The inclusion of agro-industrial residues in fish diets represents a sustainable strategy for modern aquaculture. This study investigated the effects of incorporating yellow passion fruit (Passiflora edulis) residue into diets for Nile tilapia (Oreochromis niloticus) fingerlings reared in a recirculating aquaculture system (RAS) integrated with lettuce (Lactuca sativa) cultivation. Over a 60-day period, 12 tanks were used in a completely randomized design with four treatments: T1 (12% yellow passion fruit residue (PFR) with lettuce), T2 (12% PFR without lettuce), T3 (0% PFR with lettuce), and T4 (0% PFR without lettuce), each with three replicates and a stocking density of 25 fish per tank (3.75 ± 0.40 g; 5.84 ± 0.50 cm). The presence of lettuce significantly reduced ammonia levels, improving water quality. No significant differences in growth performance were observed among treatments. Antioxidant capacity was enhanced by the inclusion of 12% PFR, showing higher activities of catalase, superoxide dismutase and glutathione S-transferase. Despite a reduction in intestinal villi height in fish fed 12% PFR, no negative impacts on growth performance were identified. The study demonstrates that integrating lettuce into the RAS is effective for water treatment and that using up to 12% PFR in diets is a sustainable, functional, and promising approach for Nile tilapia, contributing to more efficient and environmentally responsible production systems.

Multilingual Template-based Automatic Item Generation for Medical Education Supported by Generative Artificial Intelligence Models ChatGPT and Claude
Authors: Kıyak Yavuz Selim , Kononowicz Andrzej A. , Górski Stanislaw
Published: December 2024

Objective: This study has two main aims. (1) To generate multiple-choice questions (MCQs) using template-based automatic item generation (AIG) in Polish and to evaluate the appropriateness of these MCQs in terms of assessing clinical reasoning skills in medical education; (2) to present a method for using artificial intelligence (AI) to generate new item models based on existing models for template-based AIG in medical education.
Methods: This was a methodological study. For the first aim, we followed Gierl’s three-step template-based AIG method to generate MCQ items in Polish. The quality of the generated MCQs were evaluated by two experts using a structured form. For the second aim, we proposed a four-step process for using a parent template in English to transform it into new templates. We implemented this method in ChatGPT and Claude by using two medical MCQ item models.
Results: Both experts found the automatically generated Polish questions clear, clinically sound, and suitable for assessing clinical reasoning. Regarding the template transformation, our findings showed that ChatGPT and Claude are able to transform item models into new models.
Conclusions: We demonstrated the successful implementation of template-based AIG in Polish for generating case-based MCQs to assess clinical reasoning skills in medical education. We also presented an AI-based method to transform item models for enhancing diversity in template-based AIG. Future research should integrate AI-generated models into AIG, evaluate their exam performance, and explore their use in various fields.
Capacitive coupling between the heart and tissue and its mathematical representation in future problems
Authors: Strzałkowski Jacek , Polak Paweł , Buchner Teodor
Published: December 2024

Objective: The objective of our study was to analyse the physics and mathematics of the coupling of cardiac sources to body volume and the impact of widespread assumptions on solutions of future electrocardiographic problems.

Methods: Based on anatomical and physiological knowledge, we discuss the physical reality of the heart boundary and formulate a new way of setting boundary conditions of future problems based on the boundary element method (BEM) within the SCIRun numerical package. This new type of boundary condition – the ”mixed” method approximating Neumann-Neumann, is compared to standard Dirichlet-Neumann conditions.

Results: By anatomical and physiological analysis, we show that there is strong evidence that mass transport, particularly charge transport through the pericardium, is negligible. On the physical ground, it should be assumed instead that the ECG signal spreads through the impermeable barrier as a displacement current that which assumes a nonzero normal component of potential gradient on the boundary. The numerical analysis shows that the new conditions give slightly better results than the standard ones. Notably, the quality of calculations is maintained, although the assumptions are different.

Conclusions: We claim that there are both physical and numerical arguments that the assumption that the normal component of a potential gradient must be zero at the heart and body border and can should be relaxed. These findings build convergence between the mathematical ideas and the physical reality of the electrolyte-filled human body. We aim to enhance the diagnostic impact of ECG-based approaches and advance our understanding of cardiac electrophysiology.

