Microbial containment device: A platform for comprehensive analysis of microbial metabolism without sample preparation.

Metabolomics is a mainstream strategy for investigating microbial metabolism. One emerging application of metabolomics is the systematic quantification of metabolic boundary fluxes - the rates at which metabolites flow into and out of cultured cells. Metabolic boundary fluxes can capture complex metabolic phenotypes in a rapid assay, allow computational models to be built that predict the behavior of cultured organisms, and are an emerging strategy for clinical diagnostics.

Effect of cracks on the local deformations of articular cartilage.

Despite significant evidence regarding the increased risk of cartilage degeneration due to traumatic injuries to joints, there is still a lack of understanding of the mechanisms underlying osteoarthritis development following a joint injury. Injuries in knee cartilage are often characterized by lesions or tears. In addition to acute traumatic joint injuries, microscale damages, which may form because of wear, are thought to be a contributing factor in the development of osteoarthritis.
