Aging: The continuous process from birth to death
...uced body mass reductions accounted for changes in vertebral structural properties, but the alterations in tibial structural properties were independent of body mass. Thus, the researchers conclude that caloric restriction adversely and differently influenced axial and appendicular bones in late-middle-aged an...New species of earliest-known salamanders found in China
...etail, Shubin said. The fossil also shows that the vertebral column and the limbs are not yet formed, and that the animals internal gills remain. Salamanders are living fossils -- they have retained the same body plan for millions of years.

... of the six base changes was associated with lower vertebral bone density in the lumbar region. "If you look at the population, if people ever form a stone, theyre probably at greater risk of bone loss or osteoporosis," Gitomer said.

Turning to the molecular effects of this polymorphism, they show that, at least in cultured human osteoblasts, the s allele generates higher steady state l...Scientists selectively activate "cell rescue" pathway in bone cells

Though widely known as a disease that affects women, osteoporosis is responsiblefor bone fractures in as many as 25 percent of men over the age of 60. Almost 50percent of women over 60 suffer fractures from the disease....... notochord, a rod-like structure that precedes the vertebral column in vertebrate embryos, signals neural cells to induce the formation of floorplate, a crucial row of cells that lies along the floor of the ventralbrain and spinal cord. This belief has come under fire recently, as new data about floor plate de......Hengst looked at how the ribs were attached to the vertebral column to determine the efficiency of the respiratory systems in a number of carnivorous theropods, a class of flesh-eating dinosaurs that walked mainly on their hind legs and included Tyrannosaurus rex.
