Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).

Researchers from KU Leuven explored two-dimensional liquid chromatography (2D-LC)’s application to profile micropollutants in wastewater.

In this first part of our interview with Ezgi Gürler of Females in Mass Spectrometry, we ask about her contributions to developing the glycoconjugate vaccine candidates (ExPEC Next Generation) at Johnson Vaccine and Prevention and the MultiResp RSV vaccine projects in Dalton Lab.

A study in Food Science & Nutrition evaluated the antioxidant and preservative effects of Epilobium angustifolium extract on beef burgers, finding that the extract influenced physicochemical properties, color stability, and lipid oxidation, with higher concentrations showing a prooxidant effect.

In this edition of the LCGC Blog, Amber Hupp of the College of the Holy Cross reflects on her childhood and talks about her journey recreating the scents from that long past.

Interest in applying artificial intelligence (AI) and machine learning (ML) to chromatography is greater than ever. In this article, we discuss data-related barriers to accomplishing this goal and how rethinking chromatography data systems can overcome them.

Microplastics and nanoplastics have been identified in the lungs of wild birds using laser direct infrared (LDIR) chemical imaging and pyrolysis gas chromatography–mass spectrometry (Py-GC–MS), in the first multi-species evidence of these plastics in bird lungs.
