Changes in short chain FA (SCFA) composition are associated with gut microbiota modifications. However, the effect of bacteria-driven changes on the detailed FA spectrum has not been explored yet. We investigated the effect of antibiotics (ABx) and/or probiotics, in four treatment groups on rat stool FA composition. Principal component analysis indicated that the chromatogram profiles of the treatment groups differ, which was also observed at different time points. Linear mixed effects models showed that in the parameters compared (sampling times, treatments. and their interactions), both the weight percentage and the concentration of FAs were affected by ABx and probiotic administration. This study found that the gut microbiome defines trans and branched saturated FAs, most saturated FAs, and unsaturated FAs with less carbon atoms. These results are among the first ones to demonstrate the restoring effects of a probiotic mixture on a substantial part of the altered total FA spectrum, and also revealed a previously unknown relationship between gut bacteria and a larger group of FAs. These findings suggest that intestinal bacteria produce not only SCFAs but also other FAs that may affect the host’s physiological processes.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Marosvölgyi, Tamás/0000-0002-4244-5513; Mintál, Kitti/0009-0003-4739-2902; Borbásné Farkas, Kornélia/0000-0002-5349-6527; Sipos, Zoltán/0000-0001-7845-8116; Makszin, Lilla/0000-0002-9764-4763; Hormay, Edina/0009-0004-0598-5061} } @CONFERENCE{MTMT:34735416, title = {Different aspects of the taste reactivity test to interpret gustatory responses elicited organismic changes.}, url = {https://m2.mtmt.hu/api/publication/34735416}, author = {Hormay, Edina and Mintál, Kitti and László, Bettina Réka and Szabó, István and Tóth, Attila and László, Kristóf and Győrfi, Nina Rubina and Lénárd, László and Karádi, Zoltán György}, booktitle = {7th Hungarian Neuroscience Doctoral Conference for Undergraduate Students, Graduate Students and Junior Post-Docs (HUNDOC) Booklet}, unique-id = {34735416}, year = {2024}, pages = {48}, orcid-numbers = {Hormay, Edina/0009-0004-0598-5061; Mintál, Kitti/0009-0003-4739-2902} } @CONFERENCE{MTMT:34735333, title = {Long term saccharose consumption associated activity of limbic forebrain glucose-monitoring neurons: A pilot study in the rat.}, url = {https://m2.mtmt.hu/api/publication/34735333}, author = {Hormay, Edina and Mintál, Kitti and László, Bettina Réka and Szabó, István and Tóth, Attila and László, Kristóf and Győrfi, Nina Rubina and Lénárd, László and Karádi, Zoltán György}, booktitle = {International Neuroscience Conference, Pécs 2024}, unique-id = {34735333}, year = {2024}, pages = {129}, orcid-numbers = {Hormay, Edina/0009-0004-0598-5061; Mintál, Kitti/0009-0003-4739-2902} } @article{MTMT:34642191, title = {The role of intraamygdaloid oxytocin in spatial learning and avoidance learning}, url = {https://m2.mtmt.hu/api/publication/34642191}, author = {Vörös, Dávid and Kiss, Orsolya and Taigiszer, Márton and László, Bettina Réka and Ollmann, Tamás and Péczely, László and Zagorácz, Olga and Kertes, Erika and Kállai, Veronika and Marosné Berta, Beáta and Kovács, Anita and Karádi, Zoltán György and Lénárd, László and László, Kristóf}, doi = {10.1016/j.peptides.2024.171169}, journal-iso = {PEPTIDES}, journal = {PEPTIDES}, volume = {175}, unique-id = {34642191}, issn = {0196-9781}, abstract = {The goal of the present study is to investigate the role of intraamygdaloid oxytocin in learning-related mechanisms. Oxytocin is a neuropeptide which is involved in social bonding, trust, emotional responses and various social behaviors. By conducting passive avoidance and Morris water maze tests on male Wistar rats, the role of intraamygdaloid oxytocin in memory performance and learning was investigated. Oxytocin doses of 10 ng and 100 ng were injected into the central nucleus of the amygdala. Our results showed that 10 ng oxytocin significantly reduced the time required to locate the platform during the Morris water maze test while significantly increasing the latency time in the passive avoidance test. However, the 100 ng oxytocin experiment failed to produce a significant effect in either of the tests. Wistar rats pretreated with 20 ng oxytocin receptor antagonist (L-2540) were administered 10 ng of oxytocin into the central nucleus of the amygdala and were also subjected to the aforementioned tests to highlight the role of oxytocin receptors in spatial- and avoidance learning. Results suggest that oxytocin supports memory processing during both the passive avoidance and the Morris water maze tests. Oxytocin antagonists can however block the effects of oxytocin in both tests. The results substantiate that oxytocin uses oxytocin receptors to enhance memory and learning performance.