Quality decisions depend on more than instruments. Eurachem spotlights how pre- and post-analytical PT/EQA assess the full pathway—from sampling to interpretation—to drive quality and harmonisation. ISO 15189 stresses EQA should check the entire process, including pre- and post-examination.

• 🔍 Why it matters: reveals variation in sample prep, gaps vs guidelines, and inconsistent interpretation that routine PT can miss
• 🧪 Clinical chemistry: combine patient context + results; expert groups rank interpretative advice and share feedback
• 🧫 Microbiology (food poisoning): choose target organism(s), justify methods, report results, and decide on information dissemination
• 🧸 Toy safety: assess a sourced toy against EN 71; select clauses, tests, and labelling; compare with model answers
• 💧 Drinking water: evaluate near‑limit samples per Directive 98/83/EC; report results, uncertainty, and pass/fail; insights can inform regulators
• 🚀 Get started: find schemes via national accreditation bodies or EPTIS

Discover how pre- and post-analytical PT/EQA schemes improve the quality, harmonisation, and reliability of routine laboratory analyses.

What happens when glycoproteomics meets real-time LC-MS decision making? 🚀
At the University of Washington, Nick Riley and the Riley Group are unlocking cell-surface biology using the Thermo Scientific Orbitrap Ascend MultiOmics Tribrid Mass Spectrometer paired with the Vanquish Neo UHPLC. 🔬⚙️

• Real-time library search powers Autonomous Dissociation Type Selection—choosing ETD, HCD, PTCR, and high-mass on the fly to maximize insight from a single injection. ⏱️🧠
• Flexible, reproducible separations reveal precious, low-abundance glycopeptides and intact glycoproteins. 🧪🎯
• Applied to protein corona studies with SEER nanoparticles despite double enrichment and scarce material. 🧬🧲
• Training-first mindset: robust tools democratize ETD so students chase big biological questions. 🎓💡
• Riley’s path: Josh Coon’s lab (University of Wisconsin-Madison) → Carolyn Bertozzi’s lab (Stanford), fueling a tools-first approach. 🛠️
• Kayla Markuson (Riley Group) received the 2025 Thermo Scientific Quantitative Proteomics Research Grant Program. 🏆

“Technology should expand the questions we can ask”—and real-time decision making is doing exactly that.

Orbitrap Ascend and Vanquish Neo enable flexible glycoproteomics workflows with ETD, HCD, and real-time LC-MS decision making.

🧬 A rare genetic disorder in the Amish community has illuminated a core cellular checkpoint in RNA splicing!

• CEITEC Masaryk University uncovered a precisely timed “go” signal: a chemical modification of SF3B1 that enables SNIP1 to bind and let splicing proceed. ✅🔬
• First author Pavla Gajdušková explains that without this signal, the cell stalls splicing—blocking correct gene processing. 🧠
• In affected Amish children, a tiny change in SNIP1 weakens this response, causing splicing errors that impair nervous system development (e.g., muscle weakness, seizures). ⚠️
• Led by Dalibor Blažek and team, the study confirms the checkpoint’s validity and shows how subtle protein changes can derail cellular function. ✨
• Beyond rare disease, the mechanism may also influence cell division—relevant to cancer research. 🎗️

Published in Nature Communications with collaborators from Spain and Germany. 🌍

🧠🔬 New in J. Proteome Res.: CSF proteomics maps lysosomal and axonal disruptions in neurosyphilis
✍️ By Huayang Tang, Junjie Hu, Yifan Wu, Jinping Gao, Wenjun Wang, Xiaodong Zheng, Ran Zhang, Bo Liang, Fusheng Zhou, Ze Guo

• 🔬 Approach: LC–MS/MS discovery (28 individuals) + ELISA validation (110 samples) uncovered 234 differentially expressed CSF proteins
• 🧪 Pathways hit: lysosome (P = 0.007), axon guidance, neurodegeneration
• 📉 Key findings: Downregulated lysosomal proteins PSAP, DNASE2, CTSL, NPC2 and axonal protein EPHA4; strong PSAP–EPHA4 correlation (r = 0.83)
• ✅ Validation: Lower PSAP, DNASE2, CTSL, NPC2 confirmed in NS (n = 21) vs nNS (n = 56); ROC AUC—PSAP 0.91, DNASE2 0.95
• 🧬 Impact: Biomarker candidates and therapeutic clues; patterns align with signatures implicated in Alzheimer’s and Parkinson’s
• ⚠️ Limits: Cross-sectional design, limited ELISA panel; calls for longitudinal and mechanistic studies

