Background: Acacia catechu is an important traditional medicinal plant that has been used to manage several ailments. Many in vitro and in vivo studies have demonstrated that it exhibits chemopreventive and antineoplastic effects by modulating diverse signaling pathways and molecular targets involved in cancer progression. This review attempts to systematically investigate the anticancer mechanisms of A. catechu, encompassing antiapoptotic, antioxidant, and antiproliferative activities. Material and Methods: This review was conducted using scientific databases such as Scopus, Web of Science, and Google Scholar, covering the studies from 2000 to 2024. The PRISMA methodology was applied, using the keywords A. catechu, phytoconstituents, and cancer. Results: A total of 39 studies were compiled from various databases that cited the biological use of A. catechu. The plant has an abundance of phenolic compounds, including catechin, epicatechin, epigallocatechin-3-O-gallate, and epicatechin-3-O-gallate, which show strong anticancer activities. The anticancer potential of A. catechu is explained as it regulates several modulators like reactive oxygen species and cytokines, and downregulates oncogenic molecules like c-myc and various signaling pathways, such as c-Jun and NF-κB. Conclusions: Our findings suggest that A. catechu and its bioactive constituents have the potential for cancer prevention and therapy. However, further mechanistic investigations using pure compounds, along with preclinical and clinical trials, are essential to translate this potential into clinical applications. Full article

Background/Objectives: Ecballium elaterium is a widely distributed species and is one of the earliest recorded in traditional medicine. With global temperatures rising, this study aimed to investigate the changes in E. elaterium plantlets subjected to thermal stress. The goal was to understand how thermal stress affects morphology, physiology, and bioactive metabolite production, both for ecological adaptation and potential therapeutic applications. Methods: Seedlings were cultivated under controlled conditions and subjected to either the control temperature (22 °C) or the heat stress temperature (35 °C) for one week. Morphological and anatomical traits were assessed, along with physiological parameters such as chlorophyll content, malondialdehyde (MDA), hydrogen peroxide (H₂O₂), L-proline, soluble sugars, and total phenolic content. Methanolic leaf extracts from both groups were analyzed via LC-HRMS/MS and examined in vitro for cytotoxic activity against three human cancer cell lines: MCF-7 (breast), DU-145 (prostate), and SH-SY5Y (neuroblastoma). Results: Heat stress reduced dry mass and stomatal density but increased the diameter of the root transition zone, indicating anatomical adaptation. Leaves exhibited elevated oxidative stress markers and altered metabolite accumulation, while the roots showed a more integrated stress response. LC-HRMS/MS profiling revealed significant shifts in Cucurbitacin composition. Extracts from heat-stressed plants displayed stronger cytotoxicity, particularly toward DU-145 and SH-SY5Y cells, correlating with higher levels of glycosylated Cucurbitacins. Conclusions: E. elaterium demonstrates organ-specific thermotolerance mechanisms, with heat stress enhancing the production of bioactive metabolites. These stress-induced phytochemicals, especially Cucurbitacins, hold promise for future cancer research and therapeutic applications. Full article

Background: Acute pancreatitis (AP) is characterized by the abnormal activation of pancreatic enzymes due to various causes, leading to local pancreatic inflammation. This can trigger systemic inflammatory response syndrome and multi-organ dysfunction. Hyperlipidemia, mainly resulting from lipid metabolism disorders and elevated triglyceride levels, is a major etiological factor in AP. This study aims to investigate the role of lipid metabolism-related genes in the pathogenesis of AP and to propose novel strategies for its prevention and treatment. Methods: We obtained AP-related datasets GSE3644, GSE65146, and GSE121038 from the GEO database. Differentially expressed genes (DEGs) were identified using DEG analysis and gene set enrichment analysis (GSEA). To identify core lipid metabolism genes in AP, we performed least absolute shrinkage and selection operator (LASSO) regression and support vector machine recursive feature elimination (SVM-RFE) analysis. Gene and protein interactions were predicted using GeneMANIA and AlphaFold. Finally, biomarker expression levels were quantified using Real-Time quantitative Polymerase Chain Reaction (RT-qPCR) in an AP mouse model. Results: Seven lipid metabolism-related genes were identified as key biomarkers in AP: Amacr, Cyp39a1, Echs1, Gpd2, Osbpl9, Acsl4, and Mcee. The biological roles of these genes mainly involve fatty acid metabolism, cholesterol metabolism, lipid transport across cellular membranes, and mitochondrial function. Conclusions: Amacr, Cyp39a1, Echs1, Gpd2, Osbpl9, Acsl4, and Mcee are characteristic biomarkers of lipid metabolism abnormalities in AP. These findings are crucial for a deeper understanding of lipid metabolism pathways in AP and for the early implementation of preventive clinical measures, such as the control of blood lipid levels.

