Xylella fastidiosa (Xf) is an insect-transmitted, xylem-limited bacterial plant pathogen that infects hundreds of plant species. This pathogen causes bacterial leaf scorch in southern highbush blueberry (Vaccinium corymbosum interspecific hybrids) in the southeastern United States, a disease that has not yet been reported elsewhere. Previously, a comparative genomic analysis of Xf and ancestral host species identified evolutionary events of gene gain and loss related to host range specificity. Here, by using a similar workflow, we identified two loci that are significantly found in blueberry-infecting strains. Locus_1088 included a hypothetical protein and a small part of the N-terminus of an orphan RelE toxin, while Locus_2741 was annotated as a hypothetical protein. Using a protocol based on natural competence, mutants were generated in three Xf subsp. multiplex strains from blueberry. Less biofilm, more planktonic growth, and increased twitching motility as compared to its wild-type (WT) were observed for the strain LA-Y3C_1088 mutant. In blueberry virulence assays, the LA-Y3C_1088 mutant caused significantly more severe symptoms than LA-Y3C_WT, whereas no significant differences were observed for other mutated strains. Interestingly the mutation of Locus_1088 additionally disrupted a toxin (part of a toxin-antitoxin system) that is likely responsible for the phenotypic changes observed. However, because the two independent mutants were not generated, we could not determine whether the phenotype resulted from disruption of hypothetical protein or the toxin. Additionally, since the coffee-isolated but never tested in blueberry Xf subsp. fastidiosa strain CFBP8073 was found to encode the two blueberry-associated loci studied here, its virulence was assessed in blueberry. This strain caused severe symptoms comparable to the control strain AlmaEm3 from blueberry. Due to the complexity of understanding host specificity in Xf, any advance in identifying genetic markers for host specificity in this devastating pathogen could greatly improve management of Xf worldwide.by Meirong Shan, Qian Guo, Ruofei Li, Ni Li, Yanhua Fu, Huanyu Qi, Ge Zhang, Qian Wang, Xingli Xu, Jinchuan Lai
Hypertension is one of the main causes of cardiovascular diseases worldwide, affecting over one billion people. Although aliskiren offers a valuable option for inhibiting the renin-angiotensin system, its safety profile in the real world remains insufficiently explored, especially for rare or under-recognized adverse events (AEs), which have not been fully clarified. Therefore, leveraging large-scale post-marketing surveillance data is crucial for identifying rare AEs and guiding safer clinical practice. This study aims to elucidate pharmacovigilance signals associated with aliskiren (an antihypertensive drug) by systematically analyzing the characteristics of adverse events (AEs) from the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database and WHO-VigiAccess database, which provides a reliable scientific basis for clinical practice and regulatory decision-making. We conducted a retrospective quantitative analysis of aliskiren-related AE reports from the aforementioned two databases, employing the Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-item Gamma Poisson Shrinker (MGPS) algorithms for signal detection. The results indicate that there were 5,596 and 5,549 aliskiren-related reports in the FAERS and WHO-VigiAccess databases, respectively. The median duration of these AEs during the observation period was 62 days, with an interquartile range (IQR) of 7–282 days. In both databases, signals for aliskiren were distributed across 28 System Organ Classes (SOCs), among which investigations, cardiac disorders, renal and urinary disorders, vascular disorders, and metabolism and nutrition disorders exhibited significant signals based on specific criteria applied across the four algorithms. A total of 607 preferred terms (PTs) with significant disproportionality signals were detected using the four algorithms, including potential AEs not previously well-documented, such as palpitations, myalgia, proteinuria, muscular weakness, pulmonary edema, and pollakiuria. This study not only confirms the known adverse reactions of aliskiren but also uncovers new potential risks, highlighting the importance of strengthening drug safety monitoring to enhance therapeutic efficacy and reduce the risk of adverse reactions. It provides valuable safety insights for physicians considering the use of aliskiren in the management of primary hypertension.by Mingming Pan, Yanhua Shen, Jiayu Wu, Chaonan Liu, Meihong Zhu, Zhengyu Zhou
