Adult Stem Cells That Do Not Age



Here is another discovery on the road to mastering the problems of aging and its possible elimination.  Now researchers will have an immortal culture protocol which will surely accelerate work and the flow of fresh discoveries.

More critically it abruptly makes treatment economically possible in a wide range of circumstances.  Just the idea that they can be injected and that they will find their own way to a damaged heart is valuable and now practical.

We are quickly approaching the point were this is well understood as a therapeutic method and it becomes routine. 

The good news continues.

BUFFALO, N.Y. -- Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases.

UB scientists created the new cell lines – named "MSC Universal" – by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell types including bone, cartilage, muscle, fat, and beta-pancreatic islet cells.

The researchers say the breakthrough overcomes a frustrating barrier to progress in the field of regenerative medicine: The difficulty of growing adult stem cells for clinical applications.

Because mesenchymal stem cells have a limited life span in laboratory cultures, scientists and doctors who use the cells in research and treatments must continuously obtain fresh samples from bone marrow donors, a process both expensive and time-consuming. In addition, mesenchymal stem cells from different donors can vary in performance.

The cells that UB researchers modified show no signs of aging in culture, but otherwise appear to function as regular mesenchymal stem cells do – including by conferring therapeutic benefits in an animal study of heart disease. Despite their propensity to proliferate in the laboratory, MSC-Universal cells did not form tumors in animal testing.

"Our stem cell research is application-driven," says Techung Lee, PhD, UB associate professor of biochemistry and biomedical engineering in the School of Medicine and Biomedical Sciences and the School of Engineering and Applied Sciences, who led the project. "If you want to make stem cell therapies feasible, affordable and reproducible, we know you have to overcome a few hurdles. Part of the problem in our health care industry is that you have a treatment, but it often costs too much. In the case of stem cell treatments, isolating stem cells is very expensive. The cells we have engineered grow continuously in the laboratory, which brings down the price of treatments."

UB has applied for a patent to protect Lee's discovery, and the university's Office of Science, Technology Transfer and Economic Outreach (UB STOR) is discussing potential license agreements with companies interested in commercializing MSC-Universal.

Stem cells help regenerate or repair damaged tissues, primarily by releasing growth factors that encourage existing cells in the human body to function and grow.

Lee's ongoing work indicates that this feature makes it feasible to repair tissue damage by injecting mesenchymal stem cells into skeletal muscle, a less invasive procedure than injecting the cells directly into an organ requiring repair. In a rodent model of heart failure, Lee and collaborators showed that intramuscular delivery of mesenchymal stem cells improved heart chamber function and reduced scar tissue formation.

UB STOR commercialization manager Michael Fowler believes MSC-Universal could be key to bringing new regenerative therapies to the market. The modified cells could provide health care professionals and pharmaceutical companies with an unlimited supply of stem cells for therapeutic purposes, Fowler says.

Lee says his research team has generated two lines of MSC-Universal cells: a human line and a porcine line. Using the engineering technique he and colleagues developed, scientists can generate an MSC-Universal line from any donor sample of mesenchymal stem cells, he says.

"I imagine that if these cells become routinely used in the future, one can generate a line from each ethnic group for each gender for people to choose from," Lee says.
The research was funded by the National Institutes of Health and New York State Stem Cell Science (NYSTEM).

The University at Buffalo is a premier research-intensive public university, a flagship institution in the State University of New York system and its largest and most comprehensive campus. UB's more than 28,000 students pursue their academic interests through more than 300 undergraduate, graduate and professional degree programs. Founded in 1846, the University at Buffalo is a member of the Association of American Universities.

Science in the Muslim world Of Asean

The one great theme sold forever about the Muslim world and its history is the idea that it somehow was a cradle of science as policy during a large part of its history.  I find the idea to be an exaggeration.  What is true is that science and mathematics progressed continuously from its initiation in the Greco Roman world through to the present.

Until the advent of the the Scottish enlightenment in particular, this progress rested in the hands of a very few scholars who copied sources and assembled libraries and contributed new work

These scholars were gifted individuals who attracted sponsorship from wealthy patrons.  When there was a shortage of wealthy patrons the scholarship was naturally diminished.  Thus under the Ottomans who were at heart a nomadic people without a scholarly tradition or natural respect, it becomes unsurprising that scholarship languished, though the tradition of patronage continued but in competition with a far more robust Western system.

Salam, who is mentioned here, is merely a late example of such traditions.

Islam captured the entire developed world of its time and place and controlled its wealth.  In the process they monopolized any form of patronage and thus the livelihoods of scholars.  Scholarship advanced largely in spite of this form of civilization rather than because of it.

Great minds are scattered pretty evenly about.  Preparatory education and patrons are not.  Just how many great minds do you think survive the educational niceties of present Islamic education today?

The real breakthrough came with the invention of the modern university concept in eighteenth century Scotland.

Air Strike on Iran Nuclear Assets Possible Now





When I posted two or three weeks ago that an American supported Israeli air strike was possibly eminent because the necessary assets had moved in place, I still lacked the reason as to why just now.  This tells us why it will happen now.  Assume Russia will arrange to be standing by for this one and to also be in the know.  They may be selling a reactor, but they want a nuclear weapon in these fool’s hands no more than we do.  Think of the rich targets for Islam in Russia.

A surgical strike is likely to happen this week.  The purpose will be to smash up the reactor itself.  The only interesting question is how the Iranian air force will be neutralized while the attack goes in, particularly if they wish to have a back up wave.  I assume the US will not be visible.

Iran’s reaction will be of serious interest.  The most damaging thing that they could do in the short term is to suspend oil shipments to the extent that they can.  This could precipitate a jump in oil prices to the $150 mark and generate a sharp decline in stock prices.  That though should be the most effect their actions may have.

In the medium term, regime control of the population will likely spiral out of control because the population will immediately blame the regime for bringing this attack on to themselves.  Discontent is also likely to become visible in the armed forces because of the regime’s reckless behavior and proven futility.  In short, the regime will be destabilized.

Beyond what we have just described, they have no creditable response.

I note from this map that the reactor is on the Persian Gulf itself.    Any attack seems way more difficult and may target the secondary assets instead.  In the event, we have reached a decision point.


John Bolton: Russia's Loading of Nuke Fuel Into Iran Plant Means Aug. 21 Deadline for Israeli Attack

Friday, 13 Aug 2010 01:41 PM
By: David A. Patten


News that Russia will load nuclear fuel rods into an Iranian reactor has touched off a countdown to a point of no return, a deadline by which Israel would have to launch an attack on Iran's Bushehr reactor before it becomes effectively "immune" to any assault, says former Bush administration U.N. Ambassador John R. Bolton. 

Once the fuel rods are loaded, Bolton told Fox News on Friday afternoon, "it makes it essentially immune from attack by Israel. Because once the rods are in the reactor an attack on the reactor risks spreading radiation in the air, and perhaps into the water of the Persian Gulf." 

Russian Prime Minister Vladimir Putin declared in March that Russia would start the Bushehr reactor this summer. But the announcement from a spokesman for Russia's state atomic agency to Reuters Friday sent international diplomats scrambling to head off a crisis. 

The story immediately became front-page news in Israel, which has laid precise plans to carry out an attack on Iran's nuclear facilities while going along with President Obama's plans to use international sanctions and diplomatic persuasion to convince Iran's clerics not to go nuclear. 

Bolton made it clear that it is widely assumed that any Israeli attack on the Bushehr reactor must take place before the reactor is loaded with fuel rods.

"If they're going to do it that's the window that they have," Bolton declared. "Otherwise as I said before, once the rods are in the reactor, if you attack the reactor you're going to open it up and radiation will escape at least into the atmosphere and possibly into the waters of the Persian Gulf.


"So most people think that neither Israel nor the United States, come to that, would attack the reactor after it's been fueled."

Bolton cited the 1981 Israeli attack on Saddam Hussein's Osirak reactor outside Baghdad and the September 2007 Israeli attack on a North Korean reactor being built in Syria. Both of those strikes came before fuel rods were loaded into those reactors.

