Oral literature transcends from orality to scribality and then textuality due to technological innovation. This paper seeks to evaluate the value of the characteristics of orality as applied by Oliver Kgadime Matsepe in his novel Legitaphiri (Unsolved Problem) (2008). This will be done by taking into account the significance of self and community in a developing and changing society. It is important to note that all cultures are born from orality. However, the changes that the self and community undergo have a strong impact on the communications models within the community. This is influenced by the self and community, as the writer expresses his/her views by means of language that is based on a particular community. 展开更多

Chitosan(CS),a natural polymer derived from chitin found in the exoskeletons of crustaceans,has garnered significant interest in the pharmaceutical field due to its unique properties,including biocompatibility and biodegradability.In recent years,various studies have reported that CS can affect drug bioavailability,and interestingly,it works as an oral absorption enhancer and inhibitor.This review offers an in-depth analysis of the mechanisms underlying such a phenomenon and supports its application as a pharmaceutical excipient.CS enhances oral drug absorption through various mechanisms,such as interaction with the intestinal mucosa,tight junction modulation,inhibition of efflux transporters,enzyme inhibition,solubility and stability enhancement,and complexation.On the other side,CS exhibits the ability to inhibit the absorption of certain drugs by adsorbing to lipids and sterols,modulating bile acids and gut microbiota,altering drug-cell interaction at the polar interface,and mucus-mediated entrapment and interference.Future potential pharmaceutical research in this field includes elucidating the underneath absorption relevant mechanisms,rational use in formulations as excipient,exploring functional CS derivatives,and developing CS-based drug delivery systems.This comprehensive review highlights CS's versatile and significant role in enhancing and inhibiting oral drug absorption,providing insights into the complexities of drug delivery and the potential of CS to improve therapeutic outcomes. 展开更多

The objective of this study was to understand the effect of long-term aconitine(AC)oral administration on the digestive tract and serum metabolism.Subjects consumed either 0.9%Na Cl(n=8)or AC(n=17)gavage designed to represent human chronic AC administrations for 13 days.Organ pathology was determined using hematoxylin-eosin staining and immunohistochemistry.Fecal and proximal intestinal content samples were collected to perform shotgun metagenomic sequencing.Serum samples were collected,and untargeted metabolomics was performed.In this study,AC administration induced proximal intestine,liver,and kidney injury.Microbiome composition remained stable after AC exposure,while several microbes presented dynamic alteration.Moreover,AC affected the abundance of the fatty acid biosynthesis rate-limiting gene acc A at day 7.AC induces 30 serum metabolites to significantly change at day 14,including several short-chain acylcarnitines.WGCNA revealed 2 sub-modules associated with the level of several short-chain acylcarnitines.In summary,AC affects the digestive tract and serum metabolism after chronic administration.AC may affect the enrichment of microbial-derived acc A gene.The abundance of serum acylcarnitines detected in the AC group may associate with its anti-heart failure effects. 展开更多

The thoracic duct(TD),the largest lymphatic vessel in the human body,plays a critical role in returning lymph to the circulatory system.However,its dynamic,distensible nature and concealed anatomical location make intraoperative visualization critically challenging and increase the risk of injury.Real-time,high-resolution assessment of TD leaks remains an urgent clinical need.Here,we present a breakthrough molecular engineering strategy that leverages an intestinally lipophilic fluorescent formulation for dynamic in vivo TD imaging.Our rationally designed cyanine derivative IR790+,known for its rapid membrane permeability and endoplasmic reticulum(ER)targeting localization,demonstrates unprecedented chylomicron affinity,which subsequently transports the dye through the lymphatic system to the TD.Notably,dynamic,high-contrast intraoperative TD imaging is achieved from rat models to swine models.Administered orally as near-infrared(NIR)fluorescent contrast agent,this ultra-stable IR790+@oil formulation,engineered via flash nanoprecipitation,surpasses conventional counterparts by enabling non-invasive,real-time identification of TD.Intriguingly,this first-reported ER-targeting NIR formulation,delivered orally,represents a paradigm shift in fluorescence-guided surgery,significantly improving intraoperative accuracy. 展开更多

