Breathing new life into the critical oxygen partial pressure (Pcrit): a new definition, interpretation and method of determination

B. A. Seibel, A. Andres, M. A. Birk, A. Burns, C. T. Shaw, A. Timpe, C. Welsh

This paper redefines Pcrit as the oxygen partial pressure at which physiological oxygen supply is maximized, showing it correlates with existing Pcrit values and offers methodological advantages.

Gut bacteria convert cortisol into a distinct hostsignalling molecule

M. Freiberg, T. Wang, R. S. d. L. Rosa, A. Osswald, M. C. R. Melo, D. G. Stouffer, P. S. Buobu, C. Welsh, L. Yang, A. M. Abdel-Hamid, H. L. Doden, S. Devendran, R. M. Pollet, S. Goldberg, L. Ray, , J. M. Ridlon

The paper shows gut bacteria convert cortisol into 20-dihydrocortisol, a distinct host signalling molecule that reprograms colonic transcription and activates inflammatory pathways via NR4A3.

A widely distributed hydrogenase oxidises atmospheric H2 during bacterial growth

Z. F. Islam, C. Welsh, K. Bayly, R. Grinter, G. Southam, E. J. Gagen, C. Greening

This study investigates the role of group 2a [NiFe]-hydrogenase in three bacterial species, finding it supports aerobic H2 oxidation during growth and is widely distributed across 13 bacterial phyla.
