Objective
This study aims to explore the possible mechanism of miR-29a inhibiting papillary thyroid carcinoma (PTC) through the downregulation of TAGLN2. The paper expects to find novel targets for PTC treatment and prognosis improvement, and is also of great significance in enhancing the overall therapeutic level of PTC and improving life quality of patients.
Methods
Changes in PTC cell growth, migration, and invasive ability were respectively detected using MTS assays, wound healing experiments, and Matrigel matrix invasion assays. Expressions of E-cadherin, N-cadherin, vimentin, and MMP2 were determined by Western blotting. Differences in protein expressions between groups were compared. Overexpression and knockdown of TAGLN2 were performed in K1 cells, and the expression levels of PI3K/AKT pathway protein in K1 cells were detected by Western blotting.
Result
miR-29a significantly inhibited the proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of K1 cells. Overexpression of miR-29a played an important role in improving the malignant phenotype of PTC by regulating the expression of actin-binding protein TAGLN2. Overexpression of TAGLN2 can counteract the inhibitory effect of miR-29a on K1 cells. TAGLN2 can activate the PI3K/AKT signaling pathway, indicating that it may promote the progress of EMT by activating PI3K/AKT.
Conclusion
The miR-29a/TAGLN2 axis may affect the malignant phenotype of K1 cells by regulating downstream PI3K/AKT signaling pathways, thus providing a new target for the treatment of PTC.

This research focuses on a manner in which bitumen-WO₃ (petroleum-derived bitumen mixed with tungsten trioxide nanoparticles) materials can be a good shielding candidate against gamma radiation. The objective we set in mixing WO₃ nanoparticles with bitumen was to take advantage of both the bitumen's natural qualities and the WO₃'s excellent shielding capabilities. The prepared composites were tested against various gamma-ray energies emitted from multiple gamma-ray sources to examine their shielding capabilities. The X-ray diffraction (XRD) analysis of the composites' structural properties verified the effective integration of the WO₃ with the bitumen structure. Scanning electron microscopy (SEM) showed that microstructural changes, such as an increase in material density and an improvement in particle dispersion, are caused by a rise in WO3 concentration, which is an essential step toward efficient shielding. Then, the Mean Free Path (MFP), Half-value Layer (HVL), and Linear Attenuation Coefficients (μl) were computed, showing that the composite's capacity to reduce gamma radiation is much enhanced by raising the WO₃ content, especially at lower gamma-ray energies. For instance, at 20 keV, the LAC of 50 wt% WO₃-bitumen composite increased to 9.18 cm⁻1 compared to pure bitumen's 0.40 cm⁻1, while the HVL decreased from 1.73 cm to 0.08 cm, and the MFP dropped from 2.3 cm to 0.1 cm” The results demonstrate the potential of bitumen-WO₃ composites as a sustainable and efficient material for radiation shielding, particularly highlighting their applicability in various sectors, including the development of building wall paints against gamma radiation.

CT radiography is a non-invasive imaging diagnostic technique, which has the potential to evaluate the condition of patients with bronchial asthma, predict the curative effect and guide the treatment. The purpose of this study was to investigate the effects of targeted nursing based on CT radiographic examination on the rehabilitation and psychological intervention of patients with bronchial asthma. In the experimental group, CT radiographic examination was performed. The test is a non-invasive diagnostic imaging technique that uses a radioactive tracer, which is injected into the patient. The patient's chest is then scanned using a CT scanning device to obtain detailed still and moving images. During the scan, the patient needs to maintain the proper position and breathing pattern to ensure a clear image, which can be analyzed and interpreted. Based on the results of CT radiographic images, the treatment plan is developed and adjusted according to the individual patient's situation and needs. By tailoring treatment to the patient's specific circumstances, targeted care is able to better respond to the patient's symptoms and disease progression. The control group received conventional treatment. By collecting clinical data, CT image results and evaluation indexes of rehabilitation effect, the two groups of patients were compared and analyzed. Patients in the experimental group showed better remission and improved respiratory function during recovery, with significant differences compared to the control group. Patients in the experimental group also showed significant improvements in their mental state and quality of life.

