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...

...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. Whether you look at a salamander you find under a rock in the local fo...

Researchers link gene with kidney stones, bone loss in patients who absorb too much calcium
... 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. Pak, who led the development of Citracal, an over-the-counter calcium citrate...

bodies. This suggests that while the back part ...
Collagen and osteoporosis
...genotype predicts a nearly twofold greater risk of vertebral
fractures relative to SS homozygotes, with Ss heterozygotes experiencing intermediate effects. 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
...uding 300,000 hip fractures, approximately 700,000 vertebral
(spinal) fractures, 250,000 wrist fractures, and more than 300,000 fractures at other sites. In addition to hormone replacement therapy, exercise and adequate intake of calcium and vitamin D can help preserve bone mass and prevent or slow osteoporosi...

fractures due to osteoporosis. 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....
Evidence Mounts Against Maintstream Dogma In Embryology, Could Shed New Light On
... 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...
Purdue Study Finds Prehistoric Couch Potato

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. By analyzing how the ribs pivoted around two p...