Hongiastoma zhangbuensis sp. nov. is described from a tributary of the upper reach of the Pearl River basin based on the morphological and molecular data. It is distinguished from all known species within the subfamily Acrossocheilinae by having a combination of the following characteristics: a crescent horny sheath on the lower jaw, a less prominent lower lip limited to the corners of the mouth, a serrated posterior edge of the last simple dorsal-ray, 47–50 lateral-line scales, 9 scales above the lateral line, 16–18 circumpeduncular scales, and 16–18 pre-dorsal midline scales. The molecular phylogeny revealed that H. zhangbuensis sp. nov. was a sister taxon to Hongiastomata argentatum, with a genetic distance ranging from 10.49% to 10.68%. Together, they formed a lineage at the base of the Acrossocheilinae clade. Furthermore, the interspecific genetic distances between the new species and those of Onychostoma sensu lato ranged from 9.9 to 13.4%, indicating significant genetic divergence between this new species and all known species within Onychostoma sensu lato. Therefore, both morphological and molecular data support the recognition of this species as new. Full article

Background and Objectives: Live birth rates in women with diminished ovarian reserve (AMH < 2.0 ng/mL) undergoing in vitro fertilization (IVF) remain under 20%. While Chinese herbal medicine (CHM) is often used to treat infertility and support IVF, its effectiveness in this group is unclear. This study assessed live birth outcomes by treatment type and patient characteristics. Materials and Methods: We retrospectively analyzed 240 infertile women with low ovarian reserve and partners with normal sperm. Of these, 63 were in the control group, 118 received CHM only, and 59 received IVF with CHM. Logistic regression and a nomogram were used to assess live birth outcomes. Results: The live birth rate was 5% in the control group, 32% in the CHM-only group, and 42% in the mixed treatment group. Univariate analysis showed that both treatment type and patient age were significantly associated with live birth outcomes. In multivariate logistic regression, CHM-only treatment was significantly associated with an increased likelihood of live birth (odds ratio [OR]: 8.98, p = 0.001), as was the mixed treatment group (OR = 18.77, p < 0.001), with the control group as the reference. Women aged ≤37 had significantly higher live birth rates (OR = 3.24, p = 0.018), using those over 37 as the reference group. A predictive model was developed based on age, AMH level, and treatment type, achieving an area under the curve (AUC) of 0.756 for predicting live birth probability. Conclusions: This clinical prediction model offers guidance for couples and clinicians on pregnancy outcomes in low ovarian reserve patients treated with CHM alone or alongside IVF. Full article

Agarwood, valued for its resin, has long been used in perfumery, incense, and traditional medicine. Its resin is primarily derived from species of Aquilaria and is produced through a still-unknown process in response to biotic or abiotic stress. Concerns regarding agarwood’s sustainability and conservation have emerged because of the substantial loss of natural resources due to overharvesting and illegal trade. To address these concerns, artificial techniques are being used to produce agarwood. The mechanism underlying agarwood production must be elucidated to enhance yield. The authentication of agarwood species is challenging because of morphological similarities between pure and hybrid Aquilaria species. Techniques such as DNA barcoding, molecular marker assessment, and metabolomics can ensure accurate identification, facilitating conservation. Artificial intelligence and machine learning can support this process by enabling rapid, automated identification on the basis of genetic and phytochemical data. Advances in resin induction methods (e.g., fungal inoculation) and chemical induction treatments are improving yield and quality. Endophytic fungi and bacteria promote resin production at minimal harm to the tree. Agarwood’s pharmacological potential—antimicrobial, anti-inflammatory, and anticancer effects—has driven research into bioactive compounds such as sesquiterpenes and flavonoids for the development of novel drugs. This systematic review synthesized current evidence on species authentication, induction techniques, and pharmacological properties. The findings may guide future research aimed at ensuring sustainable use and enhancing the medicinal value of agarwood. Full article

