At the same time, the existence of PEG200 can effectively increase the stability and elasticity of the coating and maintain its mechanical properties after UV irradiation. Furthermore, the coating could maintain highly UV-protective performance and could be transparent even after thermal treatment at high temperature (973 K). From this point of view, the hybrid materials have considerable application potential in next-generation UV protective coatings, especially with their utilization in heat-sensitive substrates or under high-temperature conditions.Coiled-coil protein origami (CCPO) polyhedra are designed self-assembling nanostructures constructed from coiled coil (CC)-forming modules connected into a single chain. For testing new CCPO building modules, simpler polyhedra could be used that should maintain most features relevant to larger scaffolds. We show the design and characterization of nanoscale single-chain triangles, composed of six concatenated parallel CC dimer-forming segments connected by flexible linker peptides. The polypeptides self-assembled in bacteria in agreement with the design, and the shape of the polypeptides was confirmed with small-angle X-ray scattering. Fusion with split-fluorescent protein domains was used as a functional assay in bacteria, based on the discrimination between the correctly folded and misfolded nanoscale triangles comprising correct, mismatched, or truncated modules. This strategy was used to evaluate the optimal size of linkers between CC segments which comprised eight amino acid residues.MicroRNAs are potential targets for drug development. Small molecules that can inhibit or promote a specific miRNA’s biogenesis would be useful for regulating its target genes. Various types of small molecules have been investigated so far for their potential application in modulating miRNA biogenesis. They bind to the target primary or precursor miRNAs and inhibit the processing of these precursors by Drosha or Dicer. However, the binding site that effectively interferes with the Dicer cleavage reaction is still undetermined. Here we report that our designed small molecule restricted naphthyridine dimer (RND) binds to the hairpin loop of a hairpin RNA and induces its dimerization. This study shows that the binding of the RND to the hairpin loop was not effective in interfering with the Dicer cleavage reaction, but dimerization of the hairpin RNA by RND binding effectively interfered with the Dicer cleavage reaction.Metal-organic gels (MOGs) are new soft materials with the characteristics of high colloidal stability, superb luminescence properties, and facile synthesis. Herein, we develop for the first time a host-guest interaction-based and MOG-based biosensor with aggregation-induced electrochemiluminescence (ECL) enhancement for M.SssI methyltransferase (M.SssI MTase) assay. This biosensor employs a MOG as the luminophor and potassium persulfate as the coreactant, and the formation of the Ag-MOG from the aggregation of silver nanoclusters can induce significant ECL enhancement. Two complementary single-stranded DNAs (ssDNAs, i.e., biotinylated DNA-1 and Fc-labeled DNA-2) that contain specific recognition sequence 5′-CCGG-3′ can form a double-stranded DNA (dsDNA) probe. In the absence of M.SssI MTase, the dsDNA probe will be digested by restriction endonuclease HpaII, leading to the release of Fc from magnetic beads (MBs). The β-CD can specifically recognize the released Fc through guest-host interaction, resulting in the quenching of an ECL signal. In contrast, the presence of M.SssI MTase enables the formation of fully methylated dsDNA, which cannot be cleaved by HpaII, making Fc remain on the MB surface and consequently generating an improved ECL signal. This biosensor can specifically detect M.SssI MTase with a linear range of 0.05-100 U mL-1 and a limit of detection of 3.5 × 10-3 U mL-1, and it enables accurate detection of M.SssI MTase in human serum. In addition, it can be used for inhibitor screening, with wide applications in drug discovery and disease diagnosis.This paper describes the scientific career and accomplishments of Professor Wladek Minor, who holds an endowed chair at the University of Virginia in Charlottesville, USA.

Mindfulness and acceptance have demonstrated associations with alexithymia facets. As a very limited body of research has explored the predictive strength among alexithymia-related constructs, this study aimed to investigate the prediction of alexithymia based on acceptance and mindfulness among students. The study group consisted of 586 university students, 237 (40.9%) females and 349 (59.1%) males. As for data collection, the five-factor mindfulness questionnaire, Acceptance and Commitment Questionnaire, and the Toronto Alexithymia Scale-2 were applied. A stepwise multiple linear regression was calculated to predict alexithymia based on components of commitment and action, mindfulness facets, and demographic variables (F[5,578] = 77.26, p ≤ 0.001), with an R2 of 0.41. The predictive variables including description (B = -0.59, t = -8.02, p < 0.001), commitment and action (B = -0.13, t = -4.38, p < 0.001), observation (B = -0.15, t = -2.94, p < 0.01), and no judgment (B = -0.16, t = -2.56, p < 0ographic variables (F[5,578] = 77.26, p ≤ 0.001), with an R2 of 0.41. The predictive variables including description (B = -0.59, t = -8.02, p less then 0.001), commitment and action (B = -0.13, t = -4.38, p less then 0.001), observation (B = -0.15, t = -2.94, p less then 0.01), and no judgment (B = -0.16, t = -2.56, p less then 0.05) exhibited significant prediction effects on the adjusted index of alexithymia. The findings contribute to the potential mechanism between mindfulness and alexithymia in intervention that seeks to improve mindfulness and acceptance skills and could prove more effective in treating patients with alexithymia.
