Uncovering Hidden Contaminants in Human Milk: Non-Targeted Biomonitoring with SIRIUS

Human milk is the ideal source of nutrition for infants, but growing concerns exist about the presence of chemical contaminants that can find their way into it. For years, scientists have relied on targeted analysis, a method that can only find what they are already looking for. In this non-targeted approach utilizing SIRIUS, researcher successfully identify common and previously unreported chemical contaminants and gain a more comprehensive understanding of the chemical exposures mothers and infants face.

Detecting pharmaceuticals and their transformation products with SIRIUS

Pharmaceutical pollution poses risks to ecosystems and human health, yet traditional annotation methods often miss transformation products—drug breakdown compounds that may be even more persistent. We demonstrate how SIRIUS enhances annotation of pharmaceuticals in Luxembourgish rivers, from precursor drug screening to transformation product screening. Our approach for environmental monitoring is relevant not only for pharmaceuticals but also for pesticides and industrial chemicals, whose degradation products may have significant environmental impacts.

Screening extractables and leachables with SIRIUS: Plastic-related contaminants in liquor products

In a world where we’re becoming increasingly conscious of what we consume, understanding the potential presence of unexpected extractables and leachables in our food and drinks is paramount. Alcoholic beverages are of particular concern due to their increased affinity and extended storage periods. A non-targeted approach to analysis is essential for uncovering both known and unknown contaminants in our drinks. By analysing fragmentation patterns, SIRIUS predicts chemical structures of unknowns to identify unexpected contaminants and ensure safety of our food.

Ketamine distribution in the brain: understanding drug metabolism with SIRIUS

Ketamine is known for its dual role as an anesthetic and an emerging antidepressant. Despite its long-standing clinical use, the metabolic pathways and pharmacokinetics of ketamine remain poorly understood. A study of ketamine metabolism in the pig brain using SIRIUS provides valuable insights into the distribution of ketamine and its metabolites in different areas of the brain.

Quality control using SIRIUS: nutrient profiles of Spirulina and co

Microalgae, such as Spirulina, are promising sources of sustainable nutrition with rich nutrient profiles. Ensuring consistent quality of microalgae as dietary supplements requires a quality control method reporting about their chemical composition. Mass spectrometry-based metabolomics coupled with SIRIUS helps identifying primary and secondary metabolites with potential health benefits, including free fatty acids, polar lipids, and pigments.

Hydrate your skin with “biotics”: Understanding the impact of pre/postbiotics on skin health

Our skin, beyond being a physical barrier, hosts a diverse community of microorganisms known as the skin microbiota. “Biotics” have gained attention for their potential to enhance the skin’s health, though their exact mode of action is still unclear. MS-based metabolomics has emerged as a powerful tool to characterize the chemical composition of the skin surface and correlate it with microbial communities. Using CSI:FingerID, researchers identified changes in the skin metabolome that are more pronounced than changes in the microbial composition, suggesting that even subtle shifts in microbial abundance can lead to significant effects on the skin.

Befriend your competitor: SIRIUS identifies metabolite linked to dual-species biofilm pathogenesis in cystic fibrosis

In the world of microbiology, there’s an ongoing battle between different bacterial species competing for survival and dominance. However, under certain conditions, two species can actually thrive together in a dual-species biofilm. The cooperation between P. aeruginosa and S. aureus in cystic fibrosis leads to increased disease severity. But so far, only little is known about the chemical communication mechanisms between those bacteria. SIRIUS identifies a metabolite that could be related to the increased pathogenesis of this dual-species biofilm in cystic fibrosis.
