How Carolyn Reversed
Her Alzheimer's by Disobeying Her Doctor
An all-natural protein melts away the
brain-clogging mineral that triggers memory loss, dementia and Alzheimer's — and
cuts brain cell death in half! And yet this Nobel Prize-winning discovery is
being ignored by 99% of doctors.
That's why I'd like to tell you about Carolyn. Click here to see how she reversed her Alzheimer's without drugs — and in just a few weeks! If you or someone you care about is suffering from memory loss, dementia or Alzheimer's, then you know how cruel these diseases can be. The emotional and physical toll they take on the patient — as well as on the entire family — can be devastating. That's why the news of the breakthroughs I'm about to reveal could literally have a life-changing effect on you. Best of all, these solutions are available and being used successfully right now — even while most doctors still throw up their hands when it comes to memory loss, dementia and Alzheimer's, using words like "hopeless" and "irreversible." It's hard to believe, I know. . . So please click here to see how Carolyn reversed her Alzheimer's with this remarkable discovery! |
A privately-held San Francisco company,
Jennerex, Inc., worked with a team of scientists, including some from the
University of Ottowa, to develop the experimental virus
JX-594.
According to study results published in the August 31, 2011 edition of the journal Nature, JX-594 is a virus customized to destroy cancer tumors while leaving healthy cells unaffected.
And researchers were equally excited to find that the only side effects were mild flu-like symptoms that quickly vanished!
No doubt, opponents of genetically-modified-anything are having a fit right now. I think they should relax a little. I don't think genetic technology is all bad, all the time. Like anything else, we should look at each case on its merits.
It seems that JX-594 comes from a strain of virus once used to vaccinate children against smallpox. But the scientists said there's no need to fear an outbreak because the genetic information that would cause viral mutations has been deleted from JX-594.
According to a company statement, researchers administered intravenous JX-594 to 23 patients as treatment for advanced, solid tumors. These tumors had shown themselves resistant to prior treatment efforts.
When the investigators later took biopsies of the tumors, they found that the intravenous doses of JX-594 infected the tumors' blood vessels and choked off their blood supply.
The research team found that six of the eight patients given the highest doses of the engineered virus saw their tumors stabilize or shrink. And seven of those eight patients showed evidence that the virus replicated within their tumors—but not in normal tissues.

Were these results just a stroke of good
luck?
To prove JX-594 is no one-hit wonder, the
researchers performed another trial focused on patients with liver cancer. The
researchers injected JX-594 directly into tumors. They then used magnetic
resonance imaging (MRI) to monitor reduction in blood flow to
tumors.
The results? In just five days following treatment with JX-594, the researchers observed asignificant decrease in the blood supply to tumors—resulting in their destruction. The virus simply starved the tumors to death.
And best of all, the shutdown of blood flow ONLY affected tumor tissue. The researchers noticed NO significant changes in blood supply to healthy tissue!
"In addition to targeting, infecting and destroying cancer cells and stimulating a targeted immune response against remaining cancer cells, the analysis presented at AACR [The American Association for Cancer Research] demonstrates JX-594's critical third mechanism of action—the disruption of the blood supply to the tumor," said David H. Kirn, M.D., president and chief executive officer of Jennerex.
The encouraging results from studies such as those conducted by the Jennerex research team have led to a surge of research investigating similar viruses over the last 15 years.

So what does a virus have to do to get a
little
respect as a cancer killer?
respect as a cancer killer?
The term 'oncolytic' refers to a virus that
can specifically target and destroy tumor cells without damaging surrounding
normal tissue. What's more, when these viruses replicate in the target tumor
cells, the resulting offspring infect other malignant cells.
Some oncolytics are naturally occurring, while others can be genetically engineered. Some examples of natural oncolytic viruses include:
Some oncolytics are naturally occurring, while others can be genetically engineered. Some examples of natural oncolytic viruses include:
- Myxoma virus
- Newcastle Disease Virus (NDV),
- Reovirus
- Seneca Valley virus
Oncolytic viruses that are genetically
engineered include components from viruses such as adenoviruses, Herpes Simplex
Virus (HSV) and poliovirus.
In order for a virus to be considered safe for use as an anti-cancer treatment, scientists look for a number of positive attributes, including:
In order for a virus to be considered safe for use as an anti-cancer treatment, scientists look for a number of positive attributes, including:
- Relatively low ability to produce disease (pathogenicity)
- Ability to replicate in malignant cells
- Easily manipulated genetically
- Ability to be delivered systemically
- Susceptibility to an antiviral drug
Researchers also look for oncolytic viruses
that do not cause serious side effects after they are
administered.
Studies examining the use of viral therapies aren't unique to the 21st century. A 1912 report documents the regression of uterine cervical cancer after a patient was injected with a modified rabies vaccine.
This same attenuated rabies vaccine was also used in 1940 to treat cases of melanoma. And there are several documented reports of lymphoblastic leukemia that waned in the presence of the measles virus.
Several large studies have shown that even the common cold and flu can have a protective effect against developing cancer!
Based on these and other positive results, the Chinese government approved the clinical use of the adenovirus H101 specifically for treating head and neck cancer.
Perhaps other countries will follow suit and approve such viral therapies. In the meantime, several clinical trials are currently underway to continue exploring the anti-cancer benefits of both natural and genetically engineered viruses.
I believe all modified viruses should be rigorously tested for safety, including long-term safety — not the usual FDA criterion that says a treatment is okay if the patient doesn't keel over dead at once. But if higher standards of safety are met, I see no reason to reject a virus that kills only cancer tissue and leaves healthy tissue unharmed.
It's possible that "custom viruses" will be used to do great harm — opening new possibilities for germ warfare. But that can't be helped. Such sick misuses of technology are no reason to reject legitimate uses. I don't believe gene technology can be repressed — the genie can't be put back in the bottle. So we may as well enjoy the benefits while trying to avoid the hazards.
