Elucidation of Non-Intentionally Added Substances from Plant Fiber/Plastic Composites by UPLC-QTOF/MS

open access: yesFoods, 2023
Plant fiber/plastic composites (PPCs) have been widely used in food contact materials (FCMs) for many benefits, such as their claimed better environmental footprint compared to conventional plastics.

Migration Modeling as a Valuable Tool for Exposure Assessment and Risk Characterization of Polyethylene Terephthalate Oligomers

open access: yesMolecules, 2022
Polyethylene terephthalate (PET) is one of the most widely used food contact materials due to its excellent mechanical properties and recyclability. Migration of substances from PET and assessment of compliance are usually determined by experimental ...

A Targetable N-Terminal Motif Orchestrates α-Synuclein Oligomer-to-Fibril Conversion

open access: yesbioRxiv
Oligomeric species populated during α-synuclein aggregation are considered key drivers of neurodegeneration in Parkinson’s disease. However, the development of oligomer-targeting therapeutics is constrained by our limited knowledge of their structure and

Regulation of small heat-shock proteins by hetero-oligomer formation

open access: yesJournal of Biological Chemistry, 2019
Small heat-shock proteins (sHsps) compose the most widespread family of molecular chaperones. The human genome encodes 10 different sHsps (HspB1–10). It has been shown that HspB1 (Hsp27), HspB5 (αB-crystallin), and HspB6 (Hsp20) can form hetero-oligomers

A hyperbranched P/N/B-containing oligomer as multifunctional flame retardant for epoxy resins

open access: yes, 2022
Flame-retardant epoxy resins (EPs) with superior optical, mechanical and dielectric properties are highly desired in high-tech industries. In this work, a multifunctional hyperbranched additive (BDHDP) was synthesized for EPs.

Understanding the Pathophysiological Actions of Tau Oligomers: A Critical Review of Current Electrophysiological Approaches

open access: yesFrontiers in Molecular Neuroscience, 2020
Tau is a predominantly neuronal protein that is normally bound to microtubules, where it acts to modulate neuronal and axonal stability. In humans, pathological forms of tau are implicated in a range of diseases that are collectively known as tauopathies.

Different Amyloid-β Self-Assemblies Have Distinct Effects on Intracellular Tau Aggregation

open access: yesFrontiers in Molecular Neuroscience, 2019
Alzheimer’s disease (AD) pathology is characterized by the aggregation of beta-amyloid (Aβ) and tau in the form of amyloid plaques and neurofibrillary tangles in the brain.

Architecture of the native major royal jelly protein 1 oligomer

open access: yesNature Communications, 2018
Honeybee caste development is nutritionally regulated by royal jelly (RJ). Major royal jelly protein 1 (MRJP1), the most abundant glycoprotein among soluble royal jelly proteins, plays pivotal roles in honeybee nutrition and larvae development, and ...

Characterization of Proanthocyanidin Oligomers of Ephedra sinica

open access: yesMolecules, 2017
Ephedra sinica, an important plant in Chinese traditional medicine, contains a complex mixture of proanthocyanidin oligomers as major constituents; however, only the minor components have been chemically characterized.
