What Happens When You Pee (i.e. urine mixes with pool chemicals)
in the Pool?

What Happens When You Pee in the Pool?

By Dr. Mercola
One in five Americans admit they have peed in a pool, and among
Olympic swimmers, the practice is so widespread that a former US
National team member said nearly 100 percent of competitive
swimmers pee in the pool… regularly.1
Swimming in a urine-contaminated pool is certainly not the most
pleasant thought, but is it really so bad?
Olympic swimmer Michael Phelps doesn't think so, and famously
said that "chlorine kills it [urine]," making peeing in the pool
a non-issue. But it's not the urine itself that you need to
worry about.
Urine is virtually sterile when it leaves your body, so it
doesn't pose the risk of causing illness the way fecal matter in
a pool does. In fact, urine is a valuable source of nutrients
that is now being used as an effective and natural fertilizer.
So it's not the urine that is the problem… it's what happens
when urine mixes with pool chemicals, including chlorine, that
is catching researchers' attention.
Peeing in the Pool Creates a Chemical Warfare Agent :o :P
Highly toxic disinfection byproducts (DBPs) form from reactions
between pool disinfectants and organic matter, including hair,
skin, sweat, dirt and… urine. In a new study, researchers mixed
uric acid from human urine with chlorine and found it creates
two DBPs: cyanogen chloride (CNCl) and trichloramine (NCl3).2
HTML http://www.freesmileys.org/emoticons/emoticon-object-015.gifhttp://www.desismileys.com/smileys/desismileys_1593.gif
[move]
The former, CNCI, is classified as a chemical warfare agent and
is a known toxicant to your lungs, heart, and central nervous
system. NCl3 is linked to lung damage.[/move]
As for how dangerous this is, practically speaking, the
researchers found that, in a worst-case scenario, urine in a
pool might lead to about 30 parts per billion (ppb) of cyanogen
chloride, which is well below the 70 ppb used as the maximum
cyanogen concentration allowed in drinking water, according to
the World Health Organization (WHO).3
Cyanogen chloride leads to coma, convulsions and death only at
much higher levels (about 2,500 ppb), an amount that would be
difficult, and probably impossible, to generate in a typical
swimming pool from urination alone.4 This doesn't mean that
smaller doses are "safe," however, as DBPs have been linked to
serious health problems at levels found in swimming pools.
According to the study researchers, since urinating in a pool
introduces uric acid that will lead to the formation of a poison
when it interacts with chlorine, it should be avoided:
" …uric acid chlorination may account for a large fraction of
CNCl formation in swimming pools. Moreover, given that uric acid
introduction to pools is attributable to urination, a voluntary
action for most swimmers, these findings indicate important
benefits to pool water and air chemistry that could result from
improved hygiene habits on the part of swimmers."
[move]
Spending Just 40 Minutes in a Chlorinated Pool May Lead to DNA
Damage[/move]
If you've ever wondered if the chlorine in a swimming pool poses
a health risk, you'll find it unsettling to know that the DBPs
created by chlorine reactions are far more dangerous. In fact,
when researchers measured evidence of genotoxic (DNA damage that
may lead to cancer) and respiratory effects on swimmers who swam
in a chlorinated pool for just 40 minutes, they found:5
•Increased micronuclei in blood lymphocytes, which are
associated with cancer risk
•Urine mutagenicity, a biomarker of exposure to genotoxic agents
•An increase in serum CC16, which suggests an increase in lung
epithelium permeability
Adding chlorine to a swimming pool results in the formation of
hundreds of DBPs because of the organic matter in the water. The
researchers found that total concentrations of four DBPs
(trihalomethanes (THMs)) were seven times higher in exhaled
breath after swimming than they were before. :P They noted:
"Our findings support potential genotoxic effects of exposure to
DBPs from swimming pools. The positive health effects gained by
swimming could be increased by reducing the potential health
risks of pool water."
DBPs in Swimming Pools Are Linked to Cancer
It's known that trihalomethanes (THMs), one of the most common
DBPs, are Cancer Group B carcinogens, meaning they've been shown
to cause cancer in laboratory animals. They've also been linked
