Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Moisture susceptibility of waste ceramic tiles modified asphalt mixtures

open access: yesResearch on Engineering Structures and Materials, 2023
Waste ceramic tiles have been recognized as viable in producing asphalt mixtures. However, the primary concern is the assurance of its durability, especially in terms of moisture damage. Therefore, this research aims to investigate the moisture susceptibility of asphalt mixtures incorporating waste ceramic tiles (WCT).

Characterization of Clinical Phenotype to Glial Fibrillary Acidic Protein Concentrations in Alexander Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine the concentration of glial fibrillary acidic protein (GFAP) in cerebrospinal fluid (CSF) and plasma in Alexander disease (AxD) and whether GFAP levels are predictive of disease phenotypes. Methods CSF and plasma were collected (longitudinally when available) from AxD participants and non‐AxD controls.
