Mechanistic Insights into Alzheimer’s Disease Unveiled through the Investigation of Disturbances in Central Metabolites and Metabolic Pathways [PDF]

open access: yesBiomedicines, 2021
Hydrophilic metabolites are closely involved in multiple primary metabolic pathways and, consequently, play an essential role in the onset and progression of multifactorial human disorders, such as Alzheimer’s disease.

Gas-liquid chromatography-mass spectrometry of synthetic ceramides

open access: hybridJournal of Lipid Research, 1969
Two series of ceramides with either sphingosine (sphing-4-enine) or sphinganine as base and with one of the saturated fatty acids C16, C18, C20, C22, C24, C26, or oleic acid were analyzed as the 1,3-di-O-trimethylsilyl ether derivatives by gas ...

Peak Alignment of Gas Chromatography-Mass Spectrometry Data with Deep Learning [PDF]

open access: yesarXiv, 2019
We present ChromAlignNet, a deep learning model for alignment of peaks in Gas Chromatography-Mass Spectrometry (GC-MS) data. In GC-MS data, a compound's retention time (RT) may not stay fixed across multiple chromatograms. To use GC-MS data for biomarker discovery requires alignment of identical analyte's RT from different samples.

Quantifying Isoprenoids in the Ergosterol Biosynthesis by Gas Chromatography–Mass Spectrometry [PDF]

open access: yesJournal of Fungi, 2023
The ergosterol pathway is a promising target for the development of new antifungals since its enzymes are essential for fungal cell growth. Appropriate screening assays are therefore needed that allow the identification of potential inhibitors.

Detection of Urethane in Non-alcoholic Fermented Food [PDF]

open access: yesE3S Web of Conferences, 2020
Among fermented foods, urethane often appears, which is a “2A” grade carcinogen. There are many types of fermented foods in my country, and the detection methods are not uniform enough, and no specific urethane detection standards have been formed.
