Thyroid hormone status within the physiological range affects bone mass and density in healthy men at the age of peak bone mass [PDF]

open access: yes, 2011
Context: The hormonal factors involved in the regulation of peak bone mass (PBM) in men have not been fully investigated. Apart from gonadal steroids and somatotropic hormones, thyroid hormones are known to affect bone maturation and homeostasis and are ...

Adjusting bone mass for differences in projected bone area and other confounding variables: an allometric perspective. [PDF]

open access: yes, 2002
The traditional method of assessing bone mineral density (BMD; given by bone mineral content [BMC] divided by projected bone area [Ap], BMD = BMC/Ap) has come under strong criticism by various authors. Their criticism being that the projected bone "area"

Lower Newborn Bone Mineral Content Associated With Maternal Use of Tenofovir Disoproxil Fumarate During Pregnancy.

open access: yesClinical Infectious Diseases, 2015
BACKGROUND Fetal bone effects of maternal tenofovir use have not been well studied. We sought to compare whole-body bone mineral content (BMC) of newborns exposed vs not exposed to tenofovir in utero. METHODS We enrolled participants from April 2011 to

Bone Autofluorescence and Mineral Content [PDF]

open access: yesNature, 1965
WHEN ground bone sections are examined microscopically using an ultra-violet light source, some of the osteons autofluoresce with less intensity than others. By reference to tetracycline-marked osteons, it can be shown that the less-fluorescent osteons are those most recently formed.

Regional variation in the microhardness and mineral content of porcine long bones [PDF]

open access: yes, 2007
Pig carcasses are frequently used as models for the human cadaver in the study of trauma and wound patterns. Limited availability and ethical concerns over the use of human tissue has meant that porcine bone is often used as a substitute for human bone ...

Bisphosphonate Treatment Modifies Canine Bone Mineral and Matrix Properties and their Heterogeneity [PDF]

open access: yes, 2010
Bone loss and alterations in bone quality are major causes leading to bone fragility in postmenopausal women. Although bisphosphonates are well known to reduce bone turnover and prevent bone loss in postmenopausal osteoporosis, their effects on other ...

Effect of Gradual Demineralization on the Mineral Fraction and Mechanical Properties of Cortical Bone

open access: yesJournal of Biomechanical Science and Engineering, 2009
Bone is often regarded as a composite material consisting of hydroxyapatite (HAp-like) mineral particles, organic matrix (mostly Type I collagen) and water phases in microscopic scale.
