Visible-light-mediated photoredox reactions have recently emerged as a powerful means for organic synthesis and thus generated significant interest from the chemistry community. Although mechanisms of these been probed by number techniques such NMR, fluorescence quenching, laser flash photolysis various degrees success has achieved, mechanistic ambiguity still exists (for instance, involvement chain mechanism is under debate) because lack structural information about proposed short-lived...
In single-cell analysis with ICP-MS it is highly important to ensure precise sampling into ICP. For this purpose, a simple configured pressure-resistant MicroCross interface developed for high-throughput/high-precision microdroplet generation and encapsulation. Aqueous cell suspension ejected sheared droplets by tangent-flowing hexanol-continuous phases in the flow-focusing geometry of MicroCross, wherein precisely trap single droplet, an extremely low probability <0.005% droplet...
The scope of dielectric barrier discharge (DBD) microplasma as a radiation source for optical emission spectrometry (OES) is extended by nickel carbonyl vapor generation. We proved that metal completely avoids the extinguishing plasma, and it much more suitable matching DBD excitation OES detection with respect to significant quenching concomitant hydrogen when hydride generation used. A concentric quartz UV reactor allows sample solution flow through central channel wherein efficiently...
Microplasma optical-emission spectrometry (OES) is a promising technique for developing portable analytical instrumentations real-time and on-site measurement of trace elemental species. However, its performance far from satisfactory multielement analysis. Herein, miniature OES system developed simultaneous analysis with alternating-current-driven microplasma generated on the nozzle pneumatic micronebulizer as excitation source. Because strong capability sufficient contact solution, series...
The transporter protein ABC subfamily G member 2 (ABCG2) is implicated in epilepsy; however, its specific role remains unclear. In this study, we assessed changes ABCG2 expression and epilepsy both vitro vivo. We observed an instantaneous increase epileptic animals cells. Further, overexpression significantly suppressed the oxidative stress apoptosis induced by glutamate, kainic acid (KA), lipopolysaccharide (LPS) neuronal microglia Furthermore, inhibiting activity offset protective effect....
High-resolution mass spectra of single submicrometer-sized particles are obtained using an electrospray ionization source in combination with audio frequency quadrupole ion-trap spectrometer. Distinct from conventional methods, light scattering a continuous Ar-ion laser is detected for ejected out the ion trap. Typically, 10 being trapped and interrogated each measurement. With trap operated mass-selective instability mode, analysis reveals that they all differ mass-to-charge ratio (m/z),...
Abstract In this study, we investigated a simple, sensitive and reliable liquid chromatography‐fluorescence detection method for the determination of memantine hydrochloride in rat plasma which was based on derivatization with 9‐fluorenylmethyl chloroformate (FMOC‐Cl). For first time, FMOC‐Cl introduced into plasma. The amino groups amantadine (internal standard) were trapped to form hydrochloride‐FMOC‐Cl compositions, can be very compatible LC‐FLD. Precipitation proteins by acetonitrile...
Abstract Objective Amphenicols (chloramphenicol, thiamphenicol and florfenicol) can cause aplastic anaemia other severe side effects to consumers; therefore, it is necessary inspect their residues in foods of animal origin. However, there has been no report on the use amphenicols receptor for determination residues, none previously reported immunoassays differentiate specific species. Materials Methods In this study, ribosomal protein L16 Escherichia coli was first expressed, its...
