A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

Review on the toxic effect of fluorine and lead on lichen metabolism

open access: yesInternational Journal of Secondary Metabolite
Thanks to their ability to absorb large amounts of trace elements from the atmosphere, lichens are widely used as bioaccumulators and bioindicators of air pollution.

New Interpretative Scales for Lichen Bioaccumulation Data: The Italian Proposal

open access: yesAtmosphere, 2019
The interpretation of lichen bioaccumulation data is of paramount importance in environmental forensics and decision-making processes. By implementing basic ideas underlying previous interpretative scales, new dimensionless, species-independent &ldquo ...

Small‐Scale Topographic Variability Shapes Molecular Diversity of Organic Matter in Coastal Dune Soils

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Topography shapes ecosystem controls, driving microclimate, hydrology, and vegetation, which, in turn, influence topsoil traits and DOM composition in coastal dune soils. Distinct molecular patterns emerge across north‐facing and south‐facing slopes and dune valleys.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.
