Nitrite-oxidizing bacteria (NOB) represent a crucial node in the global nitrogen cycle. By catalyzing the second step of nitrification-the oxidation of nitrite to nitrate to generate energy for growth-NOB activity controls the fate of nitrite (NO(2)^(-)) in aerobic environments. Despite thriving in diverse environments, including soils, freshwater, marine ecosystems, subsurface habitats, and water treatment systems, organisms capable of nitrite oxidation are confined to Nitrobacter, Nitrospira,...

Misalignment between physicians and hospital administrators has long challenged US healthcare systems. The COVID-19 pandemic magnified these tensions, with physicians reporting increased burnout and administrators grappling with severe financial pressures. This narrative review synthesizes findings from peer-reviewed studies, national surveys, organizational case examples, and policy reports to evaluate physician-administrator relationships. The analysis identifies 6 thematic areas: shared...

Diffusion-weighted magnetic resonance imaging (DWI) analyzes water diffusion in tissues, indirectly reflecting cellular density and aiding tumor characterization. Our objective was to explore the utility of DWI in three topics: (i) differentiation of bone and soft tissue sarcomas with respect to tumor type/grade; (ii) correlation with chemotherapy response in Ewing's sarcoma and osteosarcoma; and (iii) differentiation of benign from malignant soft tissue and bone tumors. The aim of the review...

CONCLUSIONS: Over three-quarters of rats with otitis media/interna had concurrent respiratory disease and almost one-third had intracranial extension. Advanced imaging should therefore be considered in rats presenting with respiratory or neurological signs.
