Though their relative abundances in any given fossil bone are extremely variable, statistically significant Fisher's Exact tests found that if a bone yields one of these types of microstructures in abundance then the others are usually also abundant. (lu.se)

Osteoporosis is a crippling bone condition that develops when the body cannot produce enough bone or loses too much bone, weakening the bones and making the person susceptible to serious bone damage or breakage. (theexpresswire.com)
The escalating incidence of osteoporosis has prompted the creation of cutting-edge techniques for bone repair and reconstruction. (theexpresswire.com)
In my last bone scan my osteoporosis actually improved. (heartandsoil.co)
