Distal urethral obstruction in an eight‐week‐old colt with struvite urolithiasis

Equine Veterinary Education, Volume 38, Issue 3, Page e130-e136, March 2026.
Summary An 8‐week‐old Thoroughbred colt presented with acute colic signs. Physical examination and transcutaneous ultrasound of the abdomen and penis revealed a urinary tract obstruction in the distal urethra due to urolithiasis. A distal urethrotomy over the site of obstruction was performed to remove the urolith and relieve the obstruction.

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, Volume 293, Issue 6, Page 1643-1663, March 2026.
Understanding the molecular basis of nitrogen fixation is essential for engineering bacteria that fulfill the nitrogen demand of crop plants, reducing our reliance on synthetic nitrogen fertilizers. The bacterial two‐component system comprising the anti‐activator protein (NifL) and the Nif‐specific transcriptional activator (NifA) controls the nitrogen

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

The FEBS Journal, Volume 293, Issue 6, Page 1616-1620, March 2026.
The urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as
