Stem cells derived from human exfoliated deciduous teeth (SHED) have emerged as an alternative stem cell source for cell therapy and regenerative medicine because they are readily available, pose fewer ethical concerns, and have low immunogenicity and tumourigenicity. SHED offer a number of advantages over other dental stem cells, including a high proliferation rate with the potential to differentiate into multiple developmental lineages. The therapeutic effects of SHED are mediated by multiple mechanisms, including immunomodulation, angiogenesis, neurogenesis, osteogenesis, and adipogenesis. In recent years, there is ample evidence that the mechanism of action of SHED is mainly due to its paracrine action, releasing a wide range of soluble factors such as cytokines, chemokines, and trophic factors (also known as ‘secretome’) into the local tissue microenvironment to promote tissue survival and recovery. This review provides an overview of the secretome derived from SHED and highlights the bioactive molecules involved in tissue regeneration and their potential applications in regenerative medicine.

Food safety and security are top priorities for consumers and the food industry alike. Despite strict standards and criteria for food production processes, the potential for food-borne diseases due to improper handling and processing is always present. This has led to an urgent need for solutions that can ensure the safety of packaged foods. Therefore, this paper reviews intelligent packaging, which employs non-toxic and environmentally friendly packaging with superior bioactive materials that has emerged as a promising solution. This review was prepared based on several online libraries and databases from 2008 to 2022. By incorporating halal bioactive materials into the packaging system, it becomes possible to interact with the contents and surrounding environment of halal food products, helping preserve them for longer periods. One particularly promising avenue of research is the use of natural colourants as halal bioactive materials. These colourants possess excellent chemical, thermal, and physical stabilities, along with antioxidant and antimicrobial properties, making them ideal candidates for use in intelligent indicators that can detect food blemishes and prevent pathogenic spoilage. However, despite the potential of this technology, further research and development are needed to promote commercial applications and market development. With continued efforts to explore the full potential of natural colourants as halal bioactive materials, we can meet the increasing demand for food safety and security, helping to ensure that consumers have access to high-quality, safe, and nutritious foods.

In the realm of dental tissue regeneration research, various constraints exist such as the potential variance in cell quality, potency arising from differences in donor tissue and tissue microenvironment, the difficulties associated with sustaining long-term and large-scale cell expansion while preserving stemness and therapeutic attributes, as well as the need for extensive investigation into the enduring safety and effectiveness in clinical settings. The adoption of artificial intelligence (AI) technologies has been suggested as a means to tackle these challenges. This is because, tissue regeneration research could be advanced through the use of diagnostic systems that incorporate mining methods such as neural networks (NN), fuzzy, predictive modeling, genetic algorithms, machine learning (ML), cluster analysis, and decision trees. This article seeks to offer foundational insights into a subset of AI referred to as artificial neural networks (ANNs) and assess their potential applications as essential decision-making support tools in the field of dentistry, with a particular focus on tissue engineering research. Although ANNs may initially appear complex and resource intensive, they have proven to be effective in laboratory and therapeutic settings. This expert system can be trained using clinical data alone, enabling their deployment in situations where rule-based decision-making is impractical. As ANNs progress further, it is likely to play a significant role in revolutionizing dental tissue regeneration research, providing promising results in streamlining dental procedures and improving patient outcomes in the clinical setting.

The increasing demand for halal food products is driven by the growing Muslim population and rising awareness of halal practices, both among Muslims and non-Muslims. This study aims to provide a systematic overview of halal standards and the competitiveness of the halal food industry, spanning the period from 2013 to 2024. A total of 364 published articles were reviewed using Systematic Literature Review (SLR) and bibliometric analysis methods. The key findings highlight the evolving landscape of halal certification standards, the interconnectedness of halal standards with business competitiveness, and the global competitiveness of halal food industries, with a particular focus on countries such as Malaysia, Indonesia, and Turkiye. The study provides practical insights for policymakers and industry leaders looking to enhance the halal food industry's global competitiveness. Limitations include the exclusion of some regions and the rapidly evolving nature of halal certification systems, while recommendations include further research into halal certification’s role in the global supply chain and business performance.

Background/Objectives: Excitotoxicity, primarily caused by excessive glutamate signaling, is a significant contributor to the aetiology of several neurological disorders. Docosahexaenoic acid (DHA), a long-chain omega-3 polyunsaturated fatty acid, is known for its neuroprotective properties, including antioxidants and anti-inflammatory effects. However, the existing literature has not sufficiently reviewed its specific role in glutamate-induced excitotoxicity. This systematic review aimed to provide comprehensive information from the literature on the neuroprotective effects of DHA in models of glutamate-induced neurotoxicity. Methods: A systematic search was conducted in the Cochrane Library, Scopus, Web of Science, PubMed, ScienceDirect, and Google Scholar, following PRISMA 2020 guidelines. The following keywords were used: DHA OR docosahexaenoic acid AND excitotoxicity OR glutamate-induced excitotoxicity OR glutamate-induced neurotoxicity. A total of 475 articles were screened, and 13 original articles published between 2003 and 2025 were included for data extraction. These studies included nine in vivo animal studies, three ex vivo studies, and one in vitro study. The risk of bias was assessed using SYRCLE’s methodology. Results: Our findings demonstrate that DHA provides substantial neuroprotection against excitotoxicity through antioxidative, anti-inflammatory, and anti-apoptotic mechanisms. Furthermore, DHA enhances neuronal function and cognitive performance by modulating neurotransmitter levels and glutamate-related signaling pathways. Despite these positive outcomes, heterogeneity across studies suggests that the neuroprotective properties of DHA may be affected by various parameters, such as the source of DHA, treatment dose and duration, age and experimental design. Conclusions: Although previous studies have demonstrated the benefits of DHA in preclinical and clinical settings of neurological disorders, further clinical studies focusing on the modulation of excitotoxicity by DHA are needed to validate its translational efficacy and therapeutic significance.
