A Harrison-szabály és Poulin növekvő variancia elméletének tesztelése a Ricinidae és a Philopteridae tetűcsaládokban
(2015)A century ago Lancelot Harrison (1915) concluded that in host-parasite relationships a bigger host has bigger parasites than the small ones. This positive correlation, known as Harrison’s rule, was tested in many studies ... -
A kannabinoidok szerepe a szociális kihívásokra adott válaszreakciók szabályozásában
(2015)Previous studies showed that endocannabinoid signaling plays a role in the regulation of social behavior, predominantly aggression, although the details of this role are still to be clarified. Current pharmacological ... -
A két oktávval megemelt (rágcsálók hallásához igazított) Mozart-szonáta hatása a patkányok tanulási képességére
(2015)In humans, the so-called „Mozart effect” is understood as an effect of music to improve learning capacity and sense of time and space. The animals' spatial learning and memory performance was tested in an 8-arm radial maze, ... -
A median raphe sejtjeinek glutamaterg természete, a szerotonerg rendszer új nézőpontból
(2015)Az előagyi neuronhálózatok modulációjában fontosak a szubkortikális monoaminerg pályarendszerek, így a középagyi median raphe régióból (MRR) felszálló szerotonerg rendszer is. Nemrégiben kiderült, hogy a MRR, a tónusos ... -
A parlagi sas (Aquila Heliaca) és a pusztai sas (Aquila Nipalensis) hibridizációjának molekuláris vizsgálata
(2015)For a long time researcher investigate the question of hybridization, especially since the molecular techniques have been improved. Due to these improvements it is possible to study it’s effects and role in the evolutionary ... -
A viselkedési konzisztencia környezeti meghatározottsága
(2015)While the number of studies reporting the presence of individual behavioural consistency (animal personality, behavioural syndrome) has boomed in the recent years, there is still much controversy about the proximate and ... -
Csíráztatási protokoll kidolgozása herbáriumi maganyagokra
(2015)According to the human impact, the extinction rate of the species was increased. For such reason the protection of remained species and habitats came to focus but for such work the knowledge of biology and ecology of the ... -
Dominancia vizsgálata zebrapintyek között
(2015)Social hierarchy is one of the most often used terms, to describe the relationships among animals living in groups. However, the bigger the groups are, the bigger the chance is that the observed structure will not be ... -
Drog rezisztens sejtek célzott elpusztítása és "átprogramozása" MDR-szelektív vegyületekkel
(2015)The efficacy of drugs used to treat malignancies is often hampered by the emergence of the so-called multidrug resistance (MDR). Cancer cells with MDR phenotype overexpress a transmembrane protein, P-glycoprotein (Pgp, ... -
Felszíni szennyvizekben megjelenő gyógyszerek és gyógyszermaradványok kimutatása csillós eukarióta modell-rendszerben
(2015)In this work the unicellular Tetrahymena pyriformis was studied for chemotaxis, phagocytosis, proliferation and chemotactic selection in the presence of different antibiotics and steroid hormones. This cell represents an ... -
Fotoaktív glutamát vegyületek dendritikus integráció méréséhez
(2015)Photoactive cage molecules can be bound to both excitatory and inhibitory neurotransmitters and their analogues, and used as carrier molecules, thus creating a caged neurotransmitter that is excited when exposed to light, ... -
Gyűrűsfarkú makik (Lemur Catta) kooperációja a dominancia, szociális és rokonsági viszonyok függvényében
(2015)The evolution of cooperation is a controversial part of behavioural biology. Hamilton‟s rule explains well the phenomenon of cooperation between related individuals (kin selection theory). Among non-related individuals ... -
Hazai galamb-cirkovírusok genetikai diverzitásának vizsgálata
(2015)The objective of my diploma work was the investigation of the genetic diversity among Hungarian pigeon circoviruses (PiCVs). I examined pigeon samples that had been found positive in the laboratory previously, together ... -
Helyspecifikus mesterséges nukleáz használatán alapuló in vivo célzott génmódosítási technológiák kidolgozása egérben
(2015)In the past two decades rapid development occurred in the research methods of genetics and molecular biology and gentechnology was not an exception. The progression of gentechnology mainly caused by the accelerated research ... -
Hüllők és kétéltűek PCR-es szűrése adeno- és parvovírusokra, a szakállas agáma-adenovírus genomjának analízise
(2015)Adenoviruses can be found in every Vertebrate class. Family Adenoviridae has 5 accepted and one proposed genera. My work was focusing on Atadenovirus genus because this genus is thought to have coevolved with squamate ... -
Membrán-transzporterek genetikai variánsainak vizsgálata vérképző szervrendszeri megbetegedésekben
(2015)ATP-binding cassette (ABC) transporters, present in all living organisms, take part in cell protection and metabolism. Their main task is to pump their substrates in the extracellular space with an ATP-dependent manner. ... -
