Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia)

The effect of triclosan on in vitro embryonic development in rat [Triklosanın in vitro embriyonik rat gelişimi üzerine etkisi]

Triclosan (TCS) is a broad spectrum antimicrobial agent showing its effect by deactivating the fatty acid synthesis of bacteria. The aim of this study was to investigate the effects of TCS on in vitro embryonic development in rats and to determine the levels of caspases 2, 7, 8, and 9 inducing cells to apoptosis through gene expression. According to the TCS dose added to the culture whole rat serum, 3 experimental groups and a control group were formed with each including 10 embryos. After 48 h culturing period, embryos were subjected to morphological scoring for developmental evaluation. The levels of caspases 2, 7, 8, and 9 were measured by performing gene expression on 40 embryos. Significant decreases were obtained in all parameters of morphological scoring in the experimental groups as the dose of TCS increased. While the caspase-2 level showed a significant decrease among the groups and was inversely proportional to the level of TCS, the caspase-9 level showed a significant increase among the groups and was directly proportional to the level of TCS. In conclusion, TCS was determined to cause apoptosis in the cells via the intrinsic pathway during pregnancy period and lead to embryonic growth retardation, which increased with increased dose of TCS. © 2020, Veteriner Fakultesi Dergisi.

Leptin levels in children with obstructive sleep apnea syndrome [Obstrüktif uyku apne sendromlu çocuklarda leptin seviyeleri]

Introduction: The aim of this study is to assess the effect of obstructive sleep apnea syndrome (OSAS) severity on leptin levels in children. Patients and Methods: Children with habitual snoring underwent overnight polysomnography. Fasting venous blood samples were obtained between 8 AM and 9 AM, following the night of the sleep study. Children with an apnea-hypopnea index of ? 5/h were included in the moderate-to-severe OSAS group while those with an apnea-hypopnea index of 0.05). Furthermore there were no differences in log serum leptin levels (p= 0.749). Log serum leptin levels correlated with the BMI z score in the whole study group (p= 0.001; r= 0.499) but they were not associated with apnea-hypopnea index, mean and lowest oxygen saturation during sleep. Conclusion: Serum leptin levels are affected by adiposity but not by OSAS severity among children with habitual snoring. © 2016, Ankara University. All rights reserved
