Abstract (sommario):

In cancer cells, telomeres are constantly repaired by telomerase allowing them to avoid reaching a critical length where the cell becomes senescent. Overtime, aerobic respiration in the mitochondria can create an increase in intracellular reactive oxygen species (ROS) that causes telomerase reverse transcriptase (hTERT), the catabolic subunit of telomerase, to exit the nucleus. Without hTERT in the nucleus, telomerase cannot function to repair telomere ends, inducing senescence. One effect of increased ROS production is the activation of calcium channels leading to an increase in intracellular calcium. We attempted to mimic this ROS induced increase in intracellular calcium levels by administering 0.5uM of Thapsigargin to HeLa cells in order to determine if an increase in calcium levels alone would be sufficient to cause hTERT to exit the nucleus. Immunofluorescene was used to visualize fluorescent intensities of hTERT in the nucleus after administration of the drug in conjunction with visualization of Ran as an indicator of functional nuclear transport. We predicted thapsigargin would disrupt nuclear transport and cause hTERT to exit the nucleus. Image J software was used to compare nuclear fluorescence intensities between treated and control cells. Our results indicated that administration of thapsigargin caused a significant decrease in nuclear levels of hTERT in conjunction with decreased nuclear levels of Ran. Our findings could provide a potential method to induce cellular senescence in cancer cells by inducing mislocalization of hTERT and Ran.

Abstract (sommario):

To investigate useful cytological features for differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), this study cytologically compared HCC to ICC using image analysis software. Touch smear specimens of surgically resected specimens were obtained from a total of 61 nodules of HCC and 16 of ICC. The results indicated that the major/minor axis ratio of ICC is significantly larger than that of HCC (1.67 ± 0.27 vs. 1.32 ± 0.11, p < 0.0001) in Papanicolaou staining. This result means that the nucleus of HCC is close to round and the nucleus of ICC is close to an oval. This significant difference in the major/minor axis ratio between ICC and HCC was consistently observed by the same analyses using clinical samples of cytology (4 cases of HCC and 13 cases of ICC) such a fine-needle aspiration, brushing and ascites (ICC: 1.45 ± 0.13 vs. HCC: 1.18 ± 0.056, p = 0.004). We also confirmed that nuclear position center-positioned nucleus (p < 0.0001) and granular cytoplasm (p < 0.0001) are typical features of HCC tumor cells compared to ICC tumor cells. The research study found a significant difference in the nuclear morphology of HCC (round shape) and ICC (oval shape) in Papanicolaou-stained cytology specimens. This simple and objective finding will be very useful for the differential cytodiagnosis of HCC and ICC.

Abstract (sommario):

To solve the problems of rough edge and poor segmentation accuracy of traditional neural networks in small nucleus image segmentation, a nucleus image segmentation technology based on U-Net network is proposed. First, the U-Net network is used to segment the nucleus image, which stitches the feature images in the channel dimension to achieve feature fusion, and the skip structure is used to combine the low- and high-level features. Then, the subregional average pooling is proposed to improve the global average pooling in the attention module, and an attention channel expansion module is designed to improve the accuracy of image segmentation. Finally, the improved attention module is integrated into the U-Net network to achieve accurate segmentation of the nuclear image. Based on the Python platform, the experimental results show that the proposed segmentation technology can achieve fast convergence, and the mean intersection over union (MIoU) is 85.02%, which is better than other comparison technologies and has a good application prospect.

Abstract (sommario):

253 Background: CTC enumeration but not CTC morphology has been reported to predict outcomes to treatment in men with mCRPC. Recently Chen JF et. al (Cancer, 2015) showed an association with nuclear size and incidence of visceral disease in metastatic prostate cancer. In this study, we investigate the impact of CTC nucleus size on outcomes in men treated with AA for mCRPC. Methods: In a cohort of men with mCRPC treated with first-line AA, who had CTCs identified by CellSearch (CS) analysis prior to initiating treatment, we retrospectively quantified the nuclear size of CTCs by ImageJ/Fiji 1.46 software and correlated with progression free survival (PFS) on AA. We analyzed with univariate in addition to pre-specified multivariable analysis adjusted for Gleason score and baseline log PSA to assess independent predictive value of CTC nuclear size on PFS. Median PFS was calculated by Kaplan-Meier analysis and p-values were determined from Cox proportional hazards model. Results: 22 men treated with AA for mCRPC were included. Median nucleus size was 23.8 µm. Patients were divided in to 2 cohorts: small nuclear cohort (CTC nucleus size < 23.8 µm) vs large nuclear cohort (CTC nucleus size ≥23.8 µm). There was a non-significant trend towards worsened PFS (5.8 versus 6.8 months) in the larger nuclear size arm (Table). Conclusions: In this cohort of men with CRPC treated with AA, there is a non-significant trend towards decreased PFS associated with larger CTC nucleus size. Data are hypothesis generating and require further interrogation in a larger cohort. [Table: see text]