Authors: Rathod Narendra , Awasthi Kriti , Kostkiewicz Magdalena , Klimeczek Piotr , Stępień Ewa
Published: December 2024

Objectives: In order to increase diagnostic precision and efficiency in clinical settings, the goal is to assess how well sophisticated convolutional neural networks (CNNs) perform automated cardiac area recognition from chest X-ray pictures.
Methods: 496 high-resolution DICOM chest X-ray images (1024 x 1024) had been used as the dataset. Images were preprocessed, which included augmentation (e.g., scaling, rotation, contrast correction), normalization, and resizing. Metrics including Mean Squared Error (MSE) and Intersection over Union (IoU) were used to train and compare many CNN architectures (AlexNet, GoogLeNet, VGG-16, ResNet-18, and ResNet-50). The Adam optimizer was used in the training phase, with a batch size of 32 and 100 epochs. Validation was done on 96 images, and performance was measured with IoU scores and bounding box prediction accuracy.
Results: ResNet-50 outperformed the other models, with 93.2% accuracy and a mean IoU of 0.84 with very little variability. In terms of localization accuracy and training stability, the model outperformed alternative designs and demonstrated strong bounding box prediction abilities. The reliability of ResNet-50 in pinpointing specific cardiac regions under various imaging conditions is demonstrated by these results.
Conclusions: The study concludes by highlighting the revolutionary potential of deep learning in automating the detection of cardiac regions in chest X-rays. The best model turned out to be ResNet-50, which presented a big stride in incorporating AI-based solutions into diagnostic processes, especially in environments with limited resources. Combining detection and segmentation for improved diagnostic insights should be investigated in future studies.

Published: December 2024

Objectives: The HER2 receptor is often overexpressed in various cancers, particularly in breast and ovarian cancers, and this overexpression significantly contributes to the growth and spread of these tumors. Trastuzumab (Herceptin) and pertuzumab (Perjeta) are widely used humanized monoclonal antibodies (mAbs) that have shown promise in treating patients with HER2-positive breast cancer. To enhance their effectiveness, mAbs have recently been combined with chemotherapeutic agents and radionuclides. The aim of our studies was to investigate the potential therapeutic use of trastuzumab and pertuzumab labeled with the Auger electron emitter – 125I.
Methods: The radioimmunoconjugates synthesized using 125I and 131I were tested in various in vitro studies on SKOV-3 cells. These studies included tests for specificity, binding affinity, internalization, cytotoxicity (MTS assay) and confocal imaging.
Results: The results confirmed that radio-iodinated mAbs have high affinity and internalization properties in an HER2+ cell line. In contrast to trastuzumab, significant localization of iodinated pertuzumab on the cell membrane was observed. MTS assay and spheroid studies demonstrated minor toxic effects from both radio-conjugates resulting from the combination of the mAbs' immuno-toxic effect and the interaction of Auger electrons. However, [125I]I-pertuzumab exhibited higher cytotoxicity.
Conclusions: Despite high internalization, both radio-bioconjugates showed low cytotoxicity due to the lack of radionuclide localization in the cell nucleus. However, [125I]I-pertuzumab accumulated in the cell membrane, resulting in slightly higher cytotoxicity. To improve therapeutic efficacy, modifying [125I]I-trastuzumab and [125I] I-pertuzumab to transport them to the cell nucleus, e.g., using nuclear localization signal (NLS) peptides, is crucial.
VARIABILITY IN THE MUTAGENICITY OF ORGANIC POLLUTANTS ADSORBED ON THE PARTICULATE MATTER IN THE URBAN ENVIRONMENT
Authors: Jadczyk Piotr
Published: December 2024

The aim of the study was to determine differences in mutagenicity of organic pollutants adsorbedon suspended particulate matter in the city centre and its outskirts. Particulate matter was collectedusing a high-performance sampler in different parts of Wrocław in summer and winter. Organiccompounds adsorbed on the particulate matter were extracted for 8 hours in Soxhlet apparatuses.The concentration of PAHs was determined using GC-MS. Mutagenicity of samples was testedusing the Ames test. The concentrations of particulate matter suspended in the atmosphere rangedfrom 23 to 144 μg/m3, and PAHs from the EPA list adsorbed on it ranged from 8.3 to 1211.6 ng/m3.Particulate matter suspended in the atmosphere collected in different places in Wrocław insummer and winter showed mutagenic activity. This effect was greater in winter than in summer.In winter, it was greater in the city centre than on its outskirts. Activation with the S9 mix fractioncaused a decrease in the mutagenic activity of most of the tested particulate matter samples againstthe TA 98 strain. This indicates the presence of mainly direct mutagens in them. The volumesof polluted air causing a mutagenic effect on the TA 98 strain without activation by the S9 mixfraction ranged from 0.25 to 35 m3. The high sensitivity of the YG 1021 and YG 1024 strains tothe mutagenic effect of pollutants adsorbed on the tested particulate matter indicates a significantshare of nitroarenes in their mutagenic activity. The differentiation of this share depended mainlyon local and momentary conditions. The exposure of residents to the genotoxic effect of pollutantsadsorbed on particulate matter increases in winter, especially in the city centre. Supplementing thecurrently used physicochemical monitoring of air pollution with a study of the mutagenic activityof pollutants adsorbed on particulate matter would allow for the assessment of this activity and theshare of certain groups of pollutants, such as nitroarenes.