After the“Ballad Movement”in the early 20th century revealed and systematized the Liang Zhu legend,numerous literary works had created a rich body of classic reinterpretations.This paper argues that Yang Yinshen’s A Storm stands as the earliest modern literary creation that actively embraced the folk Liang Zhu legend.By situating the ancient story of Zhu Yingtai in a contemporary context,the play replaces the traditional core values of“loyalty and righteousness”with modern themes of pursuing free love,amplifying women’s autonomy.Through a modern tragic love story,it achieves a classic reinterpretation of the classical folk legend.The“revised narrative”in A Storm primarily involves derivative adaptations,incorporating contemporary revisions to characters and themes.Its three-act structure also forms the foundational framework for subsequent reinterpretations of the Liang Zhu legend.The play demonstrates a conscious absorption of the rebellious spirit in folk literature,incorporates dialectal speech,and provides valuable insights into how modern literature can utilize oral traditions. 展开更多

Oral immunization is an alternative or supplementary approach that can significantly improve dog vaccination coverage,especially for free-roaming dogs.Safe and effective oral rabies vaccines for dogs are still being sought.In our previous studies,we generated a genetically modified rabies virus(RABV) ERA strain,rERAG_(333E),containing a mutation from arginine(Arg,R) to glutamic acid(Glu,E) at residue 333 of the G protein(G_(333E)).Our previous results demonstrated that rERAG_(333E) was safe for adult mice and dogs,and oral vaccination with rERAG_(333E) induced a strong and long-lasting protective immune response in dogs.Here,we further investigated the safety and immunogenicity of rERAG_(333E) in nontarget species,including suckling mice,rhesus monkeys,foxes,raccoon dogs,piglets,goats,and sheep.Suckling mice studies demonstrated that the G_(333E) mutation significantly reduced the virulence of the ERA strain.All of the suckling mice aged 10 days and above survived and showed no apparent signs of disease after intracerebral inoculation with rERAG_(333E).Animal studies demonstrated that rERAG_(333E) was safe in rhesus monkeys,foxes,raccoon dogs,piglets,goats,and sheep.None of those animals inoculated orally with 10 times the intended field dose of rERAG_(333E) showed abnormal clinical signs before and after the booster immunization with Rabvac 3,an inactivated rabies vaccine.Meanwhile,oral inoculation with rERAG_(333E) induced strong neutralizing antibody(NA) responses to RABV in rhesus monkeys,foxes,raccoon dogs,and piglets.These results demonstrated that rERAG_(333E) has the potential to serve as a safe oral rabies vaccine for dogs. 展开更多

This narrative review examines recent advances in salivary biomarkers for oral squamous cell carcinoma(OSCC),a major subtype of oral cancer with persistently low five-year survival rates due to delayed diagnosis.Saliva has emerged as a noninvasive diagnostic medium capable of reflecting both local tumor activity and systemic physiological changes.Various salivary biomarkers,including microRNAs,cytokines,proteins,metabolites,and exosomes,have been linked to oncogenic signaling pathways involved in tumor progression,immune modulation,and therapeutic resistance.Advances in quantitative polymerase chain reaction,mass spectrometry,and next-generation sequencing have enabled comprehensive biomarker profiling,while point-of-care detection systems and saliva-based omics platforms are accelerating clinical translation.Remaining challenges include variability in salivary composition,lack of standardized collection protocols,and insufficient validation across large patient cohorts.This review highlights the mechanistic relevance,diagnostic potential,and translational challenges of salivary biomarkers in OSCC. 展开更多

Background:The regulatory mechanisms governing vasculogenic mimicry(VM)in oral squamous cell carcinoma(OSCC)remain largely undefined.This study aimed to identify critical factors and elucidate the epigenetic mechanisms underlying VM in OSCC.Methods:Bioinformatics analysis was performed utilizing single-cell RNA-seq,bulk RNA-seq,and histone H3 lysine 27 acetylation(H3K27ac)Chromatin Immunoprecipitation(ChIP)-seq data obtained from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)databases.ChIP-qPCR was used to validate the binding of ETS transcription factor ELK4(ELK4)to the dihydrofolate reductase(DHFR)enhancer.In vitro VM formation and invasion of OSCC cells were assessed using Matrigel-based tube formation and Transwell assays,respectively.Results:Elevated expression of VM-related genes predicts unfavorable prognosis in OSCC patients.High-dimensional weighted gene co-expression network analysis(hdWGCNA)identified epithelial subcluster C4 as most strongly associated with VM and metastasis.Three co-expression modules within this subcluster exhibited significant positive correlations with both phenotypic traits.Among the 30 eigengenes from the three modules,DHFR emerged as a key regulator of VM and metastasis.Knockdown or inhibition of DHFR significantly suppressed VM formation and invasion in OSCC cells.Mechanistically,ELK4 activated DHFR transcription through direct binding to its enhancer.DHFR overexpression rescued VM and invasion impairment induced by ELK4 knockdown.Conclusion:DHFR was a pivotal enhancer-regulated gene driving VM and metastasis in OSCC.ELK4 directly binds to DHFR enhancer regions to activate its transcription,thereby promoting these malignant phenotypes.These findings identified the ELK4/DHFR axis as a promising therapeutic target for anti-angiogenic intervention in OSCC. 展开更多

