SILVER IS TOXIC
Silver is toxic to human cells.
By Kathleen Too, Deputy Editor.
Silver is commonly used both in ionic form and in nanoparticulate form as a bactericidal agent. This is generally ascribed to a higher toxicity towards prokaryotic cells than towards mammalian cells.
STAY AWAY FROM SILVER
Scientists in Germany have carried out studies to compare silver ions (such as silver acetate) and polyvinylpyrrolidone (PVP)-stabilised silver nanoparticles (70 nm). They found that silver’s toxic effect occurs in a similar concentration range for Escherichia coli, Staphylococcus aureus, human mesenchymal stem cells and peripheral blood mononuclear cells (0.5 to 5ppm for silver ions and 12.5 to 50ppm for silver nanoparticles).
For a better comparison, the team cultivated bacteria in Lysogeny broth medium and in Roswell Park Memorial Institute medium/10% fetal calf serum medium, as the state of silver ions and silver nanoparticles may be different owing to the presence of salts and biomolecules such as proteins. They found that the effective toxic concentration of silver towards bacteria and human cells is almost the same.They found that the effective toxic concentration of Silver towards bacteria and human cells is about the same.

Scientists want to be first to drill into the Earth's mantle; what does this do to the value of gold?

It's because of his constant anti-Trump rhetoric.
We're talking about the same silver, right?

Re: SILVER IS TOXIC
We already know of the affects of copper on bacteria. Silver seems to be more intense. Now what could the affect of gold be?

STANFORD RESEARCHERS PURIFYING WATER WITH SILVER
September 19, 2010 12:00:00 AM PDT
by Richard Hart
PALO ALTO, CA -- Researchers at Stanford have developed a new kind of filter, a cheap and fast way to purify water in poor parts of the world and on camping trips.
In her Stanford laboratory, Alia Schoen purifies water using a new method thousands of times faster than anything previous. It uses nanotechnology and silver.
In the days before milk could be pasteurized or refrigerated, people would drop a silver coin into a bottle to preserve it. Silver is lethal to bacteria. Tiny amounts of silver are already woven into antibacterial socks, underwear and band-aids. You could build water filters out of silver, but the metal is so costly, it would kill your bank account before it killed the bacteria.
Now, nanotechnology is changing that.
It turns out that if you run a minute amount of electricity through microscopic silver, it amplifies its antibacterial powers by thousands of times. The Materials Science Lab at Stanford University is already making the first fabric batteries out of cotton infused with the hottest material in research today: carbon nanotubes.
Professor Yi Chui's team has also infused cotton with microscopic silver nanowires. A member of that team, Dr. David Schoen recalls, "What we thought was a crazy idea at the time, to combine electricity with nanowires to treat water."
The crazy combination of nanosilver and nanocarbon did the trick. It enables them to filter 98 percent of the E. coli in a water sample in one pass using so little electricity, it can run on 9-volt batteries. Professor Cui, of Stanford's Materials Science department says, "We use a tiny amount. So, it is possible to scale this filter up to a very large size. There's no reason we cannot do thousands of gallons quickly."
In fact, all the water used by one average household in a year (20,000 gallons) could be treated in just one hour with a filter the size of a kitchen sink. Safety and commercialization require still more work, but there is huge potential for poor communities.
"The biggest application," Cui is certain, "will be use in remote areas in third world countries."
What's more, with a couple of batteries, you might one day take something like this on a camping trip.

Re: SILVER IS TOXIC
I am not from the camp that suggest you eat it, but the pioneers used to put dimes in their canteens to clean the water, an the old saying "born with a silver spoon in their mouth" wasn't referring to wealth , but as a reference to being able to keep the children healthy. Silver has its place, in my bloodstream no, in my pocket yes.

REMOVE SILVER!!

Most of the time, recurrent decay is found underneath old silver fillings and is the reason for replacing them. Removing silver fillings can be done safely by using a high speed suction and a rubber dam to isolate the tooth from the rest of the mouth. Best, Dr. Elizabeth Jahanian

President Ezra Taft Benson:
"Even though American citizens would still be forced by law to honor the same pieces of paper as though they were real money, instinctively they would rush and convert their paper currency into tangible material goods which could be used as barter. As in Germany and other nations that have previously traveled this road, the rush to get rid of dollars and acquire tangibles would rapidly accelerate the visible effects of inflation to where it might cost one hundred dollars or more for a single loaf of bread. Hoarded silver coins would begin to reappear as a separate monetary system which, since they have intrinsic value would remain firm, while printed paper money finally would become worth exactly its proper value-the paper it is printed on! Everyone's savings would be wiped out totally. No one could escape."

Re: SILVER IS TOXIC
Silver compounds have low toxicity compared to those of most other heavy metals, as they are poorly absorbed by the human body when digested, and that which does get absorbed is rapidly converted to insoluble silver compounds or complexed by metallothionein. However, silver fluoride and silver nitrate are caustic and can cause tissue damage, resulting in gastroenteritis, diarrhoea, falling blood pressure, cramps, paralysis, and respiratory arrest. Animals repeatedly dosed with silver salts have been observed to experience anaemia, slowed growth, necrosis of the liver, and fatty degeneration of the liver and kidneys; rats implanted with silver foil or injected with colloidal silver have been observed to develop localised tumours. Parenterally admistered colloidal silver causes acute silver poisoning. BEWARE OF SILVER!

This is talking about what is referred to as silver fillings, but in reality is about 50% mercury, and the other half silver, tin, and copper alloy/ combination.eddie wrote: ↑April 21st, 2017, 5:16 pm REMOVE SILVER!!
