Japan needs to avoid Russia's mistake on Chernobyl

Japan's already reeling economy could be crushed by over-reaction to
the Fukushima disaster, warns radiation scientist T.D. Luckey in the
summer 2011 issue of the Journal of American Physicians and Surgeons.

Japan should not repeat the mistake that Russia made in the tremendous
unwarranted expense of its reaction to Chernobyl. As Mikhail Gorbachev
understood too late, "The nuclear meltdown at Chernobyl 20 years
ago...was perhaps the real cause of the collapse of the Soviet Union
five years later."

Japan should not act on the false presumption, shared by most of the
world's press, that all radiation is harmful, Luckey states. Although
high-dose radiation is clearly lethal, and excess doses (>200 mSv over
an extremely short time, as from the atomic bomb blasts) can induce
cancer, thousands of scientific papers show actual benefits from low
doses, including the prevention of cancer and birth defects.

"We live with chronic radiation deficiency," Luckey believes. The
worldwide background dose of about 3 mSv per year is much less than
the optimum dose of around 100 mSv per year; this is 100 times lower
than the dose that divides healthful from harmful effects of excess
radiation.

Chronic exposure of around 50 mSv per year for two decades in
accidentally contaminated apartments in Taiwan was associated with
only 3.5 cancer deaths per 1,000, compared with the 116 per 1,000
"normally" expected.

Cancer mortality in 7,430 survivors of Hiroshima and Nagasaki who
received between 10 and 19 mSv was significantly lower than that of
controls.

At Fukushima there have been no cases of radiation sickness, and no
deaths from radiation exposure. The feared cancer deaths are all
theoretical ones, predicted for years in the future. Based on past
experience, there will probably be fewer cancer deaths than "normal,"
Luckey concludes.

Japan should not imitate Russia in squandering billions of dollars to
"protect" people from radiation that is actually beneficial. It should
instead base its response on sound scientific data rather than
unjustified fear.

Hmm, we live in a radiation deficiency ... Hope this includes the hot
plutonium particles and internal radiation exposure from strontium
deposited in the bones. And hope the authors have also considered
other effects on the nervous and cardiovascular systems in addition to
the cancer rates. Then we should go shopping for the Fukushima
vegetables, fruits, meat and seafood before it's sold out! Maybe
TEPCO can turn the nuclear hell into a new age regenerative spa
resort ...

But I rather see this "chronic radiation deficiency" claim dangerously
resembling the "essential fatty acid deficiency" claims.

I'm not sure what "effects" you have in mind. The hazardous effects of
radiation are:

1) Radiation sickness, which only appears when the subject has been
exposed to relatively high doses of radiation (> 1 sievert) in a fairly
short time frame.

2) Increased cancer rates

3) Genetic effects

It has been known for a long time that animals do not display the lowest
rates of cancer when they receive no radiation. Cancer rates decline up
to a certain dose rate and then start increasing again when the dose
rate is increased beyond this. Some believe that this is due to hormesis.

This is consistent with the fact that in Colorado and Wyoming, where
background radiation is about twice as high as in most states, cancer
rates are lower than average.

Yes, this is for the natural radon or other external radiation the
source of which is not part of the body. Also depends on the genetic
makeup and other susceptibility factors like the age, lifestyle or the
n-6/n-3 ratio in tissues. But with the nuclear plant accidents we are
talking about the buildup of strontium in bones (affecting bone
marrow), cesium in muscles (affecting the hearth and arteries) or
plutonium hot particles in the lungs. I would rather prefer using
exercise than radiation to induce hormesis if Tepco gave me a
choice ...

Miso Soup: Powerful Antidote to Radiation

The disastrous chain of events precipitated by the 9.0 magnitude
earthquake and subsequent Tsunami that struck Japan has raised concern
for the possible ramifications of radiation carried across the pacific
on wind currents.

In the aftermath of the largest earthquake in to hit Japan in history,
four of the six nuclear reactors at the Fukushima Daiichi Nuclear
Power Station are still in various stages of meltdown and continue to
deteriorate.

According to the New York Times, even the best case scenario could
mean that radioactive release of steam from the crippled plants could
go on for weeks, months or even years.1

People who eat miso regularly may be up to five times more resistant
to radiation than those who do not eat miso. That is the conclusion of
a team of researchers at Hiroshima University’s atomic bomb radiation
research center.2

Dr. Kazumitsu Watanabe, professor of cancer and radiation research
investigated the radioprotective effect of miso, a fermented soy
product, by testing small intestine cells of lab mice. These cells
absorb nutrients and are particularly sensitive to radiation, which
can easily destroy these cells.

The victims of Hiroshima and Nagasaki experienced severe diarrhea
after the atomic bomb blasts because of the massive destruction of
these cells due to radiation. Even when X-rays at levels lethal to
humans were administered to the mice 60 percent of them survived as
opposed to nine percent of the mice that were not fed miso soup.

Akihiro Ito, head of one of the research teams at Hiroshima
University, found that miso helps eliminate toxins from the body
through stimulation of the circulatory and metabolic systems, which
may possibly make miso useful when undergoing chemotherapy.

A mainstay of Japanese cuisine miso is a living, natural food, rich in
enzymes and beneficial bacteria. Miso is available in a variety of
diverse flavors, each having a distinct taste, color, texture and
aroma. In Japan over 70 percent of the population start the day with a
cup of miso soup instead of coffee. Miso soup has a warming,
healthful and alkalizing effect and can provide an enduring source of
energy and nutrition.

Mellow Miso Soup
Soy of Cooking, John Wiley & Sons, Inc ©Marie Oser 1996
Makes about 3 quarts

(1) sheet of Kombu (sea vegetable)
2 quarts of water
3/4 cup chopped onions (sliced scallions/garnish)
3 cloves garlic, minced
1 large fresh tomato, diced
1/3 cup chopped red or green bell pepper
2 Tbsp. grated fresh gingerroot
2 cups vegetable broth
1 teaspoon granulated garlic
1/2 teaspoon ground ginger
5 oz. Lite silken tofu, cubed
1/3 cup mellow white miso
1/4 cup barley miso

Place Kombu in water in a 4-quart saucepan and set aside while
preparing the vegetables. (you may also steep overnight) Add the
onion, garlic, tomato and bell pepper. Bring the mixture to a boil and
reduce heat, simmering for 15 minutes. Remove solids with a handled
wire mesh strainer, and holding it over the soup, press them firmly
against the strainer with a large spoon. Discard solids. Add the
vegetable broth, granulated garlic and ground ginger. Cut the tofu
into small cubes and gently add to soup.