This study aimed to investigate the therapeutic effects of ELASEM®Flex and ELASEM®ProFlex, two eggshell membrane (EM) products, on sodium iodoacetate (MIA)-induced osteoarthritis (OA) in rats. An OA model was established by a single intra-articular injection of MIA into the knee joint. After modeling, rats were administered diclofenac sodium, ELASEM®Flex, and ELASEM®ProFlex by gavage daily for 4 consecutive weeks. During the experiment, food intake, water intake, body weight, and plantar mechanical pain threshold (MPT) of rats were measured weekly. Serum levels of TNF-α, COX-2, IL-1β, and CTX-II were assessed at weeks 2 and 4. After 4 weeks, knee joints were harvested for histopathological examination (HE staining and Safranin-O fast green staining). Results indicated that knee joints of OA rats showed significant swelling, which was alleviated to varying degrees in all treatment groups. Both ELASEM®Flex and ELASEM®ProFlex significantly increased the MPT (P ®Flex and ELASEM®ProFlex can exert preventive and reparative effects on knee OA in rats by alleviating arthritis pain, inhibiting inflammatory factor expression, reducing type II collagen degradation, and promoting chondrocyte proliferation.by Sudim Sharma, Anjali Neupane, Dikshya Kandel, Pratibha Chalisay, Sabina Marasini, Budhi Setiawan, Deepak Chandra Bajracharya, Shyam Raj Upreti, Leela Khanal, Haruko Yokote, Chahana Singh, Kshitij Karki
BackgroundHome-Based Records (HBRs) are personal health documents intended to improve continuity of care and caregiver engagement across reproductive, maternal, newborn, and child health (RMNCH) services. In Nepal, both standalone (sHBR) and integrated (iHBR) models are implemented, yet comparative evidence on their utilization and implementation challenges is limited. This study examined utilization patterns and system-level barriers associated with sHBR in Madhesh Province and iHBR in Koshi Province.
MethodsWe conducted a comparative qualitative study with descriptive quantitative profiling between May 17 and August 27, 2024. A total of 100 semi-structured in-depth interviews were completed with caregivers, health workers, Female Community Health Volunteers, and program managers across two provinces. The study applied “kuragraphy,” an ethnographic approach integrating interviews and field observations to construct contextual case narratives. Socio-demographic data were analyzed descriptively using the statistical package for the social Sciences (SPSS). Informed by the Human Centered Design (HCD) approach, the qualitative data were thematically analyzed in Excel using the Journey to Health and Immunization (JTHI) framework.
ResultsCaregivers widely perceived HBRs as essential documents, primarily for immunization tracking and future service access. The iHBR was viewed as more comprehensive and user-friendly, particularly due to its illustrations, which improved comprehension among low-literacy users. However, understanding remained limited among illiterate and marginalized populations. Family involvement in record management was minimal and largely confined to mothers. Implementation barriers included inadequate training – particularly for iHBR use, limited decision-making authority among frontline health workers, incomplete documentation of non-immunization components, poor material quality of sHBR, and concerns regarding the sustainability of donor-supported iHBR initiatives.
ConclusionHBR utilization in Nepal is shaped by caregiver literacy, gender dynamics, and health-system readiness. Strengthening training, supportive supervision, user-centered design, and sustainable supply mechanisms will be essential to optimize HBR effectiveness and support equitable RMNCH service delivery.