to reproductive problems in both animals and humans, such as
spontaneous abortion, stillbirths, and congenital malformations,
even at lower levels.
It's not only swimming pools that are problematic, as DBPs also
exist in chlorinated drinking water. Ingesting chlorinated water
with levels of DBPs common in many industrialized countries has
been linked to an increased risk of bladder cancer.6
However, when researchers also looked at exposure to DBPs
through your skin and via inhalation (such as occurs while
showering, bathing and swimming in pools), it was found to be an
even greater risk than drinking water.7
Furthermore, people who frequent swimming pools have an
increased risk of bladder cancer compared to those who do not,8
and DBPs have even been suggested as partially responsible for
the increased risk of melanoma cancer among swimmers.9
According to one study published in the Journal of Environmental
Sciences,10 the cancer risk of DBPs (in this case THMs) from
various routes in descending order was:
1.Skin exposure while swimming
2.Gastrointestinal exposure from tap water intake
3.Skin exposure to tap water
4.Gastrointestinal exposure while swimming
The cancer risk from skin exposure while swimming comprised over
94 percent of the total cancer risk resulting from being exposed
to THMs! The authors even went so far as to conclude that
swimming in a chlorinated pool presents "an unacceptable cancer
risk."
DBPs Pose Risks of Allergies, Asthma, and Other Health Problems
Most public pools are overloaded with chlorine, as the
well-intentioned people who maintain public pools overly shock
them with chlorine to make sure bacteria and other organisms get
snuffed out quickly. But even the swimming pool in your backyard
could be toxic if you treat it with chlorine – even if you know
no one is using it to pee in.
Remember, any organic matter – including hair, skin, sweat, and
dirt – can react with chlorine to create DBPs. So if you use
chlorine, it's going to be virtually impossible to avoid some
exposure. Many studies have pointed out the health risks
associated with swimming in chlorinated water, and many of these
are related to toxic DBPs:
•Swimming instructors are more than twice as likely to suffer
frequently from sinusitis or sore throat, and more than three
times as likely to have chronic colds, than pool workers with
less DBP exposure, such as catering employees or
receptionists.11
•Compared to the general population, pool workers with high
levels of exposure were at a 40 percent greater risk for
tightness of the chest and were over 700 percent more likely to
suffer breathlessness while walking.12
•DBPs may cause weakening of your immune system, disruptions to
your central nervous system, damaging effects to your
cardiovascular system, unhealthy functioning of your renal
system and harmful impacts to your respiratory system.
Should You Avoid Swimming Pools? ???
The risk of DBP exposure from swimming pools is real, but it
doesn't necessarily mean you have to give up swimming. Swimming
in an ocean
HTML http://www.pic4ever.com/images/shrk.gif
;D is an
excellent alternative, as is swimming in a lake or other
natural body of water. You can also find a way to keep your pool
clean from bacteria, algae, and other organisms without the use
of dangerous chemicals, such as choosing a saltwater pool.
HTML http://www.pic4ever.com/images/47b20s0.gifhttp://www.pic4ever.com/images/128fs318181.gifhttp://www.desismileys.com/smileys/desismileys_0293.gif
One of the best solutions is NOT to chlorinate your pool and
just use a maintenance "shock" treatment every five or six days,
which will kill the algae buildup. The shock treatment
volatilizes in about 24-48 hours and gives you a several-day
window in which you can safely use your pool. You can also
reduce the amount of organic material you bring into the pool,
and thereby the amount of DBPs created, by showering prior to
entering and teaching your children
HTML http://www.desismileys.com/smileys/desismileys_6869.gif
not to
urinate in the water. You can also use ozone, which also
oxidatively destroys the pool pathogens and lowers the need for
chlorine.
This will be difficult if you're visiting a public swimming pool
or waterpark, however. Surveys show that 35 percent of Americans
say they do not shower prior to entering a pool. Finally,
because DBPs exist in all chlorinated water, I recommend
installing water filters that remove chlorine for both your
shower/bath and your kitchen tap.

