The development of multifunctional and low-cost hydrogel dressings with good mechanical properties, antibacterial activity, and nontoxicity is of great relevance in healthcare. This study aimed to prepare a series of hydrogels consisting of maltodextrin (MD), polyvinyl alcohol (PVA), and tannic acid (TA) through a freeze-thaw cycling technique. Micro-acid hydrogels with different mass ratios (0, 0.

Exploring efficient cocatalysts capable of accelerating surface catalytic reaction is of great significance for the development of solar-driven hydrogen production. Herein, on the basis of NiFe hydroxide, we developed a series of Pt doped NiFe-based cocatalysts to promote the photocatalytic hydrogen production of graphitic carbon nitride (g-C N ). We find that the Pt doping can trigger phase reconstruction of NiFe hydroxide and lead to the formation of NiFe bicarbonate, which displays higher catalytic activity toward hydrogen evolution reaction (HER).

In previous decades, patients with the most active EGFR mutations in non-small cell lung cancer (NSCLC) have significantly benefited from EGFR tyrosine kinase inhibitors (TKIs). However, a minority with EGFR and HER2 exon 20 mutations are inherently resistant to treatment. Several molecular TKIs (such as TAK788 and Poziotinib) were recently discovered and demonstrated as effective inhibitors against the most prevalent HER2 or EGFR exon 20 mutations.

Herein, V-doped cobalt hydroxides grown on carbon cloth (V-Co(OH)/CC) were prepared hydrothermal method. The incorporation of V can trigger phase transition and tune the local electronic structure of Co(OH), thereby improving the intrinsic alkaline HER activity. We find that the V-Co(OH) dominated by β-Co(OH) exhibits excellent HER activity with only 83 mV overpotential at a current density of 10 mA cm, which outperforms most reported hydroxide-based catalysts and even surpasses the commercial Pt/C at large current density (>160 mA cm).

We previously identified an HIV-1 fusion inhibitor P20A targeting HIV-1 gp41 6-HB fusion core. Using alanine scanning mutagenesis, we investigated the effect of 6-HB surface residue mutations on the binding affinity between P20A and 6-HB. Substitution of positively or negatively charged residues in the distal region of 6-HB with alanines resulted in significant decrease or increase of its binding affinity to P20A, respectively.

In this study, a universal protein expression enhancement RNA tool, termed RNAe, was developed by modifying a recently discovered natural long non-coding RNA. At the moment, RNAe is the only technology for gene expression enhancement, as opposed to silencing, at the post-transcriptional level. With this technology, an expression enhancement of 50-1000% is achievable, with more than 200% enhancement achieved in most cases.
