    RETRACTED ARTICLE: LRPPRC regulates malignant behaviors, protects mitochondrial homeostasis, mitochondrial function in osteosarcoma and derived cancer stem-like cells by Ziyi Zhao, Yingwei Sun, Jing Tang, Yuting Yang, Xiaochao Xu

    Published 2023-10-01
    “…Results we found that LRPPRC was highly expressed in several osteosarcoma cell lines and that LRPPRC knockdown inhibited malignant behaviors, including proliferation, invasion, colony formation and tumor formation, in MG63 and U2OS cells. Enriched CSCs derived from MG63 and U2OS cells presented upregulated LRPPRC levels compared to parental cells (PCs), and LRPPRC knockdown markedly decreased the sphere-forming capacity. …”

    A blind navigation guide model for obstacle avoidance using distance vision estimation based YOLO-V8n by EBERE CHIDI, Edward Anoliefo, Collins Udanor, Asogwa Tochukwu Chijindu, Lois Onyejere Nwobodo

    Published 2025-02-01
    “…Furthermore, the issue of bounding box overlap in the model was addressed by applying a Wise Intersection over Unit (WIoU) loss function. Collectively, these formulated the new transfer learning algorithm called YOLO-V8n+WFE+Bi-FPN+DVE+WIoU used in this work for high-level obstacle detection and distance estimation. …”

    Wheat flour as carbon source on water quality, growth performance, hemolymph biochemical and immune parameters of Pacific white shrimp (Penaeus vannamei) juveniles in biofloc techn... by Mohammad Hossein Khanjani, Jamshid Eslami, Maurício Gustavo Coelho Emerenciano

    Published 2025-03-01
    “…The control group exhibited the lowest levels of lysozyme (19 u/mL/min) and phenoloxidase (0.41 u/mL). The results demonstrated that by adding wheat flour to the biofloc cultivation system (under the conditions of this study) in the amount of 50–75 % of the daily feed ration, the water quality, growth performance, feed efficiency, survival rate, hemolymph biochemical, and immunity activities of P. vannamei improved.…”

    Published 2024-12-01
    “…Our proposed Body Packs Detection (BPD) model achieved a mean average precision (mAP) value of 86.6% when the intersection over union (IoU) was 0.5, and a mAP value of 45.6% at different IoU thresholds (from 0.5 to 0.95 in steps of 0.05). …”
