Combined unsupervised and semi-automated supervised analysis of flow cytometry data reveals cellular fingerprint associated with newly diagnosed pediatric type 1 diabetes

<p>Type 1 diabetes is a chronic autoimmune disease resulting in an immune-mediated loss of pancreatic &beta;-cells; however, an unbiased and reproducible profiling of type 1 diabetes-specific circulating immunome at disease onset has yet to be explored. In this study, fresh whole blood was collected from a pediatric cohort of 107 patients with new-onset type 1 diabetes, 85 relatives of patients with type 1 diabetes with 0-1 islet autoantibodies, 58 patients with celiac disease or autoimmune thyroiditis and 76 healthy controls.&nbsp;Up to 6&thinsp;mL of blood was collected from each subject into a VACUETTE&reg; TUBE 6 ml ACD-B (Greiner). Fresh whole blood underwent red blood cell lysis, was washed and stained with specific monoclonal antibodies. Fresh whole blood samples were stained with five panels of antibodies labelled as T cells, T&amp;NK cells, B cells, Tregs and DCs/monos encompassing main subsets of &nbsp;T cells, NK cells, B cells, Tregs, DCs and monocytes detected using 26 surface markers and the intracellular marker forkhead box P3 (FoxP3); for the Treg panel, intracellular staining was performed after fixation and permeabilization. Cells were acquired on a BD FACSCanto-II flow cytometer equipped with FACSDiva software (Becton Dickinson, Franklin Lakes, NJ).&nbsp;</p>

SynActJ: Easy-to-use automated analysis of synaptic activity

<p>Neuronal synapses are highly dynamic communication hubs that mediate chemical neurotransmission via the exocytic fusion and subsequent endocytic recycling of neurotransmitter-containing synaptic vesicles (SVs). Functional imaging tools allow for the direct visualization of synaptic activity by detecting action potentials, pre- or postsynaptic calcium influx, SV exo- and endocytosis, and glutamate release. Fluorescent organic dyes or synapse-targeted genetic molecular reporters, such as calcium, voltage or neurotransmitter sensors and synapto-pHluorins reveal synaptic activity by undergoing rapid changes in their fluorescence intensity upon neuronal activity on timescales of milliseconds to seconds, which typically are recorded by fast and sensitive widefield live cell microscopy.</p> <p>The analysis of the resulting time-lapse movies in the past has been performed by either manually picking individual structures, custom scripts that have not been made widely available to the scientific community, or advanced software toolboxes that are complicated to use. For the precise, unbiased and reproducible measurement of synaptic activity, it is key that the research community has access to bio-image analysis tools that are easy-to-apply and allow the automated detection of fluorescent intensity changes in active synapses.</p> <p>Here we present SynActJ (<strong>Syn</strong>aptic <strong>Act</strong>ivity in Image<strong>J</strong>), an easy-to-use fully open-source workflow that enables automated image and data analysis of synaptic activity. The workflow consists of a Fiji plugin performing the automated image analysis of active synapses in time-lapse movies via an interactive seeded watershed segmentation that can be easily adjusted and applied to a dataset in batch mode. The extracted intensity traces of each synaptic bouton are automatically processed, analyzed, and plotted using a R Shiny workflow. We validate the workflow on time-lapse images of stimulated synapses expressing the presynaptic pH reporter Synaptophysin-pHluorin or a synapse-targeted calcium sensor, Synaptophysin-RGECO. We compare the automatic workflow to manual analysis and compute calcium-influx and SV exo-/ endocytosis kinetics and other parameters for synaptic vesicle recycling under different conditions. We predict SynActJ to become an important tool for the analysis of synaptic activity and synapse properties.</p>

