St. Paul, MN. June 1, 2004 - For hundreds of years man has
been in search of the Fountain of Youth; a magical potion that can
maintain one’s youth indefinitely. Yet, still today facial wrinkles are
the markings of a person in the later years of their life.
More and more people are turning to anti-wrinkle creams to
substitute for the Fountain of Youth. Many anti-wrinkle creams claim to
smoothen out the skin. What people do not realize is that most of these
creams use AHAs (alpha hydroxy acids), also known as fruit acids. These
chemicals work by peeling off the outer layer of the skin to reveal the
skin beneath.
However, most dermatologists are concerned that AHAs could
in fact cause long-term damage instead of rejuvenating the skin. The
European Commission is so concerned about these AHA’s that it is
considering placing warning labels on all creams containing these
chemicals.
A clinically proven compound to remove wrinkles without
harmful side effects is Acetyl Hexapeptide (Argireline). This peptide is a
powerful non toxic ingredient that can dramatically reduce fine lines and
wrinkles around the eyes, mouth, and forehead.
Argireline reduces the amount of nerve stimulation to the
facial muscles, thus causing the area to smoothen and lessen the
appearance of wrinkles. Nur76 Serum (the latest serum in anti-aging
development) is one of the few anti-aging products that contains the
Argireline.
This compound not only prevents the effects of aging of
skin, but also has been clinically proven to remove existing lines and
wrinkles, particularly in the forehead and eye area. ”Argireline not only
reverses the aging process, but is also known to prevent further aging of
the skin.
In today’s youth oriented culture a younger appearance has
greater status. Cosmetic surgery and injections are glorified in the media
everyday, without mentioning the cost and health risks. Nur76 Serum can
help give you that extra youthful glow, that smoother skin, without costly
and dangerous surgery or paralyzing injections of what is essentially
botulism toxin.”
“The inventors presented several scientific studies to the
Life Extension staff and showed stunning before-and-after photographs
demonstrating this liquid’s efficacy. Finally, it seemed, there was a
topical liquid that produced many of the effects of injections without the
pain and huge expense.”
“For the first time, a patent-pending delivery system has
been developed that enables very large molecules (such as collagen) to
pass through the upper layer of skin. When this new trans dermal system is
combined with collagen, the collagen molecules are delivered directly to
the third layer of the epidermis—an effect achieved previously only by
injection.”

Jan. 17 issue - Though death is still as inevitable as
taxes, future generations may age more slowly and live significantly
longer. Here are five scientists in the vanguard of research, offering new
insights into the biochemistry of aging—and opening the door for
life-lengthening drugs. Their approaches vary, but they share the belief
that the human life span is not fixed.
Enhanced:TARGETED GENES ARE MORE ACTIVE IN FIGHTING
AGING
The "guess your age" booth at a carnival isn't often exactly
right. But it's not usually as off-base as Cynthia Kenyon's colleagues. A
few years ago Kenyon, a molecular geneticist, had one of her grad students
cart a tray of worms around her lab, asking people how old they thought
the worms were. Most said about 5 days. What they didn't know was that
Kenyon had tinkered with the worms' genes. The squirmy creatures had the
perfect health of 5-day-olds, but they were 144 days old—six times their
normal life span.
Over the last decade, Kenyon's continuing work has shown
that "you can make huge changes in life span so easily"—in worms, at
least—by changing hormone levels and enhancing the effects of fewer than
100 genes. Some of the target genes produce antioxidants; some make
natural microbicides; some are involved in transporting fats throughout
the body, and some, called chaperones, "keep the cell components in good
working order," says Kenyon. What they all have in common is their effect
on aging. The more active the genes, in general, the longer an organism is
likely to live.
When Kenyon's work with worm genes was first published in
1993, skeptics predicted it wouldn't translate well to humans. One hundred
forty-four days might be ancient for a worm, but a far more complex human
being can already expect to live about 200 times longer than that.
Scientists still don't know exactly why the life spans are so different,
much less what a change in a worm's life span might mean for a person's.
Nonetheless, much of the cellular machinery in worms closely resembles
that in higher mammals. That finding has opened the door for a
neutraceutical company, Elixir, which is trying to
develop a drug that would yield the same kind of results as Kenyon's
genetic tampering. "I'm not saying that with a few changes humans could be
immortal," she says. "But it'd be like looking at an 80-year-old and
thinking he was 40." Who could object to that?