Equine asthma is a chronic, non-infectious inflammatory disease of the lower airways in horses, classified as mild to moderate (MEA) or severe (SEA). Its pathogenesis is not fully understood and is influenced by environmental and seasonal factors. In this cross-sectional study, seasonal effects on the bronchoalveolar lavage fluid (BALF) metabolome were investigated in asthmatic and non-asthmatic horses. The metabolome of 230 BALF samples from horses across different seasons, classified as cytologically unremarkable (CUA), MEA, or SEA, was analyzed using proton nuclear magnetic resonance spectroscopy (1H-NMR). Principal component analysis was performed for each season, and metabolite profiles were statistically compared between seasons within each group. Altered metabolites were subjected to pathway enrichment analysis using the FELLA R package. Asthmatic horses showed significant seasonal changes in metabolite concentrations between warm and cold seasons, whereas only trends were observed in CUA horses. Pathway analysis indicated enrichment of cholesterol metabolism across all groups. The mTOR signaling pathway was only enriched in SEA horses. Several metabolites—including valine, taurine and carnitine —were altered during the transition from winter to spring in asthmatic horses. These findings indicate that the winter to spring transition significantly modulates the airway metabolome in asthmatic horses, particularly in SEA-affected animals.by Tadgh Connery, Sofija Kukulite, Conor Farrell, Rosa Horgan, Karen Barry, Megan Doyle, Annalisa Setti, Mike Murphy
BackgroundDeath anxiety is fast becoming recognised as a transdiagnostic construct across myriad mental health conditions. Though existing clinical treatments of death anxiety, such as Cognitive Behaviour Therapy type interventions, have been shown to be effective, Terror Management Theory (TMT) proposes self-esteem as a protective factor against death anxiety by endowing individuals with a feeling of significance in life and helping them to process the nature of death and its inevitability. Despite the centrality of self-esteem to TMT, however, extant research examining its relationship with death anxiety has yet to be synthesised. The current study aims to systematically review peer-reviewed, quantitative research examining the association between death anxiety and self-esteem and, where possible, to test the strength of these associations through meta-analysis.
MethodA systematic search of quantitative and mixed-methods studies will be conducted across six databases: MEDLINE; PsycINFO; PubMed; Web of Science; CINAHL and; EMBASE. Google Scholar will also be searched and the first 200 records by relevance will be screened for eligibility. Searches will be conducted by TC, and records will be screened by TC, SK, CF, RH and KB, so that each record is screened for eligibility by at least two authors. Data extraction and quality assessment, using the Joanna Briggs Inventory Risk of Bias tools, will be performed by TC, SK, CF, RH and KB, so that each record is assessed by at least two authors, with doubts and discrepancies being resolved through discussion with AS and MM. A narrative synthesis of relevant data will be presented and, where sufficient data are available, meta-analysis will be conducted using the MAJOR extension for Jamovi to establish an overall effect size for the association between death anxiety and self-esteem. Should sufficient data be available, demographic factors, such as gender and age, and clinical population status (clinical vs. non-clinical population) will be examined as moderators of the effect. This protocol was developed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and has been registered in PROSPERO (CRD42024591775).
DiscussionThe current review will systematically examine the relationship between death anxiety and self-esteem. Should sufficient data be available, an overall effect size of the relationship will be generated. By better understanding how death anxiety is related to self-esteem, and by establishing the size and significance of the relationship will aid firstly in systematically validating TMT and, secondly, identify whether self-esteem may be targeted in future death anxiety interventions to reduce death anxiety and improve individuals’ overall mental health.

