However, relatively little is known about the individual impact of each of these different variables on the usefulness of samples for molecular applications, such as PCR.
A second suggestion is that in an attempt to preserve the usefulness of samples, researchers could provide participants with withdrawal options.
This work also emphasizes the usefulness of higher sampling rates, even for the measurement of signals that are inherently slow, and has important implications for the development of NIRS based BCIs, and neurofeedback techniques.
To assess the usefulness of our sampling strategy and its implementation in the context of real genetic data, we address the problem of inferring global dynamics of influenza epidemics from genetic data.
A further problem with anonymised samples is that it can limit the usefulness of the sample.
To determine the usefulness of such samples for molecular analysis, real-time RT-PCR was performed on the RNA samples.
In addition, automation does not inform the quality of the specimen to help research personnel determine the usefulness of the sample nor does it provide a process for correcting and identifying errors that have occurred during previous sample collections.
But by early January, Dr. Shaler received confirmation that the chaotic nature of the collection process in the first days had created doubt about the usefulness of the samples.
Objective: We studied the usefulness of self-sampling in cervical cancer prevention.
As an alternative specimen, we evaluated the diagnostic usefulness of saliva samples with rapid influenza diagnostic tests (RIDTs).