Stressed:CHRONIC TENSION MAKES CELLS DETERIORATE
FASTER
If you've ever blamed stress for new wrinkles or gray hairs,
you may have been right. "As a society, we have a deeply held belief that
life stress causes premature aging, but there's actually been very little
empirical evidence to show this," says Elisa Epel, assist-ant professor of
psychiatry at the University of California, San Francisco.
Until now. In a UCSF-led study published this past fall in
Proceedings of the National Academy of Sciences, Epel and her colleagues
found that chronic stress—or even the perception of stress—significantly
shortened the length of telomeres, the tips of chromosomes within cells
that can be used as a measure of the cells' aging process. The shorter the
telomere, the shorter the cell's life span and the faster the body's
deterioration. As more cells die, the effects of aging kick in: muscles
weaken, skin wrinkles and eyesight and hearing worsen.
Epel and her colleagues studied 39 women between the ages of
20 and 50 with children suffering from serious chronic conditions, like
cerebral palsy, and compared them with 19 mothers in the same age group
with healthy children. The longer a woman had been caring for a sick
child, the shorter her telomeres—and the greater her oxidative stress (a
process that releases DNA-damaging free radicals).
But what startled researchers more was that the most
profound differences were tied to the women's perceptions of how much
emotional strain they were under, regardless of whether their children
were healthy or sick. When compared with the women with the lowest
perceived stress levels, women in both groups who described themselves as
having the highest stress levels had telomeres equivalent to someone 10
years older.
While Epel acknowledges that more studies need to be done to
confirm her findings, she says the results could have positive
implications. "Now that we think we can see intracellular damage from
stress, people might weigh the importance of positive mental health more
heavily," she says, adding that there is "absolutely" hope that the DNA
damage is reversible. "Lifestyle changes—and learning to cope well with
stress—could potentially improve your quality of life, your mood and your
longevity.
"Restricted:A TOUGH LIMIT ON CALORIE INTAKE MAY SLOW
AGING
Leonard Guarente didn't come up with the trick of calorie
restriction, or strictly limiting nutrients to achieve longer life. And
the idea sounded crazy back in 1986, when Guarente first proposed to study
the biology of aging via calorie restriction. Aging was seen as too
complex a topic for molecular biologists, and the effect of calorie
restriction on aging, though detailed in scientific literature since the
1930s, was even more poorly understood. Guarente's colleagues called him
"bonkers," but he didn't care: "I wanted to work on something risky," he
says. "Besides, I had just gotten tenure, and at that point they couldn't
get rid of me. "They certainly wouldn't want to now. Guarente is not the
least bit bonkers—and, unbeknown to his colleagues at the time, he wasn't
even the only scientist thinking about the molecular biology of calorie
restriction. In the last decade, researchers have made great strides in
understanding why a sudden drop in calorie intake can kick up the activity
of a gene called SIR2 and prolong life in simple organisms.
At the head of the class are Guarente and a Harvard
researcher named David Sinclair, both of whom are focusing on sirtuins,
the family of proteins produced by SIR2 or its mammalian analogue, SIRT1.
Guarente's lab has unraveled many of the basic molecular processes behind
SIR2. For instance, a natural chemical called NADH can inhibit sirtuins'
effects; Guarente's lab has determined that yeast with lower NADH levels
lives longer. Sinclair's work has a slightly different focus—resveratrol,
the chemical he has connected to calorie restriction's effects. (It's
better known as the major reason red wine is touted as healthful.)
Sinclair's work at Harvard has shown that heavy doses of resveratrol can
prolong life span in yeast by 70 percent. Still another scientist, Marc
Tatar, has garnered similar results in fruit flies.
The fact that calorie restriction works isn't all that
surprising from an evolutionary point of view. In fact, calorie
restriction is an extremely effective strategy for survival during lean
times, when it's an imperative, not a choice. "Let's imagine I had a gene
that could allow me to suspend reproduction and slow down aging during a
famine," says Guarente. "When the famine ends, I'll still be around to
reproduce." As a result, he adds, "every animal we know can do this."
