BONE MINERALIZATION AND BONE MINERAL CONTENT IN PRIMARY HYPERPARATHYROIDISM
Acta Endocrinologica, 1977ABSTRACT The degree of bone mineralization and the bone mineral content (BMC) was evaluated in 6 patients with primary hyperparathyroidism. The degree of bone mineralization was estimated as the phosphorus/hydroxyproline ratio (P/Hypro) in bone biopsies; BMC was estimated by photon absorptiometry on both forearms.

Bone Quality—Beyond Bone Mineral Density
Seminars in Musculoskeletal Radiology, 2016Both bone mass and quality are responsible for bone strength. Whereas bone mass is measured with bone mineral density, quantification of bone quality is more complex and involves bone architecture, texture, and mechanical parameters. Over the last decade, significant progress has been made in developing technologies to measure bone quality.

A study on the evolution with age of the mineral composition of bones was performed on samples belonging to human and other common mammalian species (cattle, sheep, dog). The study was carried out on the ashes obtained by calcination of the bone samples (1 h at 900 degrees C).

Abstract. The uptake of 85Sr in the spine and both the bone mineral linear density (g/cm) and mineral density (g/cm3) of the trabecular radius, midshaft radius and ulnae have been measured in 21 untreated sarcoid patients, using the 241Am γ‐transmission method.

Noninvasive bone mineral measurements
Seminars in Nuclear Medicine, 1983Single and dual photon absorptiometry are now available to aid the physician in diagnosis and management of generalized bone diseases. Both methods are reviewed in detail. They allow an accurate and reproducible assessment of bone mineral at predominantly cortical (appendicular skeleton) and trabecular (axial skeleton) bone sites.

Bone mineral density and bone mineral content among female elite athletes
Bone, 2019Exercise is a protective factor for the appearance of osteoporosis, but not all physical activities have the same effect on bones. Low-impact sports, like swimming, may a have a negative or no effect. The aim of the present study is to evaluate bone mineral density (BMD, g/cm2) and bone mineral content (BMC, kg) among female high performance athletes ...

Although bones are normally thought of as supporting structures that fracture when one falls, bone is actually a very active metabolic organ. It is vital in the regulation of calcium and phosphate metabolism, magnesium storage, and in buffering metabolic acido-sis. Bone and mineral metabolism and some of their disorders are presented in this article.

Measuring Bone Mineral Content
Orthopaedic Nursing, 1991Orthopaedic nurses encounter many patients with fractures related to osteoporosis. This article discusses the most available methods of measuring bone mineral content (BMC) to diagnose osteoporosis. The methods include single photon absorptiometry, dual photon absorptiometry, and dual photon absorptiometry using x-rays and computerized tomography.

Clinical Orthopaedics and Related Research, 1985
This is a review of the chemistry and structure of synthetic, mineral, and biologic hydroxyapatites. Bone apatite has a large, reactive specific-surface and is characterized by its crystal imperfection and non-stoichiometry. Precipitated and bone hydroxyapatites are in the submicroscopic size range where their solubility decreases rapidly with a small ...

Disorders of bone and bone mineral metabolism
2014Metabolic bone disorders are very common in the general population and untreated, they can cause a variety of neurologic symptoms. These diseases include osteoporosis, vitamin D deficiency, Paget's disease, and alterations in calcium, phosphorus, and magnesium metabolism. Diagnosis is made through analysis of metabolic bone blood chemistries as well as
