With this in mind, the ultimate goal of this investigation is to fabricate sophisticated scaffolds using jellyfish collagen (JC) and aqueous Salvadora persica (Miswak) extracts. Rhizostoma pulmo species JC was isolated and characterized in depth. Miswak was extracted using two different methods. The extraction yield was calculated to be 14.2 ± 0.9 % and 17.1 ± 0.4 % for the Method I and II, respectively. gas chromatography-mass spectroscopy (GC-MS) results revealed the extract to be composed of 1,8-cineole (49.3 %), benzyl nitrile (36.2 %), benzyl isothiocyanate (5.9 %), limonene (2.4 %), eugenol (0.8 %) and palmitic acid (0.3 %). Total phenolic content and antioxidant capacities of the extracts were also determined by spectrophotometrically. Human periodontal ligament fibroblast cells were isolated and expanded. Cell viability on JC and miswak extract-laden JC scaffolds was determined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay. Microarchitectures of the JC, 0.05 and 0.1% miswak extract-laden JC scaffolds and also cellular behaviors on these surfaces were evaluated by scanning electron microscopy (SEM) analysis. This study suggests that miswak extract-laden JC scaffolds would present new opportunities for periodontal tissue engineering.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42957076","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}

The obtained compounds were investigated for antioxidant properties by using different methods such as a DPPH radical scavenging assay, ABTS radical decolarization, cupric reducing antioxidant capacity (CUPRAC) and metal chelating methods. The cholinesterase inhibition activities (acetylcholinesterase and butyrylcholinesterase) of synthesized compounds were also tested. In general, compounds showed weak antioxidant activity, except compounds 4d (IC 50 =114.89 for DPPH activity), 4i (IC 50 =25.31 for ABTS activity), 4a (IC 50 = 86.33 for metal chelating activity), and 4k (absorbance value 1.229 µM for CUPRAC).

Fast and reliable analysis of the alcoholic beverages, especially in terms of methanol concentration, has vital importance primarily due to the cases of death arose from metabolic acidosis after consumption of illicit alcoholic beverages with high concentration of methanol produced in clandestine laboratories. 96 Turkish Raki samples, 8 beer samples, 1 wine sample, 101 other strong drink samples, totaling to 206 samples, and 2 industrial ethanol samples were thoroughly investigated. An HS-GC-MS system was utilized for qualitative analysis of the higher alcohols and for scanning any volatile compound, whereas the determination of ethanol and methanol concentrations HS-GC-FID system was performed. So, after all results were investigated in detail, mentioning the key points for evaluations, it was clearly described whether the drinks comply with criteria set by Turkish Food Codex Communique on Distilled Alcoholic Beverages. 89 of 96 Raki samples and 90 of 101 strong alcoholic beverages were not definitely compliant with the Communique since they contained either high concentration levels of methanol or tert-butanol, which is a denaturant.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48401252","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}