"So if it's going to happen in Bushehr it has to happen before the fuel rods go in," Bolton said. 

The conversation that touched off the de facto deadline for Israeli military action was a telephone conversation with wire services involving Sergei Novikov, a spokesman for Rosatom, the Russian Energy State Nuclear Corp. 

Novikov said: "The fuel will be loaded on Aug 21. This is the start of the physical launch” of the reactor.

"From that moment the Bushehr plant will be officially considered a nuclear-energy installation," Novikov said, adding that the head of Rosatom, Sergei Kiriyenko, will visit Bushehr Aug. 21 to conduct a ceremony for the event.
According to Bolton, once the reactor is operational, it is only a matter of time before it begins producing plutonium that could be used in a nuclear weapon.

"And in the normal operation of this reactor, in just a fairly short period of time, you could get substantial amounts of plutonium to use as nuclear weapons," Bolton told Fox. 

Russia, which is operating under a $1 billion contract with Iran, has spent more than a decade building the reactor. If Russia moves forward with its plan to fuel the reactor, it could be seen as a major setback to the Obama administration's strategy of engaging Russian leaders in order to win their cooperation.

"The U.S. urged them not to send the Iranian's fuel rods," Bolton said. "They did that. The Obama administration has urged them not to insert the fuel rods in the reactors, but as they've just announced that will begin next week. What that does over time is help Iran get another route to nuclear weapons through the plutonium they could reprocess out of the spent fuel rods."

The developments mean Israeli Prime Minister Benjamin Netanyahu soon may face a stark choice: Attack the Bushehr reactor in the next 8 days, or allow it to become operational despite the certainty it would greatly enhance Iran's ability to create nuclear weapons. 

Russian leaders have said the Bushehr reactor project is being closely monitored by the International Atomic Energy Agency (IAEA), the UN's nuclear watchdog group. According to Iran's ISNA news agency, IAEA inspectors will be on hand to observe the fuel-rod loading process that is now scheduled to begin Aug. 21. 

According to Russian officials, Iran has promised in writing to send all spent fuel rods from Bushehr back to Russia for reprocessing, to ensure they cannot be used for nuclear weapons.


Bolton said the reactor has been "a hole" in American foreign policy for over a decade.

The failure to demand it be shut down began in the Bush years, he said, and continues with the Obama administration "under what I believe is the mistaken theory that Iran is entitled to the peaceful use of nuclear energy."

"I don't think Iran is entitled to that, or I don't think we ought to allow it to happen, because they're manifestly violating any number of obligations under the non-proliferation treaty not to seek nuclear weapons. But this has been a hole in American policy for some number of years, and Iran and Russia are obviously exploiting it," Bolton said.

Russia’s move would put Iran "in a much better position overall," he said, adding, "I think this is a very delicate point, as I say, it closes off to the Israelis one possible target for pre-emptive military action.

U.N. sanctions against Iran, he said, "have not had and will not have any material effect on Iran's push to have deliverable nuclear weapons."

Nerve Regeneration Breakthrough



This is the first real news related to regeneration that is really important.  Stem cell work up to now faced the brick wall of nerve recovery.  Now all folks suffering nerve damage can become nervously optimistic and really look forward to leaving their wheelchairs.

 

Nothing is so important.

 

This also makes it possible to completely regenerate a fresh set of teeth sooner or later.

 

In fact all forms of regeneration now become plausible.  This was merely a dream until a nerve generation protocol arose.

 

So we can legitimately hold out hope to anyone hanging on through major physical damage.

 

In breakthrough, nerve connections are regenerated after spinal cord injury

 

Researchers from UCI, UCSD and Harvard deleted a cell growth inhibitor called PTEN

 

    Irvine, Calif., August 8, 2010 —


Researchers for the first time have induced robust regeneration of nerve connections that control voluntary movement after spinal cord injury, showing the potential for new therapeutic approaches to paralysis and other motor function impairments.

