The objective of the current study was to assess this potential risk.Materials and methods: The potential risk of PIO-induced urinary bladder carcinoma was assessed in the current study by examining urinary bladder of rats for urothelial cytokeratin (CK) expression and proliferative activity by Ki67 immunostaining.Results: Histological examination revealed dysplastic urothelial changes in PIO per se and diabetes mellitus + PIO (diabetic rats receiving PIO). In addition, a significantly (P < 0.05) decreased CK7 and CK8 expression together with a significantly increased CK20 as well as Ki67 expression was detected in the urothelial cells of groups administrated PIO, contrary to those which did not.Conclusion: The manifestations of urothelial dysplasia evidenced by histological examination as well as by the aberrant expression in CK and Ki67 after PIO administration add supporting evidence at cellular and experimental level to the previous clinical suspicions.","PeriodicalId":16340,"journal":{"name":"Journal of Microscopy and Ultrastructure","volume":"11 1","pages":"34-40"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/62/c5/JMAU-11-34.PMC10153741.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9415554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite considerable success in reducing DH, unfortunately, most of the present methods can provide only temporary and unpredictable desensitization. Therefore, new treatment methods that are effective for long periods and at the same time do not have the complications are needed. Recently, two new desensitizing agents BioMin F and Propolis have been introduced for the treatment of DH.Aim: The aim of the study was to compare and evaluate the efficacy of BioMin F and Propolis containing toothpastes on dentinal tubule occlusion with and without the use of an adjunct 810 nm Diode Laser.Materials and methods: Forty-five freshly extracted teeth were taken out of which thirty were sectioned into halves and divided into four test groups BioMin F, Propolis, BioMin F + Laser, and Propolis + Laser and control group. All the specimens were treated twice a day for 7 days and then evaluated under scanning electron microscope for partial and complete dentinal tubule occlusion.Results: A significantly higher number of completely occluded tubules were seen in BioMin F + laser group followed by Propolis + laser, Biomin F, and Propolis.Conclusion: Combination approach of desensitizing agent and laser provided a better result than the desensitizing agent alone and when compared individually Biomin F was more effective desensitizer as compared to Propolis.","PeriodicalId":16340,"journal":{"name":"Journal of Microscopy and Ultrastructure","volume":"11 1","pages":"41-46"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/cb/27/JMAU-11-41.PMC10153734.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9784178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reticular and erosive are the most frequently encountered. Its proliferative capacity can give some information regarding its progression. We adopted the argyrophilic nucleolar organizer regions (AgNORs) method because of its simplicity to use and dependable results. We evaluated AgNORs in basal, suprabasal, and squamous cell layers. We also compared these three layers within two variants, reticular, and erosive.Materials and methods: Thirty clinically diagnosed patients of OLP were included in the study. Reticular and erosive variants were included in our study. This was followed by hematoxylin and eosin staining and later by the AgNOR method. The mean number of AgNORs per nucleus was calculated.Results: Thirteen males and 17 females were the gender distribution. Twenty-three (76.67%) had reticular pattern and seven (23.33%) had erosive pattern. The basal cell layer had the highest mean AgNOR compared to suprabasal and squamous layers. Even among, erosive and reticular variants, the former had higher mean AgNOR counts.Discussion: Our results suggest that the inflammatory infiltrate close to the epithelial cells can alter the proliferation index for the pattern of protein synthesis of these cells. Moreover, the high proliferative index in OLP can be related to a specific immunologic response.Conclusion: We conclude that AgNOR can be used as a proliferative marker in earlier lesions to detect the severity.","PeriodicalId":16340,"journal":{"name":"Journal of Microscopy and Ultrastructure","volume":"11 1","pages":"12-16"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/8d/b1/JMAU-11-12.PMC10153732.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9416899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
