Age-Related Changes in Bone Remodelling and Structure in Men: Histomorphometric Studies

Age-Related Changes in Bone Remodelling and Structure in Men: Histomorphometric Studies

Histomorphometric studies of the age-related changes in bone remodelling and structure in men are relatively sparse and mainly limited to the iliac crest. The available data indicate that loss of trabecular bone is predominantly due to decreased formation at the level of individual bone remodelling units and that an increase in remodelling rate does not play a major role. The main structural co...

A histomorphometric study on age-related changes in selected lymphoid structures of Chukar partridge (Alectoris chukar)

Background: Chukar partridge (Alectoris chukar) is raised for its highly nutritional and relatively expensive meat. Aims: This study evaluates selected lymphoid organs of juvenile and peripubertal Chukar partridges using a histomorphometric approach. Methods: Thirty one-day-old male and female Chukar partridges were included in the stu...

Age related changes in indices of bone metabolism and oxidative stress in Postmenopausal women in Southern Nigeria

Background and Objectives: Oxidative stress (OS) associated with estrogen deficiency in menopause has been implicated in various complications of menopause. Some indices of OS, bone metabolism, and uric acid (UA) in postmenopausal women were assessed as possible predictors of gouty osteoarthritis. Materials and Methods: This case-control study enrolled 40 postmenopausal women and 60 premenopau...

Bone Structure and Bone Remodelling

Age-related changes in mouse bone permeability.

The determination of lacunar-canalicular permeability is essential for understanding local fluid flow in bone, which may indicate how bone senses changes in the mechanical environment to regulate mechano-adaptation. The estimates of lacunar-canalicular permeability found in the literature vary by up to eight orders of magnitude, and age-related permeability changes have not been measured in non...
