Residual Chemical Shift Anisotropies in the Structure Determination of Small Molecules

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 286-311, March 2026.
Plasma neutrophil elastase(ELANE) was markedly elevated in patients with alcohol use disorder, indicating a dysregulated protease‐antiprotease inflammatory balance characterised by decreased SERPINA3. ELANE showed excellent diagnostic specificity(AUC = 0.8683), supporting its potential utility as a neuroinflammatory biomarker for AUD.

Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters

The Influence of Climate and Livestock Grazing on Two Species of Burrowing Desert Frogs

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Frogs are one of the most vulnerable groups of vertebrates globally, occupying a range of environments including arid deserts. They are threatened by many interacting factors, including climate change and livestock grazing. In this study, we present the first long‐term research (over 30 years) on two arid‐dwelling frogs in Australia, the ...
