Evoluce nočního kvetení
Výsledek obhajoby: NEOBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 7. 9. 2026Night flowering has fascinated researchers since at least the 19th century, but since then ithas remained a relatively understudied phenomenon. This bachelor's thesis therefore attempts to summarize the available literature ... -
Environmental adaptation of the marine phytoplankton and its impact on the marine carbon pump
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 7. 9. 2026Calcareous nannoplankton are major contributors to marine carbon cycling through their roles in both the organic carbon pump and the carbonate counter pump. Their fossil remains preserve records of past oceanographic and ... -
Proteomová analýza buněčné proliferace a diferenciace na modelech nervových kmenových buněk a nádorových buněk
Výsledek obhajoby: UZNÁNO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 7. 9. 2026CoNcLUsIoNs In protein profiling of neural stem cells using 2-dimensional gel electrophoresis and mass spectrometry, constitutively expressed proteins in 66 protein spots were identified. Most of the individual protein ... -
Tvorba biofilmov a virulenčné faktory u kvasinky Nakaseomyces glabratus (Candida glabrata)
Výsledek obhajoby: NEOBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 4. 9. 2026Nakaseomyces glabratus, one of the common causes of yeast-related diseases, is related to a non-pathogenic species Saccharomyces glabratus. Normally, it inhabits mucosal epithelia as a comensal organism, however, risk ... -
Sources of variation in pollen transferred on pollinator bodies
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 3. 9. 2026Pollen transfer on the pollinator's body is a highly complex and stochastic process, influenced by a wide range of different factors. Moreover, significant amounts of pollen are lost during the transfer process, and only ... -
NMR studies of photoresponsive molecular systems and the application of 31P NMR in structural analysis
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 3. 9. 2026Molecular photoswitches are key components of modern photoresponsive systems, enabling reversible control of molecular properties using light. In particular, azobenzenes undergoing E/Z isomerization are widely used in ... -
Analysis of the mature and zymogenic forms of the SARS-CoV-2 main protease
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 3. 9. 2026In 2019, the COVID-19 pandemic emerged. Its causative agent, SARS-CoV-2, a betacorona- virus with a positive-sense single-stranded RNA genome, utilizes a polyprotein strategy. One of the proteases responsible for processing ... -
Ecology of diatoms from glacier fed streams
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2026)Datum obhajoby: 2. 9. 2026The rapid retreat of glaciers worldwide threatens the specialized ecosystems of glacier- fed streams (GFSs). While benthic diatoms form the autotrophic foundation in many of these extreme habitats, their biodiversity and ... -
Hemové senzorové proteiny jako potenciální markery oxidačního a buněčného stresu indukovaného ionizujícím zářením
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2023)Datum obhajoby: 22. 9. 2023[IN CZECH] Ionizing radiation is a potential inducer of the oxidative stress processes in cells. As a result, reactive radicals are formed in the intracellular space modifying the essential biomolecules. Ionizing radiation ... -
Syntéza látek strukturně podobných alkaloidům s kvarterními uhlíkovými centry
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Přírodovědecká fakulta, 2023)Datum obhajoby: 21. 9. 2023Synthesis inspired by natural products has a long tradition in drug development. Because the structure of bioactive natural compounds is often very complex, preparation of their derivatives requires the development of ...
