QUANTITATION OF NON-DERIVATIZED FREE AMINO ACIDS FOR DETECTING INBORN ERRORS OF METABOLISM BY INCORPORATING MIXED-MODE CHROMATOGRAPHY WITH TANDEM MASS SPECTROMETRY

Introduction: Amino acids are critical biomarkers for many inborn errors of metabolism, but amino acid analysis is challenging due to the range of chemical properties inherent in these small molecules.Techniques are available for amino acid analysis, but they can suffer from long run times, laborious derivatization, and/or poor resolution of isobar

Masers once represented the state of the art in low-noise microwave amplification technology but eventually became obsolete due to their need for cryogenic cooling.Masers based on solid-state spin systems perform most effectively as amplifiers, since they provide a large density of spins and can, therefore, operate at relatively high powers.While s

In this study, we determined the complete mitochondrial genome sequence of click beetle Chiagosnius sulcicollis (Candeze, 1878) (GenBank accession no.MK792747) using next-generation sequencing (NGS) method.The mitogenome is 15,848 bp in length, consisting of 13 protein-coding Universal Remote Control genes (PCGs), 2 ribosomal RNA genes, 22 transfer

Investigations of music in everyday life are dominated by a functional perspective, drawn from work using the theory of Uses and Gratifications.In so doing, we may have neglected to fully appreciate the value people place on music listening.Therefore, the present study considered if, and why, people value Swim - Womens Suits - Competitive music lis