Combine both miso varieties in a small bowl with a cup or so of the
broth, adding broth to the miso gradually. Blend together with a small
whisk or fork, until the mixture is creamed. Add miso mixture to the
soup and simmer gently 2 minutes. Do not boil. Serve immediately
topped with sliced scallions.

The radioprotective effect of miso, a fermentation product from soy
bean, was investigated with reference to the survival time, crypt
survival and jejunum crypt length in male B6C3F1 mice. Miso at three
different fermentation stages (early-, medium- and long-term fermented
miso) was mixed in MF diet into biscuits at 10% and was administered
from 1 week before irradiation. Animal survival in the long-term
fermented miso group was significantly prolonged as compared with the
short-term fermented miso and MF cases after 8 Gy of 60Co-gamma-ray
irradiation at a dose rate of 2Gy min(-1). Delay in mortality was
evident in all three miso groups, with significantly increased
survival. At doses of 10 and 12 Gy X-irradiation at a dose rate of 4
Gy min(-1), the treatment with long-term fermented miso significantly
increased crypt survival. Also the protective influence against
irradiation in terms of crypt lengths in the long-term fermented miso
group was significantly greater than in the short-term or medium-term
fermented miso and MF diet groups. Thus, prolonged fermentation
appears to be very important for protection against radiation effects.

Dr. Shunichi Yamashita, Radiation Advisor to Fukushima: "Fukusima Will
Be World-Famous! It's Just Great!"

Dr. Shunichi Yamashita is a professor at Nagasaki University
(molecular medicine and radiation research), who became one of the two
advisors to Fukushima Prefecture in order to "educate" the residents
throughout Fukushima about radiation after the Fukushima I Nuke Plant
accident.

He is still the radiation advisor, though a movement started by irate
Fukushima residents is gathering steam to demand the prefectural
government to remove him from the position. Why are they angry at him
now?

Because he epitomizes the government and government scholars who told
them all along that the radiation from Fukushima I Nuke Plant was at a
totally safe level, there was nothing to worry about, it was all in
your head, foreign news media are lying, eat, drink, play, live as
normal. It turned out to be anything but normal for Fukushima.

Immediately after the accident, he was sent by the government to major
cities in towns in Fukushima to address the concerns of the citizens.
He addressed them by saying radiation was nothing to worry about, it
was all in their heads, Fukushima would be world-famous so they
shouldn't miss this great opportunity, and the residents should stay
put.

Some of his incredible remarks have appeared in the US media,
including this one in Democracy Now (6/10/2011):

He says that mothers, even mothers exposed to 100 millisieverts,
pregnant mothers, will not have any effect, health effect. Remember
the number 100. Compared to that, the Soviet Union required a
mandatory evacuation during Chernobyl at five millisieverts. This
doctor is quoted as saying, “The effects of radiation do not come to
people that are happy and laughing. They come to people that are weak-
spirited, that brood and fret.”
Well, that and so much more.

The reference that the Democracy Now guest made in the program is part
of his hilarious lecture about radiation and its effect on health,
delivered on March 21, 2011 in front of the large, and worried
audience in Fukushima City, 60 kilometers from Fukushima I Nuke Plant,
2 days after he was appointed as the official radiation advisor to
Fukushima Prefecture.

Fukushima City is the same city where Greenpeace detected cobalt-60 on
June 7.

Also recall that March 21 was is one of the days that saw a large
spike in air radiation throughout Kanto and Tohoku region, for reasons
still not disclosed.

From the lecture on March 21 in Fukushima City, toward the end, before
the Q&A session:

The name "Fukushima" will be widely known throughout the world.
Fukushima, Fukushima, Fukushima, everything is Fukushima. This is
great! Fukushima has beaten Hiroshima and Nagasaki. From now on,
Fukushima will become the world number 1 name [when it comes to
radiation/nuclear incident]. A crisis is an opportunity. This is the
biggest opportunity. Hey, Fukushima, you've become famous without any
efforts! [a chuckle from the audience] Why
not take advantage of this opportunity? For what? Recovery.

First off, my sincere condolences for people who died in the
earthquake and tsunami. We need to deal with the loss, and to recover
from this nuclear disaster. I don't know how it [the nuke accident]
will affect the nuclear energy policy of the national government, as
the nuclear energy is the core of the national energy policy. But I
can tell you this; the health effects are minimal. The only thing we
need to keep an eye on is the amount of exposure of plant workers who
are working with a do-or-die resolution. But we don't have to worry
about the health effects of ordinary people.

And yet you are worried. Worried about whom? Women, pregnant women,
and infants. We are responsible for the future generation. So, every
radiation protection safety limit is based on the amount allowable for
babies. Administering potassium iodide, deciding on the evacuation,
they are all based on protecting children. Adults over 20 years old
have very little sensitivity to radiation. Almost zero. That's the
first thing you have to remember. Still, adults are the ones who worry
the most. This is wrong. Especially wrong if you are male. You smoke
and drink, and worry about radiation? Men don't have to worry. All we
need to do is protect women, children, pregnant women and infants. If
the situation deteriorates, pregnant women and children should escape.
Men should stay put and fight for recovery. You [as Fukushima
residents] are the descendants of people who produced the proud Byakko-
Tai. You should have such a resolution.

To tell you the truth, radiation doesn't affect people who are
smiling, but those who are worried. This has clearly been demonstrated
by animal studies. So, drinking may be bad for your health, but happy
drinkers are less affected by radiation, luckily. I'm not advising you
to drink, but laughter will remove your radiation-phobia. But there's
precious little information to scientifically explain the effects of
laughter. So, please ask all your questions. This is not a lecture,
it's a dialog between you and I.

If you understand Japanese, go listen to the audio file. About 43
minutes and 40 seconds into the audio, you can hear him say these
things.

"Byakko-tai" members were boys aged mostly 16 to 17 but as young as 13
who fought to defend their lord's land (today's Aizu in Fukushima
Prefecture) but chose to kill themselves rather than to surrender in
the civil war that ensued after the Meiji revolution that brought down
the Tokugawa Shogun government. Fukushima was on the side of Tokugawa.