The purpose of this study was to investigate the application value of radiography in the treatment of allergic rhinitis asthma syndrome (ARAS) with traditional Chinese medicine, and objectively evaluate the effect of traditional Chinese medicine on ARAS by comparing the imaging changes before and after treatment. The treatment group received comprehensive treatment with traditional Chinese medicine. All patients underwent radiographic X-ray examination before and after treatment to evaluate the imaging changes of nasal cavity and lung, and at the same time, symptom scores and pulmonary function indexes were recorded. The imaging data were evaluated by two independent radiologists and the treatment effect was analyzed statistically. In the treatment group, the inflammation of nasal cavity and lung was significantly reduced by X-ray images after TCM treatment, and the proportion of patients with normal structure was significantly higher than that in the control group (P < 0.05). Although the control group also showed some improvement in imaging and clinical indicators, the effect was not as significant as that of the treatment group. The results show that traditional Chinese medicine has a significant effect on the treatment of ARAS, and the imaging changes before and after treatment can be visually observed through X-ray image examination, so as to provide scientific basis for clinical treatment.
本研究旨在探讨放射影像学在中药治疗过敏性鼻炎哮喘综合征（ARAS）中的应用价值，并通过比较治疗前后的影像学变化，客观评价中药对过敏性鼻炎哮喘综合征的疗效。治疗组接受中药综合治疗。所有患者在治疗前后均接受 X 光检查，评估鼻腔和肺部的影像学变化，同时记录症状评分和肺功能指标。由两名独立的放射科医生对影像学数据进行评估，并对治疗效果进行统计学分析。经中医治疗后，治疗组患者的鼻腔和肺部炎症明显减轻，结构正常的比例明显高于对照组（P < 0.05）。对照组虽然在影像学和临床指标上也有一定改善，但效果不如治疗组明显。结果表明，中药治疗ARAS效果显著，通过X线影像学检查可直观观察治疗前后的影像学变化，为临床治疗提供科学依据。

Thrombolism refers to the pathological state that the body is prone to thrombosis, which seriously affects the quality of life and life safety of patients. It is necessary to screen and prevent the etiology of thrombolism as early as possible to reduce its incidence and related complications. The purpose of this study was to explore the application effect of radiation-based CT imaging in the etiology screening and disease prevention of thrombolism, in order to provide a reliable diagnosis and prevention means for clinical practice. The study included a large number of 200 patients with suspected thromboembolism who received treatment. All patients underwent radiative CT imaging to evaluate vascular structure and hemodynamic changes. By analyzing the characteristics of blood vessel structure and thrombus morphology, the potential causes of thrombus formation can be screened out. Hemodynamic parameters such as the degree of vascular obstruction and blood flow velocity were evaluated to predict the risk of thrombosis. Combined with the detection of blood clot markers in laboratory, the screening effect on the causes of thrombolysis was analyzed. It has been found that radiative CT imaging can accurately identify the risk factors of thrombolysis such as vascular stenosis, vascular wall abnormality and blood flow obstruction. Compared with traditional detection methods, radiative CT has higher sensitivity and specificity in early diagnosis of thrombolism. The individualized prevention program combined with the imaging results significantly reduced the incidence of thrombus.

Early diagnosis of pediatric tic disorders (TD) is crucial for effective therapeutic intervention and management, which can significantly improve neurological development and psychological well-being from childhood through adulthood. However, current pediatric TD diagnostic methodologies suffer from low specificity and sensitivity, as they rely primarily on the subjective expertise of clinicians. Herein, we demonstrated a non-invasive approach for deep learning-assisted diagnosis of pediatric TD. A residual neural network model was developed to predict TD using electroencephalogram (EEG) signals. The optimized model analyzed preprocessed EEG data to generate diagnostic reports indicating the probability of TD occurrence, thus providing deep learning-assisted support for clinical decisions. The clinical features of EEG signals in pediatric TD are elucidated through extensive analysis. Predictive accuracy of EEG decreases over time, with short-term EEG indicating that right hemisphere EEG activity is a predominant clinical feature of TD. A computer-based application was developed and implemented to calculate the probability of TD based on individual EEG patterns, thereby assisting clinicians with diagnostic decision-making in real-world scenarios. This work not only proposes a non-invasive and accurate approach for TD diagnosis but also contributes to the early intervention and long-term management of neurological and psychological health in affected individuals.

