Silver nanoparticles show 'immense potential' in prevention of blood clots

Scientists are reporting discovery of a potential new alternative to aspirin, ReoPro, and other anti-platelet agents used widely to prevent blood clots in coronary artery disease, heart attack and stroke. Their study, scheduled for the June 23 issue of ACS Nano, a monthly journal, involves particles of silver -- 1/50,000th the diameter of a human hair -- that are injected into the bloodstream.

Debabrata Dash and colleagues point out that patients urgently need new anti-thrombotic agents because traditionally prescribed medications too-often cause dangerous bleeding. At the same time, aging of the population, sedentary lifestyle and spiraling rates of certain diseases have increased the use of these drugs. Researchers are seeking treatments that more gently orchestrate activity of platelets, disk-shaped particles in the blood that form clots.

The scientists describe development and lab testing of that seem to keep platelets in an inactive state. Low levels of the nanosilver, injected into mice, reduced the ability of platelets to clump together by as much as 40 percent with no apparent harmful side effects.

The nanoparticles “hold immense potential to be promoted as an antiplatelet agent,” the researchers note. “Nanosilver appears to possess dual significant properties critically helpful to the health of mankind — antibacterial and antiplatelet — which together can have unique utilities, for example in coronary stents.”

I guess those colloidal silver guys who took so much shit from the medical INDUSTRY..were actually on to something.

Never would have guessed. This seems to be implying that the blood's PH is off subtly when someone has a clotting the body's blood PH is so tightly held to a mean. Otherwise..death.

This means that one might want to look into Jim Humble's MMS.

This has absolutely nothing to do with colloidal silver, because that is a poison and the people involved with it have absolutely no scientific basis in studies for their claims. Just because a study has the word silver in it does not validate every piece of prior pseudoscience that employed the word.

The ACS has done medical research great disservice by promoting silver nanopartices (NPs) as anti-thrombotic agents.

In fact, NPs in the blood stream have been shown to cause DNA damage in nunmerous experiments over the past few decades. NPs as a health hazard are consistent with recent theoretical arguments that show NPs conserve the collisional energy from surrounding solution moelcules by the emission of EM radiation instead of by an increase in temperature.

Similar to conventional radiation sources, the NPs emit UV and higher energy radiation although at low power levels, the process called QED induced radiation. QED stands for quantum electrodynamics.

Inadvertantly, the ACS has promoted the risk of cancer induced from DNA damage. See at link "NP induced DNA damage".
