Long‐Term Low‐DO Operation Changes the Ammonia Oxidizer Community and Oxygen Kinetics

Water Environment Research, Volume 98, Issue 10, October 2026.
Lower dissolved oxygen reduces energy demand for wastewater treatment but slows ammonia removal. This study investigates a pilot process maintaining complete nitrification, documenting ammonia oxidizer adaptation to low dissolved oxygen. ABSTRACT Low–dissolved oxygen (DO) biological nutrient removal is an attractive option for energy and cost reduction,

The different responses of AOA and AOB communities to irrigation systems in the semi-arid region of Northeast China [PDF]

Ammonia oxidation is the rate-limiting step in nitrification and the key step in the nitrogen (N) cycle. Most soil nutrients and biological indicators are extremely sensitive to irrigation systems, from the perspective of improving soil fertility and ...

Unraveling the Evolution of Silicic Volcanism in a Distributed Volcanic Field: Insights From Harrat Khaybar, Western Saudi Arabia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Diversity, abundance and niche differentiation of ammonia-oxidizing prokaryotes in mud deposits of the eastern China marginal seas

Frontiers in Microbiology, 2016
The eastern China marginal seas are prominent examples of river-dominated ocean margins, whose most characteristic feature is the existence of isolated mud patches on sandy sediments.

The histone deacetylase inhibitor, suberoylanilide hydroxamic acid, restores blood–brain barrier integrity in a human stem cell‐based model of ischaemic stroke

British Journal of Pharmacology, Volume 183, Issue 19, Page 5791-5812, October 2026.
Ischaemic stroke is characterised by acute cerebrovascular occlusion and blood–brain barrier (BBB) breakdown. Our results indicated that the histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) ameliorated the loss of BBB integrity, changed the morphology of brain endothelial cells, increased the level of basement membrane and ...

Impacts of Species Introductions on the Trait Diversity of Interacting Avian Frugivores and Fleshy‐Fruited Plants Depend on Native Trait Diversity

Global Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Aim The introduction of non‐native species to native ecological communities by humans is a major driver of global biodiversity change. Studying how species introductions influence interacting species is essential to understanding possible functional consequences of global change because biotic interactions are ecologically crucial.

Long-Term Management of Hepatitis C-Seropositive Subjects with AntiOxidant Biofactor (AOB®), a Fermented Food Supplement [PDF]

, 2010
The efficacy of AntiOxidant Biofactor (AOB(R)) for the management of apparently healthy subjects with chronic hepatitis C infection was investigated. A total of 60 subjects (35 males, 25 females) participated in the trial. AOB was given orally in 2 packs
