Oxygen inhibition of nitrate uptake is a general regulatory mechanism in nitrate respiration.

Journal of Biological Chemistry, 1988
It has recently been demonstrated that oxygen inhibits nitrate uptake by denitrifying Pseudomonas aeruginosa. The purpose of the present investigation was to determine if this novel mechanism of regulation is universal for the regulation of nitrate respiration in other widely divergent species of bacteria.

Hijacking anaerobic metabolism to restore antibiotic efficacy in Pseudomonas aeruginosa

Applied and Environmental Microbiology
Bacterial pathogens regularly encounter oxygen (O2) limitation at sites of infection in the human body. Many pathogens exhibit antibiotic recalcitrance under low O2 conditions, spotlighting the need for new therapeutics that are effective in O2-limited ...

Mr BMT Achieves Systemic Macrophage Replacement With Preservation of Tissue Homeostasis

Advanced Science, EarlyView.
Microglia replacement by bone marrow transplantation (Mr BMT) enables systemic replacement of tissue‐resident macrophages. Despite persistent macrophage and tissue remodeling across multiple organs, core biological functions and innate immune responses remain preserved, supporting long‐term maintenance of organismal homeostasis and the therapeutic ...

Time‐Multiplexed Organic Electrochemical Transistor for Saliva‐Based Rapid Detection of Viral Proteins

Advanced Science, EarlyView.
A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Measuring nitrogen loss from denitrification

California Agriculture, 1977
Denitrification is the biological reduction of nitrate and nitrite to volatile gases, usually nitrous oxide or molecular nitrogen, or both. Denitrification is accomplished by bacteria capable of using nitrate in place of oxygen.
