After enjoying curry: urine metabolism analysis of curcuminoids by microemulsion electrokinetic chromatography with laser-induced native fluorescence detection. J Chromatogr A 2020; 1635:461729. [PMID: 33250162 DOI: 10.1016/j.chroma.2020.461729] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 11/14/2020] [Accepted: 11/16/2020] [Indexed: 12/15/2022]
Abstract
Considering pH-dependent fluorescence of curcuminoids, a microemulsion electrokinetic chromatographic (MEEKC) method was developed under acidic conditions for their separation and detection using laser-induced native fluorescence (LINF), so as to solve the analysis of urine metabolism for curcuminoids. The microemulsion composition was optimized by response surface methodology (RSM), and the effects of buffer pH and organic modifiers were systematically investigated. The optimal buffer for the separation of curcuminoids was chosen as follows: 2.8% (v/v) ethyl acetate, 80 mM SDS and 2.8% (v/v) n-butanol to form microemulsion, 28% (v/v) ethanol as organic modifier, and 20 mM phosphoric acid as electrolyte at pH 3.0. Under these conditions, four curcuminoids including curcumin, demethoxy curcumin (DMC), bisdemethoxy curcumin (BDMC) and demethyl curcumin (DEC) could be well separated within 18 min, and the detection limits (LOD, based on S/N=3) were calculated to be 71, 60, 22, and 147 pg mL-1, respectively. Combined with solid-phase extraction (SPE), the developed MEEKC-LINF method has been successfully applied to continuously monitor the curcuminoids and related metabolites in human urine collected from a healthy volunteer after oral administration of curry, testifying that this method has potential for evaluating the pharmacological activity of curcuminoids.

Abstract
Recently, it has been crucial to be able to detect and quantify small molecular targets simultaneously in biological samples. Herein, a simple and conventional double-T type microchip electrophoresis (MCE) based platform for the multiplex detection of quality indicator molecule targets in urine, using ampicillin (AMPI), adenosine triphosphate (ATP) and estradiol (E2) as models, was developed. Several programmable hairpin probes (PHPs) were designed for detecting different targets and triggering isothermal polymerase-catalyzed target recycling (IPCTR) for signal amplification. Based on the target-responsive aptamer structure of PHP (Domain I), target recognition can induce PHP conformational transition and produce extension duplex DNA (dsDNA), assisted by primers & Bst polymerase. Afterwards, the target can be displaced to react with another PHP and initiate the next cycle. After several rounds of reaction, the dsDNA can be produced in large amounts by IPCTR. Three targets can be simultaneously converted to dsDNA fragments with different lengths, which can be separated and detected using MCE. Thus, a simple double-T type MCE based platform was successfully built for the homogeneous detection of multiplex targets in one channel. Under optimal conditions, the assay exhibited high throughput (48 samples per hour at most, not including reaction time) and sensitivity to three targets in urine with a detection limit of 1 nM (ATP), 0.05 nM (AMPI) and 0.1 nM (E2) respectively. The multiplex assay was successfully employed for the above three targets in several urine samples and combined the advantages of the high specificity of programmable hairpin probes, the excellent signal amplification of IPCTR, and the high through-put of MCE which can be employed for screening in biochemical analysis.

Microfluidic electrophoretic non-enzymatic kanamycin assay making use of a stirring bar functionalized with gold-labeled aptamer, of a fluorescent DNA probe, and of signal amplification via hybridization chain reaction.

Abstract
The authors describe an enzyme-free aptamer-based assay for the determination of the model antibiotic kanamycin (Kana). The method is making use of (a) microfluidic chip electrophoresis; (b) a stirring bar carrying a gold-labeled aptamer probe, and (c) the hybridization chain reaction (HCR) for signal amplification. Firstly, a stirring bar (length: 1 cm; diameter: 0.2 mm) was modified with a large amount of duplex DNA and then hybridized with aptamer and its partially complementary chains (cDNA). In the presence of Kana, the binding between the Kana and aptamer unwinds the duplex structures and releases a corresponding amount of cDNA into the supernatant. The released cDNA triggers the HCR in the presence of H1 and H2 DNA hairpin to produce a large amount of duplex DNA chains with different lengths. At the same time, the amounts of H1 and H2 are reduced. The decreased signal of H1/H2 after several HCR cycles can be used to quantify kana in the 1 pg·mL-1 to 10 ng·mL-1, with a detection limit of 0.29 pg·mL-1. The signal is generated by reading the fluorescence, best at excitation/emission maxima of 470/525 nm. The whole detection process takes 3 min only. The assay was employed to the detection of Kana in spiked milk and fish samples. Results are consistent with those of an enzyme linked immunosorbent assay. The assay has high throughput, high selectivity, and high amplification capability. Graphical abstract Schematic of a stirring bar functionalized with gold-labeled aptamer acting as the capture probe. It can capture the target and release primer simultaneously. The primer triggers the hybridization chain reaction inducing the consumption of H1 and H2. After a certain reaction time, the mixture is injected into the MCE platform for microfluidic electrophoretic separation and fluorometric detection.

