The misfolding of proteins can lead to fibrillar and non-fibrillar deposits that are the hallmark of numerous human diseases. Inhibition of protein aggregation is considered as a promising strategy for the prevention of such diseases. Here we induced the fibrillar and non-fibrillar aggregates of hen egg white lysozyme (HEWL) at acidic (pH 3) and physiological (pH 7.4) environments. HEWL formed non-fibrillar aggregates rapidly at pH 7.4, whereas fibrillar HEWL aggregates were formed slowly at pH 3. Both fibrillar and non-fibrillar aggregates had cytotoxic effects on PC12 cells. Next, four organic acids, succinic acid, maleic acid, tartaric acid and citric acid, were tested for their inhibition potencies against fibrillar and non-fibrillar HEWL species. The four inhibitors were found to prevent the aggregation of HEWL at pH 7.4 with a reduction rate of over 95% as compared with the reduction rate of 42-58% for HEWL aggregation at pH 3. Other biophysical and computational analyses reveal that the candidate inhibitors have higher inhibition efficacy against HEWL monomers incubated at pH 7.4 than at pH 3. These results emphasize the importance of validating the newly identified aggregation drugs against different aggregate species, which would enhance the understanding of small molecules-induced protein aggregation inhibition. Amylosucrase (AS) catalyzes the transfer of a glucosyl unit from sucrose onto α-1,4-linked glucan polymers in starch. In this study, AS from Deinococcus geothermalis (DgAS) was applied to produce modified rice starches with slowly digestible properties. DgAS-treated waxy and normal rice starches showed significantly (p less then 0.05) elevated degrees of polymerization, suggesting that the external chains were elongated. Additionally, the crystalline structures of starches changed from A- to B-type, and the temperature transition properties of enzymatically modified rice starches increased. The amounts of slowly digestible starch (SDS) increased remarkably (20.1% and 18.8%; waxy and normal rice starches, respectively), and the DgAS-treated rice starches were slowly hydrolyzed to glucose at the mammalian mucosal α-glucosidase level. Thus, DgAS-treated rice starches can be used to produce SDS-based ingredients that attenuate the glucose spike after glycemic food ingestion. Magnetic graphene nanocomposites were prepared by hydrothermal synthesis, and aniline polymerization was initiated by magnetic graphene. These polyaniline/magnetic graphene (PANI/MG) composites were used to immobilize laccase to construct biosensors. Glucagon Receptor agonist Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and infrared spectroscopy (IR) were used to characterize these composites. Cyclic voltammetry and chronoamperometry technique were used to test the electrical properties of the constructed polyaniline/magnetic graphene laccase modified electrode. The results show that the polyaniline/magnetic graphene immobilizing laccase modified electrode exhibited superior electrical properties, including high sensitivity, detection limit and linear range. The hydroquinone was used as an analytical and detection probe. The selectivity was 0.03639 A/(mol/L), the linear range was 0.4-337.2 μmol/L, and the detection limit was 2.94 μM (signal/noise = 3, minimum identification value of effective signal). The biosensor can reach the conditions for detecting the actual water sample. V.A biocompatible and antibacterial scaffold with efficient wound healing activity can be an appropriate option for wound dressing application. In this study, polyurethane-hyaluronic acid (PU-HA) nanofibrous wound dressing was fabricated and then enriched with three different concentrations of ethanolic extract of propolis (EEP). The obtained samples were characterized by attenuated total reflectance/Fourier transform infrared spectroscopy, thermal gravimetric analysis, scanning electron microscopy, mechanical investigations, antibacterial tests, water uptake exam, and in vitro and in vivo evaluations. The PU-HA/1% EEP and PU-HA/2% EEP samples exhibited higher antibacterial activity against Staphylococcus aureus (2.36 ± 0.33 and 5.63 ± 0.87 mm), Escherichia coli (1.94 ± 0.12 and 3.18 ± 0.63 mm) in comparison with other samples. However, the PU-HA/1% EEP sample exhibited significantly higher biocompatibility for L929 fibroblast cells in comparison with PU-HA/2% EEP. Also, the PU-HA/1% EEP sample could significantly accelerate the wound healing progression and wound closure at the animal model. At the histopathological analyses, improved dermis development and collagen deposition at the healed wound area of the PU-HA/1% EEP sample in comparison with other groups was observed. These results indicate that 1 wt% EEP enriched PU-HA nanofibrous scaffold can be a promising candidate with considerable biocompatibility, wound healing, and antibacterial activities for further biomedical applications. The rapid progress of nanotechnology triggers the development of nanomedicine. As the antimicrobial properties of nanosilver are well known, there is a huge interest in the synthesis of silver nanoparticles using environmentally-friendly methods. In this study we described the functional (rheological, mechanical, surface, structural) properties of gels and foils containing silver nanoparticles embedded in hyaluronan and hyaluronan-lecithin matrix prepared using the methods of green chemistry. The study showed that the addition of silver strengthened the structure of Hyal foil, but reduced the stretch of the sample and that lecithin weakened the mechanical properties of the composites. Also, the presence of nanosilver made the studied foils partially hydrophilic, while these with lecithin were more hydrophobic. The results of the study are significant for the adaptation of the investigated materials to their potential applications. In silico modelling of cascade enzymatic proteolysis is an exceedingly complex and challenging task. Here, we study partial proteolysis of insulin by pepsin a process leading to the release of a highly amyloidogenic two chain 'H-fragment'. The H-fragment retains several cleavage sites for pepsin. However, under favorable conditions H-monomers rapidly self-assemble into proteolysis-resistant amyloid fibrils whose composition provides snapshots of early and intermediate stages of the proteolysis. In this work, we report a remarkable agreement of experimentally determined and simulation-predicted cleavage sites on different stages of the proteolysis. Prediction of cleavage sites was based on the comprehensive analysis of the docking interactions from direct simulation of coupled folding and binding of insulin (or its cleaved derivatives) to pepsin. The most frequent interactions were found to be between the pepsin's active site, or its direct vicinity, and the experimentally determined insulin cleavage sites, which suggest that the docking interactions govern the proteolytic process.