Abstract (sommario):

Introduction. Nuclei of oculogyric nerves (principal oculomotor nucleus, trochlear nucleus and abducens nucleus) are densely vascularized brain?stem structures. The aim of this study was to determine quantitative characteristics of the vascular network of these nuclei. Material and methods. The study was done on 30 adult brainstems, both male and female, without diagnosed neurological disturbances. Three-millimetrethick stratums were taken in transversal plane and cut in 0.3 micrometer semi-serial sections stained with Mallory method. The images of studied nuclei were taken with ?Leica? DM 1000 microscope and ?Leica? EC3 digital camera under 400x magnification, and analyzed by ImageJ software with A 100 grid. The statistical analysis was performed by Statistical Package for the Social Sciences software with 5% level of significance. Results. A statistically significant difference was found in the volume and surface density between principal oculomotor nucleus and trochlear nucleus, and between trochlear nucleus and abducens nucleus. No difference was found in the length density. Discussion. The results of this research match the results of studies on characteristics of vascular network of oculogyric nerve nuclei, while the comparison of vascular networks of these nuclei, substantia nigra, vestibulocochlear nuclei and precentral gyrus illustrates differences in quantitative characteristics of blood vessels in these structures. Conclusion. Blood vessels of principal oculomotor nucleus and abducens nucleus have similar dimensions and approximately the same arborization pattern, while vessels of trochlear nucleus have significantly smaller dimensions and density.

Abstract (sommario):

The topography and the main characteristics of the vestibular nuclear complex (VNC) in cattle have been studied in serially transversally cut Nissl and Gles-stained sections. By using computerized image analysis software, the cell size, the maximum and minimum diameter of the neurons of each vestibular nucleus were obtained. These parameters were statistically analyzed by comparing the cell population from different nuclei and different parts of each nucleus. Furthermore, in order to investigate the lumbo-sacral projections, the fluorescent tracer Fast Blue was injected into the L6-S1 spinal cord of three calves. Among the vestibular nuclei, the superior was the least extensive rostro-caudally, the medial was the most extensive and contained the smallest cells, the lateral showed the largest neurons, and the descending nucleus contained cells of intermediate size which decreased in a rostrocaudal direction. Concerning the lumbo-sacral projections of the bovine VNC, the present study showed that only the fibers coming from the lateral vestibular nucleus reached the L6-S1 spinal cord. The labelled neurons were most heavily concentrated in the dorsal portion of this nucleus, but scattered neurons were also observed throughout the entire extension of the nucleus. The differences between the descriptions of cattle and other species were described.

Abstract (sommario):

Study background: Fluorosis is one of the manifestations of chronic poisoning from long-term exposure to high levels of fluoride. An estimated 62 million people in 17 states in India are affected with dental and skeletal fluorosis. Objective: To evaluate the cytological morphology of exfoliated oral mucosal cells among various stages of fluorosis patients compared with controls. Design and methods: Exfoliative cytology PAP-stained smears of 21 cases of fluorosis and 21 controls subjected to morphometric analysis using image Proplus software. For the assessment parameters like maximum and minimum diameter of the nucleus, cell and perimeter of the cell and nucleus were considered. Results: An increase in maximum and minimum diameter of nucleus, perimeter of nucleus and cell in cases when compared to controls. Conclusions: Fluorosis induces oxidative stress, DNA damage and apoptosis which can be the reasons for the increase in the nuclear size and decrease in the cell size. Community dental and medical programmes should be stringently implemented in fluorosis-endemic areas, to create awareness regarding the toxic effects of fluoride to the body, especially within the oro-facial region.

Abstract (sommario):

For the identification of the lead compounds, a molecular docking tool is used. The little structure, namely Ligand, generally holds together the protein places. It describes a similar approach that utilizes to place over another three-dimensional structure of a probable drug on its prospective object sites. Given that, it was worthwhile to build a virtual library of benzimidazole derivatives to find lead structures to test against C. Albicans. The two-dimensional structure of all planned compounds was drawn by using the current version software and pass on to the software window. The energy of all three-dimensional structures was reduced by Molecular Orbital Package up to Root mean square gradient 0.001 and put aside in MDL Molfile (.Mol) format. To assess the likely potential of the Quantitative Structure-Activity Relationship models, the dataset was split into a training set comprising of 32 molecules and a test set of 8 molecules in such a way that the structural variety and an extensive range of biological action in the specific set were added. The IC50 values were transformed to pIC50 to give numerically larger data values.

