    Javaid Ali1, Armando Ciancio2, Kashif Ali Khan3, Nauman Raza4,5, Haci Mehmet Baskonus6,*, Muhammad Luqman1, Zafar-Ullah Khan7

    CMES-Computer Modeling in Engineering & Sciences, Vol.140, No.3, pp. 2275-2296, 2024, DOI:10.32604/cmes.2024.046923

    Abstract This study proposes a structure-preserving evolutionary framework to find a semi-analytical approximate solution for a nonlinear cervical cancer epidemic (CCE) model. The underlying CCE model lacks a closed-form exact solution. Numerical solutions obtained through traditional finite difference schemes do not ensure the preservation of the model’s necessary properties, such as positivity, boundedness, and feasibility. Therefore, the development of structure-preserving semi-analytical approaches is always necessary. This research introduces an intelligently supervised computational paradigm to solve the underlying CCE model’s physical properties by formulating an equivalent unconstrained optimization problem. Singularity-free safe Padé rational functions approximate the mathematical More >

    Rapid and Accurate Identification of Concrete Surface Cracks via a Lightweight & Efficient YOLOv3 Algorithm

    Haoan Gu1, Kai Zhu1, Alfred Strauss2, Yehui Shi3,4, Dragoslav Sumarac5, Maosen Cao1,*

    Structural Durability & Health Monitoring, Vol.18, No.4, pp. 363-380, 2024, DOI:10.32604/sdhm.2024.042388

    Abstract Concrete materials and structures are extensively used in transformation infrastructure and they usually bear cracks during their long-term operation. Detecting cracks using deep-learning algorithms like YOLOv3 (You Only Look Once version 3) is a new trend to pursue intelligent detection of concrete surface cracks. YOLOv3 is a typical deep-learning algorithm used for object detection. Owing to its generality, YOLOv3 lacks specific efficiency and accuracy in identifying concrete surface cracks. An improved algorithm based on YOLOv3, specialized in the rapid and accurate identification of concrete surface cracks is worthy of investigation. This study proposes a tailored… More >

    OPA3 overexpression modulates lipid droplet production and sensitizes colorectal cancer cells to bevacizumab treatment

    HONGBIAO WU*, DONGFANG LIU

    BIOCELL, Vol.48, No.6, pp. 971-980, 2024, DOI:10.32604/biocell.2024.049466

    Abstract Background: Colorectal cancer (CRC) represents a substantial risk to public health. Bevacizumab, the first US FDA-approved antiangiogenic drug (AAD) for human CRC treatment, faces resistance in patients. The role of lipid metabolism, particularly through OPA3-regulated lipid droplet production, in overcoming this resistance is under investigation. Methods: The protein expression pattern of OPA3 in CRC primary/normal tissues was evaluated by bioinformatics analysis. OPA3-overexpressed SW-480 and HCT-116 cell lines were established, and bevacizumab resistance and OPA3 effects on cell malignancy were examined. OPA3 protein/mRNA expression and lipid droplet-related genes were measured with Western blot and qRT-PCR. OPA3… More > Graphic Abstract

    Anexelekto (AXL) Increases Resistance to EGFR-TKI and Activation of AKT and ERK1/2 in Non-Small Cell Lung Cancer Cells

    Yaqiong Tian*1, Zengli Zhang†1, Liyun Miao*, Zhimin Yang, Jie Yang*, Yinhua Wang§, Danwen Qian, Hourong Cai*, Yongsheng Wang*

    Oncology Research, Vol.24, No.5, pp. 295-303, 2016, DOI:10.3727/096504016X14648701447814

    Abstract Recently, epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have revolutionized nonsmall cell lung cancer (NSCLC) treatment. However, resistance remains a major obstacle. Anexelekto (AXL) is a member of receptor tyrosine kinases (RTKs) and shares the same downstream signaling pathways with EGFR, such as PI3K/AKT and MAPK/ERK. AXL overexpression in resistant tumors has been implicated in many previous studies in vitro and in vivo. In this study, we further examined whether expression of AXL and its downstream targets increased in gefitinib-resistant PC9 cells (PC9GR). In addition, we hypothesize that knocking down AXL in PC9GR and… More >

    A Retrospective Comparison of the Clinical Efficacy of Gefitinib, Erlotinib, and Afatinib in Japanese Patients With Non-Small Cell Lung Cancer

    Atsushi Fujiwara*, Masamichi Yoshida*, Hajime Fujimoto, Hiroki Nakahara, Kentaro Ito, Kota Nishihama§, Taro Yasuma§, Osamu Hataji, Osamu Taguchi, Corina N. D’Alessandro-Gabazza§, Esteban C. Gabazza§, Tetsu Kobayashi

    Oncology Research, Vol.26, No.7, pp. 1031-1036, 2018, DOI:10.3727/096504018X15151523767752

