    Monitoring Vegetation Cover Changes in a Rapidly Urbanizing Region: A Case Study in Da Nang City, Vietnam

    Vu Thi Phuong1, Bui Bao Thien2,*

    Revue Internationale de Géomatique, Vol.34, pp. 151-168, 2025, DOI:10.32604/rig.2025.062829 - 21 March 2025

    Abstract Vegetation is crucial to ecosystems, thus, detecting and assessing changes in vegetation cover are receiving increasing attention. In this study, we combine remote sensing data and geographic information systems to assess vegetation cover changes in Da Nang city, Vietnam, between 1988 and 2022. Remote sensing images for the years 1988, 2000, and 2010 were obtained from Landsat 5-TM satellite data, and imagery for 2022 was obtained from Landsat 9-OLI/TIRS satellite data. In each satellite scene, we used supervised classification and spectral indices (NDWI—Normalized Difference Water Index, NDVI—Normalized Difference Vegetation Index, and SAVI—Soil Adjusted Vegetation Index) More >

    Assessing the impact of CD73 inhibition on overcoming anti-EGFR resistance in glioma cells

    LUIZ FERNANDO LOPES SILVA1,#, JULIETE NATHALI SCHOLL1,#, AUGUSTO FERREIRA WEBER1, CAMILA KEHL DIAS1, PAULINE RAFAELA PIZZATO2, VINíCIUS PIERDONá LIMA1, JEAN SÉVIGNY3,4, ANA MARIA OLIVEIRA BATTASTINI1, FABRÍCIO FIGUEIRÓ1,2,*

    Oncology Research, Vol.33, No.4, pp. 951-964, 2025, DOI:10.32604/or.2024.055508 - 19 March 2025

    Abstract Objectives: Glioblastoma (GB) is a grade IV glial tumor characterized by high malignancy and dismal prognosis, primarily due to high recurrence rates and therapeutic resistance. The epidermal growth factor receptor (EGFR), a receptor tyrosine kinase (RTK), regulates signaling pathways, including cell growth, proliferation, survival, migration, and cell death. Many cancers utilize immune checkpoints (ICs) to attenuate immune responses. CD73 is an enzyme that functions as an IC by hydrolyzing AMP to adenosine, suppressing immune cells in the tumor microenvironment. However, the role of CD73 in resistance to EGFR inhibitors is poorly understood. This study aims… More >

    Abstract Background: Non-small cell lung cancer (NSCLC) is often accompanied by brain metastasis (BM), and the prognosis of patients with BM is poor. This study assesses the prognostic impact of BM in NSCLC patients with epidermal growth factor receptor (EGFR) mutations. Methods: We retrospectively evaluated 692 advanced NSCLC patients with EGFR mutations treated with tyrosine kinase inhibitors (TKIs) at West China Hospital from 2015 to 2019. The overall survival rate (OS), progression-free survival rate (PFS), objective response rate (ORR), disease control rate (DCR), and clinical parameters of the BM and non-BM groups were compared. Univariable and multivariable… More >

    Exploring the mechanistic role of epidermal growth factor receptor activation in non-cancer kidney disease

    JU-YEON LEE1, DAEUN MOON2, JINU KIM2,3,*

    BIOCELL, Vol.49, No.1, pp. 79-92, 2025, DOI:10.32604/biocell.2024.058340 - 24 January 2025

    Abstract The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein that plays a crucial role in signal transduction and cellular responses. This review explores the function of EGFR in kidney physiology and its implications for various kidney diseases. EGFR signaling is essential for kidney function and repair mechanisms, and its dysregulation significantly impacts both acute and chronic kidney conditions. The review discusses the normal distribution of EGFR in kidney tubular segments, the mechanism of its activation and inhibition, and the therapeutic potential of EGFR-targeting antagonists and ligands. Additionally, it explores the pathophysiological characteristics observed More >

    Robust Backstepping Control of a Quadrotor Unmanned Aerial Vehicle under Colored Noises

