Population differentiation and temporal changes of carotenoid pigments and stable isotope ratios in the offspring of anadromous and non-anadromous trout Salmo trutta. [PDF]
, 2012 Trout (Salmo trutta) exhibit anadromous and non-anadromous forms which are commonly sympatric. Offspring of the two forms can be separated by differences in characteristics such as stable isotope ratios and carotenoid pigments, which differ due to the ...

Labrador Sea freshening at 8.5 ka BP caused by Hudson Bay Ice Saddle collapse
Nature Communications, 2019 The exact freshwater scenario that caused the 8.2 ka cold event is still debated. This study presents new evidence for a severe Labrador shelfwater freshening 8500 years ago that was caused by the Hudson Bay Ice Saddle collapse following a warming in ...

Synthesis of Stable Isotope Deuterium Labeled Levofloxacin-D3
Journal of Isotopes, 2023 In order to improve the stable isotope utilization rate, a simple and inexpensive synthesis method was developed. The synthesis of levofloxacin is based on piperazine as the starting material, and the reaction with carbobenzoxy chloride (CBZ-Cl) to get ...
