Lignans are naturally occurring compounds found in a wide variety of plant species, including flaxseed, soybean, pumpkin seed, broccoli, sesame seed, and some berries. Lignans have been used for centuries in both food and traditional herbal medicine. Recently, numerous new lignans and lignan derivatives with diverse biological properties have been identified. Lignans are considered promising for human health due to their hydrogen-donating antioxidant activity together with their ability to complex divalent transition metal cations. They have demonstrated beneficial effects for cardiovascular disease, as well as in maintaining blood glucose levels, supporting cardiac health, promoting anti-obesity effects, decreasing the risk of renal diseases, enhancing brain function, improving skin and gut health, among others. This review explores the biosynthesis and biological effects of lignans, with a particular focus on their antihypertensive and anti-obesity properties, as well as the molecular mechanisms involved. It also highlights recent advances in sustainable lignan extraction techniques that are suitable for human use. The mechanisms underlying these bioactivities are thought to involve hormonal metabolism and availability, antioxidant action, modulation of angiogenesis, and more. However, further research is needed to fully elucidate the molecular pathways through which lignans exert their therapeutic effects. Overall, lignans from various plant sources hold significant potential for application in functional foods, dietary supplements, and pharmaceutical products aimed at preventing and managing a range of health conditions, including hypertension and obesity.

Background: Vitamin E has been studied for its role in reducing the growth of colorectal cancer (CRC). CRC is a worldwide health concern. A meta-analysis reported that CRC patients have a lower concentration of serum vitamin E, suggesting it to be a risk factor. Although rodent models are widely used in disease research, their application in studying vitamin E as a preventive or therapeutic agent in CRC is not well characterized. To address this gap, we conducted a scoping review to examine the available evidence, adhering to the PRISMA-ScR checklist. Methods: We searched PubMed, Google Scholar, Scopus, and Web of Science (WoS) for full-text English original articles published before May 2024, using Medical Subject Headings (MeSH) terms and free text. The following search string strategy was applied: (Vitamin E OR tocopherol$ OR tocotrienol$) AND (Colo$ cancer OR colo$ carcinoma) AND (Rodentia OR mouse OR Rodent$ OR mice OR murine OR rats OR guinea OR rabbit OR hamsters OR Animal model OR Animal testing OR animals) AND (neoplasm$ OR “tumor mass” OR tumor volume OR tumor weight OR tumor burden). Data were charted into five categories using a standardized, pretested form. The charted data were synthesized using descriptive and narrative methods. Conclusions: This study highlights that γ- and δ-tocopherols, as well as δ-tocotrienol and its metabolites, were reported to reduce tumor volume and formation in various rodent models. While these results are promising, this scoping review identifies a need for further research to address translational barriers such as dosing, bioavailability, and long-term safety before clinical application.

Contrast-induced acute kidney injury (CIAKI) has emerged as the third most prevalent etiology of clinically acquired acute kidney injury, with a lack of specific preventive and therapeutic strategies. Rubia Cordifolia L. (madder root), a medicinal herb with a long-standing history and extensive clinical application, exhibits multiple pharmacological activities. This study aimed to clarify the renal protective effect of Rubia cordifolia L. dichloromethane extract (RCDE) on CIAKI modeling rats and investigate potential anti-apoptotic and autophagy-inducing effects molecular mechanisms. In this study, RCDE constituents were identified by UPLC-Q-TOF-MS. A CIAKI rat model was established to evaluate the nephroprotective effect of RCDE. The results showed that RCDE high-dose group significantly decreased serum SCr and BUN levels, attenuated renal histopathological damage, and modulated oxidative stress markers by decreasing MDA and CAT while increasing SOD, compared with the model group. It downregulated the expressions of Bcl-2, caspase-3 and p62, upregulated the expressions of Bax, Beclin1 and reduced the LC3B-II/LC3B-I ratio in renal tissues. Molecular docking indicates that anthraquinone compounds are probably the principal active constituents of RCDE. This study provides experimental evidence for the intervention efficacy of RCDE against CIAKI. Full article

