The high-glucose cultures had focal 'hot spots' of greater DCF fluorescence intensities (quantified by thresholding the highest 2% fluorescence values; see the Materials and methods section) that averaged approximately twice those of the overall mean intensities in the high-glucose cultures (thresholded at 30%) at all time points.
The approach should be replicated in studies on other populations and cultures, as thresholds for reporting symptoms during midlife may differ.
We discuss the use of quantitative cultures and thresholds to differentiate between colonization and infection in pneumonia patients; we also consider the inaccuracy of diagnostic studies, which compromises the reproducibility of these data in clinical practice.
These provincial manufacturers, professional men and gifted amateurs were edging society and culture towards the threshold of the modern and away from old patterns and customs.
Ritual vessels, oracle bones (used by shamans in divination), ceremonial jade objects and ornaments, and architecture (pounded-earth foundations, protective city walls, rectilinear organization) reflect an advanced material culture on the threshold of the Bronze Age.
Cultures were considered positive if they yielded organisms on final culture with a threshold value ≥103 cfu mL−1.
This view of dissidence has nothing surprising about it conformity reigned in Soviet consciousness; a public intolerance of non-conformist behavior always penetrated Soviet culture; and the threshold for deviance from custom was similarly low.
We defined positive bacteria culture on a threshold of ≥104 cfu/ml based on previous studies [ 17].
Then, the result was compared to the quantitative culture with a threshold at 104 colony-forming units per milliliter for bronchoalveolar lavage and 103 colony-forming units per milliliter for minibronchoalveolar lavage.
Of the 37 non treated patients (11%), 6 patients (16%) would finally be diagnosed with cystitis according to urine culture at standard thresholds and 7 (19%) at reduced thresholds.
