Orphan response regulator NnaR is critical for nitrate and nitrite assimilation in Mycobacterium abscessus

open access: yesFrontiers in Cellular and Infection Microbiology
Mycobacterium abscessus (Mab) is an opportunistic pathogen afflicting individuals with underlying lung disease such as Cystic Fibrosis (CF) or immunodeficiencies.

Rainfall and Substrate Origin Driven Change of Ruminant Manure Microbiomes in Cyprus

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Simulated rainfall triggered strong ecological filtering in ruminant manures, overriding substrate‐driven differences between dairy cow and goat manure. While the more fibrous goat manure supported higher initial microbial diversity, rewetting led to community convergence dominated by spore‐forming bacteria. Enrichment of sporulation (spmA, spmB, ytfJ)

Biofloc‐based aquaculture: From monoculture to integrated systems

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract The demand for high‐quality protein has been growing in recent years, led by population growth. The development of aquaculture has been considered one of the solutions to ensure food security worldwide. New farming technologies have been promoted to increase productivity and, at the same time, minimize environmental impacts.

Role of p38 activation in changes of nitric oxide production in rat biceps femoris muscle during metabolic syndrome

open access: yesСучасні медичні технології
Transcriptional changes in organism and muscles especially during development of metabolic syndrome (MetS) is still highly understudied. Role of p38 MAPK activation during MetS is highly debatable.

Effects of dietary nitrate supplementation on peak oxygen uptake following 10 days of Ramadan fasting in healthy adults

open access: yesExperimental Physiology, Volume 111, Issue 10, Page 4636-4645, 1 October 2026.
Abstract Ramadan is a sacred religious practice observed by Muslims that involves abstaining from food and water from sunrise to sunset for 1 month. Prior work has reported that peak oxygen uptake (V̇O2peak${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{peak}}}}$) can decline during Ramadan in parallel with reduced physical activity.

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

open access: yesChemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
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.

Interaction of nitrite with alkali oxides

open access: yes, 2002
The structural and electronic properties of nitrite (ONO) and alkali oxides (OX; X = H, Li, Na, K) have been investigated theoretically by performing ab initio calculations in the HF level. These species form alkali-metal nitrates (ONOOX).

Structures of genes nasA and nasB, encoding assimilatory nitrate and nitrite reductases in Klebsiella pneumoniae M5al

open access: yes, 1993
Kiebsiella pneumoniae can use nitrate and nitrite as sole nitrogen sources during aerobic growth. Assimilatory nitrate and nitrite reductases convert nitrate through nitrite to ammonium.
