Nanotechnology and synthetic biology are rapidly converging, with DNA origami being one of the leading bridging technologies. DNA origami was shown to work well in a wide array of biotic environments. However, the large majority of extant DNA origami scaffolds utilize bacteriophages or plasmid sequences thus severely limiting its future applicability as a bio-orthogonal nanotechnology platform. In this paper we present the design of biologically inert (i.e., "bio-orthogonal") origami scaffolds. The synthetic scaffolds have the additional advantage of being uniquely addressable (unlike biologically derived ones) and hence are better optimized for high-yield folding. We demonstrate our fully synthetic scaffold design with both DNA and RNA origamis and describe a protocol to produce these bio-orthogonal and uniquely addressable origami scaffolds.

The critical care unit at the University Hospital of Wales is a 38-bedded tertiary center. In 2023, the unit admitted 1251 unscheduled patients, of which 131 were out-of-hospital cardiac arrest (OOHCA) patients. The unit also participated in the Targeted Temperature Management 2 study and adopted the findings shortly after its publication in 2021.

The terminal deoxynucleotidyl transferase is a unique polymerase that incorporates nucleotides at the 3'-terminus of single-stranded DNA primers in a template-independent manner. This biological function propels the development of numerous biomedical and bioengineering applications. However, the extensive use of TdT is constrained by its low expression levels in E.

The seed microbiota, a still underexplored component of plant-microbe interactions, plays a pivotal role in plant development and holds significant promise for advancing sustainable agriculture. By influencing essential processes such as germination, stress tolerance, nutrient acquisition and defence, seed-associated microbes offer unique advantages beyond those of soil- or rhizosphere-associated microbiomes. Notably, they are transmitted both vertically and horizontally; however, fundamental questions remain regarding their origin, ecological dynamics and functional roles across environments.

G-quadruplexes (G4) are four-stranded nucleic acid structures formed within sequences containing repeated guanine tracts separated by intervening loop regions. Abundant in the human genome, they play crucial roles in transcription regulation and genome maintenance. Although theoretically capable to adopt 26 different folding topologies─primarily differing in loop arrangements─only 14 of these have been observed experimentally.

ConspectusWhat does the word antioxidant mean? Antioxidants are supposed to be nontoxic, versatile molecules capable of counteracting the damaging effects of oxidative stress (OS). Thus, when evaluating a candidate molecule as an antioxidant, several aspects should be considered. Antioxidants are more than free radical scavengers.
