DeepLabCut-based automated system reveals diverse temperature tolerance among medaka strains and related Oryzias species.

Temperature is a critical environmental factor influencing the physiology and behavior of ectothermic animals, yet conventional methods for evaluating thermal tolerance in fish rely on subjective manual observation of loss of equilibrium (LOE), limiting experimental throughput and introducing observer bias. Here, we developed an automated temperature tolerance evaluation system integrating DeepLabCut-based pose estimation with custom image processing algorithms to objectively quantify the timing of LOE during thermal stress tests. Our system incorporated region partitioning and color transformation preprocessing to improve keypoint detection accuracy, followed by a classification model combining ResNet34-based frame features with keypoint coordinates to objectively determine the timing of LOE without manual observation. Validation against manual annotation showed that the automated system achieved an accuracy comparable to the natural variability between trained investigators, and outperformed naive human observers, supporting its validity as an objective and reproducible alternative to manual scoring. Using this system, we characterized cold and heat tolerance across six medaka strains (Oryzias latipes: d-rR/TOKYO, HB11A, OK-Cab, HO5 and HdrR-II1; O. sakaizumii: HNI-II). Cold and heat tolerance assessment revealed inter-strain variation, with HdrR-II1 among the most cold- and heat-tolerant strains and HNI-II the least tolerant of both cold and heat stress. We further evaluated cold tolerance in medaka-related species (O. sinensis, O. cabaranensis, O. curvinotus, O. luzonensis, O. celebensis, and O. javanicus) and zebrafish (Danio rerio), revealing substantial interspecific variation that broadly corresponded with latitudinal distribution. O. latipes, distributed at the highest latitudes among the tested species, exhibited the greatest cold tolerance, whereas O. celebensis, O. javanicus, and other tropical or low-latitude species showed comparatively low cold tolerance. Our automated system provides a robust, high-throughput platform for thermal tolerance evaluation and, combined with the genetic and genomic resources available in medaka, establishes a foundation for elucidating the molecular mechanisms underlying temperature adaptation in fish.

Decoding spatiotemporal fibrotic and cellular immunosuppression of therapeutic T cells in live pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDA) is profoundly immunosuppressive. To help define this behavior, we present integrated experimental and computational frameworks to elucidate therapeutic T cell dynamics. Through the development of TME-CARTographer (TME-CART), a computational pipeline integrating high-dimensional data, graph theory, behavior analysis, and deep learning (DL), we present quantitative insights on 4D T cell-TME interactions in live PDA tumors. Mapping physical immunosuppression demonstrates that collagen fiber architectures direct migration while concomitantly limiting off-axis movement, creating immune exclusion zones. Expanding these findings, we establish that the collagen matrix harbors and spatially organizes immunosuppressive myeloid cells to serve as cooperative co-modulators of T cell behaviors, including migration, sampling, repulsion, and sequestration. Consistent with these findings, DL defines both linear and nonlinear collagen matrix and cellular neighborhood interactions as drivers of T cell behavior. The TME-CART DL framework also accurately predicts shifts in immunosuppression following depletion of myeloid cells. Overall, we identify synergistic barriers impeding anti-tumor T cell behaviors and present TME-CART as a discovery platform for interpreting complex 4D data to enhance the understanding and design of immunotherapies.

Body mass index-specific nanoparticle protein corona signatures in late pregnancy.

The protein corona (PC) formed on the surface of nanoparticles (NPs) upon exposure to human biofluids is a dynamic interface that reflects the physiological and pathological status of the host. In this study, we investigated how the maternal body mass index (BMI) influences the composition of the NPs' PC during late pregnancy. Polystyrene NPs were incubated with plasma samples collected from third-trimester pregnant individuals across normal weight, overweight, and obese BMI categories. Comprehensive characterization using dynamic light scattering (DLS), zeta potential measurements, and transmission electron microscopy (TEM) confirmed BMI-dependent differences in PC thickness and colloidal stability. SDS-PAGE and label-free quantitative proteomics revealed distinct molecular compositions: PCs from obese individuals were enriched in inflammatory and lipid metabolism-associated proteins (e.g., APOE and CRP), while normal weight-derived PCs showed higher levels of complementary regulators and extracellular matrix proteins. Principal component analysis (PCA) demonstrated clear clustering of proteomic profiles by the BMI group, suggesting BMI-specific PC fingerprints. These findings indicate that the maternal metabolic phenotype shapes nano-bio interactions at the proteomic level and highlight the potential of PC profiling as a non-invasive approach for assessing maternal health and metabolic status. This work lays the foundation for integrating NP-based proteomics into precision nanomedicine for maternal-fetal health monitoring.