Objective: Positron emission tomography (PET) is a widely used medical imaging technique that allows for non-invasive imaging of metabolic processes. However, traditional PET scanners rely on costly inorganic scintillators that limit their accessibility, especially in light of emerging long axial field-of-view devices. The modular J-PET scanner, an innovative alternative, uses 50-cm-long plastic scintillator strips, offering a cost-effective and modular solution. In this study we develop and assess the PET data correction techniques required for quantitative image reconstruction.
Methods: We present methods for attenuation correction, random coincidence correction using the delayed time window (DTW) technique and scatter correction based on Monte Carlo simulations. Phantom studies using the NEMA IQ phantom were performed to qualitatively evaluate these corrections.
Results: The results demonstrate that our implemented corrections for attenuation and random and scattered coincidences successfully improve the uniformity of tracer distribution in homogenous volumes and significantly reduce undesired activity in cold regions. Despite limitations in sensitivity and axial resolution, the applied correction techniques effectively enhance image quality, providing promising results for future applications.
Conclusions: These findings highlight the potential of the modular J-PET system to offer affordable PET imaging and to pave the way for a total-body PET scanner based on plastic scintillators. Future work will focus on quantitative validation and the implementation of these corrections for human subject imaging.

Feline lower urinary tract diseases affect about 15 to 57% of cats, being one of the most important causes of cat visits to the veterinarian. Pandora's syndrome affects cats with lower urinary tract diseases (FLUTD), resulting in dysuria, hematuria, periuria, frequency, and stranguria. Most clinical cases of cats that present these alterations are considered as "clinically unexplained syndromes" or idiopathic, and may be related to genetic factors and epigenetic influences. Cat obstructive lower urinary tract disease can be potentially fatal because it involves a water, electrolyte and acid-base imbalance and acute kidney injury. Treatment options include clinical treatment, surgery, and changes in environmental management and behavior adaptation of cats. Clinical treatment, in many cases, is ineffective, penectomy and perineal urethrostomy surgeries are effective surgical techniques for clearing urinary flow in felines, more frequent in males, but they are associated with high rates of postoperative death (8%-22%).  Through the use of the implantation of a subcutaneous ureteral device, the urine passes through an artificial system, surgically placed, preserving the animal's ureter that is not viable. The use of this device is associated with good long-term results and a lower lethality rate. To date, no official guidelines are available in veterinary medicine to assist veterinarians in making decisions about the best treatment for these diseases, however the placement of a ureteral device remains the standard treatment of choice and is associated with the highest success rates, in addition to medications to minimize stress and management changes.

Published: December 2024

This article analyzes the relationship between death and existential anguish in the work The Hour of the Star, by Clarice Lispector, in the light of Heidegger's philosophy. The character Macabéa, marked by a lack of self-knowledge, faces death as a moment of existential revelation. Heidegger sees death as a constitutive possibility of being, which defines Dasein and the relationship of the individual with himself. Death, more than a physical end, is a condition for self-knowledge and the meaning of life. The article concludes that both Lispector and Heidegger challenge us to confront our finitude in order to find meaning in existence.

Published: December 2024

A distributed system can encompass a variety of configurations, including mainframes, personal computers, workstations, and minicomputers. The varying degrees of software flexibility and the ability to execute tasks in parallel facilitate simultaneous data processing across multiple processors. The higher the resilience of an application, the quicker it can recover after a system failure. Organisations increasingly adopt distributed computing systems as they face increased data generation and demand for enhanced application performance. These systems enable businesses to scale effectively in response to growing data volumes. Integrating additional hardware into a distributed system is generally simpler than upgrading a centralised system reliant on powerful servers. Distributed systems comprise numerous nodes that collaborate towards a common objective. This article aims to provide a comprehensive overview of distributed systems, their architectural frameworks, and essential components. This study examines how distributed systems influence the architecture and design of computer systems. The research methods consist of reviewing existing literature and analysing case studies on implementing distributed systems.

Agriculture 4.0 is a field that has spread widely around the world in this century, as it has undergone an exceptionally rapid evolution, especially when it comes to fruit recognition.Decisions about their quality are crucial to maximize profits and meet customer expectations. In the past, apples or even other fruits were based solely on visual assessments by experts, which led to errors. These old methods no longer consider the genetic evolution of apples, as they only consider their size, color, and skin imperfections. Digitizing this process saves energy and reduces costs and human error as well. Recent technological advances, which combine AI and CAO at the same time for fruit sorting, make it possible to achieve high levels of quality and meet the growing challenges of food safety on a global scale. This study proposes a machine learning-based multiclass model to improve the accuracy and efficiency of apple quality assessment. The model is trained on a large image dataset of three apple varieties: Gala, Fuji, and Golden Delicious (G.D). The model automatically classifies apples based on attributes such as color, shape, and imperfections, and evaluates their conformity. Experimental results demonstrate the effectiveness of this model, which achieves 97% accuracy in identifying apple varieties and assessing their quality. This approach significantly reduces inspection time and errors, optimizing operations in the production chain.
