CRISPR-Hybrid: A CRISPR-Mediated Intracellular Directed Evolution Platform for RNA Aptamers.

Recent advances in gene editing and precise regulation of gene expression based on CRISPR technologies have provided powerful tools for the understanding and manipulation of gene functions. Fusing RNA aptamers to the sgRNA of CRISPR can recruit cognate RNA-binding protein (RBP) effectors to target genomic sites, and the expression of sgRNA containing different RNA aptamers permit simultaneous multiplexed and multifunctional gene regulations. Here, we report an intracellular directed evolution platform for RNA aptamers against intracellularly expressed RBPs.

A Co-Blended and Compounded Photosensitive Resin with Improved Mechanical Properties and Thermal Stability for Nail Polish Application.

UV-curable bio-based resins are widely used in the UV curing field. However, the current UV-curable bio-based resins for the application of nail polish still have the problems of too high viscosity and insufficiently excellent mechanical properties. In this study, a soybean oil-based acrylate photosensitive resin is synthesized by using epoxidized soybean oil as a raw material and reacting it with acrylic acid.

In Vitro Differentiation of Naive CD4+ T Cells into Pathogenic Th17 Cells in Mouse.

In vitro T cell differentiation techniques are essential for both functional and mechanistic investigations of CD4 T cells. Pathogenic Th17 cells have been linked to a wide range of diseases in recent times, including multiple sclerosis (MS), rheumatoid arthritis, acute respiratory distress syndrome (ARDS), sepsis, and other autoimmune disorders. However, the currently known in vitro differentiation protocols have difficulty achieving high purity of pathogenic Th17 cells, with the induction efficiency often below 50%, which is a key challenge in in vitro experiments.

Factors associated with COVID-19 vaccination coverage in hypertensive patients with Omicron infection in Shanghai, China.

The potential future burden of COVID-19 is determined by the level of susceptibility of the population to infection. The protective effect provided by those previously infected diminishes over several months, while individuals with mixed immunity have the highest degree and persistence of protection.

Identification of indications for albumin administration in septic patients with liver cirrhosis.

Background: Albumin infusion is the primary therapeutic strategy for septic patients with liver cirrhosis. Although recent studies have investigated the efficacy of albumin in the resuscitation stage of septic patients with liver cirrhosis, it remains unclear whether daily albumin administration can improve outcomes. Furthermore, the indications for initiating albumin therapy are not well defined.
