Offer Description
The effect of selected antioxidants on the cryopreserved animal sperm quality

Workplace: Faculty of Biotechnology and Food Science, Slovak University of Agruculture in Nitra
Field of Study: Biotechnology
Study program: Agrobiotechnology
Form of study: full-time
Language: Slovak
Abstract
The effective cryopreservation of the reproductive biological material of some livestock species has not yet been fully mastered. The result is reduced survival and quality of mainly frozen / thawed cells (sperm) of livestock (rabbits, horses). The primary goal of the submitted PhD. topics are optimization of cryopreservation methods (programmable and manual) and quality assessment of reproductive biological material - sperm (using methods: CASA, Flow cytometry, light, fluorescence, confocal and electron microscopy, PCR, cryoprotection - vitrification and programmable freezer) before and after freezing. We will give priority to application of antioxinads (astaxantín, berberín and mitotempo) in cryopreservation solution and to use only Slovak breeds of farm animals (rabbits, horses), whose numbers of individuals we consider endangered or risky based on monitoring. Our results will make it possible to increase the quality of frozen samples, expand the gene bank of animal genetic resources and save the original Slovak breeds.
Vplyv vybraných antioxidantov na kvalitu kryouchovávaných spermií zvierat
Abstrakt
Efektívne kryouchovávanie reprodukčného biologického materiálu niektorých druhov hospodárskych zvierat zatiaľ nie je úplne zvládnuté. Výsledkom je znížená prežívateľnosť a kvalita hlavne zmrazených/rozmrazených buniek (spermií) hospodárskych zvierat (králiky, kone). Primárnym cieľom predkladanej PhD. témy je optimalizácia metodík kryouchovávania (programovateľné a manuálne) a hodnotenia kvality reprodukčného biologického materiálu – spermií (využitím metód: CASA, Flow cytometria, svetelná, fluorescenčná, konfokálna a elektrónová mikroskopia, PCR, kryouchvávanie - vitrifikácia a programovateľný zmrazovač) pred a po zmrazení. Prioritne sa budeme zameriavať na aplikáciu vybraných antioxidantov (astaxantín, berberín a mitotempo) do zmrazovacích riedidiel a využívať slovenské plemená hospodárskych zvierat (králiky, kone), ktorých počty jedincov na základe monitoringu pokladáme za ohrozený či rizikový. Naše výsledky umožnia zvýšiť kvalitu zmrazovaných vzoriek, rozšíriť génovú banku živočíšnych genetických zdrojov a záchranu pôvodných slovenských plemien.
