Background

This study investigates the physicochemical properties of candlenut (Aleurites moluccana) and daikon radish (Raphanus sativus L.) to explore their potential as natural healing remedies as practised by local communities in Malaysia. Both plants have been used in traditional medicine, but there is limited research on their bioactive compounds and how their characteristics contribute to anti-inflammatory effects.

Results

Colour analysis for fresh candlenut exhibited significantly higher L* value (67.70 ± 0.11) compared to its extract (43.21 ± 0.00). This indicated that fresh candlenut had more whitish hue. Likewise, fresh daikon radish showed more whitish hue compared to its extract. Yellowish hue was more pronounced in fresh candlenut (25.46 ± 2.92) compared to its extract (0.45 ± 0.02). Hydroxyl (O–H), alkenyl (C=C), iso-dimethyl (–CH₃), and oxygen-bonded (C–O) functional groups were found in both samples using the FTIR method. Significantly higher tannin content was found in candlenut (91.77 ± 12.18 mg/L), compared to daikon radish (2.13 ± 3.00 mg/L). Similarly, alkaloid concentrations were significantly higher in candlenut (10.30 ± 0.59 mg/L) than in daikon radish (3.56 ± 0.12 mg/L). Phenolic analysis using HPLC identified gallic acid concentrations of 273.43 ± 17.23 mg/L in candlenut and 27.39 ± 20.39 mg/L in daikon radish. Daikon radish detected vanillic acid (28.43 ± 11.92 mg/L) and p-coumaric acid (3.04 ± 0.12 mg/L), which was not detected in candlenut.

Conclusions

These results suggested that candlenut contains higher alkaloids, tannins and gallic acid compared to daikon radish. Vanillic acid and p-coumaric acid, however, were detected in daikon radish only. All three phenolic acids can act as an antioxidant. However, gallic acid was found in higher proportion in candlenut; hence, it has higher potential against oxidative damage condition. This research supports the traditional use of these plants in managing inflammatory conditions and highlights their potential for nutraceutical applications. It may be a useful to eliminate trigger in inflammatory with interaction with receptors. These interactions occur in NF-κB signalling in inflammation pathway usually, and its dysregulation is an important factor for many inflammatory-related diseases such as asthma, atherosclerosis, gout, diabetes, cancer and many more.

Background

Organ inflammatory diseases remain a major contributor to global morbidity and mortality, yet current therapies fail to adequately prevent tissue damage progression. Stem cell therapy offers immunomodulatory and regenerative benefits, but its effectiveness varies substantially across administration routes, creating uncertainty in optimal clinical selection.

Main body

This systematic literature review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to compare administration routes of stem cell therapy and its derivatives for organ inflammation. Searches of Scopus, Web of Science, and PubMed databases up to 4 July 2025 identified 790 records; after screening and quality appraisal with Mixed Methods Appraisal Tool (MMAT) 2018, 57 empirical studies published from 2015 onward were included, covering 17 administration routes evaluated against 10 predefined effectiveness and safety domains. Qualitative findings were converted into an ordinal 1–3 scoring system and visualized in a heatmap to enable semiquantitative comparison across routes. Invasive routes such as intramyocardial, intra-arterial, portal vein, intrathecal, and intraparenchymal delivery consistently achieved the highest composite scores for target organ retention, homing, and functional repair, but were penalized for procedure-related risks and feasibility. Noninvasive routes (intravenous, intranasal, nebulized, oral, and sublingual/topical) showed lower target retention but more favorable safety, practicality, and suitability for repeated dosing. Across indications, intraperitoneal delivery tended to outperform intravenous administration for abdominal diseases, whereas intranasal and nebulized approaches were particularly promising for nose-to-brain and lung targeting using relatively low doses.

Conclusion

Stem cell therapy effectiveness is route-specific and reflects trade-offs between target organ delivery and safety–feasibility profiles. The semiquantitative synthesis presented here supports a “route-specific optimization” framework to guide personalized selection of administration routes and to prioritize future translational and clinical research.

Background

Accurate long-term tracking of transplanted stem cells is essential for evaluating therapeutic efficacy, biodistribution, and safety in regenerative medicine. Conventional imaging and molecular tracing methods often lack the sensitivity or temporal stability required for quantifying small residual cell populations over extended periods. Carbon-14 (C-14), a long-lived radioactive isotope, offers a unique opportunity to overcome these limitations by enabling durable and quantitative labeling of stem cells.

