Analytical Challenges in Detecting New Psychoactive Substances in Anti‐Doping: A Proof‐of‐Concept Involving Pentedrone Metabolite

open access: yesDrug Testing and Analysis, Volume 18, Issue 4, Page 530-536, April 2026.
The paper describes an investigation related to the pentedrone norephedrine metabolite. The athlete's sample was analyzed using ultra‐performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). According to the literature, this metabolite may originate from pentedrone, α‐pyrrolidinopentiophenone (PVP), or N‐ethylpentedrone (NEP).

Validity of Bioelectrical Impedance Analysis for the Assessment of Body Composition in Patients With Systemic Sclerosis

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Systemic sclerosis (SSc) is an autoimmune disease characterized by vasculopathy and progressive fibrosis. Reduced muscle mass is common and contributes to myopenia, sarcopenia and adverse clinical outcomes. Dual‐energy X‐ray absorptiometry (DXA) is the most widely used method in clinical research and is recommended by international ...

Perovskite Electrocatalysts for Oxygen Evolution in Alkaline Media: From Fundamentals to Recent Developments

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Perovskite oxides offer exceptional structural flexibility, enabling precise tuning of composition and electronic structure. This review connects these design parameters to both adsorbate‐ and lattice‐oxygen‐mediated OER pathways, highlighting the promise of rationally engineered perovskites as high‐performance electrocatalysts for alkaline water ...

Growth Response of Crop Legumes to Soil Microbiota Is Linked With Soil Nutrients and Planting History

open access: yesPlant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT Soil microbiota provide essential services to plants, but predicting or manipulating these benefits is difficult. Here, we investigated microbial benefits to legume crops at a landscape level to uncover factors that predict those services and can be modified by growers.

Breeding cold‐tolerant Orius laevigatus lines improves thermal tolerance and body size: implications for biological control

open access: yesPest Management Science, Volume 82, Issue 4, Page 3011-3018, April 2026.
Biological control agents performance is influenced by temperature. Two cold‐tolerant lines of O. loevigatus were developed, improving their fitness at both low and high temperatures, offering advantages far augmentative biological control. Abstract BACKGROUND The performance of biological control agents (BCAs) is strongly influenced by environmental ...