Cancer remains a leading cause of mortality worldwide and a significant barrier to improving quality of life across all populations. The protein kinase D family, including PRKD3, has been demonstrated to play a crucial role in cancer development through its involvement in regulating key cellular processes. Although growing evidence highlights the role of PRKD3 in the tumorigenesis of certain cancers, a comprehensive pan-cancer analysis of PRKD3 remains unavailable. To address this, we performed an integrative pan-cancer analysis of PRKD3 using multi-omics datasets from The Cancer Genome Atlas, the Genotype-Tissue Expression project, and cBioPortal. We examined PRKD3 expression, copy number variation, mutation, and DNA methylation, and evaluated their associations with clinicopathological features, patient survival, and diagnostic potential across 33 cancer types. Immune relevance was further assessed through correlations with immune infiltration, checkpoint gene expression, and immunotherapy response-related genomic biomarkers. Our results revealed that PRKD3 expression was highly heterogeneous, showing significant upregulation in liver cancer, gastric cancer, and adrenocortical carcinoma, and downregulation in others. Elevated expression was consistently associated with poor prognosis and increased stromal, neutrophil, and cancer-associated fibroblast infiltration in adrenocortical carcinoma, liver cancer, and stomach cancer, whereas paradoxical associations with favorable outcomes were observed in kidney clear cell carcinoma. PRKD3 expression also correlated with immune checkpoint molecules including PD-1, PD-L1, and CTLA-4, supporting an immunosuppressive role, while context-dependent associations with TMB and MSI highlighted its potential influence on tumor immunogenicity and responsiveness to immune checkpoint blockade. Collectively, these findings identify PRKD3 as a potential context-dependent modulator of tumor biology, prognosis, and immune interactions, underscoring its potential as a biomarker of diagnostic, prognostic, and therapeutic relevance in precision oncology.by Tomoo Hidaka, Takeyasu Kakamu, Hideaki Kasuga, Yuko Suzuki, Toshihiro Terui, Shizuka Kawamoto, Tatsuya Sato
Municipal government officials (MGOs) have played key roles in managing decontamination project of radioactive materials in the aftermath of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. However, the subjective distress experienced by MGOs during the decontamination project, mainly stemming from challenges in coordination with the national government, is not yet fully documented. The purpose of this study is to descriptively understand the nature and causes of subjective distress among MGOs and to make an exploratory conceptual model of the process through which such subjective distress becomes manifest. Narratives from three MGOs were collected through interviews and subjected to qualitative analysis using the Steps for Coding and Theorisation method. For the first purpose, the results indicate that inconsistencies in national reconstruction and decontamination designs impose substantial burdens at the operational level; these burdens are further amplified by inadequate management by national authorities, and subjective distress emerges through a breakdown of trust among national government officials, municipalities, and residents. For the second purpose, an exploratory conceptual model explaining the progression toward subjective distress through the following four stages was created: the emergence of distrust and adversarial orientations toward the national government, the dilemma of occupying an intermediate position, the erosion of ties with residents, and the threat to professional pride. Overall, through experiences such as questioning the national government’s reconstruction policies, enduring the psychological burden of occupying an intermediate position, and witnessing a breakdown in trust with residents, MGOs may find their professional pride undermined; consequently, subjective distress, manifesting as a profound sense of emptiness, may arise. As MGOs are likely to stand at the frontline of managing post-radiation-disaster reconstruction and decontamination efforts, it is essential to develop protective measures for their mental health from both macro-level, organisational perspectives and micro-level, occupational and psychological perspectives.by Aino Kitayama, Yu-Tai Liu, Ai Shibata, Sayaka Kurosawa, Koichiro Oka
BackgroundChronic musculoskeletal pain is a significant symptom among workers. 24-hour movement behaviours comprising sleep, sedentary behaviour, light-intensity physical activity, and moderate-to-vigorous-intensity physical activity are associated factors. However, the relationships between these behaviours and workers’ chronic musculoskeletal pain, considering the interrelationship between the behaviours, are still unclear. This study aimed to investigate the associations of 24-hour movement behaviours with workers’ low-back and neck/shoulder pain.
MethodsIn 2023, cross-sectional survey was conducted targeting adults who registered for a Japanese Internet survey system. Time for 24-hour movement behaviours and other demographic characteristics (age, gender, marital status, education, household income, height, weight, smoking, alcohol, chronic disease, work hours, and job activity) were self-reported. The intensity of low-back and neck/shoulder pain was evaluated using the numerical rating scale and a score of ≥4 was considered as moderate-to-severe pain. Compositional logistic regression and isotemporal substitution were performed to examine the associations of 24-hour movement behaviours and time reallocations between the behaviours with moderate-to-severe low-back and neck/shoulder pain, adjusted for all the demographic variables.
