    Comparative Assessment of Environmental DNA and Bulk-Sample Metabarcoding in Biosecurity Surveillance for Detecting Biting Midges (Ceratopogonidae) by Jieyun Wu, Dongmei Li, Rebijith K. Balan, Sherly George, Lora Peacock, Chandan Pal

    Published 2025-05-01
    “…Two Cytochrome oxidase I (COI) barcoding primer sets were employed to study biodiversity and detect exotic species. The results indicated that DNA metabarcoding with homogenized insect bulk samples had a higher overall detection accuracy rate (over 81% for both primer pairs) compared to ethanol fluid-derived eDNA samples from traps (68.42% and 55.26% for the primer sets LCO1490/HCO2198 and mlCOIintF/jgHCO2198, respectively) based on congruence with morphological identification. …”

    Detection of fusion events by RNA sequencing in FFPE versus freshly frozen colorectal cancer tissue samples by Maxim Sorokin, Maxim Sorokin, Maxim Sorokin, Maxim Sorokin, Vladimir Lyadov, Vladimir Lyadov, Vladimir Lyadov, Maria Suntsova, Marat Garipov, Anna Semenova, Natalia Popova, Egor Guguchkin, Rustam Heydarov, Marianna Zolotovskaia, Xiaowen Zhao, Qing Yan, Ye Wang, Evgeny Karpulevich, Anton Buzdin, Anton Buzdin, Anton Buzdin, Anton Buzdin

    Published 2025-01-01
    “…However, tumor biosamples are usually formalin-fixed paraffin-embedded (FFPE) tissue blocks where RNA is heavily degraded, which in theory may result in decreased efficiency of fusion detection. Here, for the first time, we compared the efficacy of gene fusion detection by RNAseq for matched pairs of freshly frozen in RNA stabilizing solution (FF) and FFPE tumor tissue samples obtained from 29 human colorectal cancer patients. …”
