Anti-Aging Effect of
Riboflavin Via Endogenous Antioxidant in Fruit fly Drosophila Melanogaster -
J Nutr Health Aging. 2017;21(3):314-31 - "Riboflavin
prolonged the lifespan and increased the reproduction of fruit flies through
anti-oxidative stress pathway involving enhancing the activity of SOD1 and CAT
and inhibiting LF accumulation. Riboflavin deserves more attention for slowing
human aging" - See riboflavin at
High-sugar diet programs a short lifespan in flies - Science Daily, 1/11/17
- "Flies with a history of eating a high sugar diet live
shorter lives, even after their diet improves. This is because the unhealthy
diet drives long-term reprogramming of gene expression ... The FOXO gene is
important for longevity in a wide variety of species, including yeast, flies,
worms and humans, so the team say the findings may have broad implications"
compound reduces signs of aging in healthy mice - Science Daily, 10/27/16 -
"With age, the body loses its capacity to make a key
element of energy production called NAD (nicotinamide adenine dinucleotide) ...
Past research also has shown that NAD is not effective when given directly to
mice so the researchers sought an indirect method to boost its levels. To do so,
they only had to look one step earlier in the NAD supply chain to a compound
called NMN (nicotinamide mononucleotide) ... NMN can be given safely to mice and
is found naturally in a number of foods, including broccoli, cabbage, cucumber,
edamame and avocado. The new study shows that when NMN is dissolved in drinking
water and given to mice, it appears in the bloodstream in less than three
minutes. Importantly, the researchers also found that NMN in the blood is
quickly converted to NAD in multiple tissues ... The researchers found a variety
of beneficial effects of NMN supplementation, including in skeletal muscle,
liver function, bone density, eye function, insulin sensitivity, immune
function, body weight and physical activity levels" - See

Activation of the
AMPK/Sirt1 pathway by a leucine-metformin combination increases insulin
sensitivity in skeletal muscle, and stimulates glucose and lipid metabolism and
increases life span in Caenorhabditis elegans - Metabolism. 2016 Jul 9 -
"We have previously shown leucine (Leu) to activate
Sirt1 by lowering its KM for NAD+, thereby amplifying the effects of other
sirtuin activators and improving insulin sensitivity. Metformin (Met) converges
on this pathway both indirectly (via AMPK) and by direct activation of Sirt1 ...
Leu and Met synergize to enable Sirt1 activation at low NAD+ concentrations
(typical of energy replete states). Sirt1 and AMPK activations are required for
Met-Leu's full action, which result in improvements in energy metabolism and
insulin sensitivity" - See BulkSupplements Pure L-Leucine Powder (1 Kilogram)

Pomegranate finally reveals its powerful anti-aging secret - Science Daily,
7/11/16 - "The team started out by testing their hypothesis on the usual
suspect: the nematode C. elegans. It's a favorite test subject among aging
experts, because after just 8-10 days it's already considered elderly. The
lifespan of worms exposed to urolithin A increased by more than 45% compared
with the control group ...
These initial encouraging results led the team to test the molecule on animals
that have more in common with humans. In the rodent studies, like with C.
elegans, a significant reduction in the number of mitochondria was observed,
indicating that a robust cellular recycling process was taking place. Older
mice, around two years of age, showed 42% better endurance while running than
equally old mice in the control group" - See

Chlorogenic Acid Extends
the Lifespan of Caenorhabditis elegans via Insulin/IGF-1 Signaling Pathway -
J Gerontol A Biol Sci Med Sci. 2016 Jul 4 - "Coffee and
tea, two of the most popular drinks around the world, share many in common from
chemical components to beneficial effects on human health. One of their shared
components, the polyphenols, most notably chlorogenic acid (CGA), was supposed
to account for many of the beneficial effects on ameliorating diseases occurred
accompanying people aging, such as the antioxidant effect and against diabetes
and cardiovascular disease ... We found that CGA could extend the lifespan of C.
elegans by up to 20.1%, delay the age-related decline of body movement, and
improve stress resistance" - See

