    Identifying Brand Consistency by Product Differentiation Using CNN

    Hung-Hsiang Wang1, Chih-Ping Chen2,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.140, No.1, pp. 685-709, 2024, DOI:10.32604/cmes.2024.047630

    Abstract This paper presents a new method of using a convolutional neural network (CNN) in machine learning to identify brand consistency by product appearance variation. In Experiment 1, we collected fifty mouse devices from the past thirty-five years from a renowned company to build a dataset consisting of product pictures with pre-defined design features of their appearance and functions. Results show that it is a challenge to distinguish periods for the subtle evolution of the mouse devices with such traditional methods as time series analysis and principal component analysis (PCA). In Experiment 2, we applied deep… More >

    Abstract Mesenchymal stem cells (MSCs) are ideal candidates for treating many cardiovascular diseases. MSCs can modify the internal cardiac microenvironment to facilitate their immunomodulatory and differentiation abilities, which are essential to restore heart function. MSCs can be easily isolated from different sources, including bone marrow, adipose tissues, umbilical cord, and dental pulp. MSCs from various sources differ in their regenerative and therapeutic abilities for cardiovascular disorders. In this review, we will summarize the therapeutic potential of each MSC source for heart diseases and highlight the possible molecular mechanisms of each source to restore cardiac function. More >

    Overexpression of RUNX1 mitigates dexamethasone-induced impairment of osteogenic differentiation and oxidative stress injury in bone marrow mesenchymal stem cells by promoting alpha-2 macroglobulin transcription

    QINGJIAN HE1, HUIXIN ZHU2,3, SHANHONG FANG4,5,*

    BIOCELL, Vol.48, No.2, pp. 205-216, 2024, DOI:10.32604/biocell.2023.045109

    Abstract Introduction: Dexamethasone (Dex) caused impaired osteoblast differentiation and oxidative stress (OS) in bone marrow mesenchymal stem cells (BMSCs). This work sought to elucidate the precise molecular pathway through which Dex influences osteogenic differentiation (OD) and OS in BMSCs. Methods: The expression of Runt-related transcription factor 1 (RUNX1) and alpha-2 macroglobulin (A2M) was assessed in Dex-treated BMSCs using qRT-PCR and Western Blot. Following the functional rescue experiments, cell proliferation was determined by MTT assay, reactive oxygen species (ROS) expression by DCFH-DA fluorescent probe, lactate dehydrogenase (LDH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (Gpx) expression… More >

    An overview of autophagy in the differentiation of dental stem cells

    XITONG ZHAO, TIANJUAN JU, XINWEI LI, CHANGFENG LIU, LULU WANG*, LI-AN WU*

    BIOCELL, Vol.48, No.1, pp. 47-64, 2024, DOI:10.32604/biocell.2023.045591

    Abstract Dental stem cells (DSCs) have attracted significant interest as autologous stem cells since they are easily accessible and give a minimal immune response. These properties and their ability to both maintain self-renewal and undergo multi-lineage differentiation establish them as key players in regenerative medicine. While many regulatory factors determine the differentiation trajectory of DSCs, prior research has predominantly been based on genetic, epigenetic, and molecular aspects. Recent evidence suggests that DSC differentiation can also be influenced by autophagy, a highly conserved cellular process responsible for maintaining cellular and tissue homeostasis under various stress conditions.

    Xiandang Shen1,2,3, Runxi He2,3, Xin Li3, Zhuogong Shi2,3,*, Jinfang Meng2,3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.12, pp. 3251-3266, 2023, DOI:10.32604/phyton.2023.042735

    Abstract In this study, newly sprouted shoots of Zanthoxylum armatum (Z. armatum), which were collected after the harvesting period, were used as the primary experimental specimens. A randomized block design and paraffin sectioning method were used to investigate the flower bud differentiation process and the quantity and vitality of buds. Furthermore, the study examined the response of flowering and fruiting to cultivation methods for shoot growth, including layering and plant growth regulator application. The results showed that (a) layering and application of plant growth regulators for Z. armatum accelerated the process of flower bud differentiation by approximately 20 days… More >

