This discrepancy might be explained by the bone type, the small sample geometry, the limited range of strain rates tested here, the type of loading and the method of microdamage detection.
In addition to its primary bone tissues, a bone type is characterized by the presence, density, and arrangement of blood vessels preserved as vascular canals in fossilized bone.
It has been hypothesized that bone lead is continuously released into blood, with the rate of mobilization differing by age and bone type, and that the mobilized lead contributes to adverse health effects (Hu et al. 1998).
Bone tissues can be categorized into two main bone types: the lamellar-zonal bone type (LZB type) and the fibrolamellar bone type (FLB type) [33].
ICTP is released from bone type I collagen by activity of matrix metalloproteinases (MMPs), while CTX-I is generated by cathepsin K activity, but not MMPs [11].
The type I collagen telopeptide fragments, C-telopeptide crosslaps of type I collagen (CTX-1) and C-terminal telopeptide of type I collagen (1CTP), are currently considered as the most sensitive markers of bone resorption and are released from bone type I collagen by different enzymatic pathways.
No statistically significant difference was found in the size of lesions by bone type.
Addis Ababa's "Red Terror" museum, located off historic Meskel Square and reportedly home to a portrait of Karl Marx in the Derg days, holds stacks of skeletons — some paired with names, photos, and belongings, others methodically separated into glass boxes by bone type.
The relationship with blood and patella lead is consistent with the theory that bone lead is chronically released into blood, that mobilization rate in aging differs by bone type, and that this mobilized lead contributes to an acceleration in cognitive decline (Wright et al. 2003).
Implant distribution by bone type and gender is reported in Table 2. Regardless of patient gender and age, higher MBL was observed around implants inserted in the maxilla as compared to the mandible, and this difference was statistically significant for the 4.5 mm platform (P < 0.0001).