Water-based 'engine' propels tumor cells through tight spaces in
the body
By: AGelbert Date: April 30, 2014, 2:24 pm
---------------------------------------------------------
Water-based 'engine' propels tumor cells through tight spaces in
the body
Johns Hopkins researchers have discovered a new mechanism that
explains how cancer cells spread through extremely narrow
three-dimensional spaces in the body by using a propulsion
system based on water and charged particles.
The finding, reported in the April 24 issue of the journal Cell,
uncovers a novel method the deadly cells use to migrate through
a cancer patient's body. The discovery may lead to new
treatments that help keep the disease in check. The work also
points to the growing importance of studying how cells behave in
three dimensions, not just atop flat two-dimensional lab dishes.
Based on such lab dish studies, cancer researchers had concluded
that tumor cells require actin and other proteins to form
arm-like extensions to "crawl" across the flat surfaces. This
type of travel was believed to be the primary means of how
cancer spreads within a patient, a process called metastasis.
Based on this conclusion, researchers have been working on ways
to disable actin and its molecular helpers, hoping this can keep
cancer from spreading.
But in a study published in 2012, a Johns Hopkins team led by
Konstantinos Konstantopoulos, chair of the Department of
Chemical and Biomolecular Engineering, found that tumor cells
could move through narrow spaces without using actin and its
biochemical partners.
"That was a stunning discovery, not in line with the prevailing
beliefs about how cells migrate," Konstantopoulos said. "So we
wanted to figure out exactly how the tumor cells were able to
move through these spaces without relying on actin."
He collaborated with Sean X. Sun, a Johns Hopkins associate
professor of mechanical engineering with experience in math
modeling and physics at microscopic levels.
"The mystery we needed to solve," Sun said, "was how the cells
in these confined spaces could still move when you took away
their usual 'engine,' the actin."

Kostantopoulos said Sun and Hongyuan Jiang, a postdoctoral
fellow working in Sun's lab, "came up with a phenomenal
mathematical model that provided insights into how the cells
might use a different system to travel." Then Konstantopoulos
and other team members, including Kimberly Stroka, a
postdoctoral fellow in his own lab, used a microfluidic
lab-on-a-chip and imaging techniques to conduct experiments
establishing the new mechanism of migration proposed by Sun and
Jiang's model. The tests utilized human and animal cancer cells.
Stroka and Jiang were designated co-lead authors of the
resulting journal article.
As reported in the article, the tumor cells' new "engine" turned
out to be a combination of sodium-hydrogen ions, cell membrane
proteins called aquaporins, and water.
[img width=640
height=380]

Aquaporin
The researchers found that within tight spaces, cancer cells
create a flow of liquid that takes in water and ions at a cell's
leading edge and pumps them out the trailing edge, propelling
the cell forward. In the actin-dependent migration model, the
cell is pushed forward by the biochemical equivalent of a boat
engine. The water-based mechanism, the researchers said, more
closely resembles the way a sailboat is thrust ahead by gusts of
wind. The team called this mechanism the Osmotic Engine Model.
"This discovery is important because it reveals one reason why
some diseases
HTML http://www.pic4ever.com/images/fly.gifhttp://www.createaforum.com/gallery/renewablerevolution/3-311013201314.png<br
/>like cancer don't always respond to certain treatments,"
Konstantopoulos said. Sun added, "It's because these diseases
have redundant mechanisms—more than one method—for migrating
through the body."
Agelbert Note: This discovery is also important because it
underlines the vital importance of maintaining a proper level of
hydration in the human body. DEHYDRATION will slow immune system
response but WON'T slow the cancer mets! :o :P This is another
good reason to stay properly hydrated.

