That way their treatments might stand a better chance of arresting the degenerative process before disability sets in. Unfortunately, conventional X rays, which give very detailed pictures of bone, don't provide very good images of cartilage. And researchers haven't yet discovered any biological markers in the blood that reliably tell them, "Hey, this person's cartilage is starting to fall apart. Do something...
Some of the evidence for this comes from related research on bones. Most people think of bones as inert objects whose only job is to keep our bodies from collapsing into a puddle of flesh. But bones are actually quite active tissues, constantly building and rebuilding themselves from the inside out. Anytime you break a bone, the body produces repair proteins that direct cellular activities as the bone knits itself together. When investigators take these so-called osteogenic proteins and sprinkle them on laboratory samples of damaged cartilage, the cartilage begins to repair itself...
...chance that potential donors will actually go on to donate is about 25 to 30 percent, said drive coordinator Adrienne Harrison. That will happen if a student’s HLA type—the type of tissue needed by bone marrow patients—matches that of a patient listed in the registry...
...bone marrow drive is not really like a blood drive because we’re not looking for quantity, such as a certain number of people to donate a certain amount of blood, but for a good quality donor,” Herrmann said. “We need donors who will stay committed, keep in touch and follow through...
Previous studies have shown that higher levels of physical activity increase bone density in elderly women, but no study had examined the relationship between walking and risk of hip fractures, said Professor of Medicine Graham A. Colditz, one of the study’s three primary authors...
