Estimating and abstracting the 3D structure of bones using neural networks on X-ray (2D) images [PDF]

Communications biology, 2020, 3(1), pp.1-13, 2020
In this paper, we present a deep-learning based method for estimating the 3D structure of a bone from a pair of 2D X-ray images. Our triplet loss-trained neural network selects the most closely matching 3D bone shape from a predefined set of shapes. Our predictions have an average root mean square (RMS) distance of 1.08 mm between the predicted and ...

Evaluation of Low Bone Mineral Mass Using a Combination of Peripheral Bone Mineral Density and Total Body Composition Variables by Neural Network [PDF]

, 2015
The aim of this work was to evaluate low bone mass using the feed-forward neural network (NN) with good accuracy taking into account the forearm and heel bone mineral density (BMD) as well as total body composition variables.

Expression of microRNAs that regulate bone turnover in the serum of postmenopausal women with low bone mass and vertebral fractures.

European Journal of Endocrinology, 2017
BACKGROUND Circulating microRNAs (miRs) are currently being investigated as novel biomarkers for osteoporosis and osteoporotic fractures. AIM The aim of this study was to investigate serum levels of specific microRNAs, known regulators of bone ...

Impact of Genetics on Low Bone Mass in Adults

Journal of Bone and Mineral Research, 2008
Abstract Low bone mass in adults is a major risk factor for low-impact fractures and is considered of complex origin because of interaction of environmental and genetic factors, each with modest effect. The objective was to assess the relative impact of genetics and environment and quantify the risk in relatives of osteopenic individuals.

Positive impact of low-dose, high-energy radiation on bone in partial- and/or full-weightbearing mice [PDF]

, 2019
Astronauts traveling beyond low Earth orbit will be exposed to galactic cosmic radiation (GCR); understanding how high energy ionizing radiation modifies the bone response to mechanical unloading is important to assuring crew health. To investigate this,

Low bone mass and changes in the osteocyte network in mice lacking autophagy in the osteoblast lineage

Scientific Reports, 2016
Autophagy maintains cell function and homeostasis by recycling intracellular components. This process is also required for morphological changes associated with maturation of some cell types.

Bone loss: Quantitative imaging techniques for assessing bone mass in rheumatoid arthritis [PDF]

, 2000
Osteoporosis is associated with low bone mass and microarchitectural deterioration of bone tissue with clinical manifestation of low trauma fractures. Rheumatoid arthritis (RA) is a risk factor due to generalized and articular bone loss.
