Thermodynamic analysis of liquid phase in situ hydrogenation of glycerol for 1,3-propanediol synthesis

Kun OUYANG, Yu HUANG, Haoyi CHEN, Tao LI, Fahai CAO, Dingye FANG

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 1,   Pages 67-73 doi: 10.1007/s11705-010-0541-6

Abstract: glycerol, a novel reaction system of liquid phase in situ hydrogenation of glycerol for the synthesis of 1,3-propanediolpropanediol is proposed, in which hydrogen is produced from glycerol aqueous-phase reforming in the samethe APR of glycerol can be quickly transformed to the in situ hydrogenation of glycerol to produce 1,3-propanediolpropanediol, which can improve the selectivity of hydrogen for the APR process of glycerol.The above calculation results indicate that the combination process is feasible for 1,3-propanediol synthesis

Adsorption of 1,3-propanediol from synthetic mixture using polymeric resin as adsorbents

W. LUERRUK, A. SHOTIPRUK, V. TANTAYAKOM, P. PRASITCHOKE, C. MUANGNAPOH

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 1,   Pages 52-57 doi: 10.1007/s11705-009-0087-7

Abstract: The aim of this work was to separate 1,3-PDO from a synthetic mixture using polymeric resins, Amberlite XAD-7 and XAD-16 resins. The equilibrium adsorption of 1,3-PDO onto two polymeric resins were investigated in binary and tertiary systems. Experimental results of binary component adsorption equilibrium indicated that the adsorption capacity ( ) of 1,3-PDO at 160 g/L onto XAD-7 and XAD-16 was 835.96 and 584.61 mg 1,3-PDO/g dry resin, respectively. The adsorption isotherms were closely predicted by the Langmuir-Freundlich model among the two isotherm model tested. The value of n of 1,3-PDO adsorbed on XAD-7 are much higher than those on XAD-16. This result suggested that XAD-7 resin has a higher affinity for the 1,3-PDO adsorption than XAD-16 resin. Moreover, the value of adsorption capacity of 1,3-PDO in the binary and tertiary component were compared at the same conditions. In the tertiary system, although the selectivity of 1,3-PDO from XAD-7 was approximately six times higher than XAD-16, the adsorption capacity of 1,3-PDO at 160 g/L onto XAD-16 was higher than XAD-7. Interestingly, the reusability of XAD-7 and XAD-16 resins in the three cycle times shows a slight loss of adsorption capacity. Furthermore, the investigation about desorption by an ethanol/water mixture at 50% ( / ) indicated that the desorption yield of 1,3-PDO from XAD-7 was lower than XAD-16 resin for both the binary and tertiary component. This was due to the more favorable adsorption characteristics of XAD-7 resin than XAD-16 resin.

FOXP3 and Its Cofactors as Targets of Immunotherapies Review

Engineering 2019, Volume 5, Issue 1,   Pages 115-121 doi: 10.1016/j.eng.2019.01.001

Abstract:

Forkhead box P3 (FOXP3) is a "master regulator" of regulatory T cells (Tregs), which areAs a consequence, the PTMs change the stability of FOXP3 and its capability to regulate gene expressionAlthough FOXP3 per se is not an ideal drug target, deacetylases, acetyltransferases, kinases, and other enzymes that regulate the PTMs of FOXP3 are potential targets to modulate FOXP3 and TregFOXP3" side effects must be considered when inhibitors to these enzymes are used.

Frontiers of Medicine doi: 10.1007/s11684-023-1003-0

Abstract: However, little is known about the function of Lipin3 in triglyceride (TG) metabolism.Hence, we generated Lipin3 heterozygous knockout (Lipin3-heKO) mice and cultured primary hepatocytesto explore the pathophysiological roles of Lipin3 in TG metabolism.Our study suggested that Lipin3 was a novel disease-causing gene inducing obesity and HTG.We also established a relationship between Lipin3 and mitochondrial dysfunction.
