Atomic minerals are the smallest components of bone and the content of Ca, being the most abundant mineral in bone, correlates strongly with the risk of osteoporosis. Postmenopausal women have a far greater risk of suffering from OP due to low Ca concentrations in their bones and this is associated with low bone mass and higher bone fracture rates. However, bone strength is determined not only ...
Bones are formed from a combination of collagen and minerals, primarily calcium and phosphate salts. One of the cells in bone is the osteoclast that resorb (i.e., remove) preexisting bone, a process essential for bone development and adaptability. This cell belongs to the macrophage lineage of cells, and has its origin in the marrow. In diseases such as osteoporosis, the healthy balance of adul...
A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in...
The new approaches of the animal production systems make managing the mineral nutrition a challenge. Versus the excessive, trace mineral supply in intensively managed livestock, well above the physiological requirements, is the no trace mineral supplementation of organic systems, which become highly dependent on trace minerals in the soil. Nowadays, in addition to the animal health perspective,...
This article illustrates the importance of having analytical data on the vitamin and mineral contents of dietary supplements in nutrition studies, and describes efforts to develop an analytically validated dietary supplement ingredient database (DSID) by a consortium of federal agencies in the USA. Preliminary studies of multivitamin mineral supplements marketed in the USA that were analyzed as...
Every animal has a skeleton made up of many different bones. Bones are vital. Without bones we would not be able to move, protect our internal organs, store important minerals, or even make some cell types! When young, in addition growing, must develop into specific shapes. This article describes how and why grow heal humans guinea pigs. Using special imaging technique called micro-computed tom...
