The impact of acute exposure to sampled groundwater was investigated by treating 21 PND CD1 mice for 3 months.
Research (e.g., Bardovi-Harlig, Hartford, Mahan-Taylor, Morgan, & Raynolds 1991; Cutting, 2008; Huang, 2010) suggests that language learners need pragmatic instruction to gain exposure to samples of social, cultural, and discourse conventions of the target language.
In these parthenogenetically reproducing snails, offspring numbers (prior and after development of a visible shell) as well as mortality are determined after exposure to samples from the five test systems and to surface water and sediment samples of the five field sites.
Results obtained by using this test showed that all samples were not toxic on brine shrimp larvae; in fact after 24 h of exposure to samples at concentration of 100, 10 and 1 μg/ml, all larvae were live and motile.
The 3 T3 NRU test for phototoxicity requires 60-min exposure to sample dilutions in EBSS followed by exposure to UVA light (5 J.cm-2; SOL-500 Sun Simulation System; Dr Honle, Planegg, Germany) of one of the plates.
Because cortisol should be lowest during the rest phase and may be impacted by light exposure, we assessed whether the duration of light exposure prior to sampling correlated with cortisol measures.
Sexual stage antibody prevalence and concentration were related to recent cumulative exposure to gametocytes prior to sampling.
After every sample analysis, the fiber was reanalyzed (without exposure to a sample) to ensure complete desorption of analytes.
The duration of light exposure prior to sampling was not correlated with cortisol concentrations (R2 = 0.00000185, P = 0.995), suggesting that light exposure did not impact the cortisol measures differentially in jet-lagged and control animals.
Essentially identical glucose signals were observed even after prolonged exposure to blood samples for over 12 days.
