The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Establishment of a method for determining the origin of glutamic acid in processed food based on carbon and nitrogen stable isotope ratios

open access: yesHeliyon, 2019
We developed a discriminant method based on the stable isotope ratio of carbon and nitrogen (δ13C and δ15N) to evaluate whether monosodium glutamate (MSG) is used in processed food samples.

Microglial Activation Under Hypoxic Conditions in Early Alzheimer's Disease: Can Natural SIRT1 Activators Be Therapeutic Allies in the Inflammation–Energy Axis?

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by a preclinical stage that typically lasts for decades. Early on during this time, microglia react to pathological changes and become protective and even transiently delay neurodegeneration.

Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

open access: yesSustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Artificial light at night and invasive signal crayfish alter aquatic‐terrestrial food webs

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Resource flows across aquatic‐terrestrial boundaries are increasingly affected by multiple stressors, such as artificial light at night (ALAN) and aquatic invasive species, which can alter the availability of resources for consumers.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
