The purpose of this research was to determine whether a quantitative H2S test could correctly identify fecally contaminated water samples and determine if there was any relationship between the test results and diarrheal disease risk. Using culture-based biochemical and culture-independent molecular ...

This paper presents field test results for a new two-point continuous hydrogen sulfide monitor (CEM) combining a versatile two-point sampling system with two independent H2S Gas Loggers: one for measuring 0 to 200 ppm; +/- 1 ppm, the other for measuring from 0 to 2 ppm; (+/- 5 ppb...
These results showed that the probe has a high selectivity for H2S over the other tested analytes, suggesting that probe had the potential to detect hydrogen sulfide in living biological systems. Figure 4 Fluorescence responses of Na-H 2 S-ER (5 μM) in the presence of various relevant ...
Here, we show that Desulfovibrio, an intestinal symbiont enriched in patients with MetS, suppresses the production of the gut hormone glucagon-like peptide 1 (GLP-1) through the production of hydrogen sulfide (H2S) in male mice. Desulfovibrio-derived H2S is found to inhibit mitochondrial ...
The portable Jerome® 631-X Hydrogen Sulfide Analyzer displays low-level concentrations in just seconds. It offers an analysis range of 0.003-50 ppm for odor and corrosion control, safety, and leak detection in such industries as wastewater treatment,
Results show significantly reduced sulfide metabolites with the exception of bound sulfane sulfur in COVID-19 patients (n = 68) compared to Controls (n = 33). 3.3. Race-based comparison of NO metabolites in COVID-19 patients The association of plasma NO levels were compared between COVID-19...

Results and Discussion Sulfide Inhibits Mitochondrial Respiration; Reversal by Cobinamide. Sodium hydrogen sulfide (NaSH) is used commonly as a sulfide source, because it is stable, and much easier to work with than hydrogen sulfide gas3–5,11,14. Using NaSH, we studied sulfide toxicity in...
