Assessing bone maturity: Compositional and mechanical properties of rib cortical bone at different ages

Association between nanoscale strains and tissue level nanoindentation properties in age-related hip-fractures

“…Thermogravimetric analysis and Differential Scanning Calorimetry was carried out by using a TGA/DSC 3+ (Mettler Toledo®, Indium calibrated) with a two-phase experiment (Bonicelli et al, 2022): (i) dynamic temperature increase from 25 to 550 • C at a rate of 10 • C/min and (ii) a static phase in which 550 • C are kept for 10 min in order to completely eliminate the organic matrix and reduce the bone to ashes (Fig. 3).…”

Abstracts from the 14th International Conference on Osteogenesis Imperfecta, Sheffield, UK, 30 August – 2 September 2022

“…2 UFRB, Santo Antonio de Jesus, Brazil ABSTRACT OBJECTIVES: Osteogenesis Imperfecta (OI) is a chronic disease with no known cure that can affect the quality of life (QoL) 1,2 . Most studies that evaluate children's QoL have parents or caregivers as informants [3][4][5][6][7][8][9] . However, proxy reports are not always convergent with self-reports, and children can reliably express opinions and feelings about their own QoL if age-appropriate instruments are used [3][4][5][6][7][8][9] .…”

“…Most studies that evaluate children's QoL have parents or caregivers as informants [3][4][5][6][7][8][9] . However, proxy reports are not always convergent with self-reports, and children can reliably express opinions and feelings about their own QoL if age-appropriate instruments are used [3][4][5][6][7][8][9] . In this study, we aim to evaluate the QoL of pediatric patients with OI, based on their own health perception.…”

“…Compositional and material changes are observed in bone tissue as it ages, where properties such as hardness increase until around 35 years of age but then gradually decline in association with physicochemical changes, resulting in increased bone fragility. 9 Extrinsic factors can also influence fragility; at a significantly high strain rate (high rate of deformation with respect to time), every bone is brittle. 10 Moreover, aging shifts this ductile-to-brittle transition to lower strain rates such that older bones are more brittle and thus susceptible to fracture.…”

Effect of Collagen Molecules and Hydroxyapatite Salt on Thermal Properties of Rib, Scapula, and Femur of Some Bovines under Normal and Decalcified Conditions

“…The mineral content of the bone is very much dependent on the age, water, and organic content of the bone which also affects its physiological and biophysical properties. [12][13][14][15] Oikarinen 16 prepared decalcified bone matrix from the cortical bones of rats. Rauf and SI Ahmad 3 used a uniform bending technique to study the y properties of normal and decalcified rib, femur, and scapula bones of camel and ox.…”