widespread loss of more than half of their brain cells, severely impacting
multiple regions of the brain by one year of age, the human equivalent of severe
Alzheimer's disease ... they also discovered that the mice on the supplements
experienced enhancement in vision and most remarkably in the sense of smell --
the loss of which is often associated with neurological disease -- improved

stops the aging process of organs - Science Daily, 4/28/16 -
"As mice, like all mammals, age, the regenerative
capacity of certain organs (such as the liver and kidneys) and muscles
(including the heart) diminishes. Their ability to repair them following an
injury is also affected. This leads to many of the disorders typical of aging
... We gave nicotinamide riboside to 2-year-old mice, which is an advanced age
for them ... This substance, which is close to vitamin B3, is a precursor of
NAD+, a molecule that plays a key role in mitochondrial activity. And our
results are extremely promising: muscular regeneration is much better in mice
that received NR, and they lived longer than the mice that didn't get it ...
Parallel studies have revealed a comparable effect on stem cells of the brain
and skin ... So far, no negative side effects have been observed following the
use of NR, even at high doses" - See

Scientific secrets for successful aging? - Science Daily, 3/29/16 -
"Now that these age-related metabolites have been
identified, the decline in antioxidants and muscle strength suggest that it is
important for individuals to consume foods high in antioxidants and to continue
exercising, especially after the age of 65. This could help increase the levels
of the related metabolites in the body and improve body conditions"
cream ingredient found to mimic life-extending effects of a calorie restriction
diet - Science Daily, 12/16/15 - "scientists have shown for the first time
that allantoin, which is found in botanical extracts of the comfrey plant and is
an ingredient of many anti-ageing creams, can mimic the effect of calorie
restriction and increase lifespan in worms by more than 20% ... worms treated
with allantoin, rapamycin, trichostatin A and LY-294002 not only lived longer,
but also stayed healthier longer. Additionally, when the same compounds were
tested in mutant worms they extended lifespan in a way expected from calorie
restriction" - See allantoin products at Amazon.com.
drug protects stem cells from aging - Science Daily, 12/17/15 -
"the drug zoledronate is able to extend the lifespan of
mesenchymal stem cells by reducing DNA damage ... DNA damage is one of the most
important mechanisms of aging where stem cells lose their ability to maintain
and repair the tissues in which they live and keep it working correctly"
acid activates daf-16 to increase lifespan in C.elegans - Biochem Biophys
Res Commun. 2015 Nov 16 - "We investigate here whether OA has an impact on
longevity in vivo, and more specifically, we have examined effects of OA on the
lifespan and stress tolerance in Caenorhabditis elegans (C.elegans). Our results
showed that OA could extend the lifespan, increase its stress resistance and
reduce the intracellular reactive oxygen species (ROS) in wild-type worms.
Moreover, we have found that OA-induced longevity may not be associated with the
calorie restriction (CR) mechanism" - See oleanolic acid at Amazon.com.

"Here, we show for first time that FA extends organism
life span and causes a delay in aging. We observed that FA inhibits mechanistic
target of rapamycin (mTOR) and insulin/insulin growth factor 1 (IGF-1) signaling
pathways to control both oxidative stress levels and life span. The expression
levels of stress- and life span-relevant gerontogenes, viz. daf-16, skn-1, and
sir. 2.1, and oxidative enzymes, such as glutathione S-transferase 4 (GST-4) and
superoxide dismutase 3 (SOD-3), were also found to be highly enhanced to
attenuate the intracellular reactive oxygen species (ROS) damage and to delay
the aging process. Our study promotes the use of FA to mitigate abiotic stresses
and other aging-related ailments" - See

