Evaluation of the elemental composition and radiological density of bone tissue when replacing a metaphyseal defect with bioceramic phosphate-silicate granules (experimental study)
Authors: Rozhdestvenskiy Andrey A. , Dzuba German G. , Polonyankin Denis A.
Published: October 2024

Background: It is known that bioceramic implants containing various calcium or silicon compounds in isolation demonstrate osteoconductive effect in the replacement of post-traumatic bone defects. The combined use of these elements in single material should potentiate the organotypic filling of the bone cavity by creating favorable ion microenvironment and staged biodegradation.
AIM: To identify the correlation of radiological indicators of the density of newly formed bone tissue and content of micro- and macronutrients in a bone defect when it is replaced by bioceramics with various mass ratio of calcium phosphate and silicate.
MATERIALS AND METHODS: The study was performed on male rabbits of the “white giant” breed, which, after receiving a standardized delimited metaphysical bone defect, implants with variable ratio of calcium phosphate and calcium silicate (in proportions of 40/60, 50/50 and 60/40 wt. %) were used to replace it. The results were evaluated using multispiral computed tomography and scanning electron microscopy energy dispersive analysis with detection by the method of correlation analysis of possible connections between the obtained data.
RESULTS: Quantitative indicators of calcium and phosphorus content in bone regenerate in all groups increased mainly in the period from 30 to 60 days, and silicon content, reaching maximum amounts by the 30th day of the experiment, subsequently decreased monotonously, which showed participation of this element in the starting regenerative processes, and its decrease served as a marker of organotypic restructuring. In the elemental analysis of newly formed bone tissue during implantation of bioceramics containing phosphate and calcium silicate in the proportion of 60/40 wt. %. The highest amounts of calcium, phosphorus and silicon and the highest density of newly formed bone tissue were noted, which had direct correlation, and this pattern was observed both in the early stages (30 days) and throughout the experimental study.
CONCLUSION: Analyzing the data obtained, it can be concluded that it is advisable to study the features of the course of reparative osteogenesis depending on the ionic environment, as well as the high potential of using synthetic bioceramics in general and the prospects of using implants on the basis of phosphate-silicate composites for bone defects replacement.

Authors: Vijay Aswin , Pandian Haemanath , Elangovan Pradeep , Vijayakumari Arunkumar K. , Anantharaman Ganesh , Tajudeen Sheik M. , Raghul Rajan
Published: October 2024

Background: Many patients who visit orthopedic surgeons mainly complained of knee pain, which is often diagnosed as osteoarthritis affecting the medial compartment, whereas the lateral compartment and patello-femoral joint remain relatively unaffected.
AIM: This study aimed to establish criteria for patient selection and validate an evidence-based approach for selecting candidates for unicompartmental knee arthroplasty (UKA). Key considerations in patient selection for UKA include identifying the presence of bone-on-bone osteoarthritis in the medial compartment, ensuring a functionally normal anterior cruciate ligament, maintaining full-thickness cartilage in the lateral compartment, verifying a functionally normal medial collateral ligament, and confirming the absence of severe damage lateral to the patello-femoral joint.
MATERIALS AND METHODS: From a consecutive cohort of 390 patients with medial knee pain, preoperative radiographs of bilateral knee including anteroposterior/lateral/Rosenberg/20° valgus stress views were collected, and results were tabulated. Patients were categorized into appropriate groups. The suitability for UKA was determined based on the Oxford radiological decision aid, history, examination, and radiographic assessment including stress radiographs.
RESULTS: The Oxford radiological decision aid demonstrated 92% sensitivity and 88% specificity. According to the radiographic assessment, 49% of the knees were considered suitable for Oxford UKA (OUKA), whereas 51% were deemed unsuitable. Among the 51 knees identified as unsuitable for OUKA, 40% did not meet one radiographic criterion, 38% did not meet two criteria, 22% did not meet three criteria, and 1% did not meet four criteria.
CONCLUSION: The Oxford radiographic decision aid safely and reliably identifies the appropriate patients for meniscal-bearing UKA and achieves good results in this population. The widespread use of this radiological decision aid should improve the results of UKA.

