  • We investigated differences in concentrations of selected elements in two invasive carp species as a function of sampling site, fish species, length and trophic differences using stable isotopes ( δ 15 N, δ 13 C). Fish were collected from three different sites, the Illinois River near Havana, Illinois, and two sites in the Mississippi River, upstream and downstream of the Illinois River confluence.

  • ratio
  • The presence of H. pylori infection will be diagnosed using the [13C] Urea Breath Test (UBT), which is based on the collection of breath samples that are analyzed for the ratio of 13CO2/12CO2 using isotope ratio mass spectrometry (IRMS) or non-dispersive infrared spectrometry (NDIRS).

  • inhalation
  • Therefore, there is an urgent need to collect information about the biological effects of nanomaterials so that we can exploit their potential benefits and design safer nanomaterials, while avoiding nanotoxicity as a result of inhalation or skin exposure. (frontiersin.org)
  • However, the immunomodulating effects of nanomaterials through skin exposure have not been adequately discussed compared with the effects of inhalation exposure, because skin penetration by nanomaterials is thought to be extremely low under normal conditions. (frontiersin.org)
