The presence of meiotic bottlenecks directly influences the reproductive success of a plant species. The present study elaborates on chromosome number, male meiotic behavior, pollen viability, and seed set in six populations of Gloriosa superba, an important medicinal plant. The chromosome count recorded across all these populations was predominantly 2n=2x=22; however, anomalies in the form of laggards, inter-chromosomal connections, and precocious separation of bivalents were observed. In one of the populations, synizetic knot stage and inter-chromosomal connections were seen. At anaphase I, along with the normal segregation of 11 : 11 chromosomes, irregular segregations of 9 : 8, 11 : 9, 9 : 9, and 10 : 10 were also recorded. Both fruit and seed set percentages were very low for the species. We speculate that meiotic abnormalities are one of the reasons contributing to low reproductive output in Gloriosa superba.","PeriodicalId":10992,"journal":{"name":"Cytologia","volume":"90 3","pages":"179-186"},"PeriodicalIF":0.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.jstage.jst.go.jp/article/cytologia/90/3/90_D-24-00093/_pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early diagnosis of the disease is important in order to prevent the adverse outcome related to CKD. Many laboratories adopt creatinine-based e-GFR equations which yields imprecise results leading to misdiagnosis of CKD. Emerging studies indicated cystatin C as a better renal marker than creatinine. The aim of the study is to compare the efficacy of CKD epidemiology collaboration (CKD-EPI) creatinine e-GFR equations with (CKD EPI) cystatin-based e-GFR equations alone and in combination with creatinine for early detection of CKD. A cross-sectional study employing 473 patients was conducted. Three estimating GFR equations were calculated based on creatinine and cystatin C. Pearson Correlation study was done to assess the correlation of creatinine and cystatin C with their respective GFRs. A predictive model was developed, and ROC curve was constructed to compare efficacy, sensitivity and specificity of the creatinine and cystatin C based equations. Cystatin C exhibited better negative correlation with GFR than creatinine in correlation study performed with three commonly employed eGFR equations including CKD EPI Creatine cystatin C combined equation (2021), cys C alone and CKD EPI creatinine (2021) equations respectively[r=(-) 0.801 vs. r=(-)0.786 vs. r=(-)0.773]. Predictive model demonstrated highest efficiency, sensitivity and specificity for creatinine-cystatin C combined equation (88%, 81% and 93%) followed by cystatin C alone equation (73%,63% and 82%) and creatinine-based equation (61%, 56% and 66% respectively). The study showed better performance of cystatin C based equations for early detection of advance stages in chronic kidney disease as compared to creatinine-based e-GFR equation.","PeriodicalId":10992,"journal":{"name":"Cytologia","volume":"64 1","pages":"408-414"},"PeriodicalIF":0.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11239629/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88897532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
