P2Y12 Inhibitor Monotherapy Combined With Colchicine Following PCI in ACS Patients: The MACT Pilot Study

© 2023 by the American College of Cardiology Foundation. Published by Elsevier. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1016/j.jcin.2023.05.035This proof-of-concept pilot trial investigated the feasibility of ticagrelor or prasugrel P2Y12 inhibitor monotherapy combined with colchicine immediately after PCI in ACS patients. The day after PCI, aspirin was replaced with low-dose colchicine (0.6 mg daily) on ticagrelor or prasugrel maintenance. Among 200 ACS patients enrolled, stent thrombosis occurred in two patients for 3 months. High platelet reactivity assessed by VerifyNow assay was low at discharge and hs-CRP levels decreased significantly within 1 month after PCI. Accordingly, P2Y12 inhibitor mono antiplatelet and colchicine therapy is feasible in ACS patients undergoing PCI and associated with favorable platelet function and inflammatory profiles.Peer reviewe

Complete Chloroplast Genome Sequences and Comparative Analysis of Chenopodium quinoa and C. album

The Chenopodium genus comprises ~150 species, including Chenopodium quinoa and Chenopodium album, two important crops with high nutritional value. To elucidate the phylogenetic relationship between the two species, the complete chloroplast (cp) genomes of these species were obtained by next generation sequencing. We performed comparative analysis of the sequences and, using InDel markers, inferred phylogeny and genetic diversity of the Chenopodium genus. The cp genome is 152,099 bp (C. quinoa) and 152,167 bp (C. album) long. In total, 119 genes (78 protein-coding, 37 tRNA, and 4 rRNA) were identified. We found 14 (C. quinoa) and 15 (C. album) tandem repeats (TRs); 14 TRs were present in both species and C. album and C. quinoa each had one species-specific TR. The trnI-GAU intron sequences contained one (C. quinoa) or two (C. album) copies of TRs (66 bp); the InDel marker was designed based on the copy number variation in TRs. Using the InDel markers, we detected this variation in the TR copy number in four species, Chenopodium hybridum, Chenopodium pumilio, Chenopodium ficifolium, and Chenopodium koraiense, but not in Chenopodium glaucum. A comparison of coding and non-coding regions between C. quinoa and C. album revealed divergent sites. Nucleotide diversity >0.025 was found in 17 regions—14 were located in the large single copy region (LSC), one in the inverted repeats, and two in the small single copy region (SSC). A phylogenetic analysis based on 59 protein-coding genes from 25 taxa resolved Chenopodioideae monophyletic and sister to Betoideae. The complete plastid genome sequences and molecular markers based on divergence hotspot regions in the two Chenopodium taxa will help to resolve the phylogenetic relationships of Chenopodium
