    NATURAL CONVECTIVE HEAT TRANSFER FROM A NARROW VERTICAL FLAT PLATE WITH A UNIFORM SURFACE HEAT FLUX AND WITH DIFFERENT PLATE EDGE CONDITIONS

    Patrick H. Oosthuizen*, Jane T. Paul

    Frontiers in Heat and Mass Transfer, Vol.1, No.1, pp. 1-8, 2010, DOI:10.5098/hmt.v1.1.3006

    Abstract Natural convective heat transfer from narrow vertical plates which have a uniform surface heat flux has studied. With a narrow plate the heat transfer rate is dependent on the flow near the vertical edges of the plate. The magnitude of the edge effects will depend on the conditions existing near the edges of the plate. Three situations have here been considered these being a heated plate imbedded in a large plane adiabatic surface, the surfaces of the heated plane and the adiabatic surface being in the same plane, a heated plate with plane adiabatic surfaces above and below the heated… More >

    Oncology Research, Vol.32, No.4, pp. 615-624, 2024, DOI:10.32604/or.2024.044029

    Abstract Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive solid malignancies. A specific mechanism of its metastasis has not been established. In this study, we investigated whether Neural Wiskott-Aldrich syndrome protein (N-WASP) plays a role in distant metastasis of PDAC. We found that N-WASP is markedly expressed in clinical patients with PDAC. Clinical analysis showed a notably more distant metastatic pattern in the N-WASP-high group compared to the N-WASP-low group. N-WASP was noted to be a novel mediator of epithelial-mesenchymal transition (EMT) via gene expression profile studies. Knockdown of N-WASP in pancreatic cancer cells significantly inhibited cell invasion, migration,… More > Graphic Abstract

    GRIK1 promotes glioblastoma malignancy and is a novel prognostic factor of poor prognosis

    GUOQIANG HOU1,2,#, XINHANG XU2,#, WEIXING HU1,*

    Oncology Research, Vol.32, No.4, pp. 727-736, 2024, DOI:10.32604/or.2023.043391

    Abstract Primary tumors of the central nervous system (CNS) are classified into over 100 different histological types. The most common type of glioma is derived from astrocytes, and the most invasive glioblastoma (WHO IV) accounts for over 57% of these tumors. Glioblastoma (GBM) is the most common and fatal tumor of the CNS, with strong growth and invasion capabilities, which makes complete surgical resection almost impossible. Despite various treatment methods such as surgery, radiotherapy, and chemotherapy, glioma is still an incurable disease, and the median survival time of patients with GBM is shorter than 15 months. Thus, molecular mechanisms of GBM… More >

    Abstract Increasing life expectancy and an aging population lead to age-related bone diseases like osteoporosis and low bone mass more prevalent. These conditions represent a common, costly and chronic burden, not only for elderly but also to society at large. Consequently, elucidating the pathophysiology and developing effective therapies for these diseases is of paramount importance. Recent advances in research have identified the gut as a novel and promising target for addressing bone disorders, giving rise to the concept of the “gut-bone axis”. An in-depth review of the latest insights into the effects of age-related physiological changes in the gastrointestinal tract on… More >

    BIOCELL, Vol.48, No.3, pp. 431-441, 2024, DOI:10.32604/biocell.2023.046484

    Abstract Background: Sepsis, a type of systemic disease, can impact nearly all organs, tissues and cells. Among them, endothelial cells are amongst the first to be affected and respond to the insult. In this study, we investigated the protective effects of microRNA-30a-5p (miR-30a-5p) on human pulmonary microvascular endothelial cells (HPMECs) treated with lipolysaccharide (LPS). Methods: An in vitro model of sepsis was established in HPMECs with the use of LPS. Transfecting with different tools (mimetic and inhibitor) to modify miR-30a-5p expression. Cell viability, proliferation and apoptosis were detected by the CCK-8 assay, the EdU kit and fluorescence staining, respectively. The autophagy-related… More >
