Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

ChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

High‐Resolution Ion Mobility as an Alternative to Quadrupole‐Based Precursor Isolation for Reducing Chimeric Fragmentation Spectra in Bottom‐Up Proteomics

PROTEOMICS, EarlyView.
ABSTRACT To assess the potential for high resolution ion mobility (HRIM) as an alternative means of precursor isolation for mass spectrometry fragmentation analysis we performed a meta‐analysis of predicted tryptic peptide features from the human proteome to measure the rate of chimeric spectrum generation relative to traditional quadrupole‐based ...