Postmenopausal osteoporosis (PMOP) has become an important public health issue. The diagnosis of PMOP relies on clinical symptoms and radiology. However, most patients with PMOP do not exhibit obvious symptoms in the early stages of this disease. This study aimed to explore the feasibility of surface-enhanced Raman scattering (SERS) technology in the auxiliary screening of PMOP. PMOP rats were induced by ovariectomy (OVX) surgery, with a Sham group and an icariin (ICA) treatment group serving as controls. A monolayer film of Au nanoparticles (NPs) was prepared using the Marangoni effect in an oil/water/oil three-phase system, and was used to detect serum SERS signals in the Sham, OVX, and ICA treatment groups. Then, the spectral diagnostic model for PMOP screening was established utilizing partial least squares (PLS) and support vector machine (SVM) algorithms. Histopathology confirmed the establishment of the PMOP rat model. The assignment of Raman peaks and the analysis of spectral differences revealed the biochemical changes associated with PMOP, including the upregulation of tyrosine levels and the downregulation of arginine, tryptophan, lipids, and collagen. When employing the PLS-SVM algorithm to simultaneously classify and discriminate three groups of samples, the diagnostic sensitivity for PMOP is 93.33%, the specificity is 96.67%, and the accuracy of three-class classification is 91.11%. This study demonstrated the potential of SERS for the auxiliary screening of PMOP. Full article

This narrative review consolidates existing evidence about the interaction between Epstein-Barr virus (EBV) and SARS-CoV-2 in cancer development. EBV is a recognized oncogenic driver, whereas COVID-19 may heighten cancer risk by immunological dysregulation, persistent inflammation, and reactivation of latent viruses. We underscore molecular similarities (e.g., NF-κB activation, T-cell exhaustion) and clinical ramifications for high-risk individuals, stressing the necessity for interdisciplinary research to alleviate dual viral risks. EBV, a well-known oncogenic virus, has been linked to numerous malignancies, including lymphomas, nasopharyngeal carcinoma, and gastric cancer. Through the production of viral proteins that interfere with immune evasion, cellular signaling, and genomic integrity, it encourages malignant transformation and ultimately results in unchecked cell proliferation. Because of its capacity to induce tissue damage, immunological dysregulation, and chronic inflammation, COVID-19, which is brought on by the SARS-CoV-2 virus, has become a possible carcinogen. The virus’s influence on cellular pathways and its long-term effects on the immune system may raise the chance of malignancy, particularly in people with pre-existing vulnerabilities, even if direct correlations to cancer are still being investigated. When two viruses co-infect a host, the review highlights the possibility of synergistic effects that could hasten the development of cancer. It describes how overlapping mechanisms like inflammation, immune suppression, and viral reactivation may be used by a combined EBV and COVID-19 infection to exacerbate carcinogenic processes. Gaining an understanding of these relationships is essential for creating tailored treatment plans and enhancing cancer prevention in high-risk groups. Full article

For centuries, Scaptotrigona mexicana honey has been treasured in Mexico, where pre-Columbian cultures harvested it not only for its sweet flavor but also for its medicinal and ceremonial purposes. Today, it remains a high-value product in local markets, prized above Apis mellifera honey for its unique sensory qualities and traditional health benefits. Yet its scientific characterization and functional potential remain underexplored. In this study, twenty-four samples from diverse regions were analyzed to quantify bioactive compounds and determine physicochemical composition, α-amylase inhibition, and antioxidant activity. Non-parametric statistical tests revealed distinct compositional clusters, with samples from Cruz Blanca showing exceptional phenolic content and stronger α-amylase inhibition (5.6–49.2%). Antioxidant capacity correlated positively with phenols and flavonoids, showing moderate effect sizes for ABTS (η² = 0.49) and DPPH (η² = 0.37). Compared with Apis mellifera honey, Scaptotrigona mexicana contained more moisture, free acidity, phenols, and antioxidants, but less diastase, hydroxymethylfurfural, and reducing sugars. Importantly, natural α-amylase inhibitors can help modulate postprandial glucose, offering dietary support for type 2 diabetes management. Kinetic analyses (EC50, Vmax, and Km) suggested mixed inhibition. These findings highlight Scaptotrigona mexicana as both a heritage product and a promising functional ingredient for developing foods that merge tradition with metabolic health innovation.

