Normal bone remodelling requires the coordinated regulation of the genesis and activity of
osteoblast and osteoclast lineages. Any interference with these integrated cellular systems …

A hypothesis is presented based on a coalescence of anthropological estimations of Homo
sapiens' phenotypes in the Late Paleolithic era 10,000 years ago, with Darwinian natural …

Nitric oxide (NO) is a free radical which has important effects on bone cell function. The
endothelial isoform of nitric oxide synthase (eNOS) is widely expressed in bone on a …

Calcium ion is an essential structural component of the skeleton. There is growing evidence
for the importance of nutrition in the maintenance of bones and joints health. Nutritional …

The nature of the stimulus sensed by bone cells during mechanical usage has not yet been
determined. Because nitric oxide (NO) and prostaglandin (PG) production appear to be …

Nitric oxide (NO) is a pleiotropic signaling molecule that is produced by bone cells
constitutively and in response to diverse stimuli such as proinflammatory cytokines …

Bone loss occurs as a consequence of exposure to microgravity. Using the hindlimb-
unloaded rat to model spaceflight, this study had as its purpose to determine whether …

Nitric oxide (NO) has been implicated in the local regulation of bone metabolism. However,
the contribution made by specific NO synthase (NOS) enzymes is unclear. Here we show …

Dental pulp tissue exposed to mechanical trauma or cariogenic process results in root canal
and/or periapical infections, and conventionally treated with root canal procedures. The …

In the closing decades of the 20th century, silicon nitride (Si3N4) was extensively developed
for high-temperature gas turbine applications. Technologists attempted to take advantage of …