Main body

C-14 labeling provides an inheritable molecular marker that is stably incorporated into nucleic acids and other macromolecules, permitting attomole-level detection using accelerator mass spectrometry (AMS). This analytical sensitivity enables reliable quantification of fewer than 100 transplanted cells within complex host tissues—an order of magnitude beyond the detection limits of polymerase chain reaction (PCR) and other conventional assays. Through AMS-based analysis of time-resolved tissue samples, C-14 tracing supports precise assessment of cell survival, migration, engraftment, and long-term persistence. The approach further allows the identification of adverse outcomes such as ectopic engraftment, uncontrolled proliferation, or tumorigenicity by detecting abnormal expansion or mislocalization of labeled cell populations. Collectively, C-14-based tracking provides both quantitative accuracy and temporal resolution suitable for rigorous preclinical evaluation of stem cell therapies.

Conclusion

C-14 tracing represents a powerful analytical platform capable of transforming cell tracking strategies in regenerative medicine. Its unparalleled sensitivity and long-term detection capability offer clear advantages for studying stem cell fate, optimizing therapeutic protocols, and strengthening safety assessments. Continued methodological refinement and broader standardization will be crucial for translating this technology into wider preclinical and clinical use.

Background

Opuntia cactus, or prickly pear, is a good source of bioactive compounds, especially betalains that have high antioxidant activity and play an important role in human health. However, despite their nutritional and functional benefits, these compounds are highly sensitive to environmental conditions, leading to reduced stability and bioactivity during processing and digestion.

Scope

To overcome the stability challenges, double emulsions (W₁/O/W₂) have emerged as an innovative encapsulation and delivery system for bioactive compounds. This review explores the structural characteristics of double emulsions, their encapsulation mechanisms, and models describing release kinetics under digestive conditions. Factors influencing emulsion stability—including emulsifier type, droplet size, phase ratio, and processing conditions—are critically discussed. Studies demonstrate that double emulsions can significantly enhance the stability, bioaccessibility, and controlled release of sensitive compounds such as betalains, while maintaining desirable sensory and functional properties. Their successful incorporation into various food matrices, including beverages, dairy, and bakery products, has resulted in improved nutritional profiles, antioxidant retention, and extended shelf life. Additionally, industrial scalability and formulation challenges are examined, emphasizing the importance of optimizing processing parameters and ensuring consumer acceptability.

Conclusion

Double emulsions provide a novel approach to improve the stability and delivery of bioactive ingredients in functional foods. Future research and development should focus on optimizing their design and functionality, enabling widespread application across the food industry and healthier food products.

Graphical abstract

Background

Lung injury is a frequent adverse effect of chronic thinner exposure. The purpose of this research was to assess whether or not chamomile tea may protect against thinner-induced lung damage and its potential mechanisms. Thirty adult male Wistar rats were randomly assigned into five equal groups; the first three were control, vehicle, and chamomile tea (400 mg/kg bw), while the last two groups were inhaled thinner at a dosage of 4500 ppm, four hours/day, six days/week, with or without chamomile tea, daily for eight weeks. Lung tissues were taken for biochemical and immunohistochemical investigations at the end of intervention period.

Results

Thinner exposure resulted in significant increases in inflammatory cytokines (TNF-α, IL-1, IL-6), inflammatory mediators (COX2,NF-κβ), adhesion molecules (ICAM-1, VCAM-1), lipid peroxidation product 4-HNE, and nitric oxide bioavailability, accompanied by depletion of the anti-inflammatory cytokine IL-10, GSH content, GPX activity, and total antioxidant capacity within lung tissue. Thinner exposure also resulted in cell cycle arrest, appeared at the S and G2/M phases, decline in the anti-apoptotic BCL2 and increases in Bax, cytochrome-c, Bax/Bcl2 ratio, expression of P53 and caspase-3, and the proportions of annexin V/PI positive cells, indicating heightened apoptosis. Nevertheless, a higher reduction in lung inflammation, oxidative damage, and apoptosis were prominently observed following administration of chamomile tea to the thinner group.