This study aims to further analyze the chemical characteristics of mountainous forest cultivated ginseng (MFCG) and garden ginseng (GG), concerning their calcium oxalate crystals, organic acids, and ginsenosides. The results demonstrate that MFCG had higher levels of non-free oxalate, calcium oxalate crystals, and most ginsenosides, while GG had higher fumaric acid/total organic acids. The content of non-free oxalate and calcium oxalate crystals in rhizome was the highest, showing a positive correlation with the growth years (5–20 years). In most cases, in MFCG, non-free oxalic acid ≥ 0.8%, calcium oxalate ≥ 160/mg, fumaric acid/total organic acids < 9%, Rb1 ≥ 6 mg/g, PPD/PPT was close to 2, and Rb1/Ro ≥ 2.5, while in GG, non-free oxalic acid < 0.8%, calcium oxalate ≤ 60/mg, fumaric acid/total organic acids ≥ 9%, Rb1 < 6 mg/g, PPD/PPT was close to 1, and Rb1/Ro < 2.5. These results can be used as the basis for distinguishing between GG and MFCG. Chemometric analysis of non-free oxalate, calcium oxalate crystals, and ginsenosides could distinguish MFCG from GG. Chemometric analysis of succinate, citrate, and malonic acids could mostly differentiate MFCG of over 15 years from that of less than 12 years. As far as we know, the present study is the first to determine the difference in the ratio of ginsenosides (Rb1/Ro, PPD/PPT) and the ratio of organic acids, which provides an innovative method for the distinction between the two and a scientific basis for effective quality control of MFCG.

The incidence and prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) are increasing, and, currently, the disease affects approximately 30% of the global population. Therefore, there is a growing need for widely available, patient-friendly, and reliable diagnostic tools. Our review is focused on the presentation and discussion of emerging biomarkers for evaluation and non-invasive detection of liver fibrosis in patients with MASLD, including glycation markers (AGEs/sRAGE), lipid mediators (eicosanoids), fetuin-A, collagen turnover markers (PRO-C3, ADAPT), and omic-based technologies. As reported recently, some of these parameters revealed high diagnostic accuracy in clinical trials, so they may be incorporated as key diagnostic tools in the future MASLD approach. Employment of such biomarkers may enable correct and quick identification of MASLD and/or MASH patients, as well as better monitoring of their treatment response. The development of precision medicine, driven by multiomics and individualized profiling, promises a rearrangement from the traditional “one size fits all” to tailoring targeted care, as environmental factors may have an even more relevant impact on MASLD pathogenesis in comparison with genetic predisposition. Nevertheless, to enable their widespread clinical use, novel biomarkers require further rigorous validation and standardized implementation in healthcare settings. Full article

