' TD E/I-minimization].

Please learn to respond "inline". That method is preferable because one can clearly see to what each of your responses is related, and is it also less possible for you to skip past some part of the previous response without addressing important points. Sometimes this may be unintentional and innocent, but often it is deceitfully used as means of "escaping" a point that cannot effectively be answered. Kenneth Collins wrote: > admitting that i should've quoted what was said in the original post, which > is what you said in your reply to my post, i stand on what i've posted. > > i've yet to see any experiment design that cannot be improved.

These are excellent points and are all possible. Whether some of them have been looked at I don't know. Perhaps Michael Rae who is much more thoroughly familiar with CR research could answer that question. However, the CR animals have multiple mechanistic differences with the ad lib fed controls (of controls are *not* ad lib fed but are on 10% restriction just so that over-feeding is not a factor) which could all contribute to the longevity effect. Furthermore, recent studies have shown that a gene expression change takes place very quickly after CR is begun, long before some of the processes which you have mentioned above would be likely to have an effect. > it goes =on-and-on= like this. > > because of any individual nervous system's inherent tight-integration, > =every= such problem is tightly-coupled to everything else that's going-on > in-there. Again, I agree. Unfortunately it is not possible to do fully "placebo" CR. Still the effect has been so robust that it is unlikely, IMO, that any major extraneous factors are the reason for its existence. > there're loose-ends aplenty. From my reading, I don't agree. There are very few of any likely significance, IMO. The major one, IMO, is the fact that all animals tested so far have rather short lifespans and the mechanisms of the effect may already be so much more optimized in a longer lived species such as humans, that CR will not accomplish much additional longevity, even though it will still be a highly beneficial anti-morbidity/mortality agent (ie. it will likely extend the years of robust health of those practicing it except for the ones who would have lived to a very old age anyway). > it's the essence of Science to eliminate them, in all experiments [this, > too, is 'just' TD E/I-minimization].

However, as an ex-math professor I take exception to your use of the word "topologically". Topological refers purely to connectedness and all that can be said of humans is that they are topologically equivalent to three wholled donuts.

Again to me, it is not clear what you mean by the above. Are you saying that you think there is still plenty of longevity yet to be accomplished by life style changes currently available? And that is why you do not personally want to push for more (high tech) methods to become available? --Tom Matthews MoreLife for the rational - http://morelife.org Reality based tools for More Life in quantity & quality

[of course, "garbage in, garbage out" applies. the data that're operated-upon within the Calculus must, itself, accurately reflect physical reality. this's the 'point' at which traditional applications of the Calculus have broken-down... erroneous assumptions force the data to diverge from WDB2T, so the Calculus cannot co-incide with WDB2T, and yield, commensurately-inaccurate 'results'. > >to the degree that it diverges from such, relative to physical reality, the >interface-facilitation Maths is 'just' an arbitrary descriptive 'language' >that has usefulness to the degree that both the 'language' and its >correlated experience are simultaneously shared'. > >Big-Difference. > >Maths applied to physical reality can be Verified through its coincidence >with WDB2T. and mis-takes in 'organizing' data operated-upon via this or that Maths can be Recognized in their correlated divergence from WDB2T. which is what Information Calculus [AoK, Ap6] does [or, at least, =can= do. whether or not it does depends upon the scope of the data operated upon within the Information Calculus technique. [i. e., artificially-delimited data [from within artificially-'narrow' 'boundaries'] yield divergent 'solutions.], which is what's discussed in AoK, Ap7. raising the "volitional diminishing-returns decision" threshold corresponds to a 'broadening' of the data that're operated-upon via Information Calculus. [all of AoK can be read as a strictly-Maths paper [in a way analogous to this example]]. k. p. collins > >this's Tapered Harmony's position 'in a nutshell'. > >this's =all= of Science. > >using the WDB2T approach requires 'back-tracking' within 'traditional' >approaches to physical reality, fixing Errors, and rewriting, but, then, >allows progress that was, formerly.

I realise that you take any kind of criticism of your posts as evidence of a government or other conspiracy against you revealing the true nature of reality and the self but I would like to know if you have any evidence at all for your ideas. You seem to broadly put every aspect of human behviour under the scope of "TD E/I minimization" without actually explaining what that is (properly explaining, your oft used definition does not actually make sense e.g. relative ratios (what other type is there?)). At the limit of minimizing excitation, surely there would be no activity at all? what happens then? how is "topologically distributed" any different from just "distributed"? Furthermore, your affected writing style (hyphenating (e.g. be-cause, you are not the first to realise how some words are derived), capitalising mid-sentence and enclosing every other word in apostrophies) is rather grating, as is your melodramatic tone:- you may well recieve more replies if you wrote like everyone else.
