Most strikingly, expression of type 1 fimbrial genes, which are among the most highly expressed genes during murine experimental UTI and encode an essential virulence factor for this experimental model, was undetectable in six of the eight E. coli strains from women with UTI.
High- versus low-FPG group differences were identified using a mixture model to jointly consider detectable metabolite levels and frequency of undetectable levels.
No concentration response relationship was found with treatment (maraviroc vs. placebo) and presence/absence of undetectable maraviroc concentration (adherence marker) in the model.
PROC LIFEREG was used for left-censored regression (tobit) modelling to obtain an accurate estimate of the mean exposure level accounting for the large proportion of undetectable values.
Ultimately, the results of this Round Robin cannot solve the dispute between toxicokinetic models predicting undetectable levels of uBPA in human blood and biomonitoring studies reporting measurable levels of uBPA (in the low or sub ng/ml range).
MMP activation and delivery of this formulation to breast cancer cells expressing the FA receptor achieved greater than 50% protein-level knockdown of a model gene with undetectable cytotoxicity.
Then, the boundary of undetectable region is determined.
No significant association was observed with rates of undetectable viral loads.
Meshed areas indicate zones of undetectable lightning discharges with absolute peak currents below 10 kA.
Is this photographic evidence, or a bit of undetectable computer graphics fiction? .
