Conivaptan and amphotericin B were obtained in docking analysis with AutoDock Vina and Sybyl-X, respectively. Docking analysis with Glide SP and Glide XP resulted in fludarabine and panobinostat, respectively. Molecular dynamics simulations were performed for a period of 120 ns to check the stability of these four drugs.\u0000Result and Discussion: The reliability of the results obtained using four different molecular docking programs on the SARS-CoV-2 papain-like protease of 1300 drug molecules was checked by reinserting the co-crystal ligand. Protein-ligand interactions between fludarabine, conivaptan, amphotericin-B, panobinostat, and PLpro were given. In the molecular dynamics study, RMSD, RMSF, Rg, and SASA analyses were performed for four systems. It was observed that RMSD remained constant for all 120 ns for all four systems except for amphotericin B, which deviated slightly towards the end of 120 ns. No significant fluctuation was noticed in the RMSF graphics for all four systems.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43449432","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 typical electrochemical behavior of OTB was identified as being dependent on the type of working electrode and pH. This research aims to provide a brand-new electroanalytical technique for measuring OTB in buffer solutions.\u0000Material and Method: All experiments employed the typical three-electrode cell of 10 ml capacity in conjunction with a platinum wire counter electrode, a BDDE and GCE working electrode, and an Ag/AgCl reference electrode. NOVA 1.8 software and an AUTOLAB 204 potentiostat/galvanostat were used for electrochemical measurements.\u0000Result and Discussion: The electrochemical behavior of OTB, which belongs to a class of drugs called 'antispasmodics' (spasm and cramps reliever), primarily used to treat irritable bowel syndrome (IBS), and other gastrointestinal conditions characterized by motility problems, painful bowel spasms and distension (swelling and bloating in the belly area), was examined in 0.1 M H2SO4 at BDDE and GCE. The electrooxidation mechanism was also investigated by conducting CV investigations at various pH levels throughout a broad pH range (pH 0.3-12.0). Understanding the mechanism was aided by scan rate investigations, which revealed that diffusion was controlled for both electrodes. The proposed technique was successfully used to determine OTB under optimal conditions.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46034928","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}

According to the Food and Agriculture Organization (FAO), these substances contaminate about 25% of all food in the world. Mycotoxins are responsible for many different disorders affecting the gastrointestinal, urogenital, vascular, renal, and nervous systems, as well as cancers. Key strategies for preventing and controlling exposure to mycotoxins include controlling toxin formation, implementing surveillance and monitoring programs to prevent human exposure, detoxifying the mycotoxins through biological, chemical, and physical means, and promoting dietary diversification. Although exposure cannot be avoided entirely, implementing monitoring programs is crucial to minimize it. In general, prevention of exposure to mycotoxins should receive greater emphasis. This study aims to provide information about mycotoxins and raise awareness about mycotoxin exposure.\u0000Material and Method: This cross-sectional survey study was conducted with voluntary participants in Turkey between January 25, 2023-July 25, 2023, via electronic questionnaire. The questionnaire included socio-demographic data, income status, general dietary habits, frequency of consumption of mycotoxin-rich foods, knowledge about mycotoxins, and implementation of measures to prevent mycotoxin exposure.\u0000Result and Discussion: A total of 796 participants (52.6% female, 46.7% male, and 0.6% other) were included in the study. This study concludes that the participants considered both the price and quality of food to be important factors. The study indicates that a high percentage of participants are unaware of the concept of mycotoxin and the associated health risk. A statistically significant change was found between whether the participants were knowledgeable about nutrition and whether they knew the concept of mycotoxin (p<0.05). There was a statistically significant difference in participants' knowledge of healthy nutrition and knowledge of the health hazards of mycotoxins. (p<0.05). The results indicate a requirement for comprehensive management against mycotoxins and mycotoxin exposure, which can cause several health problems in humans.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47879105","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}
