Introduction:In order to detect Trypanosoma cruzi and determine the genetic profiles of the parasite during the chronic phase of Chagas disease (ChD), parasitological and molecular diagnostic methods were used to assess the blood of 91 patients without specific prior treatment. Methods: Blood samples were collected from 68 patients with cardiac ChD and 23 patients with an indeterminate form of ChD, followed by evaluation using blood culture and polymerase chain reaction. T. cruzi isolates were genotyped using three different genetic markers. Results: Blood culture was positive in 54.9% of all patients, among which 60.3% had the cardiac form of ChD, and 39.1% the indeterminate form of ChD. There were no significant differences in blood culture positivity among patients with cardiac and indeterminate forms. Additionally, patient age and clinical forms did not influence blood culture results. Polymerase chain reaction (PCR) was positive in 98.9% of patients, although comparisons between blood culture and PCR results showed that the two techniques did not agree. Forty-two T. cruzi stocks were isolated, and TcII was detected in 95.2% of isolates. Additionally, one isolate corresponded to TcIII or TcIV, and another corresponded to TcV or TcVI. Conclusions: Blood culture and PCR were both effective for identifying T. cruzi using a single blood sample, and their association did not improve parasite detection. However, we were not able to establish an association between the clinical form of ChD and the genetic profile of the parasite.

“…Allelic richness (A) is a measure of allele number that minimizes the effect of sample size, as described by El Mousadik & Petit (1996). We grouped isolates by block and used a KruskaleWallis test (Hollander et al 2013) under the R stats package to explore potential differences between the A values for blocks as grouped by planting generation, by plantation, and by region. We also tested for a possible link between isolate allelic richness and oil palm genetic background (data available only for Sumatra) by taking groups of isolates from blocks where all the oil palms had the same genetic background (SI Table 1) and performing a KruskaleWallis test on the A values obtained from those groups.…”

“…Thus, we proceeded to post-hoc analyses. The Wilcoxon-Nemenyi-McDonaldThompson test was developed specifically for a post-hoc test that enables pairwise comparisons for non-parametric repeated measures data [36]. In Table 1, we presented the results of descriptive analyses and the pairwise comparisons between the top three and bottom three mood boards for both two commercials.…”

Abstract.Emotion is an essential part of user experience. While researchers are striving for new research tools for evaluate emotional experiences in design, designers have been using experience-based tools for studying emotions in practice, such as mood boards. Mood boards were developed for communicating emotional qualities between designers and clients, but have not yet been considered as an evaluation tool for investigating emotional experience. In t his study we examined whether design students and non-design students have similar criteria in evaluating these mood boards. The results showed that the inter-rater reliability among all participants were considerably high, which suggested that mood boards are potential to be used as an evaluation tool for research on emotion.