Treatment Decisions in Multiple Myeloma.

Revolutions in transplantation and targeted and immune therapies have transformed multiple myeloma from a disease with an associated survival of a few years into one for which functional cure is an emerging goal. This abundance of effective therapies has created clinical complexity. Here we provide a practical framework, anchored in trial evidence and informed by emerging biologic discoveries, for the navigation of treatment decisions across the disease spectrum. We outline how cytogenetic and genomic risk stratification, functional fitness, and measurable residual disease status individualize therapy in newly diagnosed disease, in which quadruplet induction therapy is now standard and the role of autologous transplantation is being reevaluated. Regarding relapse, we address the sequencing of B-cell maturation antigen-directed chimeric antigen receptor (CAR) T cells, bispecific antibodies, and antibody-drug conjugates, emphasizing T-cell fitness and multiantigen targeting to counter exhaustion and antigen escape. We also consider early interception in high-risk smoldering myeloma. Throughout, we underscore that enrollment of patients in clinical trials should be considered in order to ensure continued progress.

Mapping the development pipeline of genomic point-of-care tests: a horizon scan.

INTRODUCTION: As precision medicine increasingly relies on genetic information, the development of reliable genomic point-of-care tests (POCTs) is essential. However, the number of technologies that have reached true clinical usability is limited. There is a growing need for POCTs that enable rapid, accurate analysis of human genetic variation, particularly across diverse clinical settings without requiring specialist expertise. AREAS COVERED: This horizon scan aimed to provide an overview of the development pipeline of POCTs to identify variation(s) in the genome and epigenome that enable the use of genetic information to inform diagnosis, prognosis, and treatment decisions in any clinical area. Database (Embase and MEDLINE) and clinical trial registry (ClinicalTrials.gov) searches were conducted from 2019 to 19 December 2024; 346 unique technologies were identified. EXPERT OPINION AND COMMENTARY: A range of purposes and conditions were identified; the most common being diagnosis (n = 263) and cancer (n = 237) respectively. We defined 'true POCTs' as those that were highly automated, capable of analyzing complex samples, and operable by non-specialists. Only 36 met these criteria; six are already on the market, one is in clinical trials, and the remaining 29 are at various stages of development. Overall, most technologies were in early stages of development, highlighting the need for further innovation and validation.

Autophagy activation in granulosa cells as a mechanism of astaxanthin action: evidence from a pilot randomised trial in PMOS-associated infertility.

Astaxanthin (AST) has been reported to influence oxidative stress, endoplasmic reticulum stress, and apoptosis in women with polyendocrine metabolic ovarian syndrome (PMOS), formerly referred to as polycystic ovary syndrome (PCOS), but its effects on granulosa-cell (GC) autophagy remain unclear. Given the central role of autophagy in follicular development, this triple-blind, placebo-controlled pilot randomised trial evaluated whether AST modulates autophagy-related signalling in GCs and how these molecular effects relate to ovarian response. Fifty women with PMOS-related anovulatory infertility were enrolled between November 2023 and September 2024 and received AST (12 mg/day) or placebo for six weeks prior to oocyte retrieval; forty-four completed the study (21 AST, 23 placebo). Primary exploratory endpoints were molecular markers of adenosine monophosphate-activated protein kinase (AMPK)-autophagy signalling, and primary clinical outcomes included ovarian response indicators and cleavage stage embryo quality. AST supplementation increased autophagy-related gene 7 (ATG7) expression, enhanced autophagy flux, reduced apoptosis, and showed a trend toward increased AMPK activation. Before adjustment, AST improved oocyte maturity rate (OMR) and increased mature (metaphase II; MII) oocyte yield. After adjusting for age, body mass index, and anti-mullerian hormone level, total oocyte and MII oocyte yields remained significantly higher with AST, while OMR became non-significant. Among embryology outcomes, both the top-ranking embryo rate and the number of embryos suitable for cryopreservation were significantly higher with AST after adjustment. Pregnancy outcomes were numerically higher but not statistically significant. This pilot trial suggests that AST activates autophagy- and apoptosis-related pathways in GCs and may enhance oocyte competence and embryo quality in PMOS. Larger studies are needed to confirm these mechanistic and clinical effects.

