Mineralization generates megapascal contractile stresses in collagen fibrils
H Ping, W Wagermaier, N Horbelt, E Scoppola, C Li… - Science, 2022 - science.org
During bone formation, collagen fibrils mineralize with carbonated hydroxyapatite, leading to
a hybrid material with excellent properties. Other minerals are also known to nucleate within …

Crossfibrillar mineral tessellation in normal and Hyp mouse bone as revealed by 3D FIB-SEM microscopy
In bone, structural components such as mineral extend across length scales to provide
essential biomechanical functions. Using X-ray micro-computed tomography (µCT), and …

[HTML][HTML] Bone structure and composition in a hyperglycemic, obese, and leptin receptor-deficient rat: Microscale characterization of femur and calvarium
Metabolic abnormalities, such as diabetes mellitus and obesity, can impact bone quantity
and/or bone quality. In this work, we characterize bone material properties, in terms of …

Rapid collagen-directed mineralization of calcium fluoride nanocrystals with periodically patterned nanostructures
Collagen fibrils present periodic structures, which provide space for intrafibrillar growth of
oriented hydroxyapatite nanocrystals in bone and contribute to the good mechanical …

Impaired bone quality in the superolateral femoral neck occurs independent of hip geometry and bone mineral density
S von Kroge, J Stürznickel, U Bechler, KE Stockhausen… - Acta Biomaterialia, 2022 - Elsevier
Skeletal adaptation is substantially influenced by mechanical loads. Osteocytes and their
lacuno-canalicular network have been identified as a key player in load sensation and bone …

After an initial balance favoring collagen formation and mineralization, bone turnover markers return to pre-treatment levels during long-term TNF-α inhibition in …
M Siderius, A Spoorenberg, FGM Kroese… - Plos one, 2023 - journals.plos.org
Background Bone turnover balance favors bone formation, especially mineralization, during
the first 3 years of treatment with TNF-α inhibitors (TNFi). Our aim was to evaluate the course …

A multiscale study of structural and compositional changes in a natural nanocomposite: Osteoporotic bone with chronic endogenous steroid excess
Glucocorticoid (or steroid) induced osteoporosis (GIOP) is the leading form of secondary
osteoporosis, affecting up to 50% of patients receiving chronic glucocorticoid therapy. Bone …

[HTML][HTML] Pronounced cortical porosity and sex-specific patterns of increased bone and osteocyte lacunar mineralization characterize the human distal fibula with aging
RN Hering, S von Kroge, J Delsmann, A Simon… - Bone, 2024 - Elsevier
The high occurrence of distal fibula fractures among older women suggests a potential link
to impaired bone health. Here we used a multiscale imaging approach to investigate the …

Globular structure of the hypermineralized tissue in human femoral neck
Bone becomes more fragile with ageing. Among many structural changes, a thin layer of
highly mineralized and brittle tissue covers part of the external surface of the thin femoral …
