Lung Cancer Breath Test in Clinical Trial
The University of Leicester and Glenfield Hospital in Leicester, UK, are starting a clinical trial into a gas chromatography–field asymmetric ion mobility spectrometry sensor (Owlstone Nanotech Ltd.) for the detection of early-stage lung cancer.
The University of Leicester and Glenfield Hospital in Leicester, UK, are starting a clinical trial into a gas chromatography–field asymmetric ion mobility spectrometry sensor (Owlstone Nanotech Ltd.) for the detection of early-stage lung cancer. Dr Salman Siddiqui, a clinical senior lecturer and adult chest physician at the University of Leicester and Leicester’s Hospitals, said: “Lung cancer has one of the lowest 5-year survival rates of all cancers; however, early diagnosis can greatly improve a patient’s prognosis. Current diagnostic procedures such as a chest X-ray, CT scan, and bronchoscopy are costly and not without risks so the benefits of a non-invasive, cheaper alternative are clear.”

University of Rouen-Normandy Scientists Explore Eco-Friendly Sampling Approach for GC-HRMS
April 17th 2025Root exudates—substances secreted by living plant roots—are challenging to sample, as they are typically extracted using artificial devices and can vary widely in both quantity and composition across plant species.
Determining the Serum Proteomic Profile in Migraine Patients with LC–MS
April 17th 2025Researchers used liquid chromatography–mass spectrometry (LC–MS) in their proteomic analysis to compare the serum proteome of migraine patients with healthy controls and to identify differentially expressed proteins as potential migraine biomarkers.
