Hsu WL, Chen CW, Liang HH, Chiang TL, Lin HW, Lin YH. Innovative analysis of diazepam, zolpidem and their main metabolites in human urine by micelle-to-solvent stacking in capillary electrophoresis. J Pharm Biomed Anal 2024; 239:115898. [PMID: 38064769 DOI: 10.1016/j.jpba.2023.115898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 01/05/2024]
Abstract
Diazepam and zolpidem are the most widely used medications for managing insomnia. However, significant concerns regarding the potential risks of misuse and abuse problems arose in many literatures. While urine analysis is a valuable diagnostic tool, a challenge arises from the fact that some parent drugs may remain undetectable in urine. This necessitates concurrent monitoring of their metabolites. Here, we described an innovative on-line sample preconcentration technique known as micelle to solvent stacking (MSS) for the analysis of diazepam, zolpidem, and their main metabolites in urine. Several key parameters warrant further discussion to optimize the MSS model, enhancing its performance in terms of sensitivity and resolution. After optimizing the conditions, we conducted a validation test, achieving high correlation coefficients (greater than 0.9977) for intra-day and inter-day regression lines. Additionally, both the relative standard deviation (RSD) and relative error (RE) remained below 6.10% and 12.55%, respectively. The limits of detection (LODs, S/N = 3) for all five analytes ranged from 2.0 to 56 ng/mL. Compared to the conventional capillary zone electrophoresis method, this new approach exhibited remarkable sensitivity enhancements, ranging from 123 to 235-fold. Upon applying this method to actual urine samples from patients, we successfully detected nordiazepam, zolpidem, and its metabolites. This simple and sensitive approach has promising applications in supporting patient medication safety and bolstering forensic investigations.

Abstract
Forensic investigations are often reliant on physical evidence to reconstruct events surrounding a crime. However, there remains a need for more objective approaches to evidential interpretation, along with rigorously validated procedures for handling, storage and analysis. Chemometrics has been recognised as a powerful tool within forensic science for interpretation and optimisation of analytical procedures. However, careful consideration must be given to factors such as sampling, validation and underpinning study design. This tutorial review aims to provide an accessible overview of chemometric methods within the context of forensic science. The review begins with an overview of selected chemometric techniques, followed by a broad review of studies demonstrating the utility of chemometrics across various forensic disciplines. The tutorial review ends with the discussion of the challenges and emerging trends in this rapidly growing field.

Abstract
Codeine is derived from morphine, an opioid analgesic, and has weaker analgesic and sedative effects than the parent molecule. This weak opioid is commonly used in combination with other drugs for over-the-counter cough relief medication. Due to the psychoactive properties of opioid drugs, the easily obtained codeine often becomes subject to misuse. Codeine misuse has emerged as a concerning public health issue due to its associated adverse effects such as headache, nausea, vomiting, and hemorrhage. Thus, it is very important to develop reliable analytical techniques to detect codeine for both quality control of pharmaceutical formulations and identifying drug misuse in the community. This review aims to provide critical outlooks on analytical methods applicable to the determination of codeine.

Abstract
A method for the fast isolation, propagation, and characterization of very low count bacteriophages active against pathogenic bacterial strains is described in this study. Bacteriophages with a count of 102 phage particles were dynamically adhered from the maximum 10 mL blood plasma sample onto the nanostructured part of the fused silica capillary. One-step propagation of phage particles of genus Kayvirus inside the etched capillary on 104 Staphylococcus aureus host cells increased their number to 6 × 104 phage particles. Phage particles were concentrated online and separated by capillary electrophoretic methods. No phage replication occurred when the phage-resistant S. aureus or Escherichia coli cells were used. Two-step phage propagation in the capillary allowed an increase in the total virion count to up to 6 × 105 phage particles and subsequent off-line matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis of the phage zone collected after capillary electrophoresis. Relative standard deviations of the phage peak area were at most 2.3%. We expect that the method of isolating bacteriophages from blood plasma and their simultaneous identification will facilitate clinical studies of phage preparations and contribute to pharmacokinetics studies during phage therapy. This approach is also suitable for capturing and enriching new phages from the environment when a susceptible indicator strain is available.