Osmanthus fragrans is most famous for its strong aroma,and different varieties have different degrees of fragrance and color.Fragrance and color are important factors affecting the ornamental quality of O.fragrans.Terpenoids are important secondary metabolites in plants,with β-carotene(C40)being the major pigment substance and linalool(C10)being the key aromatic component in O.fragrans.The geranylgeranyl pyrophosphate synthase genes(GGPPSs)play important roles in secondary metabolism in plants.However,the functions of the GGPPS family in floral color and fragrance formation has rarely been reported in O.fragrans.In this study,24 Of GGPPS genes were identified and classified into two subfamilies.The Of GGPPSs showed tissue-specific expression and Of GGPPS13 had highest expression in flowers.The Of GGPPS13 protein was localized to chloroplasts.The transcriptome data of Of GGPPS13 was verified by q RT-PCR and the expression level in‘Wanyingui'with strong aroma was higher than that in‘Zhuangyuanhong'with deep color at different flower development stages.Transient overexpression of Of GGPPS13 in O.fragrans petals showed that Of GGPPS13 increased the β-carotene content,the main color substance of O.fragrans,but decreased the linalool content,the main volatile organic compound(VOC)in the floral aroma of O.fragrans.Of GGPPS13 was indicated as the critical gene related to terpenoid synthesis in the floral aroma and color formation in O.fragrans.Our findings provide gene resources on the GGPPS gene family for further revealing the molecular regulation mechanism of the floral color and aroma formation in O.fragrans. 展开更多

Optimal health during pregnancy is crucial for ensuring the well-being of the mother and the developing fetus.This article is focused on the impact of oral health and the role of personalized oral hygiene management in addressing prevalent dental issues among pregnant women,with particular emphasis on periodontal disease and dental caries.Despite the high prevalence of these dental problems and their association with obstetric complications such as pre-term birth and low birth weight,many pregnant women do not receive adequate dental care.This gap in care is often due to misconceptions about the safety of dental treat-ments during pregnancy and lack of awareness on the part of healthcare profes-sionals.Appreciations of the impacts of oral health and personalization of oral hygiene strategies such as tailored education and support,have proven effective in improving oral health in this population.Significant reductions in the incidence of caries and periodontal disease may be achieved by adapting care to the specific needs of each patient,thereby enhancing maternal and fetal health outcomes.Integration of personalized oral hygiene management into maternal health pro-grams and enhancement of ongoing education for pregnant women and healthcare professionals are essential steps in the reduction of pregnancy-related risks and improvement of maternal and neonatal well-being.Core Tip:In this article,we reviewed a recent study on the effects of personalized oral hygiene management on the oral health of pregnant women,as discussed in the article by Men et al.The study demonstrated that personalized oral hygiene interventions significantly improved oral health outcomes during pregnancy by reducing the prevalence of dental caries and periodontal disease.We emphasized the importance of individualized oral care programs that integrate education and tailored support,and we highlighted their significance in enhancing maternal and fetal health.This approach underscores the need for incorporating personalized oral hygiene management into routine prenatal care in order to optimize health outcomes.CONCLUSION This article emphasizes the critical role of personalized oral hygiene management in improving oral health during pregnancy.By tailoring oral care strategies to individual needs,significant improvements in dental health may be achieved,as evidenced by the reduced CAT scores observed in the experimental group in the study by Men et al[25].This personalized approach not only addresses common oral issues such as dental caries and periodontal disease but also underscores the broader implications for maternal and fetal health.Despite the positive results,there remains a gap in consistency in the application of oral health practices during pregnancy,partly due to misconceptions and lack of awareness among patients and healthcare providers.Future research should aim at validating these findings across diverse populations,investigating the impact of oral hygiene interventions at various stages of pregnancy,and evaluating their long-term effects on maternal and fetal health.Integrating personalized oral hygiene management into maternal health programs and promoting continuous education for pregnant women and healthcare professionals are essential steps toward enhancing overall health outcomes.By proactively managing oral health,the risks associated with pregnancy may be reduced while improving maternal and neonatal well-being. 展开更多

