Cell entry by enveloped viruses involves a set of multistep, multivalent interactions between viral and host proteins as well as manipulation of nanoscale membrane mechanics by these interacting partners. A mechanistic understanding of these events has been challenging due to the complex nature of the interactions and the event-to-event heterogeneity involved. Single-virus microscopy has emerged as a powerful technique to probe viral binding and fusion kinetics.

Construction and optimization of stable atomically dispersed metal sites on SiO surfaces are important yet challenging topics. In this work, we developed the amino group-assisted atomic layer deposition strategy to deposit the atomically dispersed Pt on SiO support for the first time, in which the particle size and ratio of Pt entities from single atom (Pt) to atomic cluster (Pt ) and nanoparticle (Pt ) on the SiO surface were well modulated. We demonstrated the importance of dual-site synergy for optimizing the activity of single-atom catalysts.

Purpose: To improve the oral absorption of relugolix (RLGL), which has low oral bioavailability due to its low solubility and being a substrate of P-glycoprotein (P-gp). A solid self-microemulsifying drug delivery system of relugolix (RLGL-S-SMEDDS) was prepared and evaluated in vitro and in vivo.
Methods: The composition of the solid self-microemulsifying drug delivery system (S-SMEDDS) was selected by solubility study and pseudo-ternary phase diagram, and further optimized by Design-Expert optimization design.
The classification of chronic diseases has long been a prominent research focus in the field of public health, with widespread application of machine learning algorithms. Diabetes is one of the chronic diseases with a high prevalence worldwide and is considered a disease in its own right. Given the widespread nature of this chronic condition, numerous researchers are striving to develop robust machine learning algorithms for accurate classification.

Rutin, a promising bioactive hydrophobic compound, suffers from poor physicochemical stability, resulting in low bioavailability. Herein, we used positively charged chitosan and negatively charged fucoidan as biopolymers coating rutin-nanoliposome (RNL) via electrostatic layer-by-layer self-assembly approach to prepare fucoidan/chitosan-coated rutin-nanoliposome (FC-RNL). The FC-RNL exhibited the encapsulation efficiency of 77.