Conserved miRNA regulators of PD-1/PD-L1 in glioblastoma and colorectal cancer.

Immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 axis have transformed cancer therapy, but their efficacy remains limited in glioblastoma (GBM) and heterogeneous in colorectal cancer (CRC). MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level, including immune checkpoint molecules, yet conserved regulatory miRNA networks across distinct cancers remain poorly defined. Five conserved miRNAs (miR-106a-5p, miR-106b-5p, miR-20a-5p, miR-20b-5p, miR-138-5p) fulfilled the selection criteria and were consistently dysregulated in GBM and CRC. MiR-106a-5p and miR-106b-5p were upregulated in both cancers and showed favourable prognostic associations, with higher expression correlating with improved survival. miR-20a-5p and miR-20b-5p were preferentially expressed in microsatellite-stable (MSS) CRC and correlated with favourable outcomes in both cancers, whereas miR-138-5p was downregulated in both tumours compared to normal tissue, but showed opposite survival associations, with higher levels linked to worse prognosis. Correlation analysis revealed significant inverse associations between several miRNAs and checkpoint gene expression, including moderate inverse correlations for CD274-miR-106a-5p in GBM, CD274-miR-20a-5p in CRC and PDCD1LG2-miR-20a-5p in both cancers. Pan-cancer profiling demonstrated broad and heterogeneous dysregulation, with expression absent in ovarian cancer for four of the five miRNAs. Pathway enrichment implicated the TGF-β, Hippo, FoxO, and cell cycle pathways, consistent with their known roles in tumour immune evasion. We identified a conserved set of miRNAs that are dysregulated in both GBM and CRC, correlate with survival, and display inverse relationships with PD-1/PD-L1/PD-L2 expression. These miRNAs represent candidate regulators of the PD-1/PD-L1/PD-L2 axis and potential biomarkers of tumour biology that may influence immune checkpoint signalling.

Creatine formulations and repeated sprint training: effects on physical and physiological adaptations in soccer players during the short-term preparation phase.

BACKGROUND: This research examined the impact of various creatine (Cr) supplementation formulations during a 4-week preparatory phase on the efficacy of repeated sprint training (RST) and on improvements in physical and physiological performance in male soccer athletes. METHODS: A total of forty collegiate young soccer players volunteered for the study. They were randomly divided into four groups: creatine monohydrate (Cr-Mon, n&#x2009;=&#x2009;10), creatine ethyl ester (Cr-Ee, n&#x2009;=&#x2009;10), creatine hydrochloride (Cr-Hcl, n&#x2009;=&#x2009;10), and placebo (PL, n&#x2009;=&#x2009;10). All athletes engaged in a 4-week training intervention, three times a week (i.e. 12 sessions), and physical (countermovement vertical jump [CMVJ], 20-m sprint, and L-run) and physiological (Wingate anaerobic power and incremental exercise tests) performance were assessed both before and after the training period. RESULTS: All training groups improved physical and physiological performance following the 4-week intervention period (p&#x2009;<&#x2009;0.05). Additionally, the groups receiving the Cr supplement exhibited significantly greater changes (p&#x2009;=&#x2009;0.001) in physical performance, peak power output, and fatigue index compared to the PL group. However, no significant differences were found among the groups regarding mean power output and VO2max. Notably, the Ee and Hcl forms of Cr showed superior gains (p&#x2009;<&#x2009;0.05) in physical performance and peak power compared to the Mon form after the 4-week intervention. CONCLUSIONS: The results underscore the importance of Cr ingestion in enhancing adaptations for short-term physical performance tasks, highlighting the effectiveness of the Ee and Hcl forms in further improving the CMVJ, 20-m sprint, L-run, and peak power among soccer players during the short-term preparation phase.

