Embryonic stem cell therapy shows steady benefits in rebuilding infarcted heart
...tronger than the sham-treated group, but the heart beat of the stem-cell group reacted favorably to "stress test," whereas the sham group showed no significant response at all. Like all the other parameters, these improvements were maintained over the three-month length of the study. On pathology, furthe...Embryonic stem cell - based tissue engineering may help repair damaged heart muscle
...muscle cells die off. Eventually it is too weak to beat properly." With the integration of the human embryonic stem cells and their patented supporting framework, Kofidis hopes that they have the two pieces of the puzzle needed to successfully integrate regenerative cells into the damaged heart, maintain ...Motion that powers sperm provides key to unravelling rare genetic disorder
...type of cilium which is much more common but don't beat together, serves to sense the environment surrounding the cell. If these key cellular function breakdown there can be a huge knock-on effect on normal running of the cell.

The most common citrus PMFs, tangeretin and nobiletin, are found in the peels of tangerines and oranges. The...'Cardiofunk' mutation: Probable source of congenital heart defects
The human heart confounds logic by starting to beat before it is fully formed -- a developmental oddity shared by all vertebrate hearts. New research now reveals a related oddity: The valve needed for the heart to pump out blood won' t form normally unless the heart is already steadily beating. The su...Jefferson scientists use gene therapy to restore function of damaged heart cells in lab

"If you can't beat them -- and you can't -- then you want to indulge them," says John Alverdy, M.D., associate professor of surgery at the University of Chicago and director of the study.
