[Determination of diazepam in aquatic products by ultra performance liquid chromatography-tandem mass spectrometry with pass-through solid phase extraction].
Se pu = Chinese journal of chromatography
Jul 8, 2020
A method was developed for the determination of diazepam in aquatic products by pass-through solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The analyte was extracted with acetonitrile directly an...
Integration of ultra-high-pressure liquid chromatography-tandem mass spectrometry with machine learning for identifying fatty acid metabolite biomarkers of ischemic stroke.
Chemical communications (Cambridge, England)
Jun 18, 2020
We report for the first time the integration of ultra-high-pressure liquid chromatography-tandem mass spectrometry with machine learning for identifying fatty acid metabolite biomarkers of ischemic stroke. In particular, we develop an optimal model t...
[Simultaneous determination of five baicaleins in healthy product tablets by dispersive solid-phase extraction-high performance liquid chromatography-tandem mass spectrometry].
Se pu = Chinese journal of chromatography
Jun 8, 2020
A method based on dispersive solid-phase extraction-high performance liquid chromatography-tandem mass spectrometry (DSPE-HPLC-MS/MS) was developed for the simultaneous determination of five analytes scutellarein, 4'-hydroxywogonin, norwogonin, baica...
A Community-Based Study Identifying Metabolic Biomarkers of Mild Cognitive Impairment and Alzheimer's Disease Using Artificial Intelligence and Machine Learning.
Journal of Alzheimer's disease : JAD
Jan 1, 2020
BACKGROUND: Currently, there is no objective, clinically available tool for the accurate diagnosis of Alzheimer's disease (AD). There is a pressing need for a novel, minimally invasive, cost friendly, and easily accessible tool to diagnose AD, assess...
Chemical composition and antioxidant, cytotoxic, and insecticidal potential of Valeriana alliariifolia in Turkey.
Arhiv za higijenu rada i toksikologiju
Sep 1, 2019
Valeriana is a common plant species used for various healing purposes in folk medicine since antiquity. This study investigates the phytochemical profile, antioxidant, cytotoxic, and insecticidal activity of Valeriana alliariifolia Adams, a species t...
Deciphering complex metabolite mixtures by unsupervised and supervised substructure discovery and semi-automated annotation from MS/MS spectra.
Faraday discussions
Aug 15, 2019
Complex metabolite mixtures are challenging to unravel. Mass spectrometry (MS) is a widely used and sensitive technique for obtaining structural information of complex mixtures. However, just knowing the molecular masses of the mixture's constituents...
[Determination of 4 kinds of plant growth regulator in bean sprout by solid phase extraction column coupled with ultra-high performance liquid chromatography].
Wei sheng yan jiu = Journal of hygiene research
Sep 1, 2017
OBJECTIVE: A method for the determination of 6-benzylaminopurine( 6-BAP), isopentennyladenine( z-IP), 4-fluorophenoxyacetic acid( 4-FPA), 4-chlorophenoxyacetic acid( 4-CPA) in bean sprout was developed using solid phase extraction column with ultra-h...
DiagnoProt: a tool for discovery of new molecules by mass spectrometry.
Bioinformatics (Oxford, England)
Jun 15, 2017
MOTIVATION: Around 75% of all mass spectra remain unidentified by widely adopted proteomic strategies. We present DiagnoProt, an integrated computational environment that can efficiently cluster millions of spectra and use machine learning to shortli...
Comparative study between UHPLC-UV and UPLC-MS/MS methods for determination of alogliptin and metformin in their pharmaceutical combination.
Die Pharmazie
Feb 1, 2017
A new UPLC-MS/MS method (method A), for simultaneous determination of alogliptin (ALN) and metformin (MET) in their recently approved pharmaceutical combination Kazano® tablets, was developed and compared to a new UHPLC-UV method (method B). Concerni...
