Effects of fluoride on in vitro hydroxyapatite demineralisation analysed by 19F MAS-NMR

open access: yesFrontiers in Dental Medicine, 2023
IntroductionFluoride plays a major role in inhibiting enamel dissolution and promoting fluorapatite formation. Porous hydroxyapatite (HAP) discs can be used as an enamel analogue in artificial demineralisation/remineralisation studies.MethodThe aim of ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

open access: yesThe Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS): fieldwork, synthesis and modelling efforts

open access: yesFrontiers in Marine Science, 2016
The ocean’s biological carbon pump plays a central role in regulating atmospheric CO2 levels. In particular, the depth at which sinking organic carbon is broken down and respired in the mesopelagic zone is critical, with deeper remineralisation resulting
