Abstract Book of the Congress on Advanced Regenerative Technologies

The growing amount of battery production will produce more substances which increase the number of harmful chemicals to the environment such as carbon dioxide, nitrogen, and sulfur dioxide. Since most Malaysians are thrown their old batteries away and replace with new batteries. The recycled batteries and revived batteries are ways to reduce the number of batteries being disposed of. Hence this study aims to determine the carbon footprint and performances of revived industrial lead-acid batteries through regeneration technology. In this study, life cycle assessment is used as a method to assess environmental impacts on which carbon footprint associated with all the stages of a batteries' life through the regeneration technology. The three processes involved in regeneration technology which charging process, discharging process, and regeneration process to evaluated the voltage, capacity, and specific gravity. From the results, the revived industrial lead-acid batteries through regeneration technology are 199.91 kgCO2-eq of a carbon footprint than recycled batteries and the discharge time of 6 batteries are increased from 3 hours 55 minutes to 5 hours after using the regeneration technology. Thus, it is confirmed the revived industrial lead-acid batteries through regeneration technology are to be used preferably in reducing the disposed of batteries.

Background. Diagnosis of osteoarthritis of the hip and knee joints, as of today, would seem to be a well-studied issue. Radiography, magnetic resonance imaging, ultrasonography - each of these methods makes it possible to make a diagnosis. At the same time, the use of new methods of treatment of osteoarthritis requires new approaches to its diagnosis.
 Objective: to develop a methodology for examining patients with osteoarthritis and aseptic necrosis of the hip and knee joints during treatment with regenerative technologies.
 Material and Methods. The material for the study was case histories of 233 patients with osteoarthritis and 58 patients with osteoarthritis of the hip and knee joints. Clinical, laboratory, and instrumental research methods were used.
 Results. The methodology of clinical examination of patients when using regenerative technologies is based on filling out quality of life questionnaires. A feature of the methodology of laboratory examination of patients with osteoarthritis and aseptic necrosis of the hip and knee joints when using regenerative technologies is oncological screening in the case of the use of biotechnological products containing MSCs, with the determination of epigenetic markers of the risk of oncogenesis in the form of miRNA.
 Conclusions. The methodology of the instrumental examination of patients with osteoarthritis is as follows: the key is an X-ray examination with the establishment of the stage of osteoarthritis according to the Kellgren-Lawrence classification and the subsequent ultrasound and MRI examination in order to assess the extent of damage to the soft tissues of the hip and knee joints, subchondral bone and paraarticular structures. In patients with aseptic necrosis of the hip and knee joints, when using regenerative technologies, the key is an MRI study followed by X-ray and ultrasound examination.

This study focuses on the actual project of rural road ‘concrete to asphalt’ pavement renovation, deeply integrating the design concept of full structure regeneration and the innovation of in-situ regeneration technology for old cement pavement. Through the life cycle assessment method, an environmental impact quantification assessment model is used. Based on the analysis of the environmental benefits of traditional pavement renovation technology (using multi-hammer crushed stone and hot mix asphalt production technology), the environmental advantages of the full-structure regeneration technology scheme are outlined, including the recycling of recycled asphalt pavement materials, application of emulsified asphalt plant mixing cold regeneration technology, and implementation of resonance crushed stone on-site regeneration technology. At the same time, sensitivity analysis methods are used to deeply analyze the sensitivity of changes in parameters such as surface and base thickness, transportation distance, and environmental factors to the overall environmental impact. The research results indicate that the optimization plan can achieve a 57.97 % reduction in total energy consumption and a 71.45 % reduction in total carbon emissions. Additionally, the recycling and utilization of RAP materials significantly reduce the demand for new mineral materials and asphalt. For a 1-kilometer road surface, mineral materials save up to 82.39 % and asphalt saves up to 27.11 %. The energy consumption and carbon emissions generated during the raw material production stage in both schemes contribute the most to the environmental impact of road construction. The analysis found that the environmental benefits of the optimization plan mainly come from the recycling of the old cement concrete pavement as the base layer after resonance crushing, as well as the use of emulsified asphalt mixture cold recycling instead of the lower layer of hot mix asphalt concrete, achieving full-scale recycling of the pavement renovation. The relevant findings provide a data foundation or the improvement and upgrading of energy-saving and emission reduction technologies in road surface renovation and offer valuable insights for future research on sustainable road surface renovation strategies.

