Despite numerous viral outbreaks in the last decade, including a devastating global pandemic, diagnostic and therapeutic technologies remain severely lacking. CRISPR-Cas systems have the potential to address these critical needs in the response against infectious disease. Initially discovered as the bacterial adaptive immune system, these systems provide a unique opportunity to create programmable, sequence-specific technologies for detection of viral nucleic acids and inhibition of viral replication. This review summarizes how CRISPR-Cas systems-in particular the recently discovered DNA-targeting Cas12 and RNA-targeting Cas13, both possessing a unique trans-cleavage activity-are being harnessed for viral diagnostics and therapies. We further highlight the numerous technologies whose development has accelerated in response to the COVID-19 pandemic.

Bisphenol F (BPF) has become a new risk factor for male semen quality, but its specific mechanism is still unclear. Therefore, this study explored the potential mechanism of BPF affecting male semen quality from the perspective of ferroptosis and m6A RNA methylation. In vivo experiments showed that BPF destroyed the structure of seminiferous tubules, reduced the layers of spermatogenic cells, and reduced semen quality in mice.

A lanthanide ion-based metal-organic framework (Eu-TATAB nanorods) was designed and synthesized as an effective tri-mode nanoprobe for sensitive and portable detection of ethanol content in a water-ethanol mixture. The assay was based on the responsive properties of Eu-TATAB nanorods to ethanol stimulus and their adaptive encapsulation capability towards optically active lanthanides. With the addition of ethanol to the Eu-TATAB nanorods, the structure was destroyed, resulting in a decrease in luminescence, electrochemiluminescence, and ultraviolet-visible spectrophotometric signals by perturbing energy transfer in the Eu-TATAB nanorods.

Objective: The difficulty of establishing slow release at intestinal infection sites, weak antibacterial effects, as well as the limited broad use of florfenicol oral formulations are the main targets of the current study. Novel hydrogels derived from sodium alginate were developed using a complexation form for florfenicol delivery to achieve slow release at the site of intestinal infection and enhance its antibacterial activity against .
Methods: The optimal formulation, physicochemical properties, stability, pH-responsive performance, antibacterial activity, and in vitro biosafety of the florfenicol hydrogels have been studied systematically.
