Triquetral Osteoid Osteoma: A Diagnostic Dilemma
Journal of Orthopedic and Spine Trauma, 2020 Background: Osteoid osteoma (OO) is a benign osteoblastic neoplasm, mostly occurring in long bones of lower extremity. Its manifestation in unusual locations can be a diagnostic challenge and distressing for patients.

Physics Driven Domain Specific Transporter Framework with Attention Mechanism for Ultrasound Imaging [PDF]
arXiv, 2021 Most applications of deep learning techniques in medical imaging are supervised and require a large number of labeled data which is expensive and requires many hours of careful annotation by experts. In this paper, we propose an unsupervised, physics driven domain specific transporter framework with an attention mechanism to identify relevant key ...

The Role of Osteocytes in Targeted Bone Remodeling: A Mathematical Model [PDF]
PLoS ONE 2013 May 22; 8(5): e63884, 2012 Until recently many studies of bone remodeling at the cellular level have focused on the behavior of mature osteoblasts and osteoclasts, and their respective precursor cells, with the role of osteocytes and bone lining cells left largely unexplored. This is particularly true with respect to the mathematical modeling of bone remodeling.

Bone Adaptation as a Geometric Flow [PDF]
arXiv, 2021 This paper presents bone adaptation as a geometric flow. The proposed method is based on two assumptions: first, that the bone surface is smooth (not fractal) permitting the definition of a tangent plane and, second, that the interface between marrow and bone tissue phases is orientable.

Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies
Advanced Science, EarlyView.The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

Endocortical bone loss in osteoporosis: The role of bone surface availability [PDF]
Int J Numer Meth Biomed Engng (2013) 29:1307-1322, 2012 Age-related bone loss and postmenopausal osteoporosis are disorders of bone remodelling, in which less bone is reformed than resorbed. Yet, this dysregulation of bone remodelling does not occur equally in all bone regions. Loss of bone is more pronounced near and at the endocortex, leading to cortical wall thinning and medullary cavity expansion, a ...
