Fibrous Dysplasia versus Juvenile Ossifying Fibroma: A Dilemma

Case Reports in Dentistry, 2016
Fibrous dysplasia (FD) is a condition characterized by excessive proliferation of bone forming mesenchymal cells which can affect one bone (monostotic type) or multiple bones (polyostotic type). It is predominantly noticed in adolescents and young adults.

Secondary aneurysmal bone cyst of the frontal bone with fibrous dysplasia showing rapid expansion: a case report [PDF]

, 2023
A 19-year-old woman presented with swelling of the left forehead without pain. She did not have any relevant past or family history. Computed tomography showed destruction of the outer cortex of the frontal bone.

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 ...

Transverse navicular bone fracture in a hindlimb of a young Warmblood mare

Equine Veterinary Education, EarlyView.
Summary A 2.5‐year‐old Warmblood filly presented with an acute onset of severe right hindlimb lameness and pastern region swelling of 2 weeks' duration. Radiographic examination revealed a transverse (horizontal) displaced fracture of the navicular bone and subluxation of the distal interphalangeal (DIP) joint.

A Rare Case of Radiculopathy: Monostotic Fibrous Dysplasia of the Sacrum

Acta Médica Portuguesa, 2019
Fibrous dysplasia is a bone disease characterized by an osteoblastic dysfunction resulting in a fibrous replacement of the normal medullary bone. We describe the case of a 33-year-old who presented with low back pain irradiating to her right leg.

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Constitutive Laws and Failure Models for Compact Bones Subjected to Dynamic Loading [PDF]

Computer Methods in Biomechanics and Biomedical Engineering 5 (2002) 351-359, 2005
Many biological tissues, such as bones and ligaments, are fibrous. The geometrical structure of these tissues shows that they exhibit a similar hierarchy in their ultra-structure and macro-structure. The aim of this work is to develop a model to study the failure of fibrous structures subjected to dynamic loading. The important feature of this model is

On the structure of topological spaces [PDF]

arXiv, 2021
The structure of topological spaces is analysed here through the lenses of fibrous preorders. Each topological space has an associated fibrous preorder and those fibrous preorders which return a topological space are called spacial. A special class of spacial fibrous preorders consisting of an interconnected family of preorders indexed by a unitary ...

The surgical management of fibrous dysplasia of bone [PDF]

, 2012
The surgical management of Polyostotic Fibrous Dysplasia (FD) of bone is technically demanding. The most effective methods to manage the associated bone deformity remain unclear. The marked variation in the degree and pattern of bone involvement has made

ScaffoldNet: Detecting and Classifying Biomedical Polymer-Based Scaffolds via a Convolutional Neural Network [PDF]

arXiv, 2018
We developed a Convolutional Neural Network model to identify and classify Airbrushed (alternatively known as Blow-spun), Electrospun and Steel Wire scaffolds. Our model ScaffoldNet is a 6-layer Convolutional Neural Network trained and tested on 3,043 images of Airbrushed, Electrospun and Steel Wire scaffolds.
