From wheel chair to walk again
William Orr hasn’t always been in that wheelchair, 24 years ago he survived a tragic accident while riding his bike, leaving him paralyzed from the waist down. Today, he speaks with high hopes, optimism, and an emotional strength he will one day walk again, thanks to a Bonita Springs doctor.
Bill Orr is not quite walking. But he’s getting close. And his progress may be one of the best stories of 2010 for a whole lot of reasons.
The 50-year-old Aurora man has been a quadriplegic for half his life —
A new method to reprogram adult cells making them similar to stem cells has been discovered. The key protein in the discovery is Wnt, already known to scientists for its involvement in numerous phases of development in vertebrates and invertebrates. The study, conducted by the Telethon Institute of Genetics and Medicine (TIGEM) in Naples by Maria Pia Cosma, was published in the online version of Cell Stem Cell magazine. The study involved various types of adult cells including fibroblasts, thymus cells, and neural precursor cells, which were fused with embryonic stem cells in the presence of the
All those who have suffered ligament damage could benefit from artificial ligaments built biologically. But, experimentation on artificial ligaments, which could come from stem cells and naturally replace damaged tissue, will not continue. Speaking about the issue was Luigi Ambrosio, one of the researchers of the Institute of Technology of Composite Material of the National Research Council (CNR) in Naples, who contributed to the realization of this biological ligament. Two solutions were proposed by the Neapolitan laboratory.
One solution was to build a biodegradable structure out of hyaluronic acid, one of the components of ligament