The chapter is focused on technology of heat and moisture regeneration for ventilation systems. In the first sub-division recent progress in adsorptive technologies for air dehumidification, heating and conditioning is analyzed. In the next sub-divisions results of original researches of authors on adsorptive heat and moisture regeneration are given. The design of adsorptive heat-moisture regenerator for ventilation systems is shown. Its operation and the results of field tests are described. The technology of regeneration of low-potential heat and moisture by composite sorbent ‘silica gel – sodium sulphate' is suggested. Experimental plots of temperature, absolute and relative humidity at the inlet and the outlet of the apparatus and between cassettes with the composite are given. Correlation of flows switch-over time, airflow rate and temperature drop is stated. The relationships temperature efficiency factor vs. dimensionless temperature drop and moisture efficiency factor vs. absolute humidity dimensionless drop are derived with fair accuracy for engineering calculation. Ability of purposeful modification of the above-mentioned characteristics within broad ranges by changing the half-cycle time, the size of the granules of the adsorbent and its amount is revealed. The mathematical model and algorithm for determining the basic parameters of adsorptive regenerator operating processes are developed. The proposed algorithm involves calculating the volume of air passed through the layer of adsorptive heat-storage material, the concentration of water in the airflow at the outlet of the regenerator, the adsorption, the heat of adsorption, the final temperature of the cold air, the air temperature after mixing the cold air from the street and the warm air in the room at the warm end of the regenerator during inflow, calculation of the final concentration of water in the flow at the cold end of the regenerator, the volume of air passing through the layer of heat-accumulating material, adsorption and heat of adsorption, the final temperature of the air at the cold end of the regenerator, the air temperature after mixing of the cold air from the street and the warm air from the room at the cold end of regenerator during outflow, determining the temperature efficiency coefficient, summarized adsorption and maximal adsorption time. The correlation of air temperatures near the warm and cold end of the regenerator, as well as the temperature efficiency factors calculated according to the proposed algorithm and obtained by experimental way is confirmed. The mathematical modeling of the processes of operation of adsorption regenerators based on composites ‘silica gel – sodium sulphate' and ‘sodium acetate' in the conditions of the typical ventilation system of residential premises is carried out. The dependences of the temperature efficiency factor vs. the time of switching air flows and the velocity of air flow, as well as the temperatures of external and internal air under stationary conditions are shown. An optimal composition of composite adsorbents is stated to be 20% of silica gel and 80% of salt, that is, sodium sulphate or sodium acetate. Due to higher value of maximal adsorption composite ‘silica gel – Na2SO4' is shown to be required in half as much as compared with ‘silica gel – CH3COONa'. The results of the research can be used in the development of energy-efficient ventilation systems and devices for residential and warehouse premises.

The above article, published online on 12 July 2023, in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the journal Editor in Chief, Professor Keith Harding; and John Wiley & Sons Ltd. Following an investigation by the publisher, all parties have concluded that this article was accepted solely on the basis of a compromised peer review process. The editors have therefore decided to retract the article. The authors did not respond to our notice regarding the retraction.

A meta‐analysis was performed to assess the effects of different regenerative technologies and materials on wound healing after surgical endodontic therapy and provide a reference for surgical endodontic treatment. We searched for studies on the use of regenerative technologies and materials in surgical endodontic therapy via PubMed, MEDLINE, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Data from the time of database creation to December 2022. Two researchers independently screened the literature, extracted information based on the inclusion and exclusion criteria, and evaluated the quality of the included studies. A meta‐analysis was performed using Review Manager 5.4. The results showed that the use of regenerative technologies and materials significantly reduced wound healing failures (risk ratio [RR]: 0.30, 95% confidence intervals [CI]: 0.22–0.40, p < 0.001). Moreover, autologous platelet concentrations (APCs) (RR: 0.28, 95% CI: 0.15–0.53, p < 0.001) and collagen membrane plus bovine‐derived hydroxyapatite (RR: 0.27, 95% CI. 0.12–0.61, p = 0.002) were more effective in improving wound healing failure rates than collagen membrane alone (RR: 0.51, 95% CI: 0.20–1.25, p = 0.140). Our findings showed that APCs, as well as collagen membrane plus bovine‐derived hydroxyapatite, significantly improved wound healing after surgical endodontic therapy. In contrast, collagen membrane alone did not significantly improve wound healing outcomes. However, currently available studies vary significantly in sample size and methodologies. Hence, high‐quality randomised controlled studies with large sample sizes are necessary to validate our findings.

