background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

BACKGROUND & OBJECTIVES CAGE-AID questionnaire is a short, useful screening tool for substance dependence. Assessment of one family member for the screening of substance dependence in the family could be useful in clinical practice and research. In this study, we aimed to assess the validity of the Family CAGE-AID questionnaire for the diagnosis of substance dependence. METHODS Cross-sectiona...

BACKGROUND To investigate how unilateral cage-instrumented posterior lumbar interbody fusion (PLIF) affects the three-dimensional flexibility in degenerative disc disease by comparing the biomechanical characteristics of unilateral and bilateral cage-instrumented PLIF. METHODS Twelve motion segments in sheep lumbar spine specimens were tested for flexion, extension, axial rotation, and latera...

cage birds like canaries can potentially harbor human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. considering many people's interests to keep canaries, present study was conducted in canaries from yazd to investigate the beta-lactam antibiotics resistant escherichia coli. 109 e. coli isolates from canary faeces in yazd were evaluated to...

Cap analysis gene expression (CAGE) is a high-throughput, tag-based method designed to survey the 5' end of capped full-length cDNAs. CAGE has previously been used to define global transcription start site usage and monitor gene activity in mammals. A drawback of the CAGE approach thus far has been the removal of as many as 40% of CAGE sequence tags due to their mapping to multiple genomic loca...

Impact of Atlantic salmon (Salmo salar) cage culture in Mjoifjordur, Eastern Iceland on the chemistry of the sediment was investigated. Sediment samples were collected using a Shipek grab on 29.12.2003. A core sub-sample has taken from each grab for analyzing total organic matter, total organic carbon, total nitrogen and phosphorus in different depths of samples from three stations at various d...
