The fountain of youth<b style="box-sizing: border-box;"> </b>legend
goes back to the fifth century BC, appearing in writings by Herodotus,
but not until recently did scientists make a real breakthrough in
reversing aging.</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
The
Stuart Kim Lab of Stanford University School of Medicine has
successfully rejuvenated nematodes. Generally, nematodes live about 20
days. An 18-day-old nematode can hardly move, under normal
circumstances. However, the Stuart Kim Lab has managed to double a
nematode’s life span and make the 40-day-old stay as active as a
10-day-old!</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
“The
key to the nematode’s rejuvenation is ELT-3, a transcription factor
that regulates a large number of downstream genes,” said Dr. Stuart Kim,
professor of the departments of Developmental Biology and Genetics at
Stanford University.</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
Dr.
Kim explained that ELT-3 declines in the nematode with age, and that
subsequently leads to the degeneration of all the cells it regulates.
However, once ELT-3 is artificially enhanced in the lab, all the cells
are recharged, and the nematode regains its youth.</div>

Can
the nematode experience be applied to human beings? According to Dr.
Kim, comparable mechanisms have been found in the human brain, heart,
muscles, and kidneys.</div>

The
discoveries of the so-called “master regulators” in human beings
challenge the traditional view of aging which attributes its cause to
only wear and tear. The new theory of aging, developmental drift, states
that aging happens when master regulators become less functional and
organismal development goes awry.</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
To make the two theories easier to understand, Dr. Kim compares the human body to an automobile.</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
“An
old person doesn’t move very fast, just like an old car,” said Dr. Kim.
“The old theory says the car gets old because its parts are worn out,
but we think there’s more to it. We’ve found master regulators, each of
which can turn on or turn off hundreds of genes.”</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
“In
a car, the master regulator is the gas pedal,” he explained. “In
animals and people, the master regulators are transcription factors and
growth factors. It’s exciting to know these master regulators. Think
about it. With the wear and tear model, we cannot fix all the parts that
have been worn out. But if aging is just the gas pedal not being pushed
down hard enough, you can push it harder. It’s much easier to fix.”</div>Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-4896941529692802109.post-11600552820145095032015-12-21T04:00:00.001-08:002016-01-23T20:50:58.609-08:00For Those With Nut Allergies: Morningstar Farms Recall<br />
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
MorningStar
Farms has issued a “voluntary, precautionary” recall of two varieties
of bean burgers because there may be peanuts in certain lots of them
which are not noted in the products’ ingredient statements, the U.S.
Food and Drug Administration has announced.</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
The varieties are “Spicy Black Bean” and “Chipotle Black Bean.”</div>
<div style="background-color: #fcfcfc; box-sizing: border-box; color: #333333; font-family: 'Open Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 17px; line-height: 28.546875px; margin-bottom: 1.2em;">
No illnesses have been reported to the FDA as of Friday, the federal agency said.</div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
“This
product is safe to consume for individuals who do not suffer from a
peanut allergy,” Stop & Shop supermarkets said in a news release.</div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
But the news release also said:</div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
“People
who have an allergy or severe sensitivity to peanuts may run the risk
of serious or life-threatening allergic reaction if they consume this
product. Symptoms of food allergies typically appear from within a few
minutes to two hours after a person has eaten the food to which he or
she is allergic. Allergic reactions can include: hives; flushed skin or
rash; tingling or itchy sensation in the mouth; face, tongue, or lip
swelling; vomiting and/or diarrhea; abdominal cramps; coughing or
wheezing; dizziness and/or lightheadedness; swelling of the throat and
vocal cords; difficulty breathing; loss of consciousness.”</div>

Some
of the MorningStar Farms products were sold to food-service providers
in addition to retail stores, so consumers who may eat the bean burgers
may not know whether the product was from MorningStar farms, much less
that it was the subject of a recall.</div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
<i style="box-sizing: border-box;">Here’s the FDA’s announcement, released Friday:</i></div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
<i style="box-sizing: border-box;">MorningStar Farms</i> is
issuing a voluntary and precautionary recall of certain code dates of
Spicy Black Bean Burgers and Chipotle Black Bean Burgers because they
may contain undeclared peanut.</div>
<div style="box-sizing: border-box; margin-bottom: 1.2em;">
<i style="box-sizing: border-box;">MorningStar Farms</i> was
notified by a third party supplier that one of the spice ingredients
used in Spicy Black Bean Burgers and Chipotle Black Bean Burgers may
inadvertently contain peanut, an allergen that is not declared on the
products’ ingredient statements. People who have an allergy or severe
sensitivity to peanuts run the risk of serious or life-threatening
allergic reaction if they consume these products.</div>
