Don't think so - those researchers had to find the virus preserved in tissues of those buried in permafrost. So, unless those memorabilia have been stored in a freezer - not likely - I think the air, light and time in normal storage would have rendered any virus particles safe, IOW - dead.

Freezing stuff, living stuff, like foods and tissues and other living cells seems to preserve them indefinitely. While heat and normal everyday conditions does the exact opposite. I don't know why just that it does.

Generally good reply about most viruses. They are a portion of RNA [half of the DNA molecule] and have the ability to inject themselves into cells and in effect force the cell to then replicate more viruses in place of normal cellular activity. They tend to exist in hosts or for relatively short time frames outside of hosts and some are more persistent then others. That is why colds can be spread with contact on mucus membranes often through touch but even with someone sneezing on you and tiny particulate matter from the ejecta lodging on your eye or sinus membrane, etc. HIV is tougher to spread and needs to be in body fluid and then transferred to another’s body fluid. Can't get it from the proverbial door knob. Usually blood to blood. That is why once a virus like smallpox is eradicated it may actually be gone from the world stage unless intentionally preserved in cold storage as you stated which is exactly what was done, and how Saddam came by via our intermediaries in '84.

A more interesting and quite dangerous and persistent pathogen is the spongiform for mad cow disease, a prion. One of the most simple and tenacious life forms on our planet. That puppy can exist in the most harsh environments for up to 10,000 years and be unaffected by its lodging awaiting opportunity to enter an available life form and weave its spell. That is why cooking, even well done and drinking strong alcohol with meals or even soaking the meat in it before hand basically has no effect on the prion, nor does sun or wind or rain. One resilient MF'er. Be grateful they are not on the memorabilia from 1918/19's viral outbreak.

Good job of listing some interesting articles and the need for companies to research cures and controls.

Virus may represent the single most dangerous threat and challenge to life on Earth, though as with all life forms ultimately it too is a part of our evolutionary balancing act. Pox virus is one of the most common around and basically has served to be a governor on over population for birds and animals and perhaps insects as well, not sure there. Smallpox is simply a specific virus that affects humans and generally needs a large high density population to take hold, hence the reason for massive outbreaks in urban regions. Spreads easily and takes off quickly with high density populations... Hence over population facilitates natural virus mutations to take hold when they mutate in a way that is beneficial to the virus gaining access to a new population of hosts. These occur all the time as adaptation to their environment. A large dense population of any creature susceptible to a virus potentially allows the virus to take hold more readily then very sparse populations that literally don’t lend a bridge to other hosts and hence can/do die out when other susceptible hosts are not around.

I hope that helps the poster with the old stuff. Not a problem at all. An aside. Those surgical masks that some old photos showed from the 1918/19 outbreak did absolutely nothing. They were like putting a huge fish net over your face, way to porous to stop the tiny virus. But is may have stimulated the immune system with the positive belief that you were doing something very helpful, the placebo effect.

Yes, helps with understaning. Thanks.

What I would like to see is the development of meds/drugs for cancer that protect the healthy cells as noted in previous message here.

Have a friend just diagnosed with lung cancer after surgery and biopsy-----doctors giving mixed opinions-----this is the same as Dana Reeves had. One doc wants to treat with a med that is in trials that protects the healthy cells and then boost with chemo periodically to target the cancerous cells. Another wants to be agressive with the heavy duty chemo.

Having seen a lot of friends of all ages go through various cancers without success, can see the need for something other than chemo.

Pretty heavy stuff to consider.

RNAi works in monkeys

Apparent absence of toxicity and persistence of silencing may bode well for humans

[Published 27th March 2006 05:52 PM GMT]

A disease-causing gene was silenced in monkeys through RNA interference (RNAi) therapy delivered into the bloodstream, scientists reported online yesterday (March 26) in Nature. This is the first study to show that systemic administration of RNAi works in non-human primates, and the findings affirm the promise of this new type of therapy, scientists say.

In the study, gene silencing using the highest dose persisted for 11 days, without any observed toxicity, a finding that "bodes well for future human systemic trials of RNAi therapies," John Rossi of the Beckman Research Institute of the City of Hope in Duarte, Calif., who did not participate in this study, told The Scientist.