Published: October 2024

Background: This article describes the protocol for the purification of xenogenic bone matrix tested by a team of authors in the article «Determining the effectiveness of a xenogeneic bone matrix decellularization protocol in in vitro and in vivo studies» (the test results were described in the journal N.N. Priorov Journal of Traumatology and Orthopedics. 2023;30(4):431–443, doi: https://doi.org/10.17816/vto622849).
AIM: To conduct a comparative analysis of methods of physical and chemical purification of xenogeneic spongy bone tissue by tomographic and morphological studies.
MATERIALS AND METHODS: Xenogenic bovine femoral spongiosa tissue was fragmented to the size of 10×10×10 mm and treated with water, hypertonic, hypotonic, hypotonic solutions, and 3% or 6% hydrogen peroxide solution in various combinations. Deep secondary purification with organic solvents or supercritical fluid extraction was then applied, followed by 1H NMR to determine traces of reagents. The efficiency of the optimal protocol was determined by histologic and tomographic studies with calculation of the purification factor by densitometric indices.
RESULTS: In accordance with the purification coefficient calculated by densitometric indicators, the intertrabecular space of bone tissue after exposure to flowing water and hypo- and hypertonic solutions followed by cleaning with a 3% H2O2 solution is not sufficiently purified; histological analysis showed the presence of 0 to 60% osteocytes for different cleaning protocols. When replaced with a 6% H2O2 solution, the purification coefficient was higher, but bone destruction was observed. Additional deep purification allows a high purification rate while preserving the structure, but when organic solvents are used, their traces are detected in the matrix; therefore, the use of supercritical fluid extraction is more effective.
CONCLUSION: The sequential use of flowing water, 0.5% NaCl solution, 3% H2O2 solution followed by sc-CO2 treatment is an effective protocol for the purification of xenogeneic spongy bone tissue.

Published: October 2024

Nanotechnology-enhanced tissue engineering represents groundbreaking shift of reconstructive abdominal surgery and in mesh integration and vascularized composite allotransplantation (VCA). We explore nanomaterial’s role in this review and investigate how it improves biocompatibility, strength, and functional performance of synthetic meshes as well as their impact on reducing complications such as mesh rejection and infection. Current data suggests nanoscale modifications to mesh surfaces promote cellular adhesion and angiogenesis, reduce inflammatory responses, and is paradigm shift from traditional approaches. Advancements in nanotechnology can revolutionize VCA by enhancing tissue regeneration and improve vascularization and reducing immunosuppressive needs post-transplantation. Statistics reveal complications from conventional mesh repairs such as hernia recurrence occur in up to 30% of cases. Early trials using nano meshes have demonstrated a reduction in recurrence rates to below 15%. Nanotechnology’s integration into VCA could address critical limitations of donor tissue viability with experimental models showing improved graft survival and function. We synthesize latest clinical studies, experimental trials, and meta-analyses to evaluate nanotechnology's current efficacy and future potential in abdominal reconstructive surgery. While promising these innovations are still nascent, requiring further large-scale clinical validation. We aim to provide comprehensive overview of the most recent advancements and discuss current limitations and future research directions for integrating nanotechnology into reconstructive abdominal surgery while focusing on mesh and VCA applications.

Authors: Thounaojam Monika , S. Radha M. , N. Vanitha
Published: October 2024

Background: Social media has grown extensively among the adolescent population. However, excessive use at bedtime is reported to affect their quality of sleep. Sleep is very important for the normal growth and development of a child; meanwhile, inadequate sleep poses numerous health risks. The study was conducted with the objective to assess the impact of bedtime social media usage on the quality of sleep among adolescents and to find the relationship with socio-demographic variables.
Methods: A descriptive survey was conducted for the study. Non-probability purposive sampling technique along with inclusion and exclusion criteria was used to select 150 adolescents. Socio-demographic data and Pittsburgh sleep quality index (PSQI) were administered to assess bedtime social media use and quality of sleep.
Results: There was a weak positive correlation (r=0.262) between bedtime social media use and quality of sleep which is statistically significant (p=0.001). A statistically significant association was found between quality of sleep and standard (p=0.003), usual bedtime for the past month (p=0.000), hours slept during weekdays (p=0.000), and hours of social media use at bedtime (p=0.000).
Conclusions: Regardless of the health risk posed by inadequate sleep due to overindulgence of social media at bedtime, its exploitation among adolescents is still on the rise. Therefore, the findings suggest that it is very crucial to give awareness and education regarding healthy use of social media and good quality of sleep in order to live a healthy and productive life in the future.