Conclusion

Findings could verify the safety and efficacy of chamomile tea as a natural medication for thinner toxicity and related pulmonary damage.

Background

One potential strategy for cancer treatment is to prevent neovascularization. A well-targeted approach blocks VEGFR2, inhibiting the growth of new tumor vasculature. In this study, we report the identification of potential VEGFR2 inhibitors from phytochemicals previously extracted from Sonneratia alba, a mangrove species native to the Philippines, using molecular docking simulations followed by drug-likeness and ADME/Tox prediction.

Results

Thirty-two phytochemicals identified from various parts of S. alba were virtually docked onto the VEGFR2 binding site. Luteolin, ⍺-amyrin cinnamate, and ꞵ-amyrin cinnamate exhibited docking scores comparable to the drug control Axitinib. The drug-likeness property prediction revealed luteolin as the sole phytochemical predicted to have high bioavailability. In silico ADMET prediction demonstrated that luteolin has higher human intestinal absorption, is firmly bound to plasma protein, and poses no toxicity risks. Furthermore, luteolin also exhibited high permeability across the gastrointestinal tract but no passive permeability across the blood–brain barrier.

Conclusion

Through in silico techniques, luteolin was identified as the only compound from S. alba with adequate and significant potential of developing into a VEGF inhibitor drug, as exemplified by its good bioavailability, higher gastrointestinal absorption, strong binding affinity to plasma protein, and good permeability through the gastrointestinal tract. The findings of this investigation may help validate the in vitro and in vivo anticancer properties of luteolin, as described in several peer-reviewed articles.

Background

Plants have long been recognized as a rich source for medicinal agents, albeit many plant species have yet to be investigated. The genus Chlorophytum comprises over 215 species of perennial, rhizomatous herbs. The chemical composition and bioactivities of Chlorophytum krookianum remain uncharacterized in the existing scholar literature. This work investigates the phytochemistry and anticancer potential of C. krookianum.

Results

Phytochemical investigation of the unexplored C. krookianum aerial parts afforded the isolation and identification of eight compounds: β-sitosterol (1), stigmasterol (2), β-sitosterol-3-O-β-D-glucopyranoside (3), hydroxytyrosol (4), isovitexin (5), vicenin 2 (6), (25S)-gitonin (7), and vitexin-2″-O-rhamnoside (8). Dichloromethane and n-hexane fractions of C. krookianum aerial parts exhibited anticancer activity against breast (MDA-MB-231) and tongue (HNO-97) carcinoma cell lines. GC–MS analysis of the n-hexane fraction afforded the tentative identification of 41 metabolites with methyl palmitate, methyl 2,4-dimethyltetradecanoate, 6,10,14-trimethyl-2-pentadecanone, lanosterol, and 13-docosenamide as major compounds.

Conclusion

C. krookianum aerial parts, particularly the dichloromethane and n-hexane fractions, could be a potential source for anticancer activity as significant percentage inhibitions are obtained.

Among the various synthesis methods, fungi-based nanoparticles (NPs) have garnered significant attention due to their cost-effectiveness, eco-friendliness, and versatility compared to conventional physicochemical approaches.

Main body

Fungi possess unique metabolic pathways that facilitate the biosynthesis of NPs with distinct physicochemical properties, making them highly applicable to agriculture. These fungi-derived NPs exhibit strong and broad-spectrum antimicrobial activity against major phytopathogens, including Fusarium oxysporum, Rhizoctonia solani, and Sclerotinia sclerotiorum. This review comprehensively details the biological mechanisms and agricultural applications of these NPs. Furthermore, it explores the integration of machine learning (ML) to advance the field, demonstrating how ML models optimize synthesis parameters, predict NP stability, and enhance antimicrobial efficacy, thereby paving the way for scalable and standardized production. An advanced bibliometric analysis (2000–2024) underscores the rapid expansion of this research domain, with India emerging as a leading contributor, reflecting a global shift toward sustainable nanotechnology for plant disease management.

Conclusion

By synthesizing insights from fungal nanobiotechnology, AI-driven optimization, and global research trends, this review provides a forward-looking perspective on developing and implementing advanced, eco-friendly strategies for sustainable agriculture.