The prevalence of intrabony defects in patients with advanced periodontitis stages III and IV is high. These patients usually need both periodontal treatment and orthodontic therapy, including tooth movement through bone defects, to improve masticatory function, aesthetics, and overall quality of life. Clinical practice guidelines recommend periodontal regenerative surgical interventions to resolve these defects and propose initiating orthodontic tooth movement (OTM) once periodontal therapy goals have been met. Surgical interventions using various regenerative technologies like barrier membranes and enamel matrix proteins, combined or not with bone replacement grafts, have proven effective in regenerating lost periodontal tissues. However, the combination of periodontal and orthodontic treatments requires consideration of how periodontal regenerative therapies influence OTM. Studies suggest that regenerated bone may differ in density, composition, vascularity, and cellular activity, potentially affecting the speed and efficiency of OTM, and potential root resorption of moved teeth. Understanding the sequence and timing of implementing OTM after regenerative periodontal interventions is crucial due to their interlinked processes of bone resorption and formation. This narrative review aims to uncover scientific evidence regarding these combined treatments, examining the impacts of different regenerative technologies on OTM and delineating their advantages, limitations, and best practices.

Regenerative medicine is one of the new fast growing approaches to the treatment of a variety of diseases, including oncology and cardiovascular pathology, degenerative-dystrophic diseases of bones and joints, and other complex diseases including diabetes mellitus. Diabetes is regarded as one of the most dangerous non-infectious diseases in the world with a rising incidence that reaches pandemic proportions. Treatment of patients with diabetic foot ulcers including those with peripheral arterial disease is a challenging issue due to the increased risks for poor and lethal outcomes, which makes the social and economic burden of diabetes mellitus very high. The article presents state-of-the-art regenerative technologies in treatment of diabetic foot ulcers. Special attention is paid to gene and cell therapy.

Regenerative techniques have been clinically available for over a decade, but with limited success in promoting new bone, cementum and connective tissue attachment. New understanding of the tissues involved in regeneration and of the materials used to promote regeneration have led to new advances. This is the first of two articles that discusses new regenerative technologies with respect to their rationale and potential for periodontal regeneration and focuses on root conditioning, bone grafts and bone substitutes, and guided tissue regeneration.

The application of Fuzzy Delphi Method and Fuzzy AHP in lubricant regenerative technology selection

Success in achieving Indonesia’s dream of food security is faced with various significant challenges in line with climate change, which impacts sea level rise, salinity intrusion, and unpredictable weather patterns. These factors cause a decrease in rice production and salinization of rice fields in coastal areas. Regenerative technologies present a viable solution for achieving sustainable, net-zero rice farming (NZF) while enhancing resilience to climate change. This study comprehensively assesses the implementation of these technologies in Indonesian coastal regions. A bibliometric analysis and a summary of innovative agricultural methods, such as the System of Organic-Based Aerobic Rice Intensification (SOBARI), also known as IPATBO, highlight their effectiveness in improving rice yields and soil health. Results from regenerative technology demonstrations (2007–2024) show improved soil health and increased fertilizer and water efficiency, reducing inorganic inputs by 25–50% and water use by 30–40% while raising rice productivity by 25–50%. Adopting eco-friendly practices, including algal biofertilizers and compost, has further enhanced soil health. In addition, the practice of the NZF system in Indonesia will support Indonesia’s targets in reducing greenhouse gas emissions and carbon absorption.

Abstract: Digital Legacies: Humanity’s Technological Imprint interrogates how contemporary technologies accumulate into durable social, economic, and ecological formations that will outlast their inventors. Moving beyond device-centric narratives, the book conceives technology as an evolving assemblage of infrastructures, standards, labor practices, and governance regimes that inscribe values into everyday life and planetary systems. It develops an integrated framework that couples political economy with science-and-technology studies, ethics, and environmental accounting to explain how datafication, automation, and platformization co-produce value and vulnerability. Empirically, the volume synthesizes comparative case studies of digital infrastructures, open-source and open-science ecosystems, AI assurance practices, and critical infrastructure under climate stress. Methodologically, it advances a mixed toolkit—causal inference, natural experiments, sociotechnical ethnography, input–output modeling for digital supply chains, and design probes—to measure externalities across attention, privacy, and carbon-water footprints. Normatively, it argues for values-by-design and regenerative technology, articulating policy and procurement levers that align innovation with equity, accessibility, and planetary boundaries. The result is a multi-horizon roadmap—near-term guardrails, medium-term institutional reforms, and long-term public digital investments—intended for scholars, practitioners, and policymakers seeking rigorous concepts and actionable guidance to steward humane digital futures. Keywords: digital infrastructures, platform political economy, data governance, sociotechnical systems, AI assurance, interoperability standards, digital labor, open-source commons, attention and privacy externalities, climate-aligned computing, regenerative technology, values-by-design, multi-capital accounting, measurement and evaluation, policy and procurement, resilience and risk
