    Learning-Based Prediction of Soft-Tissue Motion for Latency Compensation in Teleoperation

    Guangyu Xu1,2, Yuxin Liu1, Bo Yang1, Siyu Lu3,*, Chao Liu4, Junmin Lyu5, Wenfeng Zheng1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.074938 - 29 January 2026

    Abstract Soft-tissue motion introduces significant challenges in robotic teleoperation, especially in medical scenarios where precise target tracking is critical. Latency across sensing, computation, and actuation chains leads to degraded tracking performance, particularly around high-acceleration segments and trajectory inflection points. This study investigates machine learning-based predictive compensation for latency mitigation in soft-tissue tracking. Three models—autoregressive (AR), long short-term memory (LSTM), and temporal convolutional network (TCN)—were implemented and evaluated on both synthetic and real datasets. By aligning the prediction horizon with the end-to-end system delay, we demonstrate that prediction-based compensation significantly reduces tracking errors. Among the models, TCN More >

    The Crucial Role of NAD+ in Mitochondrial Metabolic Regulation

    Kumudesh Mishra1,2,*, Or Kakhlon1,2

    BIOCELL, Vol.49, No.7, pp. 1101-1123, 2025, DOI:10.32604/biocell.2025.061725 - 25 July 2025

    Abstract Mitochondria are central organelles in cellular metabolism, orchestrating energy production, biosynthetic pathways, and signaling networks. Nicotinamide adenine dinucleotide (NAD+) and its reduced form (NADH) are essential for mitochondrial metabolism, functioning both as redox coenzymes and as signaling agents that help regulate cellular balance. Thus, while its major role is in energy production, NAD+ is widely recognized as a metabolic cofactor and also serves as a substrate for various enzymes involved in cellular signaling, like sirtuins (SIRTs), poly (ADP-ribosyl) polymerases (PARPs), mono (ADP-ribosyl) transferases, and CD38. Sirtuins, a family of NAD+-dependent deacetylases, are critical in this regulatory network.… More >

    Abstract Background: Ovarian cancer (OC) is a representative malignancy of the female reproductive system, with a poor prognosis. Long non-coding RNAs (lncRNAs) crucially affect tumor development. This study aimed to identify lncRNAs that potentially participated in OC. Methods: LncRNA expression in cells and tissues was quantified using reverse transcription-quantitative PCR, while fluorescence in situ hybridization determined their cellular localization. Various in vitro assays, together with a mouse xenograft model, were employed to elucidate the function of CYMP antisense RNA 1 (CYMP-AS1) in OC. The molecular mechanisms underlying CYMP-AS1 regulation were investigated through RNA pull-down and immunoprecipitation assays, immunofluorescence… More > Graphic Abstract

    Abstract Objectives: While programmed cell death 1 (PD-1) inhibitors have improved cancer treatment, the function and mechanisms of programmed cell death ligand 1 (PD-L1), particularly when expressed by cancer cells, remain unclear. This study aims to explore the role of PD-L1 within breast cancer cells and identify key targets for future immunotherapy. Methods: RNA-seq was performed on breast cancer cells with silenced PD-L1 to screen for differentially expressed genes, followed by bioinformatics analysis. Clinical specimens from breast cancer patients undergoing primary surgery without preoperative treatment were collected, along with in vitro analysis to validate the potential mechanism.

    Mechanistic Insights into N-Oleoylethanolamide-Mediated Hepatoprotection via PPAR-α

    Darya Ivashkevich, Arina Ponomarenko*, Igor Manzhulo, Inessa Dyuizen

    BIOCELL, Vol.49, No.4, pp. 607-627, 2025, DOI:10.32604/biocell.2025.061606 - 30 April 2025

    Abstract The high prevalence of obesity and associated nonalcoholic fatty liver disease (NAFLD) in the population determines the increased interest in identifying molecular targets for regulating the processes underlying these pathologies. The search for new endogenous bioregulators of lipid metabolism and their inclusion in therapeutic regimens for the treatment of patients is becoming a potentially promising direction in science and medicine. Oleoylethanolamide (OEA) is an endogenous lipid mediator capable of exerting multiple hypolipidemic, anti-inflammatory, and hepatoprotective effects mediated by agonism with receptors of the peroxisome proliferator-activated receptor (PPAR) family (PPAR-α and PPAR-γ).

    Gege Liu#, Houfang Zhang#, Yunhui Peng*

    BIOCELL, Vol.49, No.4, pp. 519-538, 2025, DOI:10.32604/biocell.2025.061470 - 30 April 2025

    Abstract Nucleosomes play a vital role in chromatin organization and gene regulation, acting as key hubs that interact with various chromatin-associated factors through diverse binding mechanisms. Recent research has highlighted the prevalence of mutations in linker histones across different types of cancer, emphasizing their critical involvement in cancer progression. These cancer-associated mutations in linker histones have been shown to disrupt nucleosome stacking and the formation of higher-order chromatin structures, which in turn significantly affect epigenetic regulatory processes. In this review, we provide a comprehensive analysis of how cancer-associated linker histone mutations alter their physicochemical properties, influencing More >
