In order to explore whether the [18F]FDG-6-P was being dephosphorylated to produce [18F]FDG during systemic circulation, samples of mouse blood were collected and incubated with either [18F]FDG or [18F]FDG-6-P ex vivo for 1 h.
Following death, the circulation stops and tryptase is no longer removed from the circulation; samples taken postmortem are helpful in evaluating whether the terminal events were related to anaphylaxis.
To assess the clearance and half-life of I-hDFM in the circulation samples of patient's urine and whole blood (in 2 ml heparinised tubes) were collected at each scanning time.
The expression of miR-200c and miR-141 was measured in collected cancerous tissues in the majority of studies except seven targeted in circulation samples [ 23– 27, 29, 29, 37, 39], including one researched in cancerous tissues and blood samples meanwhile [ 29].
Sampling from the vessels was done every two days, and tests were made for measurement of total alkalinity, ammonia, ammonium ion, suspended solids, COD, nitrogen dioxide and acidity, in which after 30 days from the first circulation, the samples were found to be without ammonia or its derivatives.
To determine whether steroid treatments resulted in increased concentrations in the circulation, serum samples from vehicle (control) and hormone-injected mice were analyzed for 5αP and 3αHP at 15 to 22 days and 42 days after the last treatment.
For example, Jackson (2007) performed content analysis of advertisements from national and local newspapers with a high circulation, and the sample was chosen to be representative of the range of occupations in the occupational sectors.
In the reduced and intermediate stages of oxidation, the pH was adjusted inside an anaerobic glove chamber with argon circulation to avoid sample reoxidation.
At each time point, a cuff was inflated at the wrist of the exercising forearm to minimise the contribution of the cutaneous circulation to the sample [ 29].
