Biomechanics of Vertebral Fractures and the Vertebral Fracture Cascade
Current Osteoporosis Reports, 2010Vertebral fractures (VFxs) are the most common osteoporotic fracture, and are a strong risk factor for future fracture. The presence of a VFx greatly increases the risk of sustaining subsequent VFxs-a phenomenon often referred to as the "vertebral fracture cascade." VFxs do not occur uniformly along the spine, but occur more often at the mid-thoracic ...

Diagnosis of Vertebral Fractures by Vertebral Fracture Assessment
Journal of Clinical Densitometry, 2006Vertebral fractures are independent risk factors for both vertebral and peripheral fractures and only one-third of these fractures come to clinical attention. Vertebral fracture assessment (VFA) is a radiographic method using dual X-ray absorptiometry (DXA) to assess vertebral deformities during bone density measurement.

Vertebral Body Osteonecrosis Without Vertebral Collapse
Spine, 2003A case of idiopathic focal vertebral body osteonecrosis without vertebral collapse is reported.To report a rare case of focal vertebral osteonecrosis and to clarify the features of imaging studies.There are no previous reports describing focal vertebral body necrosis without collapse in the literature.A case report and literature review are presented ...

Vertebral infection represents 2-4% of all cases of osteomyelitis. An increase in the incidence of pyogenic as well as granulomatous spondylitis has been noticed. Early radiological diagnosis is of great importance for prompt treatment and prevention of clinically significant consequences which include neural compromise and late spinal deformities. The

Mild morphometric vertebral fractures predict vertebral fractures but not non-vertebral fractures
Osteoporosis International, 2013In this meta-analysis of the control arms of four phase 3 trials, mild vertebral fractures were a significant risk factor for future vertebral fractures but not for non-vertebral fracture.A prior vertebral fracture is a risk factor for future fracture that is commonly used as an eligibility criterion for treatment and in the assessment of fracture ...

The retina is an outpost of the central nervous system (CNS) with neuronal structures and proteins specialized for the transduction of light signals into a neural code that the brain can interpret. Mutations of proteins involved in phototransduction or synaptic transmission through the retina produce visual deficits ranging from subtle color vision ...

Seminars in Cell & Developmental Biology, 1994
The recent identification of Wnt-7a as a signalling molecule in dorsal/ventral patterning means that we now have a known signal for control of each of the three limb axes. Fibroblast growth factors can allow proximal/distal patterning and Sonic hedgehog gene expression signals anterior/posterior patterning. Networks of these signals not only coordinate

The Chromosomes of the Vertebrates
1951Publisher Summary Chromosomal characteristics can render precious services in investigations of phylogenetic order. The chromosomes constitute the most important, if not the only, substrate of the genes. The evolution of chromosomal systems must necessarily be connected with the evolution of organic systems— that is, of living beings. In other words,
