Morphometric studies on the appendicular bony skeleton of the ostriches (Struthio Camelus)
BMC Veterinary Research, 2023 Background Morphometric study of the bony elements of the appendicular skeleton in the ostrich was fully described and identified. The appendicular skeleton included the bones of the pectoral girdle, the wing, the pelvic girdle and the pelvic limb ...

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 ...

Veterinary Record Case Reports, EarlyView.Abstract Accessory carpal bone fractures are common in horses and may have different aetiologies. Owing to their peculiar shape, internal fixation of these fractures can be challenging for the surgeon, and data on outcomes after surgery are controversial, even if surgical treatment is considered the best approach.

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.

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 ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Hereditary multiple osteochondromas (HMO) is an autosomal dominant disorder caused by heterozygous deleterious variants in the EXT1 or EXT2 genes. While the clinical core phenotype is well established and mainly consists of bone deformities, limb length discrepancies, multiple benign bone neoplasms, and increased risk of chondrosarcoma, the ...

Modelling the anabolic response of bone using a cell population model [PDF]
J Theor Biol 307 (2012) 42-52, 2011 To maintain bone mass during bone remodelling, coupling is required between bone resorption and bone formation. This coordination is achieved by a network of autocrine and paracrine signalling molecules between cells of the osteoclast lineage and cells of the osteoblastic lineage.

Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui
The Anatomical Record, EarlyView.Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.
