Similarly, surgical specimen analysis was performed in lung lesions in 10 patients [ 4], and anti-3-[F]FACBC uptake in malignant lesions (SUVmax5.9 ± 3.4) was greater than that in inflammatory lesions (SUVmax2.2 ± 0.03) at 28 min (P < 0.05).
Finally, preanalytic factors that account for poor tonometric reproducibility, such as inadequate volume of saline in the tonometer, errors in timing the dwell time of the sample or in the technique used to aspirate the tonometered saline sample, mixing the sample with air from the tonometer dead space, and delays in specimen analysis, might be prevented [ 5].
In our study population, 127 serum samples of travellers with antibody titres indicating probable acute or recent dengue infection in the standard PanBio-ELISA were further analyzed and revealed a high rate (42.5%) of false positive results in single specimen analysis.
A major roadblock to advances in melanoma therapy has been the relative paucity of informative tissue specimens available for analysis in profiling studies as well as the notoriously heterogeneous nature of this malignancy.
To confirm if specimens used for analysis in this study contained a significant amount of tumour cells, typically 50% or more, a neighboring surface was examined histologically with frozen sections.
The following criteria were applied to include breast tumor specimens for final analysis in this study: (1) sufficient frozen tumor material, (2) more than 30% epithelial tumor cell nuclei in haematoxylin/eosin-stained sections, and (3) specimen of good RNA quality according to predefined criteria [ 15].
In a survey of 1033 serum specimens for electrolyte analysis in an acute-care hospital, he and an associate found that 53% of the patients had magnesium levels <0.74 mmol/L, while the ordering physicians suspected and ordered magnesium levels specifically in only 10% of patients.
In analogy to the former original Dukes-System 641 surgical resection specimens permited an analysis in relation to the lymph node-status by the tumour-stage (Stage I to IV) supported by the Union International Contre le Cancer (UICC) and the American Joint Committee on Cancer (AJCC) [ 1- 4, 14].
Colectomy specimens were available for analysis in 64 cases.
The typical FFPE specimens used for expression analysis in this study are shown in Fig. S1.
