Tris buffer-accelerated ligand exchange rate for instant fluorescence detection of trivalent chromium ion
In this study, we report that the good's buffers containing amino and polyhydroxy groups greatly increase the ligand exchange rate of Cr3+. Using EDTA as a model coordinate ligand, the Tris buffer (100 mM, pH 7.0) showed the best acceleration effect among the eight buffers. It improved the rate constant ∼20-fold, shorten the half-time 19-fold, and lowered the activation energy ∼70% at 40 °C. The Tris buffer was then applied for sensor based on the Cr3+-binding induced fluorescence quenching of fluorescein (FAM)-labeled and single-stranded DNA (ssDNA), which shortened the assay time from 1 h to 1 min. The Tris buffer a...

Toxicological profile and potential health concerns through metals and trace elements exposure in brick kiln workers from Lahore, Pakistan
This study examined levels of lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), and arsenic (As) in blood, hair, and nails of 18 brick kiln workers from three brick kiln units located around a metropolitan city, Lahore, Pakistan. All the trace elements except Hg and As were detected in the studied matrices of Brick kiln workers. In general, brick kiln workers reflect the highest concentration of Pb, followed by Cd, Cr, and Cu. Of the pollutants analyzed, Pb has the highest mean (min –max) concentrations at 0.35 (0.09–0.65) in blood (μg/mL), 0.34 (0.14–0.71) in hairs (μg/g), and 0.44 (0.32–0.59)...

Moss biomonitoring of air quality linked with trace metals pollution around a metallurgical complex in Elbasan, Albania
AbstractAnthropogenic pollution impacts human and environmental health, climate change, and air quality. Elbasan, an industrial town about 50 km from the capital city of Tirana, is susceptible to environmental contamination as a result of the outdated technology applied in metal processing and metallurgy. Environmental biomonitoring was conducted to provide a comprehensive view of contamination levels in atmospheric deposition as a resu lt of anthropogenic influences. The aim of this study is to evaluate the distribution of toxic metals in the atmospheric deposits in this area. Concentrations of thirteen trace metals wer...

Molecular mechanism analyses of post-traumatic epilepsy and hereditary epilepsy based on 10 × single-cell transcriptome sequencing technology
CONCLUSION: Our study explored differences in cells found in a patient with PE compared to a patient with HE, and the transcriptome in the different cells was analyzed for the first time. Studying inflammatory and immune functions might be the best approach for investigating traumatic temporal lobe epilepsy in neurons.PMID:38572804 | DOI:10.1111/cns.14702 (Source: CNS Neuroscience and Therapeutics)