    Abstract Tyrosine kinase inhibitors (TKIs) are very effective against non-small cell lung cancer (NSCLC) caused by epidermal growth factor receptor (EGFR) mutation. Before the approval of osimertinib in March 2016, there were only three available EGFR TKIs (gefitinib, erlotinib, and afatinib) for the therapy of NSCLC in Japan. Osimertinib can be indicated only against T790M+ lung cancer as a second-line therapy. However, whether gefitinib, erlotinib, or afatinib is most appropriate as a first-line therapy is still a controversial issue. The aim of this study was to compare the effectiveness of gefitinib, erlotinib, and afatinib. We retrospectively reviewed… More >

    miR-202 Inhibits Cell Proliferation, Migration, and Invasion by Targeting Epidermal Growth Factor Receptor in Human Bladder Cancer

    Liqing Zhang*, Jianjiang Xu, Gaodi Yang*, Heng Li, Xiuxia Guo§

    Oncology Research, Vol.26, No.6, pp. 949-957, 2018, DOI:doi.org/10.3727/096504018X15149787144385

    Abstract Recent studies have demonstrated that miR-202 is associated with several types of cancer; however, the expression and function of miR-202 have not been investigated in bladder cancer. We analyzed the expression of miR-202 in bladder cancer tissues and adjacent noncancerous tissues. The effect of miR-202 on the proliferation, migration, and invasion was evaluated by in vitro assays. The target gene of miR-202 was assessed by luciferase reporter assay. In this study, miR-202 was found to be significantly downregulated in bladder cancer cell lines and tissues and was highly correlated with the T classification, N classification, More >

    Arya Sobhakumari*1, Kevin P. Orcutt†‡1, Laurie Love-Homan§, Christopher E. Kowalski†‡, Arlene D. Parsons, C. Michael Knudson†‡§¶, Andrean L. Simons*†‡§¶

    Oncology Research, Vol.24, No.1, pp. 55-64, 2016, DOI:10.3727/096504016X14586627440192

    Abstract Poor tumor response to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) is a significant challenge for effective treatment of head and neck squamous cell carcinoma (HNSCC). Therefore, strategies that may increase tumor response to EGFR TKIs are warranted in order to improve HNSCC patient treatment and overall survival. HNSCC tumors are highly glycolytic, and increased EGFR signaling has been found to promote glucose metabolism through various mechanisms. We have previously shown that inhibition of glycolysis with 2-deoxy-d-glucose (2DG) significantly enhanced the antitumor effects of cisplatin and radiation, which are commonly used to treat… More >

    Abstract It has been shown that the high expression of human epididymis protein 4 (HE4) in most lung cancers is related to the poor prognosis of patients, but the mechanism of pathological transformation of HE4 in lung cancer is still unclear. The current study is expected to clarify the function and mechanism of HE4 in the occurrence and metastasis of lung adenocarcinoma (LUAD). Immunoblotting evaluated HE4 expression in lung cancer cell lines and biopsies, and through analysis of The Cancer Genome Atlas (TCGA) dataset. Frequent HE4 overexpression was demonstrated in LUAD, but not in lung squamous… More >

    A New Equalization Method for Lithium-Ion Battery Packs Based on CUK Converter

    Yu Zhang, Sheng Tian*, Yongkang Zhang

    Energy Engineering, Vol.121, No.6, pp. 1459-1472, 2024, DOI:10.32604/ee.2024.047247

    Abstract Aiming at the traditional CUK equalizer can only perform energy equalization between adjacent batteries, if the two single batteries that need to be equalized are far away from each other, there will be the problem of longer energy transmission path and lower equalization efficiency, this paper optimizes the CUK equalizer and optimizes its peripheral selection circuit, which can support the equalization of single batteries at any two positions. The control strategy adopts the open-circuit voltage (OVC) of the battery and the state of charge (SOC) of the battery as the equalization variables, and selects the… More > Graphic Abstract

    Bicuspidization Using the Open-Sleeve Technique for Congenital Aortic Stenosis during Infancy

    Toshi Maeda*, Hiroki Ito, Keiichi Hirose, Kisaburo Sakamoto

    Congenital Heart Disease, Vol.19, No.2, pp. 177-183, 2024, DOI:10.32604/chd.2024.050945

    Abstract Congenital aortic stenosis (cAS) frequently requires intervention during the neonatal or infantile period. However, surgical repair is challenging because of the narrow surgical space. We performed bicuspidization using the open-sleeve technique for cAS with a unicuspid aortic valve in two patients. Postoperatively, the patients were doing well without reintervention for the aortic valve for 8 and 6 years, respectively. Their aortic annular diameter increased along with somatic growth. Bicuspidization for neonates or infancy can be performed safely using the open-sleeve technique as its midterm results have been satisfactory. More > Graphic Abstract
