Although several studies suggest that walkable and activity-supportive environments promote better health, other findings indicate that certain environmental features, including food establishments, might increase obesity and diabetes mellitus (DM). How different environmental elements affect both physical activity and DM incidence remains unclear. We investigated associations of NBE with physical activity and DM incidence. This study included 87,154 individuals (33,884 males and 53,270 females) with national health insurance in Gunma Prefecture, Japan, who underwent the Specific Health Checkup in FY2011. These individuals were followed up for 7 years (until FY2018). The odds ratio (OR) for engaging in physical activity was significantly higher in neighborhoods with convenience stores [OR: 1.07, 95% confidence interval (CI): 1.03, 1.10] or parks (OR: 1.09, 95% CI: 1.06, 1.13) but significantly lower in neighborhoods with train stations (OR: 0.96, 95% CI: 0.92, 0.99). The proportion of individuals engaging in physical activity tended to increase when the number of NBE increased. DM incidence risk was significantly lower in neighborhoods with parks [hazard ratio (HR): 0.90, 95% CI: 0.83, 0.98] and higher in neighborhoods with convenience stores (HR: 1.09, 95% CI: 1.01, 1.18). These results suggest that having parks in neighborhoods may contribute to reducing DM risk, whereas convenience stores may increase it.

Long non-coding RNAs (lncRNAs) play critical roles in immune regulation and inflammatory responses, but their specific mechanisms in AR remain unclear. This study aimed to investigate the expression profile, clinical relevance, and functional mechanism of lncRNA TTC28-AS1 in AR, focusing on its regulation of nasal epithelial inflammation via miR-767-5p. RT-qPCR was used to measure lnc TTC28-AS1, miR-767-5p, and inflammatory cytokines (GM-CSF, eotaxin-1) expression in nasal mucosa tissues from AR patients and healthy controls. Receiver operating characteristic (ROC) curve analysis evaluated the diagnostic efficacy of lnc TTC28-AS1, while Pearson correlation assessed its association with clinical symptom scores. The targeting relationship between lnc TTC28-AS1 and miR-767-5p was validated by dual-luciferase reporter assay. In an interleukin (IL)-13-induced human nasal epithelial cell (HNEC) model, the effects of the lnc TTC28-AS1/miR-767-5p axis on cell proliferation were analyzed via CCK-8 assay. Apoptosis was examined by flow cytometry analysis. Lnc TTC28-AS1 was significantly upregulated in AR patients and positively correlated with total nasal symptom score (TNSS). Its overexpression was an independent AR risk factor. Lnc TTC28-AS1 directly suppressed miR-767-5p, exacerbating inflammation and apoptosis in HNECs. Silencing lnc TTC28-AS1 reduced IL-13-induced GM-CSF/eotaxin-1 expression and apoptosis promoting proliferation, effects reversed by miR-767-5p inhibition. In conclusion, Lnc TTC28-AS1 modulates inflammatory responses and functional status of nasal epithelial cells by targeting miR-767-5p, suggesting its potential as a novel diagnostic biomarker and therapeutic target for AR.</p>","PeriodicalId":23187,"journal":{"name":"Tohoku Journal of Experimental Medicine","volume":" ","pages":"499-506"},"PeriodicalIF":1.5,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145726247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included 200 individuals, and transcranial Doppler (TCD), MRI, and clinical data were collected. Patients were divided into low-burden (0-1 points) and high-burden (2-4 points) groups according to the total MRI burden score. Univariate and multivariate logistic regression analyses and Spearman rank correlation analysis were used to assess the association between MCA PI and total MRI burden. The predictive value of MCA PI for high MRI burden in elderly patients with CSVD was assessed using receiver operating characteristic (ROC) curves. Multivariate logistic regression showed that, after adjustment for other confounding factors, MCA PI remained associated with total MRI burden (P < 0.001). Spearman rank correlation analysis showed that MCA PI was strongly correlated with the total MRI burden score in elderly patients with CSVD (rs = 0.583, P < 0.001). A cut-off value of 1.11 for MCA PI was optimal for predicting high MRI burden in elderly patients with CSVD, with an area under the curve (AUC) of 0.923 (P < 0.001, 95% CI: 0.851-0.927), a sensitivity of 0.864, and a specificity of 0.78.

Human prostate cell lines WPMY-1 and BPH-1 underwent transfection and treatment of endoplasmic reticulum (ER) stress inhibitors 4-phenylbutyric acid (4-PBA) or tauroursodeoxycholic acid (TUDCA), after which the cell viability, lactate dehydrogenase (LDH) activity (cytotoxicity) and pyroptosis were determined through cell counting kit-8 assay, specific kits, and flow cytometry, respectively.

Heat shock protein family A (Hsp70) member 1B (HSPA1B) was highly expressed in BPH.

These advances have highlighted several fundamental principles, including patient enrichment, intervention during appropriate therapeutic windows, biomarker-guided drug development, and innovative clinical trial design. At the biological level, human genetics and molecular neuropathology have revealed that genetically diverse forms of ALS converge on a limited number of shared pathogenic pathways. In particular, TDP-43 proteinopathy has emerged as the central molecular hallmark of ALS, linking protein aggregation, RNA dysregulation, and neuronal dysfunction. The discovery of TDP-43-dependent cryptic splicing has transformed RNA dysregulation into a therapeutically actionable target and accelerated the development of RNA-targeted therapeutics and mechanism-based biomarkers. In parallel, patient-derived induced pluripotent stem cell (iPSC) models, multi-omics technologies, and computational approaches have fundamentally altered therapeutic discovery and target validation. Furthermore, neurofilament biomarkers, adaptive platform trials, and digital technologies are reshaping clinical evaluation and accelerating therapeutic development.
