Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...
Oxygen in the deep Strait of Georgia, 1951–2009: The roles of mixing, deep-water renewal, and remineralization of organic carbon
deep Strait of Georgia The roles of mixing
2014/4/2
The concentration of oxygen in the deep Strait of Georgia has declined at a rate of 0.45–1.3 mmol L21
yr21
since 1971 and now seasonally approaches thresholds of biological tolerance. The decline ha...
Remineralization of upper ocean particles: Implications for iron biogeochemistry
Remineralization upper ocean particles iron biogeochemistry
2014/4/17
The role of heterotrophic bacteria in iron recycling, the influence of complexation on iron remineralization,and iron mobilization rates from lithogenic vs. biogenic particulate iron (PFe) were examin...
Effects of a glass-ionomer cement on the remineralization of occlusal caries:an in situ study
Glass ionomer cements Dental enamel Hardness
2009/10/19
This work evaluated the remineralization of demineralized enamel of pits and fissures of human third molars sealed with a glass ionomer cement (Fuji IX, GC Corporation - Japan) or with a Bis-GMA seala...
Enamel remineralization:controlling the caries disease or treating early caries lesions?
Dental caries Dental enamel Tooth remineralization Fluorides
2009/10/16
The emphasis currently given to new technologies for enamel remineralization suggests that the changes in the understanding of the dental caries disease, which occurred in the last century, were eithe...
Effect of three fluoride agents on remineralization and fluoride uptake on enamel lesion
Demineralization Fluoride uptake Human molar enamel Remineraliza
2008/4/19
This study is to compare the fluoride uptake of three fluoride agents and the effect of remineralization on artificial enamel lesions. Eight human third molars were all divided into four slabs. The sl...
Research on the remineralization of partially decalcified enamel surfaces using extracted tooth with calcifying solution
Apatite FT-Raman Remineralization Tooth enamel X-ray diffraction
2008/4/16
OBJECTIVE: The recovery of tooth enamel after acid etching was examined in vitro using enamel powder in order to maximize the contact surface area. METHODS: The weight of the powder decreased due to a...
The effect of xylitol and fluoride on remineralization for primary tooth enamel caries in vitro
Fluoride Primary tooth Remineralization Xylitol
2008/4/16
The effect of fluoride and xylitol on remineralization at the early stage of the enamel caries in primary tooth was studied. The samples were divided into four groups (control, 10% xylitol, 950 ppm Na...
Presence and regulation of alkaline phosphatase activity in eukaryotic phytoplankton from the coastal ocean: Implications for dissolved organic phosphorus remineralization
Presence and regulation alkaline phosphatase activity eukaryotic phytoplankton the coastal ocean Implications for dissolved organic phosphorus remineralization
2014/5/4
The biologically important constituents of the dissolved organic phosphorus (DOP) pool, their bioavailability, and their cycling in coastal systems are still poorly understood. Here we use the enzyme ...
Spatiotemporal patterns of carbon remineralization and bio-irrigation in sediments of Casco Bay Estuary, Gulf of Maine
Spatiotemporal patterns carbon mineralization bio-irrigation in sediments Casco Bay Estuary Gulf of Maine
2014/5/14
We measured the seasonal and spatial rates of organic matter decomposition and pore-water irrigation at four subtidal stations in Casco Bay estuary, Gulf of Maine. Organic carbon decomposition and ass...
