Construction of molecular tools based on CRISPR/Cas9 system for epigenetic modulation of gene expression
Vanja Tadić
Repurposing of platforms for targeted genome engineering, zinc finger nucleases (ZFNs), transcription activator-like nucleases (TALENs) and especially CRISPR/Cas9 system, has enabled targeted manipulation of epigenetic marks and new insights into epigenetic regulatory mechanisms. In this work, I have fused the catalytic domain of human TET1 (Ten-Eleven Translocation 1) protein Cterminally to the catalytically inactive Cas9 (dCas9) from Streptococcus pyogenes to create the dCas9- ...
Cosmic evolution of active galactic nuclei detected in the radio waveband
Cosmic evolution of active galactic nuclei detected in the radio waveband
Bruno Šlaus
A major topic in the field of astrophysics is understanding the evolution of the Universe through cosmic time. Throughout the evolution of the Universe and galaxies, among the most interesting objects are galaxies containing active, super-massive black holes in their galactic centers, called active galactic nuclei (AGN). We model the evolution of AGN by constructing their radio luminosity functions. We use radio surveys of varying area and depth, namely the deep COSMOS survey of 1,916 AGN...
Crosstalk of gene polymorphisms with RNA and protein phenotypic characteristics
Crosstalk of gene polymorphisms with RNA and protein phenotypic characteristics
Marina Rudan
Both RNA and protein molecules can misfold into non-functional conformations. Since DNA is transcribed into RNA to direct the biosynthesis of proteins, functional cells require the maintenance of DNA, RNA and protein homeostasis. Here, it is explored whether DNA polymorphisms can impact upon RNA and protein conformation to the extent of displaying phenotypic changes. It has been found that this is a multifaceted process. Mutation-induced protein conformational ...
DEFINING THE MECHANISM OF POLAR CHROMOSOME CONGRESSION DURING PROMETAPHASE
DEFINING THE MECHANISM OF POLAR CHROMOSOME CONGRESSION DURING PROMETAPHASE
Isabella Koprivec
Chromosomes that first attach to the mitotic spindle behind the spindle pole (i.e., polar) are delayed in alignment and prone to segregation errors. Nevertheless, their congression mechanism remains elusive. Using a unique combination of advanced microscopy techniques, I showed that polar chromosomes rely on the pivoting of chromosome-attached astral microtubules around the centrosome to cross the pole. By altering the KIF11/Eg5 activity to reverse, restore, or block spindle elongation, I...

DISBIOZA CRIJEVNOG MIKROBIOMA U UPALI PROUZROČENOJ ZDRUŽENIM DJELOVANJEM INHALACIJSKIH ANESTETIKA S TEŠKIM METALIMA U ŠTAKORA
Dyana Odeh
Narušavanje crijevnog mikrobioma snažno je povezano s razvojem patofizioloških bolesti posredovanim oksidacijskim stresom (OS) u ljudi i životinja. Temeljem toga, cilj rada bio je dublje razumijevanje odnosa između crijevnog mikrobioma i redoks homeostaze prouzročene prekomjernim unosom teških metala (TM; Fe i Al) te izlaganja inhalacijskim anesteticima (IA) kroz praćenje strukturnih i funkcionalnih promjena crijevnog mikrobioma, crijevne barijere, OS, upale, regulacije...
DIVERSITY OF DIATOM AND BACTERIAL COMMUNITIES ASSOCIATED

DIVERSITY OF DIATOM AND BACTERIAL COMMUNITIES ASSOCIATED WITH LOGGERHEAD SEA TURTLES (CARETTA CARETTA)
Klara Filek
Loggerhead sea turtles are ancient marine reptiles inhabiting the oceans worldwide. They are colonized by microorganisms both in the gastrointestinal tract and on their carapace and skin. In this thesis that consists of four scientific publications, the loggerhead sea turtle-associated diatom and bacterial communities were investigated by high-throughput sequencing of chloroplast rbcL gene and 16S rRNA gene, and cultivation. The culture-independent approach has shown that loggerheads...

DJELOVANJE STROBILURINSKIH FUNGICIDA NA BIOKEMIJSKE, STANIČNE I POPULACIJSKE BIOMARKERE ENHITREJA VRSTA Enchytraeus crypticus i Enchytraeus albidus
Marija Kovačević
Enhitreje su bliski srodnici gujavica te modelni organizmi u ekotoksikološkim istraživnjima tla. Iako imaju važnu ulogu u ekološkim sustavima tla, djelovanje pojedinih zagađivala, posebice strobilurinskih fungicida nedovoljno je istraženo. Stoga je cilj ovog doktorskog rada nadopuniti postojeća istraživanja novim znanjima o utjecaju strobilurinskih fungicida na enhitreje vrsta E. crypticus i E. albidus. Razvijena je metoda za mjerenje promjena aktivnosti mehanizma ...
DOMAIN-SPECIFIC INTERACTIONS OF BPM1 WITH DMS3 AND RDM1 IN RNADIRECTED DNA METHYLATION
DOMAIN-SPECIFIC INTERACTIONS OF BPM1 WITH DMS3 AND RDM1 IN RNADIRECTED DNA METHYLATION
Mateja Jagić
BPM1 protein belongs to the MATH-BTB protein family, characterized as adaptors of CUL3- dependent E3 ubiquitin ligase complex responsible for recognizing and directing substrates for proteasomal degradation. An initial mass spectrometry experiment identified a key component of the RdDM, the DMS3 protein, as a potential BPM1 partner. Since RdDM is the major epigenetic mechanism responsible for de novo DNA methylation in plants, the goal of this work was to further investigate the role of...

Defekti i nanostrukture u metalnim oksidima pogodnim za organske solarne ćelije
Defekti i nanostrukture u metalnim oksidima pogodnim za organske solarne ćelije
Daniel Meljanac
Da bi tanki film metalnog oksida ušao u upotrebu kao prozirni i vodljivi sloj za solarne ćelije, način njegovog formiranja mora garantirati vrhunske performanse ostvarene na jednostavan način i sa perspektivom jednostavnog povećavanja proizvodne skale. Hipoteza rada je da se ovo može postići preciznim podešavanjem procesa formiranja i jednostavnim postupcima naknadne obrade. Posebnost organskih solarnih ćelija je mala difuziona dužina fotogeneriranih nosilaca naboja (kratko vrijeme...
Depozicija i karakterizacija nanokristalnog silicija
Depozicija i karakterizacija nanokristalnog silicija
Davor Ristić
Deponirani su tanki filmovi silicija, silicijevog dioksida i silicijem bogatog oksida (SiOx) metodom LPVCD (Low Pressure Chemical Vapor Deposition). Depozicije su se odvijale pod različitim uvjetima u okviru kojih se varirao sastav i parcijalni tlak radnih plinova i temperatura depozicije. Termičkim oporavkom SiOx slojeva na temperaturama od 800 do 1200 oC dobile su se različite nanočestice silicija. Navedene nanočestice karakterizirane su pomoću Ramanove, infracrvene i apsorpcijske...
Derivation of a homogenized elasto-plastic plate model
Derivation of a homogenized elasto-plastic plate model
Marin Bužančić
In this thesis we consider a lower dimensional homogenized thin plate model within the framework of linearized elasto-plasticity. Starting from the energetic formulation of the quasistatic evolution, we analyse the behavior of the elastic energies and dissipation potentials, as well as the displacements and strain tensors, when the period of oscillation of the heterogeneous material and the thickness of the thin body simultaneously tend to zero. In order to derive convergence results for...