Includes bibliographical references (p. 238-241).
The objective of this study is to improve quality and reliability of safety-critical software in the nuclear industry. It is accomplished by focusing on the following two areas: Formulation of a standard extensive integrated software testing strategy for safety-critical software, and Development of systematic test-based statistical software reliability quantification methodologies. The first step to improving the overall performance of software is to develop a comprehensive testing strategy, the gray box testing method. It has incorporated favorable aspects of white box and black box testing techniques. The safety-critical features of the software and feasibility of the methodology are the key drivers in determining the architecture for the testing strategy. Monte Carlo technique is applied to randomly sample inputs based on the probability density function derived from the specification of the given software. Software flowpaths accessed during testing are identified and recorded. Complete nodal coverage testing is achieved by automatic coverage checking. It is guaranteed that the most popular flowpaths of the software are tested.
The second part of the methodology is the quantification of software performance. Two Bayesian based white box reliability estimation methodologies, nodal coverage- based and flowpath coverage-based, are developed. The number of detected errors and the failure-free operations, the objective and subjective knowledge of the given software, and the testing and software structure information are systematically incorporated into both reliability estimation approaches. The concept of two error groups in terms of testability is initiated to better capture reliability features of the given software. The reliability of the tested flowpaths of the software and that of the untested flowpaths can be updated at any point during testing. Overall software reliability is calculated as a weighted average of the tested and untested parts of the software, with the probability of being visited upon next execution as the weight of each part. All of the designed testing and reliability estimation strategies are successfully implemented and automated via various software tools and demonstrated on a typical safety-critical software application.

This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.
MIDAS is the minor incident decision analysis software that acts as an advisory tool for plant decision makers and operators to analyze the available decision alternatives for resolving minor incidents. The minor incidents dealt with in this thesis include non- safety related component failure, equipment maintenance, inspection or testing. MIDAS implements the risk-informed decision analysis methodology that uses multi- attribute utility theory (MAUT) and formal decision-making models that was developed for nuclear power plants. MIDAS integrates the theory, practical models and the graphical user interfaces for analysts to quickly obtain the insight regarding the performance of decision options and driving factors. To be able to deal with the inherent diversity of scenarios and decision options, a well-defined option models and modular calculation structure were constructed in MIDAS. In addition, MIDAS provides the functions of performing sensitivity and uncertainty analyses to take into account the inherent model and parameter uncertainties in decision option evaluation. Two case studies are performed to demonstrate the application of MIDAS in nuclear power plant risk-informed incident management. The insight obtained from the analysis results of case studies reveals that for nuclear power plant incident management, risk usually is not the most important concern. Cost and external attention are usually the dominant deciding factors in decision-making. However, in fact, the safety performance of each option is reflected in terms of the cost and external attention.

Abstract (sommario):

The aim of this master theses was to evaluate the thermal-hydraulic calculation software GOTHIC for the purpose of nuclear containment safety analyses. The evaluation was performed against some of the Marviken full scale containment experiments and a comparison was also made against the two codes RELAP5 and COPTA. Models with different complexity were developed in GOTHIC and the parameters pressure, temperature and energy in different areas of the enclosure was investigated. The GOTHIC simulations in general showed a good agreement with the Marviken experimental results and had an overall better agreement then RELAP5. From the results it was possible to conclude that the developed GOTHIC model provided a good representation of the Marviken facility.

Abstract (sommario):

AbstractDNA is the molecular basis of life and would total about three meters if linearly untangled. To fit in the cell nucleus at the micrometer scale, DNA has, therefore, to fold itself into several layers of hierarchical structures, which are thought to be associated with functional compartmentalization of genomic features like genes and their regulatory elements. For this reason, understanding the mechanisms of genome folding is a major biological research problem. Studying chromatin conformation requires high computational resources and complex data analyses pipelines. In this chapter, we first present the PyGMQL software for interactive and scalable data exploration for genomic data. PyGMQL allows the user to inspect genomic datasets and design complex analysis pipelines. The software presents itself as a easy-to-use Python library and interacts seamlessly with other data analysis packages. We then use the software for the study of chromatin conformation data. We focus on the epigenetic determinants of Topologically Associating Domains (TADs), which are region of high self chromatin interaction. The results of this study highlight the existence of a “grammar of genome folding” which dictates the formation of TADs and boundaries, which is based on the CTCF insulator protein. Finally we focus on the relationship between chromatin conformation and gene expression, designing a graph representation learning model for the prediction of gene co-expression from gene topological features obtained from chromatin conformation data. We demonstrate a correlation between chromatin topology and co-expression, shedding a new light on this debated topic and providing a novel computational framework for the study of co-expression networks.

