Bone Reports, 2023 An apparent vitamin D paradox, characterized by lower serum 25-hydroxyvitamin D (25(OH)D) levels and higher bone mineral density, is present in black population. In contrast, blacks have higher serum 1,25-dihydroxyvitamin D (1,25(OH)2D) levels.

Immunoporosis: Role of immune system in the pathophysiology of different types of osteoporosis
Frontiers in Endocrinology, 2022 Osteoporosis is a skeletal system disease characterized by low bone mass and altered bone microarchitecture, with an increased risk of fractures. Classical theories hold that osteoporosis is essentially a bone remodeling disorder caused by estrogen ...

Bone Adaptation as a Geometric Flow [PDF]
arXiv, 2021 This paper presents bone adaptation as a geometric flow. The proposed method is based on two assumptions: first, that the bone surface is smooth (not fractal) permitting the definition of a tangent plane and, second, that the interface between marrow and bone tissue phases is orientable.

Physically based 3D finite element model of a single mineralized collagen microfibril [PDF]
Journal of Theoretical Biology 301 (2012) 28-41, 2012 Mineralized collagen microfibrils in human bone provide its mechanical properties (stiffness, elasticity, ductility, energy dissipation and strength). However, detailed 3D finite element models describing the mechanical behaviour of the mineralized collagen microfibrils are still lacking.

Redox Metabolism and Vascular Calcification in Chronic Kidney Disease
Biomolecules, 2023 Vascular calcification (VC) is a common complication in patients with chronic kidney disease which increases their mortality. Although oxidative stress is involved in the onset and progression of this disorder, the specific role of some of the main redox

Synchrotron imaging assessment of bone quality [PDF]
, 2016 Bone is a complex hierarchical structure and its principal function is to resist mechanical forces and fracture. Bone strength depends not only on the quantity of bone tissue but also on the shape and hierarchical structure.
