The effects of fat loss after bariatric surgery on inflammation, serum hepcidin, and iron absorption: a prospective 6-mo iron stable isotope study
obesity iron deficiency iron absorption hepcidin inflammation stable isotopes
2018/12/14
Background: Iron deficiency is common in obese subjects. This may be due to an increase in serum hepcidin and a decrease in iron absorption from adiposity-related inflammation.

Stable isotope analysis of vertebrae reveals ontogenetic changes in habitat in an endothermic pelagic shark
stable isotope analysis elasmobranch ontogenetic shift satellite tagging stable isotope mixing model
2015/11/16
Ontogenetic changes in habitat are driven by shifting life-history requirements and play an important role in population dynamics. However, large portions of the life history of many pelagic species a...
Can 13C stable isotope record of Norway spruce tree rings display the effect of environmental conditions?
Δ13C air pollution tree physiology Bohemian Forest Mts. soil pH aluminium soil acidification
2015/3/12
The Bohemian Forest Mts. (Šumava) were exposed to heavy atmospheric pollution in the last century. A possible negative effect of atmospheric pollution on tree physiology has been studied using th...
Stable isotope estimates of evaporation : inflow and water residence time for lakes across the United States as a tool for national lake water quality assessments
inflow water residence
2014/11/28
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s
National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...

System for High Throughput Water Extraction from Soil Material for Stable Isotope Analysis of Water
Isotope Vacuum Distillation Soil
2013/1/29
A major limitation in the use of stable isotope of water in ecological studies is the time that is required to extract water from soil and plant samples. Using vacuum distillation the extraction time ...
In this paper we review recent advances in Stable Isotope Mixing Models (SIMMs) and place them into an over-arching Bayesian statistical framework which allows for several useful extensions. SIMMs are...