Agelbert NOTE: interesting article on this new test WITH
IMMINENT FDA approval that MAY avoid the cost (and risk from
intestinal perforation) involved in a colonoscopy. ;D I am not
sure yet if that means EXAS is a buy but I'm watching it... ;)
Cologuard Will Dominate Its Addressable Market
May. 19, 2014 10:59 AM ET | 54 comments | About: EXACT
Sciences Corporation (EXAS)
Disclosure: I have no positions in any stocks mentioned, and no
plans to initiate any positions within the next 72 hours.
Summary
•A recent expert interview with a gastroenterologist indicated
that Cologuard has significant market potential.
•Up to 30% of FIT patients would not be suitable for Cologuard,
due to the need for colonoscopies roughly every 3-5 years
anyway.
•Outside of those patients, Cologuard will own its addressable
market and be rapidly adopted by physicians.
•Eventual penetration into the 70% range of this market is
reasonable, and even at $300/test, Exact Sciences is
undervalued.

Does Sugar Overconsumption Really Cause Cancer and Contribute to
Heart Disease? ???
Sugar overconsumption might cause cancer and contribute to heart
disease, research suggests. This is thought to be the result of
extra stress put on the body during the metabolizing of
fructose, or the sugar found in certain plants. Unlike the
carbohydrates found in vegetables and starches that are
metabolized by all of the body’s cells, fructose is metabolized
only by the liver. The increase in metabolizing blood sugar is
thought to cause the cell mutations that result in cancer and
raise the levels of triglycerides, or fat, in the bloodstream,
which can cause heart disease.
More about sugar:
•The average American is estimated to consume about 90 pounds
(40.82 kg) of sugar each year.
•There are about 10 teaspoons (40 g) of sugar in an average can
of soda, which is nearly twice the amount of sugar that health
experts recommend consuming in a day.
•Lower-income people consume the most calories from sugar, at
roughly 15% of their daily intake. People in the highest income
bracket consume only about 11% of their daily calories from
sugar.

One dollar blood test :o ;D using gold nanoparticles
outperforms PSA screen for prostate cancer, study suggests
Date: April 3, 2015

Dr. Qun "Treen" Huo of UCF's NanoScience Technology Center has
developed a prostate cancer test using gold nanoparticles. Pilot
studies found it to be more accurate than the standard PSA test.

A test that costs less than a $1 and yields results in minutes
has been shown in newly published studies to be more sensitive
and more exact than the current standard test for early-stage
prostate cancer.
The simple test developed by University of Central Florida
scientist Qun "Treen" Huo holds the promise of earlier detection
of one of the deadliest cancers among men. It would also reduce
the number of unnecessary and invasive biopsies stemming from
the less precise PSA test that's now used.
"It's fantastic," said Dr. Inoel Rivera, a urologic oncologist
at Florida Hospital Cancer Institute, which collaborated with
Huo on the recent pilot studies. "It's a simple test. It's much
better than the test we have right now, which is the PSA, and
it's cost-effective."
When a cancerous tumor begins to develop, the body mobilizes to
produce antibodies. Huo's test detects that immune response
using gold nanoparticles about 10,000 times smaller than a
freckle.
When a few drops of blood serum from a finger prick are mixed
with the gold nanoparticles, certain cancer biomarkers cling to
the surface of the tiny particles, increasing their size and
causing them to clump together.
Among researchers, gold nanoparticles are known for their
extraordinary efficiency at absorbing and scattering light. Huo
and her team at UCF's NanoScience Technology Center developed a
technique known as nanoparticle-enabled dynamic light scattering
assay (NanoDLSay) to measure the size of the particles by
analyzing the light they throw off. That size reveals whether a
patient has prostate cancer and how advanced it may be.
And although it uses gold, the test is cheap. A small bottle of
nanoparticles suspended in water costs about $250, and contains
enough for about 2,500 tests.
"What's different and unique about our technique is it's a very
simple process, and the material required for the test is less
than $1," Huo said. "And because it's low-cost, we're hoping
most people can have this test in their doctor's office. If we
can catch this cancer in its early stages, the impact is going
to be big."
After lung cancer, prostate cancer is the second-leading killer
cancer among men, with more than 240,000 new diagnoses and
28,000 deaths every year. The most commonly used screening tool
is the PSA, but it produces so many false-positive results --
leading to painful biopsies and extreme treatments -- that one
of its discoverers recently called it "hardly more effective
than a coin toss."
Pilot studies found Huo's technique is significantly more exact.
The test determines with 90 to 95 percent confidence that the
result is not false-positive. When it comes to false-negatives,
there is 50 percent confidence -- not ideal, but still
significantly higher than the PSA's 20 percent -- and Huo is
working to improve that number.
The results of the pilot studies were published recently in ACS
Applied Materials & Interfaces. Huo is also scheduled to present
her findings in June at the TechConnect World Innovation Summit
& Expo in suburban Washington, D.C.
Huo's team is pursuing more extensive clinical validation
studies with Florida Hospital and others, including the VA
Medical Center Orlando. She hopes to complete major clinical
trials and see the test being used by physicians in two to three
years.
Huo also is researching her technique's effectiveness as a
screening tool for other tumors.
"Potentially, we could have a universal screening test for
cancer," she said. "Our vision is to develop an array of blood
tests for early detection and diagnosis of all major cancer
types, and these blood tests are all based on the same technique
and same procedure."
Huo co-founded Nano Discovery Inc., a startup company
headquartered in a UCF Business Incubator, to commercialize the
new diagnostic test. The company manufacturers a test device
specifically for medical research and diagnostic purposes.

