Anal Sci. 2024 Jan 23. doi: 10.1007/s44211-023-00487-2. Online ahead of print.ABSTRACTUnderstanding the redox reactions and transformation rates of mercury (Hg) species in the environment is important for predicting future gaseous elemental Hg (Hg0) levels and assessing the impacts of anthropogenic Hg0 emissions on human health. Stable Hg isotope tracers are a promising tool for estimating Hg0 production rates; however, traditional analytical approaches for quantifying Hg0, such as atomic fluorescence spectroscopy or atomic absorption spectrometry, cannot differentiate between Hg isotopes, and alternative approaches, such ...

Bowel perforation and anal ventriculoperitoneal shunt migration: A systematic review
CONCLUSIONS: Bowel and anal shunt migration is a relatively rare complication occurring predominantly within the initial weeks after the initial surgery. This condition leads to infectious complications, which can potentially be life-threatening. Urgent management is required, and in most cases, the removal of the shunt through the anus is sufficient. Early intervention generally results in favorable outcomes.PMID:38234714 | PMC:PMC10792256 | DOI:10.1016/j.jtumed.2023.12.002 (Source: Anal Sci)

Determination of phosphate in food based on molybdenum yellow derivatization coupled with resonance Rayleigh scattering method
Anal Sci. 2024 Jan 18. doi: 10.1007/s44211-023-00477-4. Online ahead of print.ABSTRACTThis paper proposed a rapid, selective and sensitive molybdenum yellow derivatization coupled with Resonance Rayleigh scattering (MYD-RRS) method for detection of phosphate. Under the acidic condition, phosphate can be selectively transformed to Keggin type of phosphomolybdic acid (PMA, i.e., PMo12O403-) through molybdenum yellow derivatization reaction prior to RRS detection. The PMA can further react with cationic methyl violet (MV) to form larger PMA-MV ion association complexes, generating significant RRS signal. The concentration of ...

UV-Vis spectrophotometry for rapid and specific quantification of amphotericin B: analytical method validation for ex vivo and in vivo studies in the development of nanoemulsion-incorporated thermosensitive gel
Anal Sci. 2024 Jan 18. doi: 10.1007/s44211-023-00493-4. Online ahead of print.ABSTRACTAmphotericin B (AmB) is the first-line drug used for the treatment of cryptococcal meningitis (CM). AmB has poor gastrointestinal permeability due to its large molecular weight. In addition, AmB in injectable form has the disadvantages of high systemic side effects and low bioavailability in the brain because it cannot cross the blood-brain barrier (BBB). Therefore, it is important to develop new drugs with a more optimized delivery system. The nose-to-brain drug delivery system offers many advantages such as high bioavailability in the b...

Anal Sci. 2024 Jan 16. doi: 10.1007/s44211-023-00485-4. Online ahead of print.ABSTRACTProcalcitonin (PCT) is a reliable biomarker in the early diagnosis of septicemia, pyemia and stroke-associated pneumonia. In this work, through preparing β-cyclodextrin/graphene (CD/GN) nanohybrid as carrier and amplifier simultaneously to band antibodies and probe molecules, a simple and innovative sandwich-like voltammetric immunosensor was proposed for the sensitive and effective determination of PCT. Owing to the host-guest recognition property, the antibodies of PCT can enter into the CD cavities to generate a stable complex; meanwh...

Rapid determination of chromium species in environmental waters using a diol-bonded polymer-stationary column under water-rich conditions coupled with ICPMS
This study proposes a rapid analytical approach for the simultaneous determination of Cr(VI) and Cr(III) in environmental waters by hydrophilic interaction chromatography (HILIC) coupled with ICPMS under a water-rich condition. 2,6-Pyridinedicarboxylic acid (PDCA) was used to unify Cr(III) species in various chemical forms into a stable Cr(III)-PDCA anion complex and then separated from Cr(VI) oxyanion on a diol-bonded polymer-based HILIC column. An aqueous mobile phase containing 50 mmol L-1 ammonium acetate (pH 7.0), 2 mmol L-1 PDCA, and 4% acetonitrile successfully separates chromium species as well as chloride ions. In...

Design of synthetic peptide-based fluorescence probes for turn-on detection of hyaluronan
Anal Sci. 2024 Jan 12. doi: 10.1007/s44211-023-00491-6. Online ahead of print.ABSTRACTHerein, we designed and examined a series of fluorescent peptide-based probes for turn-on detection of hyaluronan (HA), a member of the glycosaminoglycan family. We utilized two kinds of synthetic HA-binding peptides as the binding unit for HA, and each peptide was coupled with three kinds of environment-sensitive fluorophores as the signaling unit. From the examination of the peptides, fluorophores, and the position and number of fluorophore modification, we found that X7 peptide (RYPISRPRKR) labelled with an aggregation-induced emission...