Nutraceutical intervention reverses the negative effects of blood from aged rats
on stem cells - Age (Dordr). 2015 Oct - "Aging is
associated with a decline in function in many of the stem cell niches of the
body. An emerging body of literature suggests that one of the reasons for this
decline in function is due to cell non-autonomous influences on the niche from
the body ... We examined if we could reverse this effect of aged serum on stem
cell proliferation by treating aged rats with NT-020, a dietary supplement
containing blueberry, green tea, vitamin D3, and carnosine that has been shown
to increase neurogenesis in aged rats. Young and aged rats were administered
either control NIH-31 diet or one supplemented with NT-020 for 28 days, and
serum was collected upon euthanasia ... Serum from aged rats significantly
reduced cell proliferation as measured by the
3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and
5-bromo-2'-deoxyuridine (BrdU) assays in both NPCs and MSCs. Serum from aged
rats treated with NT-020 was not different from serum from young rats.
Therefore, NT-020 rescued the effect of serum from aged rats to reduce stem cell
Are You Aging Faster Than Everyone Else? - NBC News, 7/7/15 -
"as early as age 38, some people are biologically much
older. In fact, some look like they're in their 60s, while others still look
like 20-somethings ... Some of the people in our cohort had aged physiologically
not at all between 26 and 38 ... At the other end of the extreme there were
folks aging two to three times as much ... Their scores on the tests looked like
people who are in their 50s and 60s ... The study members who appeared to be
aging faster in their physiologies were also doing less well on the physical
function ... We saw that already by age 38, study members whose physiologies
were aging faster were showing signs of cognitive decline ... Perhaps most
stunning, the aging-related changes showed up in people's faces"
improves putative longevity effectors in peripheral mononuclear cells from
subjects with prediabetes. A randomized controlled trial - Nutr Metab
Cardiovasc Dis. 2015 Mar 24 - "Compared to baseline,
metformin significantly improved metabolic parameters and insulin sensitivity,
increased SIRT1 gene/protein expression and SIRT1 promoter chromatin
accessibility, elevated mTOR gene expression with concomitant reduction in
p70S6K phosphorylation in subjects' PBMCs, and modified the plasma N-glycan
profile. Compared to placebo, metformin increased SIRT1 protein expression and
reduced p70S6K phosphorylation (a proxy of mTOR activity). Plasma N-glycans were
also favourably modified by metformin compared to placebo" - See

trade-offs versus cost-free life extension? - Age (Dordr). 2015
Apr;37(2):9769 - "Both drugs significantly increased
survivorship and maximal life span. Maximal longevity was 136 days for controls,
188 days (138 % of controls) for metformin, and 194 days (143 % of controls) for
aspirin. Metformin and aspirin in combination extended longevity to a lesser
degree (163 days, 120 % of controls)" - See

class of drugs dramatically increases healthy lifespan, mouse study suggests
- Science Daily, 3/9/15 - "like cancer cells, senescent
cells have increased expression of "pro-survival networks" that help them resist
apoptosis or programmed cell death. This finding provided key criteria to search
for potential drug candidates ... Using these criteria, the team homed in on two
available compounds -- the cancer drug dasatinib (sold under the trade name
Sprycel®) and quercetin, a natural compound sold as a supplement that acts as an
antihistamine and anti-inflammatory ... The two compounds had different strong
points. Dasatinib eliminated senescent human fat cell progenitors, while
quercetin was more effective against senescent human endothelial cells and mouse
bone marrow stem cells. A combination of the two was most effective overall ...
In animal models, the compounds improved cardiovascular function and exercise
endurance, reduced osteoporosis and frailty, and extended healthspan" -

soda consumption, cell aging associated in new study - Science Daily,
10/16/14 - "Regular consumption of sugar-sweetened sodas
might influence disease development, not only by straining the body's metabolic
control of sugars, but also through accelerated cellular aging of tissues ...
Based on the way telomere length shortens on average with chronological age, the
UCSF researchers calculated that daily consumption of a 20-ounce soda was
associated with 4.6 years of additional biological aging. This effect on
telomere length is comparable to the effect of smoking, or to the effect of
regular exercise in the opposite, anti-aging direction"
Sense of Smell May Predict Longevity - NYTimes.com, 10/1/14 -
"people who could not detect the odors were more than
three times as likely to die within five years as those who could. The lower
their scores on the odor test, the more likely they were to die. Only severe
liver damage was a better predictor of death ... The researchers believe that
the decline in the ability to smell is an indicator of some other age-related
degeneration, and is not itself a cause of death"
enhances parental reproductive lifespan and progeny viability in Drosophila
melanogaster - Age (Dordr). 2014 Oct;36(5):9702 -
"We have used the well-established model organism, Drosophila melanogaster, and
ascertained the consequence of diet supplementation with curcumin. Flies reared
on curcumin-supplemented diet had significantly higher lifespan. The progeny of
flies reared on curcumin had a higher viability. The activity of a key
mitochondrial enzyme-aconitase was significantly higher in flies reared on
curcumin-supplemented diet. The results suggest that curcumin can not only
correct a key step in the citric acid cycle and help in the release of
additional energy but also permanently correct developmental and morphogenetic
processes" - See

