RESUMEN
BACKGROUND: Organizational characteristics and attributes are critical issues to consider when implementing and evaluating workplace training. This study was a qualitative examination of the organizational context as it pertained to the implementation of a workplace mental health program called Road to Mental Readiness (R2MR) in police organizations in Canada. METHODS: We conducted a qualitative key informant study in 9 different policing organizations in Canada. RESULTS: The central theme of "successful cultural uptake" emerged as key to R2MR's implementation and the ability to facilitate broader culture change. Successful cultural uptake was enabled by several contextual factors, including organizational readiness, strong leadership support, ensuring good group dynamics, credibility of the trainers, implementing widely and thoroughly, and implementing R2MR as one piece of a larger puzzle. Successful cultural uptake was also described as enabling R2MR's impact for broader cultural change within the organization. This enablement occurred through enhanced dialogue about mental health and the introduction of a common language, a supportive workplace culture, increased help seeking, and organizational momentum for additional mental health programming and policy initiatives. CONCLUSION: Successful uptake of R2MR has the potential to lead to promote change within policing organizations. The model derived from our research may function as a tool or roadmap to help guide other organizations in the process of or planning to implement R2MR or a similar intervention.

A number of technologies are available to increase the abundance of DNA markers and contribute to developing high resolution genetic maps suitable for genetic analysis. The aim of this study was to expand the number of Diversity Array Technology (DArT) markers on the wheat array that can be mapped in the wheat genome, and to determine their chromosomal location with respect to simple sequence repeat (SSR) markers and their position on the cytogenetic map. A total of 749 and 512 individual DArT and SSR markers, respectively, were identified on at least one of four genetic maps derived from recombinant inbred line (RIL) or doubled haploid (DH) populations. A number of clustered DArT markers were observed in each genetic map, in which 20-34% of markers were redundant. Segregation distortion of DArT and SSR markers was also observed in each mapping population. Only 14% of markers on the Version 2.0 wheat array were assigned to chromosomal bins by deletion mapping using aneuploid lines. In this regard, methylation effects need to be considered when applying DArT marker in genetic mapping. However, deletion mapping of DArT markers provides a reference to align genetic and cytogenetic maps and estimate the coverage of DNA markers across the wheat genome.

BACKGROUND: Previous studies showed that Mirasol (Navigant Biotechnologies, Inc.) pathogen reduction technology (PRT) treatment resulted in an increase in platelet (PLT) glucose consumption and lactate production rates and decrease in pH in media during PLT storage. Increased glycolytic flux could result from damage to mitochondria and/or increased ATP consumption. STUDY DESIGN AND METHODS: PLT concentrates were collected by standard automated blood component collection system (Trima, Gambro BCT) procedure on Day 0 and treated with Mirasol PRT treatment on Day 1. PLT mitochondrial transmembrane potential was evaluated by staining PLTs with JC-1 followed by flow cytometry analysis. Mitochondrial enzymatic activity was measured by the MTT assay. ATP content and pH were also quantified. The values for these measurements were compared among control, untreated, and pathogen reduction technology (PRT)-treated PLTs during PLT storage for up to 7 days. RESULTS: No significant changes were found in pH, JC-1 signal, MTT activity, and ATP content of the PLTs immediately after PRT treatment. The treated PLTs exhibited a moderate but significantly accelerated decrease in pH and lower ATP content after 7-day storage when compared to control PLTs. Neither the JC-1 assay nor the MTT assay, however, showed a significant difference between control and treated PLTs during PLT storage. CONCLUSIONS: There is no evidence from these studies that Mirasol PRT treatment alters PLT mitochondrial structural and functional integrity immediately after treatment and during PLT storage. An increased demand for ATP may be the driving force for observed increases in both the glycolytic flux and the oxidative metabolism observed in treated PLTs.