In a study on rodents, the UC Irvine, UC San Diego and Harvard University team achieved this breakthrough by turning back the developmental clock in a molecular pathway critical for the growth of corticospinal tract nerve connections.

They did this by deleting an enzyme called PTEN (a phosphatase and tensin homolog), which controls a molecular pathway called mTOR that is a key regulator of cell growth. PTEN activity is low early during development, allowing cell proliferation. PTEN then turns on when growth is completed, inhibiting mTOR and precluding any ability to regenerate.

Trying to find a way to restore early-developmental-stage cell growth in injured tissue, Zhigang He, a senior neurology researcher at Children’s Hospital Boston and Harvard Medical School, first showed in a 2008 study that blocking PTEN in mice enabled the regeneration of connections from the eye to the brain after optic nerve damage.

He then partnered with Oswald Steward of UCI and Binhai Zheng of UCSD to see if the same approach could promote nerve regeneration in injured spinal cord sites. Results of their study appear online in Nature Neuroscience.

“Until now, such robust nerve regeneration has been impossible in the spinal cord,” said Steward, anatomy & neurobiology professor and director of the Reeve-Irvine Research Center at UCI. “Paralysis and loss of function from spinal cord injury has been considered untreatable, but our discovery points the way toward a potential therapy to induce regeneration of nerve connections following spinal cord injury in people.”

According to Christopher & Dana Reeve Foundation data, about 2 percent of Americans have some form of paralysis resulting from spinal cord injury, which is due primarily to the interruption of connections between the brain and spinal cord.

An injury the size of a grape can lead to complete loss of function below the level of injury. For example, an injury to the neck can cause paralysis of arms and legs, loss of ability to feel below the shoulders, inability to control the bladder and bowel, loss of sexual function, and secondary health risks including susceptibility to urinary tract infections, pressure sores and blood clots due to an inability to move the legs.

“These devastating consequences occur even though the spinal cord below the level of injury is intact,” Steward noted. “All these lost functions could be restored if we could find a way to regenerate the connections that were damaged.”

He and his colleagues are now studying whether the PTEN-deletion treatment leads to actual restoration of motor function in mice with spinal cord injury. Further research will explore the optimal timeframe and drug-delivery system for the therapy.

Kai Liu, Yi Lu, Andrea Tedeschi, Kevin Kyungsuk Park, Duo Jin, Bin Cai, Bengang Xu and Lauren Connolly of Harvard; Jae Lee of UCSD; and Rafer Willenberg and Ilse Sears-Kraxberger of UCI also contributed to the study, which was supported by the Wings for Life Spinal Cord Research Foundation, the Craig H. Neilsen Foundation, the International Spinal Research Trust, the National Institute of Neurological Disorders & Stroke, and a private contribution to the Reeve-Irvine Research Center.

Global Warming - Burning My Iceland

Living on a tropical island, is quite unique. If you love the natural world, there are many things you could do it. I grew up in a small valley in the hills south of my island and I have known my whole life.

Field trips to a pretty fast pace of the canyon hills hundred meters is all worth it when I have to choose a place near the top only. It is a true blessing to be able to do. It is a wonderful job, too. The tops of steep hills to near the base is covered by savannah grasslands. The very steep slopes and along its base are wooded ravine. More than jungle delirium. If you look in the mountains in the distance, are the golden color of the meadows a great contrast to the dark green jungle hills. It is amazing to know how my mind that a hundred years ago, almost all of these dark hills. Jungles all the way up. Wow. And one reason why not.

Fire was a tool for humans used almost since its discovery. He also has done before. And one of the biggest weapons for hunting deer has become here in the jungles of the south. What they do is a fire. Just set a fire the flame and let it rip. Help if you would have difficulties. For once it's gone and burning in arable soil, a wonderful thing called life happens next. New shoots of grass from the hills and burned black. And the deer is probably a surprise, because they consume these tender buds. The wild hunter waits.