Scientists at Alnylam Pharmaceuticals and Protiva Biotherapeutics gave cynomolgus monkeys a single injection of small interfering RNAs (siRNAs) against the gene for apolipoprotein B (ApoB). This gene is involved in the assembly and secretion of low-density lipoprotein (LDL), and has not proven accessible to targeting with conventional small molecule or protein therapies. The researchers encapsulated the siRNAs in a liposomal formulation designed to target the liver, and modified their backbones to prevent siRNA degradation.

Gene silencing occurred in a dose-dependent manner. Within 48 hours, the maximum level of APOB silencing exceeded 90%, with a more than 75% reduction in plasma ApoB and a more than 80% drop in LDL. The researchers detected no reductions with empty liposomes or those containing mismatched siRNA.

Using 5' rapid amplification of cDNA ends (RACE) analysis, the scientists confirmed that silencing occurred via APOB mRNA cleavage at precisely the predicted site. APOB mRNA levels were substantially reduced for at least 11 days -- a silencing effect far more persistent than results previously obtained with rodents, which suggested APOB mRNA levels would recover within four to seven days. Alnylam president and chief executive officer John Maraganore said that metabolic differences between rodents and primates may explain why silencing persisted longer in this study.

The researchers saw no evidence of toxicity, such as pro-inflammatory cytokine production, a finding Maraganore attributed to in vitro toxicity screening beforehand and to the siRNA backbone modifications. The only detected change was a fleeting increase in liver enzymes in monkeys that received the high dose of the liposome-encased anti-APOB siRNAs, which peaked 48 hours after treatment and varied highly across individual animals. These effects normalized by the sixth day, and did not interfere with biological efficacy.

The researchers ended their study after 11 days because "the durability of the silencing far exceeded what we expected," Maraganore told The Scientist. They plan to continue longer-term experiments in primates, and improve the liposome formulations. Still, Maraganore said he believes they are ready for human clinical trials within the next 18 to 24 months.

However, scientists cautioned many details of the therapy should be investigated further. "The data is all from a single dosing, and it is going to be important to determine what happens after multiple dosing, as will be required for chronic liver problems," Rossi cautioned. While the liposome vectors the researchers used are most effective in delivery to the liver, they could also investigate whether the liposomes can deliver siRNAs to different targets, such as the kidneys or lungs, Rossi added.

Investigations should also tease apart how necessary the backbone modifications are to the therapy's effectiveness, Martin Woodle at RNAi therapeutic company Intradigm in Rockville, Md., who did not participate in this study, told The Scientist. "Nanoparticle and liposomal systems are now quite well accepted and very successful, without invoking the need for chemical modifications of the siRNAs themselves," he said. Future research should also investigate whether systemic delivery localizes siRNAs selectively to the liver, or if the silencer reaches other organs, as well, Woodle added.

Here's anudder 1 dat's thinx dey got da answer:

eFoodSafety.com, Inc. Completes Bird Flu Formulation; EFSF Believes It Has Formulated the 'Total Solution' to the Potential Bird Flu Pandemic
Patricia Gruden, President/CEO of eFoodSafety.com, Inc. (OTCBB:EFSF), announced today that eFoodSafety.com, Inc. has completed its product formulations on what it calls the "Total Solution" to the potential Bird Flu pandemic. eFoodSafety's Citroxin formulation has definitively proven in independent laboratory testing to eliminate the H9N2 virus, which is the surrogate organism used in all laboratory testing for the Bird Flu, on both hard and porous surfaces.

eFoodSafety's Citroxin formulation can be sprayed on bird cages and hen houses without it being harmful to animals or humans in surrounding areas if ingested.

Humans who have contracted the H5N1 virus, commonly known as Bird Flu, can rely on eFoodSafety's Citroxin O2 formulation, an ingestible product that the company believes will prove to have dramatic effects on the Bird Flu virus. The Citroxin O2 formulation is currently undergoing human clinical trials on the Influenza Viruses A and B, however testimonials from humans who have taken the product with influenza-like symptoms indicate very promising results.

The company further reports that interest in the Citroxin formulations from large multi-billion dollar pharmaceutical corporations has been very encouraging and anticipates pursuing all opportunities presented.

"It is eFoodSafety's contention that these two products can prevent the spread and effectively treat the potential pandemic Bird Flu virus. We anticipate the product will soon be ready for mass production and distribution," stated Mrs. Gruden.

