Ps19, a novel chitin binding protein from Pteria sterna capable to mineralize aragonite plates in vitro.

open access: yesPLoS ONE, 2020
Mollusk shell is composed of two CaCO3 polymorphs (calcite and aragonite) and an organic matrix that consists of acetic acid- or ethylenediaminetetraacetic acid (EDTA)-soluble and insoluble proteins and other biomolecules (polysaccharides, β-chitin ...

Synthesis of [3H]muscimol

open access: yesJournal of Labelled Compounds and Radiopharmaceuticals, Volume 68, Issue 9-10, July-August 2025.
A novel synthetic approach for the preparation of [3H]muscimol (48.3 Ci/mmol, 1.8 TBq/mmol) based on the reduction of a suitably protected amide precursor using in situ generated tritioborane (BT3·THF) is reported. The method avoids the use of bulk tritiated water employed in established synthetic protocols and enables safe, reliable, and efficient ...

Diel activity correlates with colour pattern morphology of heterobranch sea slugs

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1165-1179, June 2025.
The authors show that daytime activity fundamentally shapes the appearance of prey animals to potential predators and that colour pattern phenotypes likely associated with visual signalling are predominantly found in diurnal species of sea slugs. This study showcases novel methodology combining comparative phylogenetic analyses, animal vision modelling,

Effect of Aortic Valve Geometry on Leaflet Strain Within a Phantom Silicone Aortic Heart Valve During Closing

open access: yesStrain, Volume 61, Issue 3, June 2025.
ABSTRACT In the United Kingdom, aortic valve stenosis is a common heart condition and the cause of morbidity within the elderly population. A common treatment for aortic valve stenosis is replacement with a prosthetic valve, either mechanical or bioprosthetic, each with its own advantages and limitations.

Evidence for control of cerebral neurovascular function by circulating platelets in healthy older adults

open access: yesThe Journal of Physiology, Volume 603, Issue 11, Page 3379-3404, 1 June 2025.
Abstract figure legend Epidemiological evidence suggests a link between dementia and cardiovascular health, including the regulation of platelets. To investigate this relationship, we examined how platelet reactivity relates to cerebral neurovascular function and systemic vascular reactivity in healthy older adults.