Published: October 2024

There is a dearth of interoperability between apps, data streams, and predictability in the healthcare industry for a significant amount of the data generated by multiple digital ecosystems. Real-time data streams can be derived as meaningful and scalable enough to enable real-time healthcare predictive analytics thanks to the new technology approach in distributed messaging and Blockchain, which has become a fundamental component of many healthcare technology stacks. Additionally, absorbing data streams from multiple sources from patterns of data can enhance models that are hampered by complex and lengthy analyses by raising the level of prediction and accuracy. Improved responses, lowered availability requirements, and unified predictive modeling will speed up healthcare interoperability and, in turn, improve diagnosis accuracy, move evidence-based medicine (EBM) in the right direction, and produce other positive effects on healthcare that improve best results and quality.

The ideological status of fantasy: historical and philosophical aspects
Authors:   Moscow Pedagogical State University, Unukaev Gleb A.
Published: October 2024

The author examines the influence of the phenomenon of fantasy on individuals and society through the lens of its historical emergence and development. The author argues for the necessity and importance of analysing this phenomenon, as it has deep historical roots and context, and has a profound impact on contemporary individuals and society as a whole. The structure of mythology's influence on people and the transmission of culture is, according to the author, closely linked to the nature of creativity and social adaptation, as demonstrated by examples from both ancient and Norse myths. The author shows that the development and formation of fantasy as a part of culture takes place within, but is not limited to, these historical events and processes. Fantasy absorbs the rediscovered romance of the Middle Ages and the influence of the preceding genre of science fiction. The spirit of the age demands a revision of the axiological foundations of modern humanity, based on the creative functionality of past meanings. This allows for a discussion of the close connection between fantasy and the processes of individual development and solidarity, as well as the formation of the individual as a subject. The author concludes that fantasy is a new response, a consolation and a benefit rooted in myth, fairy tales and medieval romance.

Published: October 2024

Background: Aluminium (Al) stress is among the prime limitations of crop production including Lentil, in acidic soils as Al solubilizes into phytotoxic forms at low pH causing root growth inhibition, minimizing plant-vigor and yield. The current study was performed to identify the Al tolerant RILs based on root-regrowth studies, short term growth culture and organic acid exudation in reaction to Al toxicity under hydroponics. Methods: The study involved screening for Al toxicity tolerance in recombinant inbred lines (RILs) population of lentil through root re-growth studies, short term growth response method under hydroponics treated with toxic concentration of Al (148 µM), organic acid exudation using HPLC and correlation analysis among the traits. Result: ANOVA for root and shoot traits revealed presence of highly significant genotypic differences for all the traits. High GCV along with high H2bs and GA% were observed for the traits revealing the influence of additive genes and suggested reliable selection of these traits for Al toxicity tolerance. Citric acid was exudated in highest amount in all the genotypes and was positively and significantly correlated with RRG. Based on the hydroponics study and organic acid exudation, RILs identified as tolerant were LRIL-10, LRIL-37, LRIL-68, LRIL-96, LRIL-97, LRIL-113, LRIL-125, LRIL-133, LRIL-143, LRIL-144 and LRIL-148. With further evaluation, these RILs may serve as important Al toxicity tolerant varieties suitable for acidic soil conditions. Also, these lines may serve as donors of Al toxicity loci and mapping of Al tolerance genes.