Professor Yamashita was telling the Fukushima City residents to be
like them in the battle with radiation.

His "non lecture" preceding the above is full of misrepresentations
and some outright lies. I may translate that later, if I'm not too
disgusted.

So, imagine the Japanese, particularly those in Fukushima Prefecture,
who have been bombarded by the messages like this since March. A
veritable brainwash, and it may be working, despite the effort by
"outsiders" like Greenpeace.

Throughout Japan, mothers continue to accompany their small children
to kindergartens, and fathers are too busy working. Just like in Japan
before March 11, before the nuke accident. They sometimes frown on
mothers and fathers who are considering withdrawing their children
from kindergartens, saying "How they overreact! How silly!"

Treating Acute Radiation Sickness with Mesenchymal Stromal Stem Cells

William R. Prather RPh, MD, Senior VP Corporate Development; Pluristem
Therapeutics, Haifa, Israel
Drug Discovery & Development - June 22, 2011

The recent nuclear crisis in Japan has highlighted the urgent need to
develop products for the treatment of acute radiation sickness (ARS)
and radiation exposure.

Acute radiation sickness (ARS)—also known as radiation poisoning—
occurs after accidental radiologic or nuclear exposure to a high dose
of radiation over a short period of time. The U.S. unit of measurement
for a radiation dose is the rem (roentgen equivalent in man) and most
people in the United.States receive approximately 0.25 rem per year
from normal background radiation. Flying for 12 hours at 39,000 feet
exposes a person to approximately 0.006 rem, while a mammogram exposes
patients to approximately 0.3 rem.

The onset and types of symptoms that are caused by radiation depend on
the amount of the radiation exposure. At 5 to 10 rem, changes in blood
chemistries occur, while gastrointestinal symptoms begin at
approximately 50 rem. Half of the people exposed to 500 rem will die
within 30 days. The annual dose limit for workers at nuclear plants in
the United States is 5 rem.1

Depending on the level of exposure, bone marrow aplasia may be
combined with gastrointestinal (GI) involvement, cutaneous burns,
muscle radiolysis, lung injury, and/or central nervous system failure,
among other conditions.2 The prodromal phase consists of GI symptoms
that include abdominal pain, nausea, vomiting, and diarrhea lasting an
average of five days. During the latent phase, which occurs over the
ensuing several days, the patient appears to be recovering. However,
over the next several days to weeks, patients suffer a hematopoietic
crisis from the depletion of erythropoietic, thrombocytopoietic, and
leukopoietic precursors within the bone marrow. The illness phase is
characterized by immunosuppression and multiple organ failure with
death occurring within months following the initial exposure, usually
from infection. Hematological malignancies, such as leukemia, can also
occur years after exposure.3

Damage to the whole organism is related to a systemic inflammatory
response. Different target organs are affected due to the activation
of the innate immune system, resulting in a significant release of
inflammatory cytokines,4 with the pathophysiology resembling the
“cytokine storm” seen in graft-versus-host disease (GvHD).5 The longer-
term effects of ionizing radiation have been related to persistent
inflammatory signs, e.g. increased levels of tumor necrosis factor-a
(TNF-a), interferon-b, interleukin-6, and C-reactive protein.6 The
management of patients afflicted with ARS, therefore, relies on those
therapies that both mitigate inflammation7 and are able to aid in the
hematopoietic repopulation of the bone marrow.

Figure 1: Mechanism of action of MSCs in the inflammatory and ischemic
environment. (Source: Pluristem Therapeutics)

Based on these characteristics, mesenchymal stromal cells (MSCs)
would, therefore, seem to be likely candidates as therapeutics for
ARS. MSCs have been shown to be immune-privileged without the need for
HLA matching even after repeat injections7 and have been documented to
home specifically to radiation-injured tissues.8 In addition to
reducing apoptosis,9 MSCs have been shown to secrete an abundance of
therapeutic proteins, including anti-inflammatory and angiogenic
cytokines and hematopoietic growth factors that are involved in the
prevention and treatment of ARS by the reduction of inflammation and
the support of angiogenesis10,11,12 (Figure 1). Additionally, MSCs
have also been shown to promote hematopoietic recovery after lethal
irradiation exposure.7,9

With these attributes, it is no surprise that MSCs have proved to be
effective in animal studies of ARS2,8,9,13 leading to governmental
funding to expand the research and development of MSCs for this
indication. Osiris Therapeutics, a U.S.-based biotechnology company
that uses MSCs derived from bone marrow, secured a contract with the
U.S. Department of Defense in January 2008 for approximately $225
million. $200 million of this amount will be used for purchasing and
stockpiling cell product after efficacy has been demonstrated in two
different animal species and safely documented in humans. This
approval process was employed because it would be unethical to expose
people to high levels of radiation in clinical trials.

While MSCs are usually harvested from bone marrow, they can also be
obtained from other sources such as adipose tissue and peripheral
blood. One of the more recently discovered sources of MSCs that seems
to be highly appropriate is the placenta. The placenta is essentially
medical waste with a ubiquitous supply. Moreover, placental cells can
be easily and inexpensively expanded ex vivo, and be made available as
an allogeneic “off-the-shelf” product.

As with bone marrow-derived MSCs, placental-derived MSCs have been
shown to possess favorable hypo-immunogenic properties, act via the
secretion of anti-inflammatory and angiogenic factors,14 and
potentially provide greater healing powers than older tissue sources.
15 While ARS animal trials are still ongoing, early results have
demonstrated that placental-derived MSCs enhance the engraftment of
hematopoietic stem cells (HSCs) contained in cord blood when the MSCs
and cord blood are administered concurrently.16 This would allow ARS
patients to obtain cells for therapy immediately after exposure, as
well as potentially use cells along with cord blood at a later date to
repopulate the bone marrow if necessary.

In summary, MSCs derived from bone marrow and placentas are actively
being investigated as therapy for ARS. When available, MSCs will be
cryopreserved. Although other cells such as myeloid progenitors are
also being studied as a remedy, MSCs are the only cells being
investigated that would address the entire clinical spectrum and multi-
organ involvement from radiation exposure. A clinical case of ARS has
yet to be treated with MSCs, but these cells have been administered
systemically in patients for graft-versus-host disease (GvHD) and
other indications without significant adverse side effects.

