Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

A new concept for controlling tiny-scale insect pest in green house – noval technology to apply liquid ethyl formate

open access: yesJulius-Kühn-Archiv, 2018
As increased agricultural insecticide uses and trends in insecticide resistance, increased labor cost to apply insecticide and limited its application to fertility season in green house.

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

open access: yesExperimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,

Engineering a Synthetic Formatotrophic Yeast With Enhanced Growth Capacity on Formate

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
Engineering Yeast for Growth on Formate and Methanol via Serine‐Centered C1 Coupling. By engineering serine metabolism and remodeling the rGly pathway, we rendered yeast growth strictly dependent on formate. This synthetic formatotrophy enables growth on dual‐C1 substrates by channeling formate into the central metabolism via serine deaminases and ...

Evaluation of Different Detection and Identification Methods of Intact Tetrahydro‐Methyltestosterone Sulfate Metabolites in Doping Control

open access: yesDrug Testing and Analysis, Volume 18, Issue 5, Page 678-689, May 2026.
The micro‐scale synthesis of the six out of eight possible tetrahydro‐methyltestosterone sulfate metabolites was performed, and the synthesized materials were used as analytical standards. The analysis of post‐administration sample extracts from methyltestosterone excretion studies against these standards provides further experimental proof for their ...

Detection of the Ammonium Ion in Space

open access: yes, 2013
We report on the detection of a narrow feature at 262816.73 MHz towards Orion and the cold prestellar core B1-bS, that we attribute to the 1(0)-0(0) line of the deuterated Ammonium ion, NH3D+.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.
