Background: During the recent pandemic with the severe acute respiratory syndrome-corona virus‑2 the first messenger ribonucleic acid (mRNA) vaccines were approved. To facilitate mass vaccination, confidence of the general population in these new vaccines is mandatory, which is in turn strongly dependent on the availability of reliable data on complications.
Objective: Summary of the current knowledge on mRNA vaccination-associated myocarditis as a potentially fatal side effect.
Methods: Systematic literature review.
Results: Diagnostic algorithm for the postmortem diagnosis of mRNA vaccination-associated myocarditis.
Conclusion: Autopsy series of fatalities following mRNA SARS-CoV‑2 vaccination up to 6 weeks with subsequent sophisticated and interdisciplinary work-up are necessary to complement clinical data on vaccination-associated myocarditis, especially regarding the incidence of fatal courses.

U6 snRNA (small nuclear ribonucleic acid) is a ribozyme that catalyzes pre-messenger RNA (pre-mRNA) splicing and undergoes epitranscriptomic modifications. After transcription, the 3'-end of U6 snRNA is oligo-uridylylated by the multi-domain terminal uridylyltransferase (TUTase), TUT1. The 3'- oligo-uridylylated tail of U6 snRNA is crucial for U4/U6 di-snRNP (small nuclear ribonucleoprotein) formation and pre-mRNA splicing.

Ion exchange chromatography (IEX) is an important analytical technique for the characterization of biotechnology-derived products, such as monoclonal antibodies (mAbs) and more recently, cell and gene therapy products such as messenger ribonucleic acid (mRNA) and adeno-associated viruses (AAVs). This review paper first outlines the basic principles and separation mechanisms of IEX for charge variant separation of biotherapeutics, and examines the different elution modes based on salt or pH gradients. It then highlights several recent trends when applying IEX for the characterization of biotechnology-derived products, including: i) the effective use of pH gradients, ii) the improvement of selectivity by using organic solvents in the mobile phase, multi-step gradients, or by combining ion pairing and ion exchange, and iii) the increase in analytical throughput using ultra-short columns or automated screening of conditions.

Psoriasis (PsO) is a chronic immune-mediated disease of the skin. Psoriatic arthritis (PsA) is a prevalent chronic inflammatory disease that is associated with joint destruction and disability. The presence of PsO is the single greatest risk factor for the development of PsA.

First believed to be a simple intermediary between the information encoded in deoxyribonucleic acid and that functionally displayed in proteins, ribonucleic acid (RNA) is now known to have many functions through its abundance and intricate, ubiquitous, diverse, and dynamic structure. About 70-90% of the human genome is transcribed into protein-coding and noncoding RNAs as main determinants along with regulatory sequences of cellular to populational biological diversity. From the nucleotide sequence or primary structure, through Watson-Crick pairing self-folding or secondary structure, to compaction via longer distance Watson-Crick and non-Watson-Crick interactions or tertiary structure, and interactions with RNA or other biopolymers or quaternary structure, or with metabolites and biomolecules or quinary structure, RNA structure plays a critical role in RNA's lifecycle from transcription to decay and many cellular processes.