Image generation techniques have made remarkable progress in the digital image processing and computer vision. However, traditional generation models cannot meet the complexity and diversity requirements of patterned images. In view of this, the study aims to enhance the quality of generated pattern images, which uses improved residual block, and introduces a self-attention mechanism to compute the weight parameters of the input features to enhance the accuracy. Comparing with three image generation models, the research model shows lower Frechette initial distance, which is better than the other three methods, and the average Frechette initial distance values in the four scenes are 175.23, 176.41, 174.41, and 165.23. Generated mouths and eyes: the average values of Frechette initial distances reach 98.23 and 97.24, respectively. For emotion classification, the Frechette initial distance averages for sad, excited, and calm emotions were 82.34, 75.63, and 70.21, respectively. The model was trained up to 2500 iterations, and the loss value was reduced to 0.54, with an accuracy of 98.23%, confirming its effectiveness and high performance. The self attention residual network enhances the model's ability to capture image details, effectively improving the quality and accuracy of image generation, and providing a new technological path for radiation imaging data processing and analysis in radiation science.

Comparing with three image generation models, the research model shows lower Frechette initial distance, which is better than the other three methods, and the average Frechette initial distance values in the four scenes are 175.23, 176.41, 174.41, and 165.23. Generated mouths and eyes: the average values of Frechette initial distances reach 98.23 and 97.24, respectively. For emotion classification, the Frechette initial distance averages for sad, excited, and calm emotions were 82.34, 75.63, and 70.21, respectively. The model was trained up to 2500 iterations, and the loss value was reduced to 0.54, with an accuracy of 98.23%, confirming its effectiveness and high performance. The self attention residual network enhances the model's ability to capture image details, effectively improving the quality and accuracy of image generation, and providing a new technological path for radiation imaging data processing and analysis in radiation science.</div></div>","PeriodicalId":16920,"journal":{"name":"Journal of Radiation Research and Applied Sciences","volume":"17 4","pages":"Article 101157"},"PeriodicalIF":1.7,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142539783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This current attempt develops a more efficient predictive model that can accurately simulate the behavior of Carreau trihybrid nanofluids in non-trivial configurations. This study interprets thermal behavior of Carreau trihybrid nanofluid model with streamline analysis considering the two geometries wedge and cone. Three nanoparticles are involved in base fluid (water) with physical effects of non-uniform heat sink source and nonlinear thermal radiation are assumed for heat transport and Lorentz forces are considered for velocity inspection. Furthermore, this study employs intelligent neural networks to interpret data for streamline and thermal transport analysis, focusing on the specific cases of wedge and cone geometries. Initial data fetched through bvp4c and further, obtained data trained through supervised neural scheme, Levenberg marquardt neural network (LM-NN) is applied and required predictions are made. Higher “Gc” indicates stronger solutal buoyancy forces, which promote upward fluid movement, thereby increasing the velocity gradient. With increasing (M), the velocity profile decreases. Fluid exhibits enhancing the velocity gradient with higher (n). Higher particle concentration enhances the fluid's viscosity and resistance.

In this research article, the bioconvection of oxytactic microorganisms with magneto-hydrodynamic (MHD) 3D steady flow of Sisko nanomaterial over a stretching sheet through convective conditions is deliberated and analyzed. Possessions of thermophoresis, Brownian motion as well as mixed convection in the Sisko fluid are also deliberated. Sisko fluid is supposed to be electrically conducted over and done with a constant pragmatic magnetic field. The flow problem is communicated using governing relations and problem is transmuted into dimensionless form among non-similar procedure. To obtain convergent solutions we must solve nonlinear differential systems. The consequences of several physical parameters have been deliberate and discussed. Our results displayed that the higher microorganism difference parameter condensed the microorganism profile, while an opposite influence is established for magnetic parameter. Concentration proises of the Sisko fluid flow are improved by growing Biot number whereas contracted beside the Lewis number. In recent years, the scientists have shown great attention in the field of bioconvection owing to its countless applications such as amassing the cells, bioreactors, gas-bearing sedimentary, modeling oil, exclusion of living, and nonliving cells, and lots of additional.
