Evolutionary insights into bilin biosynthesis: Functional characterization of pre‐PcyA enzymes

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Biosynthesis of the linear tetrapyrrole phycocyanobilin (PCB) by the ferredoxin‐dependent bilin reductase (FDBR) PcyA is essential for light‐harvesting and regulatory processes in diverse photosynthetic organisms, yet its evolutionary origins are not fully understood. PcyA evolved from pre‐PcyA proteins found in diverse bacteria.

Occlusal Dysesthesia: Identifying Knowledge Gaps to Advance Clinical Care

open access: yesJournal of Oral Rehabilitation, Volume 53, Issue 9, Page 1746-1756, September 2026.
This scoping review highlights major knowledge gaps in the understanding of occlusal dysesthesia, including limited evidence on sensory, psychological and neurobiological mechanisms. Current theories remain largely unverified, underscoring the need for integrated biopsychosocial research to improve diagnosis and patient care.

Biocatalytic Application of Goodfellowiella coeruleoviolacea Imine Reductase: Enantioselective Synthesis of Cyclic Secondary Amines in Deep Eutectic Solvent‐Based Media

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A Goodfellowiella coeruleoviolacea Imine Reductase is here reported as a novel enzyme for biocatalytic application in chiral amine synthesis. Deep eutectic solvents have been used to increase substrate loadings, up to 150 mM, and boost enzymatic activity. Reaction scope and scale‐up procedure showcased the protocol applicability.

Addressing the How of Implementation: A Hermeneutic Exploration of Implementing Virtual Kidney Care in a Remote, Rural Health Region

open access: yesJournal of Evaluation in Clinical Practice, Volume 32, Issue 5, August 2026.
ABSTRACT Rationale Implementing evidence‐informed healthcare services is typically approached as a structured, time‐limited project, focused largely on what to do. Less well understood is how implementation actually unfolds in practice: the ways in which those involved navigate change and generate solutions in diverse community settings.