Results1,665 full-time workers (women: 35.8%, mean age: 42.1 ± 10.2 years) were analysed. Increased sleep and decreased light-intensity or moderate-to-vigorous-intensity physical activity were associated with lower odds of moderate-to-severe low-back (adjusted odds ratio [AOR] = 0.54, 95% confidence interval [CI] = 0.40–0.72; 1.45, 1.25–1.69; 1.17, 1.06–1.30, respectively) and neck/shoulder pain (AOR = 0.60, 95% CI = 0.45–0.80; 1.37, 1.19–1.60; 1.12, 1.01–1.24, respectively). Reallocating sleep from the other behaviours was associated with decreased probabilities of low-back and neck/shoulder pain, whereas replacing sedentary behaviour or light-intensity physical activity with more intense activity was associated with increased probabilities. However, the results of moderate-to-vigorous-intensity physical activity reallocation were no longer significant when restricted to complete cases.
ConclusionsConsidering the interrelationship of 24-hour movement behaviours, sleep was favourably associated with workers’ low-back and neck/shoulder pain.

The increasing occurrence of microplastics (MPs) in organic waste streams raises concerns about their impact on anaerobic digestion (AD). This study examined the effect of polypropylene MPs (PP-MPs) on methane production during AD of food waste for 150 days under batch conditions. PP-MPs were added at 10–300 mg g-1 total solids (TS), covering reported MP levels in food waste and food packaging materials and extending to worst-case scenarios. Methane yields ranged from 310.2 to 324.4 mL CH4 g-1 volatile solids (VS) across treatments versus 334.3 ± 5.2 mL CH4 g-1 VS in the control, with no significant differences (p = 0.634). Kinetic modeling confirmed no consistent inhibitory trends. FTIR and SEM analyses indicated minor surface oxidation and cracking on PP-MPs, while the polymer backbone remained intact, suggesting only superficial aging. These results provide critical assurance for waste-to-energy facilities processing plastic-contaminated organic waste streams. Although PP-MPs do not impair AD performance, their persistence and potential fragmentation pose environmental risks. These findings provide critical insight into the resilience of AD systems and emphasize the need for strategies to mitigate secondary MP formation in biogas production from contaminated waste streams.by Makiko Sasaki, Mamoru Tanaka, Akihiro Nomoto, Ryusei Yamasaki, Tomokazu Yoshimura, Shigenobu Yano, Yasunari Sasaki, Yuki Kojima, Taketo Suzuki, Hirotada Nishie, Keiji Ozeki, Takaya Shimura, Eiji Kubota, Hiromi Kataoka
Photodynamic therapy (PDT) is an anti-cancer therapy that employs a photosensitizer (PS) and an optimal wavelength of light, causing a photochemical reaction that releases reactive oxygen species, thereby inducing cancer cell death via oxidative stress. Because light irradiation is limited to the tumor site, PDT has minimal adverse effects. The cancer cell selectivity of the PS is important for reducing damage to the normal mucosa caused by scattered light. Antibody-drug conjugates (ADC) are novel anti-cancer therapies that combine a monoclonal tumor-surface-receptor-targeting antibody with a drug bonded through chemical linkers. ADCs enable the targeted delivery of a variety of drugs to cancer cells while minimizing their delivery to healthy tissues. One such tumor surface receptor is the human epidermal growth factor receptor 2 (HER2), which is of interest in the treatment of many cancers, including gastrointestinal cancer. To improve tumor selectivity and minimize damage to the mucosa surrounding the tumor in PDT, we established a novel PS glucose-linked chlorin e6-conjugated trastuzumab (G-Ce6-trastuzumab) that is conjugated to existing PS glucose-linked chlorin e6 (G-Ce6) and evaluated its anti-cancer effect compared to G-Ce6. The effect of PDT was evaluated using HER2-high-expression cells NCI-N87 and HER2-low-expression cells MKN-45. G-Ce6-trastuzumab is internalized by the intracellular organelles in cancer cells. Evaluation of cell death using the WST-8 assay also demonstrated a significantly higher cytotoxic effect of G-Ce6-trastuzumab in HER2-high-expression cells compared with conventional PS G-Ce6. Thereby, G-Ce6-trastuzumab may be an excellent novel PS for PDT because of its strong selectivity for HER2-high-expression cells.by Verner N. Orish, Renosten E. Tetteh, David Adzah, Chinecherem A.