CRISPR-Cas9&#x2011;based lipid nanocarriers for advanced therapy of urinary bladder cancer.

Bladder cancer (BCa) exhibits significant genetic and phenotypic variability. This variability suggests that various tumor subtypes could be influenced by several biomarkers and signaling pathways, which presents a problem for monotherapy strategies. Despite the initial effectiveness of traditional therapies, BCa's high rates of progression and recurrence, and the eventual development of drug resistance in many patients, continue to be major concerns. Because of the potential to transform the genetic modifications linked to the disease, genome editing using CRISPR/Cas9&#xa0;has become a transformative tool in medicine with noteworthy potential for BCa therapy. Although the CRISPR/Cas9 technology is incredibly effective at transforming the field of genome editing, its instability and cellular impermeability pose significant challenges to its delivery. To increase efficient delivery of CRISPR/Cas9, nanovectors may be investigated. Significant promise exists for improving the therapeutic potential of CRISPR-Cas9 technology and addressing complex cancer therapy difficulties because of the rapid development of nanotechnology-based delivery systems. Relevant articles were searched in Google Scholar, Scopus, and Web of Science covering studies published between 2007 and 2026. Along with the impact of lipid-based nanoparticles on their safe transport to cancer cells, this review emphasizes the significance of the CRISPR/Cas9 genome editing system in the treatment of BCa.

Probiotic supplementation increases fecal TLR4 agonists without improving disease activity in juvenile idiopathic arthritis: a randomized placebo-controlled trial.

Gut dysbiosis has been implicated in the pathogenesis of juvenile idiopathic arthritis (JIA), suggesting that microbiota-targeted interventions may influence immune signalling during early immune development. We conducted the PERMAJI multicentre randomized, double-blind, placebo-controlled trial to evaluate the effects of probiotic supplementation (VSL#3) on host-microbiota immune interactions and disease activity in children with oligoarticular or RF-negative polyarticular JIA. Participants were randomly assigned (1:1) to receive VSL#3 or placebo for 3 months in addition to standard therapy. Stool and serum samples collected at baseline and month 3 were used to assess gut microbiota composition, fecal innate immune agonists, intestinal permeability, and systemic cytokines. The primary clinical endpoint was the proportion achieving an ACR Pedi 30 response at 3 months. Forty-four children were enrolled between September 2017 and July 2022. Clinical responses did not differ between groups (ACR Pedi 30: 47% with VSL#3 vs 63% with placebo; p&#x2009;=&#x2009;0.33), and conservative worst-case assumptions for missing data suggested lower response rates with VSL#3 (36% vs 68%; p&#x2009;=&#x2009;0.03). Probiotic supplementation significantly increased fecal Toll-like receptor 4 (TLR4) agonist activity, whereas gut microbiota diversity, intestinal permeability, and systemic cytokine levels remained unchanged. These findings indicate that probiotic supplementation can modify microbial innate immune signalling without detectable changes in microbial community diversity and may increase exposure to pro-inflammatory microbial stimuli in early-life autoimmune disease. The results highlight the complexity of host-microbiota immune interactions and underscore the need for careful evaluation of microbiome-targeted therapies in paediatric autoimmune disorders.

Profiling tumor immune microenvironment of epithelial ovarian carcinoma.

BACKGROUND: Epithelial ovarian carcinoma (EOC) comprises five main histological subtypes: high-grade serous (HGSOC), low-grade serous (LGSOC), clear cell (CCOC), mucinous (MOC), and endometrioid (ENOC). Each histotype harbors specific genomic alterations and clinical outcome. Few studies systematically compared the tumor immune microenvironment across the five subtypes. METHODS: We performed 7-plex (CD45, CD8, CD68, CD163, FoxP3, CD20, and cytokeratin) sequential immunohistochemistry on a clinically annotated tissue microarray including 139 EOC representing the five subtypes and 26 borderline tumors (serous and mucinous). Digital pathology was used to quantify immune cell abundance, their spatial distribution (stroma vs tumor core), and correlation with survival. RESULTS: Immune cells were dominated by macrophages and more abundant in the stroma than tumor core across the five subtypes, consistent with immune excluded pattern. Compared to HGSOC, CCOC displayed the highest infiltration by CD45+ leukocytes and CD68+ macrophages, particularly M2-like CD163+ cells, suggesting a macrophage-rich, immunosuppressive phenotype. LGSOC exhibited the highest infiltration by intraepithelial FoxP3+ regulatory T cells. Comparison of borderline tumors with invasive carcinoma (LGOSC and MOC) revealed that malignant progression is accompanied by loss of CD8+ T cells, enrichment in regulatory T cells and increase of CD163+/CD68+ ratio, consistent with immune evasion during tumorigenesis. There was a trend toward better survival in HGSOC highly infiltrated by lymphocytes, either intraepithelial (CD8+ and FoxP3+) or stromal (FoxP3+ and CD20+). CONCLUSIONS: EOC is characterized by histotype-specific immune milieux defined by macrophage dominance, epithelial immune exclusion and dynamic immune remodeling during progression from borderline tumors to invasive carcinomas.

