Reconciling competing models on the roles of condensates and soluble complexes in transcription factor function.

Phase separation explains the exquisite spatial and temporal regulation of many biological processes, but the role of transcription factor-mediated condensates in gene regulation is contentious, requiring head-to-head comparison of competing models. Here, we focused on the prototypical yeast transcription factor Gcn4 and assessed two models for gene transcription activation, i.e.

Sequence-specific interactions determine viscoelasticity and aging dynamics of protein condensates.

Biomolecular condensates are viscoelastic materials. Here, we investigate the determinants of sequence-encoded and age-dependent viscoelasticity of condensates formed by the prion-like low-complexity domain of the protein hnRNP A1 and its designed variants. We find that the dominantly viscous forms of the condensates are metastable Maxwell fluids.

Measuring guideline adherence in physiotherapy: A scoping review of methodological approaches.

Rationale: Clinical practice guidelines summarise the existing evidence on specific health conditions and aim to optimise quality of care by providing evidence-based recommendations. Studies have reported a gap between research findings and clinical practice in physiotherapy. Guideline adherence is often used as a measure of agreement between therapeutic care and guideline recommendations.