Combining dynamic and static analysis for automated grading SQL statements

<p><strong>Introduction</strong></p> <p>Our experiment was conducted in an undergraduate Relational Database course at the Australian National University.&nbsp;The experiment was conducted on August 10th 2018 when students enrolled in the Relational Database course started to learn relational data model and SQL.&nbsp;The experiment was carried out fully online for three weeks and a total of 393 students were enrolled.&nbsp;The students were asked to login in an online assessment platform and complete 15 exercises.&nbsp;This platform provided an SQLite environment in students browsers by compiling the SQLite C code with Emscripten.</p> <p>Students were allowed to submit and execute their answers in the form of SQL statements.&nbsp;If the execution result of the statement submitted by the student is the same as that of the reference statement,&nbsp;the online assessment platforms will return a feedback message indicating that the execution result is correct.&nbsp;During the interaction with the assessment platform,&nbsp;statements submitted by students were recorded and archived.&nbsp;Overall,&nbsp;our experiment had collected 12,899 statements submitted by students.&nbsp;To create a benchmark dataset that can be used to evaluate different grading approaches,&nbsp;we randomly selected 45 SQL statements submitted by students for each exercise,&nbsp;and asked three teaching assistants to grade them manually.&nbsp;Finally,&nbsp;we average the scores provided by the three assistants and take it as the final score of each statement.&nbsp;The dataset collected in this experiment is ready for public release.</p> <p>All experimental data are stored in Submission.sqlite,&nbsp;which is an SQLite database file.&nbsp;It is recommended to use software such as DB browser or SQLite expert to explore the database.</p> <p>&nbsp;</p> <p><strong>Datatable description</strong></p> <p>&nbsp;</p> <p><em><strong>exercises_result</strong></em></p> <p>This datatable stores the statements submitted by students.&nbsp;Based on the execution result of statement,&nbsp;statements were divided into three categories.</p> <ul> <li>noninterpretable: the statement is non-executable.</li> <li>partially correct: the execution result of statement is different from the expected result.</li> <li>correct: the execution result of the SQL statement is the same as the expected result.</li> </ul> <p>After analyzing the correct statements,&nbsp;we found that the correct set contains some statements carefully constructed by students to deceive the examination system.</p> <p>Take exercise 1 as an example,&nbsp;the task is to answer the following questions using SQL statements.</p> <p>Question:&nbsp;Assume persons who were born in the same year are the same age and there is only one youngest person&nbsp;(with no ties/draws)&nbsp;in this database,&nbsp;who is/are the second youngest person(s)&nbsp;in the database?&nbsp;List the id(s)&nbsp;of the person(s).</p> <p>The reference statement to this exercise is:</p> <pre><code class="language-sql">SELECT p.id FROM person p WHERE p.year_born = (SELECT MAX(year_born) FROM person WHERE year_born &lt;

Automated Segmentation of Large Image Datasets using Artificial Intelligence for Microstructure Characterisation and Damage Analysis

<p>Many properties of commonly used materials are driven by their microstructure, which can be influenced<br>by the composition and manufacturing processes. To optimise future materials, understanding the<br>microstructure is critically important. Here, we present two novel approaches based on artificial intelligence<br>that allow the segmentation of the phases of a microstructure for which simple numerical approaches, such<br>as thresholding, are not applicable: One is based on the nnU-Net neural network, and the other on generative<br>adversarial networks (GAN).<br>Using scanning electron microscopy images collected from large areas (~1 mm&sup2;) of dual-phase steels as a<br>case study, we demonstrate how both methods effectively segment intricate microstructural details,<br>including martensite, ferrite, and damage sites, for subsequent analysis.<br>Either method shows substantial generalizability across a range of image sizes and conditions, including<br>heat-treated microstructures with different phase configurations. The nnU-Net excels in mapping large<br>image areas. Conversely, the GAN-based method performs reliably on smaller images, providing greater<br>step-by-step control and flexibility over the segmentation process.<br>This study highlights the benefits of segmented microstructural data for various purposes, such as<br>calculating phase fractions, modelling material behaviour through finite element simulation, and<br>conducting geometrical analyses of damage sites and the local properties of their surrounding<br>microstructure.</p> <p>https://doi.org/10.1016/j.matdes.2024.113031</p>
