Navigating Children's Risky Play: A Comparative Analysis of Saudi Mothers and Fathers.

Despite documented benefits for development, children are engaging in considerably fewer risky play activities. Research on parent gender and children's risky play is inconsistent. Gender and cultural context shape how individuals perceive and tolerate children's risky play.

Assessment of Favipiravir and Remdesivir in Combination for SARS-CoV-2 Infection in Syrian Golden Hamsters.

Favipiravir (FVP) and remdesivir (RDV) have demonstrable antiviral activity against SARS-CoV-2. Here, the efficacy of FVP, RDV, and FVP with RDV (FVP + RDV) in combination was assessed in Syrian golden hamsters challenged with SARS-CoV- 2 (B.1.

Silver Oxide Promoted Synthesis of Alpha -GalNAc Containing Glyco-Amino Acids: Synthesis of Core 2 Containing Glyco-Amino Acids for Solid Phase Synthesis of Glycopeptides.

-GalNAc glycans on glycoproteins with eight different core structures sharing a common α-glycosidic linkage (-GalNAc-α-Ser/Thr) are critical in various physiological and pathological processes. Among the eight -GalNAc glycan cores, core 2 characterized by a GlcNAcβ1-6(Galβ1-3)GalNAc structural motif plays a significant role in regulating diverse biological processes, such as immune response modulation, adhesive properties of selectins, and gastrointestinal tract protection. However, the large-quantity synthesis of core 2 containing glyco-amino acids for downstream solid-phase peptide synthesis is challenging.

Design of high specificity binders for peptide-MHC-I complexes.

Class I MHC molecules present peptides derived from intracellular antigens on the cell surface for immune surveillance, and specific targeting of these peptide-MHC (pMHC) complexes could have considerable utility for treating diseases. Such targeting is challenging as it requires readout of the few outward facing peptide antigen residues and the avoidance of extensive contacts with the MHC carrier which is present on almost all cells. Here we describe the use of deep learning-based protein design tools to design small proteins that arc above the peptide binding groove of pMHC complexes and make extensive contacts with the peptide.

Tracking flaviviral protease conformational dynamics by tuning single-molecule nanopore tweezers.

The flaviviral NS2B/NS3 protease is a conserved enzyme required for flavivirus replication. Its highly dynamic conformation poses major challenges but also offers opportunities for antiviral inhibition. Here, we established a nanopore tweezers-based platform to monitor NS2B/NS3 conformational dynamics in real time.
