Metabolic Hydrogen Flows in Rumen Fermentation: Principles and Possibilities of Interventions [PDF]
Frontiers in Microbiology, 2020 Rumen fermentation affects ruminants productivity and the environmental impact of ruminant production. The release to the atmosphere of methane produced in the rumen is a loss of energy and a cause of climate change, and the profile of volatile fatty ...

Differential metabolic responses to hydrogen peroxide-induced oxidative stress in parotid and submandibular gland acinar cell lines [PDF]
Biochemistry and Biophysics ReportsThis study explored how oxidative stress induced by hydrogen peroxide alters metabolite levels in submandibular and parotid salivary gland acinar cells. We investigated the impact of oxidative stress on the metabolite profiles of two salivary gland cell ...

Inhibiting Methanogenesis in Rumen Batch Cultures Did Not Increase the Recovery of Metabolic Hydrogen in Microbial Amino Acids [PDF]
Microorganisms, 2019 There is an interest in controlling rumen methanogenesis as an opportunity to both decrease the emissions of greenhouse gases and improve the energy efficiency of rumen fermentation. However, the effects of inhibiting rumen methanogenesis on fermentation

Metabolic turnover of hydrogen sulfide [PDF]
Frontiers in Physiology, 2012 More than 15 years have passed since hydrogen sulfide (H2S) emerged as a biological signaling molecule – initially, in the nervous and vascular systems through the modulation of N-methyl d-aspartate (NMDA) receptors and the activation of transmembrane receptor potential (TRP)- and ATP-dependent K+ (KATP)-channels (Abe and Kimura, 1996; Hosoki et al ...

Enzyme-constrained genome-scale modeling resolves growth-production trade-offs in fermentative biohydrogen production [PDF]
Environmental Science and EcotechnologyHydrogen is central to sustainable energy systems, with biological production from waste offering a low-energy, environmentally compatible route. Anaerobic dark fermentation by microbes converts organic substrates into hydrogen, yet yields remain limited

Hydrogen gas with hypothermic machine perfusion induces lipidomic alterations in donation-after-cardiac-death rat livers [PDF]
Journal of Lipid ResearchHypothermic machine perfusion (HMP) combined with hydrogen gas has previously been shown to mitigate ischemia-reperfusion injury (IRI) in rat liver, but without full recovery of function.
