Insulin-like growth factor II mRNA-binding protein 3 (IMP3) expression was recently reported to be associated with chemotherapy resistance and poor prognosis in TNBC.Methods: We evaluated IMP3 expression in 40 female TNBC patients to assess its association with NAC sensitivity and outcome.Results: Among the cohort, 11 patients (27.5%) had IMP3-positive TNBC, which was associated with a higher Ki-67 labeling index (p = 0.119), indicating greater malignancy. However, IMP3 positivity showed no significant correlation with NAC resistance or differences in disease-free survival (DFS) as compared with IMP3-negative patients.Conclusions: Patients receiving effective immunotherapy or high-dose chemotherapy achieved pCR regardless of IMP3 status, which suggests that the NAC regimen is more important than IMP3 status for pCR. Even in IMP3-positive TNBC, NAC may improve prognosis by achieving pCR. Thus, while IMP3 might predict poor prognosis, it may not serve as a definitive marker in the context of NAC. Because IMP3 is involved in cancer stem cell (CSC) function, further research is necessary to understand its complex role in CSCs and TNBC.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":"92 1","pages":"44-51"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143588380","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}

We examined weather data, including monthly average precipitation and humidity, with respect to the number of patients with V/D.Results: Among 706 patients with V/D, 481 presented with vertigo and 225 with dizziness. The mean age was 59±18 years and 66% were female. Regarding triage level, emergent (level 2) and urgent (level 3) cases accounted for 86% of cases and were more frequent in June-September (p=0.012). Regarding seasonality, 158 (22%), 195 (28%), 183 (26%), and 170 (24%) patients presented in spring, summer, autumn, and winter, respectively (p=0.744).

The relationship between LA dilatation and MA remodeling, and the mechanism of MR associated with MA remodeling, are unclear and were investigated in this study.Methods: This single-center, cross-sectional retrospective study prospectively enrolled 97 consecutive patients with atrial fibrillation (AF) referred for three-dimensional transesophageal echocardiography. Mitral valve echocardiographic data of 18 AF patients with moderate or severe MR (MR group) and 79 with mild or less severe MR (non-MR group) were analyzed.Results: The LA volume index was larger and tenting height was lower in the MR group than in the non-MR group (63.9±17.9 mL/m2 vs. 43.6±13.9 mL/m2; p<0.001; 3.9 mm vs. 4.9 mm; p = 0.041). Anteroposterior (AP) diameter, annulus area, and sphericity index (AP diameter/anterolateral-posteromedial diameter) of MA were larger in the MR group than in the non-MR group (30.1 mm vs. 26.4 mm; p<0.001; 8.8 cm2 vs. 7.4 cm2; p = 0.002; 80.1% vs. 74.5%; p<0.001, respectively). Linear regression analysis indicated that AP diameter was moderately correlated with LA volume index (R = 0.535, p<0.001). The area under the receiver operating characteristics curve of the AP diameter for the association with significant MR was significantly larger than that for the annulus area (0.8003 vs. 0.7180; p = 0.003). Multivariable analysis revealed that AP diameter (p = 0.006) and sphericity index (p = 0.041) were independently associated with significant MR, but annulus area was not (p = 0.083).Conclusions: LA dilatation correlated with MA remodeling, primarily via enlargement of AP diameter. Circular change with AP diameter enlargement in MA may be a key mechanism of MR associated with MA remodeling.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":"92 2","pages":"145-153"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121567","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}

Emerging evidence suggests that oligodendrocytes (OLs) and oligodendrocyte precursor cells (OPCs) play pivotal roles in these pathologies via mechanisms involving neuroinflammation, energy metabolism, and hormonal modulation, resulting in distinct functional outcomes. Specifically, female OPCs display higher proliferative and migratory capacities, whereas male OPCs are more prone to differentiation and myelination, thus contributing to robust myelin integrity. Dysregulation of these cells disrupts myelination and exacerbates disease progression. Addressing sex-specific gene expression in OPCs and OLs is therefore considered crucial for the development of targeted therapeutic strategies. This review highlights the significance of sex differences in the proliferation and differentiation of OPCs, as well as gene expression changes in OPCs and OLs, and emphasizes their contribution to the pathophysiology of neuropsychiatric disorders. Improved understanding of these differences is vital for advancing personalized sex-specific treatments and improving the clinical outcomes of neuropsychiatric disorders.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":"92 3","pages":"226-233"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144555936","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}