    Mehmet Karahan*

    CMC-Computers, Materials & Continua, Vol.82, No.1, pp. 777-798, 2025, DOI:10.32604/cmc.2024.059123 - 03 January 2025

    Abstract Advances in software and hardware technologies have facilitated the production of quadrotor unmanned aerial vehicles (UAVs). Nowadays, people actively use quadrotor UAVs in essential missions such as search and rescue, counter-terrorism, firefighting, surveillance, and cargo transportation. While performing these tasks, quadrotors must operate in noisy environments. Therefore, a robust controller design that can control the altitude and attitude of the quadrotor in noisy environments is of great importance. Many researchers have focused only on white Gaussian noise in their studies, whereas researchers need to consider the effects of all colored noises during the operation of… More >

    Rapid onset severe hyperkalemia during robotic radical cystectomy: a case report

    Matthew Buell, Brian Hu

    Canadian Journal of Urology, Vol.31, No.5, pp. 12026-12029, 2024

    Abstract Radical cystectomy is a preferred treatment for muscle invasive bladder cancer. Despite known complications, rapid onset, severe hyperkalemia necessitating abortion of surgery has not been reported. In this case report, a patient with end stage renal disease (ESRD) undergoing attempted cystectomy developed severe intraoperative hyperkalemia and acidosis that led to abortion of surgery and transfer to the medical intensive care unit for emergent hemodialysis. The multifactorial etiology was related to respiratory acidosis, ESRD, patient positioning, clipping of ureters, and body habitus, as well as an idiopathic element. Knowledge of hyperkalemia etiologies can assist in diagnosis More >

    A Surrogate Model for Rapid Solution of Acoustic Wave Equation Based on the Boundary Element Method and Fourier Neural Operators

    Ruoyan Li1,2, Wenjing Ye1,*, Yijun Liu2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.32, No.1, pp. 1-1, 2024, DOI:10.32604/icces.2024.012150

    Abstract A modern approach to control sound is through the development of sound-control materials/structures, which enable a wide range of applications such as noise reduction and non-contact particle manipulation. Designing these sound-controlling metamaterials requires accurate and efficient simulation methods for solving the unbounded acoustic wave equation with changing domain and frequencies. To facilitate the design optimization, surrogate models that are significantly more efficient than full-scale simulations are highly desirable. In this work, we present our recent work on the development of such surrogate models based on the concept of Fourier neural operators (FNO). FNO was originally… More >

    Unique Mechanism in Strength and Deformation of Natural Nano-Sized Fibers: Molecular Dynamics Study on Nanofibrils of Cellulose and Spider Silk

    Ken-ichi Saitoh1,*, Makoto Watanabe2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.31, No.3, pp. 1-1, 2024, DOI:10.32604/icces.2024.012624

    Abstract Natural nanofibers, e.g., cellulose nanofiber (CNF) of plant, collagen fibril in human body and fibroin fiber in spider silk, show interesting and distinctive atomistic mechanisms in deformation under mechanical loading as well as exhibition of extraordinary strength. These fibers are comprising more larger bulk and wire materials by constructing structural hierarchy. However, the initiation of unique behavior of these materials largely originates from atomic-scale and chemical energetics in loading. Besides, the experimental approach is often difficult and is too limited to reveal the basic mechanism. Therefore, it is crucial to clarify atomic behavior of these… More >

    Environmental Influences on Biological Membranes

    Choon-Peng Chng1, Changjin Huang1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.31, No.2, pp. 1-1, 2024, DOI:10.32604/icces.2024.011464

    Abstract Biological membranes play crucial roles in cellular functions, serving as dynamic interfaces that regulate the passage of molecules and signals between the cell and its environment. Understanding how these membranes respond to environmental stimuli is paramount in elucidating cellular adaptation and survival mechanisms. In this talk, we will present our recent studies on the structural and mechanical changes of biological membranes in response to two different environmental factors, including the presence of reactive oxygen species (ROS) and dehydration. Through systematic molecular dynamics simulations, we have revealed a dynamic interplay between membrane components, membrane mechanics and… More >