    Abstract Introduction: Allergen-specific CD4+ T cells play a central role in autoimmune disorders, allergies and asthma, with Th2-type immunity being the typical functional response of CD4+ T cells. This study aimed to investigate the role of MBD2 in regulating Th2 cell differentiation. Methods: Splenic mononuclear cells were extracted from C57BL/6 mice, and CD4+ T cells were isolated using magnetic beads and confirmed through flow cytometry. Lentivirus was employed to construct MBD2-silenced CD4+ T cells. In vitro experiments were performed to treat splenogenic mononuclear cells and CD4+ T cells with Ovalbumin (OVA), and Th2 cell ratios and IL-4 levels were assessed… More >

    BIOCELL, Vol.47, No.9, pp. 2115-2123, 2023, DOI:10.32604/biocell.2023.030364

    Abstract Background: The regulatory genes related to lipid metabolism affect the intramuscular fat (IMF) content and improve meat quality traits. Mediator Complex Subunit 4 (MED4), a vitamin D receptor protein, affects vitamin D, livestock growth, carcass traits, and triglyceride deposition. However, the physiological function of the MED4 gene on bovine adipocyte differentiation remains unknown. Methods: This study explored the function of the MED4 gene in preadipocyte differentiation in Chinese Red Steppe cattle. The overexpression plasmid and the interference sequences of the MED4 gene were constructed to detect the effects of the MED4 gene on adipogenesis and biomakers using More >

    A novel mutation in ROR2 led to the loss of function of ROR2 and inhibited the osteogenic differentiation capability of bone marrow mesenchymal stem cells (BMSCs)

    WENQI CHEN1,#, XIAOYANG CHU2,#, YANG ZENG3,#, YOUSHENG YAN4, YIPENG WANG4, DONGLAN SUN1, DONGLIANG ZHANG5, JING ZHANG1,*, KAI YANG4,*

    BIOCELL, Vol.47, No.7, pp. 1561-1569, 2023, DOI:10.32604/biocell.2023.028851

    Abstract Background: Receptor tyrosine kinase-like orphan receptor 2 (ROR2) has a vital role in osteogenesis. However, the mechanism underlying the regulation of ROR2 in osteogenic differentiation is still poorly comprehended. A previous study by our research group showed that a novel compound heterozygous ROR2 variation accounted for the autosomal recessive Robinow syndrome (ARRS). This study attempted to explore the impact of the ROR2: c.904C>T variant specifically on the osteogenic differentiation of BMSCs. Methods: Coimmunoprecipitation (CoIP)-western blotting was carried out to identify the interaction between ROR2 and Wnt5a. Double-immunofluorescence staining was used for determining the expressions and co-localization… More > Graphic Abstract

    Oncology Research, Vol.31, No.3, pp. 275-286, 2023, DOI:10.32604/or.2023.028227

    Abstract Background: Lung cancer is one of the most lethal cancers worldwide, but studies have shown that the higher the expression of programmed cell death protein 1 ligand 1 (PD-L1) in non-small cell lung cancer (NSCLC), the more likely it will benefit from anti-PD-L1 immunotherapy. The purpose of our study was to collect and analyze abundant clinical samples in order to provide evidence for clinicians and patients who might consider anti-PD-L1 immunotherapy while jointly formulating treatment plans. Methods: On the one hand, we obtained cases from The Cancer Genome Atlas (TCGA) database, including 498 lung squamous… More >

    Abstract Background: Cardiomyocytes derived from human embryonic stem cells (hESCs) are regulated by complex and stringent gene networks during differentiation. Long non-coding RNAs (lncRNAs) exert critical epigenetic regulatory functions in multiple differentiation processes. However, the involvement of lncRNAs in the differentiation of hESCs into cardiomyocytes has not yet been fully elucidated. Here, we identified the key roles of ZFAS1 (lncRNA zinc finger antisense 1) in the differentiation of cardiomyocytes from hESCs. Methods: A model of cardiomyocyte differentiation from stem cells was established using the monolayer differentiation method, and the number of beating hESCs-derived cardiomyocytes was calculated. Gene expression… More >
