An inexpensive paper-based sensor was developed for detecting low ppm concentrations of hydrogen sulfide gas. A piece of filter paper containing aquohydroxocobinamide [OH(H2O)Cbi] was placed on the end of a bifurcated optical fiber, and the reflectance spectrum of the OH(H2O)Cbi was monitored during exposure to 10.0 ppm hydrogen sulfide gas (NIOSH recommended exposure limit). Reaction of sulfid...
Homocysteine can be methylated to form methionine by the cobalamin- (Cbl) and folate-dependent enzyme, methionine synthase; serum levels of total homocysteine are elevated in greater than 95% of patients with either Cbl or folate deficiency. Homocysteine can also condense with serine to form cystathionine in a pyridoxal phosphate-dependent reaction catalyzed by cystathionine beta-synthase. Cyst...
Hydrogen sulfide (H2S) is known to act protectively during renal ischemia/reperfusion injury (IRI). However, the role of the endogenous H2S in acute kidney injury (AKI) is largely unclear. Here, we analyzed the role of cystathionine gamma-lyase (CTH) in acute renal IRI using CTH-deficient (Cth(-/-)) mice whose renal H2S levels were approximately 50% of control (wild-type) mice. Although levels ...

In acute experiments on laboratory rats, intra-portal administration of L-cysteine (20 mg/kg), the precursor hydrogen sulfide synthesis, stimulated oxygen consumption liver by 38.6% and reduced tension 37.1%. Activation tissue respiration occurred due to strengthening oxygen-dependent synthetic processes in liver, particular those associated with mitochondrial enzyme-catalysed bile acid biosynt...