Immunogenicity and safety of inactivated TZ84- vs. HM175-based hepatitis A vaccines in pediatric populations: A systematic review and meta-analysis.

Individual studies indicate stronger and persistent long-term immunogenicity with TZ84-based than HM175-based hepatitis A vaccines. This systematic review and meta-analysis compared immunogenicity and safety of inactivated TZ84- and HM175-based hepatitis A vaccines in children and adolescents. Studies involving adults, immunocompromised populations, non-comparative designs, non-English publications, and studies with non-extractable outcomes were excluded. MEDLINE/PubMed, Google Scholar, other electronic databases, and grey literature were searched (September-October 2025). Risk of bias was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool, and meta-analyses were performed where appropriate. Seven publications arising from four randomized cohorts (total participants: 3,282) reporting seroconversion rates (SCRs), geometric mean concentrations (GMCs), long-term seroprotection, and adverse events (AEs) were identified. Pooled analyses demonstrated higher SCRs and GMCs with TZ84 than HM175-based vaccines following both one and two doses. SCRs at 1&#x2009;month [odds ratio (OR): 3.05; 95% confidence interval (CI): 1.88-4.96] and GMCs at 7&#x2009;months [standardized mean difference (SMD): 0.88; 95% CI: 0.18-1.58; p&#x2009;=&#x2009;.01] both favored TZ84-based vaccines. Long-term follow-up (up to 186&#x2009;months/15.5 y) showed higher reported anti-HAV antibody concentrations for TZ84-based vaccines. The AEs were comparable between vaccine types (RR: 0.95; 95% CI: 0.76-1.20; p&#x2009;=&#x2009;.69). Evidence was limited by the small number of unique randomized cohorts, geographic concentration in China, heterogeneity across studies, and reliance on surrogate immunogenicity outcomes. Overall, available evidence suggests that TZ84-based hepatitis A vaccines (HAPIBEV&#x2122;/HEALIVE&#xae;) are associated with higher reported antibody responses and greater reported antibody persistence than the HM175-based vaccine (HAVRIX&#xae;) in children and adolescents, with comparable safety profiles.Registration: PROSPERO CRD420251154480.

Molecular Pathogenesis, Global Epidemiological Trends, and Treatment Strategies for Pteropine Orthoreoviruses: A Narrative Review.

Pteropine orthoreoviruses are emerging bat-borne zoonotic viruses of the genus Orthoreovirus (family Reoviridae), increasingly recognized as causes of acute respiratory disease in humans. Originally grouped with the largely non-pathogenic mammalian orthoreoviruses, they have challenged that view through their association with severe influenza-like illness, evidence of human-to-human transmission, and a broad geographic range across the Old World. Maintained primarily in fruit bats of the family Pteropodidae, they are now linked to neurological as well as respiratory disease. This narrative review synthesizes current knowledge of their molecular pathogenesis, zoonotic ecology, and global epidemiology, integrating recent advances in phylogeography, reassortment-driven evolution, spillover dynamics, and translational biomedical applications within a unified One Health framework. Genomic diversity, reassortment potential, and the unique fusion-associated small transmembrane proteins together underpin viral adaptability and pathogenicity. Major gaps nonetheless remain in transmission dynamics, host adaptation, shedding ecology, and pandemic potential. Future priorities should include integrated genomic surveillance, improved diagnostic strategies, validated experimental models, and interdisciplinary One Health approaches to strengthen outbreak preparedness and prevention.

