Finally, given HIV's extraordinary evolutionary rates and the inherent difficulties in obtaining samples at the time of transmission, we investigated the relationship between sampling time and virologic compartmentalization using five distinct algorithms.
To permit that assessors with a low degree of training quantitatively evaluate samples consistently, this method proposes the presentation of reference materials ("weak" and "strong") together with all set of samples at the time of evaluation.
Parathyroid hormone (PTH) levels were measured preoperatively before draping, followed by further samples at the time of extirpation and 10 min thereafter.
It is therefore important that when analysing for acrylamide in STPs researchers take into account the age of the samples at the time of analysis.
On the other hand, the sludge that did not have any parasites was in much drier condition and less smelly (compared to the other two ecosan samples) at the time of sampling.
The survey was conducted in two parts, with an initial sampling of 70 STPs from the United States and Sweden in 2008 [13], and a second sampling of 73 STPs in 2010 [14], conducted in order to ensure that the ages of the samples at the time of analysis were reflective of consumption patterns.
As the i.v. virus application resulted in a very rapid disease progression, only blood samples at the time of death could be analyzed.
To minimize the amount of circulating AAV library particles in our tissue samples at the time point of harvest, we analyzed the kinetics of circulating AAV library particles.
The relationship between the cellular HIV-1 DNA loads measured in this study and other clinical parameters and characteristics of the samples at the time of sampling were also investigated.
Pfdhfr mutations at positions 51, 59, 108 and a Pfdhps mutation at position 437 were detected in almost all parasite-positive samples at the time of the December survey (Table 3).
Participants provided blood samples at the time they returned their self-administered questionnaire.