Vaccine against bird flu

Tuesday, 28th March 2006, 07:39
Category: Healthy Living

LIFE STYLE EXTRA (UK) - SCIENTISTS have created a vaccine against bird flu using horse antibodies.

The Chinese researchers managed to cure mice after infecting them with the killer H5N1 virus.

They discovered the antibodies - derived from horses - prevented the animals from dying.

The study published in the journal Respiratory Research showed a dose of 1O,OOOth of a gram of the horse anti-serum effectively protected the infected mice.

The scientists hope the anti-H5N1 antibodies developed in horses could potentially be used to save dying human bird flu victims or as early treatment for the disease.

Dr Jiahai Lu, of Sun Yat-Sen University in Guangzhou, China, and colleagues infected dog kidney cells in the lab with a lethal dose of H5N1 and simultaneously exposed the
cells to horse antibodies against H5N1.

The cells simultaneously infected with H5N1 and exposed to horse antibodies did not die.

The scientists then injected horse antibodies into 40 mice that had been
infected with a lethal dose of H5N1 24 hours earlier.

They also injected horse serum without H5N1 antibodies into a group of mice that acted as controls.

The researchers found 5,OOOth of a gram of antibody protected 70% of the mice
against death from bird flu and double the dose protected all the animals.

But the mice in the comparison group died nine hours after receiving the normal horse serum that did not contain the H5N1 antibodies.

Public health expert Dr Jiahai Lu said: "Until we have an efficacious vaccine, specific anti-H5N1 agents and effective epidemiologic control measures for H5N1 virus infection, highly mpathogenic H5N1 virus is likely to be a major health threat tto the world."

He said the vaccine could potentially be used for the early treatment of bird flu patients to reduce the severity of illness and the likelihood of passing on the virus to others.

The research had provided "experimental support" for using the vaccine in future large primate or human trials, said Dr Jiahai Lu.

The Worrier
At the U.N.: This Virus Has an Expert 'Quite Scared'

By DONALD G. McNEIL Jr.
Published: March 28, 2006

Dr. David Nabarro, chief avian flu coordinator for the United Nations, has become gun-shy about making predictions — in particular about if and when the A(H5N1) virus, now devastating bird populations around the world, will do the same to humans.

But Dr. Nabarro describes himself as "quite scared," especially since the disease has broken out of Asia and reached birds in Africa, Europe and India much faster than he expected it to.

"That rampant, explosive spread," he said, "and the dramatic way it's killing poultry so rapidly suggests that we've got a very beastly virus in our midst."

Dr. Nabarro, the former chief of crisis response for the World Health Organization, admits that he has been accused before of being an alarmist.

On his first day in his current job, he was quoted as saying the avian flu could kill 150 million people.

In December 2004, when he was in charge of the health organization's response to the Indian Ocean tsunami, he warned that if help did not arrive quickly, cholera and malaria could kill twice as many people as the waves had just swept away.

In Darfur the same year, he said that 10,000 people a month were dying in refugee camps because the Sudanese government was rebuffing aid.

And earlier that year, he warned that Israeli roadblocks were endangering Palestinians who needed drugs for diabetes and high blood pressure.

Asked to reflect on those warnings, he answers: About Darfur, he was dead right. On the Palestinians, he was also right, but massive infusions of aid kept death rates down. On the tsunami, he said, he made his dire forecast when only 40,000 people — not 300,000 — were believed dead, and the world's abundant generosity paid for the clean water and mosquito control that prevented the worst from coming true.

On avian flu, he notes, he predicted 5 million to 150 million deaths — the same range the World Bank was using — but headline writers quoted only the higher figure.

And how many does he now say could die? "I don't know," he said. "Nobody knows."

But he repeatedly said that he is more scared than he was when he took the job in September. In October, he predicted that the virus would reach Africa, where surveillance is so poor that deaths of chickens or humans could easily go undiagnosed for weeks. Last month, he was proved right.

The infection of millions more birds in many more countries "has led to an exponential increase of the load of virus in the world," he said. And influenza is a fast-mutating virus. Each infected bird and person is actually awash in minutely different strains, and it takes lengthy genetic testing to sequence each one — so if a pandemic strain were to appear, "it might be quite difficult for us to pick up that change when it happens."

