Surgical trauma causes many pathophysiological processes which include inflammation, oxidation, coagulation, fibrinolysis, cell proliferation, and apoptosis. After intra-abdominal operations, the adhesion tissue may occur on the peritoneal surface due to low fibrinolytic activity. This may result in permanent excessive adhesion tissue bands instead of properly formed fibrin structures. Therefore, anticoagulant, thrombolytic, and fibrinolytic activities have a key role in preventing peritoneal adhesion. Indeed, several studies have been conducted to find out new and effective agents against intra-abdominal adhesion. Thus, revealing the causes, development processes, and investigation techniques are highly important for designing and conducting such scientific studies. In this context, this study aims to summarize the pathophysiological processes of above-mentioned activities and to emphasize their importance in the peritoneal adhesion model as well as to explain the evaluation methods, particularly in terms of the investigation of natural products.","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136183560","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 results showed that the mutation frequencies approached the negative control values by inhibiting the formation of chemical agent-induced mutant clones in all doses in the experimental groups in which plant extracts were applied at doses of 1.25, 2.5 ve 5 mg/mL, while the mutation frequency increased only in the groups that applied cisplatin and valproic acid.

They may also be referred to as journal rankings, journal relevance, or journal impact. Journal metrics allow academics and researchers to compare scholarly publications. The most prestigious ones are the Journal Impact Factor (JIF) based on Web of Science data, and CiteScore and SCImago Journal Rank (SJR) based on Scopus data. As we all know, the availability of these metrics for a journal is associated with its indexing in these bibliographic databases, such as the Web of Science Core Collection or Scopus, and is a proxy to determining the quality of the journal.  The number of open access journals is growing rapidly. According to a report by the University of Regensburg Library, there were more than 60,000 open access journals worldwide in 2018 (EBZ 2018). While open access has brought many benefits to academic publishing, it has also introduced us to many low-quality (Non-indexed) journals, as well as predatory journals and publishers. Thousands of journals therefore compete for manuscripts from researchers/authors. It is clear how difficult it is for new and low-quality journals to receive manuscripts in this competitive environment. Naturally, authors do not want to submit their research to journals that are not indexed or have no metrics. Recently, in some countries, publishing in predatory journals has even become a barrier to academic promotion (Koçak 2012).","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136183179","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}

While there have been numerous studies on pollen transportation by birds in Europe, there is a lack of research concerning the pollen grains transported by bird species in Turkey. In this context, we explored the role of Sylviidae species in pollination and identified the plant species whose pollen is transported by these birds. The temporary ringing station located at İstanbul University-Cerrahpaşa Avcılar Campus was selected as the study area and a total of 35 feather samples were collected from individuals of Sylvia atricapilla (Linnaeus), S. borin (Boddaert), Curruca communis (Latham), C. cantillans (Pallas), C. curruca (Linnaeus) and C. melanocephala (Gmelin) captured at station. Based on the analysis of pollen found on the feather samples, it was determined that the pollen found in 18 feather samples of Curruca curruca and Sylvia atricapilla provided pollen belonging to Pinus (Pine), Aesculus (Horse chestnut), Prunus (Plum), Spiraea (Spiraea), Quercus (Oak), Fraxinus (Ash) and Melia (Bead tree). The most commonly determined pollen on C. curruca were of Prunus (63.5%), while the least common were of Aesculus (0.9%). The most commonly determined pollen on S. atricapilla were of Melia (48.1%), while the least common were of Crocus (0.2%). The presence of pollen among the food sources of Sylviidae species during spring, the synchronization between the arrival time of birds in the study area during migration and the pollination period of the determined plant taxa, and the prevalence of these taxa in the study area suggest that S. atricapilla and C. curruca may be contributing to pollination.","PeriodicalId":23163,"journal":{"name":"Trakya University Journal of Natural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184210","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}