Oh, but all the other things that there was kindled a fire in the hills happened. Surely this is not the arsonist would have thought about it. Let us straight in the direction that things go happen. The fire is determined and set on fire. The atmosphere is the first hit. A powerful greenhouse gas (carbon dioxide), a by-product of combustion of vegetation is directly exposed to the atmosphere. But wait. We do not really feel their effects for a long time. No, not right. Global warming. Exactly. It is not surprising that the collective memory of vegetation in the world is still a significant contribution to global warming? his strike.

While in the flames, a fire are often lost in a jungle. The fire will stop, right? That is true. The last time. But the fire will not die once they walk into the jungle. He has to burn its way into a little "to run into the water and most of the jungle. You know, it will take at least one meter. Do burnout. So how can you burn burn, walking to the size of forests . The more you burn, the less the jungle. Strike two.

Now, the fire died and the hills are bare. When the rain comes, and then the soil to wash away. I have never burned washed flee a hill by the rain. Soil erosion by sedimentation in water. But that does not matter. The ocean is big. Will not hurt. In the grand scheme of the oceans, not too much. For aquatic life in rivers, coral, and the open sea populations that feed and live on these reefs, the damage is absolutely fatal. Strike three.

Add all. We have professionals on the one hand, the shot immediately after a new fire is enticing deer. It would be easier to catch. And only useful for the hunter. We are opposite on the other side, and the list is impressive.

- The air in our atmosphere gets an infusion of a potent greenhouse gas that contributes to global warming. We know without doubt that large and persistent global warming has caused and is accelerating, climate change may very well end our day.

- It is the country. Our lower jungle. This quickly leads to loss of habitat for animals. The bright green jungle of our gold and the sea of our savannas are burned from the hills of text and black. All animals, nests or caves caught fire, food, well, that's just their loss. And if it rains, we lose our topsoil. The roots in the city, burned clean. accelerated soil erosion, I despise. .

- It is the sea, rivers are included. Immediately after the soil erosion is the effect of sedimentation. This transported soil spreading. And blankets and suffocates when it finally stabilized. Sedimentation is the bearer of death for microscopic organisms, plants, fish and corals, to say the least. In the aquatic environment, is the destruction of large and extended. Imagine that your air is filled with the ashes of all time. What would be the quality of your life, what then?

He has about 700 million tons of carbon dioxide into the atmosphere every day. There is no doubt, no debate. A large percentage comes from the constant reminder of the natural landscape. We have to change the way they do things.

The survival of our race, have to stop global warming. Climate change in progress should be maintained, if not reversed. If we refuse to realize this, it will matter in fifty or a hundred years? Spread the word. Take part. We can still save.

Proof of Evolution and challenges of global warming


The idea of anthropogenic global warming is under fire in recent months. Those who collect and disseminate information, it was discovered the numbers have changed, so that man is warming seems to be done.

Some of these "scientists" are now conceded that the data shows global warming has not happened since 1995.

Thousands of scientists have provided information that the idea of artificial contradiction with global warming. Only recently has this idea confirmed.It-against has been shown that global warming scientists "have falsified data. This is already accepted.

This reveals the fact that politics can affect the results of some scientists. Ie. Scientists are not all looking for a little 'practice.

Our world, of course, seems to be cooling or heating. This site is for thousands of years. However, until now, there is no evidence that humans are the trends van deze case (solar activity seems to be the TE Meest scientific explanation).

It 's amazing how the idea of man and global warming seems to Darwinian evolution made in parallel with each other.

O data and information was collected mainly in universities and government institutions (this is the fox guarding the hen house?).
or Both make use of ad hominem attacks, like the call of the opposition "flat earthers" or other names.
Opponents or are prohibited by most of the original data. I'm just not allowed much of the information used to support the ideas seen.
o The two have strong support from the media, despite the fact that the scientific evidence against two ideas overhelmingly
or Both are strongly encouraged in public schools and universities.