Radiation: Like an Angel's Smile

A medical doctor in Koriyama City in Fukushima Prefecture has a
cheerful message about radiation exposure after the Fukushima I Nuke
Plant accident. As you've already heard from the other good doctor
Shunichi Yamashita, yes indeed, "radiation is good for you", and it is
good for Fukushima's future.

The doctor has a slide presentation on radiation in Fukushima
Prefecture on his website and this is his conclusion:

Conclusion: A small radiation is good for your health

There are two sides to radiation.

Small dose: Like an angel's smile (even at 50 millisieverts/year)

Large dose in short time: Like a devil's violence

From now on, the number of cancer patients in Fukushima will decrease.

Food items with a small amount of radiation will fetch "premium".

Fukushima Prefecture will be the Number One health land in Japan, and
people will flock to Fukushima.

Our future is bright.

Like Disneyland, I suppose.

His conclusion is that Fukushima has "an angel's smile", i.e. almost
harmless, if not beneficial, small amount of radiation.

Looking at his presentation, he seems to have come to the conclusion
because:

Fukushima has received a small amount of radiation when it rained on
March 15 and radioactive iodine and cesium that were in the air fell
on the ground with the rain because of the events on March 14 and 15
(Reactors 2, 3, 4 had explosions) that released a relatively large
amount of radioactive materials;

Now it's mostly only cesium on the surface emitting gamma rays;

They will never know the radiation exposure level in Fukushima until
actually measured;

There are people living in the places with high radiation; and

There are data to prove that the long-term radiation exposure of 50
millisieverts/year decreases the number of cancer cases.

He tells us to just think of it as soaking in a radium [radon] hot
spring (hormesis effect), particularly if we're over 40.

Still, the doctor thinks that the community should do everything to
protect children. His suggestion? Surround them with lead panels that
will block radiation. (Lead poisoning anyone?)

What we can do for children:

Remove surface soil from schoolyards.

Put up lead panels on classroom walls.

Shorten the commute time to and from school.

Drive children to school, and school should allow cars inside the
school gate.

Shield children's room in the house with lead.

Shield children's bed with lead.

If these measures cannot avoid 1 millisievert/year radiation exposure,
then consider relocating children.

It seems to me to be infinitely better not to use lead panels around
children and simply relocate them first, but I am no doctor.

Dr. Shunichi Yamashita Will Become Vice President of Fukushima Medical
University

The diabolical country on the western edge of the Pacific Ocean (no
it's not North Korea) that is what Japan seems to have morphed into
will have Dr. Shunichi "100 microsieverts/hour radiation is safe"
Yamashita of Nagasaki University as the vice president of the
Fukushima Medical University in charge of setting up an organization
to conduct research on effects of radiation on the Fukushima
residents.

Well, those in Fukushima and elsewhere who wanted to remove the
professor from the Fukushima radiation advisor sort of got their wish.
He just made a lateral move. Or maybe he will continue to be the
advisor. Criticism? What criticism?

Note the article below is the Western Japan Edition. I do not know if
the Eastern Japan Edition, which covers Kanto and Toku regions
including Fukushima Prefecture, has the same article. Herr Professor
is not very popular over in the Eastern Japan.

From Mainichi Shinbun Japanese, Western Japan Edition (7/8/2011; link
added):

Professor Shunichi Yamashita (age 59) of Nagasaki University, who has
been the advisor for the Fukushima Prefecture on radiation health
risks in response to the Fukushima I Nuclear Power Plant accident,
will take a leave of absence from Nagasaki University as of July 11
and become the vice president of the Fukushima Medical University
sometime in mid July. It was decided on July 6 in the faculty meeting
at Nagasaki University Graduate School of Biomedical Sciences.
[Professor Yamashita is the dean of the school.]

Professor Yamashita is from Nagasaki City, a "Hibaku Nisei" (2nd
generation sufferer of atomic bomb radiation). He was active in
medical support when the Chernobyl Nuclear Plant accident took place
in 1986. He was also the head of the research center for emergency
radiation exposure under the WHO.

He was invited to Fukushima by the governor of Fukushima on March 18
right after the plant accident, and has been giving lectures on the
importance of "being properly afraid" of radiation. He will
participate in the radiation exposure survey of all 2.02 million
residents of Fukushima. At the Fukushima Medical University, he will
continue the radiation surveys and will be involved in setting up an
organization to study the effect of radiation.

The media (and Professor Yamashita) never fails to mention that he is
a "Hibaku Nisei" (second-generation of the people who were exposed to
radiation from atomic bombs). There are many others who go about their
lives without advertising it or wearing it as some kind of credential
for their work (like Professor Yamashita does all the time).

An anonymous reader of my Japanese blog sent the link to this article,
along with his comment:

"He will be all smiles with such a great number of research subjects
right in front of him, I suppose."

To review Professor Yamashita's remarks in front of a worried
Fukushima City audience, go to my post. There's a youtube video with
English subtitles, linked below. Just look at his mannerism as he
blatantly lies to the audience when he assures "internal radiation is
far less damaging than external radiation".

The funny and immensely sad thing about the video is not so much of
the video itself, but the comments left on the site that has this
video. Instead of attacking the professor, they attack the persons who
created and uploaded the video for being an America's agent (because
English is used, supposedly) or for using a junior high school level
English and speculate the creator probably can't even read the Times.
(I don't know which Times they mean - NYT or the British paper - but
they probably don't even know the difference.)

Chinese Tourists Are Back, Because They WANT Radiation

On a lighter note, Chinese tourists are back in Japan, particularly
young couples, according to an article that appeared in Shukan Post, a
Japanese weekly magazine. Chinese were among the first to depart en
masse from Japan after the earthquake/tsunami/nuke plant disaster, and
they avoided Japan altogether in April.

Why are they back now? Because they WANT to get exposed to radiation.
Why? Because they believe that would get them a baby boy. It's got to
be another "baseless rumor"; high-IQ and rich Chinese wouldn't do such
a silly thing as trying to be intentionally exposed to artificial
radiation hoping that would get them a boy, would they?

