Article Abstract

DNA-based circuitry empowers logic gated operations and amplifications but is restricted to nucleic acid output. Templated reactions enable the translation of nucleic acid cues into diverse small-molecule outputs but are more limited in their amplification. Herein, we demonstrate the coupling of a DNA circuit to templated reactions in order to achieve high levels of amplification in the output of small molecules, in response to nucleic acid input. We demonstrate that the coupling of the DNA circuit to templated reactions allows for the detection of the fM concentration of analyte and can respond with the release of a cytotoxic drug.

Background: Migraine care is often suboptimal owing to undertreatment, variation in clinical outcomes and administration methods among existing treatments, and between- and within-individual heterogeneity in the clinical course of migraine. In response to these challenges, preference studies have been increasingly conducted to inform treatment decision-making and development. However, gaps remain in understanding how treatment preferences have been assessed across different migraine studies.

Background: To improve the molecular diagnostic yield for Aspergillus spp. from respiratory samples, we developed and evaluated a new DNA extraction method directly from respiratory samples combined with in-house Aspergillus real-time PCR.

Methods: We developed a method using beads and resin, where a sample is centrifuged to separate the supernatant and pellet.

Diversity-oriented synthesis (DOS) has emerged as an efficient strategy for constructing diverse compound libraries, facilitating hit or lead identification in the drug discovery process. In parallel, developing diverse transformations at different sites is an appealing strategy to expand the diversity of appendages on scaffolds. Owing to the availability of C-H bonds at multiple sites of pharmacophores, diversity-oriented C-H activation reactions are an ideal approach to realize this goal.

The amplification of detection signals is an important method for improving the sensitivity of electrochemical detection. This study presents an efficient strategy for preparing electrochemical catalytic materials using a simple self-assembly technique to encapsulate Fe single atoms (Fe-SAs) and Ni single atoms (Ni-SAs) in the Cu-benzene-1,3,5-tricarboxylic acid (Cu-BTC) metal-organic framework to form a Cu-BTC@FeNi-SAs catalytic system. Subsequently, Cu-BTC@FeNi-SAs was modified on the surface of a gold electrode, and sulfadiazine was used as a template to prepare a molecularly imprinted polymer (MIP) on the modified electrode.

For some of the COVID-19 vaccines, the drug substances released to market were manufactured differently than those used in clinical trials. Manufacturing nucleoside-modified mRNA (modRNA) for commercial COVID-19 vaccines relies on RNA polymerase transcription of a plasmid DNA template. Previous studies identified high levels of plasmid DNA in vials of modRNA vaccines, suggesting that the removal of residual DNA template is problematic.