}, keywords = {MEMORY; OXYTOCIN; learning; rat; amygdala}, year = {2024}, eissn = {1873-5169}, orcid-numbers = {Ollmann, Tamás/0009-0009-6798-7704} } @CONFERENCE{MTMT:34558057, title = {Neuropeptide QRFP enhances memory in passive avoidance paradigm.}, url = {https://m2.mtmt.hu/api/publication/34558057}, author = {Zagorácz, Olga and Ollmann, Tamás and Péczely, László and László, Kristóf and Kovács, Anita and Marosné Berta, Beáta and Kállai, Veronika and Kertes, Erika and Vörös, Dávid and Dusa, D and Szabó, Ádám and Lénárd, László}, booktitle = {International Neuroscience Conference, Pécs 2024}, unique-id = {34558057}, year = {2024}, pages = {195}, orcid-numbers = {Ollmann, Tamás/0009-0009-6798-7704} } @CONFERENCE{MTMT:34558123, title = {Unexpected effects of neuropeptide QRFP administration into the lateral hypothalamic area on feeding.}, url = {https://m2.mtmt.hu/api/publication/34558123}, author = {Zagorácz, Olga and Ollmann, Tamás and Péczely, László and László, Kristóf and Kovács, Anita and Marosné Berta, Beáta and Kállai, Veronika and Kertes, Erika and Lénárd, László}, booktitle = {6th Hungarian Neuroscience Doctoral Conference for Undergraduate Students, Graduate Students and Junior Postdoc}, unique-id = {34558123}, year = {2023}, pages = {107}, orcid-numbers = {Ollmann, Tamás/0009-0009-6798-7704} } @CONFERENCE{MTMT:34558097, title = {Neuropeptide QRFP affects spatial memory in rats.}, url = {https://m2.mtmt.hu/api/publication/34558097}, author = {Zagorácz, Olga and Ollmann, Tamás and Péczely, László and László, Kristóf and Kovács, Anita and Marosné Berta, Beáta and Kállai, Veronika and Kertes, Erika and Szabó, Ádám and Vörös, Dávid and Lénárd, László}, booktitle = {FENS Regional Meeting 2023 (FRM2023)}, unique-id = {34558097}, year = {2023}, orcid-numbers = {Ollmann, Tamás/0009-0009-6798-7704} } @article{MTMT:34124226, title = {Novel Noninvasive Paraclinical Study Method for Investigation of Liver Diseases}, url = {https://m2.mtmt.hu/api/publication/34124226}, author = {Győrfi, Nina Rubina and Gál, Adrián Róbert and Fincsur, András and Kalmar-Nagy, Karoly and Mintál, Kitti and Hormay, Edina and Miseta, Attila János and Tornóczky, Tamás and Nemeth, Anita K. and Bogner, Péter and Kiss, Tamas and Helyes, Zsuzsanna and Sári, Zoltán and Klincsik, Mihály and Tadity, Vladimir and Lénárd, László and Vereczkei, András and Karádi, Zoltán György and Vizvári, Zoltán Ákos and Tóth, Attila}, doi = {10.3390/biomedicines11092449}, journal-iso = {BIOMEDICINES}, journal = {BIOMEDICINES}, volume = {11}, unique-id = {34124226}, abstract = {Based on a prior university patent, the authors developed a novel type of bioimpedance-based test method to noninvasively detect nonalcoholic fatty liver disease (NAFLD).

One of the core symptoms is impaired social interaction. Since proper treatment has not been found yet, an investigation of the exact pathophysiology of autism is essential. The valproate (VPA)-induced rat model can be an appropriate way to study autism. Oxytocin (OT) may amend some symptoms of ASD since it plays a key role in developing social relationships. In the present study, we investigated the effect of the intraamygdaloid OT on sham and intrauterine VPA-treated rats' social interaction using Crawley's social interaction test. Bilateral guide cannulae were implanted above the central nucleus of the amygdala (CeA), and intraamygdaloid microinjections were carried out before the test. Our results show that male Wistar rats prenatally exposed to VPA spent significantly less time on social interaction. Bilateral OT microinjection increased the time spent in the social zone; it also reached the level of sham-control animals. OT receptor antagonist blocked this effect of the OT but in itself did not significantly influence the behavior of the rats. Based on our results, we can establish that intraamygdaloid OT has significantly increased time spent on social interaction in the VPA-induced autism model, and its effect is receptor-specific.}, keywords = {OXYTOCIN; autism; valproate; Social interaction; RAT MODEL; amygdala}, year = {2023}, eissn = {2227-9059}, orcid-numbers = {Ollmann, Tamás/0009-0009-6798-7704; Mintál, Kitti/0009-0003-4739-2902} } @{MTMT:34001562, title = {Modifications of the gastrointestinal microbiome have crucial role in the control of social behavioural processes.}, url = {https://m2.mtmt.hu/api/publication/34001562}, author = {Mintál, Kitti and Tóth, Attila and Hormay, Edina and Kocsis, B and László, Kristóf and Vízvári, Z and Lénárd, László and Karádi, Zoltán György}, booktitle = {MedPECS - Medical Conference for PhD Students and Experts of Clinical Science}, unique-id = {34001562}, year = {2023}, pages = {46}, orcid-numbers = {Mintál, Kitti/0009-0003-4739-2902; Hormay, Edina/0009-0004-0598-5061} }