BackgroundToxoplasma gondii (T. gondii) is a successful protozoan parasite infecting up to a third of the human population. It has varied transmission routes including ingestion of food and water contaminated by cat feces containing oocysts of the parasite and ingestion of bradyzoites in poorly cooked meat. Blood transfusion is another possible route of transmission especially among people with medical conditions requiring blood transfusion, such as those with sickle cell disease (SCD). This study aimed at finding out the prevalence of T. gondii infection and the association of blood transfusion among patients with SCD.
MethodThis study was a cross-sectional study involving SCD patients attending the SCD clinic at the Ho Teaching Hospital in the Volta Region of Ghana. Questionnaire administration was employed to obtain sociodemographic information, cat ownership, consumption of poorly cooked meat, as well as blood transfusion history. A blood sample was collected and anti-T. gondii IgG and IgM were detected using Rapid Diagnostic Test (RDT), while Enzyme-linked Immunosorbent Assay (ELISA) was used as the gold standard and reference. Seropositivity was defined as either positive for IgG, IgM or both. Data was analyzed using SPSS version 23, with frequency distribution done for the sociodemographic variables and the prevalence of RDT and ELISA anti-T. gondii IgG and IgM. Pearson Chi-square analysis was performed to find any significant association between diagnosis of T. gondii infection with sociodemographic variables and blood transfusion. Logistic regression analysis was performed to investigate the odds of seropositivity (ELISA) with sociodemographic variables and blood transfusion.
ResultsA total of 156 SCD patients participated in this study of which 124 (79.5%) and 32(20.5%) were HbSS and HbSC respectively. Among the study participants, 105 (67.3%) had a history of blood transfusion. A total of 60 (38.5%) and 83 (53.2%) patients were positive for RDT and ELISA respectively. No significant association was seen between T. gondii diagnosis and cat ownership (RDT,20[37.7%], p = 0.891; ELISA, 27[50.9%], p = 0.673) and consumption of poorly cooked meat (RDT,37[41.6%],p = 0.370;ELISA,53[59.6%], p = 0.211). However there was a significant association between T. gondii diagnosis and age, with seropositive results predominantly seen among older patients (≥20 years) (RDT, 38[52.1%], p = 0.002; ELISA 49 [67.1%, p = 0.002]. Blood transfusion had a significant association with T.gondii diagnosis (RDT, p = 0.003; ELISA, p = 0.001). A total of 66 (62.9%) of SCD patients who had history of blood transfusion tested positive for ELISA and they had 3 times the odds of testing positive for ELISA (adjusted OR 3.14[95% CI 1.50–6.58]; p = 0.002).
ConclusionThe prevalence of T. gondii infection was higher by ELISA (53.0%) than by rapid diagnostic testing (RDT) (38.5%), and sickle cell disease patients with a transfusion history had higher odds of seropositivity. These findings highlight the need to strengthen transfusion safety protocols and consider screening strategies for T. gondii among high-risk populations such as patients with sickle cell disease. Also, there is the need for longitudinal research to help elucidate the true contribution of blood transfusion transmission of T. gondii since a cross-sectional study, causality could not be established.

ObjectivesPost-prostatectomy patients experience urinary incontinence, fluctuating quality of life, and psychosocial distress during early survivorship. Evidence-based nursing models addressing long-term supportive needs remain limited. This study developed and evaluated an enhanced survivorship-oriented care model designed to improve postoperative functional recovery and quality-of-life outcomes.
