In vivo imaging of cortical porosity by synchrotron phase contrast micro computed tomography
Cortical bone is a dynamic tissue which undergoes adaptive and pathological changes throughout life. An improved understanding of the spatio-temporal process of remodeling holds great promise for improving our understanding of bone development, maintenance and senescence. The use of micro-computed …

Interactions Between Aging and Chronic Kidney Disease on the Skeleton
… population presents an additive fracture risk. Cortical porosity is a central tenet underlying skeletal fragility and occurs in CKD and aging. Previous research on cortical porosity has focused on preventing pore formation, while research on pore reversal (infilling) is lacking. Pore infilling …

The muscle-bone in children and adolescents with and without cystic fibrosis
… and proximal total area(Tt.ArandCSA), distal cortical porosity(Ct.Po) and proximal bone strength(SSI) but higher apparent gains in distal and proximal cortical bone density(Ct.BMD,Ct.TMD,vBMD). Females had consistently lower distal total area(total CSA) and density(totalvBMD), distal …

Approaches to Improve the Structure and Function of the Skeleton in Chronic Kidney Disease
… CKD is predominately driven by deteriorations in cortical bone, highlighted by significant cortical porosity development. It is hypothesized that cortical porosity is largely driven by chronically high levels of parathyroid hormone (PTH), which alters the balance of bone remodeling in favor of …

Impact of Hyperglycemia on Rat Cortical Bone Microstructure and Osteoprogenitor Cell Exhaustion
… rats, which might increase cellular level cortical porosity. In this context, since there are examples of increased proliferation of cells in hyperglycemia from other tissues, we hypothesized that increased osteocyte cell number due to the excessive proliferation of osteoprogenitors …

Relating cortical bone mechanics to intracortical pore morphology, distribution and remodeling history within the fibula diaphysis
Introduction: During aging and osteoporosis, the cortical bone becomes more porous, making it more fragile and susceptible to fractures. The aim of this study was to investigate the intracortical compression-induced strain energy distribution, and determine whether the intracortical pores …

The quantification of pregnancy-induced bone mineral mobilisation in the maternal appendicular skeleton with novel peripheral quantitative computed tomography (pQCT) techniques.
… bone is more metabolically active than cortical bone in part due to its structure, orientation and much greater surface area. During lactation, studies have consistently reported significant transient bone mineral mobilisation from trabecular-rich axial sites such as the hip and spine, …
