The Industrial Application Potential of Sugar Beet Pulp Derived Monosaccharides d-Galacturonic Acid and l-Arabinose

This review provides a perspective on the industrial application potential of sugar beet pulp (SBP) derived monosaccharides. The broad application of these monosaccharides could contribute to bio-based alternatives and sustainable practices, essential for the transition towards a more circular economy. This review focuses on the utilization and application of two SBP monosaccharides, d-galacturonic acid (d-GalA) and l-arabinose (l-Ara), derived from pectin and hemicellulose. These polysaccharides are major components of sugar beet pulp, an important side stream of sucrose production. d-GalA and l-Ara are therefore abundant in biomass and offer unique molecular structures amenable to selective chemical or enzymatic modifications. We review their application in various industrial applications such as the development and production of bioactive compounds, home and personal care products, and other industries.

Lipophilic Polyamines as Promising Components of Liposomal Gene Delivery Systems

Gene therapy requires an effective and safe delivery vehicle for nucleic acids. In the case of non-viral vehicles, including cationic liposomes, the structure of compounds composing them determines the efficiency a lot. Currently, cationic amphiphiles are the most frequently used compounds in liposomal formulations. In their structure, which is a combination of hydrophobic and cationic domains and includes spacer groups, each component contributes to the resulting delivery efficiency. This review focuses on polycationic and disulfide amphiphiles as prospective cationic amphiphiles for gene therapy and includes a discussion of the mutual influence of structural components.

Efficient Modulation of β-Amyloid Peptide Fibrillation with Polymer Nanoparticles Revealed by Super-Resolution Optical Microscopy

β-Amyloid peptide (Aβ) aggregation is the essential hallmark of neurodegenerative disorders such as Alzheimer's disease. Efficient inhibitors are highly desired for the prevention of Aβ assembly that has been considered as the primary therapeutic strategy for neurodegenerative diseases. Apart from this, visualization of the aggregates and morphology at high spatial resolution is widely considered of crucial significance on biological treatment. In this work, we have developed small-sized (with diameter of ∼4.7 nm) and positively charged fluorescent conjugated polymer nanoparticles (CPNPs) with strong inhibition effect on Aβ_1-40 peptides fibrillation. Interestingly, the CPNPs also possess excellent photophysical properties, including high photon counts, robust blinking, and repetitive fluorescence switching, that are especially suitable for localization-based super-resolution imaging. Spatial resolution of ∼20 nm for these blinking CPNPs is readily achieved. According to the optical microscopic results, it was found that binding of CPNPs to the terminal of seed fibrils can effectively inhibit the fibrillation process. Owing to these attractive biological and unique photophysical properties, the small-sized CPNPs show high potential in a variety of super-resolution based biological applications.
