A new ratiometric fluorescent probe for rapid and highly selective detection of Cysteine in bovine serum
Anal Sci. 2024 Feb 15. doi: 10.1007/s44211-024-00516-8. Online ahead of print.ABSTRACTAs one of the most fundamental thiol compounds in the human body, cysteine (Cys) is involved in maintaining redox balance. Abnormal Cys levels can lead to various diseases. In this work, we successfully synthesized a fluorescent probe (CTBA) that can specifically detect Cys using acrylate as the reaction site, and CTBA has met the selectivity and anti-interference for Cys detection under optimized conditions. The linear range for Cys detection is between 0.05 and 100 μM and the detection limit is 0.0381 μM. Finally, this probe is used t...

Electrochemical determination of riboflavin in pharmaceuticals using unmodified screen printed carbon electrodes
In this study, we have devised an efficient and rapid approach to detect riboflavin (also known as Vitamin B2 or VB2) utilizing an unaltered screen-printed carbon electrode (SPCE). The unmodified screen-printed electrodes are created within the laboratory, where carbon ink is applied to a ceramic substrate. All experiments pertaining to the investigation of electrochemical behavior and the fine-tuning of crucial experimental parameters were conducted through cyclic voltammetry (CV). For quantitative assessments, square wave voltammetry (SWV) was employed. The findings indicate that unaltered SPCEs exhibit robust current si...

Role of Adipose Tissue Hormones in Pathogenesis of Cryptoglandular Anal Fistula
Int J Mol Sci. 2024 Jan 25;25(3):1501. doi: 10.3390/ijms25031501.ABSTRACTThe cryptoglandular perianal fistula is a common benign anorectal disorder that is managed mainly with surgery and in some cases may be an extremely challenging condition. Perianal fistulas are often characterized by significantly decreased patient quality of life. Lack of fully recognized pathogenesis of this disease makes it difficult to treat it properly. Recently, adipose tissue hormones have been proposed to play a role in the genesis of cryptoglandular anal fistulas. The expression of adipose tissue hormones and epithelial-to-mesenchymal transit...

Improvement of limit of detection in primer extension-based multiplexed mutation assay using capillary electrophoresis
Anal Sci. 2024 Feb 6. doi: 10.1007/s44211-024-00508-8. Online ahead of print.ABSTRACTOne of the challenges in liquid biopsy for early cancer detection is ascribed to the fact that mutation DNA often represents an extremely small ratio of less than 1% compared to wild-type genes in blood. However, in conventional fragment analysis with capillary electrophoresis (CE), the detectable allele frequency could be about 5%. In this work, we developed an original reagent-based fragment analysis with single base extension (SBE) reactions for cancer-associated mutation assay using a commercially available CE device, and investigated ...

A selective colorimetric chemosensor for detecting Ni(II) in aqueous solutions based on 4-[{[4-(3-chlorophenyl)-1,3-thiazol-2-yl]hydrazono}methyl]phenyl 4-methyl benzene sulfonate (CTHMBS)
In this study, a novel selective chemosensor (4-[{[4-(3-Chlorophenyl)-1,3-Thiazol-2-yl]Hydrazono}Methyl]phenyl4-methylBenzene Sulfonate (CTHMBS) was developed for the colorimetric detection of Ni(II) in aqueous medium. The presence of Ni(II) led to a distinct naked-eye color change from yellow to reddish-brown in aqueous solution. To examine the binding mechanism of CTHMBS to Ni(II), UV-vis spectroscopy analysis and DFT calculations were conducted. The detection limit of CTHMBS for Ni(II) was 11.87 µM, and the sensing ability of CTHMBS for Ni(II) was successfully carried out in real water samples.PMID:38308675 | DOI:10.10...

< em > In situ < /em > detection of silk fibroin using a dual recognition strategy with a flexible pressure immunosensor
Anal Methods. 2024 Feb 2. doi: 10.1039/d3ay01967e. Online ahead of print.ABSTRACTSilk is a symbol of ancient Chinese civilization that has made an indelible contribution to the development of world civilization. However, because ancient artifacts are often contaminated or degraded, it is difficult to detect the presence of silk therein, and the true origin of silk thus remains a mystery. Therefore, this work presents a flexible pressure immunosensor that was designed based on 3D polypyrrole (PPy) foams for the trace detection of silk fibroin at archaeological sites. Initially, silk fibroin (SF) was conjugated with antibody...