Including humans, of course. But since few people
particularly want to limit their calories drastically (least of all
Americans), Guarente is searching for a pill that will have the same
effect. Elixir, the same company building on Kenyon's work, is also using
Guarente's—which means, someday, humans may reap the benefits of calorie
restriction without even having to say the word diet. Sinclair has a
competing company called Sirtris. He expects to get his drugs into clinics
in just five years. Until then, he'll be drinking one glass of red wine a
day—and toasting to what he hopes will be a huge success.
Supplemented:TWO CHEMICALS MADE OLD RATS
NEW
Five years ago Bruce Ames called his son, a computer
executive in New York, with some exciting news. "I told him, 'We're
changing old rats to new rats!' " recalls Ames, a senior scientist at
Children's Hospital Oakland Research Institute in California. His son was
not impressed. "Let me know when you change old people to young rats," he
said. Such human-to-animal transformations are still confined to the minds
of sarcastic sons and science-fiction writers, but researchers are getting
closer to replicating Ames's rat results in humans.
In studies published in Proceedings of the National Academy
of Sciences in 2002, Ames and his colleagues fed older rats two chemicals
normally found in the body's cells (and also sold as nutritional
supplements): acetyl-L-carnitine and alphalipoic acid. Not only did the
rats perform better on problem-solving and memory tests, but they moved
around with more ease and energy.
Researchers determined that the combination of chemicals had
improved the function of mitochondria, organelles that serve as a cell's
main energy source. Ames formed a company called Juvenon to license the
combination of cell-rejuvenating supplements (also sold separately at
several health stores). The company plans to begin human trials soon to
evaluate the cognitive effects of the dual supplements. In the meantime,
Ames, who chairs Juvenon's scientific advisory board but gets no proceeds
from the company, is overseeing lab research on human cells in tissue
culture. In one study, Berkeley researchers found that lipoic acid
protected the cell from oxidation when iron or hydrogen peroxide was
added.
Now he hopes to replicate those results in human subjects.
Other studies have already linked unhealthy mitochondria to Alzheimer's,
Parkinson's, type 2 diabetes and other degenerative diseases, so reversing
or repairing decay in mitochondria could help to stave off the age-related
diseases. "I'm hoping we can add a few years to people's lives," says
Ames, who's 76. "I think we can."
NewsweekJan. 17 issue - VIENNA, VA.: I've been very
overweight for eight years; before that, I was a normal size. Is it
possible at 60 to get back to my old self—or is that a dream?
DR.
HOWARD LEWINE: No, it is not a dream to get fit and trim at 60. But it
probably won't be easy to get there. Assuming that you are otherwise quite
healthy, I recommend exercise as your first priority. If you have been
very sedentary, then you want to check with your doctor before starting a
physically vigorous program. Once you are medically clear, start with
about 10 minutes to 15 minutes of slow-paced exercise, like walking or
water aerobics, once or twice daily. Work up to a faster heart rate. As
exercise becomes a regular part of your daily routine, start cutting
calories. This is not a diet—it is eating less each day until your caloric
intake becomes less than your daily energy expenditure. Weight loss will
follow.
LOUISVILLE, KY.: Is there any way to avoid having your voice
age? Even on the telephone, the voice is a dead giveaway that a person is
old. Why?
As we age, the cartilage support for the vocal cords becomes
stiffer, decreasing mobility of the cords. The vocal cords and the muscles
of the larynx also lose tone, causing a gap between the vocal cords when
they try to close completely. The age at which this can occur varies.
Although you can't slow down these changes, you can help your voice stay
strong by exercising regularly and avoiding smoking. If you are
persistently hoarse, you might also consider whether stomach-acid reflux
is irritating the vocal cords.
SANDY, UTAH: What is your opinion on
the severe calorie-restriction diet being promoted by some people to slow
the aging process?
We don't have the evidence yet that significant
calorie restriction in humans will extend life or slow aging, but the
studies in animals are quite compelling. Mice that are allowed to eat as
much as they want die much sooner than mice fed a diet with 35 percent
fewer calories daily. Preliminary studies in primates also suggest
healthier aging by eating a calorie-restricted diet. I personally believe
that future research will prove calorie-restriction benefits independent
of weight loss for humans. But those restricting calories need to make
sure that they are getting enough protein and micro nutrients.