Vitamin D: A Key to a Longer Life? - WebMD, 6/17/14 -
"The researchers examined eight studies from Europe and
the United States that together tracked more than 26,000 nonsmoking men and
women ... Those with the lowest levels of vitamin D were about 1.5 times more
likely than those with the highest levels to die from any cause and from heart
disease during the periods of the studies. Those with low levels of vitamin D
and a history of cancer were 1.7 times more likely to die of the disease ...
It's not clear how vitamin D could help people live longer, but it might have
something to do with the way it acts like a hormone" - See

Concentrations of a Urinary Biomarker of Polyphenol Intake Are Associated
with Decreased Mortality in Older Adults - J Nutr. 2013 Jun 26 -
"Polyphenols might have a role in the prevention of
several chronic diseases, but evaluating total dietary polyphenol (TDP)
intake from self-reported questionnaires is inaccurate and unreliable. A
promising alternative is to use total urinary polyphenol (TUP) concentration
as a proxy measure of intake. The current study evaluated the relationship
between TUPs and TDPs and all-cause mortality during a 12-y period among
older adult participants ... In the multivariable Cox model, participants in
the highest tertile of TUP at enrolment had a lower mortality rate than
those in the lowest tertile [HR = 0.70 (95% CI: 0.49-0.99); P-trend =
0.045], whereas no significant associations were found between TDP and
overall mortality. TUP is an independent risk factor for mortality among
community-dwelling older adults, suggesting that high dietary intake of
polyphenols may be associated with longevity" - See

How diabetes drug delays aging in worms - Science Daily, 3/28/13 -
"Following a calorie-restricted diet has been shown
to improve health in later life and extend lifespan in a number of animals,
ranging from the simple worm to rhesus monkeys. The type 2 diabetes drug
metformin has been found to have similar effects in animals ... Overall,
treatment with metformin adds up to 6 days of life for the worm which is
equivalent to around a third of its normal lifespan. It seems to work by
altering metabolism in the bacteria that live in the worm, which in turn
limits the nutrients that are available to the worm host and has a similar
effect to restricting the diet ... However, when they added an excess of
sugar to the diet, the team found that the life-extending effects of
metformin were cancelled out" - See

Hydrogen sulfide: The next anti-aging agent? - Science Daily, 1/29/13 -
"Hydrogen sulfide* (H2S) may play a wide-ranging
role in staving off aging ... Hydrogen sulfide is produced within the human
body, and has a variety of important physiological effects. For example, it
relaxes the vascular endothelium and smooth muscle cells, which is important
to maintaining clean arteries as one ages ... It functions as an
antioxidant. And it inhibits expression of pro-inflammatory factors, all of
which "imply an important role in aging and age-associated diseases," ...
Produced in the kidneys, it has direct angiotensin-converting enzyme (ACE)
inhibiting activity; that is, it's an ACE inhibitor, just like certain drugs
that mitigate high blood pressure. Not surprisingly, plasma H2S declines
with age, and is lower in spontaneously hypertensive rats than in those with
normal blood pressure. More generally, a lack of H2S is implicated in

Regular jogging shows dramatic increase in life expectancy - Science
Daily, 5/3/12 - "Results show that in the follow-up
period involving a maximum of 35 years, 10,158 deaths were registered among
the non-joggers and 122 deaths among the joggers. Analysis showed that risk
of death was reduced by 44% for male joggers (age-adjusted hazard ratio
0.56) and 44% for female joggers (age-adjusted hazard ratio 0.56) ...
Furthermore the data showed jogging produced an age adjusted survival
benefit of 6.2 years in men and 5.6 years in women. Further analysis
exploring the amounts of exercise undertaken by joggers in the study has
revealed a U-shaped curve for the relationship between the time spent
exercising and mortality. The investigators found that between one hour and
two and a half hours a week, undertaken over two to three sessions,
delivered the optimum benefits, especially when performed at a slow or
average pace ... The ideal pace can be achieved by striving to feel a little
breathless. "You should aim to feel a little breathless, but not very
breathless," ... It improves oxygen uptake, increases insulin sensitivity,
improves lipid profiles (raising HDL and lowering triglycerides), lowers