To skeptics who doubt that the A(H5N1) strain will become a threat to humans because it has existed for 10 years without doing so, he counters that it had the same 10 years to move out of Southeast Asia but did not until last year, when it shot across half the globe.

The skepticism reminds him of his stint in East Africa in the 1980's. No one realized then how widespread the AIDS virus was, and it was still unclear whether it was transmitted by sex. Some experts argued that sex was such an inefficient method of disease transmission that it would never be much of a threat. It has now killed 20 million people, and 40 million more are infected.

"We failed to give it the proper focus, right at the beginning," he said.

Like early AIDS, he said, avian flu has too many unanswered questions, like: Why did the disease, after years of smoldering in poultry, suddenly start hitchhiking in migratory birds? Why does the northern China strain — the one now spreading westward — turn up so many false negatives in diagnostic tests? Why did so many people fall sick so quickly in Turkey?

"Bits of the puzzle are missing," he said. "In six months, will we be cursing ourselves for missing some key phenomena now?"

He fears that the virus will soon be endemic in birds everywhere, rendering containment fruitless and condemning the world to mounting a perpetual vigil for human outbreaks. Its movement into cats frightens him even more because humans routinely curl up with them.

Mutations making it less lethal to humans may, paradoxically, be bad news, he said. A disease that kills half of those it infects often burns out before it reaches new victims, while one that leaves 98 percent of its victims alive, as the 1918 flu did, rapidly reaches hundreds of millions because it has so many carriers.

As a public-health bureaucrat, the 56-year-old Dr. Nabarro, who is British, wants to come across as "honest, accurate, down-to-earth, someone who can translate complex facts in a way that makes emotional sense to those receiving them."

Still, there is something about his voice. Experience has made him wary of misquotation, so he chooses his words as carefully as a surgeon picks through his tray of instruments. But his enunciation is chilling — reminiscent of Basil Rathbone as Sherlock Holmes, describing with slow, awful precision how a body was mutilated.

Even his lighthearted similes come across that way. An Oxford graduate and the son of a prominent doctor, he knows the value of a yard chicken because he has worked in Nepal, northern Iraq and East Africa fighting malaria and malnutrition.

Skip to next paragraph
On the Front: A Pandemic is Worrisome but 'Unlikely' (March 28, 2006) Each bird that lays eggs until it ends up in the pot, he said, "is a short-term savings account with a high rate of growth and a yield that no bank can match."

Culling ruins third world farmers the same way canceling Social Security would devastate the American working class. It forces the poor to hide their flocks and thus protect the virus.

Dr. Nabarro rejects "gloomy" as a description of his outlook, but if he were an oncologist, his patients would flee.

He works out of rented United Nations offices in the Chrysler Building in Manhattan and spends much of his time traveling. But if human spread of the disease starts, that will end abruptly. There will be, he predicted, a "period of wonderment," while authorities figure out whether the first cases are real, then borders will close, airports will shut down, and travelers everywhere will be stranded.

"Assuming I'm here," he said, "I'll just camp down, probably in the Secretariat, and stay there for 6 to 10 weeks."

That means he will not be with his wife and five children, who are still in Switzerland, where he was posted with the health organization, or in college in England. He has not stockpiled Tamiflu for them or for himself, he said — though he does carry a box of it to show at meetings. They, too, will have to hunker down where they are.

"But they know the job I'm doing," he said. "They see me as I'm plotting the virus on maps."

The one aspect of his job that makes him more optimistic is that the world is waking up. In January, Dr. Nabarro went to a summit in Beijing hoping to raise $1.2 billion for the fight. He got $1.9 billion.

Still, that is just a beginning, he said.

"We spend billions to protect ourselves from threats that may not exist, from missiles, bombs and human combatants," he said. "But pathogens from the animal kingdom are something against which we are appallingly badly protected, and our investment in pandemic insurance is minute."

Link Between Skin Cancer and Common Virus

Reported by Kerry Grens on Monday, March 27, 2006.

It’s expected that one million Americans will develop skin cancer this year.

Sun is thought to be the major cause, but other risk factors—like genes and fair skin—can come in to play.

Researchers at Dartmouth College have uncovered another possible contributor.

It is a virus that causes cervical cancer and if researchers can show that it causes skin cancer too, a new world of prevention could open up.

New Hampshire Public Radio’s Kerry Grens has more.