It is easier to transmit data on global warming to find (even if the data were kept secret years) is that Darwinism Because dealing with the evolution of different aspects of science.
The person is interested in digging beneath the surface of normal university or high school during the next hoaxes (or science just terrible) was used to "prove" the theory of evolution.

or Piltdown Man, a creature with characteristics of both humans and monkeys. Used for four decades, the theory of evolution is to take hold "in the United States until someone discovered that the" monkey-man'was formed by mixing of two monkeys and human bones were found with the bones as they age, filed teeth, etc.
Or Nebraska man was a man-ape of high-profile ", used in the test Sccopes (high profile). It 'very instrumental in establishing the idea of man evolving from apes. Following this" monkey man "was shooting with a single tooth of an extinct pig.
or embryos Haeckel was a chart with various vertebrates that "all steps in the evolution" in its infancy (which is also the same phase of Gill). This image is a hoax at the end of 1800. (Although we still found in many textbooks today).

These hoaxes and bad science are not the exception. There are literally dozens of scientific laws, principles and facts that directly contradict the theory of evolution.

Statist regimes (including Nazism), socialism and communism are all based on the Darwinian theory of evolution (in particular to eliminate the idea of Judaism and Christianity). Their posters often include the theory behind their ideas.

Today it seems that the same people behind the artificial global warming is pushing the idea of evolution.

Unless something beneath the surface of typical hand, we remain convinced of information that educators and politicians for decades teaches us that both ideas.

Politics and science do not mix. And if they do not mix together, always knowing that suffers at the expense of politics. Recent discoveries have shown that the "science of man-made global warming is seriously compromised. With all the facts that we discover the trend, it seems that the same happens with it as well.

For some form of evolution is clear evidence to support the theory, Darwinism is more than likely continue on the same track as the man who took the global warming. It could also last for many decades, however, the current serious problems of evolution to the public.

Why does not Al Gore debate on global warming?

As I write this article, the U.S. is a large explosion in the Arctic. E 'was 40 degrees at Miami Orange Bowl, the coldest ever. Beijing, London, Seoul falls and says other parts of the world under the snow important in their history. And Al Gore, there is a need for a debate on planet Earth. I know I would say that this extreme cold is caused by global warming.

To say that the two basic facts about global warming come. One thing is global warming. And two, the warming caused by man. He said that the 3,000 scientists around the world and all disciplines of climate in 100% agreement on these two issues.

It may surprise you, but I agree with these points. What I can not live without debate position. Who is that Al Gore is he? To begin, it is not even a scientist! If nothing else, you could probably learn a challenge, especially if they are scientific. Heck, I think I can learn a thing or two!

I guess that means that the discovery of new evidence or research, contrary to his position, would not be accepted. I wonder if 3000 scientists could find agreement with this statement? Why spend taxpayer money warming of global research, if it did?

Does Al believe that man is 100% the cause of global warming? Here I request the data. I read enough science to know that millions of years the Earth was covered with ice. to melt a massive global warming and that man was not there. Scientists tell us that the main causes of submarine volcanoes and the sun, I think the sun and volcanic eruptions are an important part of global warming? I want to hear the percentage of debate. I wonder if it would do more for the environment and put a sock in the mouth of the volcano to another or in the mouth?

To say that we go to the disaster in the coming decades. I have heard of freshwater and coastal areas, but what about Chicago. I have neighbors who do not just "warm up have been here. Again, I'm not ready to see the disaster in the future and sees his friends. In the U.S., we have seen cooler temperatures of this decade (it is the Convention on growth Copenhagen climate change by the United Nations), but the carbon emissions of more people. What is the science of climate around this? Then these data suggest at least a period of a catastrophe?

All must agree that no study of personal preferences or policies on global warming. He was able to obtain an objective attitude in the treatment of all data completely. We assume that each insured of his advisers, he knew all the possible interpretations of the abuse. There are other models or scenarios that can be accepted. The Admit it, you can not discuss because they would be exposed as a fraudster. Remember, this is the same man who gave us several versions of Al Gore in his presidential race.

To have enough money to support the global warming of his family for generations. No descendant of Al Gore will never work. Instead his mantra of "no more debate, I would like to hear" no more dollars "! What about the commitment of all to all the money he makes of global warming on the poorest countries in Africa to make.
