CRISPR-Cas12a system, characterized by its precise sequence recognition and cleavage activity, has emerged as a powerful and programmable tool for molecular diagnostics. However, current CRISPR-Cas12a-based nucleic acid detection methods, particularly microRNA (miRNA) detection, necessitate additional bio-engineering strategies to exert control over Cas12a activity. Herein, we propose an engineered target-responsive hairpin DNA activator (TRHDA) to mediate forward tearing protospacer activated CRISPR-Cas12a system, which enables direct miRNA detection with high specificity and sensitivity.

Background: We explored the efficacy and safety of esketamine combined with propofol for conscious sedation in painless colonoscopy.

Methods: A total of 195 patients who underwent painless colonoscopy surgery were randomly divided into three groups: the propofol deep sedation group (group DS), the sufentanil combined with propofol for conscious sedation (group CS) and the esketamine combined with propofol for conscious sedation (group CS). The primary outcomes of this study included the incidence of hypoxemia, hypotension, hypertension, and bradycardia and excellent and good rates of anaesthesia during colonoscopy.
