    Salman Ahmed1, Fazli Subhan2,3, Mazliham Mohd Su’ud3,*, Muhammad Mansoor Alam3,4, Adil Waheed5

    Computer Systems Science and Engineering, Vol.48, No.6, pp. 1483-1511, 2024, DOI:10.32604/csse.2024.053997 - 22 November 2024

    Abstract In the contemporary era, the death rate is increasing due to lung cancer. However, technology is continuously enhancing the quality of well-being. To improve the survival rate, radiologists rely on Computed Tomography (CT) scans for early detection and diagnosis of lung nodules. This paper presented a detailed, systematic review of several identification and categorization techniques for lung nodules. The analysis of the report explored the challenges, advancements, and future opinions in computer-aided diagnosis CAD systems for detecting and classifying lung nodules employing the deep learning (DL) algorithm. The findings also highlighted the usefulness of DL… More >

    MPPa-PDT induced apoptosis and autophagy through JNK and p38 MAPK signaling pathways in A549 cells

    PINGHUA TU, SHANSHAN WANG, KELAN DENG, XINJUN LI, ZHANLING WU*

    BIOCELL, Vol.48, No.11, pp. 1603-1612, 2024, DOI:10.32604/biocell.2024.054364 - 07 November 2024

    Abstract Objectives: The antitumor effects of pyropheophorbide-α methyl ester-mediated photodynamic therapy (MPPa-PDT) were observed in several cancers. The objective of this investigation was to examine the antineoplastic efficacy of MPPa-PDT acting on lung carcinoma A549 cells and further elaborate mechanisms. Methods: The viability of A549 cells was examined with cell counting kit-8 after MPPa-PDT disposal. Hoechst 33342 staining, monodansylcadaverine (MDC) staining, and transmission electron microscopy were employed to observe apoptotic bodies and autophagic vesicles. Flow cytometry with Annexin V/propidium iodide (PI) labeling objectively assessed cell death. The expression of associated proteins, including Caspase-3, Beclin-1, LC-3II, and More > Graphic Abstract

    BINGJIE LIN1, XIAOBO YING2, CHUANLING ZHANG3,*, GUOJUN ZHANG1,*

    BIOCELL, Vol.48, No.11, pp. 1613-1623, 2024, DOI:10.32604/biocell.2024.053652 - 07 November 2024

    Abstract Objectives: This study explores the protective effects of glycyrrhizic acid (GA) on sepsis-induced cellular damage and inflammation in acute lung injury (ALI), specifically through the modulation of the sirtuin 1 (SIRT1) and high mobility group box 1 (HMGB1) pathway. Methods: The study employed two experimental models: lipopolysaccharide (LPS)-induced BEAS-2B human lung epithelial cells and cecal ligation and puncture (CLP) rats, to simulate sepsis conditions. The cell model involved treatments with LPS, GA, control siRNA (si-NC), and SIRT1-specific siRNA (si-SIRT1). Evaluations included cell viability, apoptosis, and cytokine production. In the rat model, treatments included GA and… More >

    Piperlongumine in combination with EGFR tyrosine kinase inhibitors for the treatment of lung cancer cells

    SHAIL RAKESH MODI, TERRICK ANDEY*

    Oncology Research, Vol.32, No.11, pp. 1709-1721, 2024, DOI:10.32604/or.2024.053972 - 16 October 2024

    Abstract Objectives: EGFR tyrosine kinase inhibitor (EGFR-TKI) therapies such as erlotinib and gefitinib are approved for the treatment of non-small cell lung cancer (NSCLC). However, the high incidence of acquired resistance to these EGFR-TKIs may preclude their effectiveness. Piperlongumine (PPL), an extract from the long pepper fruit (Piper longum), has been shown to possess anticancer properties. The purpose of the study was to investigate piperlongumine as an anticancer agent and to study a combination treatment approach with EGFR-TKIs against lung cancer cells. Methods: Anticancer efficacy of PPL, erlotinib (ERL), gefitinib (GEF), and cisplatin (CIS) were investigated in… More >

    Epidemiological and clinical characteristics of lung cancer in Saudi Arabia: a retrospective study in single oncology center

    YOUSEF KATIB1,*, NASSER MULLA2

    Oncology Research, Vol.32, No.11, pp. 1803-1809, 2024, DOI:10.32604/or.2024.052358 - 16 October 2024

    Abstract Background: Lung cancer (LC) is one of the most common neoplastic diseases and a leading cause of death in Saudi Arabia. Its incidence in Saudi Arabia has increased by more than 3% within two decades. Our study aimed to describe the epidemiological and genetic landscapes of LC in Al-Madinah city in Saudi Arabia.

    Rabia Javed1, Tanzila Saba2, Tahani Jaser Alahmadi3,*, Sarah Al-Otaibi4, Bayan AlGhofaily2, Amjad Rehman2

    CMC-Computers, Materials & Continua, Vol.81, No.1, pp. 809-825, 2024, DOI:10.32604/cmc.2024.052755 - 15 October 2024

    Abstract Cancer poses a significant threat due to its aggressive nature, potential for widespread metastasis, and inherent heterogeneity, which often leads to resistance to chemotherapy. Lung cancer ranks among the most prevalent forms of cancer worldwide, affecting individuals of all genders. Timely and accurate lung cancer detection is critical for improving cancer patients’ treatment outcomes and survival rates. Screening examinations for lung cancer detection, however, frequently fall short of detecting small polyps and cancers. To address these limitations, computer-aided techniques for lung cancer detection prove to be invaluable resources for both healthcare practitioners and patients alike.… More >

    Tanshinone IIA inhibits NLRP3 activation and attenuates alveolar macrophage pyroptosis via the TREM2/β-catenin pathway

    MIN LIU1,*, XIA LI2, JUN LIU1, YU LIU1

    BIOCELL, Vol.48, No.10, pp. 1475-1487, 2024, DOI:10.32604/biocell.2024.053227 - 02 October 2024

    Abstract Background: Alveolar macrophage pyroptosis exacerbates inflammatory lung diseases, and tanshinone IIA is known for its anti-inflammatory properties. Thus, understanding how tanshinone IIA affects alveolar macrophage pyroptosis is essential. Methods: NR8383 cells were exposed to lipopolysaccharide (LPS) and adenosine triphosphate (ATP). We assessed cell viability, pyroptosis, and the expression of triggering receptors expressed on myeloid cells 2 (TREM2), p-β-catenin, β-catenin, and pyroptosis-related factors. We also examined the interaction between tanshinone IIA and TREM2. Results: Co-stimulation with LPS and ATP significantly reduced NR8383 cell viability, increased pyroptosis, and upregulated pyroptosis-associated factors. Treatment with tanshinone IIA mitigated these effects.… More >