From Shukan Post article (July 22/29 issue) as appeared in Iza:

We hear that tours to Japan are becoming very popular among young
Chinese couples.

We still remember the local airports crowded with Chinese citizens
returning home upon the recommendation from their government. Why
would the Chinese, who fled in a radiation panic, come back? There
seems to be a reason behind it which we cannot totally be happy about.

"It's because a German study was reported in a Chinese paper that
radiation exposure increase the chance of conceiving a baby boy", says
a China-based Japanese journalist.

On June 8, Beijing Evening News carried the article titled "Radiation
increases male babies". The article cited a dubious study that the
ratio of male babies increased in Europe and the US during 1960s and
1970s when nuclear testing was done frequently, in Beralus 2 years
after the Chernobyl accident, and in Germany and Switzerland in areas
near nuclear power plants.

Net-savvy Chinese immediately responded to the article. The Chinese
version of Twitter [I suppose it has nothing to do with Twitter but a
Twitter-like service in China] was flooded with messages like "If you
want a boy, go to Japan", "I'm going to buy a airline ticket to Japan
right now", "Travel agencies should arrange "Boy Conception Tours"."
And conspiracy theories like "It must be the false information
concocted by "small" Japanese to revive the tourism from China."

We inquired the Japanese Consul in Shenyang. There was no issuance of
visitor's visa to Japan, and only 23 in May. But in June the number
exploded to 1,900.

A tour guide at a Japanese travel agency that cater to group tours
from China says with a wry smile, "When I guided the Mount Aso in
Kyushu, a newly wed Chinese couple asked me, 'How high is the
radiation level?" When I told them there was nothing to worry about
there, they were very disappointed. They said they wanted to have a
baby boy."

This particular couple probably didn't bother to look at the map of
"small Japan". The island of Kyushu is as far away as you can get from
Fukushima I Nuke Plant. They should be enjoying the hot spring resort
near the plant with the "Genpatsu Gypsy" workers (read the Guardian
report).

The Japanese version of the same "baseless rumor" about radiation and
conception is that if you work in a nuclear power plant you are more
likely to get a baby girl, not boy. Maybe it's different with Chinese.

Leukemia Breakthrough - Serial Killer T Cells Wipe Out Tumors In Small
Trial

In a small trial of advanced chronic lymphocytic leukemia (CLL)
patients, genetically modified versions of their own T cells behaved
like "serial killers" and hunted down and obliterated tumors,
resulting in sustained remissions of up to a year. The breakthrough
gene therapy treatment has been 20 years in the making, and provides a
roadmap for other cancers, say researchers from the University of
Pennsylvania's Abramson Cancer Center and Perelman School of Medicine,
who report the results in a study published today, 11 August, in two
journals: the New England Journal of Medicine and Science
Translational Medicine.

The pilot trial of three patients is the first to show how gene
transfer therapy can create "serial killer" T cells aimed at cancerous
tumors, and the team, led by senior author Dr Carl June, director of
Translational Research and a professor of Pathology and Laboratory
Medicine in the Abramson Cancer Center, believe the protocol they have
developed can be used to develop treatments for other cancers,
including ovarian and lung cancers, and myeloma and melanoma.

The three patients in the trial had advanced CLL and their only hope
of a cure was a bone marrow transplant, a procedure that requires long
stays in hospital and carries a 1 in 5 chance of death. Even then, the
chance of a cure is at best 50%, said the researchers.

For the study, the researchers removed patients' own T cells (a type
of white blood cell), modified them in Penn's vaccine production labs,
then infused them back into the patients' bodies after chemotherapy.

June told the press that the treatment worked much better than they
thought it would:

"Within three weeks, the tumors had been blown away, in a way that was
much more violent than we ever expected."

Co-senior investigator Dr David Porter, professor of Medicine and
director of Blood and Marrow Transplantation at Penn, said:

"Most of what I do is treat patients with no other options, with a
very, very risky therapy with the intent to cure."

"This approach has the potential to do the same thing, but in a safer
manner," he explained.

June said after the patients received their modified T cells, they
replicated more than 1,000-fold in each patient. "Drugs don't do
that," he said.

The T cells not only replicated themselves profusely, but each T cell
killed thousands of tumor cells: they were literally "serial killers".
Overall, they destroyed at least two pounds of tumor in each patient,
said June.

The reason this trial appears to have achieved miraculous results when
other trials using modified T cells have been disappointing, is
because of several "secret ingredients" as June describes them. These
include the fact the modified T cells targeted specific cells only,
leaving healthy cells intact, thus fewer side effects, and also, when
it meets a target cell, the modified T cell sends out signals that
trigger other T cells to replicate, the result being a vast, self-
multiplying growth in numbers of T cells that overwhelm the tumor and
obliterate it.

The researchers write about the immunotherapy and how they
reprogrammed the T cells in the Science Translational Medicine paper,
while the New England Journal of Medicine deals with the effects of T
cell replication in the case of one patient.

The researchers genetically modified the T cells they removed from the
patients using a lentivirus vector. This gives the T cell the ability
to express an antibody called chimeric antigen receptor (CAR). The
CAR, which sits on the surface of the cell, with a part submerged also
inside the cell, binds to a specific antigen, a protein called CD19,
which is expressed only on certain other cells, including CLL tumor
cells and normal B cells (another type of white blood cell). The act
of binding CAR to CD19 initiates cell death in the target cell.

Once they start to express CAR, the T cells focus all their killing on
cells that express CD19, ignoring all other cells. This greatly helps
to minimize the side effects normally seen in standard therapies.

But the team went further than just give the T cells the ability to
express CAR: they engineered a signalling molecule inside the CAR, the
part that sits inside the cell. This signalling molecule is activated
when the CAR binds to CD19, and produces cytokines that tell other T
cells to multiply, creating an avalanche of serial killer T cells.

The NEJM paper describes how one patient, a 64-year-old man, responded
to this treatment. When he joined the study, his bone marrow was
riddled with tumor cells. Then he received his treatment, and for the
first two weeks, nothing seemed to be happening.

But, on day 14, he started having chills, nausea, fever, and other
symptoms, and tests showed a huge increase in T cells in his blood. He
had tumor lysis syndrome, which is when a lot of cancer cells die in a
short space of time.

But only two weeks later, by day 28 after treatment, he had recovered
from tumor lysis syndrome, and tests on his blood and marrow showed no
signs of leukemia.

