Inulin, a natural dietary fiber, has various health-promoting bioactivities. However, the impacts of dietary inulin on duck productivity and overall health remain unclear. This study investigated the effects of inulin supplementation on systemic health and its underlying mechanisms by integrating the microbiota and metabolome analyses. One hundred twenty 16-day-old male Cherry Valley ducks with similar initial body weight (BW) were randomly assigned to 20 cages, with two treatments (6 ducks/cage and 10 cages/treatment): a basal diet (CON group) or a basal diet supplemented with 25 g inulin/kg (INU group). The 18-d feeding trials demonstrated that ducks fed the inulin-supplemented diet presented significantly improved growth performance, bone health, and meat quality compared with those in the control group (P < 0.05). Additionally, inulin supplementation reshaped the intestinal microbiota, increasing diversity and the abundance of Alistipes, Ligilactobacillus, and Streptococcus (P < 0.05). Metabolome analysis revealed that inulin feeding significantly modulated 13 metabolites (P < 0.05), which were enriched primarily in health-related metabolic pathways such as taurine and hypotaurine metabolism, steroid hormone biosynthesis, and histidine metabolism. Correlation analysis revealed a positive relationship among the modulated microbes and metabolites and improved healthy parameters. Overall, inulin supplementation improved the bone and muscle health of ducks by specifically modulating key gut microbes, metabolites, and associated metabolic pathways. These findings suggest that inulin supplementation represents a feasible nutritional strategy for improving the meat quality and bone health of intensively raised ducks. © The Author(s) 2025.

Role of NADPH oxidase and its therapeutic intervention in TGF-β-mediated EMT progression: an in vitro analysis on HeLa cervical cancer cells

Epithelial to mesenchymal transition (EMT) is a complex biological event, wherein polarized epithelial cells lose their integrity resulting in a mesenchymal phenotype with enhanced motility, a phenomenon known as metastasis. However, the underlying mechanisms of EMT are still poorly understood in cervical carcinomas. In this study, we investigated the molecular signalling events responsible for the effect of TGF-β, a potent inducer of EMT, on HeLa cervical cancer cells. We observed that TGF-β treatment (5 ng/mL) upregulates the expression of EMT-associated transcription factors such as Snail and Slug and downregulates the expression of epithelial markers such as ZO-1 and E-cadherin. Furthermore, treatment with TGF-β activates both Smad-dependent and Smad-independent signaling pathways, which subsides upon addition of Diphenyleneiodonium (DPI), a potent ROS inhibitor that inhibits NADPH oxidase (NOX). TGF-β treatment enhanced cellular migration and invasion ability was diminished in the presence of ROS inhibitors. In addition, we also observed that ROS-mediated, TGF-β-induced EMT progression was inhibited using therapeutic candidates that target the key signal transduction mediators, including PI3K/AKT, ERK, and P38/MAPK. Accordingly, we demonstrated the involvement of redox biology (NOX2 and NOX4 mediate migration and invasion) in TGF-β-mediated EMT advancement and explored suitable therapeutic interventions.

SU-C-BRB-06: Utilizing 3D Scanner and Printer for Dummy Eye-Shield: Artifact-Free CT Images of Tungsten Eye-Shield for Accurate Dose Calculation

引用

Medical Physics 2015年第6PART2期42卷 3194-3195页

作者： J Park J Lee H Kim I Kim S Ye Program in Biomedical Radiation Sciences Department of Transdisciplinary Studies Graduate School of Convergence Science and Technology Seoul National University Seoul Korea Institute of Radiation Medicine Seoul National University Medical Research Center Seoul Korea Department of Radiation Oncology Seoul National University Hospital Seoul Korea Interdisciplinary Program in Radiation Applied Life Science Seoul National University College of Medicine Seoul Korea Advanced Institutes of Convergence Technology Seoul National University Suwon Korea

Purpose: To evaluate the effect of a tungsten eye-shield on the dose distribution of a patient. Methods: A 3D scanner was used to extract the dimension and shape of a tungsten eye-shield in the STL format. Scanned data was transferred into a 3D printer. A dummy eye shield was then produced using bio-resin (3D systems, VisiJet M3 Proplast). For a patient with mucinous carcinoma, the planning CT was obtained with the dummy eye-shield placed on the patient's right eye. Field shaping of 6 MeV was performed using a patient-specific cerrobend block on the 15 × 15 cm 2 applicator. The gantry angle was 330° to cover the planning target volume near by the lens. EGS4/BEAMnrc was commissioned from our measurement data from a Varian 21EX. For the CT-based dose calculation using EGS4/DOSXYZnrc, the CT images were converted to a phantom file through the ctcreate program. The phantom file had the same resolution as the planning CT images. By assigning the CT numbers of the dummy eye-shield region to 17000, the real dose distributions below the tungsten eye-shield were calculated in EGS4/DOSXYZnrc. In the TPS, the CT number of the dummy eye-shield region was assigned to the maximum allowable CT number (3000). Results: As compared to the maximum dose, the MC dose on the right lens or below the eye shield area was less than 2%, while the corresponding RTP calculated dose was an unrealistic value of approximately 50%. Conclusion: Utilizing a 3D scanner and a 3D printer, a dummy eye-shield for electron treatment can be easily produced. The artifact-free CT images were successfully incorporated into the CT-based Monte Carlo simulations. The developed method was useful in predicting the realistic dose distributions around the lens blocked with the tungsten shield.

Advancing hybrid quantum-classical algorithms via mean operators

Physical Review A 2023年第1期108卷 L010401-L010401页

作者： Donggyu Kim Pureum Noh Hyun-Yong Lee Eun-Gook Moon Department of Physics Korea Advanced Institute of Science and Technology (KAIST) Daejeon 34141 Korea Department of Applied Physics Graduate School Korea University Sejong 30019 Korea Division of Display and Semiconductor Physics Korea University Sejong 30019 Korea Interdisciplinary Program in E·ICT-Culture-Sports Convergence Korea University Sejong 30019 Korea

Hybrid quantum-classical algorithms have been suggested to control the quantum entanglement of many-body systems in noisy intermediate-scale quantum technology, and yet their applicability is limited by the numbers of qubits and quantum operations. Here, we propose a mean-operator theory which overcomes limitations by combining the advantages of hybrid algorithms and standard mean-field theory. We demonstrate that an introduction of a mean operator prepares an entangled target many-body state with a significantly reduced number of quantum operations. We also show that a class of mean operators is expressed as time-evolution operators, which indicates that our theory is directly applicable to quantum simulations with Rydberg atoms and trapped ions.