Published: October 2024

Purpose: To consider the design features of single-blade and double-blade arrows, as well as double-blade arrows with flexible blades, the operating conditions of tram switches when placing tram nodes on the line and on the territory of tram parks. Methods: The analysis of the main operational and economic indicators of switches is carried out, taking into account the advantages and disadvantages of various types of arrow designs of the tram industry in St. Petersburg, including those requiring speed limits of tram cars when moving along the arrows. Results: Recommendations have been developed for the use of switches of various designs, depending on their operating conditions, load stress, speed of movement of rolling stock for safe passage along them, placement on the line on a combined, independent or separate track and in tram fleets, taking into account the complexity of replacing worn parts, as well as the need to ensure the required track development in the presence of cramped conditions. The proposed recommendations will allow the use of switches in accordance with modern requirements for tram crossings, which ensure comfortable movement of passengers. Practical importance: Considering the fact that economic indicators, along with the technical characteristics of switch designs and operational capabilities of track sections, are one of the main criteria for evaluating decision-making, it is proposed to use methodology for accounting for economic indicators based on determining the cost of the life cycle to justify the effectiveness of using a particular type of switch in the design and operation of tramways paths in specific conditions.

Published: October 2024

This article specifically examines the resolution of the core values of wasathiyah Islam as an effort to counter the movement of religious radicalism, both directly in the community and in the digital space. Wasathiyah Islam as a form of rahmatan lil 'alamin is an understanding that needs to be disseminated in order to achieve harmony, security, and peace in religion. This article uses a qualitative method of descriptive analysis with library research steps sourced from books, journals, and other supporting data. The article argues that the nature of the value of wasathiyah Islam that consists of: Rahamutiyah (the flow and outpouring of affection without limitation, without discrimination and without pause), Insaniyah (humanity), 'Adliyyah (fairness), Mubadalah (equality), Maslahah (benefit), Mu'ahadah Wathaniyah (maintaining national ties), Dusturiyah (obeying the rules that have been agreed upon, for example the laws that apply in a country), Tasamuh (tolerance), and 'Urfiyah (not rejecting customs/traditions, and can even make them a component of the source of law) needs to be encouraged in various spaces of life, including on the internet. That way, the future of Indonesian Muslims will be protected from exposure to religious radicalism.
On the Salient Limits of Strings of Assembly Theory
Authors: Bieniawski Wawrzyniec , Masierak Piotr , Łukaszyk Szymon , Tomski Andrzej
Published: October 2024

We consider the formation of strings of any natural radix b within the framework of assembly theory. In particular, we show that the upper bound of the assembly index depends on the radix b both quantitatively and qualitatively, and the longest length N of a string that has the assembly index of N-k is given by N(N-k)=b2+b+3k-2 for k={1,2,3}. We also provide two particular forms of such strings. For k=1 such odd length strings are nearly balanced and there are four such different strings if b=2 and seventy-two if b=3. Since these results are valid also for b=1, assembly theory subsumes information theory.

Published: October 2024

The bioherbicidal potential of four essential oils (EOs) from Mediterranean species of Thymus sp. pl.: Thymus algeriensis Boiss. et Reut., T. ciliatus Desf. subspecies coloratus (Boiss. et Reut.) Batt., T. vulgaris L., ecotype Fasano and T. vulgaris L. var. Varico was investigated to identify new sources of biomolecules. In vivo assays were carried out to assess the effect of the EOs on pre and post-emergence of two weed species: Lolium perenne L. and Amaranthus retroflexus L.. Four concentrations of EO emulsions (500, 750, 1000 and 2000 µl/100 mL) were applied. All the EOs expressed an important bioherbicidal activity against the target species. A total inhibition of seed germination was displayed at 2000 µl whereas a potent effec-tiveness was achieved even at 500 µl. On the contrary, for post-emergence experiments, L. perenne showed resistance to the EOs while A. retroflexus was highly sensitive, arguing a selectivity of the EOs. Bioassays were also performed on the model plant Arabidopsis thaliana (L.) Heynh, for a better understanding of the structural modifications induced by the EOs. The root system of EO-treated A. thaliana seedlings was highly damaged.
MicroRNA Profiling of PRELI-Modulated Exosomes and Effects on Hepatic Cancer Stem Cells
Authors: Kim Boyong
Published: October 2024

