Progress in Retinal and Eye Research, 2001
The basis of the duplex theory of vision is examined in view of the dazzling array of data on visual pigment sequences and the pigments they form, on the microspectrophotometry measurements of single photoreceptor cells, on the kinds of photoreceptor cascade enzymes, and on the electrophysiological properties of photoreceptors.

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 and

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.

Summaryfive cases of hydatid disease involving vertebrae have been presented and a brief review of the incidence, pathology, and current treatment of this condition included. it appears that until more effective antiparasitic agents are developed, early, radical and if necessary repeated surgery provides the best prognosis in the management of ...

Current Opinion in Genetics & Development, 1992
Our understanding of the mechanisms that control gastrulation is still in its infancy. One problem is that gastrulation is a complex set of coordinated behaviours involving directional cell movements, several types of cell interactions, changes in cell fate and gene expression.

Annual Review of Cell and Developmental Biology, 2001
▪ Abstract In vertebrates, the paraxial mesoderm corresponds to the bilateral strips of mesodermal tissue flanking the notochord and neural tube and which are delimited laterally by the intermediate mesoderm and the lateral plate. The paraxial mesoderm comprises the head or cephalic mesoderm anteriorly and the somitic region throughout the trunk and ...

Vertebral augmentation, including vertebroplasty and kyphoplasty, is a minimally invasive, image-guided procedure in which cement (typically polymethylmethacrylate (PMMA)) is injected into a vertebral body to treat painful fractures. The majority of vertebroplasty and kyphoplasty procedures are performed to treat symptomatic osteoporotic compression ...

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 ...

Neurosurgery Clinics of North America, 2006
Vertebral osteomyelitis (VO) is an infectious disease of the vertebral body that requires early diagnosis with identification of the infecting organism to direct antibiotic therapy. Most VO can be treated nonsurgically, but 10% to 20% of cases require open surgical treatment.

Visual semiquantitative (SQ) assessment of the radiographs by a trained and experienced observer is the "gold standard" method to detect vertebral fractures. Vertebral morphometry is a quantitative method to identify osteoporotic vertebral fractures based on the measurement of vertebral heights.