MethodsA retrospective study was conducted at a tertiary urologic center. The improved survivorship model was developed based on our previous PROSTATE care model, integrating nurse-led continuous follow-up, psychosocial support, and structured rehabilitation. A total of 1062 patients who underwent radical prostatectomy between June 2024 and May 2025 received the enhanced survivorship care, compared with 673 patients treated between June 2023 and December 2023 under the previous PROSTATE care model. Outcomes included urinary continence, quality of life, postoperative complications, and length of stay. Between-group comparisons were performed using independent-samples tests, and repeated-measures ANOVA was applied to assess longitudinal changes.
ResultsBoth groups demonstrated significant improvements in urinary recovery and quality of life over time (time × group interaction, P Conclusion
The enhanced survivorship care model demonstrated clinically meaningful improvements in quality of life and continence recovery, while maintaining patient safety. These findings support its clinical value and potential for wider implementation as a structured survivorship strategy following radical prostatectomy.

Hepatocellular carcinoma (HCC) has a very significant mortality rate and is one of the most common cancers worldwide. Jacaranda mimosifolia is reported to have potential antitumor activities against various human cancers. However, the effects of J. mimosifolia on HCC are yet elusive. This study aimed to investigate the anti-HCC potential of methanolic extract of J. mimosifolia leaves using in vitro and in vivo studies and a network pharmacology approach. The effect of J. mimosifolia extract was assessed on Huh-7.5 cells using MTT assay, wound healing assay, and DNA fragmentation assay. These experiments found that J. mimosifolia extract significantly suppressed Huh-7.5 cell proliferation, impaired cell migration, and induced cell apoptosis. The real-time PCR validated the upregulation of p53 and Bax, alongside the downregulation of AFP and GPC3 in Huh-7.5 cells after treatment with J. mimosifolia extract. In vivo experiments confirmed the hepatoprotective effects of J. mimosifolia extract in mice models with CCl4-induced hepatic injury. In addition, through network pharmacological analysis, J. mimosifolia was found to play a critical role against HCC via targeting multiple potential targets and pathways. Docking analysis identified apigenin and kaempferol with the lowest binding energy against PTGS2 and EGFR, respectively, while flavonol glycoside showed the lowest binding energy against MMP9. However, detailed research is needed to isolate the potential phytochemicals from J. mimosifolia against HCC.by Sandra A. Allan
Cornsilk flies, Euxesta eluta and Chaetopsis massyla (Diptera: Ulidiidae), are serious economic pests affecting sweet corn production in Florida. As a basis for development of enhanced trapping strategies, the sensory and behavioral basis for response to color was examined. Using electroretinograms, spectral sensitivity curves for both species revealed broad curves with a peak in the UV (350 nm) and the green region (500–550 nm) of the spectrum. Curves for males and females of each species were relatively similar in shape. Using pigment templates, the measured curve for E. eluta was matched by pigment combinations with maximum sensitivity at 350, 430, 500 and 560 nm in a ratio of 25:21:25:29. Similarly, the curve for C. massyla was best matched by pigments with maximum sensitivity at 350, 430, 500 and 560 nm in a 28:18:27:27 ratio. Laboratory behavioral assays were conducted to evaluate if attraction occurred in response to the color or the brightness of a target. Attraction responses were evaluated in paired tests to blue, green and yellow cards paired with gray cards of matching brightness. Despite relatively similar visual pigments, the two species differed greatly in their behavioral attraction. Euxesta eluta was only attracted to yellow cards at low or high brightness levels, to mid-level bright blue cards and not attracted to green cards at any brightness level. In contrast, C. massyla was highly attracted to yellow and green cards compared to gray cards of the same brightness but avoided blue cards. These differences in response to color and brightness are important for interpretation of surveillance results as well as development visual traps targeted for these species.Chagas disease affects millions of individuals across Latin America and imposes a substantial economic burden on healthcare systems, particularly in rural and underserved regions. Chronic Chagasic cardiomyopathy remains one of the leading causes of heart failure-related mortality in endemic countries. Tissue inhibitor of metalloproteinases-1 (TIMP-1) has emerged as a potential biomarker of myocardial fibrosis in cardiomyopathies. This study was designed to investigate the association between TIMP-1 and myocardial fibrosis in chronic Chagas disease and to assess its potential as an early biomarker of fibrotic remodelling.

