This paper reports the preparation of a library of unsymmetrical ureas based on 8-azabicyclo[3.2.1]octane scaffold. The reported synthetic route uses nortropane-8-carbonyl chlorides as key intermediates that, when treated with a slight excess of amine, give the corresponding ureas in high yield (129 examples).

An enzyme with strong single-stranded DNA (ssDNA) ligation activity would be advantageous for many molecular biology applications. However, currently available enzymes exhibit only limited activity. Here, we identified an enzyme with strong ssDNA ligation activity upon searching the databases for proteins homologous to TS2126 RNA ligase, the known enzyme with the highest yet limited ssDNA ligation activity.

DNA and RNA markers are significant in forensic practices, such as individual and body fluid identification. However, forensic DNA and RNA markers were separately analyzed in most forensic experiments, which resulted in large amounts of sample consumption, complex procedures, and weak inter-evidence correlation. While several integrated methods based on capillary electrophoresis and next-generation sequencing technologies were reported, integrated procedures were mostly on nucleic acid co-extraction, co-electrophoresis, or co-sequencing, and the number and type of markers co-tested were limited.

Background: Diastasis recti abdominis (DRA), commonly occurring in postpartum women, is not only an aesthetic issue but is also highly associated with functional impairments. Various conservative treatment modalities have been employed in clinical practice to alleviate DRA. However, the comparative efficacy of these non-surgical treatments for improving the inter-recti distance (IRD) remains to be determined.

Purpose: Guided access cavity preparation (GACP) is an endodontic procedure utilizing stents, guide sleeves, or dynamic guides to facilitate the proper formation of access cavities. This paper aims to evaluate the significance of research on guided access cavity preparation in endodontic treatment concerning dentin preservation. In the context of dentin preservation, this paper provides a thorough scoping review of a variety of methodologies for evaluating the accuracy of guided access cavity preparation.
