    Survey of Indoor Localization Based on Deep Learning

    Khaldon Azzam Kordi1, Mardeni Roslee1,*, Mohamad Yusoff Alias1, Abdulraqeb Alhammadi2, Athar Waseem3, Anwar Faizd Osman4

    CMC-Computers, Materials & Continua, Vol., , DOI:10.32604/cmc.2024.044890

    Abstract This study comprehensively examines the current state of deep learning (DL) usage in indoor positioning. It emphasizes the significance and efficiency of convolutional neural networks (CNNs) and recurrent neural networks (RNNs). Unlike prior studies focused on single sensor modalities like Wi-Fi or Bluetooth, this research explores the integration of multiple sensor modalities (e.g., Wi-Fi, Bluetooth, Ultra-Wideband, ZigBee) to expand indoor localization methods, particularly in obstructed environments. It addresses the challenge of precise object localization, introducing a novel hybrid DL approach using received signal information (RSI), Received Signal Strength (RSS), and Channel State Information (CSI) data to enhance accuracy and stability.… More >

    miR-557 suppresses hepatocellular carcinoma cell proliferation and migration via downregulating CBX4

    XULONG SUN1,#, WENTAO DING2,#, CHAO JIANG3, ZHIAN FANG4,*

    BIOCELL, Vol., , DOI:10.32604/biocell.2024.050519

    Abstract Introduction: Hepatocellular carcinoma (HCC), a prevalent malignancy, poses significant challenges with high tumor heterogeneity and poor prognosis. MicroRNAs (miRNAs) play a pivotal role in hepatocarcinogenesis. Although abnormalities in microRNA-557 (miR-557) expression have been implicated in various cancer types, its role in HCC remains unclear. Therefore, there is a need to explore the function of microRNA-557 in HCC. Methods: Candidate miRNAs were identified through screening in GSE108724 and GSE20077. Real-time PCR was employed to analyze the expression level of miR-557 in hepatoma cell lines and tissues. Cell viability and migration assays were applied to assess the impact of miR-557 on HCC… More > Graphic Abstract

    Impact of Varying Blower Opening Degrees on Indoor Environment and Thermal Comfort

    Shengqiang Shi1,2,*, Abdelatif Merabtine3, Rachid Bennacer4, Julien Kauffmann2

    FDMP-Fluid Dynamics & Materials Processing, Vol., , DOI:10.32604/fdmp.2024.050547

    Abstract At present, air handling units are usually used indoors to improve the indoor environment quality. However, while introducing fresh air to improve air quality, air velocity has a certain impact on the occupants’ thermal comfort. Therefore, it is necessary to explore the optimization of air-fluid-body interaction dynamics. In this study, the indoor air flow was changed by changing the opening and closing degree of the blower, and the thermal manikin is introduced to objectively evaluate the human thermal comfort under different air velocities. The main experimental results show that the air change rate increases with the increase of the opening… More >

    Abstract This review aimed to describe the inculpation of microRNAs (miRNAs) in thyroid cancer (TC) and its subtypes, mainly medullary thyroid carcinoma (MTC), and to outline web-based tools and databases for bioinformatics analysis of miRNAs in TC. Additionally, the capacity of miRNAs to serve as therapeutic targets and biomarkers in TC management will be discussed. This review is based on a literature search of relevant articles on the role of miRNAs in TC and its subtypes, mainly MTC. Additionally, web-based tools and databases for bioinformatics analysis of miRNAs in TC were identified and described. MiRNAs can perform as oncomiRs or antioncoges,… More > Graphic Abstract

    Reversal of tamoxifen resistance by artemisinin in ER+ breast cancer: bioinformatics analysis and experimental validation

    ZHILI ZHUO#, DONGNI ZHANG#, WENPING LU*, XIAOQING WU, YONGJIA CUI, WEIXUAN ZHANG, MENGFAN ZHANG

    Oncology Research, Vol., , DOI:10.32604/or.2024.047257

    Abstract Breast cancer is the leading cause of cancer-related deaths in women worldwide, with Hormone Receptor (HR)+ being the predominant subtype. Tamoxifen (TAM) serves as the primary treatment for HR+ breast cancer. However, drug resistance often leads to recurrence, underscoring the need to develop new therapies to enhance patient quality of life and reduce recurrence rates. Artemisinin (ART) has demonstrated efficacy in inhibiting the growth of drug-resistant cells, positioning art as a viable option for counteracting endocrine resistance. This study explored the interaction between artemisinin and tamoxifen through a combined approach of bioinformatics analysis and experimental validation. Five characterized genes (ar,… More > Graphic Abstract

    Bendamustine and rituximab as frontline therapy in extranodal marginal zone lymphoma: a single-institution experience

    CONSTANTINE N. LOGOTHETIS1, NATHAN P. HORVAT2, TONY KURIAN3, CELESTE BELLO3, JULIO CHAVEZ3, LEIDY ISENALUMHE3, BIJAL SHAH3, LUBOMIR SOKOL3, HAYDER SAEED3, JAVIER PINILLA3, SAMEH GABALLA3,*

    Oncology Research, Vol., , DOI:10.32604/or.2024.046885

    Abstract Extranodal marginal zone lymphoma (EMZL) encompasses 70% of cases of marginal zone lymphoma. Frontline bendamustine and rituximab (BR) were derived from trials involving other indolent non-Hodgkin’s lymphomas. Only one trial has evaluated frontline BR prospectively in EMZL. This retrospective study reports outcomes among EMZL patients receiving frontline BR. Twenty-five patients were included with a median age of 69 years (40–81). Five (20.0%) patients had stage I/II disease, and 20 (80.0%) had stage III/IV disease. The median number of cycles was 6.0 (3.0–6.0). Maintenance rituximab was administered to 10 (41.7%) individuals. Overall response rate (ORR) was 100.0% (60.0% complete response, 40.0%… More >

    Tmem39b promotes tumor progression and sorafenib resistance by inhibiting ferroptosis in hepatocellular carcinoma

    MING ZHUANG, XUE ZHANG, LU LI, LIMING WEN, JIAMIN QIN*

    Oncology Research, Vol., , DOI:10.32604/or.2024.046170

    Abstract Hepatocellular carcinoma (HCC) poses a significant threat to human health. Resistance to sorafenib in the chemotherapy of HCC is a common and significant issue that profoundly impacts clinical treatment. While several members of the transmembrane (TMEM) protein family have been implicated in the occurrence and progression of HCC, the association between TMEM39b and HCC remains unexplored. This study revealed a significant overexpression of TMEM39b in HCC, which correlated with a poor prognosis. Subsequent investigation revealed that RAS-selective lethal 3 (RSL3) induced pronounced ferroptosis in HCC, and knocking down the expression of TMEM39b significantly decreased its severity. Similarly, following the induction… More >

    WEI JIANG1, MEI ZHOU2,*

    Oncology Research, Vol., , DOI:10.32604/or.2024.043423

    Abstract Multiple myeloma (MM) is a plasma cell malignancy and remains incurable as it lacks effective curative approaches; thus, novel therapeutic strategies are desperately needed. The study aimed to explore the therapeutic role of dihydromyricetin (DHM) in MM and explore its mechanisms. Human MM and normal plasma samples, human MM cell lines, and normal plasma cells were used for in vitro experiments. Cell counting kit-8 (CCK-8), flow cytometry, and trans-well assays were performed for the assessment of cell viability, apoptosis, migration, and invasion, respectively. Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to assess the mRNA expression of signal transducer and… More > Graphic Abstract
