BACKGROUND AND PURPOSE Metal artifact reduction sequence (MARS) MRI and ultrasound scanning (USS) can both be used to detect pseudotumors, abductor muscle atrophy, and tendinous pathology in patients with painful metal-on-metal (MOM) hip arthroplasty. We wanted to determine the diagnostic test characteristics of USS using MARS MRI as a reference for detection of pseudotumors and muscle atrophy....
Although a gene's location can greatly influence its expression, genome sequencing has shown that orthologous genes may exist in very different environments in the genomes of closely related species. Four genes in the maize alcohol dehydrogenase (adh1) region represent solitary genes dispersed among large repetitive blocks, whereas the orthologous genes in sorghum are located in a different set...
Introduction The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a very high resolution near infrared spectrometer currently orbiting Mars on board the Mars Reconnaissance Orbiter (MRO). Since each mineral has a unique spectral signature, it is possible to use the measurements from this instrument to identify minerals on the surface of Mars. This project describes a method[1] to...
BACKGROUND Acute-on-chronic liver failure (ACLF) is a life threatening acute decompensation of a pre-existing chronic liver disease. The artificial liver support system MARS is a new emerging therapeutic option possible to be implemented in routine care of these patients. The medical efficacy of MARS has been demonstrated in first clinical studies, but economic aspects have so far not been inve...

On June 19, 1976, the Viking 1 Orbiter achieved orbital insertion around Mars. On July 20, the Viking 1 Lander soft-landed on the surface of Mars in the Chryse Planitia (22 degrees north, 48 degrees west) becoming the first human-made object to land on Mars. The Viking 2 Orbiter achieved Mars orbital insertion on August 7. On September 3, the Viking 2 soft-landed in Utopia Planitia (44 degrees ...
Experiments were conducted in a Mars simulation chamber (MSC) to characterize the survival of endospores of Bacillus subtilis under high UV irradiation and simulated martian conditions. The MSC was used to create Mars surface environments in which pressure (8.5 mb), temperature (-80, -40, -10, or +23 degrees C), gas composition (Earth-normal N2/O2 mix, pure N2, pure CO2, or a Mars gas mix), and...
AIMS The aims of this study were to compare the diagnostic test characteristics of ultrasound alone, metal artefact reduction sequence MRI (MARS-MRI) alone, and ultrasound combined with MARS-MRI for identifying intra-operative pseudotumours in metal-on-metal hip resurfacing (MoMHR) patients undergoing revision surgery. METHODS This retrospective diagnostic accuracy study involved 39 patients ...