The blood–brain barrier (BBB) restricts therapeutic delivery to the central nervous system (CNS), hindering the treatment of neurological disorders, such as Alzheimer’s disease, Parkinson’s disease, brain cancers, and stroke. Aptamers, short single-stranded DNA or RNA oligonucleotides that can fold into unique 3D shapes and bind to specific target molecules, offer high affinity and specificity, low immunogenicity, and promising BBB penetration via receptor-mediated transcytosis targeting receptors such as the transferrin receptor (TfR) and low-density lipoprotein receptor-related protein 1 (LRP1). This review examines aptamer design through the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) and its variants, mechanisms of BBB crossing, and applications in CNS disorders. Recent advances, including in silico optimization, in vivo SELEX, BBB chip-based MPS-SELEX, and nanoparticle–aptamer hybrids, have identified brain-penetrating aptamers and enhanced the brain delivery efficiency. This review highlights the potential of aptamers to transform CNS-targeted therapies. Full article

Immune checkpoint inhibitors (ICIs) for cancer therapy may induce immune-related adverse events including myocarditis, which occurs infrequently but carries a high mortality rate. Crocins are the active constituents derived from Crocus sativus L. (saffron), and have demonstrated various bioactivities including anti-tumor, anti-inflammation, antioxidation, anti-ischemia, anti-aging, and neuroprotective effects. This study established a subcutaneous xenotransplanted tumor model of human liver cancer in nude mice to better mimic ICI-related myocarditis. Animal experimental results revealed that crocins improved cardiac function, relieved myocardial damage and autoimmune response, and suppressed oxidative stress and inflammatory reaction. Quantitative proteomics and Western blotting verification confirmed that crocins ameliorated experimental ICI-related myocarditis by targeting the Hpx/Nrf2/HO-1 pathway. Molecular docking revealed that the best docking activities were demonstrated by crocin I–HO-1, crocin II–Hpx, and crocin III–Nrf2. These findings shed new light on the development of therapeutic strategies for treating ICI-related myocarditis and provided the fundamental basis for expanding the clinical application of crocins.

Background/Objective: Current treatments for peripheral nerve injury (PNI) lack robust evidence to suggest complete recovery; hence, alternative therapeutics offer new opportunities to develop more effective protocols. Mushroom species and their related components are considered potential candidates for peripheral nerve repair, but their specific effects and underlying mechanisms are not fully understood. This systematic review presents the available evidence on the use of mushroom species for PNI therapy, including the bioactive components and mechanisms of action. Methodology: A comprehensive literature search in three databases (PubMed, Scopus, and Google Scholar) led to the synthesis of 11 records published between 2010 and 2024. Qualitative analysis revealed the neuroregenerative potential of four mushrooms: Amanita muscaria (n = 2), Hericium erinaceus (n = 5), Lignosus rhinocerotis (n = 3), and Flammulina velutipes (n = 1), with aqueous extracts as the most common type of ingredients used (n = 4) relative to specific components such as muscimol, polysaccharide, Erinacine S, and nerve-guided conduits (NGCs). Results: These mushroom-derived treatments enhanced the migration of Schwann cells mainly via the FGF-2 signalling and MAPK pathway. In vivo studies also revealed the ability of H. erinaceus, A. muscaria, and L. rhinocerotis to promote peripheral nerve repair and functional recovery, with evidence suggesting the role of neurotrophic factors, anti-apoptotic signalling, and pro-inflammatory substances. H. erinaceus was identified as the most promising for potential clinical applications, given the stronger evidence-based data and its relatively safer components compared to A. muscuria and other mushroom species. Conclusions: Despite presenting the potential use of mushrooms in managing PNIs, the existing approaches need to be subjected to clinical research to accelerate the development of future therapeutics and preventive measures for PNIs.

Background: Chronic nonspecific neck pain (CNNP) is a widespread musculoskeletal condition affecting individuals across all age groups. Although cervical stabilization exercises (CSE) and Thai self-massage have each demonstrated therapeutic potential, evidence regarding the effectiveness of the combined applications of CSE and Thai self-massage remains limited. This study aimed to investigate the effects of a combined program of CSE and Thai self-massage (CSTM) on pain intensity (PI), pressure pain threshold (PPT), and neck disability (ND) in young adults with CNNP. Methods: This single-blind randomized controlled trial was conducted at the Department of Physical Therapy, School of Integrative Medicine, Mae Fah Luang University, Thailand. Fifty young adults with CNNP were randomly assigned into two groups. The CSTM group performed CSE integrated with Thai self-massage, whereas the control group practiced stretching exercises exclusively. Both groups engaged in their respective programs three times per week for a duration of four weeks. PI, PPT, and ND were assessed at baseline, after four weeks (Week 4), and at a two-week follow-up (Week 6). Results: Both groups showed significant improvements in PI, PPT, and ND (p < 0.05), representing within-group comparisons, at Week 4 and Week 6. Furthermore, between-group comparisons at Week 4 and Week 6 indicated that the CSTM group achieved significantly greater improvements in PI and ND than the control group (p < 0.05). Conclusion: A four-week program combining CSE with Thai self-massage was effective in reducing pain intensity and neck disability in young adults with CNNP, with benefits maintained at short-term follow-up. Trial registration: Thai Clinical Trials Registry (TCTR20231102008), registered on 2 November 2023. Full article

