Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
According to the National Institutes of Health article “Can Stem Cells Repair a Damaged Heart?”, “Researchers now know that under highly specific growth conditions in laboratory culture dishes, stem cells can be coaxed into developing as new cardiomyocytes and vascular endothelial cells. Scientists are interested in exploiting this ability to provide replacement tissue for the damaged heart. This approach has immense advantages over heart transplant, particularly in light of the paucity of donor hearts available to meet current transplantation needs.”
The inventors describe their device within their patient application: “A biologic ventricular assist device that also has the capability to capture, grow, and administer stem cells to regenerate and restore damaged myocardium in the heart. The device works in conjunction with a traditional ventricular assist device and possesses an additional external path or tube that is in-line with the path of the ventricular assist device."
They continue, "The external path allows for the administration of stem cells, genes, genetically modified cells or other therapeutic biologic or pharmacologic agents, as well as leading to a stem cell collecting accessory … that captures circulating stem cells.”
Although the cardiac stem cells cannot totally repair the ailing heart, they do have the ability to repair it enough so that the VAD can be eventually removed from the body.
Then, the partially repaired natural heart can take over the circulation of blood within the human body, and perform the job until a transplant of another heart is available.
