Background: Somatic and bone development have each been studied in detail, but rarely in conjunction.
Aim: The aim of this study was to determine what somatic and bone development have in common and how they differ. A second aim was to check for a pubertal spurt in bone age (BA) and to quantify it in a similar way as has been done for height. The Preece-Baines model is used to fit longitudinal data for BA.
Subjects And Methods: The data analysed are from the 1st Zurich Longitudinal Growth Study comprising 120 boys and 112 girls with almost complete data from birth to adulthood.
Results: Variability of somatic milestones was reduced in terms of BA and there was an aftergrowth after reaching adult RUS score 1000. A strong increase in the RUS score was seen at a late stage of the pubertal spurt (PS). Somatic milestones correlated with the RUS score attained at these ages and more so at an early stage of the PS. A PS for BA was clearly identified with a location at 14.2 years for boys and 12.2 years for girls. Age of peak bone development correlated highly with age of peak velocity of somatic variables.
Conclusions: BA can be successfully modelled as a semi-quantitative entity. Bone development shows marked associations with somatic development, despite the fact that the latter reflects changes in size, while the former is essentially a maturity index and reflects changes in biochemical composition of tissues.

FRAX, a risk calculator that provides individualized 10-year probabilities of hip and major osteoporotic fracture, has been widely used for fracture risk assessment since its launch in 2008. It is now incorporated into very many guidelines worldwide to inform osteoporosis management. In this review, we explore the development of FRAX and how it enhances fracture risk prediction as compared to use of bone mineral density alone, as well as approaches to utilizing FRAX in determining intervention and assessment thresholds.

Alzheimer's disease (AD) and osteoporosis (OP) pose distinct but interconnected health challenges, both significantly impacting the aging population. AD, a neurodegenerative disorder characterized by memory impairment and cognitive decline, is primarily associated with the accumulation of abnormally folded amyloid beta (Aβ) peptides and neurofibrillary tangles in the brain. OP, a skeletal disorder marked by low bone mineral density, involves dysregulation of bone remodeling and is associated with an increased risk of fractures.

Anterior-posterior (A-P) elongation of the palate is a critical aspect of integrated midfacial morphogenesis. Reciprocal epithelial-mesenchymal interactions drive secondary palate elongation that is coupled to the periodic formation of signaling centers within the rugae growth zone (RGZ). However, the relationship between RGZ-driven morphogenetic processes, the differentiative dynamics of underlying palatal bone mesenchymal precursors, and the segmental organization of the upper jaw has remained enigmatic.

Background: Skeletal dysplasia (SD) represents a series of highly heterogeneous congenital genetic diseases affecting the human skeletal system. Refined genetic diagnosis is helpful for the accurate diagnosis and prognosis evaluation of SDs.
Materials And Methods: In this study, we recruited 26 cases of SD and analyzed them with a designed sequential genetic detection.
