Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Quantifying surface water evaporation loss rates in the Manas River Basin using stable isotope tracers

Hydrology Research
Calculating evaporation loss rates of surface water poses a significant challenge in remote regions, where meteorological data are scarce. To address this challenge, our study has adopted stable isotope tracers to determine the loss rates within the ...

Influence of THF as Internal‐Donor on Ziegler‐Natta Polyethylene Catalysts

Macromolecular Reaction Engineering, EarlyView.
Ziegler–Natta catalysts remain widely applied due to robustness, handling ease, and cost‐effectiveness. To support further optimization, we examine how internal donors such as tetrahydrofuran influence catalyst performance and polymer characteristics.

Notoginsenoside R2 Antagonizes Renal Interstitial Fibrosis by Regulating Fatty Acid Oxidation via the CASP2/ALDH3A1 Axis

Phytotherapy Research, EarlyView.
Proposed mechanism by which notoginsenoside R2 (NGR2) attenuates renal interstitial fibrosis. In injured renal tubular epithelial cells, CASP2 downregulation and enhanced ubiquitin‐dependent degradation of ALDH3A1 disrupt mitochondria‐associated endoplasmic reticulum membranes (MAMs) and impair fatty acid oxidation (FAO), leading to lipid accumulation ...

The Pivotal Role of Evaporation in Lake Water Isotopic Variability Across Space and Time in a High Arctic Periglacial Landscape

Water Resources Research
Rapidly changing climate is disrupting the High Arctic's water systems. As tracers of hydrological processes, stable water isotopes can be used for high quality monitoring of Arctic waters to better reconstruct past changes and assess future ...

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Late Glacial summer paleohydrology across Central Europe

Scientific Reports
It is generally accepted that a weakening of the North Atlantic thermohaline circulation caused the Younger Dryas cooling. Although the role of seasonality was emphasized previously, this aspect is rarely considered yet, and it remains elusive how this ...