BACKGROUND One of the main characteristics of oral squamous cell carcinoma(OSCC)is that it metastasizes to cervical lymph nodes frequently with a high degree of local invasiveness.A primary feature of malignant tumors is their penetration of neighboring tissues,such as lymphatic and blood arteries,due to the tumor cells'capacity to break down the extracellular matrix(ECM).Matrix metalloproteinases(MMPs)constitute a family of proteolytic enzymes that facilitate tissue remodeling and the degradation of the ECM.MMP-9 and MMP-13 belong to the group of extracellular matrix degrading enzymes and their expression has been studied in OSCC because of their specific functions.MMP-13,a collagenase family member,is thought to play an essential role in the MMP activation cascade by breaking down the fibrillar collagens,whereas MMP-9 is thought to accelerate the growth of tumors.Elevated MMP-13 expression has been associated with tumor behavior and patient prognosis in a number of malignant cases.AIM To assess the immunohistochemical expression of MMP-9 and MMP-13 in OSCC.METHODS A total of 40 cases with histologically confirmed OSCC by incisional biopsy were included in this cross-sectional retrospective study.The protocols for both MMP-9 and MMP-13 immunohistochemical staining were performed according to the manufacturer’s recommendations along with the normal gingival epithelium as a positive control.All the observations were recorded and Pearson’sχ²test with Fisher exact test was used for statistical analysis.RESULTS Our study showed no significant correlation between MMP-9 and MMP-13 staining intensity and tumor size.The majority of the patients were in advanced TNM stages(III and IV),and showed intense expression of MMP-9 and MMP-13.CONCLUSION The present study suggests that both MMP-9 and MMP-13 play an important and independent role in OSCC progression and invasiveness.Intense expression of MMP-9 and MMP-13,irrespective of histological grade of OSCC,correlates well with TNM stage.Consequently,it is evident that MMP-9 and MMP-13 are important for the invasiveness and progression of tumors.The findings may facilitate the development of new approaches for evaluating lymph node metastases and interventional therapy techniques,hence enhancing the prognosis of patients diagnosed with OSCC. 展开更多

Cancer remains a major global health concern,with escalating incidence and mortality rates underscoring the urgent need for novel diagnostic and therapeutic strategies.Increasing evidence has identified the oral microbiota as a critical contributor to tumorigenesis,thereby expanding the understanding of cancer pathogenesis beyond conventional risk factors such as tobacco use and genetic predisposition.This review summarizes recent progress in elucidating the complex relationship between the oral microbiota and various malignancies,particularly oral squamous cell carcinoma,esophageal adenocarcinoma,and pancreatic ductal adenocarcinoma.Pathogenic bacteria,including Porphyromonas gingivalis and Fusobacterium nucleatum,have been implicated in promoting tumor progression through mechanisms involving chronic inflammation,the production of metabolic toxins,and immune evasion.The dysbiosis of the oral microbiota,often driven by lifestyle factors such as poor diet,tobacco use,and alcohol consumption,further exacerbates these carcinogenic processes.Emerging therapeutic approaches including probiotics,oral microbiota transplantation,and CRISPR-based bacterial editing are under investigation for their potential to restore microbial homeostasis and suppress pathogenic species.Additionally,saliva-based microbial biomarkers have shown promise for non-invasive cancer screening.The integration of multi-omics technologies and artificial intelligence-driven platforms is further advancing the development of precision oncology.This review aims to consolidate fragmented findings concerning the oral microbiota-cancer axis and address existing gaps in mechanistic understanding.The review’s significance lies in the translational potential of microbial research to clinical applications,offering opportunities to reduce the global cancer burden through early detection and microbiota-targeted therapies. 展开更多
