    BIOCELL, Vol.49, No.12, pp. 2245-2282, 2025, DOI:10.32604/biocell.2025.071830 - 24 December 2025

    Abstract Neurodegenerative diseases (NDs) such as Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD), and amyotrophic lateral sclerosis (ALS) are characterized by progressive neuronal loss, which is closely linked to mitochondrial dysfunction. These pathologies involve a complex interplay of genetics, protein misfolding, and cellular stress, culminating in impaired energy metabolism, an increase in reactive oxygen species (ROS), and defective mitochondrial quality control. The accumulation of damaged mitochondria and dysregulation of pathways such as the Integrated Stress Response (ISR) are central to the pathogenesis of these conditions. This review explores the critical relationship between mitochondrial stress… More >

    Over Temperature of the Thermal Barrier Coating System with Local Spallation

    Fan Sun1,2, Yiwen Chen2,3, Dingjun Li3, Rong Xu2, Peng Jiang2, Tiejun Wang2, Lei Yang1,2,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.33, No.1, pp. 1-1, 2025, DOI:10.32604/icces.2025.012370

    Abstract The capacity to maintain operational temperatures within safe thresholds is paramount for the longevity of thermal barrier coating systems (TBCs). Nonetheless, TBC spallation during service can lead to localized over temperature, which may result in catastrophic failure. In this study, we examine the phenomenon of over temperature in locally spalled TBCs through a combination of numerical simulations and experimental investigations. We perform numerical calculations to determine the temperature distributions in locally spalled TBCs with varying spallation depths and diameters, and we analyze the correlation between the maximum temperature within the spalled regions and the dimensions… More >

    Butyrophilin Downregulation in Chronic Lymphocytic Leukaemia: An Important Barrier to γδ T Cell-Mediated Cytotoxicity

    Natalia Lehman, Agnieszka Bojarska-Junak, Michał Zarobkiewicz*

    BIOCELL, Vol.49, No.6, pp. 1085-1099, 2025, DOI:10.32604/biocell.2025.063960 - 24 June 2025

    Abstract Introduction: Butyrophilins (BTNs) belong to the immunoglobulin superfamily; they play crucial roles in immune regulation, especially in γδ T cell activation. While their expression has been studied in solid tumours, their involvement in hematologic malignancies remains poorly understood. Objectives: We hypothesised that BTNs are dysregulated in chronic lymphocytic leukaemia (CLL), contributing to γδ T cell dysfunction and potentially influencing disease progression. Methods: In this study, we analyzed publicly available microarray and RNA-seq datasets to investigate the expression patterns of BTN genes in CLL. Results: Our findings reveal significant dysregulation of BTN gene expression in CLL, with BTN2A1, BTN3A1, BTN3A2,… More >

    Journal of Renewable Materials, Vol.13, No.6, pp. 1209-1227, 2025, DOI:10.32604/jrm.2025.02024-0068 - 23 June 2025

    Abstract Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract
