Disorders related to the intervertebral disc (IVD) are common causes of morbidity and of severe life quality deterioration. IVD degeneration, although in many cases asymptomatic, is often the origin of painful neck and back diseases. In Western societies IVD related pain and disability account for enormous health care costs as a result of work absenteeism and thus lost production, disability benefits, medical and insurance expenses. Although only a small percentage of patients with disc disorders finally will undergo surgery, spinal surgery has been one of the fastest growing disciplines in the musculoskeletal field in recent years. Nevertheless, current treatment options are still a matter of controversial discussion. In particular, they hardly can restore normal spine biomechanics and prevent degeneration of adjacent tissues. While degeneration affects all areas of the IVD, the most constant and noticeable changes occur in the gel-like central part, the nucleus pulposus (NP). Recent emphasis has therefore been put in biological ways to regenerate the NP; however, there are a number of obstacles to overcome, considering the exceptional biological and biomechanical environment of this tissue. Different biological approaches such as molecular, gene, and cell based therapies have been investigated and have shown promising results in both in vitro and in vivo studies. Nonetheless, considerable hurdles still exist in their application for IVD regeneration in human patients. The choice of the cells and the choice of the cell carrier suitable for implantation pose major challenges for research and development activities. This lecture recapitulates the basics of IVD structure, function, and degeneration mechanisms. The first part reviews the recent progress in the field of disc and stem cell based regenerative approaches. In the second part, most appropriate biomaterials that have been evaluated as cell or molecule carrier to cope with degenerative disc disease are outlined. The potential and limitations of cell- and biomaterial-based treatment strategies and perspectives for future clinical applications are discussed.

When Leslie Harper decided to become a resident of the Palm Beach Palace Hotel in Palm Beach, Florida, she had no idea how her life would change. Leslie Harper had lost her husband, and soon she found that her big house was too large for one person. She decided to look into the Palm Beach Palace, a hotel catering mostly to seniors, which she had passed many times but had never entered. She made an appointment to see what it was like and how much she really liked the idea of being with people who, like herself, wanted their privacy. But when she wanted the pleasure of being with other people, then she was ready to mix with company. She entered the building and found it to be what she expected. It would be quite manageable. And she knew that if she wanted to be private, she could retreat to her apartment. On the other hand, if she wanted to be with people, she could go downstairs and see others like herself, where she could carry on with the other residents. So she signed a year’s lease. As soon as she packed her belongings and moved in, she found that she had done the right thing. Yes, indeed, she had done the right thing.

Mrs. King has here abstracted the earliest wills of 38 Kentucky counties formed between the years 1780 and 1842 (with the exception of Crittenden County) and representing the state as a whole. The information given includes dates of instrument and probate, names of wife and children, and names of witnesses. The arrangement is county by county, each with its own index, with a general index at the rear of the book containing all the names mentioned in the text. The following Kentucky counties are within the scope of the work: Barren, Bourbon, Bullitt, Caldwell, Christian, Clark, Crittenden, Daviess, Fayette, Franklin, Gallatin, Garrard, Greene, Hardin, Harrison, Henderson, Henry, Hopkins, Jefferson, Jessamine, Knox, Lincoln, Livingston, Logan, Madison, McCracken, Mercer, Muhlenberg, Nelson, Nicholas, Ohio, Scott, Shelby, Spencer, Todd, Warren, Washington, and Woodford..
