Stealthy Nanoparticles Attack Cancer Cells

Drugs embedded in special polymers can more effectively shrink tumors.

This article is quoted from Technology Review

In a small manufacturing space on a Cambridge, MA, street dotted with biotech companies, Greg Troiano tinkers with a series of gleaming metal vats interweaved with plastic tubes. The vats are designed to violently shake a mix of chemicals into precise nanostructures, and Troiano's task, as head of process development at start-up BIND Biosciences, is to make kilograms of the stuff--a novel drug-infused nanoparticle. The company hopes the new drug-delivery system will diminish the side effects of chemotherapy while increasing its effectiveness in killing cancer.

Scientists at BIND have shown that their nanoparticles--which are not only infused with drugs but also enrobed in cancer-targeting proteins--can better stop the growth of prostate, breast and lung tumors in rodents. BIND has made particles that can remain in the bloodstream for more than a day, increasing the likelihood that the drug will reach its target tissue. It is also refining a method for making large volumes of its nanoparticle-based delivery system in preparation for clinical trials of its technology in cancer patients next year.

The company's approach is based on self-assembling polymers developed in the lab of Robert Langer, a professor of chemical engineering at MIT and a pioneer in biomaterials research. Langer founded BIND in 2006 with Omid Farokhzad, a scientist and physician at Harvard Medical School and a former postdoctoral researcher in Langer's lab.

"The idea of using nanoparticles is to lower the dose while maintaining efficacy and reducing side effects," says Piotr Grodzinski, director of the Nanotechnology for Cancer Programs at the National Cancer Institute, in Bethesda, MD. Grodzinski said in some cases the nanoparticles could be used to increase the dose while reducing toxicity. This is especially important for chemotherapeutics, which often must be administered in high doses that result in severe side effects--so severe that some patients choose to forgo the treatment.

Swine Flu (H1N1): Definition, Symptoms, Prevention

Previously I post in my blogger information about the 2009 swine flu vaccinations effects on humans being. And based on the above, I decided to post an article about the definition, symptoms and how to prevent your self and family from this pandemic virus, since vaccinations developed arround the world until now are still in the experiment stage or has side effects appear on the long-term. You will find also some useful links to other web sites specialized in this area. Also if you have others you can post them in comments.

Since June 11, 2009, the World Health Organization (WHO) classified the H1N1 flu (some times called swine flu) as a pandemic and warn all the health organizations worldwide to develop strategies to combat and reduce the spread of virus. H1N1 virus spreads from person to person (contagious), probably in much the same way that regular seasonal influenza viruses spread mainly through coughing or sneezing by infected people, sometimes by touching viral infected surfaces or objects then touching their mouth or nose. The good news that most people who have become ill with this new virus have recovered with out requiring medical treatment, by the human immune system and other natural body's defences. Therefore, I will refer again to Dr. Mercola's article I post it earlier which shows the great side effect in H1N1 vaccinations. And therefore may not be needed to address these doses stimulating the immune system, which could harm our health in the long run, but we follow the popular saying "Prevention is better than Cure".

The Swine Flu (H1N1) Vaccine’s Dirty Little Secret Exposed

Actually, while searching over the internet I read this article for Dr. Mercola which shows the secrets of the vaccines used and discovered until now in the world. This article shows the great side effect of these vaccines on the body, specially on the immune system, which will appears as an autoimmune disorder disease a few years later.

These Vaccinations are dangerous even those from Novartis and GlaxoSmithKline because they contains number of chemical toxins, including ethylene glycol (antifreeze), formaldehyde, phenol (carbolic acid) and even antibiotics like Neomycin and streptomycin. In addition to all of these it contain immune adjuvants like aluminum and squalene to enhance (turbo charge) your immune response to the vaccination. Note that the main ingredient in Vaccine is either killed viruses or once that have been attenuated (weakened and made less harmful)....

And here is the secret of these vaccinations it is based on immune adjuvants to overreact to the introduction of the organisms you are being vaccinated against.