The complete chloroplast genome sequence and phylogenetic analysis of Amorphophallus gigas.

We sequenced the complete chloroplast genome of Amorphophallus gigas, a perennial monocotyledonous herb in Araceae, using HiFi technology. The genome is 173,034 bp in length with a GC content of 34.96%. It exhibits a typical quadripartite structure: a large single-copy (LSC) region of 95,283 bp, a small single-copy (SSC) region of 15,675 bp, and a pair of inverted repeat (IR) regions of 31,038 bp each. It encodes 130 genes (85 protein-coding, 37 tRNA, 8 rRNA). Phylogenetic analysis revealed that A. gigas is closely related to A. titanum, forming a distinct clade. This study provides valuable genomic resources for understanding the evolution of Amorphophallus and Araceae.

HiCPotts: An R/Bioconductor package to identify significant interactions in chromosome conformation capture data and model sources of bias.

MOTIVATION: Chromosome Conformation Capture methods, including Hi-C, micro-C or Capture-C, are used to map chromatin interactions genome-wide. Most of the existing computational methods do not account for sources of bias (such as DNA accessibility, GC content or TE content) in the data. RESULTS: We previously developed ZipHiC, a Bayesian method based on the hidden Markov random field (HMRF) model and the Approximate Bayesian Computation (ABC), that uses zero-inflated Poisson distribution to model the noise, signal and false signal of the data and showed that this approach was able to detect bias from DNA accessibility, GC content and TE content in both Hi-C and micro-C data. Here, we present HiCPotts, another Bayesian method based on the HMRF model and the ABC that uses a zero-inflated Negative Binomial distribution instead to model the noise and signal of the data. We systematically show that HiCPotts reduces false positives and increases recovery of true interactions compared to ZipHiC, but also compared to other methods such as FastHiC, Juicer and HiCExplorer. Most importantly, we provide an R/Bioconductor package that allows modelling the noise, signal and false signal using various distributions such as the zero-inflated Negative Binomial (ZINB) and the zero-inflated Poisson distribution (ZIP). AVAILABILITY AND IMPLEMENTATION: https://bioconductor.org/packages/HiCPotts/. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Mechanisms of Hexavalent Chromium-Induced Reproductive Toxicity: A Focus on the Ovary and Placenta.

Hexavalent Chromium (Cr(VI)) is a Group A carcinogen, mutagen, and teratogen. Cr(VI) has been used by more than 50 industries, and its contamination of drinking water is widespread across the United States (U.S.). Epidemiological data of women who lived in Willits, California, U.S., indicate that environmental exposure to Cr(VI) adversely affects pregnancy outcomes and the health of their immediate offspring, resulting in a low birth rate, pregnancy loss, and spontaneous abortion, and their children (F1 offspring) experienced birth defects. However, the molecular mechanisms behind Cr(VI)-induced reproductive and developmental toxicity are poorly understood. Cr(VI) enters cells through anion transporters and is rapidly reduced to Cr(III) by endogenous antioxidants within the cell. Cr(III) forms adducts with DNA, which can block DNA replication and transcription; abnormal repair can lead to DNA double-strand breaks, mutations, micronucleus formation, chromosomal abnormalities, and increased genomic instability. Cr(VI) induces oxidative stress via the Fenton reaction, generating free radicals, and depleting antioxidants, thereby promoting apoptosis via p53-dependent and independent pathways, resulting in follicular atresia and accelerated reproductive aging. Antioxidant supplementation with resveratrol, vitamin C, and edaravone mitigates Cr(VI) toxicity in the ovary. Cr(VI) disrupts meiosis in metaphase II oocytes by causing DNA strand breaks, altering F-actin dynamics, disturbing microtubules, and leading to chromosome missegregation. Gestational exposure to Cr(VI) also disrupts placental function through multiple mechanisms by targeting trophoblast lineages. The current review focuses on genotoxicity, oxidative stress, and other mechanisms by which Cr(VI) disrupts the female reproductive and endocrine systems, with particular emphasis on the ovary and placenta.
