International longitudinal pediatric reference standards for bone mineral content

Reference Sheet for International Measurement Standards

Bone Mineral Content and Density.

The availability of high-throughput biochemical and imaging techniques that can be used on live mice has increased the possibility of undertaking longitudinal studies to characterize skeletal changes such as bone mineral content and density. Further characterization of bone morphology, bone quality, and bone strength can also be achieved by analyzing dissected bones using techniques that provid...

Quantitative NMR for Content Assignment of Phytochemical Reference Standards

Reference Standards For reference standards used as primary standards for pharmaceutical quality control, stability testing and inprocess control of herbal medicinal products and respective starting materials a dossier together with a certificate of analysis must be available. In this dossier information on identity testing (e.g. by NMR, MS, IR, UV), purity testing (e.g. water content, residual...

Bone mineral content in bronchopulmonary dysplasia.

Fourteen preterm infants who developed bronchopulmonary dysplasia diagnosed radiologically were compared with a group of similar infants who did not. The two groups were of comparable maturity and birth weight. The clinical histories indicated that those infants with bronchopulmonary dysplasia had had longer periods of supplemental oxygen, more frequent treatment with dexamethasone, and a highe...

Preterm birth and adolescent bone mineral content.

The purpose of this study was to determine the influence of preterm low birth weight on bone mineral content in adolescence. In 2007 to 2008, data on adolescents were obtained for study, including 16 females and 25 males who were born preterm (≤37 weeks' gestation) between October 1, 1989, and December 31, 1995, with a birth weight of less than 1850 g. Preterm low-birth-weight individuals were ...