A promising way to outsmart superbugs is here! 🧪🦠

• Led by Eva Kudová (IOCB Prague) and Jitka Viktorová (UCT Prague), researchers designed androstane-based steroid derivatives that turbocharge existing antibiotics. 🚀
• The best two molecules (compounds 13 and 16) block bacterial efflux pumps, slashing the doses needed for ciprofloxacin and erythromycin. 💊🔒
• One lead also suppresses Staphylococcus aureus virulence genes—hitting resistance and pathogenicity at once. 🧬🛡️
• Crucially, the most active compounds were non‑toxic to human immune cells and showed no detectable endocrine activity. ✅
• This positions steroidal scaffolds as potent antibiotic adjuvants to overcome efflux‑mediated resistance. 🔬

Authors: Daniela Brdová, Bára Křížkovská, Jan Špaček, Zdeněk Míchal, Eva Jablonská, Ondřej Strnad, Hana Chodounská, Eszter Szánti‑Pintér, Marina Morozovová, Václav Hanžl, Jan Tkadlec, Martijn Riool, Jan Lipov, Jitka Viktorová, Eva Kudová. Published in Eur. J. Med. Chem. (2026). 📄

Androstane-based steroids can improve antibiotic efficacy against multidrug-resistant Staphylococcus aureus by targeting efflux-mediated resistance.

💊 New way to track metformin adherence in type 2 diabetes—straight from blood! 🔬

• What’s new: Untargeted metabolomics/lipidomics revealed N‑lactoyl‑amino acids (e.g., N‑lactoyl‑phenylalanine) as dose‑responsive plasma biomarkers of metformin exposure 🩸
• Why it matters: Objective, ultra‑sensitive (nanomolar) “fingerprint” that distinguishes regular vs. irregular use; levels rise up to 7.2× in high‑exposure patients 🎯
• How it was done: 637 metformin‑treated patients + 143 controls; 614 metabolites annotated; strong correlations with metformin (ρ = 0.42–0.55) 📈
• Extra insights: T2D shows elevated lactate, organic acids, BCAAs; lipid remodeling with more saturated TAGs/DAGs and fewer cholesteryl esters, sphingomyelins, phospholipids 🧬
• Who’s behind it: Tomáš Čajka, Laboratory of Translational Metabolism, Institute of Physiology CAS, with the Institute for Clinical and Experimental Medicine in Prague and the West Coast Metabolomics Center (University of California, Davis) 🤝
• Read more: Clin Pharmacol Ther 119:1057–1069 🔗 https://doi.org/10.1002/cpt.70205

EU food safety is tightening under Regulation 396/2005 — with 259 audits in 2025 and a default MRL of 0.01 mg/kg, labs have zero room for error. In a new article, David Oliva (Organomation) explains why precise QuEChERS evaporation is the make-or-break step.

• 🔬 What it means: broader scope, precautionary principle, annual control programs, complex residue definitions
• 🧪 The challenge: matrix effects, recoveries 70–120%, LC-MS/MS + GC-MS/MS coverage
• 💨 The bottleneck: concentrating 1–6 mL acetonitrile to 0.2–1 mL without loss, degradation, or contamination
• 🌬️ Why nitrogen blowdown wins: ambient-temp operation, volatility control, reproducible endpoints, clean pathways
• ⚙️ How N-EVAP helps: precise temperature control, individual needle flow, inert wetted parts, scalable 6–45 positions, audit-ready documentation
• ✅ Compliance impact: tighter LOQs (≤0.01 mg/kg), ISO/IEC 17025 workflows, stronger proficiency test performance

Ready to fortify your QuEChERS workflow for EU 396/2005? Organomation’s N-EVAP turns evaporation into a reliable, high-throughput control point for results that stand up to European Commission scrutiny.
