conversion of crude glycerol from the biodiesel industry to value added products
(2017)crude glycerol is a major by-product of the biodiesel industries. for every 100 kg of biodiesel produced, approximately 10 kg of the byproduct glycerol is generated. with the large increase in biodiesel production, there ... -
hydrogen sulfide modulates gluconeogenesis and mitochondrial biogenesis in mouse primary hepatocytes
(2016)among many endogenous substances that regulate hepatic energy production is the gasotransmitter hydrogen sulfide (h2s). in the liver, h2s production is largely catalyzed by cystathionine γ-lyase (cse) and, to a lesser ... -
modelling the molecular mechanisms of biocompatibility of artifical materials
(2015)one of the most common reasons for implant failure is immune rejection. implant rejection leads to additional surgical intervention and, ultimately, increases health cost as well as recovery time. within a few hours after ... -
