¹H-NMR serum metabolomic profiling from clinical routine identifies signatures of progressive melanoma metastasis [PDF]

Scientific Reports
Early detection of active melanoma metastasis is crucial. Serum metabolomics may offer non-invasive biomarkers, but real-world applicability needs validation. This study aimed to identify ¹H-NMR-based serum metabolic signatures for active metastasis in a

GC-MS-based metabolomics for the detection of adulteration in oregano samples [PDF]

Journal of the Serbian Chemical Society, 2021
Oregano is one of the most used culinary herb and it is often adulterated with cheaper plants. In this study, GC–MS was used for identification and quantification of metabolites from 104 samples of oregano (Origanum vulgare and O.

Genetic Changes Driving Immunosuppressive Microenvironments in Oral Premalignancy

Frontiers in Immunology, 2022
Oral premalignant lesions (OPLs) are the precursors to oral cavity cancers, and have variable rates of progression to invasive disease. As an intermediate state, OPLs have acquired a subset of the genomic alterations while arising in an oral inflammatory

Aperiodicity, Star-freeness, and First-order Logic Definability of Operator Precedence Languages [PDF]

Logical Methods in Computer Science, 2023
A classic result in formal language theory is the equivalence among non-counting, or aperiodic, regular languages, and languages defined through star-free regular expressions, or first-order logic.

Novel Kernel Orthogonal Partial Least Squares for Dominant Sensor Data Extraction

IEEE Access, 2020
Orthogonal Partial Least Squares (OPLS) methods are aimed at finding the dominant factors from predictor variables that can maximize cross-covariance between the factors themselves and response variables while a high correlation between them should also ...

Improved predictions of nonlinear support vector regression and artificial neural network models via preprocessing of data with orthogonal projection to latent structures: A case study

Bulletin of Faculty of Pharmacy Cairo University, 2017
In the presented study, orthogonal projection to latent structures (OPLS) is introduced as a data preprocessing method that handles nonlinear data prior to modelling with two well established nonlinear multivariate models; namely support vector ...
