Since it is not yet possible to distinguish spermatogonial stem cells of European eel ( Anguilla anguilla ) using specific molecular markers, we isolated spermatogonial cells from immature European eels to find these potential markers. We attempted this by studying three candidate genes: vasa , nanos2 , and dnd1 . Two vasa ( vasa1 and vasa2 ) genes, nanos2 , and dnd1 were identified, characterized, and studied in the muscle, testis, and isolated spermatogonia. Our results showed that vasa1 and vasa2 had the highest levels of expression when measured by qPCR. In situ hybridization and immunochemistry assays showed that the four genes were localized explicitly in type A spermatogonia. However, vasa1 and vasa2 exhibited stronger signals in the immature testicular tissue than the other two potential markers. According to this, vasa1 and vasa2 were found to be the most effective markers for spermatogonial cells in the European eel.}, year = {2024}, eissn = {1573-5168}, orcid-numbers = {Blanes-García, Marta/0000-0002-0858-0076; Marinović, Zoran/0000-0003-3980-8325; Herranz-Jusdado, Juan Germán/0000-0001-8773-4637; Pérez, Luz/0000-0002-6678-7446; Horváth, Ákos/0000-0001-9760-2478; Pšenička, Martin/0000-0002-3808-7856; Asturiano, Juan F./0000-0002-6441-5294; Morini, Marina/0000-0003-3313-3419} } @article{MTMT:34789080, title = {Tudományos Diákköri Konferencián vettek részt a MATE Akvakultúra és Környezetbiztonsági Intézet hallgatói}, url = {https://m2.mtmt.hu/api/publication/34789080}, author = {Bokor, Zoltán and Urbányi, Béla}, journal-iso = {HALÁSZAT}, journal = {HALÁSZAT}, volume = {117}, unique-id = {34789080}, issn = {0133-1922}, year = {2024}, pages = {33-35} } @article{MTMT:34779466, title = {Ausztráliai tapasztalatok}, url = {https://m2.mtmt.hu/api/publication/34779466}, author = {Horváth, Ákos}, journal-iso = {HALÁSZAT}, journal = {HALÁSZAT}, volume = {117}, unique-id = {34779466}, issn = {0133-1922}, year = {2024}, pages = {14-15}, orcid-numbers = {Horváth, Ákos/0000-0001-9760-2478} } @CONFERENCE{MTMT:34778513, title = {Growth performance of different airbreathing (Clariidae) catfish lines}, url = {https://m2.mtmt.hu/api/publication/34778513}, author = {Kovács, Balázs and Réka, Enikő Balogh and Balázs, Csorbai and Julianna, Kobolák and Dániel, Péter and István, Lehoczky and Gyula, Kovács and Bogár, Katalin and Gyöngyvér, Fazekas and Géczi, Aliz and Milán, Varjú and Gábor, Szilágyi and Béla, Urbányi}, booktitle = {59th Croatian & 19th International Symposium on Agriculture : Book of Abstracts}, unique-id = {34778513}, year = {2024}, pages = {156}, orcid-numbers = {Kovács, Balázs/0000-0003-1753-5098} } @article{MTMT:34777486, title = {Rainbow trout ( Oncorhynchus mykiss , Walbaum 1792) adenocarcinoma investigation with various diagnostic imaging techniques}, url = {https://m2.mtmt.hu/api/publication/34777486}, author = {Hoitsy, Márton György and Hoitsy, György and Gál, János and Ziszisz, Árisz and Tóth, Tamás and Sós, Endre and Sós‐Koroknai, Viktória and Jakab, Csaba and Petneházy, Örs and Donkó, Tamás and Molnár, Tamás Gergely and Marosán, Miklós}, doi = {10.1111/jfd.13951}, journal-iso = {J FISH DIS}, journal = {JOURNAL OF FISH DISEASES}, unique-id = {34777486}, issn = {0140-7775}, abstract = {Diagnostic imaging techniques provide a new aspect of the ante‐mortem and post‐mortem diagnostics in fish medicine. Ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) can provide more information about the internal organs and pathognomic lesions. The authors used diagnostic imaging techniques to evaluate and describe the neoplastic malformation in a 3‐year‐old female rainbow trout ( Oncorhynchus mykiss ). The fish was examined with Siemens Somatom Definition AS + CT scanner and Siemens Biograph mMR scanner. The animal was lethargic and showed anorectic signs and muscular dystrophy. During the post‐mortem investigation, histopathology and immunohistochemistry were also performed allowing us to identify the neoplasms. The results showed a large soft tissue mass in the first mid‐intestine segment, which proved to be an adenocarcinoma. This subsequently led to digestion problems and absorption disorders. Immunohistochemically, neoplastic cells of carcinoma revealed E‐cadherin and pancytokeratin positivity.

Its main inflow, the Zala River, enters the lake through an artificially constructed wetland, the Kis-Balaton Water Protection System and its catchment area (KB), which helps preserve the water quality of the lake. From these two areas, 15 samples were taken with an in situ filtration sampling method. After preparation, the samples were analyzed automatically by FT-IR microscopy. All samples, from both areas, contained MPs; the dominant microplastic (MP) shape was the fragment, while the most frequently polymer types were polyethylene, polypropylene and alkyd. Small MPs were dominant in both areas; around 90% of the MPs were smaller than 500 μm. On average, LB contained more MPs (21.0 ± 12.5 MPs/m3) compared to the KB, which presented an average concentration of MPs of 7.8 ± 5.9 MPs/m3. In the examined areas, two potential MP sources were determined, i.e., treated wastewater and road traffic.

A. aquaticus were introduced into experimental setups of dead eggs, viable eggs and hatched larvae of zebrafish ( Danio rerio ), a commonly used model organism. The amount of A. aquaticus and the duration of their exposure to the eggs significantly affected the proportion of consumed dead eggs in each experimental cycle. A. aquaticus belongs to the group of aquatic detritivores, and no predatory behavior was observed during the experiments. These crustaceans could distinguish between the dead eggs and those containing living embryos. Furthermore, zebrafish larvae remained unharmed by A. aquaticus , even in the absence of alternative food source. These findings underscore the potential sanitary role of these crustaceans in natural waters and offer new perspectives on their possible use as biological control organisms in aquaculture hatcheries. Additionally, our results suggest a potential application of A. aquaticus in combating pathogens by reducing the growth substrates for bacteria and fungi.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Quyen, Nguyen Ngoc/0000-0001-5741-590X; Griffitts, Jeffrey/0000-0002-1518-0054} }