Why Can't Naked Mole Rats Get Cancer?
HTML http://www.coh2.org/images/Smileys/huhsign.gif<br
/>
HTML http://www.desismileys.com/smileys/desismileys_1730.gif
According to a study done by the University of Rochester in
2013, naked mole rats do not get cancer because they have
complex sugars that prevent cells from clumping and turning into
cancerous tumors.
Naked mole rats were selected for the study because they live
very long, about 30 years, and do not seem to get cancer. The
study revealed that the reason cells do not clump in naked mole
rats is due to a complex sugar called hyaluronan in the
extracellular matrix, the space between cells.
[img width=640
height=300]
HTML http://patentimages.storage.googleapis.com/EP2289522A1/imgb0001.png[/img]
The study set off discussions about the possibility of altering
hyaluronan sugars in humans or using this specific gene from
naked more rats in the fight against cancer.
More about naked mole rats:
•The naked mole rat is a type of rodent which lives in burrows
in soil. It spends most of its life in darkness.
•Contrary to popular belief, naked mole rats are not blind and
they are not exactly hairless; they have very thin hairs that
help them with navigation.
[img width=640

•Naked mole rats have a social structure similar to some
insects. There are worker and fighter naked mole rats, and a
queen who is the only one who breeds.

[center]Making an informed decision requires being informed. Are
you? [/center]
In the United States, cancer kills six hundred thousand people
each year. Like most wars, the 'war' on cancer is expensive, and
profitable. In that one year, chemotherapy will generate almost
$100,000,000,000 (one hundred billion) of income.
Chemotherapy is effective against certain types of cancer
(leukemia, lymphoma/Hodgkin's), which, taken together, make up a
fraction of all-cancer mortality (<1%). For the major metastatic
cancer killers however (breast, lung, colon, pancreatic),
five-year survival rates have not changed significantly since
the advent of its widespread use. Its side effects are
associated with significant morbidity and even further
carcinogenesis (aka more costs/profits). One might wonder what
happened to the Hippocratic Oath.
Chemotherapy costs $50,000-$70,000 or more per treatment
regimen. Unlike any other prescription drug or treatment,
doctors prescribing chemo make direct profit per sale.
And despite what most oncologists have been taught, if you are
taking radiation or chemo, or both, ...take your anti-oxidants
also. You're more likely to get better, with fewer and less
severe side effects.
Be informed.
