Summary: In this paper, the adsorption process of bovine serum albumin (BSA) on the [p(HEMA)-g-CTS]/MMT superabsorbent nanocomposite was investigated. The [p(HEMA)-g-CTS]/MMT superabsorbent nanocomposite was synthesized using free radical polymerization. Various techniques, such as FTIR, SEM, TGA, and swelling test, were employed to characterize the structure of the synthesized [p(HEMA)-g-CTS]/MMT superabsorbent nanocomposite. The influence of adsorption parameters on the adsorption process was evaluated and the results showed that the superabsorbent nanocomposite had a high affinity to BSA.

Summary: In order to enhance the flame retardancy and thermal conductivity of SBR, microcapsules of flame retardant and thermal conductive additive EG (BN-PPEG) were prepared by doping BN with HEMAP. The addition of 15 phr BN-PPEG resulted in a 58.0% increase in thermal conductivity and a 38.5% increase in LOI value compared to pure SBR. Additionally, the pHRR of the composites decreased by 53.9% compared to pure SBR, attributed to the physical barrier of BN and EG, the capture of active free radicals by HEMAP, and the promotion of SBR carbonization by phosphoric acid and metaphosphoric acid.

Summary: This study aimed to elucidate the peculiarities of fullerene C-60 interactions with bovine serum albumin in mixed layers at the water-air interface. The results revealed strong interactions between components in the surface layer, leading to non-monotonic kinetic dependences of dynamic surface elasticity. Observations showed different contributions of protein and fullerene at different surface pressure regions, with distinct morphology in aggregates between the two systems.

Summary: The interactions between ZnO and BSA on different surfaces play a crucial role in determining the roughness, thickness, and adhesion properties of the protein layer. The specific surface structure of ZnO affects the arrangement of BSA and the binding between amino acids and ZnO, ultimately controlling the electronic effects in the BSA-ZnO complexes. This facet-specific protein binding can offer insights for improving the design and functionality of ZnO-based materials and devices.

Summary: The surface properties of aqueous dispersions of worm-like fibril aggregates of bovine serum albumin (BSA) differ from those of the adsorption layers of the native protein. The dispersions of BSA fibrils are characterized by slower changes in surface tension and dynamic surface elasticity and also have different steady-state values of the surface properties. The compression of the adsorption layer of BSA fibrils results in higher surface pressures compared to compressed layers of the native protein, indicating a more rigid layer structure in the former case. Spreading BSA fibrils onto a liquid surface from a concentrated dispersion reduces the effect of surface-active admixtures on the layer properties. The dynamic surface elasticity of the spread layers of fibrils and the native protein almost coincide at low surface pressures, but only spreading of the native protein can lead to surface pressures higher than 4 mN/m. This distinction is presumably due to the formation of stable clusters of BSA fibrils at the interface and their slow propagation along the liquid surface.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.

Under optimized conditions, the PER-E-CRISPR assay exhibits a linear range from 10-13 to 10-7 M and a limit of detection of 30.2 fM. The biosensor shows excellent performance in actual plasma, indicating promising prospects for miRNA detection in molecular diagnosis.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
