Structural RNAs exhibit a vast array of recurrent short 3D elements involving non-Watson-Crick interactions that help arrange canonical double helices into tertiary structures. We present CaCoFold-R3D, a probabilistic grammar that predicts these RNA 3D motifs (also termed modules) jointly with RNA secondary structure over a sequence or alignment. CaCoFold-R3D uses evolutionary information present in an RNA alignment to reliably identify canonical helices (including pseudoknots) by covariation.

The Hypotension Prediction Index (HPI) may aid in managing intraoperative hemodynamic instability. This study assessed if HPI-guided therapy reduces moderate-to-severe AKI incidence in moderate-to-high-risk elective abdominal surgery patients.

- Transcutaneous auricular vagus nerve stimulation (tVNS) may be an innovative treatment for knee osteoarthritis (OA), investigating its safety and preliminary effects on pain relief.
- A pilot trial with 30 participants found significant reductions in knee pain immediately and shortly after tVNS, with improvements in conditioned pain modulation and heart rate variability, indicating better parasympathetic function.
- While tVNS shows promise as a non-invasive pain-relief option for knee OA, further research with larger samples is necessary to validate these findings.
Article Synopsis
- Rigid spine syndrome is a rare condition in children marked by progressive scoliosis, neck and spine stiffness, muscle weakness, and breathing issues, primarily linked to genetic variations in the SELENON gene.
- Recent research identified additional genetic variants in the HMGCS1 gene in five patients, suggesting it plays a role in this syndrome, despite it not being previously linked to any diseases.
- Functional studies of the HMGCS1 variants showed altered protein stability and activity, and experiments in zebrafish indicated that these mutations severely impact development, but can be rescued by introducing healthy HMGCS1 mRNA.
The Rfam database, a widely used repository of non-coding RNA families, has undergone significant updates in release 15.0. This paper introduces major improvements, including the expansion of Rfamseq to 26 106 genomes, a 76% increase, incorporating the latest UniProt reference proteomes and additional viral genomes.