Cryotherapy and radiofrequency (RF) treatments modulate tissue temperature to induce therapeutic effects; however, improper application can result in thermal injury. Traditional temperature-based monitoring methods rely on multiple thermal sensors whose accuracy strongly depends on their number and spatial positioning, often failing to detect early tissue crystallization. This study introduces a fractional order bioimpedance modelling framework for the early detection of tissue freezing during cryogenic and thermal medical treatments, with the feasibility and effectiveness of this approach having been reported in our prior publications. While bioimpedance spectroscopy itself is a well-est. The corresponablished technique in biomedical engineering, its novel application to predict and identify premature freezing events provides a new pathway for safe and efficient energy-based therapies. Fractional-order models derived from the Cole family accurately reproduce the complex electrical behavior of biological tissues using fewer parameters than classical integer-order models, thus reducing both hardware requirements and computational cost. Experimental impedance data from human abdominal, gluteal, and femoral regions were modelled to extract fractional parameters that serve as sensitive indicators of phase-transition onset. The results demonstrate that the proposed approach enables real-time identification of freezing-induced electrical transitions, offering a physiologically grounded alternative to conventional temperature-based monitoring. Furthermore, the fractional order bioimpedance method exhibits high reproducibility and selectivity, and its analytical figures of merit, including the limits of detection and quantification, support its use for reliable real-time tissue monitoring and early injury detection. Overall, the proposed fractional order bioimpedance framework enhances both safety and control precision in cryogenic and thermal medical applications. Full article

Type 2 diabetes mellitus (T2DM) is a multifaceted metabolic disorder marked by impaired insulin action, pancreatic β-cell dysfunction, and the involvement of several interconnected mechanisms, including inflammation, oxidative stress, and epigenetic alterations. Despite progress in conventional therapies, achieving durable glycemic control and minimizing complications remain major challenges. This review discusses the emerging role of bioactive phytochemicals—such as curcumin, berberine, resveratrol, flavonoids, and polysaccharides—in modulating essential molecular pathways including AMPK, PI3K/AKT, and cAMP/PKA, which contribute to enhanced insulin sensitivity, glucose regulation, and β-cell protection. These natural compounds also influence gut microbiota modulation and epigenetic mechanisms, offering additional metabolic and anti-inflammatory benefits. This review synthesizes evidence from peer-reviewed studies published between 2000 and 2024, incorporating bibliometric trends showing an increasing research focus on phytochemicals for T2DM management. However, limitations such as low solubility, instability, and poor absorption restrict their clinical application. Advances in nanotechnology-based delivery systems, including nanoparticles, liposomes, and nanoemulsions, have shown potential to overcome these barriers by improving stability, bioavailability, and targeted delivery of phytochemicals. The integration of gut microbiota modulation with nanocarrier-enabled phytochemical therapy supports a precision medicine approach for managing T2DM. Preliminary clinical evidence highlights significant improvements in glycemic control and inflammatory status, yet further large-scale, well-controlled trials are essential to ensure safety, optimize dosages, and standardize combination regimens. Overall, phytochemical therapies, reinforced by nanotechnology and microbiota modulation, present a promising, safe, and holistic strategy for T2DM management. Continued interdisciplinary research and clinical validation are crucial for translating these advances into effective therapeutic applications and reducing the global diabetes burden. Full article