Porter said:

"This massive killing of tumor is a direct proof of principle of the
concept."

The cell culture method that the researchers used also resurrected T
cells that the leukemia had suppressed, causing the generation of
"memory" T cells, which they hope will give patients ongoing
protection against the cancer recurring.

Although this study was not designed to test the long term effects of
the treatment, there is evidence, nonetheless, that months after
infusion, the new cells had replicated and were able to continue
killing cancer cells throughout the patients' bodies.

The team now plans to test their CAR-CD19 method on patients with
other types of CD19-positive cancers, such as non- Hodgkin's lymphoma
and acute lymphocytic leukemia, and they plan to study how they might
apply it to pediatric leukemia patients, where standard therapy has
not been able to help them.

Human Body Might Adapt to Radiation Exposure

Doctors who are regularly exposed to X-ray radiation may undergo
changes in their cells that protect them from the radiation they
encounter, a new study suggests.

These physicians have higher levels of a particular antioxidant called
glutathione inside their red blood cells than physicians who don't use
X-rays regularly, the study showed. In addition, some of these cells
may be better able to self-destruct, which would be protective if they
turned cancerous.

However, it's still not clear whether these changes will be beneficial
in the long run, or reduce the physicians' cancer risk, said study
researcher Dr. Gian Luigi Russo, a senior research scientist at the
National Research Council (CNR) in Pisa, Italy. Instead, these
alterations might be early indicators of a disease, Russo said.

In the meantime, doctors who frequently work around X-rays should take
every precaution to reduce their risk of radiation exposure, the
researchers said.

Adaptation to radiation

Interventional cardiologists are doctors who perform minimally
invasive operations on the heart, and use X-rays to guide them. While
the patients of these procedures receive the highest dose of X-ray
exposure, the doctor encounters radiation that scatters off the
patient and the walls.

The dose during a single operation is low, but it all adds up, the
researchers said. Over a year, an interventional cardiologist may be
exposed to the equivalent of 250 chest X-rays.

"After 30 years of work, this corresponds to a lifetime's increased
risk of developing cancer of approximately 1 in 100, although there is
still some uncertainty in these risk estimates," the researchers said.

Russo and colleagues analyzed blood samples from 10 interventional
cardiologists and 10 laboratory hospital workers who were not exposed
to radiation as part of their jobs.

On average, the interventional cardiologists were exposed to 4
millisievert (mSv) of ionizing radiation per year, those some
exposures were as high as 8 mSv. The average person in the United
States is exposed to about 3 mSvs per year from natural sources,
according to the United States Nuclear Regulatory Commission.

The researchers concluded these doctors may be adapting to their
higher radiation exposure based on their levels of molecules called
reactive oxygen species (ROS). ROS molecules can damage DNA if they
get inside cells.

The interventional cardiologists had higher levels of ROS in the
plasma surrounding their blood cells than the other doctors, however,
inside their red blood cells, both groups had the about the same
levels of ROS.

That means that the cardiologists cells were producing more
glutathione, and protecting the cardiologists' cells from seeing their
ROS levels spike, Russo told MyHealthNewsDaily.

Additional studies

The study is "extremely interesting," and shows the body has a way of
changing to limit the negative side effects of radiation, said Dr.
Michael Samuels, a radiation oncologist at the University of Miami
Miller School of Medicine, who was not involved with the study. "At
least on a theoretical basis, this is a mechanism that prevents
radiation from harming those cells," Samuels said.

However, additional studies are needed using larger groups of people
to determine the long-term effects of this type of radiation exposure,
the researchers say. Wearing appropriate shielding material, including
lead aprons, and reducing the radiation dose the patient receives
during these operations, may let doctors reduce their radiation
exposure, Samuels said.

The study is published online today (Aug. 23) in European Heart
Journal.

Pass it on: It's possible exposure to chronic low doses of radiation
may prompt beneficial adaptations in cells, but more research is
needed to confirm this.

Harvesting Toxins

If you talk to employees at one of the US Governments nuclear
facilities long enough, you’re likely to hear a lot of interesting
stories about the early days of dealing with nuclear materials. One,
apparently originating in Oak Ridge, TN, involves an underground tank
and a tree.

Apparently during a regular check of the site some radioactive
contamination was found in the ground near one of the storage tanks.
The area was promptly cleaned up, the soil carted away and replaced,
but the people assigned to figure out how the ground became
contaminated in the first place were stumped. They found no leaks, no
spills, nothing that could have caused the radioactive material to
escape. They checked over the spot for several months to see if the
contamination recurred, which it did not, then finally shrugged and
called it a mystery.

But a year later the contamination was back.

The second time was much like the first. The clean-up went smoothly,
the investigation did not. It was not until the third time the same
contamination recurred in the same place that the investigators found
the culprit – an oak tree. The tree had sunk its roots into the tank,
and was pulling up contaminated material. While one would expect the
whole tree to become radioactive, that wasn’t the case. Instead the
oak preferentially shunted the contaminants to its leaves. Every fall
a new crop of radioactive leaves would hit the ground to mystify the
workers at Oak Ridge, and every winter while they were investigating,
there would be no sign of anything amiss with the tree.

It’s an amusing story, but the ability of that tree has become a major
weapon in the efforts to clean up contaminated soil. You see, trees
aren’t the only plants that can pull contaminants from the ground.
There are a slew of others that can do it too, and they are becoming
more and more valuable in places where the ground has become polluted
or contaminated.

The process is called phytoextraction, and it’s one of a number of
ways ecologists are beginning to use plants in bioremediation – the
treatment of environmental problems. There are plants that can pull
lead, uranium, arsenic, and any number of other contaminants out of
the soil. They can then be harvested, a new crop planted, and the
process repeated until the soil is sufficiently recovered.

The process has already been used with great success. At Chernobyl,
genetically altered sunflowers have been used to clean up two ponds
heavily contaminated with both cesium and strontium, while hemp plants
are being used to clean up the soil. Various companies and
institutions are beginning to jump on the bandwagon. Dr. Ilya Raskin
of Rutger’s University, one of the field’s pioneers, has been working
with members of the Brassica family (mustards), which tests have shown
effective at removing a number of heavy metals. Dupont has found corn
useful for lead, while Phytokinetics, a company in Ohio, is using
trees to clean up deeper soil contamination.

