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...

a 45- year old man with a history of aortic valve replacement presented with acute chest pain which was diagnosed to be anterior wall myocardial infarction. he received thrombolytic therapy with streptokinase. echocardiography and fluoroscopy showed normally functioning ball and cage aortic prosthesis. coronary arteriography showed globular filling defect in midportion of left anterior descendi...

This study was conducted in cage aquaculture villages in Hongngu District, Dong Thap Province of Vietnam during November 2001 to November 2002. Cage culture areas are located in the confluence of So Thuong Canal and one branch of the Mekong River. The purposes of this study were to investigate the cage culture system and its related environmental conditions, to determine the quality and quantit...

The GroEL/GroES chaperonin system acts as a passive anti-aggregation cage for refolding rubisco and rhodanese, and not as an active unfolding device. Refolding aconitase is too large to enter the cage but reversible binding to GroEL reduces its aggregration. Unexpectedly, confinement in the cage increases the rate of refolding of rubisco, but not rhodanese.

A cubic cage complex assembled from twelve bis-bidentate ligands and eight Co(II) ions provides a cavity that selectively recognises and binds coumarin in MeCN solution. The cage portals are large enough to allow guest exchange, but small enough to provide a kinetic trap; the cage paramagnetism facilitates detailed NMR analysis.

A hollow iridium-cornered prismatic cage was self-assembled without the assistance of any template. The cage was found to be capable of encapsulating heteroguest's triplet in its perfect sized cavity, producing the first demonstration of quintuple structure by an octahedral metal cornered prismatic cage.

Abstract Aquaculture has been the world’s fastest-growing food producing method and grown to become second-largest export industry in Norway during past 40 years. Usually, high-value fish such as Atlantic Salmon (Salmo Salar) is raised a multi-cage farm, where flow interactions between cages exist. In this study, are implemented into numerical program, FhSim, investigate its influences on respo...
