The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Effects of Summer Heat Stress on Physiological Parameters and Reproductive Efficiency of Barbarine Ewes Under Natural Outdoor or Indoor Conditions

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Climate change and rising ambient temperatures increasingly challenge sheep production systems in arid and semi‐arid regions, particularly during the summer breeding season. This study evaluated the effects of heat stress and direct solar exposure on physiological responses, metabolic profile, and reproductive performance of Barbarine ewes, a ...

The activity of the Pseudomonas aeruginosa virulence regulator sVreI is modulated by the anti-s factor VreR and the transcription factor PhoB

Frontiers in Microbiology, 2016
Gene regulation in bacteria is primarily controlled at the level of transcription initiation by modifying the affinity of the RNA polymerase (RNAP) for the promoter. This control often occurs through the substitution of the RNAP sigma () subunit.

Improving nutritional assessment in pediatric anorexia nervosa: Clinical value of key serum biomarkers

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Reliable biochemical markers of starvation are needed to improve detection and monitoring of starvation in pediatric anorexia nervosa (AN), thus we explored new and revisited old potential serum biochemical markers. Methods In this prospective cohort study we included 65 pediatric patients with AN.