To synthesise the prevalence and patterns of dementia-relevant structural brain MRI abnormalities in adults with suspected or confirmed dementia in low- and middle-income countries (LMICs), and to summarise MRI protocols and the incremental diagnostic contribution of MRI beyond cognitive screening.
Systematic review and meta-analysis.
PubMed, EMBASE, Web of Science and PsycINFO (January 1990–27 January 2025), plus reference list screening and targeted manual searches.
Observational or diagnostic-accuracy studies from World Bank-defined LMICs including adults (≥50 years) with suspected or confirmed dementia who underwent brain MRI as part of diagnostic evaluation.
Two reviewers independently screened, extracted data and assessed risk of bias using ROBINS-I. Random-effects models pooled prevalence of dementia-relevant MRI abnormalities; diagnostic-accuracy outcomes were synthesised narratively due to heterogeneous reference standards and incomplete reporting.
39 LMIC studies were included; 23 studies (2513 participants) contributed to the meta-analysis. Dementia-relevant MRI abnormalities (defined as ≥1 clinically relevant structural abnormality per study definition) were present in 1248/2513 participants. The pooled prevalence of dementia-relevant MRI abnormalities was 58% (95% CI 43% to 72%), with substantial heterogeneity (I²=95%) and a wide prediction interval (8–96%), indicating marked between-study variability; this estimate should be interpreted as a descriptive summary of study-level proportions rather than a precise population parameter.
Brain MRI frequently demonstrates dementia-relevant pathology in LMIC clinical cohorts, usually with mixed neurodegenerative-vascular patterns. Structured visual ratings may add aetiologic specificity beyond cognitive screening, but pooled estimates should be interpreted as summaries of heterogeneous study-level findings rather than precise population parameters, given high heterogeneity and risk of bias.

To investigate the association between quantitative retinal vascular parameters and coronary artery disease (CAD) and to evaluate the efficacy of a retinal phenotype-based diagnostic model as a non-invasive tool for early CAD screening.
A retrospective cross-sectional study.
A single-centre study conducted at the Cardiovascular Center of Beijing Tongren Hospital, Capital Medical University, China, between January and October 2024.
417 patients with suspected angina undergoing their first coronary angiography (CAG) were enrolled. Inclusion criteria were age >18 years and high-quality fundus photography within 24 hours pre-CAG. Major exclusions were prior coronary interventions, severe systemic/valvular heart diseases and ocular conditions impairing retinal vascular visualisation.
The primary outcome was the association between quantitative retinal vascular parameters and the presence of CAD (defined as ≥50% stenosis). Secondary outcomes included the diagnostic performance area under the receiver operating characteristic curve (AUROC) of three predictive models: one based on quantitative retinal vascular parameters alone, one based on traditional risk factors and a combined model integrating both retinal and clinical variables.
This study enrolled 417 patients undergoing initial CAG. Compared with non-CAD controls (n=190), patients with CAD (n=227) had higher prevalence of hypertension, dyslipidaemia and diabetes, along with elevated levels of fasting blood glucose, lipoprotein(a) (Lp(a)), triglyceride (TG) and glycated haemoglobin (HbA1c) (all p
Our findings, derived from an artificial intelligence-based fully automated quantitative retinal vascular parameters measurement method, revealed that multiple quantitative fundus parameters—including FD, VD and other morphological parameters were significantly associated with CAD risk. The CAD diagnostic model we developed demonstrates strong performance and high interpretability, making it suitable for early CAD screening and diagnosis.
