Protocol for the Preparation of Polyphenols‐Polysaccharide Nanoparticles
ABSTRACT Polyphenols, natural compounds abundantly distributed in plants, possess potent antioxidant and anti‐inflammatory activities and hold promising potential in cardiovascular protection and the management of metabolic disorders. Nevertheless, their intrinsic instability and low bioavailability severely constrain their practical and large‐scale ...

XSPH‐I exhibits excellent cellular antioxidant activity and cell protective effects. Four novel antioxidant peptides were screened from XSPH‐I peptide, and the newly synthetic peptide exhibits excellent antioxidant properties in vitro. ABSTRACT In this study, the antioxidant peptides (XSPH) from Xanthoceras sorbifolium oleifera were extracted and ...

Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Protein glycosylation in lung cancer from a mass spectrometry perspective
Abstract Lung cancer is a severe disease for which better diagnostic and therapeutic approaches are urgently needed. Increasing evidence implies that aberrant protein glycosylation plays a crucial role in the pathogenesis and progression of lung cancer.

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

A Perspective of Multi‐Reflecting TOF MS
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.