Liver cancer remains a significant global health challenge, with hepatocellular carcinoma (HCC) being the most prevalent form. Despite advancements in treatment, high recurrence rates and the limited efficacy of conventional therapies highlight the need for novel interventions. Cinobufagin (CB), a bufadienolide extracted from the parotid secretion of Bufo gargarizans and B. melanostictus, has emerged as a promising compound with multiple antitumor mechanisms. This comprehensive review assesses the current evidence regarding CB and its containing medicine, cinobufacini, in liver cancer models. Cinobufacini is a traditional Chinese medicine extract, whereas CB refers specifically to one of its active components. The pharmacodynamic actions of CB include induction of apoptosis, DNA damage, inhibition of proliferation and migration, and modulation of key oncogenic pathways such as PI3K/Akt/mTOR, Akt/ERK, and AURKA-mTOR-eIF4E. Additionally, CB disrupts tumor metabolism and induces oxidative stress. Preclinical studies, both in vitro and in vivo, demonstrate significant antitumor efficacy. However, concerns remain regarding CB’s toxicity profile at high doses. This review emphasizes the therapeutic potential of CB in HCC treatment and advocates for further translational research to optimize its clinical applicability, dosage, and safety. Full article

Prostate cancer remains the most frequently diagnosed malignancy in men and a leading cause of cancer-related mortality. Multiparametric MRI (mpMRI) has become the gold standard for non-invasive diagnosis, staging, and follow-up. Yet, its widespread adoption is hampered by long acquisition times, inter-reader variability, and interpretative complexity. Though most papers focus on specific applications without offering a cohesive therapeutic perspective, artificial intelligence (AI) has recently attracted attention as a potential solution to these shortcomings. For instance, deep learning models can help optimize imaging protocols for biparametric and multiparametric MRI, and AI-based reconstruction techniques have shown promise for reducing acquisition times without sacrificing diagnostic performance. Several systems have produced outcomes in the diagnostic phase that are comparable to those of skilled radiologists, as demonstrated in multicenter settings such as PI-CAI. Radiomics and radiogenomics provide more detailed insights into the biology of the disease by extracting quantitative features associated with tumor aggressiveness, extracapsular expansion, and treatment response, in addition to detection. Despite these developments, methodological variability, a lack of multicenter validation, proprietary algorithms, and unresolved standardization and governance difficulties continue to restrict clinical translation. Our work emphasizes the maturity of existing technologies, ongoing gaps, and the progressive integration necessary for successful clinical adoption by presenting AI applications aligned with the patient pathway. In this context, this review aims to outline how AI can support the entire patient journey—from acquisition and protocol selection to detection, quantitative analysis, treatment assessment, and follow-up—while maintaining a clinically centered perspective that emphasizes practical relevance over theoretical discussion, potentially enabling more reliable, effective, and customized patient care in the field of prostate cancer.

CRISPR/Cas systems have transformed molecular medicine, yet the field still lacks principled guidance on when transient editing suffices versus when sustained exposure through in vivo viral delivery is necessary and how to keep prolonged exposure safe. Notably, EDIT-101 was designed for a permanent edit in post-mitotic photoreceptors with lifelong Cas9 persistence. This review addresses this gap by defining the biological and therapeutic conditions that drive benefit from extended Cas activity while minimizing risk. We will (i) examine relationships between expression window and efficacy across Cas9/Cas12/Cas13 modalities, (ii) identify genome-wide off-target liabilities alongside orthogonal assays, and (iii) discuss controllable, self-limiting, and recallable editor platforms. By separating durable edits from persistent nuclease exposure, and by providing validated control levers, this work establishes a generalizable framework for safe, higher-efficacy CRISPR medicines. Furthermore, we highlight key studies in cell lines, murine models, non-human primates, and humans that examine the long-term effects of sustained expression of CRISPR/Cas systems and discuss the safety and efficacy of such approaches. Current evidence demonstrates promising therapeutic outcomes with manageable safety profiles, although there is a need for continued monitoring as CRISPR/Cas therapies are increasingly applied in clinical contexts and therapies are developed for broader clinical applications.

