L‐Quebrachitol Enhances Sedative Effect of Diazepam Through GABAergic Pathway: Animal and Computational Studies

Brain and Behavior, Volume 16, Issue 1, January 2026.
L‐quebrachitol (LQL) significantly enhanced the sedative effects of diazepam in thiopental sodium‐induced chicks by reducing sleep latency and prolonging duration. Molecular docking revealed LQL's interaction with GABAA receptor (α1 and β2 subunits), supporting a GABAergic mechanism and highlighting its potential as a safe, natural sedative agent ...

High metabolic sensitivity to hot drought in two declining pine species with constrained physiology

Functional Ecology, Volume 40, Issue 1, Page 239-255, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decline syndromes preceding tree mortality under increased abiotic stress often include reductions in transpiring leaf area and tree growth. However, the mechanisms regulating the metabolism and physiology of declining trees before they cross irreversible thresholds in ...

Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

Geobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

A Brief History of Plastic Additives. Part 1: Antioxidants

Macromolecular Materials and Engineering, Volume 310, Issue 8, August 2025.
The development of suitable antioxidants has been a decisive element for the success of plastics in particular in the field of polyolefins. Sterically hindered phenol structures, amines, and sulfur‐containing products including multifunctional substances comprise today´s commercial range. Stabilizers based on renewable resources and tailor‐made systems

Cyclitols. XXVI. The solvolysis of tosylinositols in acetic acid

, 1967
Several monotosyl derivatives of inositols have been solvolysed in boiling acetic acid. In some cases the reaction occurs with predominant inversion and then presents a method suitable for the synthesis of rare cyclitols, e.g., allo- and muoo- inositols ...