Background/Objectives: The increasing incidence and mortality rates of liver cancer have heightened the demand for the development of effective anticancer drugs with minimal side effects. In this study, the roles of exosomes derived from liver cancer stem cells (LCSCs) with PRELI (Protein of Relevant Evolutionary and Lymphoid Interest) modulation, and their miRNAs were investigated to explore the therapeutic for liver cancer. The purpose of this study is to identify a more effective and less toxic anticancer agent beyond the well-known Notch, p51, and Hippo signaling pathways, and to specifically propose the potential of PRELI-induced exosomes as an anticancer therapeutic candidate. Methods: Various techniques, such as miRNA profiling, flow cytometry, western blotting, and immunocytochemistry, were used to evaluate the effects of ex-osomes under PRELI up- and downregulation. Results: PRELI upregulation altered expression levels of miRNAs, including hsa-miR-378a-3p (involved in stem-like properties), hsa-miR-25-3p (contributing to cell proliferation), and hsa-miR-423-3p (driving invasiveness). Exosomes with downregulated PRELI inhibited AKT/mTORC1 signaling, while this signaling pathway was ac-tivated in LCSCs transfected with the candidate miRNAs. Under PRELI up-regulation, exosomes showed increased surface marker expression, promoting cancer progression. Conclusions: The modulation of PRELI in LCSCs affects miRNA expression significantly, revealing candidate miRNA targets for liver cancer treatment. Exosomes with PRELI down-regulation show potential as a novel therapeutic strategy.

Authors: Kosior Dominik , Wiertel-Pochopień Agata , Morga Maria , Witkowski Łukasz , Zawala Jan
Published: October 2024

In recent decades, numerous studies have focused on finding environmentally friendly substitutes for commonly used petrochemical–based compounds. This paper explores the potential use of poly-L-lysine/rhamnolipids and poly-L-glutamic acid/ethyl lauroyl arginate mixtures, for foam formation and stabilization. Two complementary methods were employed to investigate the synergistic and antagonistic effects of these mixed polyelectrolyte/surfactant systems: (1) the thinning and rupture of thin foam films formed under dynamic conditions were monitored using a dynamic fluid-film interferometer (DFI), and (2) foamability tests were conducted using a standard dynamic foam analyzer (DFA). The results demonstrated that adding polyelectrolyte to an oppositely charged surfactant primarily induces a synergistic effect, enhancing foaming properties and extending foam lifetime. Furthermore, interferometric methods confirmed improved stability and slower drainage of thin foam films in systems containing synthetic polypeptides.

This scoping review aims to systematically examine and analyse the available literature on pure total talar dislocation, focusing on its epidemiology, clinical presentation, imaging techniques, surgical options, rehabilitation protocols, and complications. Following the PRISMA-ScR guidelines, a comprehensive search was conducted across PubMed, Web of Science, and Scopus databases. The search yielded 185 articles, from which 30 met the inclusion criteria, focusing on pure total talar dislocation without fractures. Data from each study were extracted, including patient demographics, injury characteristics, treatment methods, and outcomes. A total of 30 articles were included in this review after screening and quality assessment by five independent reviewers. The studies included case reports, case series, and reviews. Despite the heterogeneity of available studies, key findings suggested that early reduction, careful wound management, and soft tissue preservation are crucial in minimising complications such as avascular necrosis (AVN), post-traumatic arthritis, and infection. Long-term outcomes varied, and the risk of AVN remained high, particularly in cases with compromised blood supply to the talus. Pure total talar dislocation is a rare and challenging condition with no established management protocol. While talar reimplantation and joint fixation offer promising outcomes in preserving function, the risk of complications, particularly AVN, remains significant. Further research is needed to standardise treatment protocols and improve clinical outcomes for this rare but severe injury.