Ionic liquids (ILs) have emerged as multifunctional compounds with low volatility, high thermal stability, and tunable solvation capabilities, making them highly promising for biomedical applications. First explored in the late 1990s and early 2000s for enhancing the thermal stability of enzymes, antimicrobial agents, and controlled release systems, ILs have since gained significant attention in drug delivery, antimicrobial treatments, medical imaging, and biosensing. This review examines the diverse functions of ILs in contemporary therapeutics and diagnostics, highlighting their transformative capabilities in improving drug solubility, bioavailability, transdermal permeability, and pathogen inactivation. In drug delivery, ILs improve solubility of bioactive compounds, with several IL formulations achieving substantial solubility enhancements for poorly soluble drugs. Bio-ILs, in particular, show promise in enhancing drug delivery systems, such as improving transdermal permeability. ILs also exhibit significant antimicrobial and antiviral activity, offering new avenues for combating resistant pathogens. Despite their broad potential, challenges such as cytotoxicity, long-term metabolic effects, and the stability of ILs in physiological conditions persist. While much research has focused on their physicochemical properties, biological activity and in vivo studies are still underexplored. The future directions for ILs in biomedical applications include the development of bioengineered ILs and hybrid ILs, combining functional components like nanoparticles and polymers to create multifunctional materials. These ILs, derived from renewable resources, show great promise in personalized medicine and clinical applications. Further research is necessary to evaluate their pharmacokinetics, biodistribution, and long-term safety to fully realize their biomedical potential. This study emphasizes the potential of ILs to transform therapeutic and diagnostic technologies by highlighting present shortcomings and offering pathways for clinical translation, while also debating the need for continuous research to fully utilize their biomedical capabilities.

Background/Objectives: The expansion of intensive swine production in Córdoba, Argentina, underscores the need to assess the risks associated with antimicrobial (AM) use, whose extensive application has driven antimicrobial resistance, a major global threat within the One Health framework. This study aimed to characterize AM use practices and evaluate the epidemiological resistance profiles (non-wild-type phenotypes, NWT) of commensal Escherichia coli of fecal origin from swine farms, using epidemiological cut-off values (ECOFFs) as a surveillance criterion. Methods: An observational cross-sectional study was conducted in 19 farrow-to-finish farms in Córdoba during 2023. Information on AM use (prophylaxis, metaphylaxis, treatment) across production categories was collected. A total of 437 E. coli isolates were obtained from fecal samples, and minimum inhibitory concentrations (MICs) were determined for 10 AMs of critical importance for human and animal health. NWT phenotypes were classified according to EUCAST ECOFFs, and multidrug resistance (MDR) was assessed. Results: AM use was frequent and predominantly prophylactic (89.5% of farms), mainly through mass medication (66.3%), with macrolides and amoxicillin being the most commonly administered AMs. NWT proportions were extremely high (90–92%) for ampicillin, tetracyclines, and chloramphenicol and substantial for ciprofloxacin (50.6%), sulfamethoxazole (68.2%), and trimethoprim (44.9%). Extended-spectrum β-lactamase (ESBL)-producing phenotypes were detected. Alarmingly, 92% of isolates were classified as MDR E. coli, with homogeneous distribution across production categories. Conclusions: Findings reveal intensive and largely empirical AM use that has consolidated a stable intestinal resistome in the swine population. High MDR levels, even in categories with limited direct AM exposure or involving banned compounds, suggest that co-selection and horizontal gene transfer are key drivers of resistance. This scenario highlights the urgent need to strengthen integrated surveillance and promote prudent AM use strategies under the One Health approach to preserve therapeutic efficacy. Full article

Curcumin is a polyphenolic compound isolated from Curcuma longa, which is widely recognized for its therapeutic properties: particularly its strong anti-inflammatory and antioxidant activities. However, its practical incorporation into functional foods, especially aqueous dairy beverages, is severely hindered by its extremely low water solubility, poor chemical stability (notably at the near-neutral pH of milk), and very limited oral bioavailability. This review provides a critical synthesis of the literature published in the last two decades, with a focus on the development and application of food-grade oil-in-water (O/W) nanoemulsions to advanced colloidal delivery systems. It covers the fundamental principles of nanoemulsion formulation, including the selection of the oil phase, surfactants, and stabilizers, as well as both high-energy and low-energy fabrication techniques. It further examines the integration of these nano-delivery systems into dairy matrices (milk, yogurt, cheese), highlighting key interactions between nanoemulsion droplets and native dairy constituents such as casein micelles and whey proteins. Critically, findings indicate that nanoencapsulation not only enhances curcumin’s solubility but also protects it from chemical degradation during industrial processes, including pasteurization and sterilization. Moreover, the dairy matrix structure plays a key role in modulating curcumin bioaccessibility, with fortified products frequently exhibiting enhanced stability, shelf life, and sensory attributes. Finally, key technological challenges addressed the heterogeneous global regulatory landscape surrounding biopolymers and future trends: most notably, the growing shift toward “clean-label” biopolymer-based delivery systems.