Abstract
The ability to use microchip-based electrophoresis for fast, high-throughput separations provides researchers with a tool for close-to real time analysis of biological systems. While PDMS-based electrophoresis devices are popular, the separation efficiency is often an issue due to the hydrophobic nature of PDMS. In this study, a hybrid microfluidic capillary device was fabricated to utilize the positive features of PDMS along with the electrophoretic performance of fused silica. A capillary loop was embedded in a polystyrene base that can be coupled with PDMS microchannels at minimal dead volume interconnects. A method for cleaning out the capillaries after a wet-polishing step was devised through the use of 3D printed syringe attachment. By comparing the separation efficiency of fluorescein and CBI-glycine with both a PDMS-based serpentine device and the embedded capillary loop device, it was shown that the embedded capillary loop device maintained higher theoretical plates for both analytes. A Pd decoupler with a carbon or Pt detection electrode were embedded along with the loop allowing integration of the electrophoretic separation with electrochemical detection. A series of catecholamines were separated to show the ability to resolve similar analytes and detect redox active species. The release of dopamine and norepinephrine from PC 12 cells was also analyzed showing the compatibility of these improved microchip separations with high ionic cell buffers associated with cell culture.

Abstract
Rapid transmission, high morbidity, and mortality are the features of human infectious diseases caused by microorganisms, such as bacteria, fungi, and viruses. These diseases may lead within a short period of time to great personal and property losses, especially in regions where sanitation is poor. Thus, rapid diagnoses are vital for the prevention and therapeutic intervention of human infectious diseases. Several conventional methods are often used to diagnose infectious diseases, e.g. methods based on cultures or morphology, or biochemical tests based on metabonomics. Although traditional methods are considered gold standards and are used most frequently, they are laborious, time consuming, and tedious and cannot meet the demand for rapid diagnoses. Disease diagnosis using capillary electrophoresis methods has the advantages of high efficiency, high throughput, and high speed, and coupled with the different nucleic acid detection strategies overcomes the drawbacks of traditional identification methods, precluding many types of false positive and negative results. Therefore, this review focuses on the application of capillary electrophoresis based on nucleic detection to the diagnosis of human infectious diseases, and offers an introduction to the limitations, advantages, and future developments of this approach.

Abstract
An automated capillary DNA sequencer with laser-induced fluorescence detection can be utilised for DNA fragment analysis. The precise mobilities of DNA fragments with different chemical termini are especially important in the determination of the sequence specificity of DNA damaging agents. The aim of this study was to examine the electrophoretic mobility profile of DNA fragments with different 3'-termini. The nature of the 3'-teminal residue was found to have a major effect on the electrophoretic mobility of the DNA fragment, especially for 3'-phosphoglycolate termini that migrated anomalously by 3-6 nucleotides. Using the automated capillary sequencer, the electrophoretic mobilities of DNA fragments with different 3'-termini including 3'-hydrogen, 3'-hydroxyl, 3'-phosphate, and 3'-phosphoglycolate were extensively quantified and compared relative to each other. The 3'-hydrogen termini were generated by dideoxy sequencing; 3'-hydroxyl ends by minus sequencing; 3'-phosphate by Maxam-Gilbert chemical sequencing; and 3'-phosphoglycolate by bleomycin cleavage. The mobilities of these DNA fragments with different 3'-termini were found to be: (slowest) 3'-hydroxyl<3'-hydrogen<3'-phosphate<3'-phosphoglycolate (fastest); with average relative mobilities of 0.00<0.12<0.63<4.42 nucleotides, respectively. The possible causes of the unusual electrophoretic mobility of the 3'-phosphoglycolate termini were discussed.