In the realm of digitalization, data play a crucial role across various scientific fields, from physics to engineering. Analyzing data with advanced technologies like artificial intelligence enhances en-gineers' ability to make informed judgments on product quality. This study aligns with the digital-ization trend by implementing formula generation, generalization, and optimization using genetic algorithms and three machine learning approaches: support vector regression, Gaussian process regression, and artificial neural networks, on a grinding process dataset from a previous study on UNS S34700 steel. The study introduces new approaches by considering three different grinding wheels and four cooling and lubrication solutions as influential process parameters, previously considered qualitative and fixed in earlier literature. Additionally, seven different depths of cut were implemented to measure surface roughness and grinding forces (tangential and normal). Qualitative data were encoded into quantitative data using standard techniques. By enhancing genetic algorithm optimization, a relational formula with 25 coefficients was developed to describe the relationship between input parameters and outputs. Three machine learning algorithms were evaluated for predicting the relationship between predictors and responses. The flexibility and scalability of these methods, combined with the relational formula, provide a sophisticated ap-proach for future expansions. The formula evaluation achieved around 85% accuracy for surface roughness and 90% for grinding forces. In machine learning approaches, the GPR method reached model stability with an R² of around 0.98 and a mean accuracy of 93%, while the ANN reached an R² of around 0.96 and a mean accuracy of 90%. This shows that machine learning approaches are more suitable than formula generalization. The scalability and flexibility of machine learning help generalize with more data variety, while the formula evaluation only accepted current data sets. Furthermore, ML methods achieve high accuracy and are suitable for predicting future data, aligning with digitalization and trend prediction.

Liver disease can significantly impact life expectancy, making early diagnosis and therapeutic intervention critical challenges in medical care. Imaging diagnostics play a crucial role in diagnosing and managing liver diseases. Recently, the application of artificial intelligence (AI) in medical imaging analysis has become indispensable for healthcare. AI, trained on vast datasets of medical images, has sometimes demonstrated diagnostic accuracy that surpasses human experts. AI-assisted imaging diagnostics are expected to contribute significantly to the standardization of diagnostic quality. Furthermore, AI has the potential to identify image features imperceptible to humans, thereby playing an essential role in clinical decision-making. This capability enables physicians to formulate more accurate diagnoses and develop effective treatment strategies, ultimately improving patient outcomes. Additionally, AI is anticipated to become a powerful tool in personalized medicine. By integrating individual patient imaging data with clinical information, AI can propose optimal treatment plans, making it an essential component in providing the most appropriate care for each patient. Current reports highlight the advantages of AI in managing liver diseases. As AI technology continues to evolve, it is expected to further advance personalized diagnostics and treatments, contributing to overall improvements in healthcare quality.

The aim of this study involved the optimisation of the processes of laser cladding using statistical tools to improve the mechanical properties of the clad WC/Co/Ni deposits and to obtain the required weld for practical applications. The effect of laser cladding parameters on wear properties of welds was determined by using orthogonal array tests and analysis of variance. It was found that Co content, Ni content, laser power and scanning height were significant factors affecting WC/Co/Ni welds. In addition, the significant factor in response surface method was used to construct the response surface model based on the data from the orthogonal array experiment that was designed by Taguchi. The experimental results showed that a look at the microstructural evolution shows that white initially precipitated carbides are present, grey areas are WC mixed with Co and Ni compounds, meanwhile, the wear structure is an internal extension of unmelted WC, with greater plastic deformation in the Co-based alloys, and to a lesser extent in the Ni-based alloys, and even smaller plastic deformation in the WC-Co-Ni alloys. By adding nickel/cobalt alloys, the composite coating extension is seen to have good anti-wear performance. Based on the regression model of the wear by laser cladding, a pairwise interaction model in RSM was developed, which was further deepened to develop a three-dimensional contour pairwise interaction model of the wear behaviour. The results show that the predicted values of the RSM for wear performance are very close to the experimental data, which proves the effectiveness of the Taguchi design-based RSM in improving the mechanical properties of laser cladding.

The reliable operation of power systems depends on rapid fault detection to trigger protection mechanisms and prevent further damage. Machine Learning-based fault detection systems have gained prominence for their superior performance. These automated systems can assist operators by highlighting anomalies and faults, providing a robust framework for improving Situation Awareness. However, existing approaches predominantly rely on monolithic models, which struggle with adapting to changing data, handling imbalanced datasets, and capturing patterns in noisy environments. To overcome these challenges, this study explores the potential of Multiple Classifier System (MCS) approaches. The results demonstrate that ensemble methods generally outperform single models, with dynamic approaches like META-DES showing remarkable resilience to noise. These findings highlight the importance of model diversity and ensemble strategies in improving fault classification accuracy under real-world, noisy conditions. This research emphasizes the potential of MCS techniques as a robust solution for enhancing the reliability of fault detection systems.