Abstract (sommario):

The aim of this work is to show the simulation of the nuclear decay of Iodine isotopes using the Mathematica software package. The nuclear decay of Iodine occurs most often during nuclear accidents in various types of nuclear facilities, during which radioactive isotopes are produced. Radioactive Iodine isotopes lead to the manifestation of harmful side effects, but with the development of science, it has been established that some of them can be used for diagnostic purposes and to detect certain types of carcinoma. The software package itself makes it possible to actively change the parameters in real time that are characteristic for the nuclear decay of Iodine. Graphically by displaying the exponential curves for decayed and non-decayed nuclei, the ratio of the number of undecayed nuclei as a function of the elapsed time can be directly calculated. The model can be implemented in classes and enables students to better understand nuclear decay in the undergraduate courses of Physics, Physics 2 and Computer simulation of physical phenomena.

Abstract (sommario):

This paper describes a software safety analysis for a software code that is installed at an Automatic Test and Interface Processor (ATIP) in a digital reactor protection system. For the ATIP software safety analysis, an overall safety analysis is at first performed over the ATIP software architecture and modules, and then a detailed safety analysis based on the software FMEA (Failure Modes and Effect Analysis) method is applied to the ATIP program. For an efficient analysis, the software FMEA is carried out based on the so-called failure-mode template extracted from the function blocks used in the function block diagram (FBD) for the ATIP software. The software safety analysis by the software FMEA, being applied to the ATIP software code which has been integrated and passed through a very rigorous system test procedure, is proven to be able to provide very valuable results (i.e., software defects) which could not be identified during various system tests.

Abstract (sommario):

Nuclear energy is an important way to solve energy shortage and pollution problems today. Therefore, China is vigorously developing nuclear energy and is facing huge demands for talents. However, nuclear engineering education has been severely hampered, particularly in its experiment aspect because of the Fukushima accident. The original sub-critical nuclear reactor at Tsinghua University (THU) was stopped, forcing students to use computers to conduct relevant nuclear simulation experiments. The emerging of supercomputers and commercial numerical simulation softwares has provided enough hardware and software support for complex calculations required in numerical simulation of nuclear reactors. Thus numerical simulation could be integrated into nuclear engineering education. With its ease of use, quick acquisition and direct visualization of results, numerical simulation can save much time and money. Besides, it is convenient to change simulation conditions which is helpful for academic research and talent development. This paper starts with THU’s nuclear engineering talent training mode, and taking the course “Advanced Nuclear Reactor Thermal Analysis” as an example, discusses the applications of numerical simulation softwares FLUENT and COBRA-TF in this course. Finally, the analysis shows that numerical simulation performs well in conceptual understanding and experimental design. It plays a significant role in nuclear engineering education, which provides an important reference for the new mode of nuclear engineering education.

Abstract (sommario):

Abstract The SARS-CoV-2 infection pandemic has led to significant loss of lives and worldwide economic disruption. The leading cause of transmission of infectious respiratory diseases is through aerosolized mucous and salivary droplets containing the virus emitted into the environment through respiratory activities. Depending on their initial size, the droplets evaporate or fall to the ground due to gravitational sedimentation. When a droplet evaporates, the droplet nucleus containing all the viruses in the original droplet remains airborne in the environment for a long duration of time. The ventilation system significantly affects the dispersion and removal of particles from the environment. Therefore, poorly ventilated indoor environments increase the risk of disease transmission. The present study modeled a ventilated small office space with two mannequins sitting across a table. It was assumed that one of the mannequins was speaking and emitting small droplets. Then the effect of the ventilation system on the droplets’ transport and dispersion was simulated. In particular, the performance of the displacement and mixing ventilation systems on particle dispersion and deposition in the room were evaluated and compared. These simulations were performed using the computational fluid dynamics (CFD) approach with Ansys-Fluent software. The Eulerian approach was used to simulate the airflow field in the room, and the Lagrangian trajectory analysis approach was used for the droplets. Experimental data of the thermal plume above the mannequin’s head were used to validate the airflow simulation results. The results showed that the displacement ventilation system has better performance (almost three times more) in removing particles from the environment than the mixing ventilation system.
