MetabolomicsPrediction, detection, and validation of isotope peaks in mass spectrometry data (Supplemental data for manuscript)
Mass spectrometry is a key analytical platform for metabolomics. The precise quantification and identification of small molecules is a prerequisite for elucidating the metabolism and the detection, validation, and evaluation of isotope clusters in LC-MS data is important for this task. Here, we pres...

MetabolomicsA benchmark spike-in data set for biomarker identification in metabolomics
The development and the validation of innovative approaches for biomarker selection are of paramount importance in many -omics technologies. Unfortunately, the actual testing of new methods on real data is difficult, because in real data sets, one can never be sure about the “true” biomarkers. In th...

MetabolomicsDIAMetAlyzer allows automated false-discovery rate-controlled analysis for data-independent acquisition in metabolomics
The extraction of meaningful biological knowledge from high-throughput mass spectrometry data relies on limiting false discoveries to a manageable amount. For targeted approaches in metabolomics a main challenge is the detection of false positive metabolic features in the low signal-to-noise ranges ...

MetabolomicsDevelopment and verification of quality control guidelines for the utilization of lipidomic data
Metabolome data has been accumulating exponentially like other omics fields as the metabolomics field has grown and expanded to a remarkable level worldwide in the past 10 years. In line with this situation, it is necessary to establish a metabolomic data center and build and operate a global open p...

MetabolomicsDetection of adulteration in Iranian saffron samples by 1H NMR spectroscopy and multivariate data analysis techniques
Introduction: The high market value of saffron (Crocus sativus L.) has made it an attractive candidate for adulteration. Safflower (Carthamus tinctorius L.) and tartrazine are among the most common herbal and synthetic foreign materials that may be added to pure saffron for the purpose of adulterati...

TranscriptomicscaArray_jacob-00182: Gene expression-based survival prediction in lung adenocarcinoma: a multi-site, blinded validation study
Here we report a large, training*testing, multi-site, blinded validation study to characterize the performance of several prognostic models based on gene expression for 442 lung adenocarcinomas. The hypotheses proposed examined whether microarray measurements of gene expression either alone or combi...

MetabolomicsIntegrative Modeling of Quantitative Plasma Lipoprotein, Metabolic, and Amino Acid Data Reveals a Multiorgan Pathological Signature of SARS-CoV-2 Infection
The metabolic effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on human blood plasma were characterized using multi-platform metabolic phenotyping with Nuclear Magnetic Resonance (NMR) spectroscopy and liquid chromatography-mass spectrometry (LC-MS). Quantitative mea...

ProteomicsP-VIS: internally-controlled validation of mass spectrometry-based peptide identifications
Peptide-Spectrum Match (PSM) Validation with Internal Standards (P-VIS) is an objective approach to validating individual PSMs. A biological sample is analyzed by LC-MS/MS and the data are searched using a traditional approach such as a database search or de novo sequencing. A PSM of interest is ide...
