    “…Ralston et al highlight the ways that different actors in global nutrition governance conceptualise and frame the role of non-state actors in governance arrangements, including the potential for conflict of interest (COI) to undermine global health efforts. The authors argue that the World Health Organization (WHO) draft tool on managing COI in nutrition policy is an important innovation in global health, but that further research and refinement is needed for operationalising the management of COI with diverse actors in diverse contexts. …”

    “…The purpose of this study is to develop a method to screen for nuclear mitochondrial DNA segments (nuMTs) in large COI datasets. We do this by: (1) describing gene and nuMT characteristics from an artificial COI barcode dataset, (2) show the impact of two different pseudogene removal methods on perturbed community datasets with simulated nuMTs, and (3) incorporate a pseudogene filtering step in a bioinformatic pipeline that can be used to process Illumina paired-end COI metabarcode sequences. …”

    “…RESULTS: The sequences generated 169 COI haplotypes and 90 ITS alleles. A higher haplotype/allele diversity (h = 0.9909 for the COI gene and Ad = 0.8193 for the ITS region) compared to a low nucleotide diversity (π = 0.020605 for COI gene and π = 0.013667 for the ITS region), present for a high number of singleton and private haplotypes/alleles imply population expansion in the past. …”

    “…Indeed, all attempts to develop universal flatworm-specific COI markers have failed so far. We demonstrate how high molecular variability and contamination problems limit the possibilities for barcoding using standard COI-based protocols in flatworms. …”