All in all, the field of phytoextraction seems to be one of the most
promising in the efforts to clean up the hundreds of thousands of
sites worldwide (30,000 in the US alone, according to the EPA), that
require hazardous waste treatment. Even if only modestly successful,
the use of plants as contaminant removers could reduce cleanup costs
considerably. Even more promising, phytoextraction is only one aspect
of the whole field of phytoremediation, in which plants are being used
not only to remove toxins, but sometimes to break them down
(phytotransformation), enhance microbial activity (phytostimulation),
or prevent leaching of contaminants in the first place
(phytostabalization).

Perhaps if they had known where it would lead, the site workers at Oak
Ridge might have been less frustrated when they finally found their
answer.

Electrified Bacterial Filaments Remove Uranium from Groundwater

Mechanism by which microbes scrub radioactive contamination revealed

Hair-like filaments called pili enable some bacteria to remove uranium
from contaminated groundwater. The discovery, published today in
Proceedings of the National Academy of Sciences, could aid in the
development of radioactivity clean-up technologies.

Some bacteria, including a species called Geobacter sulfurreducens,
are known to get their energy from reducing — or adding electrons to —
metals in the environment. When uranium dissolved in groundwater is
reduced in this way, the metal becomes much less soluble, reducing the
spread of contamination.

Researchers have been trying to find out how the process works. They
suspected that the pili might be the answer, but because G.
sulfurreducens produces pili only in certain environments, the process
has proved tricky to study.

Key to the discovery was getting Geobacter to make pili under lab
conditions, for example by lowering the temperature. "Standard culture
conditions are like a five-star hotel for Geobacter," says Gemma
Reguera of Michigan State University in East Lansing, who led the
research. "We had to make life a little rougher for them."

Reguera and her team were then able to show that the pili greatly
increase the amount of uranium that G. sulfurreducens is able to
remove. Without pili, the bacterium reduces uranium within the cell
envelope, but this poisons the cell in the process. When pili are
present, however, most of the precipitation occurs around the pili,
which extend away from the cell. This provides a greater surface area
for electron transfer, say the researchers, as well as keeping the
radioactive uranium at a safe distance.

An electrifying tale
"This work ties a lot of things together," says Derek Lovley, a
microbiologist at the University of Massachusetts Amherst and
Reguera's former postdoctoral supervisor.

Earlier this year, Lovley published a paper in Nature Nanotechnology
showing that the pili on G. sulfurreducens are a type of 'nanowire',
because they conduct electricity. The pili help to power the bacterium
by transferring electrons produced during the cell's metabolism to
external acceptors such as iron. The fact that pili can also reduce a
metal such as uranium "provides further evidence for long-range
electron transfer along the pili", he says.

The research should help to improve bioremediation — the use of
biological organisms to remove pollutants from soil and water — such
as clean-up of the many sites contaminated by uranium processing
during the cold war. "Current methods to stimulate the growth of these
bacteria in the environment are pretty crude and empirical," says
Lovley. "This new mechanism will allow us to better predict how
uranium can be depleted."

Reguera is most excited about the possibility of "getting away from
the bugs" and making non-living devices based on nanowires. "This
would allow us to work in sites where bacteria cannot live," she says,
such as the Fukushima nuclear plant in Japan, which was devastated by
a tsunami earlier this year.

Uranium is not the main radioisotope released at Fukushima, but
Reguera sees potential for widening the reach of Geobacter pili. In
theory, she says, they could help to precipitate out the radioactive
isotopes of other elements, such as technetium, plutonium and cobalt.
Reguera also envisages fine-tuning the properties of the pili:
"Because these nanofilaments are made from protein, we can easily add
different functional groups," she says.

Microbiologist Yuri Gorby of the University of Southern California in
Los Angeles is optimistic about an emerging field that he refers to as
"electromicrobiology". He points out that other microbes, such as
photosynthetic cyanobacteria and thermophilic methanogens, also
produce conductive nanowires. "I believe that we have only just begun
to scratch the surface," he says.

Japanese Critic Plans "Hotel Radioactivity" in Fukushima (Seriously)

A Japanese critic and commentator with numerous books and writings to
his credit says he's planning to build a hotel in Fukushima Prefecture
to benefit from the hormesis effect of low-dose radiation.

I don't know anything about this person, never read his book or
writings (if you read Japanese, this is his wiki entry). Since the
Fukushima I Nuke Plant accident, he has apparently amassed a huge
following among those who believe radiation is safe as exists right
now in Japan and heavily criticize anyone who disagree with them,
experts or lay people.

For a different point of view, from Mr. Takahiko Soejima's post on his
site, dated October 18 and posted on October 19, 2011 (my translation
hardly does justice to the original Japanese):

I cannot just leave the Miyakoji [about 20 kilometers from Fukushima I
Nuclear Power Plant] headquarters to my disciples and local
supporters. I am thinking about building a "Health Land" or a "Hotel
Radioactivity" to prove "low-level radiation exerts beneficial effect
on human body", in collaboration with Mr. Shinichi Nakaya, a religious
scholar. Again, our stupid enemies who say "Radiation is so so scary"
will no doubt make a racket about my "Hotel Radioactivity" (it's not
"Hotel California" or "Atomic Cafe").

Seriously, these idiots are just hopeless with their radiation phobia
stuck inside their brains, combined with their inherent cowardice and
inability to think calmly and judge things.

Since the beginning of the nuclear accident in March, our group has
done a tremendous job in Fukushima, dispatching the objective news and
writing "Such a ultra-minute amount of radiation does not harm human
body". However, [these idiots] are still not convinced, and continue
to spew their stupid words of radiation phobia.

No need to go to Fukushima, you can get your dose even down in Tokyo:

Tokyo to become dumping ground for radioactive rubble from Fukushima
disaster

Authorities from Fukushima and other disaster-stricken areas in Japan
say they do not have the capacity to process and dispose of all the
radioactive rubble left over from the massive earthquake and tsunami
that struck back in March.

A large portion of that waste is going to be transferred to Tokyo,
according to a recent report by The Mainichi Daily News, a move that
some are concerned may result in additional environmental and human
harm.

