The extraction of oils from plant seeds is a crucial step in the preparation of these products, and the preservation of active and secondary metabolites is heavily dependent on the ambient temperature at which the extraction process is carried out. In this study, wheat germ oil (WGO) and tomato seed oil (TSO) were obtained from the Central Anatolia Region and the Aegean Region, respectively. Both oils were obtained via cold-pressing, and their infused forms (WGO-TSO) were also prepared. Cytotoxicity, wound healing, and antioxidant capacity tests were conducted on HaCaT (Human keratinocyte) and Vero (Monkey kidney fibroblast-like) cell lines to investigate the in vitro activities of these formulations. The results of the intracellular cytotoxicity analysis revealed that a common dose of 25 µg/mL was non-toxic for all samples, and this dose was subsequently used as the study dose. The hydrogen peroxide-based oxidant quenching studies and wound healing studies yielded positive results for all study groups, with the WGO/TSO group demonstrating statistically superior outcomes. In conclusion, the utilization of oils in infused forms may be more effective in combating oxidative stress and promoting wound healing as compared to the use of oils alone.","PeriodicalId":303081,"journal":{"name":"Frontiers in Life Sciences and Related Technologies","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123612352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces an algorithm for the detection of a distinct head, composed of undamaged DNA, and a tail, comprising damaged or fragmented DNA, in genotoxicity testing images, and provides information on the region properties of such images. The proposed approach combines a dot enhancement filter to distinguish and help in the detection of the head in each cell combined with a multilevel segmentation approach consisting of a watershed-geodesic active contour model that is capable to refine the tail estimation. The effectiveness of the suggested algorithm is quantitatively evaluated with annotation data provided by biologists, and its results are compared with those obtained from previous works. The proposed system exhibits comparable or superior performance to the existing systems while avoiding excessive computational cost.","PeriodicalId":303081,"journal":{"name":"Frontiers in Life Sciences and Related Technologies","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127732053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to add new information to the scientific literature, it is crucial to investigate the phenolic content and bioactivity of previously unstudied or unknown plant parts. Lonicera caucasica Pallas subsp. orientalis is an endemic species that grows in a few cities in Turkey. In this study, methanolic extraction of Lonicera caucasica leaves was performed, and the obtained fraction was analyzed by Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS) to determine the phenolic content of the extract. The amounts of 22 of the 56 identified phenolic compounds were determined. The three highest of these are chlorogenic acid (2.223 ± 0.065 mg g-1), quinic acid (2.163 ± 0.057 mg g-1) and syringic acid (1.192 ± 0,036 mg g-1). At the same time, the antioxidant activities of the extracts were examined and ABTS•+ and DPPH• (SC50, mg/mL) values were determined as 0.0135 ± 0.0001 and 0.0136 ± 0.0001, respectively. In addition, the obtained extract was tested against three gram-negative (P. aeruginosa, E. aerogenes and E. coli) and three gram-positive (E. fecalis, B. megaterium and S. pyogenes) bacteria and the results were recorded. The best antimicrobial activity was observed at 19.33 mm against P. aeruginosa at a dose of 3.9 mg mL-1. These results show that Lonicera caucasica leaves have rich phenolic content, high antioxidant activity, and a strong antimicrobial effect.","PeriodicalId":303081,"journal":{"name":"Frontiers in Life Sciences and Related Technologies","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122673204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bisphenol A (BPA), found in various consumer products, is known to deregulate multiple cellular signaling, but its effect on cancer initiation and development in breast tissue has not yet been fully elucidated. Therefore, the identification of hub drivers is necessary to understand the molecular mechanisms underlying BPA-related malignancy and may help determine novel diagnosis and treatment strategies. This study aimed to contribute to the understanding of the molecular mechanism of action of BPA on breast cancer formation using a bioinformatics analysis approach. A microarray dataset appropriate for study purposes was downloaded from the Gene Expression Omnibus (GEO) repository. After the screening of the differentially expressed genes (DEGs), enrichment analysis was performed. A protein-protein interaction (PPI) network was constructed and analyzed to identify the hub genes. mRNA expression and the prognostic impacts of the identified hub genes were verified using GEPIA2 and KM-plotter tools. Finally, correlations between hub genes and immune infiltration levels were validated. According to PPI network results, CCNA2 and CCNB1 were identified as critical hub genes. Validation analyses clearly indicated that the identified genes are extremely critical in the development and progression of BPA-associated breast cancer. Findings from this study revealed that CCNA2 and CCNB1, two cell cycle signaling-related hub genes that are overexpressed as a consequence of BPA exposure, are strongly associated with poor prognosis in patients with breast cancer.","PeriodicalId":303081,"journal":{"name":"Frontiers in Life Sciences and Related Technologies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121946367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
