For this reason, huge efforts are being invested in discovering suitable blood biomarkers that would allow early diagnosis and treatment. One of the possible promising candidates for this role are microRNA molecules (miRNAs). The aim of the study was to identify individual blood miRNAs that could be used as potential biomarkers for early diagnosis of lung cancer.\u0000\u0000\u0000METHODS\u0000This prospective study analyzed blood samples of 60 patients with early-stage lung cancer, and blood samples of 60 healthy individuals. All study patients with lung cancer had undergone radical pulmonary resection at the University Hospital Ostrava within the study period (2015-2017). Definitive diagnosis of lung cancer was confirmed by histopathology examination of the resected pulmonary specimen. We investigated relative expressions in selected 13 blood miRNAs; the examined miRNAs were miR-126, miR-155, miR-221, miR-21, miR-143, miR-145, miR-133a, let-7a, miR-146a, miR-31, miR-182, let-7g and miR-19b.\u0000\u0000\u0000RESULTS\u0000The outcome of this study showed that the levels of the majority of the tested circulating miRNA in lung cancer patients are significantly altered. The most significant serum miRNA biomarkers for the early detection of lung cancer are as follows: miR-143, let-7g, miR-126, let-7a, and miR-145 (miR-143 and miR-145 have oncogene functions, while miR-126, let-7g and let-7a have suppressor functions).\u0000\u0000\u0000CONCLUSIONS\u0000We have demonstrated the excellent diagnostic value of several miRNAs (miR-126, miR-143, miR-145, let-7a and let7g). These have an estimated sensitivity and specificity of 75-85% and 0.90-0.93 AUC. However, these individual miRNA biomarkers require further validation in larger prospective cohorts.","PeriodicalId":14912,"journal":{"name":"Journal of applied biomedicine","volume":"20 1 1","pages":"1-6"},"PeriodicalIF":1.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48332753","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 anti-bacterial activity, the minimum inhibitory concentration of the formulation against bacillary dysentery, causing microbes like Shigella flexneri (MTCC 1457), Escherichia coli (MTCC 1687), and Salmonella enterica (MTCC 98), was analysed by well-diffusion method and broth dilution method, respectively. The biofilm inhibition activity was determined on 96 well polystyrene plates and anti-quorum sensing activity by Chromobacterium violaceum CV026. The cytotoxicity was examined by acute oral toxicity. Excreta and organ bacterial load were analyzed by serial dilution method. The formulation efficacy was determined by analyzing the blood sample of rats. The antimicrobial efficacy of the developed formulation was calculated by measuring the zone of inhibition which was found to be 24 mm, 25 mm, and 25 mm, and the MIC values of 1.5 mg/ml, 1.5 mg/ml, and 2.0 mg/ml against S. flexneri, S. enterica, E. coli, respectively.

This study aimed to investigate the chemo-preventive effect of rosmarinic acid and evaluate its antitumor efficacy alone or in combination with Paclitaxel in breast cancer mice model. Ehrlich induced mice mammary solid tumor model was used in the study. Mice were treated with oral rosmarinic acid and intraperitoneal Paclitaxel. Inflammation, angiogenesis, and apoptosis were checked. Enzyme linked immunosorbent assay (ELISA), quantitative real time PCR, and immunohistochemical methods were performed. Rosmarinic acid used prior to tumor induction suppressed NF-κB, TNF-α, vascular endothelial growth factor (VEGF) serum levels, and VEGF receptors. It also triggered apoptosis by restoring the levels of P53, Bcl-2, Bax, and caspase-3. Furthermore, in Ehrlich solid tumor mice, rosmarinic acid, and/or Paclitaxel significantly suppressed tumor growth with an increase in apoptotic markers P53 and Caspase-3 levels, and suppressed the Bcl2/Bax ratio. Rosmarinic acid exerted chemo-preventive and therapeutic potential alone or in combination with Paclitaxel. Moreover, rosmarinic acid targets numerous signaling pathways associated with breast cancer.</p>","PeriodicalId":14912,"journal":{"name":"Journal of applied biomedicine","volume":"19 4","pages":"202-209"},"PeriodicalIF":1.3,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39814601","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}
