The results from an experimental and numerical study of a known mouse cage (static microisolator type) placed in a wind tunnel are presented. The study involved the collection of experimental airflow data and the use of these data in the validation of the computational fluid dynamics (CFD) cage model. This validation was important as it then allowed the CFD cage model to be used to represent ca...

Behaviour and use of the cage area were studied in 96 rabbits (Oryctolagus cuniculus) kept in an enriched cage system - with access to shelter and raised height at the back of the cage - and in a conventional cage system to estimate the effects of the environmental enrichment on the rabbits' welfare. The rabbits' behaviour and placement in the cage were observed, using continuous video recordin...

An operational definition of collective cage variables previously introduced for liquid argon is extended, via a molecular dynamics study, to the rotational properties of axially symmetric molecules. Quantitative measures of the static and dynamic cage properties are extracted for liquid Cl2 near the triple point. The collective cage variables are well described by the potential acting on an ar...

Recommendations for the amount of cage space required for female mice with litters were first made in the 2011 Guide for the Care and Use of Laboratory Animals. We hypothesized that if a difference in mouse behavior and reproduction exists within the limits of commercially available caging, this difference would be detected between the smallest and largest cages. C57BL/6NCrl and Crl:CD1(Icr) br...

Using first principles theory based on density functional formulation we have studied the energetics and thermal stability of storing hydrogen in B-N-based nanostructures. We show that hydrogen molecule enters through the hexagonal face of the B36N36 cage and prefers to remain inside the cage in molecular form. The energy barriers for the hydrogen molecule to enter into or escape from the cage ...

The purpose of this study was to compare environmental conditions and mice in cages with four different mechanical ventilation designs and a static isolator cage. Environmental conditions (air velocity, temperature, relative humidity, bedding weight change, airborne dust, NH3, and CO2) were compared for each cage type (n = 5 per cage). Bedding type was chipped hardwood. Mouse response in each c...

BACKGROUND Initial promise of a stand-alone interbody fusion cage to treat chronic back pain and restore disc height has not been realized. In some instances, a posterior spinal fixation has been used to enhance stability and increase fusion rate. In this manuscript, a new stand-alone cage is compared with conventional fixation methods based on the finite element analysis, with a focus on inves...

Study Design A retrospective clinical case series. Purpose To determine the strength of association between cage retropulsion and its related factors. Overview of Literature Lumbar interbody fusion with cage can obtain a firm union and can restore the disc height with normal sagittal and coronal alignment. Although lumbar interbody fusion procedures have satisfactory clinical outcomes, peri...
