The paper has examined various aspects of the singular spectrum analysis (SSA) method.The original purpose of the method is to optimize harmonic (spectral) analysis of time series.A theoretical justification based on integral equations was given for the SSA.A solution to the problem of large dimensionality of the autocovariance matrix (AM) was prop
Detection of Morphine and Opioids in Fingernails: Immunohistochemical Analysis and Confirmation with Ultra-High-Performance Liquid Chromatography Coupled with High-Resolution Mass Spectrometry
This study aimed to investigate the detection of morphine in fingernails from forensic autopsies using immunohistochemistry (IHC), with confirmation by ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC-HRMS).A primary antibody specific to morphine and a secondary antibody conjugated to horseradish pe
Differential expression patterns of purinergic ectoenzymes and the antioxidative role of IL-6 in hospitalized COVID-19 patient recovery
IntroductionWe have acquired significant knowledge regarding the pathogenesis of severe acute respiratory syndrome caused by coronavirus 2 (SARS-CoV-2).However, the underlying mechanisms responsible for disease recovery still need to be fully understood.MethodsTo gain insights into critical immune markers involved in COVID-19 etiopathogenesis, we s
