New paper accepted in Fish Physiology and Biochemistry

A new paper of our group was accepted for publication in Fish Physiology and Biochemistry, entitled "In vitro toxicology test system based on common carp (Cyprinus carpio) sperm analysis".


Abstract
The effect of heavy metals on the motility parameters of common carp sperm was investigated. In vitro test systems are widespread in ecotoxicology, and fish sperm can be a suitable model. For this reason, studies had been carried out in this topic; however, the published methods are not standard in several aspects (donor species, measured endpoint, etc.). In this study, a previously published toxicology-aimed sperm analysis protocol was tested to examine the effect of heavy metals (arsenic, cadmium, chromium, copper, mercury, nickel, zinc,) on common carp sperm. According to our results, PMOT is the most sensitive of the investigated parameters: dose-response was observed in case of each metal at low concentrations, already after 30 min of exposure. VCL was less sensitive: lower effects were observed at the same concentrations compared to PMOT. Among the examined parameters, LIN was the least affected: a dose-response was observed only in case of arsenic and mercury. The same sensitivity of motility parameters was observed on zebrafish sperm previously. Moreover, we found that PMOT, VCL, and LIN of common carp sperm were affected at the same concentrations as it had been observed in zebrafish, when the identical analytical protocol was applied. The only exception was As3+, where common carp sperm proved to be more sensitive: lower concentrations already reduced its motility parameters. Consequently, PMOT of common carp sperm is an accurate and fast bioindicator of aquatic pollution.

55th Annual meeting of the Society for Cryobiology (CRYO2018)


Jelena and Zoran have participated at the 55th annual meeting of the Society for Cryobiology (CRYO2018) organized in Madrid, Spain (10th – 13th July). 

During the symposium, they gave oral presentations of two papers done in collaboration with our colleagues from Japan and Czech Republic. 

We are especially proud of Zoran who was awarded the prestigious Peter L. Steponkus Crystal Award for the best presentation.

Farewell to Eszti

After 6 years we have to say goodbye to Eszti who has found a new job as of July 16th. Eszti has been part of our team since the very beginning in 2012 and she has contributed to the development of our group both scientifically and personally. Eszti finished her master's in biotechnology under Ákos's supervision in 2013 and enrolled into her PhD studies the same year. Her topic was the vitrification of fish sperm and she has successfully defended her dissertation in 2017. In addition to her PhD topic she worked with our team on various projects and has been very active in the promotion of our work to the general public. But above all this, she was and continues to be a very good friend. We will miss you, Eszti, and we wish you all the best in your career.

Welcome Betti and Ilija

We are more than happy to announce that our team is richer by two new members, Bernadett Pataki and Ilija Šćekić. They have already been included in the work of our group for few months, but from the next academic year, they will be PhD students at the Department of Aquaculture, Szent István University. Welcome :)

Welcome dinner for Betti and Ilija
