Objective: To review the prevalence and location of vertebral pneumatocysts and evaluate the CT findings of these benign lesions.Material and Methods: Retrospectively we reviewed CT images of 89 patients with suspected disc disease during a 6-month period.Results: Distinctive CT pattern of intraosseous pneumatocysts involving the cervical, thoracic ...

The control of vertebrate pests by vertebrate predators
Trends in Ecology & Evolution, 1990Carnivores can control mammalian pests for long periods, but only after pest numbers have been reduced by other means. In Australia, the cause is prolonged dry weather. The consequent low populations of rabbits can then be regulated by European foxes, feral cats and dingoes.

Prion diseases are biologically unique in that the transmissible agent appears to be devoid of nucleic acid and consists of a post-translationally modified host protein. The recognition that variant Creutzfeldt–Jakob disease is caused by the same prion strain as bovine spongiform encephalopathy in cattle has dramatically highlighted the need for a ...

This chapter introduces the beginning of Pleistocene vertebrate records, starting from an overview of the Plio-Pleistocene transition. Understanding the Early Pleistocene vertebrate record is impossible without the knowledge of the events characterizing the setting of Early Pleistocene land vertebrate communities.

Current Opinion in Genetics & Development, 1997
Homologs of the Notch receptor and its ligands participate in cell fate decisions during vertebrate development. The past year has seen significant advances in knowledge of the role of Notch in Xenopus neuronal development and T-cell development and in our understanding of the Notch signalling pathway in vertebrates.

Patterns of Vertebrate Neurogenesis and the Paths of Vertebrate Evolution
Brain, Behavior and Evolution, 1998Any substantial change in brain size requires a change in the number of neurons and their supporting elements in the brain, which in turn requires an alteration in either the rate, or the duration of neurogenesis. The schedule of neurogenesis is surprisingly stable in mammalian brains, and increases in the duration of neurogenesis have predictable ...

Epidemiology of Vertebral Fractures: Implications for Vertebral Augmentation
Academic Radiology, 2006To put vertebral augmentation (eg, vertebroplasty) into perspective, the etiology and outcomes of vertebral fractures are reviewed. There is considerable debate about which criteria should be used to define a vertebral fracture because there is no consistent relation between symptoms and the degree of vertebral deformity.

La Radiologia medica, 1997
Osteoporotic vertebral fracture often results in asymptomatic and atraumatic deformity of vertebral body, therefore the qualitative radiological evaluation alone may lead to disagreement about whether a vertebra is fractured. Morphometry based on measurements of vertebral body heights is a reliable and reproducible technique for vertebral fracture ...