Abstract
Background:
Today, “drugs of abuse” pose serious social problems such as many crimes,
medical treatment costs, and economic repercussions. Several worldwide clinical laboratories use analytical
separation methods to analyze their patient samples for drugs and poisons. In this way, they
provide qualitative and quantitative data on the substances in various biological matrices (e.g., urine,
plasma or serum, saliva, and breath).
Methods:
An extensive review of the published articles indicates that the use of Capillary Electrophoresis
(CE) coupled with sensitivity enhancing methods is a very attractive area of interest in the
assay of drugs of abuse.
Results:
This review was prepared to have a comprehensive study on applications of sensitivity enhancing
methods on the determination of drugs of abuse especially from 2007 to present. The sample
preconcentration approaches almost address all methods from online preconcentration (both electrophoretic
and chromatographic-based methods) to offline preconcentration. Furthermore, detection
system modification and capillary column fabrications were investigated in order to increase the detection
sensitivity of complex samples in CE.
Conclusion:
The present review summarizes the most recent developments in the detection of drugs
of abuse using CE. Although CE still has a limitation in sensitive detection, several publications in
recent years have proposed valuable methods to overcome this problem.

Abstract
RATIONALE Drug abuse or dependence results in a series of social problems, including crime and traffic accidents. Spray-inlet microwave plasma torch tandem mass spectrometry (MPT-MS/MS) was developed and used for the direct detection of such drugs in liquid solutions. METHODS Drug sample solutions were directly sprayed into the flame of an MPT by a sampling pump and the ions produced by Penning ionization and ion-molecule reactions were guided into a quadrupole time-of-flight (QTOF) tandem mass spectrometer for mass analysis. The MPT was operated at 40 W and 2.45 GHz in a 700 mL/min argon flow both for the inner and middle plasma. RESULTS Intact quasi-molecular and molecular ions of various drugs were successfully characterized by spray-inlet MPT-MS/MS. The analysis of one sample was finished within 30 s. Furthermore, the method exhibited excellent efficiency, precision and sensitivity, and the limits of detection and limits of quantification of the samples in methanol were in the range of 5.25-60.0 and 17.5-200 ng g-1 , respectively. Excellent linearities with coefficients of determination (R2 ) of 0.9627-0.9980 were verified in the range 0.05-50 μg g-1 . Four different beverages purchased locally were also analyzed with spray-inlet MPT-MS/MS, and caffeine was directly determined in two of the beverages. By adding six standard drug samples to sport drinks (each drug was 1 μg g-1 ) and Chinese spirit (each drug was 0.1 μg g-1 ), all the drugs except for caffeine were detected successfully. CONCLUSIONS This study indicates that spay-inlet MPT-MS/MS is an effective method for direct and rapid identification of drug solutions, and it has substantial potential for fast and sensitive drug residue detection.

Abstract
Ketamine is an ionotropic glutamatergic N-methyl-D-aspartate receptor antagonist, which is widely used among recreational drug abusers. Ketamine abusers exhibit substantially reduced bladder capacity, which can lead to urinary frequency. The molecular pathogenesis of ketamine-induced cystitis has been scarcely reported. Given previous clinical findings, it may be hypothesized that pathological alterations in smooth muscle cells (SMCs) of the urinary bladder serve a crucial role in the mechanism underlying cystitis. In the present study, two lineages of SMCs, one from differentiated foreskin-derived fibroblast-like stromal cells and the other from cultured normal aortic SMCs, were used to study ketamine-induced molecular alterations. Polymerase chain reaction was used to study the effects of ketamine on oxidative stress. The effects of adjuvant chemo-therapy with cyclophosphamide (CTX) were also investigated. The results indicated that the expression levels of interleukin-6 and inducible nitric oxide synthase (iNOS) were decreased, whereas collagen expression and deposition were increased in ketamine-treated SMCs. Conversely, treatment with CTX restored the expression of iNOS, which may prevent or limit oxidative damage. In conclusion, the present study demonstrated that ketamine may induce several molecular alterations in SMCs and these changes may be associated with the clinical symptoms observed in ketamine abusers. In addition, the specific chemotherapeutic agent CTX may reverse these ketamine-induced aberrations.

Abstract
In this review we introduce the advantages and limitations of electromigrative separation techniques in forensic toxicology. We thus present a summary of illustrative studies and our own experience in the field together with established methods from the German Federal Criminal Police Office rather than a complete survey. We focus on the analytical aspects of analytes' physicochemical characteristics (e.g. polarity, stereoisomers) and analytical challenges including matrix tolerance, separation from compounds present in large excess, sample volumes, and orthogonality. For these aspects we want to reveal the specific advantages over more traditional methods. Both detailed studies and profiling and screening studies are taken into account. Care was taken to nearly exclusively document well-validated methods outstanding for the analytical challenge discussed. Special attention was paid to aspects exclusive to electromigrative separation techniques, including the use of the mobility axis, the potential for on-site instrumentation, and the capillary format for immunoassays. The review concludes with an introductory guide to method development for different separation modes, presenting typical buffer systems as starting points for different analyte classes. The objective of this review is to provide an orientation for users in separation science considering using capillary electrophoresis in their laboratory in the future.
