Use of Batroxobin in Central and Peripheral Ischemic Vascular Diseases: A Systematic Review

open access: yesFrontiers in Neurology, 2021
Background and Purpose: The mechanism of action of Batroxobin included the decomposition of the fibrinogen to fibrin degradation products (FDPs) and D-dimer and mobilization of endothelial cells to release endogenous nt-PA and to promote thrombolysis ...

Catalytic oxidation of lignin in solvent systems for production of renewable chemicals: A review [PDF]

open access: yes, 2017
Lignin as the most abundant source of aromatic chemicals in nature has attracted a great deal of attention in both academia and industry. Solvolysis is one of the promising methods to convert lignin to a number of petroleum-based aromatic chemicals.

Base-catalyzed oxidative depolymerization of softwood kraft lignin

open access: yesIndustrial Crops and Products, 2020
Abstract Lignin is an important aromatic biopolymer with the structure based on phenolic units. Depolymerized lignin materials can be useful substitutes for phenol in phenol-formaldehyde resins. Our aim was to examine the potential of the base-catalyzed oxidation method to provide reactive oligomeric lignin fragments from softwood kraft lignin ...

Depolymerization Pathways for Branching Lignin Spirodienone Units Revealed with ab Initio Steered Molecular Dynamics [PDF]

open access: yes, 2016
Lignocellulosic biomass is an abundant, rich source of aromatic compounds, but direct utilization of raw lignin has been hampered by both the high heterogeneity and variability of linking bonds in this biopolymer.