The massive amount of wrecked vehicles, destroyed homes and structures
that were generated in eastern Japan after the 9.0+ earthquake and
tsunami is simply too much for local processing facilities to handle.
Reports indicate that some coastal areas generated as much as 4.35
million metric tons of waste each from the disaster, and local
facilities are running far short of intended capacity in meeting the
central government’s processing and disposal deadline.

After discussing the issue with various local authorities, officials
in Tokyo have agreed to accept roughly 500,000 metric tons of this
waste at its local facility, which it plans to gradually dispose of
over a two-and-a-half year period. About 1,000 tons of it are already
set to be transported by freight train to processing facilities near
Tokyo, where it will either be burned or buried depending on its
contamination level.

But how radioactive is this waste, truly, and is it safe to begin
transporting large amounts of it to areas located in very close
proximity to Japan’s largest population center? Many are now asking
this question as the government moves forward with its plans,
especially since ash left over from burning contaminated rubble has in
some cases exceeded 100,000 becquerels per kilogram (Bq/kg) (http://
mdn.mainichi.jp/mdnnews/news…).

Tokyo authorities say they will continually monitor the imported waste
to make sure it does not exceed the 8,000 Bq/kg maximum limit set by
the national government. In a recent sample taken, authorities
detected only 133 Bq/kg of radioactive cesium in ash left over from
rubble incineration at one location, which is well below the maximum
limit.

The total cost of disposing of radioactive rubble created by the
disaster is expected to top one trillion yen, according to Japan’s
Environment Ministry. And this does not include the costs associated
with maintaining temporary storage facilities or testing the waste’s
radiation levels, which could add several trillion more yen to that
total

Japanese Critic Plans "Hotel Radioactivity" in Fukushima (Seriously)

A Japanese critic and commentator with numerous books and writings to
his credit says he's planning to build a hotel in Fukushima Prefecture
to benefit from the hormesis effect of low-dose radiation.

I don't know anything about this person, never read his book or
writings (if you read Japanese, this is his wiki entry). Since the
Fukushima I Nuke Plant accident, he has apparently amassed a huge
following among those who believe radiation is safe as exists right
now in Japan and heavily criticize anyone who disagree with them,
experts or lay people.

For a different point of view, from Mr. Takahiko Soejima's post on his
site, dated October 18 and posted on October 19, 2011 (my translation
hardly does justice to the original Japanese):

I cannot just leave the Miyakoji [about 20 kilometers from Fukushima I
Nuclear Power Plant] headquarters to my disciples and local
supporters. I am thinking about building a "Health Land" or a "Hotel
Radioactivity" to prove "low-level radiation exerts beneficial effect
on human body", in collaboration with Mr. Shinichi Nakaya, a religious
scholar. Again, our stupid enemies who say "Radiation is so so scary"
will no doubt make a racket about my "Hotel Radioactivity" (it's not
"Hotel California" or "Atomic Cafe").

Seriously, these idiots are just hopeless with their radiation phobia
stuck inside their brains, combined with their inherent cowardice and
inability to think calmly and judge things.

Since the beginning of the nuclear accident in March, our group has
done a tremendous job in Fukushima, dispatching the objective news and
writing "Such a ultra-minute amount of radiation does not harm human
body". However, [these idiots] are still not convinced, and continue
to spew their stupid words of radiation phobia.

No need to go to Fukushima, you can get your dose even down in Tokyo:

Tokyo to become dumping ground for radioactive rubble from Fukushima
disaster

Authorities from Fukushima and other disaster-stricken areas in Japan
say they do not have the capacity to process and dispose of all the
radioactive rubble left over from the massive earthquake and tsunami
that struck back in March.

A large portion of that waste is going to be transferred to Tokyo,
according to a recent report by The Mainichi Daily News, a move that
some are concerned may result in additional environmental and human
harm.

that were generated in eastern Japan after the 9.0+ earthquake and

==============================================================

There was a very inneresting documentary on cable just the other day, on the
wildlife at Chernobyl.....
Seems to be thriving.
Similar reports for other radioactive areas. Mebbe some accelerated
evolution??

People seem to be worse for nature than effing radioactivity.... Go
figger....

Be aware, tho, that every time Japan has a disaster, China celebrates, cuz,
well, Japan slaughtered/vivisectioned up to 39,000,000 chinese in 10-15
years, essentially dwarfing the jewish holocaust -- which, actually, has
been dwarfed many times over in many places, including Stalin exterminating
his own returning soldiers, amongst millions of others.

Not diminising the jewish holocaust, just saying many worse holocausts do
not, and likely never will, get their proportional press.
PR, donchaknow.....

"Chernobyl–Up to 5 microseiverts an hour, well above their evacuation
standard.
Tokyo Supermarket–At least 110 microseiverts an hour, well within the
smile-it-won’t-hurt-you zone.

The government is in total crisis management which in new millennium
doublespeak translates to Bullshitting the masses.

They want Tokyo to remain productive and so do all the other players
in this global economy that serves the Extreme Rich.

Don’t think this is an end game event just more people in the future
will die of cancer and other illnesses. So why take apart the Tokyo
economic engine? It will keep running as long as people need jobs and
can’t see radiation anyways.

As long as people aren’t falling down dead on the street they can
maintain the lie."

----------------------------------

Why there are so many hotspots found in Setagaya-ku which is 220 km
from the Fukushima meltdowns? Could the Fukushima disaster uncover
radioactive contamination from other sources in the Japanese capital?
METI may be busy preparing next set of radioactive bottles to be
buried under the asphalt like in the previous case ...

Miso Soup: Powerful Antidote to Radiation
"Spirulina and chlorella have been used heavily by the Russians after
the Chernobyl nuclear plant disaster. And the Japanese love their miso
soup and that was said to help some of their citizens survive the
fallout after the Americans attacked two of their cities. We recommend
a green powder in high doses that is high spirulina and chlorella
content because it is like rocket fuel for the cells, providing them
with a broad range of concentrated nutrients.

Miso is effective for detoxifying your body of radiation. During World
War II, two hospitals that were located side by side were hit with
atomic radiation, in one hospital people consumed Miso and all of them
survived while many people in the other hospital that did not take
miso died. Miso is rich in vitamin B12 therefore it is suitable for
vegetarians who are in shortage of vitamin B12. For best results do
not cook miso."
