SCIENCE CONTIUALLY FINDING OUT HUMAN BODY HAS SELF-REGENERATIVE CAPABILITY....

It is only recently that scientists found that cells can self-regenerate in the human body which turned on its head the old theory that cells in brain die continuously without replacement...

Now the scientists have discovered that the human body regenerates heart cells at a rate of about 1% a year....once again negating the previous knowledge that heart muscle usually simply forms scar tissue after damage and never fully regenerates.

This news is published here on this PVAF knowledge-sharing website because this new discovery is another confirmation how the current humanity through its continual science research in the last 500 years is once again/em> striding towards the total science knowledge that exist in vED, the complete sciences of life and creation...

As per the extant sNskRUt language texts of puraaAN....vED  designs, creates, sustains and cyclically recreates life not only in the universe we live but in infinite number of universes that gets continually created by the Creator using vED and absorbed back in the Creator using VED.....


Talking about the human body, the world famous Dr. Deepak Chopra has said that the human body is the greatest pharmacy on this planet earth and thus can cure any diseases by itself....

Dr Chopra's belief appears to stem from this medical knowledge of current science supplemented by his inherent genetic bias towards vED sciences knowledge.....as can be seen from his sharing of life knowledge in his 25 or so books to date....

PVAF has published many news such as today's to link the relationship between vED knowledge which has gone dormant and currently sciences evolving towards vED....with invitation for YOUR contribution to share such knowledge....

Heart can regenerate cells: br /> ffinds Sweden study
 
Canadian Globe & Mail: April 3, 2009: Kylie MacLellan, Reuters

London - Scientists said on Thursday they had shown the human body regenerates heart cells at a rate of about 1% a year, a discovery that could one day reduce the need for transplants. br />
The study of 50 volunteers, using a dating method that detects traces of a carbon isotope left by Cold War nuclear bomb tests, raises the prospect of artificially stimulating the renewal process some day, they reported in the journal Science.

&"It would be a way to try and help the heart to some self-help rather than transplanting new cells," Jonas Frisen of Sweden's Karolinska Institute said in a telephone interview.

"Taking advantage of the heart's own capacity to generate new cells either using pharmaceutical compounds or, if it is possible, by exercise or any other environmental factor." br />
Heart cells are unusual in that they stop dividing early in life.

Doctors knew there were master cells called stem cells in the heart, but heart muscle usually simply forms scar tissue after damage and never fully regenerates.

In their four-year study, Frisen and colleagues employed an ingenious method to find out whether there is any regeneration at all.

"So at any given time your heart is a mosaic of cells you carry with you from birth and cells that that have been added later to replace cells that have been lost during life."








The finding could also help scientists determine whether some people are predisposed to heart disease, by looking at the heart's ability to renew cells.

"We are interested in studying whether some heart diseases could potentially be caused by too low an ability to replace heart cells," Frisen added.

'Your heart is a mosaic of cells'

"The DNA of all plant and animal cells incorporated high concentrations of carbon-14 released into the atmosphere by above-ground nuclear testing during the Cold War, and this unfortunate episode provides a unique opportunity to test cell population dynamics in human tissues," Charles Murry of the University of Washington and Richard Lee of Harvard Medical School wrote in a commentary.

Carbon-14 dating showed that overall, the hearts of their 50 volunteers were "younger" than the patients' ages.

Frisen said the rate at which the new cells are produced slows as we get older, with a young adult in their twenties renewing cells at a rate of about 1% a year, falling to half a percent a year by the age of 75.

"If you exchange cells at this rate it means that even if you live a very long life you will not have exchanged more than 50% of your cells," said Frisen.
