VIEW, EarlyView.The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Comments on : diet, physiology and ecology of fossil mammals as inferred from stable carbon and nitrogen isotope biogeochemistry: implications for Pleistocene bears [PDF]
, 1997 A detailed study of isotopic relationships in European Pleistocene ursid teeth have been presented by Bocherens et al. (1994). We agree with the resu1ts and broad conclusions derived from the stable carbon isotope relationships.

Wildlife Biology, EarlyView.The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety
High Voltage, EarlyView.ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ungulate body fat reserves reflect the nutritional environment, often serving as a useful indicator of bottom‐up resource availability. However, body fat reserves also integrate energetic costs associated with avoiding predation risk and reproductive effort, and it is ...
