Particle-associated dissolved elemental fluxes: revising the stochiometry of mixed layer export

open access: yes, 2005
International audienceSinking particles carry substantial loads of dissolved elements in their interstitial spaces that contribute to the vertical transport of elements out of the euphotic zone.

Surface wear and roughness of experimental composites containing calcium orthophosphate particles following toothbrush abrasion

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This study evaluated experimental composites containing dicalcium phosphate dihydrate (DCPD) particles for toothbrush wear and roughness. Composites containing bisphenol‐A glycidyl dimethacrylate/triethylene glycol dimethacrylate with 50 vol% inorganic fraction consisting of barium glass and DCPD (35:15 and 15:35 vol%) or barium glass only ...

Use of the oral microbiota as screening test to identify children at risk for caries development. A systematic review of longitudinal studies

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This study investigated trends in oral microbiota composition (index test) that could indicate potential candidates to identify children at risk for dental caries development compared with visual/tactile examination (reference test). MEDLINE/PubMed, Web of Science, Embase, Scopus, Lilacs, SciELO, and Google Scholar databases were searched up ...

Influence of Hyaluronic Acid in Periodontal Tissue Regeneration [PDF]

open access: yes, 2013
Hyaluronic acid is a high molecular weight polysaccharide - glycosaminoglycan, which plays a vital role in the functioning of extracellular matrices, including those of mineralized and non-mineralized periodontal tissues.

Trophic Changes off Southwest Greenland During the Holocene and Their Influence on Carbon Burial

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Organic carbon (OC) burial in sediments is partly controlled by catabolic biodegradation and remineralization by heterotrophic bacteria, but long‐term records of these bacterially‐mediated processes have not been available. Here, we use stable hydrogen isotope ratio of the saturated C16 fatty acid (δ2HC16:0) as a proxy of the prevalence of ...

Sources and emission of greenhouse gases in Danube Delta lakes [PDF]

open access: yes, 2018
Production of methane and carbon dioxide as well as methane concentrations in surface waters and emissions to the atmosphere were investigated in two flow-through lake complexes (Uzlina-Isac and Puiu-Rosu-Rosulet) in the Danube Delta during post-flood ...

Modeling Variability in Vertical Profiles of Particulate Organic Carbon Flux

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The vertical flux of particulate organic carbon (POC) from the surface to the deep ocean regulates the ocean carbon uptake, with implications for the Earth's carbon cycle. It is debated in the literature what functional form best describes the attenuation of this flux with depth.