muscles weaken with age and points to possible therapy - Science Daily,
8/2/11 - "As we grow older, our skeletal muscles
tend to wither and weaken, a phenomenon known as sarcopenia. Sarcopenia,
which begins to appear at around age 40 and accelerates after 75, is a major
cause of disability in the elderly. Exercise can help counter the effects of
age-related muscle loss ... Both the aging process and the genetic defect
responsible for muscular dystrophy cause an increase in the production of
oxygen free radicals, highly reactive and harmful molecules. "Our data
suggest that this sets up a vicious cycle, in which the free radicals cause
ryanodine receptors to leak calcium into the cell. The calcium poisons
mitochondria -- organelles that power the cell -- leading to the release of
even more free radicals. This, in turn, causes more calcium leakage. With
less calcium available for contraction, the muscles get weaker," ... The
study also points to a possible therapy for sarcopenia: an experimental drug
called S107 ... "Most investigators in the field of aging have been saying
that the way to improve muscle strength is to build muscle mass, using such
therapies as testosterone, growth hormone, and insulin-like growth
factor-1," says Dr. Marks. "But an increase in muscle mass is not
necessarily accompanied by an increase in muscle function"

to long life? Not what you might expect - Science Daily, 3/12/11 -
""Don't work too hard, don't stress," doesn't work

and committed to their jobs did the best. Continually productive men and
women lived much longer than their more laid-back comrades ... "One of the
findings that really astounds people, including us, is that the Longevity
Project participants who were the most cheerful and had the best sense of
humor as kids lived shorter lives, on average, than those who were less
cheerful and joking. It was the most prudent and persistent individuals who
stayed healthiest and lived the longest." ... Part of the explanation lies
in health behaviors -- the cheerful, happy-go-lucky kids tended to take more
risks with their health across the years, Friedman noted. While an
optimistic approach can be helpful in a crisis, "we found that as a general
life-orientation, too much of a sense that 'everything will be just fine'
can be dangerous because it can lead one to be careless about things that
are important to health and long life. Prudence and persistence, however,
led to a lot of important benefits for many years"
Can Exercise Keep You Young? - NYTimes.com, 3/2/11 -
"in heartening new research published last week in
The Proceedings of the National Academy of Sciences, exercise reduced or
eliminated almost every detrimental effect of aging in mice that had been
genetically programmed to grow old at an accelerated pace ... mitochondria
can accumulate small genetic mutations, which under normal circumstances are
corrected by specialized repair systems within the cell. Over time, as we
age, the number of mutations begins to outstrip the system’s ability to make
repairs, and mitochondria start malfunctioning and dying ... Half of the
mice were allowed to run on a wheel for 45 minutes three times a week,
beginning at 3 months ... At 8 months, when their sedentary lab mates were
bald, frail and dying, the running rats remained youthful. They had full
pelts of dark fur, no salt-and-pepper shadings. They also had maintained
almost all of their muscle mass and brain volume. Their gonads were normal,
as were their hearts. They could balance on narrow rods, the showoffs ...

"Similar to those effects associated with caloric restriction (CR),
resveratrol has multiple beneficial activities, such as increased life span
and delay in the onset of diseases associated with aging ... Here, we show
that resveratrol activated AMPK in both ER-positive and ER-negative breast
cancer cells ... Here, we show that resveratrol activated AMPK in both
ER-positive and ER-negative breast cancer cells. Once activated, AMPK
inhibited 4E-BP1 signaling and mRNA translation via mammalian target of
rapamycin (mTOR). Moreover, we also found that AMPK activity mediated by
resveratrol in cancer cells was due to inducing the expression of Sirtuin
type 1 (SIRT1) via elevation in the cellular NAD(+)/NADH in ER-positive
cells. To our knowledge, we demonstrate here for the first time that
resveratrol induces the expression of SIRT1 protein in human cancer cells.
These observations raise the possibility that SIRT1 functions as a novel
upstream regulator for AMPK signaling and may additionally modulate tumor
cell proliferation. Targeting SIRT1/AMPK signaling by resveratrol may have
potential therapeutic implications for cancer and age-related diseases"

