Aging bone

Russian Journal of Geriatric Medicine, 2020
This review article deals with the topic of changes in bone tissue in the process of aging of the body. Adipogenesis and osteogenesis are affected at the molecular level, proteins and genes are described, in which somatic mutation can occur during the aging process, resulting in both minor changes and an active loss of bone mineral density. The factors

A Novel Shorthand Approach to Knee Bone Age Using MRI: A Validation and Reliability Study

Orthopaedic Journal of Sports Medicine, 2021
Background: Bone-age determination remains a difficult process. An atlas for bone age has been created from knee-ossification patterns on magnetic resonance imaging (MRI), thereby avoiding the need for radiographs and associated costs, radiation exposure,

Intelligent Bone Age Assessment: An Automated System to Detect a Bone Growth Problem Using Convolutional Neural Networks with Attention Mechanism

Diagnostics, 2021
Skeletal bone age assessment using X-ray images is a standard clinical procedure to detect any anomaly in bone growth among kids and babies. The assessed bone age indicates the actual level of growth, whereby a large discrepancy between the assessed and ...

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age [PDF]

, 2018
Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply.