Automated electroencephalography (EEG) seizure detection is meaningful in clinical medicine. However, current approaches often lack comprehensive feature extraction and are limited by generic classifier architectures, which limit their effectiveness in complex real-world scenarios. To overcome this traditional coupling between feature representation and classifier development, this study proposes DySC-MDE, an end-to-end co-designed framework for seizure detection. A novel multi-domain entropy (MDE) representation is constructed at the feature level based on amplitude-sensitive permutation entropy (ASPE), which adopts entropy-based quantifiers to characterize the nonlinear dynamics of EEG signals across diverse domains. Specifically, ASPE is extended into three distinct variants, refined composite multiscale ASPE (RCMASPE), discrete wavelet transform-based hierarchical ASPE (HASPE-DWT), and time-shift multiscale ASPE (TSMASPE), to represent various temporal and spectral dynamics of EEG signals. At the classifier level, a dynamic synapse classifier (DySC) is proposed to align with the structure of the MDE features. Particularly, DySC includes three parallel and specialized processing pathways, each tailored to a specific entropy variant. These outputs are then adaptively fused through a dynamic synaptic gating mechanism, which can enhance the model’s ability to integrate heterogeneous information sources. To fully evaluate the effectiveness of the proposed method, extensive experiments are conducted on two public datasets using cross-validation. For the binary classification task, DySC-MDE achieves an accuracy of 97.50% and 98.93% and an F1-score of 97.58% and 98.87% in the Bonn and CHB-MIT datasets, respectively. Moreover, in the three-class task, the proposed method maintains a high F1-score of 96.83%, revealing its strong discriminative performance and generalization ability across different categories. Consequently, these impressive results demonstrate that the joint optimization of nonlinear dynamic feature representations and structure-aware classifiers can further improve the analysis of complex epileptic EEG signals, which opens a novel direction for robust seizure detection.

Background: Influenza A virus (IAV) is a major human pathogen, contributing to substantial morbidity and mortality during seasonal outbreaks and pandemics. Human infection with IAV can lead to pneumonia and acute respiratory distress syndrome (ARDS), and numerous clinical and basic research studies have established an association between IAV and pulmonary fibrosis (PF). However, the treatment of IAV-induced PF fibrosis has not been studied and discussed. Methods: An IAV-induced PF mouse model was established. Herbacetin (HBT) was identified as the most effective compound in the in vitro study of seven components of Rhodiola rosea L. (R. rosea L.). The effect of HBT on IAV-induced lung injury and PF was evaluated in vivo and in vitro. The binding between HBT and neuraminidase (NA) protein was investigated by biological layer interferometry (BLI) and cell thermal shift assay (CETSA). Results: Following IAV infection, the TGF-β/Smad3 pathway is activated, leading to the upregulation of fibrosis-related proteins that promote fibrosis. HBT exhibited a significant ability to reduce influenza virus-induced lung injury and fibrosis both in vitro and in vivo. Mechanistically, HBT binds to the NA protein of the influenza virus, reducing viral infection and the activation of the TGF-β/Smad3 pathway, thereby mitigating the formation of lung injury and PF. Conclusions: HBT represents a promising therapeutic agent for modulating influenza virus-induced lung injury and PF, marking a significant step toward the development of effective treatments for influenza-induced PF.

Background and Objectives: Musculoskeletal pain is a global public health issue. Eight Constitution Medicine (ECM), a type of East Asian Traditional Medicine, offers personalized, minimally invasive treatment through Eight Constitution Acupuncture (ECA) and Eight Constitution Lifestyle Intervention (ECLI). Despite its clinical use, scientific evidence supporting ECM’s effectiveness remains limited. This study aimed to evaluate the effectiveness in treating musculoskeletal pain in primary care settings. Materials and Methods: This retrospective study analyzed medical records from three ECM clinics (Gangnam-Shingwang, Yeson, and Yebon) between January 2018 and August 2023. A total of 163 patients were included, with 44 providing follow-up data. Pain intensity, quality of life, and functional outcomes were assessed using validated instruments including the PainDETECT questionnaire, Korean Cancer Pain Assessment Tool (KCPAT) somatic pain scores, EuroQol 5-Dimension 5-Level (EQ-5D-5L), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oswestry Disability Index (ODI), Neck Disability Index (NDI), and Shoulder Pain and Disability Index (SPADI). Pre- and post-treatment scores were statistically analyzed. Results: Significant decreases were observed in KCPAT somatic pain scores (11.77 ± 4.77 to 9.77 ± 5.32) and significant improvements in EQ-5D-5L scores (0.74 ± 0.12 to 0.80 ± 0.07). WOMAC and ODI scores also showed significant improvements. However, the changes in the NDI, SPADI, and PainDETECT scores were not statistically significant. No adverse events were reported. Conclusions: ECM, through ECA and ECLI, may offer effective personalized treatment for musculoskeletal pain, improving both pain intensity and quality of life. Despite its small sample size and retrospective design, this study offers valuable preliminary evidence for ECM. Further large-scale prospective studies are needed to confirm these findings.