"Loss of cardiomyocytes through apoptosis has been proposed as a cause of
ventricular remodeling and heart failure. Ischemia- and hypoxia-induced
apoptosis of cardiomyocytes reportedly plays an important role in many
cardiac pathologies. We investigated whether resveratrol (Res) has direct
cytoprotective effects against ischemia/hypoxia for cardiomyocytes. Exposure
of H9c2 embryonic rat heart-derived cells to hypoxia for 24h caused a
significant increase in apoptosis, as evaluated by TUNEL and flow cytometry,
while treatment with 20muM Res greatly decreased hypoxia-induced apoptosis
in these cells. Exposure of the cells to Res (20muM) caused rapid activation
of SIRT1, which had a dual effect on FoxO1 function: SIRT1 increased FoxO1's
ability to induce cell cycle arrest, but inhibited FoxO1's ability to induce
cell death. This effect could be reversed by SIRT1 inhibition. Results of
our study indicate that Res inhibits hypoxia-induced apoptosis via the

Melatonin: The Fountain Of Youth? - Science Daily, 6/22/09 -
"Melatonin can slow down the effects of aging. A team at
laboratoire Arago in Banyuls sur Mer (CNRS / Université Pierre et Marie Curie)
has found that a treatment based on melatonin can delay the first signs of aging
in a small mammal ... studied the long-term effects of melatonin on the Greater
White-toothed shrew, a small nocturnal insectivorous mammal. Under normal
conditions, this animal shows the first signs of aging after reaching 12 months,
mainly through the loss of circadian rhythm in its activities. By continuously
administering melatonin, starting a little before 12 months, the appearance of
these first signs was delayed by at least 3 months, which is a considerable
period in relation to the lifespan of this shrew ... Melatonin is now known to
play several beneficial roles. These include being an antioxidant, an
anti-depressant, and helping to remediate sleep problems" - See

Multivitamins linked to younger ‘biological age’: Study - Nutra USA, 5/27/09
- "Compared to non-multivitamin users, the researchers
noted that that telomeres were on average 5.1 per cent longer for daily
multivitamin users ... Whereas the evidence is not sufficient to conclude that
these 2 dietary antioxidants mediated the observed relation, the results are
consistent with experimental findings that vitamins C and E protect telomeres in
vitro" - [Abstract]
Multivitamin use and telomere length in women - Am J Clin Nutr. 2009
Jun;89(6):1857-63 - "After age and other potential
confounders were adjusted for, multivitamin use was associated with longer
telomeres. Compared with nonusers, the relative telomere length of leukocyte DNA
was on average 5.1% longer among daily multivitamin users (P for trend = 0.002).
In the analysis of micronutrients, higher intakes of vitamins C and E from foods
were each associated with longer telomeres, even after adjustment for
multivitamin use. Furthermore, intakes of both nutrients were associated with
telomere length among women who did not take multivitamins"

Sweet: Over-consumption Of Sugar Linked To Aging - Science Daily, 3/9/09 -
"We know that lifespan can be extended in animals by
restricting calories such as sugar intake ...it's not sugar itself that is
important in this process but the ability of cells to sense its presence ... the
lifespan of yeast cells increased when glucose was decreased from their diet.
They then asked whether the increase in lifespan was due to cells decreasing
their ability to produce energy or to the decrease in signal to the cells by the
glucose sensor ... cells unable to consume glucose as energy source are still
sensitive to the pro-aging effects of glucose. Conversely, obliterating the
sensor that measures the levels of glucose significantly increased lifespan"
Aging: Anti-aging Pathway Enhances Cell Stress Response - Science Daily,
2/19/09 - "The researchers discovered a new molecular
relationship critical to keeping cells healthy across a long span of time: a
protein called SIRT1, important for caloric restriction and lifespan and
activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it
active. HSF1 in turn senses the presence of damaged proteins in the cell and
elevates the expression of molecular chaperones to keep a cell's proteins in a
folded, functional state. Regulation of this pathway has a direct beneficial
effect to cells ... decrease in SIRT1 may help explain why protein misfolding
diseases, such as Alzheimer's, Parkinson's, Huntington's and adult-onset
diabetes, are diseases of aging" - See

