ABSTRACT The most common cause of spinal cord injury are high impact trauma, which often result in some motor impairment, sensory or autonomic a greater or lesser extent in the distal areas the level of trauma. In terms of survival and complications due to sequelae, veterinary patients have a poor prognosis unfavorable. Therefore justified the study of experimental models of spinal cord injury production that could provide more support to research potential treatments for spinal cord injuries in medicine and veterinary medicine. Preclinical studies of acute spinal cord injury require an experimental animal model easily reproducible. The most common experimental animal model is the rat, and several techniques for producing a spinal cord injury. The objective of this study was to describe and evaluate the effectiveness of acute spinal cord injury production technique through inflation of Fogarty(r) catheter using rabbits as an experimental model because it is a species that has fewer conclusive publications and contemplating. The main requirements of a model as low cost, handling convenience, reproducibility and uniformity. The technique was adequate for performing preclinical studies in neuro-traumatology area, effectively leading to degeneration and necrosis of the nervous tissue fostering the emergence of acute paraplegia.

Redes de junções Josephson são dispositivos supercondutores com importantes aplicações tanto em tecnologia quanto em ciência básica. Neste artigo mostramos como estes dispositivos funcionam, suas propriedades magnéticas e de transporte, e como através das quais é possível estudar propriedades ainda controversas dos sistemas supercondutores granulares tais como o Efeito Meissner Paramagnético (PME), a Avalanche de Vórtices (VA) e outros efeitos relacionados com a granularidade.

Arrays of Josephson junctions are powerful superconducting devices with both technological and basic applications. In this review article, we describe how these devices work as well as their transport and magnetic properties. We also show how they can be used to explain some of the controversial properties of granular superconducting systems, like Paramagnetic Meissner Effect (PME), Vortex Avalanche (VA) and other granularity-related e ects.
