The records state that blood samples screened using the ELISA test came back as "negative" for HIV antigens.
Samples screened as having THC concentrations ≥4 ng/ml were further tested using liquid/gas chromatography and mass spectrometry (LC/MS/MS) technology with a minimum detectable THC concentration of 2 ng/ml in oral fluid.
These organisms were detected across the samples screened with Staphylococcus species and Escherichia coli isolated in five out of the six samples examined, Klebsiella and Proteus in four samples, Pseudomonas in two samples while Salmonella was detected in only one sample.
Of the samples screened for blood cotinine concentration (n = 3; Fig. 1), none was detected during PLA whereas cotinine concentration increased as a function of dose (NIC-2: 20 ± 21 ng mL−1, NIC-4: 87 ± 8 ng mL−1; trial: p = 0.01, η p 2 = 0.97).
Of the 245 blood samples screened, 78 samples tested positive (31% prevalence) for T. pestanai.
From a total of 167 blood samples screened for parasite growth and recovery only 101 were used for adhesion studies.
Mutation frequency equals the size of the amplicon multiplied by the total number of samples screened and divided by the total number of identified mutants.
This corresponds to 10% of the samples screened, consistent with previous observations and providing further insight to sporadic presence of MCPyV in skin of healthy individuals [14], [18].
We found no Attamyces diversity within each of the six A. cephalotes nests (an average of 73 Attamyces samples screened per nest, collected from at least three quadrants of each nest, 3 12 gardens for each quadrant, three fragments sampled per garden), except for five putative mutant Attamyces strains in five different gardens (Supporting Information Table S3).
Whilst the number of hair samples screened and positives samples confirmed are considerably higher than what is typically used in publications focusing on the chemical analyses for steroids [47], [48], it is somewhat below the typical sample size in similar experimental psychology studies [45].
There were 138 samples screened for H63D and 190 samples screened for C282Y.
