Population shifts in the activated sludge microbiome of a membrane bioreactor (MBR) during the treatment of Ramen noodle-soup wastewater were analyzed by high-throughput sequencing. An MBR underwent stable treatment of wastewater containing increasing oil concentrations (from 135 to 1,350 mg/L) for 26 days; however, after feeding with wastewater containing 2,700 mg/L of oil, the mixed liquor suspended solids and transmembrane pressure exhibited gradual and rapid increases, respectively, leading to clogging of the membrane. Phylogenetic analysis revealed an oil supply-dependent increase in the abundance of Cupriavidus gilardii (relative abundance of 26.

- - The text discusses the importance of quality control in transplant tissues and organs to ensure their safety and effectiveness for regenerative medicine, noting current limitations in evaluation methods due to their invasive nature.
- - Researchers investigated the use of a non-invasive technique, [F]FDG-bioradiography, to measure tissue safety and effectiveness by examining [F]FDG uptake, which correlates with cell viability and metabolism in a reconstructed human epidermal model.
- - Findings showed that [F]FDG uptake varied under different conditions (like hypothermia and hypoxia) and aligned with DNA content and histological assessments, suggesting that [F]FDG-bioradiography could serve as a viable non-invasive test for evaluating transplant tissue quality.*