Gastrointestinal Drug Slows Aging, Researchers Say - Science Daily, 1/6/08 -
"Recent animal studies have shown that clioquinol – an
80-year old drug once used to treat diarrhea and other gastrointestinal
disorders – can reverse the progression of Alzheimer's, Parkinson's and
Huntington's diseases ... clioquinol acts directly on a protein called CLK-1,
often informally called "clock-1," and might slow down the aging process ...
Because clock-1 affects longevity in invertebrates and mice, and because we're
talking about three age-dependent neurodegenerative diseases, we hypothesize
that clioquinol affects them by slowing down the rate of aging ... clioquinol
was withdrawn from the market after being blamed for a devastating outbreak of
subacute myelo-optic neuropathy (SMON) in Japan in the 1960s. However, because
no rigorous scientific study was conducted at the time, and because clioquinol
was used safely by millions before and after the Japanese outbreak, some
researchers think its connection to SMON has yet to be proven" - I

Major Theories About Human Cellular Aging Supported By New Research -
Science Daily, 12/30/08 - "old age is the final stage of
a developmental program AND the result of a lifelong accumulation of unrepaired
cellular and molecular damage ... When fatty acids build up, yeast cells explode
from within, scattering their contents and spreading inflammation to neighboring
cells ... In addition to cell death, the accumulation of fatty acids sets off
chemical reactions that ultimately produce a lipid called diacylglycerol, which
impairs many of the yeast's stress response-related defenses ... Low-calorie
diets, which have been shown to increase lifespan and delay age-related
disorders in nonhuman primates and other organisms, altered the way fats were
processed in the yeast cells"
a Possible Cause of Aging - NYTimes.com, 11/26/08 -
"A new insight into the reason for aging has been gained by scientists trying to
understand how resveratrol, a minor ingredient of red wine, improves the health
and lifespan of laboratory mice. They believe that the integrity of chromosomes
is compromised as people age, and that resveratrol works by activating a protein
known as sirtuin that restores the chromosomes to health ... Dr. Sinclair has
been taking large daily doses of resveratrol since he and others discovered five
years ago that it activated sirtuin. “I’m still taking it and I feel great,” he
said, “but it’s too early to say if I’m young for my age."" - See

- Warning Against
'Anti-Aging' Medicine - WebMD, 3/6/02 - Articles like this burn me up.
Most people will be six feet under before those studies come in. I feel you
need to go with the best scientific information available at the time. Also,
Dr. Smith’s comment that "There is as yet no convincing evidence that
administration of any specific compound, natural or artificial, can globally
slow aging in people, or even in mice or rats" is absolutely false. Take for
example the study published in the 2/19/02 Proceedings of the National
Academy of Sciences on alpha lipoic acid and acetyl-l-carnitine or the
studies with deprenyl and rats? I could go on and on. Some doctors think
that the three credits in nutrition they got back in 1985 from text books
written in the 70’s allow them to make bold lies without even reading the
research. LEF has references for their articles. I guess if your a doctor,
you can make bold statements like Dr. Smith's without references. I agree
with the following statement by Dr. Klatz: "To become a physician, you have
to take the Hippocratic Oath, in which you swear to "do no harm." But there
are many ways to interpret that phrase. As all Catholics are aware, there
are sins of omission and sins of commission. Cutting off the wrong leg of a
diabetic or operating on the wrong side of the head in a patient with a
brain tumor as happened recently in two New York hospitals is clearly doing
harm. But what about not keeping abreast of the latest diagnostic treatment
or advances? Or failing to inform a patient of lifestyle changes or options
that could drastically lower risk of disease? Or taking a authoritarian,
I-know-better-than-you attitude that effectively cuts off all questions
